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. A demo site showcasing an example configuration various features, is available in the repository.

Quick start

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

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

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

   CRISPY_ALLOWED_TEMPLATE_PACKS = "bootstrap5"
   CRISPY_TEMPLATE_PACK = "bootstrap5"
   

3. Include the 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 %}
   ...
   <div id="modal-target"></div>
   <script src="https://cdn.jsdelivr.net/npm/jquery@3.7.1/dist/jquery.min.js"></script>
   <script src="https://cdn.jsdelivr.net/npm/jquery-form@4.3.0/dist/jquery.form.min.js"></script>
   <script src="{% static 'crisp_modals/modals.min.js' %}"></script>
   <script>
       $(document).ready(function() {
           $('#modal-target').initModal({
               setup: function (element) {
                   // This function is called for each modal that is opened.
                   // You can add any additional setup code here.
                   ...
               }
           });
       });
   </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. To override the footer buttons, you can use the self.footer.clear() method to remove the default buttons and then add your own.

   from 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)
        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, ModalConfirmView, and ModalDeleteView classes as follows. Include delete_url in the form kwargs for the ModalUpdateView class to show the delete button within the form. By default, the form will be submitted to the same URL as the view, but you can override this by adding a form_action variable to the form keyword arguments.

   from crisp_modals.views import ModalCreateView, ModalUpdateView, ModalDeleteView
   
   class PollCreateView(ModalCreateView):
       model = Poll
       form_class = PollForm
   
   
   class PollEditView(ModalUpdateView):
       model = Poll
       form_class = PollForm
       
   
       def get_form_kwargs(self):
           kwargs = super().get_form_kwargs()
           # If you want the form submitted to a different url, override the `form_action` variable.
           kwargs['form_action'] = ...  # e.g., reverse('polls:poll-update', kwargs={'pk': self.object.pk})
           return kwargs
   
       def get_delete_url(self):
           # If you want to show a delete button in the form, you can return the URL for the delete confirmation view.
           return reverse('polls:poll-delete', kwargs={'pk': self.object.pk})
   
   
   class PollConfirView(ModalConfirmView):
       model = Poll
       
       def get_context_data(self):
           context = super().get_context_data()
           context['title'] = 'Close Poll'
           context['message'] = 'Are you sure you want to close this poll?'
           return context
   
       def confirmed(self, *args, **kwargs):
           # Logic to close the poll
           self.object.close()  # Assuming the Poll model has a close method
           return super().confirmed()
     
   
   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>
   

Note:

The data-modal-url attribute should contain the url of the view that will render the modal. It doesn't have to return a form. Non-form modal content can be rendered by overriding the modal_content block in the modal template crisp_modals/modal.html. The following blocks are available for overriding: modal_header, modal_body, modal_footer, modal_scripts. The modal_scripts block should be used to include any additional JavaScript required for the modal content per-instance. Any code needed for all modals should go in the initModal setup option.
