Django Crispy Forms inside Bootstrap Modals

=================== django-crisp-modals

django-crisp-modals is a Django app which provides support for ajax Django Crispy Forms inside Bootstrap 5 modal dialogs. The app provides various views, form classes, templates and javascript.

Quick start

1. Add "django_crisp_modals", and "crispy_forms" to your INSTALLED_APPS setting like this::

   INSTALLED_APPS = [ ..., "crispy_forms", "crispy_bootstrap5", "django_crisp_modals", ]

2. Add the following to your settings.py file::

   CRISPY_ALLOWED_TEMPLATE_PACKS = "bootstrap5" CRISPY_TEMPLATE_PACK = "bootstrap5"

3. Include the django_crisp_modals/modals.min.js within your base template after jQuery and add a blank modal div to the bottom of the body tag. The modal div should have the id: modal-target. Then initialize the modal target. For example:

   {% load static %}
   ...
   <script src="https://cdn.jsdelivr.net/npm/jquery@3.7.1/dist/jquery.min.js"></script>
   <script src="{% static 'django_crisp_modals/modals.min.js' %}"></script>
   <script>
       $(document).ready(function() {
           $('#modal-target').initModal();
       });
   </script>
   

4. Create forms as follows. The main crispy-forms helper is available as self.body within the forms. A footer helper is also available as self.footer, with submit and reset buttons already included.

   from django_crisp_modals.forms import ModalModelForm, Row, FullWidth
   
    class PollForm(ModalModelForm):
         class Meta:
              model = Poll
              fields = ['question', 'pub_date']
    
    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
        if self.instance.pk:
            self.body.form_action = reverse('polls:poll-update', kwargs={'pk': self.instance.pk})
        else:
            self.body.form_action = reverse('polls:poll-create')
        self.body.append(
            Row(
                FullWidth('question', placeholder='Enter your question'),
            ),
            Row(
                FullWidth('pub_date', placeholder='Enter the publication date'),
            )
        )
   

5. In your views, use the ModalCreateView, ModalUpdateView, and ModalDeleteView classes as follows. Include delete_url in the form kwargs for the ModalUpdateView class to show the delete button within the form.

   from django_crisp_modals.views import ModalCreateView, ModalUpdateView, ModalDeleteView
   
   class PollCreateView(ModalCreateView):
       model = Poll
       form_class = PollForm
   
   class PollCreateView(ModalUpdateView):
       model = Poll
       form_class = PollForm
       
       def get_form_kwargs(self):
           kwargs = super().get_form_kwargs()
           kwargs['delete_url'] = reverse('polls:poll-delete', kwargs={'pk': self.object.pk})
           return kwargs
   
   class PollDeleteView(ModalDeleteView):
       model = Poll
   

6. To distinguish regular links from links that target modals, use the 'data-modal-url' attribute instead of href. For example:

   <a href="#0" data-modal-url="{% url 'polls:poll-create' %}" class="modal-link">Create Poll</a>
   <a href="#0" data-modal-url="{% url 'polls:poll-update' pk=poll.pk %}">Update Poll</a>
