Django inline formsets with bootstrap
Project description
mizdb-inlines
Django inline formsets with bootstrap for the MIZDB app.
Requires django_bootstrap5.
Formsets will be rendered in a layout with two columns. One column is for the formset form, and the other column is for the delete button of a given formset form.
Installation
Install using pip:
pip install mizdb-inlines
Add to your INSTALLED_APPS in your settings.py:
INSTALLED_APPS = [
...,
"mizdb_inlines",
]
Usage
Add mizdb_inlines/js/mizdb_inlines.js javascript and render the formset using the inline_formset template tag from the mizdb_inlines template tag library:
<!DOCTYPE html>
{% load static mizdb_inlines django_bootstrap5 %}
<html lang="en">
<head>
<meta charset="UTF-8">
<title>My Awesome Form</title>
{{ form.media }}
{{ formset.media }}
<script src="{% static 'mizdb_inlines/js/mizdb_inlines.js' %}"></script>
{% bootstrap_css %}
{% bootstrap_javascript %}
</head>
<body>
<form class="container mt-3" method="post">
{% csrf_token %}
{% bootstrap_form form %}
{% inline_formset formset layout="horizontal" %}
{% bootstrap_button button_type="submit" button_class="success" content="Save" %}
{% bootstrap_button button_type="reset" button_class="warning" content="Reset" %}
</form>
</body>
</html>
View mixin for inline formsets
Use the InlineFormsetMixin view mixin to remove some of the boilerplate from handling inline formsets.
Simply declare the formset classes to use in the formset_classes attribute.
from mizdb_inlines.views import InlineFormsetMixin
class MyView(InlineFormsetMixin, UpdateView):
model = Pizza
fields = "__all__"
template_name = "pizza.html"
success_url = "/"
formset_classes = (
inlineformset_factory(Pizza, Toppings, fields="__all__", extra=1),
MyAwesomeFormset,
)
This will add formset instances to the template context with the context variable formsets.
The combined media of the formsets is available with the variable formset_media :
{{ formset_media }}
{% for formset in formsets %}
{% inline_formset formset %}
{% endfor %}
