Help needed in setting up User Auth JWT system

[K Surya Kumar]

Hi Team,
The question is not much detailed but straightforward. I am looking for the 
best way to implement JWT authentication using Django.

I'm currently developing an application. Where I have to authenticate the 
users using a JWT token also one user may create multiple token (Mobile App 
and Web App).

Can you please guide me with any available auth package for Django or the 
best way to implement the same?

You need to be more specific. It should be simple enough to create a 
self-extracting archive, but I doubt that's what you mean or is it?


Kind regards,

Re: Async Help Needed

[Andrew Godwin]

The example you presented should Just Work - that error generally only occurs 
if you return an un-awaited coroutine, which if you're just returning a 
response, should be impossible.

What version of Python and Django are you running?

Async Help Needed

[Steven Mapes]

Does anyone have some links to good guides on getting asnyc to work with 
Django? I have a use case where I really need to have a view give an async 
response but I can't get even the most basic of examples working.

I've tried the examples from https://testdriven.io/blog/django-async-views/ 
with a simple view of:

async def test_view(request):
return HttpResponse("Hello, async Django!")

I've installed uvicorn and am running it with  uvicorn 
my_project.asgi:application --reload

My sync views work as expected but the async one just returns an error of "*The 
view sample.views.test_view didn't return an HttpResponse object. It 
returned an unawaited coroutine instead. You may need to add an 'await' 
into your view.*"

Re: Help needed

[Rodrigo Delfino]

Such as others have said, you should remove ```auto_now=True```, after 
that, you cant  forget to run ```makemigrantions``` and ```migrate```

Why don't you change field type to Char and save the datetimestamp by your

Re: Help needed

[John]

I think you are misunderstanding the use of `auto_now=True`. It will 
always set that field to the time when the object was last saved; it's 
not meant to be a form field. See 
https://docs.djangoproject.com/en/3.1/ref/models/fields/#datefield. What 
are you trying to do? Have a date field that is preset to today's date? 
If it's that, then the next paragraph in the docs explains how to set 
`default=`.

How to Run script on remote server from Django Webserver - Help needed

[Sharanagouda Biradar]

Hello All,

I have started learning Django last one week and able to fairly understand 
basic poll application in tutorial, Now I need any of your help in meeting 
my requirements:

*Requirement below :*

I have a basic (server1) Django development web server and another server 
(server2) which has a python script that will launch local application. 
Assume that the server1 has necessary authentication in place to run the 
script on server2. All I want to do is, click a button on the django 
website which would run the python script sitting on server2. Apart from 
above I need to get status of tests running as part of server2 application, 
along with csv files from Server2 back to server1 (web server).

Can I achieve the above requirement using Django REST APIs? or Django 
Remote submission ? I am really clueless here, any pointers are highly 
appreciated.

Re: urgent help needed with my rest

[Andréas Kühne]

Hi,

The problem you are having is that the ID you are sending to your
deleteTask angular method is undefined - that's what the log shows. Check
the angular code to see why you are not sending a valid id to the
deleteTask method. This has nothing to do with the rest api - it is
functioning perfectly - the issue is that the rest api can't find the task
with id of "undefined" - and "undefined" is what you get when you use a
javascript variable before it's declared.

Regards,

Andréas

You need to include the CSRF token immediately after the form action

    
    {% csrf_token %}

... so if that occurs in card2.htm that's where it should be.

You named your list 'MyListArg' not 'mylist' in the dictionary you 
passed to the render function.


Try changing this:

{% for val in mylist %}

To:

{% for val in MyListArg %}

That should hopefully fix it. I haven't tested it though.

Master-Detail Form help needed

[jon]

I have been struggling mightily with Master-Detail forms in Django. I have 
done a number of online tutorials but have yet to find a complete tutorial 
which completely explains models, views, templates, URL patterns related to 
master-detail forms. I use the Oracle toolsets where creating a 
master-detail form is just a matter of feeding the template your master 
table (model) and then selecting your detail table (model). It generates a 
basic form for you with CRUD controls. Similar to how the Django admin tool 
works.  If someone could point me toward a good comprehensive book chapter 
or tutorial, I would be much appreciated. TIA.

Re: Help Needed: Django Server For High Frequent Requests

[Avraham Serour]

don't use runserver for production ever.

read the django documentation:
https://docs.djangoproject.com/en/1.10/howto/deployment/

after that I suggest using nginx with uwsgi

it is also worth reading uwsgi documentation, there are a lot of options
you can tweak

nginx also has some options you can tweak

Help Needed: Django Server For High Frequent Requests

[Xiao Bo]

I'm building a Django server for data collection. However, the program 
seems not capable when the sensing network expands. As time goes on, the 
program doesn't even enter the code piece and report broken pipe/connection 
reset by peer/too many open files errors:

Oracle DB, some help needed

[Jani Tiainen]

Hi everyone,

I'm currently trying to maintain Oracle backends for Django and found
interesting issue that I would like Oracle users to run in their databases.

(I'm not sure can you run these in XE, you may try but I think these
require full Oracle)

Two SQL clauses that I would like you to run are located in my gist <
https://gist.github.com/jtiai/e3459777debf97458187>

Pay special attention to srsName value returned from queries, then please,
post your results and Oracle version your database is running.

If you don't want to post your results in public, private mail is
acceptable.

Thank you for your co-operation.

Re: Help needed for big django project (crm+shop+cms+autoresponder). What apps shall I build on?

I know this is an old thread, but I bumped on it while cleaning my inbox.

In any case if it still relevant I recommend looking at treee.io, the
website is down but you can take a look at the code at github (

If you need to create addicional software or library then we (my company)
could offer you commercial support or we could be your partner.
Contact me privately (see my email in the email header) and talk me about

Re: Help needed for big django project (crm+shop+cms+autoresponder). What apps shall I build on?

[Luis Zárate]

Did you serch for something like this https://www.*odoo*.com/, It is not
django but it is in python and  released under the AGPL license.

If you want to build your software stack based in django then start
searching in https://www.djangopackages.com/.


1. *CRM* system
 -> client database
 -> ticket system (client communication including sending emails from
backend)


 2. *Shop*
 -> calender booking system
 -> PDF billing generation
https://github.com/burke-software/django-report-builder

 3. email *autoresponder* system
 4. *CMS* functionality would also help


django-oscar is interesting software, take a look at
https://github.com/django-oscar/django-oscar

Help needed for big django project (crm+shop+cms+autoresponder). What apps shall I build on?

[ThomasTheDjangoFan]

Hi guys,

I am planning on a bigger django project with a lot of functionality.

The thing is that I have NO experience with existing django-apps that might 
fit and definetly need your help.

Can you give me a hint which existing (and stable) django-apps I could use 
as a foundation for my project?

Those are the functions that I would like to implement (ordered by priority)
 1. *CRM* system
 -> client database
 -> ticket system (client communication including sending emails from 
backend)
 2. *Shop*
 -> calender booking system
 -> PDF billing generation
 3. email *autoresponder* system
 4. *CMS* functionality would also help

I would be really thankful if you could guide me to the right direction.
Which way shall I go?

Kind regards
Thomas

Re: Help needed in constructing __in query

Help needed in constructing __in query

[Subodh Nijsure]

I have two tables as shown below.

class AlertTable(models.Model):
id = models.AutoField(primary_key=True)
alarm_text = models.CharField(max_length=800,blank=False,null=False)
event_type = models.SmallIntegerField(blank=False,null=False)
created = models.DateTimeField()
class Meta:
ordering = ['-id']
def __unicode__(self):
return str(self.id)

class PendingAlertsTable(models.Model):
id = models.AutoField(primary_key=True)
alerttable = models.ForeignKey(AlertTable)
created = models.DateTimeField()
class Meta:
ordering = ['-id']
def __unicode__(self):
return str(self.id)

Idea is PendingAlertsTable holds reference to alerts that have not
been acknowledged. And AlertTable holds all the alerts.

So I want to construct query such that I can get all entries from
AlertTable that are Pending.

So I constructed query like this:

inner_qs=PendingAlertsTable.objects.all()
all_pending_events = AlertTable.objects.filter(pk__in=inner_qs)

That doesn't give me query set in all_pending_event of expected
entries. What is the correct way to construct the __in query in this
case?

Re: virtualenv help needed

[Lachlan Musicman]

Two things:

1. Put your media local to your site - I use
/home/user/www/dj-project/static and
/home/user/www/dj-project/collected_media for project at
/home/user/www/dj-project/

2. The place you are referring to is inside the virtual env's little
jail. You can find that by using the cdsitepackages command when in
the venv. But you shouldn't really put your data in there. The Two
Scoops of Django book has a good example of choices available and then
good reasoning for the style they recommend. It's worth the read.

The idea is that a beautiful image is frameable. Everything you need
to see is there: It’s everything you want, and it’s very pleasing
because there’s no extra information that you don’t get to see.
Everything’s in a nice package for you. But sublime art is
unframeable: It’s an image or idea that implies that there’s a bigger
image or idea that you can’t see: You’re only getting to look at a
fraction of it, and in that way it’s both beautiful and scary, because
it’s reminding you that there’s more that you don’t have access to.
It’s now sort of left the piece itself and it’s become your own
invention, so it’s personal as well as being scary as well as being
beautiful, which is what I really like about art like that.

Why are you placing user media in your /usr/local/.../dist-package

Wouldn't it make more sense to place them somewhere in /srv or /var?

Help needed with Django Slug Url Caveat

[JJ Zolper]

Hello fellow Django developers,

I would like to request your assistance on a caveat I ran into when doing 
slugs in the django url's.

First off please let me lay out what I've been building:

Here are the internals of my urls.py:

(r'^artists/register/$', 'madtrak.userprofiles.views.ArtistRegistration'
),

(r'^artists/login/$', 'madtrak.userprofiles.views.ArtistLoginRequest'),

(r'^artists/logout/$', 'madtrak.userprofiles.views.ArtistLogoutRequest'
),

(r'^artists/(?P[a-zA-Z0-9]+)/$', 
'madtrak.userprofiles.views.ArtistProfile'), 


Here are some relevant views.py functions:


# Artist Profile

def ArtistProfile(request, artistreq):

artist_object = Artist.objects.filter(artisturl = artistreq)

return render_to_response('artistprofile.html', {'Artist': 
artist_object}, context_instance = RequestContext(request))


and


# Artist Registration

def ArtistRegistration(request):

if request.user.is_authenticated():

return HttpResponseRedirect('/artists/profile')

if request.method == 'POST':

form = ArtistRegistrationForm(request.POST)

if form.is_valid():

# If information entered is valid create the user  

# user = User.objects.create_user('john', 
'len...@thebeatles.com', 'johnpassword')

artistusername = form.cleaned_data['artistusername']

artistemail = form.cleaned_data['artistemail']

artistpassword = form.cleaned_data['artistpassword']

artistuser = User.objects.create_user(username=artistusername, 
email=artistemail, password=artistpassword)

# Save new user to the database

artistuser.save()

artist = Artist(artistuser=artistuser, 
artistname=form.cleaned_data['artistname'], 
artistbirthday=form.cleaned_data['artistbirthday'], 
artisturl=form.cleaned_data['artisturl'])

artist.save()

return HttpResponseRedirect('/artists/profile/')

else:

return render_to_response('registerartist.html', {'form': 
form}, context_instance=RequestContext(request))

else:

''' user is not submitting the form, show the blank registration 
form '''

form = ArtistRegistrationForm()

context = {'form': form}

return render_to_response('registerartist.html', context, 
context_instance = RequestContext(request))


So, basically here is the caveat: If a user requests artists/register the 
site goes to hell. Why? well it's because as you might have guessed that 
request also fits the regex expression listed where I url config'd (r
'^artists/(?P[a-zA-Z0-9]+)/$', 
'madtrak.userprofiles.views.ArtistProfile'), 

and so the url config does not behave as I desired. Or if I requested 
likewise if you put artists/ [artistuser] it collides still with the rest 
of the url configs. So, my quick fix and was:


(r'^artists/register/$', 'madtrak.userprofiles.views.ArtistRegistration'
),

(r'^artists/login/$', 'madtrak.userprofiles.views.ArtistLoginRequest'),

(r'^artists/logout/$', 'madtrak.userprofiles.views.ArtistLogoutRequest'
),

(r'^artists/profile/(?P[a-zA-Z0-9]+)/$', 
'madtrak.userprofiles.views.ArtistProfile'), 


which thereby says hey if I only see artists/profile/ and then the 
requested artists profile then I behave as desired and return that artists 
public profile. Which makes sure it is obviously not listening at just 
artists/ [anything else]

Yet the thing is I REALLY want to be able to have it is I originally had 
it. I like how clean it is. I strongly desire the situation where I can 
host all the registration, login, logout, and any other systems that I 
desire following the artists/ but also want to be able to also cleanly host 
all artists usernames following the artists/ so that it properly querys the 
db and returns that artists profile.

I was thinking maybe I could hack this out with python regex or something 
of the like but is there a way in django to hack this together?

Thanks so much,

JJ

Re: Little help needed writing models for star-ratings app

[Shawn Milochik]

I reiterate: Please read the ORM documentation. That will answer all of
your questions. Once you understand how to do queries in the ORM (and which
queries are easier than others) then you will know how to design your
models so that they'll be easy to work with. As you're reading, make notes
about how you can aggregate and search across tables/models.

I am not sure but.. my concern is more about "relationships"

How should I be defining Rating model for

counting number of specific ratings it got
user who rated it.. 

probably, to log the user data

user = models.ForeignKey(User) would work

But counting number of specific ratings it got is the issue!!

Say there is a Book X. Its ratings are by default 0, 0
Now, as the users add ratings, its get added up to the default and its 
fine.. 

but how to know who added what ratings? and how many times he changed etc..

would a ManyToMany field with User and Rating would work?

Re: Little help needed writing models for star-ratings app

It looks like you're not looking for a "little help." You're looking for
someone to do the work for you.

You'll get the best help if you try something, get stuck, and explain what
you tried and what the error is.

Here is the documentation for using the ORM. This is not a snarky response
-- I really hope you do read it and learn how to use Django's ORM, which is
what you need to answer your own questions.

https://docs.djangoproject.com/en/1.5/ref/models/querysets/

Read that, try some stuff, then ask specific questions when you have
problems. You'll get a lot of great help if you do that.

Little help needed writing models for star-ratings app

[surya]

Here is the story so far

class Rating(models.Model):
positive_rating = models.FloatField(default=0)
negative_rating = models.FloatField(default=0)

class Book(models.Model):
year_pub = models.IntegerField(max_length=4)
category = models.ForeignKey(Category)
rating = models.ForeignKey(Rating)
hash_id = models.CharField(max_length=64, null=True, blank=True)

There are few books. Each will be having 2 types of rating. +ve one and -ve 
one, 
The rating is done using "stars". If +ve rating is done, -ve field will be 
0 vice versa.

votes could be simple stored in this way

o = Book.objects.get(pk=1)
o.rating.positive_rating += 2.5
o.rating.save()

Here comes the actual trouble -->

1. How to count the number of ratings
2. How to know which user has voted
3. How to know whether the user has previously voted or not

Typically, how to attach this MyUser (example) model to the Rating Model?

Thanks

dict(zip([col[0] for col in desc], row))
for row in cursor.fetchall()
]

My issue is that I cannot figure out how to populate a Table2 table with 
this info.  Table2 suggests 
this a way to achieve my goal, but I can't figure it out. 

import django_tables2 as tables
data = [
{"name": "Bradley"},
{"name": "Stevie"},]
class NameTable(tables.Table):
name = tables.Column()
table = NameTable(data)


Your help would be much appreciated.  Thanks.

Correct. So when you are creating a new UserProfilePic object, you
will need to populate those fields manually. I know of a couple of
techniques:

1) Do it manually:

frm = UserProfilePicForm(request.POST, instance=None)
if frm.is_valid():
  instance = frm.save(commit=False)
  instance.userprofile = user.get_profile()
  instance.save()

2) Pass the profile to the form's constructor, override the save
method and implement the same logic there:
class UserProfilePicForm(ModelForm):
  def __init__(self, *args, **kwargs):
self.profile = kwargs.pop('profile')
  def save(self, commit=True, *args, **kwargs):
instance = super(UserProfilePicForm, self).save(commit=False,
*args, **kwargs)
instance.userprofile = self.profile
if commit:
  instance.save()
return instance
  class Meta:
model = UserProfilePic
fields = ('profilepic',)


>also,

Probably. You don't want multiple profiles linking to the same picture
do you? IE each picture has exactly one owner.

Re: help needed with multiple profile images with UserProfile

Hi Tom,

Thanks for your reply. So for clarity i thought i was getting the
userprofile to pass into the bound form so that the userprofile_id in
the UserProfilePic would get populated/saved. as if i leave the
instance as None
then i get an error saying that userprofile_id cannot be empty? also,
is a 1 to may relationship here correct for what i want to achieve?

u.get_profile() returns a UserProfile. Your form definition says that
this form is for a UserProfilePic model.

help needed with multiple profile images with UserProfile

[richard]

Hi, Am i doing this in the correct way? I am trying to accomplish a
UserProfile having multiple profile images. IE if a user uploads a
profile photo it gets saved as the default profile pic but if they
upload another pic then that becomes the default pic but i need to
keep records of all the profile pics that user has uploaded so that if
they view there profile pics they can see them all. Is this  1 to many
on UserProfile or a ManyToMany? as when i try a 1 to many i cant seem
to get the code working.

any help would be greatly appreciated.


code below.

MODELS.py
from django.contrib.auth.models import User

class UserProfile(models.Model):
user = models.OneToOneField(User)

class UserProfilePic(models.Model):
userprofile = models.ForeignKey(UserProfile)
profilepic = models.ImageField(upload_to='photos')

FORMS.py
from .models import UserProfilePic
class UserProfilePicForm(ModelForm):
class Meta:
model = UserProfilePic
fields = ('profilepic',)

VIEWS.py
def userprofilepic(request):
c = {}
c.update(csrf(request))

u = User.objects.get(pk=1) #just testing with 1 user
form = UserProfilePicForm(instance=u.get_profile())
if request.method == "POST":
form =
UserProfilePicForm(request.POST,request.FILES,instance=u.get_profile())
if form.is_valid():
form.save()
else:
return HttpResponse('failed')
c['form'] = form
return
render_to_response('photo.html',c,context_instance=RequestContext(request))

SQL OUTPUT thats been run on the view which doesnt seem to update
userprofilepic table

{'time': '0.001', 'sql': u'SELECT "auth_user"."id",
"auth_user"."username", "auth_user"."first_name",

RE: form select box how to (help needed)

[Chris Matthews]

Hi Bobby,

See 
http://adil.2scomplement.com/2008/05/django-add-choices-to-form-fields-on-runtime/

Try something like the following:

# Define your choices
LOCATION_CHOICES = ((1,'location1'),
(2,'location2'),
(3,'location3'),
(4,'location4'),
   )

LOCATION_CHOICES_PUBLIC = ((1,'location1'),
(2,'location2'),
(3,'location3'),
   )

Example 1
-
class ProfileForm(forms.Form):
class Meta:
model = Profile

locations = forms.ChoiceField(required=True)

def __init__(self, *args, **kwargs):
# This is a bit of a hack
if 'user_type' in kwargs and kwargs['user_type'] == 'public':
public = True
# We do not want to pass our kwarg to super
del kwargs['user_type']
else:
public = False

super(ProfileForm, self).__init__(*args, **kwargs)

if 'user_type' in kwargs and kwargs['user_type'] == 'public':
self.fields['locations'].choices = LOCATION_CHOICES_PUBLIC
else:
self.fields['locations'].choices = LOCATION_CHOICES

In your module use
form = ProfileForm(user_type='public')
or
form = ProfileForm()

Example 2
-
class ProfileForm(forms.Form):
class Meta:
model = Profile

# the limited choices are our default
locations = forms.ChoiceField(choices = LOCATION_CHOICES_PUBLIC, 
required=True)

In your module
form = ProfileForm()
if not public:
form.fields['locations'].choices = LOCATION_CHOICES


Example 2 is a bit 'cleaner'/neater I think.

Regards
Chris

form select box how to (help needed)

[Bobby Roberts]

I've got several select boxes in a user profile that the we can
manipulate in /admin.  One of these select boxes is called "locations"
and has locations to which you can assign a user.

for explanation, let's say that that the select box is populated like
such:


1,location1
2,location2
3,location3
4,location4

where the numbers are the option values and the text is the option
text.

In this user profile, if they choose ocation1,location2,location3, it
saves to a session variable as "1,2,3" (and of course also saves in
their profile.)

so far so good.


now here's what i need help with.

On the public side of the site, they'll login and do certain things.
i want to have a select box (as previously described), HOWEVER, i only
want it populated with options 1,2 and 3 (the values in their session
variable)... not the 4th location since they haven't been assigned to
that location.


I can't load it through the "CHOICES" parameter in my forms field...
how can I do this?

I agree when it comes to a gui based environment. When developing with django, 
a gui is really not necessary. You can start the vm and treat it as a remote 
server and log in via ssh and do your work that way. It runs 100% better or 
just run a 'local' terminal for the vm and work that way.  

VM's used this way are great for emulating your production environment (most 
configuration and settings) and on a 3-4gb system you can have 3-4 vm's 
running concurrently for testing using multiple servers (i.e. db, static 
media, and your django install) having a smaller (compared to production) but 
more complex setup that you can find in a lot of situations.

And, as was pointed out on the last thread on this topic, this isn't a
Linux support group.

At the moment, none of your problems appear to be related to Django --
they are to do with using your chosen operating system. Django's
tutorial isn't going to provide *any* assistance on why your Debian
install won't boot into a virtualbox on Windows.

You'll have a lot more luck getting an answer if you direct your
queries to an appropriate forum, such as a Debian users list.

Why don't you try partitioning your hard drive instead and doing a dual boot

Expert help needed --LINUX on virtualBox using Windows 7 machine

[Kimberly]

This is now a LINUX-Derbian problem I am experiencing. I open the
virtualbox and clicked on the Linux-Windows that I wanted, and clicked
on "start" to run it. Once it run, it is black screen. I already mount
the Derbian iso to the program, so I am lost for words on what is
going on. This is a struggle and I am frustrated because I just don't

Revisioning and fullhistory help needed

[Tanis]

I have an app that contains an Item model. I want to track changes to
this model so that I can see that on day X item looked like this and
on day Y it looked like that.

Since fullhistory seemed to be the most recently updated module for
this, I decided to go with that. However, it doesn't seem to have
actually done much of anything and I don't really know what
functionality it will give me anyway.

I followed the install instructions line for line, but can see no
changes to the admin interface. The history for an Item looks
identical to as it was before.

What should have changed? How do I view the full history? Will this
actually do what I want it to do?

Re: HELP NEEDED

[Michael Sprayberry]

I would definitely go Django for this project and maybe divide out the project 
and get some people to help you seeing as this is your first project. Not only 
do you have to take into account the look up the website, the models for 
employers and freelancers, but you are also going to need to take into acount a 
Link to get these emails sent to the freelancers and also the replys to the 
employers and assumming you don't want to be giving out personal information 
this requires some allisoning. 
 
Good luck to you on this project and if you want help get back to me.

Hi,
I have done some extensive reading on python.
i want to design a classifieds site for jobs.
The service is meant to send people who register an sms with available jobs 
that fit their criteria/cv.
But the main idea is that people come and register for quick jobs(like 
www.freelancer.com) and put up their 
criteria,age,location,qualificationsand when a company or employer posts a 
job,the people that fall into the category that was specified get sms and email 
alerts as to the availability of the job.
I am taking this as my first project and would appreciate any help.
I am looking in the direction of python, maybe django.
Thanks.

RE: Field Subclassing, or setter help needed.

[Sells, Fred]

But the input is valid in the legacy system from which it comes; it is
just Not Applicable for the database record into which it would be
inserted, based on other parameters in the db.  These are two totally
separate systems, and we want to use the legacy data in some cases to
keep reports in sync.

Input validation should be done at the point where you handle input,
that is in the forms you use for updating instances.

Field Subclassing, or setter help needed.

[Sells, Fred]

I need to override the setter behavior of all the fields in all my
models.  They all subclass from the same abstract model.

Specifically if the fields already contains a special character (used to
indicate "Not Applicable") I don' want to allow it to be changed.  The
same field will be applicable in some types of records but not in
others.  The updates come from an external backend http query that I use
to get data from a legacy system. That legacy system does not know if a
field is applicable or not.

I've got about 25 tables and a total of 500 fields.  I would like to
build this feature into the abstract model and not have to not have
custome code for each field update..

I would like to override the "setter" method in my abstract model, but
cannot seem to get that to work, tried numerous variants.  I am a Django
newbie, but I've spent a day with the docs, books and google with no
success.

Can someone point me to a snippet or a coherent example/explanation on
how to do this.  I'm using Django 1.2 with Python 2.4.

Thanks,

Fred Sells

Re: Urgent Help Needed On Python/Django ModelChoiceFields

[Bill Freeman]

Well, where are things happening?  Do you make a new request for each
click, or do you want the changes to appear without a browser reload?

If the former, the ability to customize seems to imply a model representing
a choice, with a foreign key on the same model, allowing it to specify of
which choice it is a sub choice, giving you a blah_set queryset.  It can
contain whatever additional info you need, obviously.  Then the buttons
can be submit buttons of the form with the select representing the choice,
with various values, so you know which button, and the view will interpret
the buttons in the context of the selected choice.  That is, look up the
choice which contains info about what to do for each button.

If the latter, that's a bunch of javascript, and yes, you need to manage
the connections somewhere, but you don't want to be doing many DB
queries every time you load the page, so you probably want to cache
the tree, probably in a class variable (in RAM) on startup and whenever
the configuration is changed (via a custom form which you must be staff,
or whatever to view and submit, not part of the admin app).

Or I may still be completely misunderstanding your problem.

Re: Urgent Help Needed On Python/Django ModelChoiceFields

[pedjk]

Thanks Bill. I'll clarify.

Basically what I want to do is give each option under the choice field
a function. So once the user has selected an option under the drop
down box, that would initiate a script which would generate a set of
links (buttons) at the bottom of the page to take the user to the next
step.

So if under the drop down menu you choose "Done", that would
automatically generate two links. One that says "Stop" and one that
says "Close". What the links do isn't important, it's how to get the
chosen option to generate the links that I don't know how to do.

Someone mentioned to me to use a state table. I'm not sure what that
means, but maybe others do.

Now the reason I bring up the admin page is because I also want it to
be customizable from there. So as an example, if selecting "Done"
generates a "Stop" and a "Close" button, I might want to change those
button and or their links at a later time, and I would want to do it
from the admin page.

Hopefully that clarifies things more and thanks again

Re: Urgent Help Needed On Python/Django ModelChoiceFields

[Bill Freeman]

Since it's urgent, I'll give an opinion despite not fully understanding your
description of the problem.

If it's going to be so far removed from what the admin app does by
default, I'd go with a custom view outside of the admin, which you
can customize to your heart's content.

That is, when it's really hard to fit something in an existing box, you
should probably build a different box.

Urgent Help Needed On Python/Django ModelChoiceFields

[pedjk]

Ok, I'm quite new to Python and Django so this might actually have a
simple solution.

I'm coding for a form using Django and I have a ModelChoiceField. Now
what I want to do is make the options for this field customizable. So
if you choose an option, a set of links would be generated allowing
you to move to the next step.

All I know is that this should show up on the admin page for Django,
and it might require a state table or some sort of back coding from
mysql.

If anyone could help, this is quite urgent.

one way is to override __init__. Here is a sample:
class Accountaddform(ModelForm):
def __init__(self,head,*args,**kwargs):
super (Accountaddform,self).__init__(*args,**kwargs)
self.head = head
self.fields['head'].queryset=Account.objects.filter(pk=self.head)
class Meta:
model = Account

Nothing to do with __unicode__. You want limit_choices_to.

help needed in ModelForm __unicode__

[Emanuel]

Hi!

I Have this model:
class Person(models.Model):
user = models.ForeignKey(User)
nr = models.IntegerField(blank=True,)
gender = models.CharField(max_length=1, blank=True, 
choices=gender_choices)


def __unicode__(self):
return self.user.get_full_name()


I'm using a modelForm of this form.

I have another model:
class Couple(models.Model):
season = models.ForeignKey(season)
man = models.ForeignKey(Person, related_name='man',)
woman = models.ForeignKey(Person, related_name='woman',)


And I'm also using a modelForm of this one.

In the template I  have a combobox for the man and for the woman wich shows 
the __unicode__ method of Person model, but it shows both women and men in 
both combo's.
I want to filter only men or women depending the case. Is it possible? Or 
should I create another method for independent cases? If it is the solution 
how can I use it? I'm not getting there because it is a instance of a class...

Desperate Help needed. manage.py runserver no longer works.

[CrabbyPete]

I am new to django and I am running it on a Windows server. I
installed mod_wsgi with Apache and go it to work, but now when I run
python manage.py runserver. I get the error

Error: Could not import settings 'spot.settings' (Is it on sys.path?
Does it have syntax errors?): No module named settings
Exit code:  1

mysite is call spot. Can anyone tell me why running the django server
no longer works. I am going nuts trying to figure this out, and before
I rip out everything and start over can some please give me some
advise what to look for and what I might have gone wrong. I can only
assume it has something to do with what I did in my spot.wsgi file

import os
import sys

sys.stdout = sys.stderr

from os.path import abspath, dirname, join

The MEDIA_URL variable will only be populated in your template if the
template is passed a RequestContext instance as the context (not just a
Context, because you want the context processors to be executed) *and*
is you have the "media" context processor in your
TEMPLATE_CONTEXT_PROCESSORS list (which it will be by default).

I would suspect you've forgotten to pass a RequestContext to
render_to_response() or whatever call you're using in your view.

help needed: apache httpd.conf and urls

[zayatzz]

Hello

I have this in my template :


settings file is following:
MEDIA_ROOT = '/var/www/media/'
MEDIA_URL = "http://localhost/media/;

when i go to the webpage then the stuff that i get from server says


Even when i replace {{ MEDIA_URL }} with anything else i still get
this in browser:


Why?

Just in case you need my httpd.conf:


SetHandler python-program
PythonHandler django.core.handlers.modpython
SetEnv DJANGO_SETTINGS_MODULE mce.settings
PythonOption django.root /mce
PythonDebug On
PythonPath "['/home/projects', '/home/zay2/Django/Django-1.0.2-
final'] + sys.path"

Alias /media/admin "/home/zay2/Django/Django-1.0.2-final/django/
contrib/admin/media"
Alias /media "/var/www/media"

Order allow,deny
Allow from all


SetHandler None


SetHandler None


SetHandler None


There probably is something unnecessary or confusing here, but this is
first time i've installed apache, mod_python, mysql and phpmyadmin so
if you spot room for improvement, let me know.

You can run under Apache using either mod_python or mod_wsgi, start by
taking a look at their documentation:
http://docs.djangoproject.com/en/dev/howto/deployment/modpython/
http://docs.djangoproject.com/en/dev/howto/deployment/modwsgi/

What you want to do is combine these into one urlpattern:

from django.conf.urls.defaults import *

from django.contrib import admin
admin.autodiscover()

urlpatterns = patterns('',
(r'^polls/$', 'mysite.polls.views.index'),
(r'^polls/(?P\d+)/$', 'mysite.polls.views.detail'),
(r'^polls/(?P\d+)/results/$', 'mysite.polls.views.results'),
(r'^polls/(?P\d+)/vote/$', 'mysite.polls.views.vote'),
(r'^admin/(.*)', admin.site.root),
)

Would be the end result.

Absolutely.  Without seeing  your code I'd guess the problem is that you
only have the patterns from part 2 in your URLconf.  You need to make sure
you have the URLs from both parts in your URLconf.

So why not test that theory? You have an hypothesis. Now prove or
disprove.

Put in some debugging printing or logging on the B side and see if the
objects have the "pk" value set. If B doesn't set them and that value is
meant to represent something in the database and the database is meant
to set that value (as part of an auto-increment sequence), then that's
your problem. If the "pk" value isn't set, you know it isn't the
problem.

If it is the problem, one solution would be to make the primary key on
the B side (if it needs to match the value on the A side) not be an
auto-incrementing sequence. Just make it an integer so that you can set
it yourself. It will mean having slightly different model definitions on
the A and B side, but that's life in the big city. If you want the
models to be the same, you'll need to remove the pk value before saving
(set it to None).

Regards,
Malcolm

Saving Deserialized Objects -- Help Needed

[Brian]

I'm having trouble saving deserialied model objects. My setup is that
I have two django instances, let's call them A and B. The intial
request comes into server A which then serializes some objects and
sends them off to server B for the results of some computation. When
server B tries to save the objects sent by A it fails.

I believe the save is failing because the objects already have primary
keys set from server A's database, but are not contained in server B's
database. I could be wrong that this is the reason.

Both django instances are operating the same projects with the same
models. I do need the objects saved, since their relationships are
described in their foreign key relationships, that are used for the
computation.

Any assistance would be very appreciated.

Thank you.

formfield_for_foreignkey help needed.

[mweather]

This is probably really sinple, but I'm pretty new to Sjango, and I
can't seem to figure it out.

I've used Django before, and came back to it once I saw the recent
commit that added ability to override admin formfields, which looks to
be exactly what I need.

I have a Product model and an AffiliateProduct model with a foreign
key to product. I'm trying to get the admin to only display the
AffiliateProduct's currently selected Product in the foreignkey field
(ideally also showing no options if it's blank). I'm using basically
the same code from the example in the admin docs:

class AffiliateProductAdmin(admin.ModelAdmin):
def formfield_for_foreignkey(self, db_field, request, **kwargs):
if db_field.name == "product":
kwargs["queryset"] = Product.object.filter(pk=?)
return db_field.formfield(**kwargs)
return super(AffiliateProductAdmin,
self).formfield_for_foreignkey(db_field, request, **kwargs)

Basically, I need to fill in the ?. I'm not familiar enough with
the innards of Django to even guess where to begin.
