Below is an example of an action that will display a form after clicking on the action button on the detail object page.
# admin.py
from django import forms
from django.contrib.auth.models import User
from django.http import HttpRequest
from django.shortcuts import render
from django.urls import reverse_lazy
from django.utils.translation import gettext_lazy as _
from unfold.admin import ModelAdmin
from unfold.decorators import action
from unfold.widgets import UnfoldAdminTextInputWidget, UnfoldAdminSplitDateTimeWidget
class SomeForm(forms.Form):
# It is important to set a widget coming from Unfold
date_start = forms.SplitDateTimeField(label=_("Start"), widget=UnfoldAdminSplitDateTimeWidget)
date_end = forms.SplitDateTimeField(label=_("End"), widget=UnfoldAdminSplitDateTimeWidget)
note = forms.CharField(label=_("Note"), widget=UnfoldAdminTextInputWidget)
# Loads date widget required JS files
class Media:
js = [
"admin/js/vendor/jquery/jquery.js",
"admin/js/jquery.init.js",
"admin/js/calendar.js",
"admin/js/admin/DateTimeShortcuts.js",
"admin/js/core.js",
]
@register(User)
class UserAdmin(ModelAdmin):
actions_detail = ["change_detail_action"]
@action(description=_("Change detail action"), url_path="change-detail-action")
def change_detail_action(self, request: HttpRequest, object_id: int) -> str:
# Check if object already exists, otherwise returs 404
obj = get_object_or_404(User, pk=object_id)
form = SomeForm(request.POST or None)
if request.method == "POST" and form.is_valid():
# Process form data
# form.cleaned_data["note"]
# form.cleaned_data["date_from"]
# form.cleaned_data["date_to"]
messages.success(request, _("Change detail action has been successful."))
return redirect(
reverse_lazy("admin:app_model_change", args=[object_id])
)
return render(
request,
"some/action.html",
{
"form": form,
"object": obj,
"title": _("Change detail action for {}").format(obj),
**self.admin_site.each_context(request),
},
)
Template displaying the form. Please note that breadcrumbs are empty in this case but if you want, you can configure your own breadcrumbs path.
