Re: Django Forms vs Angularjs

I was working on it last couple of days. Basically I came up with what Fabio's solution. Thanks Daniel for 'disabled' field comment as well.

Fabio,

if you are using Django 1.9, you can use the newly introduced disabled attribute on forms.Field, see https://docs.djangoproject.com/ja/1.9/ref/forms/fields/#disabled

self.fields[name].widget.attrs['disabled'] = 'disabled'

self.fields[name].widget.attrs['readonly']=True

is not make real readonly to field, because if user can edit the html on client side, and remove disabled="disabled" and readonly input atributtes

to problem of readonly fields, i currently use this:

https://github.com/luzfcb/django-simple-history/blob/wip-generic-views2/simple_history/forms.py


I prevent it here https://github.com/luzfcb/django-simple-history/blob/wip-generic-views2/simple_history/forms.py#L24

Usage:

class FooBar(models.Model):

    foo = models.TextField(blank=True)

    bar = models.TextField(blank=True)

class MyFooBarForm(forms.ModelForm):

    class Meta:

        object = FooBar

        fields = ('foo', 'bar')

class MyReadOnlyBarForm(ReadOnlyFieldsMixin, forms.ModelForm):

    readonly_fields = ('bar')

    class Meta:

        object = FooBar

        fields = ('foo', 'bar')

my_all_field_readonly_foobarForm = new_readonly_form_class(MyFooBarForm)

my_foo_field_readonly_foobarForm = new_readonly_form_class(MyFooBarForm, readonly_fields=('foo',))

I do not know if this is the best approach, but it was what I got so far.

Actually I do to set permission to each field. A field in the form can be viewable and editable, only viewable, or hidden.  So if user has a permission to see the form, but edit some fields in the form, it gets very tricky especially for validation.

For example I used these statements to make readonly field :

self.fields[name].widget.attrs['disabled'] = 'disabled'

self.fields[name].widget.attrs['readonly']=True

Then the problem rises not to be able send disabled fields in the post.

Maybe you already know this, but you can do a lot of form tinkering in __init__, like so:

    def __init__(self, permissions_parameter=None, *args, **kwargs):

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

        if permissions_parameter:

            #do a bunch of form tinkering
