I believe that there is not other way to do this with AJAX. This is
an asynchronous call to database server. This not refresh your html

Inline Formset

[Emmanuel Oppong Ntiamoah]

Good day friends, Please i have a small challenge, I have an inline formset in 
my admin where users can add more products to a store. The user can also add a 
product if It doesn’t already exist. The problem is when the user adds a new 
product and wants to add more product fields to the Store model the product the 
user added doesn’t show in the dropdown of the new field unless i refresh the 
whole interface.  Please any way to fix this.  
Thanks

m2m field widget to add or update data as inline formset

[Suraj]

Hello everyone,

This may be quite simple, but I am unable to find a widget which will 
function same as m2m widget of django, but will also create new model 
instance if it doesn't exists.

E.g.
If I had models as:
class Outcome(models.Model):
outcome = models.CharField(max_length=255)
outcome_short_name = models.CharField(max_length=10, blank=True, null=
True)


class Course(models.Model):
course_title = models.CharField(
verbose_name=COURSE_SINGULAR + " title", max_length=200, unique=True
)

course_outcome = models.ManyToManyField(
Outcome, verbose_name=COURSE_SINGULAR + " outcome", blank=True
)

Then I want "Outcomes" shown as below while creating course:

[image: Screenshot from 2020-01-28 15-05-09.png]


Now, If the outcomes data added by user already exists, then it should only 
map them to course. Otherwise it should first store outcomes into database 
and then map them to course.


Any guidance in right direction will be highly appreciated.

Thanks,

Inline formset for many to many relation

[Suraj]

Hello Everyone,

I want to inline formset for m2m relationship. Related code looks as 
follows:

models.py
```
class Outcome(models.Model):
# some fields
   # Foreign key is created to make outcomes inline in course form
   course_outcome = models.ForeignKey("course.Course", 
on_delete=models.SET_NULL, blank=True, null=True)

class Course(models.Model):
   # some fields
   course_outcome = models.ManyToManyField(Outcome, 
verbose_name=COURSE_SINGULAR + " outcome", blank=True)
```

forms.py
```
class OutcomeForm(forms.ModelForm):
   # some fields

class CourseForm(forms.ModelForm):
   # some fields including inline outcomes

OutcomeFormSet = 
inlineformset_factory(parent_model=Course, model=Outcome, form=OutcomeForm, 
extra=1, can_delete=True)
```

views.py
```
class CourseCreateForm(CreateView):
   model = Course
   template_name = "course/course_form.html"
   form_class = CourseForm
   success_url = reverse_lazy("course")

   def get_context_data(self, **kwargs):
  context = super(CourseCreateForm, self).get_context_data(**kwargs)
  if self.request.POST:
 context["outcomes"] = OutcomeFormSet(self.request.POST)
  else:
 context["outcomes"] = OutcomeFormSet()
  return context

   def form_valid(self, form, **kwargs):
  super(CourseCreateForm, self).get_context_data(**kwargs)
  context = self.get_context_data()
  outcomes = context["outcomes"]
  with transaction.atomic():
 if outcomes.is_valid():
self.object = form.save()
outcomes.instance = self.object
outcomes.save()
  
  
form.instance.course_outcome.set(Outcome.objects.filter(course_outcome=self.object))
form.save()
  return super().form_valid(form)
```

All my data in Outcome and Course models saved successfully except m2m 
field of course model.
Can anyone please guide me what I am doing wrong here.

Thanks in advance,

Unable to save m2m field in Inline Formset with many to many relation in django CreateView

[Suraj]

Hello everyone,

I am unable to make it worked. I have two models "Course" and "Outcome". I 
want to make OutcomeForm form as inline form in CourseForm.

My models.py file looks as below:


class Outcome(models.Model):# some fields
course_outcome = models.ForeignKey(
"course.Course", on_delete=models.SET_NULL, blank=True, null=True)
class Course(models.Model):# some fields
course_outcome = models.ManyToManyField(
Outcome, verbose_name=COURSE_SINGULAR + " outcome", blank=True)


And inline formset is created as:


OutcomeFormSet = inlineformset_factory(
parent_model=Course,
model=Outcome,
form=OutcomeForm,
extra=1,
can_delete=True,)


And views.py file is:

class CourseCreateForm(CreateView):
model = Course
template_name = "course/course_form.html"
form_class = CourseForm
success_url = reverse_lazy("course")

def get_context_data(self, **kwargs):
context = super(CourseCreateForm, self).get_context_data(**kwargs)
if self.request.POST:
context["outcomes"] = OutcomeFormSet(self.request.POST)
else:
context["outcomes"] = OutcomeFormSet()
return context

def form_valid(self, form, **kwargs):
super(CourseCreateForm, self).get_context_data(**kwargs)
context = self.get_context_data()   
outcomes = context["outcomes"]
with transaction.atomic():
if outcomes.is_valid():
self.object = form.save()
outcomes.instance = self.object
outcomes.save()
form.instance.course_outcome.set(
Outcome.objects.filter(course_outcome=self.object)
)
form.save()
return super().form_valid(form)



The problem is:

All data of model Outcome and Course is saved except m2m field of Course 
model.

I am stuck at this point. Any pointer in right direction will be highly 
useful.

Thanks in advance,

inlineformset_factory displays only inline formset, doesn't show parent model

[Nkansah Rexford]

I have this:

# consider all importations done right.

def add_noodle(request):NoodleFormSet = inlineformset_factory(Noodle, 
tutImages, form=NoodleForm, fields=('title', 'image'))if request.method 
== 'POST':formset = NoodleFormSet(request.POST, request.FILES)  
  if formset.is_valid():formset.save()else:formset 
= NoodleFormSet()return render_to_response('add_noodle.html', {
'formset': formset,})
I only get 3 tutImages model rendered in the template, without the Noodle 
model showing. I've been reading 
this: https://docs.djangoproject.com/en/dev/topics/forms/modelforms/ but 
don't seem to get what it means or what its trying to say with regards to 
the inlineformsets_factory.

I read the part 

> NoodleFormSet = inlineformset_factory(Noodle, tutImages, form=NoodleForm, 
> fields=('title', 'image'))


as

'Create an inline factory using tutImages Model (3 of them, alterable using 
> the extra=n param) under Noodle model, using NoodleForm (which tells it the 
> fields of Noodle model to expose to template)'


That doesn't work right. I'm missing something? Please help. Thanks

Re: Django Inline formset with jquery

[aRkadeFR]

Hello,

I got the same kind of probleme while working on the formset
couple days ago.

If this is related, the problem is the auto complete javascript that
doesn't go well with the jquery.formset.js.

You can add a function "added" in parameter of the formset function
for reloading the autocomplete widget.

something like:
```
|
$(function() {
$(".inline.{{ orderformset.prefix }}").formset({
prefix: "{{ orderformset.prefix }}",
added: function () { reload_auto_complete(); },
})
})
|
```

About the deletion, is it on the front end or the backend you're
talking about?

If this is front -> check your javascript
If this is backend -> check all the values dumping request.POST

Hope I was useful

Re: CBV with inline formset

[Dan Gentry]

I created a couple of mixins for a project that might help you.  See this 
gist: https://gist.github.com/dashdrum/03858d79ddfd9bba44d6

Pretty easy to use.  Here's an example Create view:

class RegistrationView(FormsetCreateMixin,CreateView):
template_name = 'registration/registration_form.html'
model = RegistrationMaster
form_class = RegistrationForm
detail_form_class = RegDetailFormSet


The mixin creates a new class variable: detail_form_class.  Set this in the 
view class declaration to point to your formset.  

I haven't tested this beyond the one project, so please tread carefully.  I 
hope this can at least get you moving in the right direction.

CBV with inline formset

[Brad Rice]

I've pretty much butchered the code for 3 days now and cannot figure out 
how to insert an inline formset. Can anybody help me?

I've tried to pare everything down to use two simple Models just to try to 
get an insert. I'm using django Author - Book relationship to keep it 
simple.

class Author(models.Model):
name = models.CharField(max_length=100)

def __unicode__(self):  # __unicode__ on Python 2
return self.name


class Book(models.Model):
name = models.CharField(max_length=100)
author = models.ForeignKey(Author)

So I have a page where you can insert and author. The author page takes you 
to a page to insert books for that author using an inline formset of 3 
books.

In my urls.py I have this url url(r'^book_create/(?P\d+)/$', 
BookCreate.as_view(), name='book_create'),

When you go to book_create I can see the author_id getting passed in the 
kwargs. Now how to I insert from there books into the db with the Foreign 
Key to that author passed in the kwargs?

After banging away for so long, I decided to try to switch to django extra 
views. this is what I have in my views.py

class BookCreate(InlineFormSetView):
model = Author
inline_model = Book
form_class = BookForm
extra = 3
template_name = 'book_template.html'

def get_queryset(self):
slug = self.kwargs['author_id']
return super(BookCreate, self).get_queryset().filter(id=slug)

When I go to the book_create page I get this error:

Generic detail view BookCreate must be called with either an object pk or a 
slug.

Re: Inline formset with different default values for each "extra" row

[Chris Cogdon]

Because Lee Hinde's thread is broken, I'm going to take a punt at what the 
question is :)

in a formset (inline, model, or just a plain one), the "initial" parameter 
to the instantiation of the form takes an list of dictionaries. Each 
element in the list is the initial data for _that_ row... so if you want 5 
different part numbers, for example, do this.


formset = MyFormSet ( ..other params.., 
 
initial=[{'partno':10},{'partno':11},{'partno':12},{'partno':13},{'partno':14}] 
)

Inline formset with different default values for each "extra" row

[Lee Hinde]

For a product up to three different vendors have been identified and I want
to present a row per vendor (which is a fk) so that the user could select
order quantities from each vendor.

If a vendor doesn't have an order quantity, I'd want to ignore it at
form.save() time, rather than reject it.

Pointers are appreciated.

Validation error by working with inline formset

In my django project I've working with inline formset factory to join
two forms, so when i try to edit the main form this error happens

my models.py is:

my forms.py is :

ImagenFormSet = inlineformset_factory(Articulo,Imagenes)

Re: Problem with a clean in inline formset

[Ernesto Guevara]

Solution:

def clean(self):
   if any(self.errors):
   # Don't bother validating the formset unless each form is
valid on its own
   return
   for i in range(0, self.total_form_count()):
   form = self.forms[i]
   cleaned_data = form.clean()
   display = cleaned_data.get('display', None)
   if cleaned_data['DELETE'] == False:
 if display.max_windows() >= display.windows:
   raise forms.ValidationError("The display have all
windows occupied.")

Put the line if cleaned_data['DELETE'] == False:  to check if the inline
have the attribute DELETE and if is false, to ignore deleted rows in
formset that have true in this attribute. =)

Problem with a clean in inline formset

[Guevara]

Hello!

The (if display.max_windows() >= display.windows) works fine to
prevent insert. Behaves as expected.
But is raised even when the row is REMOVED from the edit formset. =/

## Models

class Display(models.Model):
windows = models.IntegerField()

def max_windows(self):
total = self.window_set.all().count() #window is a
intermediary class to campaign
if total:
return total

## Clean method in CampaignInlineFormSet

def clean(self):
if any(self.errors):
# Don't bother validating the formset unless each form is
valid on its own
return
for i in range(0, self.total_form_count()):
form = self.forms[i]
cleaned_data = form.clean()
display = cleaned_data.get('display', None)
if display.max_windows() >= display.windows:
raise forms.ValidationError("The display have all
windows occupied.")

This "if" can not stop me remove a row in inline formset. How can I
fix this?
Regards.

Verifying number of forms in inline formset

[Michael Stevens]

Hi.

I've got a django app using an inline formset.

It was all working nicely, but I want to add some validation such that the 
inline formset must contain at least one valid record. This seems to be 
surprisingly hard to do.

I've tried overriding clean() on the formset and looking at things like 
self.form, is_valid(), and so on, but I can't work out anything that will 
let me know the number of database records that will be present when the 
formset is saved.

Am I missing anything obvious? How could I do this?

Re: Inline formset factory ignores 'exclude=' for foreign key field

[gulrtosk]

Right, I don't know whether this is a bug or done on purpose ... It looks 
like it was done on purpose so I'd be happy to hear the experts on this. 
I'm using Django 1.3. I hope I got this right.

On line 752 of django.forms.models (development trunk), in the add_fields() 
method of BaseInlineFormSet it says:

name = self.fk.name
...
form.fields[name] = InlineForeignKeyField(self.instance, **kwargs)

This is *after* all processing of 'fields=' and 'exclude=' kwargs has been 
done on the form. Consequently, for all inline form sets the foreign key 
field is always included. It is not possible to 'exclude=' it. Any opinions 
on why this should be so?

Inline formset factory ignores 'exclude=' for foreign key field

[gulrtosk]

Hello list,

through trial and error I discovered that it isn't required to pass the 
foreign key form field post data to the constructor of an inline form set. 
Django will fill it in automatically by looking at the primary key of the 
'instance=' given. So I figured I might as well exclude the hidden FK field 
from the form:

class Group(models.Model):
interest = models.CharField(max_length=100)
class Member(models.Model):
name = models.CharField(max_length=100)
group = models.ForeignKey(Group)

MemberFormSet = inlineformset_factory(Group, Member, exclude=('group',))

The 'exclude=' instruction is ignored and the form is printed the same as 
without 'exclude=('group',)'. This is odd, since the FKs aren't strictly 
required in the form set: if you pass post data *with* foreign key fields 
to the constructor MemberFormSet(), Django will use it for validation, but 
if you don't pass them, it's fine too, because Django will simply use the 
instance to fill them in automatically.

So, how can I exclude my 'group' foreign keys from the printed form set?

Thank you and cheers, glts

Re: How do I override default behaviour for foreign keys in an inline formset?

Though I originally asked for a "detailed solution", even some

How do I override default behaviour for foreign keys in an inline formset?

[King]

I want to do something like this...
http://groups.google.com/group/django-users/browse_thread/thread/db03fa90a14ecc6a
...but unfortunately there was no reply to this particular posting.
I've found other posts on the web of people looking for the same sort
of solution, and have not been able to find any helpful answers, so I
was hoping someone here could clear this up.

For example, let's say I had an app that kept a list of books for each
user like this:

class BookList(models.Model):
user = models.ForeignKey(User)
book = models.ForeignKey(Book)

class Book(models.Model):
author = models.ForeignKey(Author)
name = models.CharField(max_length=300)

class Author(models.Model):
name = models.CharField(max_length=300)

I had thought that to generate a bunch of forms for BookList (so that
the current user could for example, enter in all of the books that
they've read on a single page), I would use an inlineformset like so:

BookListFormSet = inlineformset_factory(User, BookList)
booklist_formset = BookListFormSet(instance=currentUser)

However, the resulting formset I get results in a dropdown menu for
each book field in the forms, but I don't want that. I want two
TextInput widgets in the form such that the user can type out:
   Alice in Wonderland
   Lewis Carroll
and if some other user has already added "Alice in Wonderland" to
their book list, then BookList.book will just point to that book.  BUT
if this is the first user to add "Alice in Wonderland" to their book
list, I want the form to create a brand new row in the Book table (and
a brand new row in Author if there is no "Lewis Carroll" books yet
either).

I'm new to Django, so maybe the solution is obvious to many.  But like
I said, I'm finding lots of people asking this question, but without
any good answers posted.

If someone could please provide a detailed solution I would very much
appreciate it, and I imagine others would as well.

Thanks in advance.  If any part of what I'm asking isn't clear, don't
hesitate to ask me about it.

admin inline formset using incorrect form

[shanyu]

Hi, please take a look at the following code.

def create_foo_form(baz):
class FooForm(forms.ModelForm):
   def __init__(self, *args, **kwargs):
   print "Initializing a FooForm object"
   # Init stuff here
return FooForm

class FooInline(admin.TabularInline):
model = Foo

def get_formset(self, request, obj=None, **kwargs):
if obj:
kwargs['form'] = create_foo_form(obj)
return super(FooInline, self).get_formset(request, obj,
**kwargs)

class BazAdmin(admin.ModelAdmin):
inlines = [FooInline,]


Suppose we are changing a Baz object. First, get_formset method will
be passed the Baz object as obj and following that a FooForm class
will be created and passed to the superclass method.

Here's the part that's beyond my understanding: After that,
get_formset gets executed for an extra time with obj=None. Because obj
is None, the method doesn't pass FooForm to the superclass method, and
therefore the superclass is expected to construct the formset using
default form (self.form - which is not FooForm). But to my surprise I
am getting FooForm objects initialized.

So I have 2 questions:
1. Why does get_formset get called an extra time with obj=None?
2. Why are FooForm objects used when a formset is constructed in this
second time?

Regards.

Re: inline formset validation error

[Shawn Milochik]

You can iterate through the forms in your formset and call is_valid()
(and optionally save()) on them based on your needs.

Since your definition of "left blank" and "invalid" could vary based
on what you're doing, it's better that you make those decisions
explicit. If Django tried to decide for you, it would be "magic" at
best and wrong at worst.

inline formset validation error

[Sarang]

I have an inline formset that has max_num=3 and extra=3. The form is 
displayed correctly, however, is_valid() on the formset returns a False with 
error:
[{}, {'tag': [u'This field is required.']}, {'tag': [u'This field is 
required.']}]

The first form has no error as the user has set some value to the field 
"tag". However, the user has not touched the other two forms. 

I thought the extra forms are optional isn't it? If their data is not valid, 
shouldn't Django ignore them and move on? Am I doing something wrong and is 
there a workaround to this problem?

Thanks

Django inline formset gotcha

[h3]

I've been banging my head on this problem for many hours and nobody
came up with a
working solution ..

I've tried so many things to work around this problem that I've
decided to write a blog
listing them to save you all some time:

http://haineault.com/blog/141/

TL;DR: inline formset + post_save signal = cannot access inlines'
updated data.

Think of an invoice system were the inlines are the invoice's lines
which you use to
calculate the invoice's total.

You just can't have that total upon save nor with post_save signal
under *any* circumstances.
Unless you hit the save button twice, then the second time the right
total will show up. Of
course this is problematic on many levels, but in my case I need to
send an email with the
actual data after the save.

Please someone tell me I'm retarded and that there is a simple obvious
solution hidden in plain
sigh that escaped me.

I'm trying to do some custom validation for an inlineformset.  I would
like to only allow 5 items checked across the forms in the inline

Inline formset when pk doesn't exist

[cerberos]

I have 2 models

class Item(models.Model):
fields here

class ItemImage(models.Model):
item = models.ForeignKey('Item', null=True, blank=True,
related_name='images')

I want a single 'form' where a user can add an Item and an ItemImage
(actually many images but that's irrelevant at this stage). I want to
use an inline formset but the Item instance doesn't exist so there's
no primary key, I have tried but get an error relating the the lack of
primary key (...django/forms/models.py in _get_foreign_key, line 796).

I'm pretty sure this can't be done with inline formsets so I figure
that I should add an ItemImage formset to the Item form somehow, I
just don't know how (and it doesn't seem to be covered in the docs).

I'd appreciate any help I can get as I've hit a brick wall.

Many thanks

Inline formset customization

[pinco]

Hi Guys,

I'm try to figure out how add some customized functionalities to an
inline formset. What I would implement are the two following features:
- ability to delete a record by pressing a submit button assigned to
each row (instead of checking the delete box and submitting the
overall form)
- ability to preserve the extra forms number and order after the
submission

To better explain the second point, suppose there are 3 records on the
db and the user adds 3 extra forms (using eg. the technique described
here: 
http://www.falconhat.com/tutorials/django-adding-inline-formset-rows-without-javascript/).
The user then decides to delete the second record.
I would that, after the submission, the form has 2 records and 3
extra, blank forms. Additionally, if the user fills partially one or
more of the additional forms, I would the filled forms to keep the new
content.

Can somebody give me some hints on how to implement these
functionalities?
By the way, while the above functionalities seem to be easy to
implement using JavaScript, I'm keen to avoid to use it.


Many thanks for your invaluable help.


Cheers,

Paolo

custom validation for an inline formset, howto?

[dan levine]

I am trying to perform custom validation on an inline formset.  The
docs indicate that custom formset validation should go through a
custom clean method:

http://docs.djangoproject.com/en/1.1/topics/forms/formsets/#custom-formset-validation

but the clean method doesn't get called for my instance of an inline
formset when I call is_valid() on the formset.

Conceptually, I have Client model with many PhoneNumber models for my
inline formset, and want to do some validation on the phone number
fields based on fields in client.  The relevant code snippets for my
project:

custom form code:

class BaseClientPhoneInlineFormSet(BaseInlineFormSet):
  # do nothing pass-through method, but see that logging statement
prints
  def __init__(self, data=None, files=None, instance=None,
   save_as_new=False, prefix=None):
logging.debug("IN client.forms.BaseClientPhoneFormset.__init__")
super(BaseClientPhoneInlineFormSet, self).__init__(data, files,
instance, save_as_new, prefix)

  # this should do validation, but doesnt.  this logging statement
never prints
  def clean(self):
logging.debug("IN client.forms.BaseClientPhoneFormset.clean")
super(BaseClientPhoneInlineFormSet, self).clean()
raise forms.ValidationError("Test Inline Formset Clean Fail.")


view code:

  ClientPhoneFormSet = inlineformset_factory(models.Client,
models.PhoneNumber, formset=BaseClientPhoneInlineFormSet)
  formset = ClientPhoneFormSet(request.POST, instance=client_ref)
  formset.is_valid():  # no validation error thrown, returns true


The __init__ logging message is output, but the clean logging message
is not, and no ValidationError is thown on is_valid().

I've searched and not found any similar questions which makes me think
I'm missing something obvious :-/

Thanks for any help.

This looks like a bug somewhere along the line of processing that sequence
(save-as that fails due to a validation error for an object with at least
one inline, correct the error, try to save again), though I'm not sure
where.  I don't recall this being reported before so if you could open a
ticket for it that would be good.

Save as inline formset

[oiad]

Hi. If I have a couple of models like these:

class Poll(models.Model):
question = models.CharField(max_length=200, unique = True)
pub_date = models.DateTimeField('date published')

class Choice(models.Model):

The foreign key and the id's are missing.
Did someone else had this error? Is it a django bug? Am I doing

inline formset

[Frédéric Burlet]

Hi,

I'm a bit stuck with inline formset. I missed something.
I'm using django 1.1.1.

I have a model:

class Address(models.Model):
street = ...
number = ...
...

class Person(models.Model):
first_name = ...
last_name =
address = models.ForeignKey(Address)
...

Based on this model, I would like to have one form to add a person and her 
address. In order to achieve this, I'm using inline formset.

As far as I understood, formset allows to add multiple form on a page and 
inline formset is an extension that allows to play with related objects.

I written the following view (based on the documentation located at [1])

[1] http://docs.djangoproject.com/en/1.1/topics/forms/modelforms/#inline-
formsets

def add_person_form(request):

address = Address()
PersonFormSet = inlineformset_factory(Address, Person, max_num = 1, 
can_delete = False)

if request.method == 'POST':
formset = PersonFormSet(request.POST, request.FILES, instance = 
address)
if formset.is_valid():
formset.save()
return redirect('/person')
else:
formset = PersonFormSet(instance = address)
return render_to_response('person/add_form.html', { "formset": formset } )


My template looks like (simplified version):


 {{ formset }}


This only displays the person but not the address.

Extra question: if I want to display the fields in a given order, let's say: 
first_name, last_name, and then all fields from Address object followed by the 
remaining fields from Person. What is the best way of doing it ?

Thanks for your support,

Frédéric Burlet.

First, 1.2 does not yet exist.  It's in development.  Perhaps you mean you
updated to a recent SVN checkout?

Second, you updated JUST the Django forms directory from 1.0 to ?  If so, yes, that is the problem. The line having the problem is in
django/forms, it is a line added (I think) during 1.1 development, and it
requires other code changes made elsewhere in the Django code base.  You
cannot simply update subdirectories within django individually. Django is an
integrated package: you need update the whole thing, or not at all.

filter foreign key field in inline formset

[cerberos]

One of the fields in an inline formset has a foreign key to another
model, how can I filter it?

I'm building a library system, the models are loans, loan items and
book instances. I don't want books that are currently out on loan to
be available on the loan items dropdown list.

Inline formset question

[Aizen]

I have the following models and I'd like to use them to generate a
contact form...now I know I'm suppossed to use inline formsets, but
I've never been able to make heads or tails of how to make this
work...I want to have the first name, last name, email, phone number,
best time to contact, and the message in my view.  How should I go
about this?

class BestTime(models.Model):
  contact_time = models.CharField(max_length=20)
  start_time = models.TimeField()
  end_time = models.TimeField()
  def __unicode__(self):
return self.contact_time

Hello,
How can I render new form for object X and inline formset for model Y
(with foreign key to X) on the same- the same way it's done in django-
admin.

I've been struggling with it for a while, I tried to render form and

Inline Formset Validation

[KRH]

A question on forms; I had asked something similar on StackOverflow
but found the solution didn't really work for me. Let's say I have an
Article class and a Photo class, and I want to be able to attach
Photos to Articles. I create an ArticlePhotoSet class, and make it an
InlineForm in the Article's Admin class. Here's the problem:

Articles can be assigned to a site, and Photos can be assigned to a
site. Each time an Article is saved in the admin, the form needs to
throw an error if any of the Photos pointed to by the ArticlePhotoSet
inlines don't belong to the same site(s) that the Article does. The
problem is that in the ArticlePhotoSet formset, self.instance in the
clean() function refers to what is currently saved for the article,
not what the Article form is 'proposing' the new site be in the form.
So any check placed in the ArticlePhotoSet formset clean() is
referring to what the site value is, not what it will be. Conversely,
the formset doesn't seem to be accessible from the cleaning method of
the Article form itself, so the Article's form can't do the check. Is
there a way to do what I'm trying to accomplish without falling back
onto something more extreme like AJAX checks when the Article's site
value is changed on the form?

Custom validation for inline formset in Admin

[ljholish]

I have a UserProfile related to auth's User model with a couple of
extra date fields, start_date and end_date. I would like one and only
one UserProfile that is editable inline with the parent User model in
my Admin app. This part is working, but I would also like to do custom
validation on the date fields in UserProfile so that start_date <
end_date and also make sure that the lone UserProfile does not have a
delete checkbox in the Admin. Here is a bit of the code:

models.py:

class UserProfile(models.Model):
user = models.ForeignKey(User, unique=True)
start_date = models.DateField()
end_date = models.DateField()

admin.py:

class UserProfileInlineFormSet(BaseInlineFormSet):

def __init__(self, *args, **kwargs):
super(UserProfileInlineFormSet, self).__init__(self, *args,
**kwargs)
self.can_delete = False

# Validate end_date > start_date
def clean(self): # ?
pass

class UserProfileInline(admin.TabularInline):
model = UserProfile
fk_name = 'user'
max_num = 1
formset = UserProfileInlineFormSet

class MyUserAdmin(admin.UserAdmin):
inlines = [UserProfileInline, ]

The docs explain how to do custom validation on a single ModelForm,
but I'm having trouble abstracting that to an inline formset. I
started with trying to define my own formset in the UserProfileInline
class, but I'm not clear on what method to override in order to do the
validation. Any tips or pointers?

Inline Formset Question

[Ardesco]

Hi everyone. I still consider myself to be fairly new to Django, and I
was wondering if the following was possible with inline formsets in
the admin:

I want to create a little questionnaire app in the admin that is pre-
populated with 25 questions in a specific order such that all the user
has to do is click on the response (as opposed to selecting a question
AND an answer). I have little/no experience using formsets, but I was
wondering if this was easily do-able. As a further caveat, I would
really like it if I could pre-populate questions from my database, as
opposed to hardcoding initial values in admin.py. Is this feasible?
Can someone explain/show some code snippets that explains what I want
to do?

I included the View and Model in my original post, I reproduce it here
in case you don't have access to the whole thread:

Here's the view, the Parent model is "Articulo", the inline model is
"Archivo":

ArchivoInlineFormSet = inlineformset_factory(Articulo, Archivo,
extra=3)
@login_required
def create_article(request, id=False):
text = "Enviar"
button = "Enviar"
user = request.user
if request.method == 'POST':
#save data for new article
form = ArticuloForm(request.POST, request.FILES)
if form.is_valid():
#save info
articulo = form.save()
articulo.autores.add(user.get_profile())
articulo.save()
formset = ArchivoInlineFormSet(request.POST,
request.FILES,  instance=articulo)
if formset.is_valid():
formset.save()
else:
#start editing new article
form = ArticuloForm()
formset = ArchivoInlineFormSet()
objContext = RequestContext(request, locals())
return render_to_response("editar/articulo.html", objContext)

--

And the class, the troublesome field is "archivo":

class Archivo(models.Model):
articulo = models.ForeignKey(Articulo)
tipo = models.IntegerField()
numero = models.IntegerField()
archivo = models.FileField(upload_to="archivos")
etapa = models.IntegerField()

This depends on how you're using the formset. In order not to raise an
error, the form field involved has to know that there is a previous
value and what it is. The standard FileField form field already does
that (if no data is submitted and the "initial" value on the field is
set, it passes validation).

Displaying the initial value for file fields is something that has to be
done manually in form display, from memory.

So, perhaps you could give a small, reduced to the minimum, example of
how you're setting all this up. Maybe it's a problem in inline formsets,
or maybe it's an oversight in your code. At the moment, hard to tell.

Regards,
Malcolm

I see. If there's no way to set the initial value for the field, would
there be some way to make Django not return an error when the user
tries to save the field without re-uploading the file? And maybe
display the current value so the user knows it's already uploaded (as
the admin site does)?

This isn't a Django issue. It's a standard property of browsers: you
can't set an initial value for file input fields. This is a security
measure, to stop malicious pages uploading files from your hard drive
without your explicit instruction.

There isn't really any way round it, except to do something extremely
complicated like GMail does and upload the file in the background
while the user fills in the form, then replace the file field with a
reference to the uploaded version of the file.

Bound Inline Formset doesn't render FileField's current value, needs to be reentered.

[Rodrigo C.]

I have model that represents a file, and has a FileField, that I am
rendering via an Inline Formset. When a user fills in the form it gets
saved with no problems.
However, I want the users to be able to continue editing the file, but
when I re-display the newly created object, the data for the FileField
doesn't show, so if the user edits some data but doesn't re-upload the
file, she gets an error.
How can I make the formset render the FileField's current value within
the form field?

Here's the view, the Parent model is "Articulo", the inline model is
"Archivo":

ArchivoInlineFormSet = inlineformset_factory(Articulo, Archivo,
extra=3)

@login_required
def create_article(request, id=False):
text = "Enviar"
button = "Enviar"
user = request.user

if request.method == 'POST':
#save data for new article
form = ArticuloForm(request.POST, request.FILES)

if form.is_valid():
#save info
articulo = form.save()
articulo.autores.add(user.get_profile())
articulo.save()

formset = ArchivoInlineFormSet(request.POST,
request.FILES,  instance=articulo)
if formset.is_valid():
formset.save()

else:
#start editing new article
form = ArticuloForm()
formset = ArchivoInlineFormSet()

objContext = RequestContext(request, locals())
return render_to_response("editar/articulo.html", objContext)

and the class, the troublesome field is "archivo":

Thank you, I'll look into that.

You're not really modifying django, since you can include the templats  
in your templates folder, and override them.

If you want app specific admin templates, one way is to wrap the admin  
views -- for example, see:

http://trac.django-cms.org/trac/browser/trunk/cms/admin_views.py

Well, it's not true that you can't change the inline template for a
model - you can easily do so by using the 'template' attribute in the
InlineModelAdmin class, see here:
http://docs.djangoproject.com/en/dev/ref/contrib/admin/#inlinemodeladmin-objects

However a better solution would probably be to define your own custom
formset for the inline model, and set can_delete to false there. For
example:

from django.forms import models
from django.contrib import admin

class MyInline(models.BaseInlineFormset):
def __init__(self, *args, **kwargs):
super(MyInline, self).__init__(*args, **kwargs)
self.can_delete = False

class InlineOptions(admin.StackedInline):
model = InlineModel
formset = MyInline

class MainOptions(admin.ModelAdmin):
model = MainModel
inlines = [InlineOptions]

Hi David,
thanks for your reply.
I just did in fact, but that affects every single inline form in the
project, and that's not what I want. There's no way to load inline
template (in admin) for selected app from what I learned. And I'd
rather not modify anything in django code because i don't really
consider that as solution.
Is there any other way?

Have you tried editing the admin templates to not show the checkbox?

disable delete checkbox in Inline formset

[Kurczak]

Hi there,
Is there any way to disable/remove the delete checkbox for inline
formsets ( in admin) ?
I found nothing about it in docs, and I believe there's no way to pass
the 'can_delete' parameter to inlineformset_factory. Obviously I can
disable the "Can delete" permission, but the ugly box is still there.

Can anyone help me out with that matter?
Cheers!
