Django Bootstrap Modal Forms

A Django plugin for creating AJAX driven forms in Bootstrap modal.

Live Demo

Installation

Install django-bootstrap-modal-forms:

$ pip install django-bootstrap-modal-forms

Add bootstrap_modal_forms to your INSTALLED_APPS in settings.py:

INSTALLED_APPS = [
    ...
    'bootstrap_modal_forms',
    ...
]

Include Bootstrap, jQuery and jquery.bootstrap.modal.forms.js on every page where you would like to set up the AJAX driven Django forms in Bootstrap modal.

IMPORTANT: Adjust Bootstrap and jQuery file paths to match yours, but include jquery.bootstrap.modal.forms.js exactly as in code bellow.

<head>
    <link rel="stylesheet" href="{% static 'assets/css/bootstrap.css' %}">
</head>

<body>
    <script src="{% static 'assets/js/bootstrap.js' %}"></script>

    <!-- Bootstrap 4 -->
    <script src="{% static 'assets/js/jquery.js' %}"></script>
    <script src="{% static 'js/jquery.bootstrap.modal.forms.js' %}"></script>
    <!-- You can alternatively load the minified version -->
    <script src="{% static 'js/jquery.bootstrap.modal.forms.min.js' %}"></script>

    <!-- Bootstrap 5 -->
    <script src="{% static 'js/bootstrap5.modal.forms.js' %}"></script>
    <!-- You can alternatively load the minified version -->
    <script src="{% static 'js/bootstrap5.modal.forms.min.js' %}"></script>
</body>

How it works?

index.html

<script type="text/javascript">

// BS4
$(document).ready(function() {
    $("#create-book").modalForm({
        formURL: "{% url 'create_book' %}"
    });
});

// BS5
document.addEventListener('DOMContentLoaded', (e) => {
  modalForm(document.getElementById('create-book'), {
    formURL: "{% url 'create_book' %}"
  })
});

</script>

Click event on html element instantiated with modalForm opens modal
Form at formURL is appended to the modal
On submit the form is POSTed via AJAX request to formURL
Unsuccessful POST request returns errors, which are shown in modal
Successful POST request submits the form and redirects to success_url and shows success_message, which are both defined in related Django view

Usage

1. Form

Define BookModelForm and inherit built-in form BSModalModelForm.

forms.py

from .models import Book
from bootstrap_modal_forms.forms import BSModalModelForm

class BookModelForm(BSModalModelForm):
    class Meta:
        model = Book
        fields = ['title', 'author', 'price']

2. Form's html

Define form's html and save it as Django template.

Bootstrap 4 modal elements are used in this example.
Form will POST to formURL defined in #6.
Add class="invalid" or custom errorClass (see paragraph Options) to the elements that wrap the fields.
class="invalid" acts as a flag for the fields having errors after the form has been POSTed.

book/create_book.html

<form method="post" action="">
  {% csrf_token %}

 <div class="modal-header">
    <h5 class="modal-title">Create new Book</h5>
    <button type="button" class="close" data-dismiss="modal" aria-label="Close">
      <span aria-hidden="true">&times;</span>
    </button>
  </div>

  <div class="modal-body">
    {% for field in form %}
      <div class="form-group{% if field.errors %} invalid{% endif %}">
        <label for="{{ field.id_for_label }}">{{ field.label }}</label>
        {{ field }}
        {% for error in field.errors %}
          <p class="help-block">{{ error }}</p>
        {% endfor %}
      </div>
    {% endfor %}
  </div>

  <div class="modal-footer">
    <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
    <button type="submit" class="btn btn-primary">Create</button>
  </div>

</form>

3. Class-based view

Define a class-based view BookCreateView and inherit from built-in generic view BSModalCreateView. BookCreateView processes the form defined in #1, uses the template defined in #2 and redirects to success_url showing success_message.

views.py

from django.urls import reverse_lazy
from .forms import BookModelForm
from .models import Book
from bootstrap_modal_forms.generic import BSModalCreateView

class BookCreateView(BSModalCreateView):
    template_name = 'examples/create_book.html'
    form_class = BookModelForm
    success_message = 'Success: Book was created.'
    success_url = reverse_lazy('index')

4. URL for the view

Define URL for the view in #3.

from django.urls import path
from books import views

urlpatterns = [
    path('', views.Index.as_view(), name='index'),
    path('create/', views.BookCreateView.as_view(), name='create_book'),
]

5. Bootstrap modal and trigger element

Define the Bootstrap modal window and html element triggering modal opening.

Single modal can be used for multiple modalForms in single template (see #6).
When using multiple modals on the same page each modal should have unique id and the same value should also be set as modalID option when instantiating modalForm on trigger element.
Trigger element (in this example button with id="create-book") is used for instantiation of modalForm in #6.
Any element can be trigger element as long as modalForm is bound to it.
Click event on trigger element loads form's html from #2 within <div class="modal-content"></div> and sets action attribute of the form to formURL set in #6.

index.html

<div class="modal fade" tabindex="-1" role="dialog" id="modal">
  <div class="modal-dialog" role="document">
    <div class="modal-content"></div>
  </div>
</div>

<!-- Create book button -->
<button id="create-book" class="btn btn-primary" type="button" name="button">Create book</button>

6. modalForm

Add script to the template from #5 and bind the modalForm to the trigger element. Set BookCreateView URL defined in #4 as formURL property of modalForm.

If you want to create more modalForms in single template using the single modal window from #5, repeat steps #1 to #4, create new trigger element as in #5 and bind the new modalForm with unique URL to it.
Default values for modalID, modalContent, modalForm and errorClass are used in this example, while formURL is customized. If you customize any other option adjust the code of the above examples accordingly.

index.html

<script type="text/javascript">

// BS4
$(document).ready(function() {
    $("#create-book").modalForm({
        formURL: "{% url 'create_book' %}"
    });
});

// BS5
document.addEventListener('DOMContentLoaded', (e) => {
  modalForm(document.getElementById('create-book'), {
    formURL: "{% url 'create_book' %}"
  })
});

</script>

Async create/update with or without modal closing on submit

Set asyncUpdate and asyncSettings settings to create or update objects without page redirection to successUrl and define whether a modal should close or stay opened after form submission. See comments in example below and paragraph modalForm options for explanation of asyncSettings. See examples on how to properly reinstantiate modal forms for all CRUD buttons when using async options.

index.html

<!-- asyncSettings.dataElementId -->
<table id="books-table" class="table">
  <thead>
    ...
  </thead>
  <tbody>
  {% for book in books %}
    <tr>
        ...
        <!-- Update book buttons -->
        <button type="button" class="update-book btn btn-sm btn-primary" data-form-url="{% url 'update_book' book.pk %}">
          <span class="fa fa-pencil"></span>
        </button>
        ...
      </td>
    </tr>
  {% endfor %}
  </tbody>
</table>

<script type="text/javascript">
    $(function () {
        ...

        # asyncSettings.successMessage
        var asyncSuccessMessage = [
          "<div ",
          "style='position:fixed;top:0;z-index:10000;width:100%;border-radius:0;' ",
          "class='alert alert-icon alert-success alert-dismissible fade show mb-0' role='alert'>",
          "Success: Book was updated.",
          "<button type='button' class='close' data-dismiss='alert' aria-label='Close'>",
          "<span aria-hidden='true'>&times;</span>",
          "</button>",
          "</div>",
          "<script>",
          "$('.alert').fadeTo(2000, 500).slideUp(500, function () {$('.alert').slideUp(500).remove();});",
          "<\/script>"
        ].join();

        # asyncSettings.addModalFormFunction
        function updateBookModalForm() {
          $(".update-book").each(function () {
            $(this).modalForm({
              formURL: $(this).data("form-url"),
              asyncUpdate: true,
              asyncSettings: {
                closeOnSubmit: false,
                successMessage: asyncSuccessMessage
                dataUrl: "books/",
                dataElementId: "#books-table",
                dataKey: "table",
                addModalFormFunction: updateBookModalForm
              }
            });
          });
        }
        updateBookModalForm();

        ...
    });
</script>

    // Delete book buttons - formURL is retrieved from the data of the element
    $(".delete-book").each(function () {
        $(this).modalForm({formURL: $(this).data("form-url"), isDeleteForm: true});

See the difference between button triggering Create action and buttons triggering Read, Update and Delete actions.
Within the for loop in .html file the data-form-url attribute of each Update, Read and Delete button should be set to relevant URL with pk argument of the object to be updated, read or deleted.
These data-form-url URLs should than be set as formURLs for modalForms bound to the buttons.

Example 4: Django's forms.Form in Bootstrap modal
