Re: Django Forms vs Angularjs

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
