use Crispy form with ModelForm

Question

I\'ve been running into crispy form, and it seems to do exactly what I want: render forms with bootstrap layout.

Now, the example talk about using forms.Form

Answer 1

I'm the lead developer of django-crispy-forms. I'm not sure I follow your question as it's a bit poorly formatted. What exactly are you trying to do?

django-crispy-forms does work with ModelForms, the same way as with simple forms. It sits on top of Django, so it doesn't mess with it. It only controls your form rendering, but doesn't change how validation works, how to create form instances and so on.

EDIT:

I'm adding an example on how to do a ModelForm with crispy-forms.

class ExampleModelForm(forms.ModelForm):
    def __init__(self, *args, **kwargs):
        super(ExampleModelForm, self).__init__(*args, **kwargs)

        # If you pass FormHelper constructor a form instance
        # It builds a default layout with all its fields
        self.helper = FormHelper(self)

        # You can dynamically adjust your layout
        self.helper.layout.append(Submit('save', 'save'))

    class Meta:
        model = ExampleModel

I believe your first problem is that you were subclassing forms.Form instead of forms.ModelForm. That's why I said that your problem was Django related, not crispy-forms related.

Later in your view:

form = ExampleModelForm()

In your template:

{% load crispy_forms_tags %}
{% crispy form %}
