Setting up a MultiValueField + custom model field in admin
Hi guys, Trying to teach myself a bit about creating custom fields (for both forms and models) for Django. Starting off with a somewhat contrived storing a street address in one field. I seem to have gotten the model field working, as I can run python manage.py shell and successfully fill out the field in a model, save the model, retrieve the model, and still have my custom field storing the right data. But when I try to create a corresponding form field to try and tie in to the admin site, what I've currently got throws an error that the "Address" class has no __getitem__ Code is at: http://dpaste.com/126832/ Any pointers as to where I'm going wrong much appreciated. -- You received this message because you are subscribed to the Google Groups "Django users" group.

Hmmm... what are you trying to do by passing the queryset? Doesn't that
send your form everybody's data, instead of just the active user? If I
recall correctly, passing a queryset will initialize a form, so perhaps all
you need to do there is make it a "get" that returns only the current user's
data?

That doesn't look right. I think should be:
form=ModifyProfileForm(initial=data)
But I'm also not sure if your data dict is correct. It should have an item
for each field that you want to initialize.

Again, I don't quite understand why your queryset is using "all" - seems
like you would just want one row ("get"). I'm not sure what the form object
would do with a queryset that has multiple rows. Your dict should be passed
in the second to last line:
form=ModifyProfileForm(initial=initial_dict)
Something like your last line might work, but it is a lot more work than
just passing the form the initialization dict.
Others feel free to jump in here and set me straight as needed. I'm still
fairly new to Django, so I'm no expert... but I've been struggling to learn
the same stuff lately.

Re: ModelMultipleChoiceField with checkboxes: How to generate the HTML "checked" option?
Here's the line from my model:
class UserProfile(models.Model):
some other fields...
privacy_options = models.ManyToManyField(PrivacyOption,
blank=True, null=True, db_table = 'usr_privacy_selection')
Here's the bit from my form:
class ModifyProfileForm(forms.Form):
some other fields...
privacy = forms.ModelMultipleChoiceField(
queryset=PrivacyOption.objects.all(),
required=False,
show_hidden_initial=True,
widget=forms.CheckboxSelectMultiple,
)
Here's whats happening in my view.
When I initialize it like this:
data = {some other fields...
'privacy' : user_profile.privacy_options
}
form=ModifyProfileForm(data)
Then I show it in the template:
{{ form.privacy.label_tag }}
{{ form.privacy }}
{{ form.privacy.errors }}
I get this error:
Caught an exception while rendering: 'ManyRelatedManager' object is
not iterable
So I change the template like so:
{% for privacy in form.privacy.all %}
{{privacy}}
{% endfor %}
and I get this in my browser:
Privacy
* Enter a list of values.
as if it is not displaying any checkboxes because none have a value
set in them yet.
I want to display all checkboxes, and then check the ones which are
set.
I commented out this change in the view, no longer initializing the
form:
#'privacy' : user_profile.privacy_options,
and I still see nothing in my browser, unless I change the template to
this:
{{ form.privacy }}
Then, at least I see all checkboxes:
Privacy
o Show My Profile Page
o Show Expertise
o Show Affiliations
o Show Organization
o Show Contact Info
o Allow Messages
Now, let me uncomment the init again, and try to initialize this form
to the db values:
'ManyRelatedManager' object is not iterable error again.
Trying to set the initial value for this particular field also does
not seem to help:
initial_dict = {}
for x in user_profile.privacy_options.all():
initial_dict[x.name]=True
form=ModifyProfileForm(data)
form.fields['privacy'].initial = initial_dict
The selected options never show up.
I know the selections are being passed to a user_profile instance and
stored in the database. So maybe this is a template rendering issue?
Thanks again,
Gloria

Re: Trouble Getting Past the Congratulations Page
Karen, restarting apache worked instantly. I'm not used to having to do that. Normally it's the browser caching the old page that drives you crazy. Fortunately I have some aliases for starting, stopping, restarting etc that make this really painless. The idea of using the dev server has a lot of appeal, and I was upset when I thought it wouldn't work remotely. I can't have it "listen" to all ip's cause the regular everyday apache server has some of these it's working in the form of production websites. But your syntax for doing runserver with an ip might work for me to just listen for the experimental site. Thanks for your time. I really appreciate it.

You do not need a monitor or keyboard attached to the machine to use the development server. If you can ssh to the machine, you can run the development server. You'll need to tell it to listen on all addresses instead of just loopback: python manage.py runserver 0.0.0.0:8000 0.0.0.0 is all, you could substitute a specific interface IP address if you prefer, but that is all you need to do to be able to reach the development server from a different client machine. When using Apache (unless you have set it up to use mod_wsgi and set things up to do code monitoring to trigger a reload on source code changes) you will need to restart Apache each time you make a code change. Otherwise the existing Apache processes will just keep using the code they've already loaded into memory. My guess is that is what is blocking progress past the congratulations page.

Trouble Getting Past the Congratulations Page
I've been using the book "Python Web Development with Django" to get
up to speed on this amazing framework. Although I'm new to python, I
have plenty of experience with other languages like C and lately PHP,
as well as running my own linux servers using apache2 for websites.
I've been flipping pages learning python (which I really like) and
using the example project, a blog app, as a way to focus the python/
django experience. I've been able to use django-admin startproject to
create a project named mysite (as per the book). manage.py sartapp
blog works fine and manage.py syncdb runs and builds lots of tables
in the mysql db (I've looked at them). The congrats page comes up just
fine. But there it ends. Trying to add the admin application does
not generate any errors, but also does not generate any admin pages...
all I see regardless of what I type in for an url, is that congrats
page.
The details. I'm running debbian lenny as my webserver. This is a
rack-mounted server sitting in my cold garage, and everything I do on
it is via remote login using ssh. It's always worked great. It's
currently happily running several websites using xampp apache2, mysql
and php, originally on debbian sarge. I decided to do some major
upgrades and wanted to migrate to django as well. I upgraded to
debbian lenny and built from source new installations of apache2, php,
mysql, python 2.5 and django 1.1. This took some time because I did
not want to turn off the existing websites, but with about six weeks
of careful work and tons of testing, working path issues, conf files,
etc I have it running the new stuff fine. I can work directly in
python as a programming tool, the new (second) install of mysql does
not get confused with the old one in xampp, and even apache2 comes up
fine so I have both apache2 exceutables running. I have spent time
looking at the django project tutorials, but they are pretty tied into
the development webserver which I cannot run since I have to browser
(or monitor or keyboard) connected to that hardware server. I do have
a happy relationship with the server through ssh and have some spare
domains, one of which I hooked in via apache to the django example.
Again, it seems to work fine as shown by the congrats page when I type
in www.nleashed.com (the domain I'm using). But www.nleashed.com/admin
also shows the congrats page. Bo.
My plan is to rebuild my websites, hopefully doing a LOT of
enhancements as I go, on the django framework and then kill/erase the
whole xampp tree. But this has all ground to a halt when I try to get
the admin app going. Here are the key files:
excerpt of settings.py
INSTALLED_APPS = (
'django.contrib.auth',
'django.contrib.admin',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.sites',
'mysite.blog',
)
entire urls.py
from django.conf.urls.defaults import *
# Uncomment the next two lines to enable the admin:
from django.contrib import admin
admin.autodiscover()
urlpatterns = patterns('',
# Example:
# (r'^mysite/', include('mysite.foo.urls')),
# Uncomment the admin/doc line below and add
'django.contrib.admindocs'
# to INSTALLED_APPS to enable admin documentation:
#(r'^admin/doc/', include('django.contrib.admindocs.urls')),
# Uncomment the next line to enable the admin:
(r'^admin/', include(admin.site.urls)),
)
and finally, the models.py file from the blog dir.
from django.db import models
from django.contrib import admin
class BlogPost (models.Model):
title = models.CharField(max_length=150)
body = models.TextField()
timestamp = models.DateTimeField()
admin.site.register(BlogPost)
As you can see, this is pretty basic stuff, which really worries me --
means I'm failing in a really basic way :)
Any suggestions would be GREATLY appreciated.

You're missing the fact that you already have it, since you are the one who configures Django's port. The client can only contact you on the port it is running on, of course. In other words, the client port number always is the same as the server port number. Gotta be so.

Re: ModelMultipleChoiceField with checkboxes: How to generate the HTML "checked" option?
Hi,
I tried to post this two hours ago, but it did not show up. So sorry
if this is the second copy.
I use "checkboxed" ModelMultipleChoiceField w/o any problems. Here is
a snippet:
class PictureForm(ModelForm):
tags = ModelMultipleChoiceField(queryset=Tag.objects.all(),
widget=CheckboxSelectMultiple, required=False)
class Meta:
model = Picture
fields = ('title', ..., 'tags')
def edit_picture(request, pic_id):
pic = get_object_or_404(Picture, pk=pic_id)
if request.method == "POST":
pic_form= PictureForm(request.POST, instance=pic)
if pic_form.is_valid() and photo_forms.is_valid():
pic_form.save()
else:
pic_form= PictureForm(instance=pic)
return render_to_response("cat/edit_picture.html", dict(
pic_form = pic_form
))
Hope this helps.

You shouldn't have to do that if the data is available in your view. It
should be as easy as passing a dict as "initial" to your form instance you
create in the view:
form = MyForm(initial = {"foo"=True, "bar"=True}
with the field names (instead of foo and bar) of the check boxes you want
checked. Your form then should have them checked when it is rendered.

A Design Question
This is probably outside Django. But I am checking out since I am building it with Django. I am building a specialized closed group social networking web site for special set of medical practitioners. Idea for my client is to be a mini- LinkedIn of sorts for this small community. We want to capture as many details as possible from some clinical practices, to education, work experience, papers submitted etc. However at registration time we want to limit it to just the basic details like name, email and may be some license number. However over a period of time we would like the user to add details. Do I build one large UserProfile Table, with ForeignKey to colleges, specializations etc or do I break it up into number of smaller profiles, and link each profile to a User.

Re: Difficulty using anchor tags in templates
I have seem to overcomplicated and I hope i understand your question right :)
You just need to render the template with your titles and content (i
guess you call it resources).
If you have a link such as link anywhere
on your site, once you click on it you should return HttpResponse and
render your template with titles and content normally.
You don't need HttpResponseRedirect in resources view and you don't
need to do any special handling of fragment id in Django. It is done
by your client (browser).
so instead of
def resources(request):
return HttpResponseRedirect('/resources/')
you would have something like:
def resources(request):
articles = Context({'articles': Articles.objects.all()})
return render_to_response('resources.html', articles)
If anywhere in your resources.html (once it's rendered) there is a
title or any other element which has id="title" your browser will
position that page on that element.
I suggest you read more on fragment identifiers.

Yes, fieldsets are used to decide what form fields to display and how
to lay them out on admin add/change views.
And yes, user would have no knowledge of what data is eventually
written in database at the time of object saving.
I must confess i haven't look into this up until now.
Seems that the add_view checks data passed through GET [1] (which is
of type QueryDict [2]) to see if any of the keys in GET correspond to
the attribute on Model, and if it finds any sets the value of that key
as initial value for the field in the admin form.
You can even set M2M fields this way by giving list of coma separated
PK's through GET for you M2M attribute.
So in your case, you can pass var though GET like so:
/admin/app/article/add/?author=ante
and once it renders your author filed should contain word "ante".
But since you probably do not want to set your defaults directly
through URL you can wrap add_view in your ModelAdmin like this:
class ArticleAdmin(admin.ModelAdmin):
def add_view(self, request, form_url='', extra_context=None):
# GET is immutable QueryDict so we need to get a copy() as
explaind in docs
request.GET = request.GET.copy()
request.GET.update({'author':'ante'})
return super(ArticleAdmin, self).add_view(request,
form_url=form_url, extra_context=extra_context)
When you refresh your article add view author field should contain
value of "ante".
Or if you want a full name of current user you could say:
request.GET.update({'author':request.user.get_full_name()})
I imagine some of core devs or django gurus would maybe have better
ideas on how to do this (or can even tell you if this is documented
somewhere).
As far as readonly fields go i found snippet [3] but i haven't look at
it closely to tell you is it any good or not.
But if you set your fields read only how would you make them editable
if necessary? With JavaScript?

I could be wrong, but to get the desired report to display, I think you may need to revisit your models.py and use the "_set" used in m2m relationships. _mario On Nov 28, 11:50 pm, adelaide_mike wrote: > I have three models: > > class Connector(models.Model): > connectorname = models.CharField(max_length=32) > > class Cable(models.Model): > cablename = models.CharField(max_length=32) > > class Node(models.Model): > connector = models.ForeignKey(Connector) > cable = models.ForeignKey(Cable) > node_specific_data = models.CharField(max_length=32) > > I wish to make a report displaying all Connector names at least once, > and the Cable name that the Node model relates them to.

With assumption you have set your url like:
url(r'^resources/$', 'resources', name='resources')
each time you open "resources" view you would get redirected to the
"resources" view and you have endless loop, which browsers would
terminate after certain number of repetitions.
resources view should return html page with titles and content rather
then redirect to it self.
Basically, when you click on "/some/page/#fid", view which handles
/some/page/ url should return HTML page, and if there is a fragment id
("#fid" in this case) in that page your browser should position your
page on that fragment id (if possible).
Hope i didn't overcomplicated this :)

Have you tried using fieldsets [1] in you ModelAdmin. Also you can
override save_model method on the ModelAdmin to set values for some

Re: How to list all parents and their children if any?
Thanks Karen yet again. Am I right in thinking that this cannot be a symetrical arrangement ie: connector can access values from cable(s) and cable can access values from connector(s) It does not appear to be possible to put a ManyToManyField in both the "parent' models, because one must be declared before the other, and the other is therefore invalid at that time Perhaps there is a work around?

Dynamicly preset forms in the admin interface
Hello,
I'm new to django, so this question may look a bit stupid, but I
couldn't find the information in the documentation.
I have a pretty simple model which looks like this:
class article(models.Model):
headline = models.CharField(max_length=140)
newsentry = models.TextField()
pub_date = models.DateTimeField('date published', null=True,
blank=True)
write_date = models.DateTimeField('started writing')
published = models.BooleanField()
author = models.CharField(max_length=20)
What i want to do now, is that some of these fields are preset when a
new article is written. Lets say a user named Peter is going to write
a new article, then the author field should be preset to "Peter" and
shouldn't be editable. Same thing for write_date, which should be set
to the time Peter started to write this article. How do I do this?
Greets,
Kai

django url and reverse
Hi! In my project most of my views requires the user to be logged in but in some i don't for example the login view wich only displays a login form. When I'm going to the login form as a non logged in user I get an error: "Error was: 'AnonymousUser' object has no attribute 'get_profile'" The error is thrown when I use django reverse or url (from template). It seems as when it checks for urls in my urls.py it parses not only that file to get the url it also tries to execute all views. Thats why I got the error when it executes a view that requires login and therefor uses my user.get_profile(). Anyone know how to solve this? I do wnat to use url and reverse even for pages that doesn't require the user to be logged in.

If this is a direct cut and paste from your code, the problem is in
this bit: {games: "object_list"}
This creates a dictionary with a single entry, whose **name** is the
value of 'games', and the **value** is 'object_list'. I don't think
that's what you want. Put these the other way round.

Flat pages are used to store plain HTML [1], you can't use filter nor
templatetags in them (perhaps you could with some weird middleware or
something but it would not be good solution).
Create custom HTML template for you login view, pass the template name
to your login url pattern (if you don't need custom view) and
everything should work out fine i think.
url(r'^login/$', 'login',
{'template_name': 'registration/login.html'},
name='login'),

Re: View returns no queryset
I suspect that the query isn't being executed, cause you're not
accessing any elements?
have you tried to print games and see what comes out?
passing {games:"object_list"} seems like it should make sense, but
since I'm not an expert on Python or django, I'd imagine that the
"object_list" isn't being hit, hence the no query.
Try the print, and then you'll know if it's a variable in your
template error or something.
Do you have the code that you used when you used a generic view?
