Extracting the database name from an object

[Juan Pablo Romero Méndez]

Hello,

Suppose I get an object from a non-default database:

ob = MyModel.objects.using('somedb').get(pk=1)

Is it possible later to retrieve the database name just from the object?

ob.db??

Regards,

  Juan Pablo

Re: template list empty in with django test client

[Juan Pablo Romero Méndez]

My fault. I was testing from the console. Within an actual test the
request does have the templates.

template list empty in with django test client

[Juan Pablo Romero Méndez]

Hello,

I'm using the django test client, like this:

>>> c = Client()
>>> r = c.get("/content/new/")
>>> r.status_code
200
>>> r.templates
[]

Is this normal?

Prototype: LINQ-esque Manager for Django models

[Juan Pablo Romero Méndez]

Hello,

I've just put a very rough prototype of a db.models.Manager that
allows queries to be specified with lambdas:

Choice.objects.where(lambda c: c.votes >= 1)
Choice.objects.where(lambda c: c.votes != 1)
Choice.objects.where(lambda c: c.poll.question.exact('aaa'))
Choice.objects.where(lambda c: c.poll.question.contains('aa'))
Choice.objects.where(lambda c: c.votes == c.anumber)
Choice.objects.where(lambda c: c.votes > c.anumber)

django admin and static files

[Juan Pablo Romero Méndez]

Hello,

I'm trying to use a custom javascript file in the admin app with Media:


class MyAdmin(admin.ModelAdmin):
class Media:
js = ('js/my.js',)


the problem is that after installing the staticfiles app (in
INSTALLED_APPS) and after setting STATIC_URL = '/media/', the admin
app is unable to find their own admin files.


What could I do?

  Juan Pablo

Re: Question about ModelAdmin.formfield_for_foreignkey

[Juan Pablo Romero Méndez]

I think i solved it. This is the chain of method calls of admin.ModelAdmin:

...
change_view
  get_form
 formfield_for_foreignkey
...

get_form receives the current object as parameter, so all I had to do was to
inject obj in the request:

def get_form(self, request, obj=None, **kwargs):
request.obj = obj
return super(AuthorContenidoAdmin, self).get_form(request, obj,
**kwargs)

and retrieve it later in formfield_for_foreignkey:

def formfield_for_foreignkey(self, db_field, request=None, **kwargs):
obj = request.obj
if db_field.name == 'status' and obj is not None:
allowed_states = [t.destination for t in
 get_allowed_transitions(obj,request.user)]
kwargs['queryset'] = FakeQueryset([get_state(obj)] +
 allowed_states)
return super(AuthorContenidoAdmin,
self).formfield_for_foreignkey(db_field, request, **kwargs)

Re: Select list populated from an object method (admin app)

Ok, I learned about ModelAdmin.formfield_for_foreignkey, which let's me
access the current user.

What I can't find now is the instance asociated the db_field parameter.

Select list populated from an object method (admin app)

[Juan Pablo Romero Méndez]

Hello,

I wonder if there's an easy way to do the following (besides modifying
"contrib.admin.templates.admin.includes.fieldset.html"):

I have a model which uses django-workflows, so for each instance and every
user I can do:   get_allowed_transitions(obj,user), and
obtain a list of Transition objects.

What I'd like is to do is to populate a select list in the change_form  with
the list of transitions allowed for the object.

The tricky thing is that for this list to be calculated, the code needs
access to the current user.

  Juan Pablo

Re: Django Admin template

[Juan Pablo Romero Méndez]

For this, django-google-toolbar is invaluable. It tells you exactly which
templates were used in rendering some url.

Coupled with pycharm's "find file by name" feature (Ctrl+Shift+N) it names
really easy to jump to any name file.

  Juan Pablo

Using different choices in different ModelAdmins

[Juan Pablo Romero Méndez]

Hello,

I'm developing several personalized admin sites (by subclassing
admin.ModelAdmin).

Is it possible to use different Field.choices in a particular field
for each admin site?

The problem is that the choices option is set within the model
definition, not in the ModelAdmin.

Unidirectional relations

[Juan Pablo Romero Méndez]

Hello,

Is it possible to create unidirectional relations within django's orm?

What I mean is a situation where a parent has a children_set of
references to children, but the children don't have any reference to
the father.
