this is how to do it if you are new to Django [Was: Django docs and GSoC doc summit]

[Mike Dewhirst]

I've been using the docs and haunting this list for a while and I
think I have a more-or-less new-user perspective. First of all, the
docs are great especially when compared to other stuff out there for
other kit. But if we (er, not necessarily me) are going to hack on the
docs we need an objective. There is so much there which is valuable as-
is it would be best to try for something which isn't there at the
moment.

The community benefits and the Django Foundation benefits if the
community grows. It can only grow if it is easy to get started for
newbies. Hence, I'm thinking they should be the target audience for
any new docs.

We already have the mindset that flexibility is king and that is
sufficient to draw gurus from other languages/frameworks. Now we need
a parallel mindset which says "easy" is super-cool too. I know that
all the answers for newbies are already out there for the googling but
it would be nice to say in one place "this is how to do it if you are
new to Django". So nice in fact that this could be the objective for
any new docs.

If we started with some common-ish real-world scenarios and associated
user requirements and did a standardised chapter on each scenario I
believe new users would fall in love with Django in droves.

Most gurus would hate to convert such scenarios into sets of howto
instructions because there would be too many imponderables which might
influence design and how they might do it. However, new users need to
get started and that is the sole objective proposed here.

These docs should therefore advertise a fixed, standard set of
assumptions which sit between trivial and massive in order to reduce
those imponderables and thus allow sensible, easy, non-magical, DRY
approaches to each scenario.

The last section of each scenario should be a list of suggested google
phrases or search queries to acquire more information on other
potential solutions for this and similar topics. In addition to
specific references, this means new stuff should turn up as time
passes.

The nice thing about such a set of docs is that everything has been
done properly already by someone on this list. It is just a matter of
nominating a scenario and asking for contributed solutions.

This means the docs proposed here only needs an editor pick the eyes
out of contributed solutions and minimally write them up so newbies
can understand what is happening. The entire list can technically
review each chapter.

Just a thought

Mike

Re: django-registration - stuck at Required templates topic

[Eyad Al-Sibai]

I had the same thing...

all what you need is to add " {% csrf_token %}" in each template for Post
form

it will solve your issue

Re: django-registration - stuck at Required templates topic

[bob gailer]

I have stumbled around following various pieces of advice:

added to views:
from django.core.context_processors import csrf

modified views to end with:
form = ContactForm()
c = {}
c.update(csrf(request))
c['form'] = form
return render_to_response('contact_form.html', c)

modified contact_form.html:
  {% csrf_token %}

The first bullet in the error message:
The view function uses RequestContext for the template, instead of
Context.
  makes no sense - even after attempting to read what the
RequestContext link points to.

What does it mean? Care to give an example? Like textually combining
both languages? Or does it produces both JavaScript and CSS files?

Last time I checked (today) it is a simple preprocessor, which produces
pure CSS files. It can be run statically, or dynamically in a browser.

LESS follows CSS rules, in fact any CSS is a valid LESS --- that was the
whole idea of LESS as a superset of CSS.

And could you give me a reference for my own education on "LESS is based
on older version of SCSS"?

Re: Best practice when testing form values in a template?

[Joshua Russo]

Ok, I apologize. Here is a fuller representation of what I'm doing. I had a 
hard time figuring out how much was enough versus too much. This is 
simplified, but I think it represents what I'm trying to do. For instance, 
don't pay too much attention to the save logic in the view, I haven't 
actually really worked on it much yet.

To restate my scenario, I want to carry information in hidden fields of a 
form that determine how the form is displayed and functions. I realize I do 
have access to the self.Initial values in the form itself but I don't think 
that there's easy access to those values in the template. The value that I 
want seems to be the value() method of the BoundField, but run through the 
to_python() method of the field. I actually solved this by adding a 
to_python() method to the BoundField that does just this, but I would like 
to solve this without modifying the Django code. The samples below do not 
reflect my added to_python() method.

# Form class (I use the self["multiLineInfo"] pattern instead of 
self.fields["multiLineInfo"] 
# because the former gives a BoundField which merges the Field and the 
post/initial data)
class OrganizationItemForm(ModelForm):
selected  = forms.BooleanField(required=False)  
extraRequired = forms.BooleanField(required=False, 
widget=forms.HiddenInput)
multiLineInfo = forms.BooleanField(required=False, 
widget=forms.HiddenInput)

def __init__(self, *args, **kwargs):
super(AuditModelForm, self).__init__(*args, **kwargs)
if self["multiLineInfo"].value():
self.fields["descr"].widget = 
forms.Textarea(attrs={"class":"descriptionEdit"})
else:
self.fields["descr"].widget = 
forms.TextInput(attrs={"class":"itemDescrEdit"}) 
self.fields["descr"].required = self["extraRequired"].value() and 
self["selected"].value()

Question about imports..Python Dejango and Models

[Adam Zedan]

Hi while going through the Django Book I ran into the following code
Being fairly new to Python the code kind of confused me

from django.db import models --->lineA
class Publisher(models.Model):  --->line B

Consider line A
 from django.db import models
This means that in the django directory therewill be a subdirectory of
db from in which either you'll find a file called models.py or a
directory called models??Rite?? so there is a directory called
models..great Let me know if what i said was correct.

Moving on to Line B
class Publisher(models.Model):
i am more interested in the models.Model.
does that mean in the models folder youll find a Model.py ??  I cant
seem to find Model.py then?? could anyone please clear this
concept..why cant i find this file ?? I would like to take a look at
the base class models.Model.
I have checked a couple of sites on python tutorial and they dont
cover imports in that much detail

Every contract has many products, and each product has 'rebate_pct'
and several 'wac's, so there's the intermediary ContractProduct table
that contains as many rows per contract as there are associated
products (ndcs). 'ndc' and 'wac' are foreign keys to Product and
Pricing.

"id""contract_id"   "ndc_id""wac_id""rebate_pct"
"admin_pct"
"1""1" "1" "1"  
"0.22035578""0."
"2""1"  "2""2"   "0.22035578"   
"0."

So given a 'contract_id', I am currently finding those like this:

c = Contract.objects.filter(id = contract_id)
cps = c[0].contractproduct_set.filter(contract=contract_id)

c_dict = dict(cps.values_list('ndc', 'rebate_pct'))
p_dict = dict(cps.values_list('ndc', 'wac__wac'))

for cp in cps:

  cset = Claim.objects.filter(contract = contract_id, ndc=cp.ndc_id)
  ...
  rebate = quantity * p_dict[cp.ndc_id] * c_dict[cp.ndc_id]


Is there a way to do this easier and better?

Is it possible to write a model method to access those values from
inside of 'Claim'?

Thanks.

Re: I've upgraded python from 2.5 to 2.7 do I need to reinstall django?

[Bill Freeman]

Probably.  Depends on how you installed it.

If django was installed somewhere like /usr/lib/python2.5/... then, yes, the
new python install won't have access to it.  That would be if you used
pip, eacy_install, or python setup.py as root to install it, and didn't give
any special arguments to install it elsewhere.

It's probably best to reinstall with the new python anyway, since there can
be dependencies that vary based on python version.  Note that the .pyc
files in you project are only compatible with one version.  2.7 might deal
with this for you automatically, but it is probably best to remove them and
let 2.7 build its own.

2.7, IIRC, comes with sqlite, but if you are using, say, psycopg2 or mysql,
you will probably need to install the python packages for that as well.
The underlying lib files and DB installation should be fine as they are.

You loose many things by not using the ORM. Currently I use raw() SQL
for making these kind of queries, but I would like to use the ORM for
it. Sadly, the GROUP BY support is rather limited as far as I can see.
I mostly posted this to see if anyone had any suggestions to solving
these kind of GROUP BY `problems` with the current django ORM.

I've upgraded python from 2.5 to 2.7 do I need to reinstall django?

[kierang]

Hi all couldn't find this posted apologies if its been answered.

I have just installed python 2.7, there's packages I wat to use that
are reliant on json.

I have been using Django installed in 2.5 packages on my local
machine.
To get Django now working with 2.7 do I need to install Django and the
sql lib to 2.7?
Is that the correct thing to do?


Any advice would be great

Thanks
Kieran

Re: Calculation for each object in a QuerySet

[Subhranath Chunder]

Your model declarations are very confusing for me, and seems to be running
around in circles. Very difficult to follow for me.
The logical relationships are not clear. So, how to arrive at the
'rebate_pct' and 'wac' as you actually intend, is a mystery in itself for
me.

If you have the relationships clear in your mind, then you access the
related data from a model instance like as mentioned in
https://docs.djangoproject.com/en/dev/topics/db/queries/#related-objects

Else, as suggested, you can go for raw sql queries, if the query itself is
getting too complex.

Re: splitting uploaded CSV data

[Subhranath Chunder]

Instead of writing:
f = csv.reader(open(fname, 'rb'), delimiter=',', quotechar='"')

you could have written only:
f = csv.reader(open(fname, 'rb'))

The 'delimiter' and 'quotechar' defaults to the ones you've specified.
But, it's nothing wrong to be explicit, rather than to rely on the implicit
values.

Re: splitting uploaded CSV data

[Vasu Nagalingam]

Thanks. I am on it. Info below for future readers.

What I did was:
1) set the order of the upload file handing in the settings.py so that
default behavior in Django will always be to save the file to drive
instead of keeping it in memory (for files under 2.5M)
FILE_UPLOAD_HANDLERS = (
'django.core.files.uploadhandler.TemporaryFileUploadHandler',
'django.core.files.uploadhandler.MemoryFileUploadHandler',
)

2) in my post upload routine, I opened the file using Python's CSV
manipulation library.
import csv

fname = uploaded_data_file.temporary_file_path()
f = csv.reader(open(fname, 'rb'), delimiter=',', quotechar='"')
for line in f:
   co_id = line[0]
   co_name = line[1]
   co_addr1 = line[2]
and so forth.

Re: splitting uploaded CSV data

[Subhranath Chunder]

Using the string split on CSV like this is bad in practice. Prefer using CSV
manipulation library instead. Like,
http://docs.python.org/library/csv.html

You can use the CSV reader module for your purpose.

splitting uploaded CSV data

[Vasu Nagalingam]

Hi - I am in implementing a batch file import function where the data file 
is in CSV format. The data file is uploaded (InMemoryFileHandler) 
successfully, but I am having trouble parsing the CSV data correctly.  

My code: 
for line in imported_data: 
   line = line.split(',') 

My data is organized in this 
format: , 
0001,"google","123 Main St","san francisco","CA",94000
0002,"microsoft","1 Main St, 9th Floor","Boston","MA",17000

The code works fine for the first row (google). Due to the extra comma in 
the address 1 element for Microsoft, the import of row is mucked up. Is 
there a way to indicate the text delimiter as well as data delimiter for the 
split function? Or, any other options?

Re: Count users joined ordered by month

[Subhranath Chunder]

Not the exact answer you were looking for, but I was only wondering, if you
have already figured the actual SQL query then why not simply use that
instead.

It's not mandatory to use the model query APIs, if your query is complex.
Using the raw() API would still yield you model querysets or instances.

If I was in your shoes, I'd use Claim.objects.raw() and just write a
raw SQL query (see http://django.me/raw).

Re: Django for a front end designer

[Doug Ballance]

I don't think it's necessarily a choice between learning php or
learning python.  Most programming languages are fairly similar in
concept, and once you've mastered one it's reasonably easy to pick up
a new one.  Python is a great language, but I think it's especially
great as a first language. Your time spent learning python and django
will not be wasted if you also choose to learn/use php.  I think it's
much easier to learn good methodology and practices with python, and
then carry those practices over to php than than the other way
around.

Count users joined ordered by month

[Simon Zimmermann]

In SQL we can do

SELECT MONTH(date_joined), YEAR(date_joined), COUNT(id) as
joined_month
FROM auth_user
GROUP BY MONTH(date_joined), YEAR(date_joined)
ORDER BY YEAR(date_joined), MONTH(date_joined)

Which yields a table like this

MONTH(date_joined)  YEAR(date_joined)   joined_month
3   200124
4   200186
5   2001133
6   200161

Is it possible to do this with the Django ORM? So far I only got half
of it with the following

User.objects.all().extra({'month_joined':
'month(date_joined)'}).values('month_joined').annotate(created_count=Count('id'))

Upload Multiple Images App ?

[fire_water]

I am writing my first Django application and one feature I want to
include is the ability for each registered user to be able to upload
multiple images. (By registered user, I just mean a typical "create
username/password, wait for email notice, activate account".)

Each image would be automatically resized and a thumbnail created. I
should also be able to edit and delete the image(s) in the admin.

I like the simplicity of django-stdimage but it lacks multiple image
support and has a http://code.google.com/p/django-stdimage/
issues/detail?id=22">known bug that does not delete images when
its object/row is deleted.

Photologue looks massive but according to this post, the author of Photologue recommends using django-imagekit in this
situation because it was meant to be integrated into other
applications as opposed to being a standalone application.

According to django-imagekit's github.com page, it has the same https://github.com/jdriscoll/django-imagekit/issues/16;>bug
as django-stdimage.

…ugh. Any recommendations, considering my requirements?

Thank you :)

Re: How to delete data table at command line

[Matt Mansour]

If you want to alter your schema (remove a field from the table, or
remove the entire table), first remove the field from your model, or
remove the entire model. Then make the change in your database.

Or you can look into using 'south' for schema changes. After you spend
a little time learning it you'll love it.

If you just want or remove all the data from your table, and all
foreign relations, you can use
Model.objects.all().delete()

django-admin-tools column module placement

it seems to just split the modules up into even numbers of modules per

columns so they appear at the top, as alerts. Anyone know how to do

Admin: prepolulated foreign keys in inline

[Tobias Ottenweller]

Hi,

what I'm trying to do seems to be a little hard. I've got three 
model-classes:


class A(models.Model):
...

class B(models.Model):
...

class C(models.Model):
a = models.ForeignKey(A)
b = models.ForeignKey(B)
...

class Meta:
unique_together = ('a', 'b')
...


In admin.py C is defined as a inline of B. I'm now trying to add inlines 
of C for each instance of A (that already works). Plus I want to preset 
the foreign keys to A in the inline forms & make it the only available 
choice - each inline gets it's own instance of A.

Here is want I already did in admin.py:

class CInline(admin.TabularInline):
model = C
...

def formfield_for_foreignkey(self, db_field, request, **kwargs):
if db_field.name == 'a':
a = self.as[self.a_counter]
self.a_counter = (self.a_counter + 1) % len(self.as)

kwargs["queryset"] = A.objects.filter(pk=a.id) # bad for 
performance

db_field.default = a


return super(CInline, self).formfield_for_foreignkey(db_field, 
request, **kwargs)



class BAdmin(admin.ModelAdmin):
model = B
inlines = ( CInline, )

def add_view(self, request, form_url='', extra_context=None):

inline = self.inlines[0]
inline.max_num = len(a.objects.all())
inline.extra = len(a.objects.all())

inline.language_counter = 0
inline.languages = a.objects.all()

return super(BAdmin, self).add_view(request, form_url, 
extra_context)



Problem is that formfield_for_foreign doesn't seem to be called for all 
foreign_keys in each inline element of the add page. Or maybe the 
formfield gets reused.
The result is that all inline elements get the same queryset and default 
value.


I'm a lithe bit stuck here. Maybe there is a complete other way to solve 
my problem.


Cheers

Thanks for pointing these things out about js. At least I know now that it 
isn't Django-related.

I checked the source and the relevant html and js is the same. I diffed the 
rendered js and there were no differences. Real strange though. I'll skip 
this thing and continue with some other js to see if this also gives 
problems.

Hi,

We haven't made any formal announcements about release plans for
Django 1.4 as yet.

If I had to guess, a release is still several months off. Even if we
were to cut an alpha right now, we'd still need a couple of months to
shake the bugs out, and we're not quite at the point of being able to
cut an alpha.

Re: Django for a front end designer

[bax...@gretschpages.com]

I came into Django as a designer. It can be done, just take baby
steps. The more python you learn, the happier you'll be, and the more
productive. But in the mean time, you can do a lot with generic views
and reusable apps that would keep you from having to write much code
at all. I would suggest finding Jeff Croft's Django for designers blog
post from a few years back. It's a little out of date, but still worth
reading.

Re: Django for a front end designer

[Peter Murphy]

If you are thinking about diving into PHP, I suggest you read this
first:

http://www.tbray.org/ongoing/When/200x/2006/02/17/PHP

It's five years old, but it contains a lot of links to pro- and anti-
PHP rants, which you should consider. (Consider also that there's no
good Unicode support inside PHP even after this time.) Personally,
reading it was enough for me to dive into Python instead. But you may
feel differently.

Another thing you should consider: sometimes programming languages
such as Python can be used for web-related things that aren't just
running a web server. Take screen-scraping: taking an existing website
of a client, and extracting its content for your use. There are
libraries available with Python like BeautifulSoup that allow you to
handle malformed HTML and scrape it into what ever file format you
want. Then you can use Django's admin functionality to load the file
into your database, making a new Django-powered website for your
client!

How would you screen-scrape in PHP? Is it even possible?

Before reading the Django tutorial, read the Python tutorial, and see
if the language is right for you or not:

http://docs.python.org/tutorial/

Whatever your decision, good luck!

Best regards,
Peter

Here is the roadmap wiki:
https://code.djangoproject.com/wiki/Version1.4Roadmap

Which is pretty empty, but you can sort the tickets by milestone and
get an overview:
https://code.djangoproject.com/query?milestone=1.4=id=summary=status=owner=type=milestone=priority

Also, 1.2 was released May 17th 2010
1.3 was released March 23rd 2011 ... so almost a year (although that
may not happen 1.3 -> 1.4)

Django doesn't "block" javascript, and is totally agnostic about
javascript FWIW.

> I've tried the {% autoescape on/off %} tag,

Escaping considerations only apply to dynamic content (=> content
inserted by the template system using either a {{ var }} or a {% tag
%}). See the "safe" (IIRC) filter to disable escaping on dynamic
content.

There's nothing to "activate".

Basically, unless you inserted your js code (or any other markup)
using a {{ var }} or {% tag %}, there is NO "restrictions on these
blocks with javascript".

Did you at least inspected the *rendered* template to see how what
your HTML and js looks like ?

Re: Start to get error after modifying models

[Shawn Milochik]

What did you change? Hopefully you're using version control and can do a 
diff.


The traceback you provided isn't very helpful to most people because 
it's from Django's internals instead of your own code.


In any case, you need to do more work before you'll get much help, 
unless someone's specifically seen this traceback before and solved it 
and feels super helpful.

Re: Run an application periodically on django

[sedl...@gmail.com]

Hi,
just one thought - if the update is not much time-consuming, you can
write your view which allways parses the data and then cache the view
for 30 seconds. That way if nobody looks at your page, you won't do
useless work in the background.

See https://docs.djangoproject.com/en/dev/topics/cache/

Filip

onmouseover in JavaScript not working

[Josh]

I'm new at Django and am experimenting with JavaScript in templates. 

I've put JavaScript from Google Charts in a block and it is displaying the 
chart properly. The onmouseover should display the details of elements in 
the chart, but that isn't working in Django. In a plain html-page it is 
displayed, so I guess it is being blocked by Django and I should enable 
this.

I've tried the {% autoescape on/off %} tag, but that doesn't solve it. How 
can I activate this? Basically I want no restrictions on these blocks with 
JavaScript.

Programming by accident won't get you very far. You should either
contact the original developper or, if not possible, find out which of
the django apps is responsible for the menus (looks like some django-
cms stuff but I may be wrong) and read the doc if any. If by then you
still havent found out, try asking on the app's newsgroup (if any), or
go and read the source code until you understand enough of it to solve
your problem.

Django - modifying navigation design

[Daniel]

Hi,

I'm working on a Django website made by someone else and I'm trying to
change how the navigation on the left looks.

Currently it shows links to pages on the current level and any child
pages, but we're looking to have it more traditional where it shows
parent and child pages (to a certain extent).
For example from the homepage you can go to Products and Products has
child pages and those child pages may have child pages etc.

If you go into Home>Products>Transportation>Flight on the left hand
side we want it to show:

 - Products
  - Transportation
 - Flight
 - Driving
  - Engineering
 - Blah


Instead it currently shows:

- Transportation
- Flight
- Driving
- Engineering
- Blah

I've tried looking into Django Administration for any way of editing
it but the best i can come up with is if I go into the Menus link it
shows an added menu called 'Left Menu' which when clicked on doesn't
give you anything really to change.

Otherwise in the ftp server I've gone into themes and found the
template html file which has amonst other things:

{% show_menu "left_menu" "leftmenuinner" "parent" 0 100 0 1 %}

If I try modifying the four parameters (start_level, end_level, etc.)
nothing happens (even removing them completely doesn't change
anything).

Removing "parent" makes it just show the initial page links (Products,
About Us, etc).
Removing "leftmenuinner" removes the css from the links.
Of course removing "left_menu" makes it so no links appear as they're
all connected to that menu name.

Would anyone know where I should go to modify how it the links show up?

Without more informations about your models (and specially the
relationships), it's going to be rather difficult. As a general
consideration, if your Claim model can access these other models thru
relationships, well you just have to follow the relationships. This is
basic Django ORM stuff, well explained in the FineManual.

Google AppEngine vs. dedicated hosting (Pros/cons)

[Herman Schistad]

Hello.

I'm developing a site with approx. 500 visits per day, mainly from
Norway (Europe).

Now I'm trying to find the best possible way to host this site.
Earlier I've used dedicated hosts like WebFaction and Djangoeurope,
and this has worked pretty well.
However Google AppEnginge is free and provides a really reliable
server (as far as I can tell). But I'm no expert on this matter and
therefore come to you guys.

What is the tradeoff between using Google AppEngine (with
django-nonrel [1]), learning this, and writing my application for the
Google datastore versus using a traditional host.
Are there any big challanges by using AppEngine?

A third alternative would to maybe invest in e.g. dedicated virtual
machine at MediaTemple[2] or something.

So what it all boils down to: which is your preffered hosting method,
and why/why not?
- Google AppEngine
- Dedicated django hosting (e.g. WebFaction[3])
- Virtual server/dedicated server (e.g. MediaTemple)

tl;dr: pros/cons with Google AppEngine, and which hosting method is
your preferred method?

hi,

I am new to the Django list but I am a django fan (we dev with Django

(details below):

You can apply as an individual or a group.  Applications close Friday
(5th), application process takes about 2-5 mins :)


Hi Adam,

Thanks for drawing our attention to this. This sounds like a great
opportunity to hack on Django's docs -- I'll see if we can shake loose
some volunteers to attend.

For anyone

Yours,

Re: django-registration - stuck at Required templates topic

[Bruce Dou]

I also think that should be a default simple template in the package.
