Re: Import error

[Emily]

Kurtis, Adrian and Daniel,

thank you so much for your help, it actually worked
I have programmed in java 70% of my life

Now I want to send sms to my users when they sign up
in the website. There is some package I have seen which looks
like it is from an email to the phone. Does it work with messages
from a website to a phone...

Re: Import error

This is the class I created...

import string
import random

class Helpers:

def random_password():
'''a method to generate random password'''
lengthOfPassword = random.randint(6,10)
password_len = lengthOfPassword
password = []

for group in (string.ascii_letters, string.punctuation,
string.digits):
password += random.sample(group, 3)

password += random.sample(
 string.ascii_letters + string.punctuation + string.digits,
 password_len - len(password))

random.shuffle(password)
password = ''.join(password)

return password

def sendSMS():
'''a method to send sms to a user'''
pass

Re: Import error

[Emily]

so your point is that I should post my code.
When I did that some time, I was told that
the people who were trying to help me did not
want to know what is in my code so I should just
explain what I want them to help me with.
But thank you any way, you point has been driven home.

Dear Marcin,

I do not understand.
I think I have done everything right and I am trying to find
the source of the error where if there is someone who has
experienced it they might be knowing where it is coming from..

Re: How to generate secure passwords

[Emily]

I want to sell passwords to users. If I can generate passwords
for them that can last for a specific period of time (the time they
have paid for) this would be good.

If the user generates there own I cannot restrict them from viewing
certain content don't want them to view...

My problem is that a user has to pay some money to view content on
my page for a certain period of time and this looks like a good way; a
password that can expire... When it expires, they have to buy another
pass word.

How to generate secure passwords

[Emily Namugaanyi]

Hi Django users,

I am working on a project that as to generate secure passwords
(passwords that cannot be hacked) every time a user register and the
password lasts for a period of time. S,here I am wondering whether
django has a provision for this or I need to find another way...
Thank you for your time

Re: How to execute some user defined codes (functions) when Django boot?

Hi,

I still don't really understand what you are trying to do, but it
sounds like Mathieu does and has offered you some pretty useful
advice.

If his link below helps you fix what you are trying to do, please let
us know what you did (this is really useful for others with the same
problem), and if not, please come back and ask again.

Hi,

I don't know how to help you, but I think it is because you haven't
explained what you want to do thoroughly enough.

What do you mean by a plugin system, and what do you mean by
registering them with the app on boot up? Are you talking about
including another python module in your code? Or perhaps including
another django app in your code?

Can you give us a bit more information (and maybe examples) of what
you are trying to do.

Cheers,

I actually like that idea. Like a linked list. It would mean the
django query could be simpler, and the post processing wouldn't be too
bad.

Thanks - yeah if I can't figure it out I may have to go for adding
another field into the model. It would have to be another datetime
field rather than an is_current flag because an is_current flag
wouldn't help me for queries in the past (if that makes sense).

It doesn't have to be, but I would like to try to use a single query

The thing is, there could be say 3000 distinct foos in the table. It
would take ages to return the results if I did this. I was hoping to
do it in one query. Might have to revert to SQL if I can't do it using
the django ORM.

confusing query involving time ranges

[Emily Rodgers]

Hi,

I am a bit stuck on this and can't seem to figure out what to do.

I have a model that (stripped down for this question) looks a bit like
this:

class State(models.Model):
first_dt = models.DateTimeField(null=True)
last_dt = models.DateTimeField(null=True)
foo = models.CharField(FooModel)
bar = models.ForeignKey(BarModel, null=True)
meh = models.ForeignKey(MehModel, null=True)

This is modeling / logging state of various things in time (more
specifically a mapping of foo to various other bits of data). The data
is coming from multiple sources, and what information those sources
provide varies a lot, but all of them provide foo and a date plus some
other information.

What I want to do, is given a point in time, return all the 'states'
that span that point in time. This seems trivial except for one thing
- a state for a particular 'foo' may still be persisting after the
last_dt until the next 'state' for that 'foo' starts. This means that
if there are no other 'states' between the point in time and the start
of the next state for a given foo, I want to return that state.

I have built a query that kindof explains what I want to do (but
obviously isn't possible in its current form):

dt = '2010-08-12 15:00:00'

lookups = State.objects.filter(
Q(
Q(first_dt__lte=dt) & Q(last_dt__gte=dt) |
Q(first_dt__lte=dt) &
Q(last_dt=State.objects.filter(foo=F('foo')).filter(first_dt__lte=dt).latest('last_dt'))
)
)

I know this doesn't work, but I think it illustrates what I am trying
to do better than words do.

Does anyone have any advice? Should I be using annotate or something
to show what the last_dt for each foo is? I might be being really
stupid and completely missing something but I have been trying to
figure this out for too long!

Cheers,
Emily

Hi,

I think the query you are looking for is quite simple.

>From what I understand (correct me if I have got it wrong), your
models are something like this:

class ChildModel(models.Model):
foo = models.CharField(max_length=20)
parent = models.ForeignKey(Parent, null=True,
related_name="child")

class ParentModel(models.Model):
bar = models.CharField(max_length=20)

To get children without parents, you just do:

ChildModel.objects.filter(parent__isnull=True)

The first time I read your question I was really confused (I think
because you had got so many replies that weren't answering your
question, I thought it was more complicated than it actually was), and
thought you had got your child / parent analogy the wrong way and were
actually asking how to do the query from the other side (ie actually
getting childless parents), which is a bit more complicated, but not
much, so I figured out how to do that too (if you care).

To get the childless parents you do:

childless= ParentModel.objects.filter(child__isnull=True)

Be warned though, if you want to use it to find the parents that have
children (ie aren't childless), you *don't* want to do this:

parents = ParentModel.objects.filter(child__isnull=False)  # won't
give you what you expect

because if the foreign key is not one to one, then you will get the
multiplicity for want of a better word. i.e. if you have one parent
record that is a ForeignKey from two children, then that parent will
be returned twice. To eliminate these duplicates, you should do:

parents = ParentModel.objects.filter(child__isnull=False).distinct()

Hope that helps in some way (rather than confuses),
Em

I think he stopped helping when he started using phrases like 'crystal
ball' and 'wild-guess programming'. They are hostile responses.

The django-users group used to be a friendly place where people could
ask sometimes daft, sometimes difficult questions and get a useful
reply (in either case). This has been happening less and less lately.
People get responses telling them to learn how to post a question, or
just critising them for not being specific enough about what they want
to know, and this is just a bit too hostile IMO. If you think someone
hasn't provided enough information, it is helpful to ask them direct
questions that they can answer to provide a useful context (without
making them feel stupid). Often they aren't familiar with django /
python / web development, and don't really know what is required for a
useful answer to be given. It is our job to help them, not scare them
away.

One of the (many) great things about django is the community. Please
can we be friendly and helpful here instead of answering questions
with unhelpful responses?

As I said, we aren't doing his coding for him, more giving examples of
ways to query this kind of thing. Sometimes (particularly if you are a
newbie) it is difficult to explain all of your requirements for a
problem in a concise way to a news group in order to satisfy people
who don't do 'wild-guess programming', and have to simplify things a
lot as it is because you may not want to share your code with the
world. Often in order to give a helpful reply to these types of
questions (rather than a dismissive response) you have to make some
assumptions. Presumably the OP will be able to tell if these
assumptions are reasonable, and if not, this discussion may help to
improve his design.

My assumptions came from analogous cases in the real world. Often
companies group together to give some kind of club that customers can
sign up to to get benefits of discounts from all companies in the
group (reward cards are the most obvious case I can think of).

If this is Derek's meaning then the passenger (or I think user) may
have memberships to any number of such reward schemes. Also, and
airline may be in more than one alliance (or group that offers a
certain discount for members). The purpose of the query is to see
which reward schemes the passenger is a member of, and what discount
they qualify for (the maximum discount would normally prevail). In my
mind, the membership sits with the user object, and a passenger record
is merely showing that the user is booked onto a flight (so could be
renamed 'FlightBooking').

I may be completely wrong of course, and it would be interesting to
hear from the OP what his thoughts are.

I reckon he probably wants to do is split passenger up:

class Passenger(models.Model):
customer = models.ForeignKey(User)
flight = models.ForeignKey(Flight)

and have memberships as an attribute of the user. Then you would want
to pass the flight number to the function that determines the
discount.

You do have a point, but I think he is wanting a vague idea of how to
go about it rather than for us to write his code for him. Or maybe get
a discussion going about the pros and cons of different ways of
querying.

How about creating this as a method of the passenger model:

def calculateDiscount(self):
max_discount = 0
# discount_with = None
flight_allies = self.flight.operator.membership.all()
# you may want to make the above "memberships" (with an s) to be
consistent or it will come back to bite you in the bum!
users_allies = self.memberships.all()
for fa in flight_allies:
if fa in users_allies:
if fa.discount > max_discount:
max_discount = fa.discount
# discount_with = fa
return max_discount

I put the 'discount_with' variable in so that if you wanted to know
which membership was used for a discount you can (just need to figure
out the best way to return it - I tend to use objects or dicts). I
haven't in any way tested it, so there may be silly errors, but you
get the idea. There are probably also better (more efficient) ways,
but this is what would occur to me!

To use this form a view, you would do something like:

passenger = Passenger.objects.get(pk=57)
discount = passenger.calculateDiscount()

Presumably you know how to get the id of the logged in user (you would
just put that in instead of 57).

To actually help you though, /djvu_ulib/16003525/0001.djvu isn't
being matched because there isn't a regex for it in the list!

There are two similar regexes in your list:

> ^ulib/(?P\d+)/?$
> ^djvu/(?P\d+)/(?P\d{8})(?P\w{7}).djvu/?$

Presumably you meant the second, but it wouldn't match because it has
8 chars before .djvu not 7, and the url has djvu/ not djvu_ulib/.
Also, I don't think you need to put "/?" at the end of the url even if
you may send it GET data.

It looks like you need to either change your url or the regex for it.

There is also a lot of inconsistency in your naming conventions for
the groups in the regex (sometimes page_id sometimes pageId). It is
usually best to decide to use one and stick to it so you don't have to
keep going back to check which it should be.

HTH,
Emily

That does pretty much the same as above (although granted it doesn't

Thanks for the suggestion. I have managed to get the field names at

looping through non-null fields

[Emily Rodgers]

Hi,

As per usual, I am probably just being really dappy, but I can't see a
good way to do this.

I have a model that has about 10 fields, and I may be populating each
record with at least one field, but probably less that 4 (could be any
4 of the 10 though). The others will be null or empty strings. Some of
the fields are foreign keys, and some are text.

Anyway, I wish the unicode method of the model to return:
"""
field_a = value_of_a,
field_c = some_other_value
"""
where field_a, and field_c are the only not null fields (or fields
where the strings are not empty) for the record (if that makes sense).

The only way I can figure out how to do it (apart from lots of
"if,elif"s, hard coding the fields) is:

non_null = [(attr, getattr(self, attr)) for attr in vars(self) if
attr != 'id' and attr[0] != '_' and getattr(self, attr) and getattr
(self, attr) != '']

This returns the data I want but it is returning the raw values from
the database which is a bit nasty, and I would have to do a lot of
post processing to make both the field name and the value pretty.

Is there a nicer way to loop through the model attributes (rather than
db fields) that would give the objects for the foreign keys instead of
the ids?

Not sure I know how to help, but I don't think you are giving enough
information for those who may be able to help to answer this.

What happens? does the url actually get called (and fail to return
useful data)? Is something being returned that isn't valid xml?

If the url isn't actually getting requested, then the problem is
probably outside of django.

Realised I was being dumb, and you can follow the foreign keys to get
more useful values by specifying them when you pass the strings to
values() :-)

Ah your suggestion is exactly what I am after :)

Although, I think if there are foreign keys (or choices for the field)
etc, values() tends to return the id of the value, which means I have
to go figure out which model it relates to, then find that record, and
get the user friendly data (I am returning this using JSON to a ExtJS
script). This starts to make it expensive again.

I will have a play with your suggestion though - thanks :)

QuerySets with annonate, count() and multiple fields

[Emily Rodgers]

Hello,

I am a bit stuck on something that I think ought to be really easy (so
I am probably being really stupid!).

I am trying to write a view for a model such that I can pass the view
(via post data) a (or an unknown) number of fields of that model, and
receive back a list of dictionaries of distinct values for those
fields and the number of times that combination of values appears.

So, suppose the model was for holding data about cars, and it had
fields 'manufacturer', 'model', 'fuel_type', 'colour', 'n_of_doors',
etc where the fields had appropriate field types (a mixture of
different field types), I would want to be able to pass the view for
example groupBy=['colour', 'fuel_type'], and it would return a dict of
distinct colour/fuel type combinations and how many cars there are in
the db with those combinations, eg. [{'colour': 'red', 'fuel_type:
'diesel', 'count': 14}, ...].

To me it seems like the kind of thing you would want to use annotate
and Count for, except Count takes one field not multiple fields.

I tried using values() to limit the fields, then python to do the
counting / distinct bit, but it is annoying because I want to be able
to tell it to return the unicode values for foreign keys etc. rather
than ids that would then need to be looked up. Also it is way too
slow.

I am trying to figure a way to do this that is reasonably fast because
I am trying to filter a lot of data. Am I missing something? I haven't
been using python / django much lately so I am probably thinking the
wrong way!

Any help would be appreciated :)

Hi,

Rather than listing all the key word arguments (kwargs) like that, you
are better doing it like this:

import logging # probably a better way than writing to debug.txt, but
clearly it is personal choice

def __init__(self, *args, **kwargs):
instance = getattr(kwargs, 'instance')
logging.debug("First name: %s" % instance.user.first_name) # I
like to know what it thinks it is printing!
logging.debug("Last name: %s" % instance.user.last_name) #
obviously you can change str if you like
super(ProfileForm, self).__init__(data, *args, **kwargs)

I don't know if this will fix your problem (hard to say without
visibility of the view), but it may be that you have forgotten one of
the kwargs. If you want to add extra parameters, or set them to
specific values you can still do this before calling init.

HTH,
Em

I would second this. but also if you do the django course, take a
python book with you - then if you don't get something you can just
look it up in the book quickly (the python website would also do, it
just depends on whether you prefer to learn from books or the web).
Remember, the people teaching the django course will know python, so
will be able to give you a bit of guidance if you get really stuck,
but if you go on the python course, it won't necessarily help get you
up and running with django. The poll tutorial on the django website is
brilliant for showing the different features and getting you started
though.

If you have no programming experience and don't know python, the
django course will be a lot to take in at once.

field order:ModelForm

[Emily Rodgers]

Hi,

I am using django 1.0.2, and I was wondering if it is possible to
change the order of the fields (it seems you can do this in the dev
version)?

I have added an extra field in my form (that doesn't actually
correspond with a field in the model). It is being listed after the
model fields, and I would like it to go before.

I tried adding a fields attribute to the Meta class (which I think is
what you would do in the dev version), but that didn't work.

Is the only way to do this to just create a normal form and do the
model instance interface manually? I am using an extJS frontend and
JSON to pass the values across (using the ExtJsonEncoder from django
snippets).

I think I am having a slow brain day so please excuse me if I am being
really dumb!

Hello,

Wouldn't you want the 'dialed' to be a many to many field so that one
phonebook entry could be used for more than one user?

class Phonebook(models.Model):
person_company = models.CharField(blank=True,max_length=30)
address = models.CharField(blank=True,max_length=50)
e_mail = models.EmailField(blank=True,max_length=70)
number = models.CharField(unique=True,max_length=15)
dialed = models.ManyToManyField('PhonebookStat')
def __unicode__(self):
return self.person_company

class PhonebookStat(models.Model):
username = models.CharField(max_length=30)
number = models.CharField(max_length=15)
dialed_times = models.IntegerField(max_length=10)
class Admin:
pass

I haven't really used the admin app for ages, so probably not the best
person to advise on that, but I can't see how the code you have
written would work. You need to have some kind of filter on the dialed
field.

HTH a bit,
Em

Yep, but a lot of the examples / how-tos I have found are from 2007
before the forms changed in django. Admittedly, extjs has changed a
lot more than django (they pretty much scrapped the original design
and restructured the object heirarchy for extjs 2).

Yep - as I said, I am fairly familiar with django, I have been using
it for over a year and have built 3 or 4 fairly big apps. I have
already been using django with extjs for displaying data (pretty much
how you describe above), however the thing that is slightly more
tricky is how best to handle forms.

Extjs does its own form handling (validation / widgets etc), and it is
tricky to know whether it is best to get django to do the translation
into extjs like data (maybe create an as_ext() method, analogous to
as_table() for rendering the form), or get extjs to understand the
django form data. I also need to consider what to do about validation
(it doesn't seem very dry to make extjs do the validation, but it can
do 'as you type' validation which is quite nice for the user
interface).  Has anyone had actually done this before recently? If so,
do they have any advice on which way to go? Or unforseen problems with
m2m fields etc?

On the extjs forums, the django examples are aimed at people who are
familiar with ext js but not django and don't really offer a lot of
help for the actual integration, so I was hoping that on the
django-users forum, there might be someone who would be able to offer
advice for someone familiar with django, but less so with extjs.

I will post a how-to somewhere when I have figured out what the best
way is (currently reading up / playing with extjs forms a bit more).

forms with django and extjs 3.0.0

[Emily Rodgers]

Hi all,

I am currently working on some web apps that use django for the back
end, and extjs for the front end (using JSON to pass data between the
two).

I am getting to the point where I am going to have to start doing some
form integration. Has anyone done this lately (with the latest version
of extjs)? If so, how did you go about it? I have looked on the web,
but most of the extjs / modelform examples are using either an old
version of django or an old version of extjs, both of which have
undergone fairly backwards incompatible changes in recent revisions. I
just thought that I would ask here before spending lots of time trying
to figure it out from scratch.

I have been using django for a year or so, but I am fairly new to
extjs, and the oo style of coding javascript (more like java / C#), so
I am playing catch up, and any help or advice would be gratefully
received.

I think for my system it isn't too much of a problem because I only
need to add / delete m2m relationships from my main database (not
secondary), but I will have to make sure I document it well! As I have
said before, I am so happy that someone is working on this because it
will make django so much more flexible. Thanks for your work Alex, it
is much appreciated.

I have figured out why the m2m field problems were happening (although
not fixed it elegantly yet). When I figure out how to prevent the
problem, I will reply to the other thread (where my suggested
workaround it).

Hi Richard,

I have been having a go at this lately [1], and what I posted seems to
work to an extent, but I am currently having some m2m field problems
(not problems with foreign keys though), so what I posted may be
flawed.

Alex G is working on getting proper support added to django for google
summer of code 2009, so hopefully it will be in a future release of
django :-)

Hi,

I only recently realised that a django subreddit existed, and since
then I have been learning interesting new things from it, so I thought
I would share it for the benefit of those of you that don't read
reddit:

Hi,

I have tried implementing this, but I am running into the problems
that others have about too many idle MySQL connections. Is there an
easy way to get around this?

Alex - you mention something here [1] about needing to track the
connections (that are not the default connection). Should I do
something analogous to the connection_counter attribute of the
django.db.models.Manager class?

Often with my apps I need to have a python script that is not part of
the web app (poking data in from logs, housekeeping scripts, etc). I
don't really know how your cli works, but you probably need to put
this in the script that takes the user input:

from django.core.management import setup_environ
import settings
setup_environ(settings)

This will load your settings file.

Thanks - it is great that you are working on this because it is one of
the few things that I find a little frustrating about django
(otherwise I am a big fan and often bore my co-workers who prefer to
code in perl - strange people).

Thanks Alex. I don't think I can wait that long so it looks like I am
going to have to get my hands dirty!

Is this [1] a sensible starting point?

Hi,

Alex - do you know roughly when this is likely to be incorporated into
django? I am working on a project that is going to need to connect to
multiple databases (I am just planning / designing at the moment), and
I want to know whether I should start investigating how to do this
using django 1.0.2 or if that would be a waste of my time.

If it is going to be a while, where would you suggest I start looking
if I need to understand how to do it with django 1.0.2?

Cheers,
Em

Thanks for your help. I suspected that I would have to do this, but I

urlize

[Emily Rodgers]

Hi,

I have written a django app that manages 'change requests' (and
approvals) for IT infrastructure changes in our company, and I am
using the urlize filter when displaying certain fields (like
description of change, test plan etc). This is so that if a user puts
a link to documentation for a system / change then it shows up as a
link.

This works reasonably well - in fact too well in some cases. As you
can imagine some of the descriptions contain lists of domains, and
these are all getting changed to links. I have logged a feature
request for my next release of my app to sort the problem out
(probably by wrapping lists of domain's in  tags, then
writing a custom filter to urlize stuff that is not surrounded by
these tags), but I was wondering if this might be something that other
django users would want, and if so, is it worth me raising a feature
request to get the functionality put in to the django urlize filter?

Or perhaps someone has a better suggestion for how to get around this
problem?

RE: 500.shtml

[Emily Rodgers]

Hi Ronaldo,
 
I really think that your providers can give you more help than we can at the 
moment because they have clearly got some scripts in place to start / stop the 
webserver. I would ask them if there is an errorlog file for the webserver, and 
if not ask them if they can set one up. Trying to debug web apps without an 
error log is very tedious and wastes a lot of time.

It is not a python script, just a shell script that either runs 'python

[Emily Rodgers]

You could use the python logging module
(http://docs.python.org/lib/module-logging.html) and do
logging.debug(list(product_list)). Then it will appear in your web logs.

RE: 500.shtml

[Emily Rodgers]

How do you start / stop / restart your webserver? If you are using fastcgi,
you may not have it set up to give you an error log.

I have a script that starts / stops it, and I have specified and error log
for the django web server logs, and sent any errors with my script commands
to a file so that if it doesn't work I can see why:

python ./manage.py runfcgi [...] errlog=/path/to/weblog >> runfcgi_errors
2>&1

I am not very technical either, so I am not entirely sure, but it doesn't
sound like an OS thing, it sounds like a webserver configuration thing. If
you have used PHP with apache before it is lke doing
$_SERVER['REMOTE_USER'].

When you say "The user logs onto the server", do you mean that users point
their browser at a url and a username / password box pops up saying
something like "A user name and password are being requested by
http://blah.com.;?

If the box is set up so that you have to authenticate to view the web pages,
then I would imagine it will work. The webserver will know who the remote
user is because they have authenticated (otherwise they would not be allowed
on), so it is just a matter of accessing this, and the data will be
somewhere in the request object. It is just a matter of finding it.

I think what I did to figure out how to get the user, was something like
logging.debug(vars(request.META)) (in my view), got a couple of people in my
office a link to my webapp, and hunted around from there.

To use logging.debug you need to do this:

import logging
logging.basicConfig(
level = logging.DEBUG,
format = '%(asctime)s %(levelname)s %(message)s',
)


If you are still stuck it is worth asking the person who set up the web
server to give you more details about it, and find out how the django server
is started (and let us know).

Have you tested the suggestion above with someone who is not sshed into
the box, because if it is just the remote user of the app you want, you
really don't want to be doing '/usr/bin/ who' because that will return
the users sshed onto the box (and *not* the users logged into the web
app via your authentication system!).

I am basically doing what you are (authenticating against LDAP), and the
way you can access the remote user is request.META['AUTHENTICATE_UID'].
I am not even using the django auth.User stuff for basic web app usage
(since the user must be authenticated already, I just look to see who
they are), only for the admin stuff. Only a very small number of people
will be using the admin site so I am not to bothered about them having
to log in again (although if there is an easy way of passing credentials
across I could use that!).

HTH,
Emily

It does seem like a really odd thing to do. Are you sure you don't just
want to find out the user viewing the webapp via a browser (who has
already authenticated in a system other than django)?

RE: how to populate data again after validation

[Emily Rodgers]

It is defintely worth using django where possible to do what it can
(otherwise why use django!). The form stuff can do loads for you (validation
for one).

http://www.djangoproject.com/documentation/modelforms/

and 

http://www.djangoproject.com/documentation/models/model_forms/

Are really useful. If the input tags don't display the way you like, you can
either write your own widgets, or define a class for them and use CSS
(depending on what you want to do).

Here is a really cut down version of what you can do to get django to
display a form from a model (not very well coded but simple).
In your view...

def my_view(request)
if request.method == 'POST':
f = ContactForm(request.POST)
if f.is_valid():
f.save()
return HttpResponseRedirect('/home/')
else:
f = ContactForm()
return render_to_response('contact.html', locals())


In the contact.html template

...


{{ f.as_table }







That should get you started, but the docs are good and it is worth going
through them.

Of course you don't have to do f.as_table, you can access the fields and
display them where you like, but best to start with the basics to understand
how django works first.

RE: how to populate data again after validation

[Emily Rodgers]

Why are you using your own  tags (just out of interest!)? It might be
that you have just provided a cut down version of your code but from what I
see, there are a few reasons why it may not be working properly.

It looks like you are only passing the errors to the template, but not the
other form values. If you want the previous data, you will need to put it in
your context.

Is any validation working at all, and is it saving any data to the db? It
looks like you are calling is_valid on your POST data (not on an instance of
your form object). If you want to pass your POST data to the form, you need
to do something like this:

f = ContactForm(request.POST)

Or if you need to put more data in (or munged data):

contact_instance = Contact(att=value)
f = ContactForm(request.POST, instance=contact_instance)

RE: how to populate data again after validation

[Emily Rodgers]

Hello,

How are you doing your validation? Is the form populating a model instance
or doing something else?

I would be helpful to see some of the function in your views file.

What are you trying to do exactly? Is this to auto populate some kind of
form, or just for data integrity?

If I have a model that has a user field, and I want it to be the remote
user, I normally just set this in my view. Not sure if this is the best
thing to do but it seems to work for me.

RE: "remote models" with django?

[Emily Rodgers]

So you want it to interact with the db that app A would normally interact
with (not just copy your schema / methods)?

I don't really know how you can do that :( 

I have managed to interact with my db, via my django models in an app
installed in project 'my_proj', from an external script using:

from django.core.management import setup_environ
import my_proj.settings
setup_environ(my_proj.settings)

But I don't know who you could go about this without effecting your existing
django environment :(

Unless of course you use an external script to do your interacting with app
A, and have some kind of interface into it?

Not really sure I can be of much help...

Also, what do you mean by 'a restful model backend instead of a database

What are you trying to do? I have some ideas, but I may be barking up

RE: How to display the images in the template page under the django development server

[Emily Rodgers]

Try doing 
 

 
Ideally you want your media url to be available in all of your templates (so
you can do  in your templates).
To do this kind of thing you can set up a context processor. There is a good
example here:
http://www.b-list.org/weblog/2006/jun/14/django-tips-template-context-proces
sors/.
 
Hope this helps,
Em

Hi all
I have a lot of green in Django.When I create a app and try to show a
image in the the html ,I ran into trouble
that is the images can't be shown in the page.following is my page code:



{%block title%}{%endblock%}


My helpful timestamp site:

{%block content%}{%endblock%}

{% block footer %}

Thanks for visiting my site.
{% endblock %}






by the way,before I send this email ,I search many documents,like,someone
said following steps can help me,
http://www.djangoproject.com/documentation/static_files/

I do it step by step.but the problem still exist.

following is my configuration:

in urls.py:


from django.conf.urls.defaults import *
from mysite.view import current_time,ahead_hours
from django.conf import settings

urlpatterns = patterns('',
 (r'^time/$', current_time),

(r'^site_media/(?P.*)$', 'django.views.static.serve',
{'document_root': 'D:/test/mysite/mysite_media'}),
)

and in settings.py:

MEDIA_ROOT = "D:/test/mysite/mysite_media"
MEDIA_URL = 'http://localhost:8080/mysite_media/'



I store the CSS ,JS,and Image in the folder "mysite_media"


Is there something wrong with me?

I'd really appreciate it if you can help me.

Thanks

That is what I meant when I said ('^clients/$',

I think that you need to do  

(r'^coosci/$', include('coosci.webapp.urls')),

In your myproject/urls.py file for that to work (but I could be wrong!).

RE: problem serving image [ERROR: Page not found: /usr/lib/python2.5/site-packages/djangotrunk/django/contrib/admin/media/amazon.gif]

[Emily Rodgers]

Try changing your directory (and paths) to something like myapp_media
instead of media. Media is used by the admin interface for the css / js
files there, which is why it is getting confused.

I think you want to be looking at the python libs:
http://docs.python.org/lib/markup.html

I have used the python html parser successfully, and I assume the xml one is
similar, but it looks like you need this too: http://www.libexpat.org/

This is what I would normally have done, but I got the impression that
this kinda went again what django is about, so I was trying to do it in
a more djangoesque way!! Perhaps I will just do it how I would have
before!!

Thanks for pointing out the obvious (that I had been stupidly
disregarding) to me :)

Url tag issues

[Emily Rodgers]

Hi,

I have been hitting a brick wall so many times now on this that it is
starting to hurt!! Please help if you can...

I have an index page, and I want my function for it (in views.py) to take a
number of parameters to decide what to display, but I can't figure out how
to do it.

The kinds of options I want to give it are things like, pkid of the thing I
want to select (for more details), a filter to apply to the list of things
shown on the index page, the name of the attribute I want to sort the index
table by.

The problems I am hitting are mainly to do with the {% url
app.views.function keyword=optval %} tags to generate urls for my link bar.

The combinations or parameters I want to use are:

id
id + filter
filter
and sort_by (alone, or with any of the above combinations)

I have managed to write a regex to understand these options and my views
function does what I want, but with that regex, the {% url blah thing %}
just doesn't work at all. Do I need to just write loads of separate regexes
(for different combinations!)?

The regex that works (reading urls), but doesn't generate urls is something
along the lines of:

r'^co(|(?P\d*)/)(|/filter/(?P\w*)/)(|sort/(?P\w*)/)$
'

The kinds of url tag things I have been using are:

{% url myapp.views.index id=3 %}
{% url myapp.views.index filter_by="comp" %}
{% url myapp.views.index filter_by="comp",sort_by="date" %}

But they just evaluate to an empty string :(

The problem is the option thing. Am I just being lazy / stupid?

RE: sending data back to template out of a function

[Emily Rodgers]

Yes, but python cares about types (a lot!!). If you have {% if blah %} in
your template, the template parser will have to evaluate blah. If blah is a
string, it will evaluate true unless it is empty. I am not totally sure how
it will be evaluated if it is not a string (or a list / dict / bool), so it
is good to know what you are trying to make it evaluate.

self.location_type is a ForeignKey object (linked to your location_type
model subclass) not a string, so you either need to do
self.location_type.foo where foo is an attribute of the location_type class
with type str, or define a __str__ method of the location_type object.

If you call your phonenumber class PhoneNumber, and your location_type class
LocationType, it will help make it clearer what is an object and what is a
variable. In particular this line will be clearer:

 location_type = models.ForeignKey(LocationType)

(location_type is variable, LocationType is class name)

Hope this is not confusing (/ wrong!!).

Not sure I can :( it is not part of my signature, and gets appended to
everything coming out of the company. I will ask about though!!

The only alternative is to use an out of work email, or a google logon,
but then I have to keep checking it (which is disruptive!)

RE: forms - WTF

[Emily Rodgers]

ah. Right we need to see the view func then ;) as_table is a method of a
form class. You need to call it on an instance of the form object.
 
def myFormFunc(request):
title = 'This is My Form'
if request.method == 'POST':
foo = MyForm(request.POST) # foo is now an instance of MyForm
populated by the post data
if foo.is_valid():
foo.save()
return HttpResponseRedirect('/yourpath/')
else:
foo = MyForm()   # foo is now an instance of MyForm
return render_to_response('template.html', {'foo': foo, 'title':
title})
 
 
then in your template you can put

 {{ foo.as_table }}


does this make it clearer where foo/form comes from? It is just the
variable name you define in the context (the dict that is the second
parameter for the render_to_response function)
 
What I did (when it was only displaying my submit button and no form)
was forget to put () on MyForm().
 
Hope this helps.

PS if you need to add some (but not all) fields of a model to a form,
and then do some data munging to fill in some of the other required
fields, do shout if you get stuck - this took me a while to figure out!!

Hi Em -

I'm taking baby steps at the moment and simply don't understand
how the form.as_table works... ie when i put that in the template (see
my template below), how does it know which form to show?

RE: forms - WTF

Forms are quite confusing in django. When trying to find help on the
interweb last week I came across this that made me giggle:
http://leahculver.com/2007/04/23/django-forms-im-dumping-you/.
 
After a day or two of getting cross, I eventually stamped my feet and
insisted on having our work version of django upgraded to the lastest
SVN release so that I could use ModelForm!!

Oh, ghod, I am SO sorry :) About the ASP part, not the
switching to
Python part. You'll find Python to be a whole new
wonderful world.

'add another' popup from ModelForm?

[Emily Rodgers]

Hi,

I have been playing with Django for about a week, and I am really
impressed. I love python, but had previously been using php for my web
apps (LAMP). This is a big step forward :)

I have been having a few problems though...

I would like to use the 'add another' popup functionality (that is
automatically given to widgets for foreign key fields in the admin
interface) in my main web interface. Does anyone know of an easy way to
do this? I am currently using ModelForms to create my forms.

After a bit of snooping, I found the javascript
(django/contrib/admin/media/js/admin/RelatedObjectLookups.js) and html
(django/contrib/admin/templates/widget/foreign.html) that does it, but I
am unsure of the best way of adapting it. Is there a flag or something
that I don't know about, that I can set from within my ModelForm
subclass definition to use it already (I don't necessarily want it on
all of the foreign key dropdowns, so a flag seems like an appropriate
way)?

If not, I think my way to do it should be something like this:

Define a new widget that has the appropriate html, then add this to
urlpatterns in my app's urls.py file: 

('^([^/]+)/([^/]+)/add/$', 'django.contrib.admin.views.main.add_stage')
- not sure if this will work!!

Or

Add a similar tuple pointing to a hacked version of add_stage in my
app's views file so I don't run into permissions problems.

Am I heading in the right direction or completely barking up the wrong
tree?

Cheers,
Emily

PS

This is the version of Django I am using:
>>> django.VERSION
(0, 97, 'pre')
