pip install django-selectize

INSTALLED_APPS = [
# other django apps...
'django_selectize',
]
Quick Start
Here is a quick example to get you started:
We have the following model:
# models.py
from django.conf import settings
from django.db import models
class Book(models.Model):
author = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE)
co_authors = models.ManyToManyField(settings.AUTH_USER_MODEL, related_name='co_authored_by')
Next, we create a model form with custom Selectize widgets.
# forms.py
from django import forms
from django_selectize import forms as s2forms
from . import models
class AuthorWidget(s2forms.SelectizeWidget):
search_fields = [
"username__icontains",
"email__icontains",
]
class CoAuthorsWidget(s2forms.SelectizeMultipleWidget):
search_fields = [
"username__icontains",
"email__icontains",
]
class BookForm(forms.ModelForm):
class Meta:
model = models.Book
fields = "__all__"
widgets = {
"author": AuthorWidget,
"co_authors": CoAuthorsWidget,
}
A simple class based view will do, to render your form:
# views.py
from django.views import generic
from . import forms, models
class BookCreateView(generic.CreateView):
model = models.Book
form_class = forms.BookForm
success_url = "/"
Make sure to add the view to your urls.py:
# urls.py
from django.urls import include, path
from . import views
urlpatterns = [
# ... other patterns
path("", views.BookCreateView.as_view(), name="book-create"),
]
Finally, we need a little template, myapp/templates/myapp/book_form.html
<!DOCTYPE html>
<html lang="en">
<head>
<title>Create Book</title>
{{ form.media.css }}
<style>
input, select {width: 100%}
</style>
</head>
<body>
<h1>Create a new Book</h1>
<form method="POST">
{% csrf_token %}
{{ form.as_p }}
<input type="submit">
</form>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
{{ form.media.js }}
</body>
</html>
