How to create a simple confirmation view on Django Admin like the default delete view works
from django import forms
from django.contrib import admin
from django.template.response import TemplateResponse
class RegularCreationAdminForm(forms.ModelForm):
class Meta:
model = ReactivationCoupon
fields = [
'field1', 'field2', 'field3', 'field4',
'field5', 'field6',
]
class RegularCreateViewAdmin(admin.ModelAdmin):
list_display = ('field1', 'field2', 'field3', 'field4', 'field5', 'field6')
search_fields = ('field1',)
ordering = ('field1', 'field2',)
form = RegularCreationAdminForm
def _changeform_view(self, request, object_id, form_url, extra_context):
if request.method == 'POST' and "_confirmation" in request.POST and not object_id:
ModelForm = self.get_form(request)
form = ModelForm(request.POST, request.FILES)
form_validated = form.is_valid()
if form_validated:
new_object = form.save(commit=False)
context = {
**self.admin_site.each_context(request),
'obj': new_object,
'opts': self.model._meta,
'form': form,
}
return TemplateResponse(
request, 'admin/app_name/model_name/form_confirmation.html', context)
return super()._changeform_view(request, object_id, form_url, extra_context)
{% extends "admin/change_form.html" %}
{% block submit_buttons_bottom %}
<input type="submit" value="Confirm" name="_confirmation">
{% endblock %}
{% extends "admin/base_site.html" %}
{% load i18n l10n admin_urls %}
{% block bodyclass %}{{ block.super }} app-{{ opts.app_label }} model-{{ opts.model_name }} delete-confirmation
delete-selected-confirmation{% endblock %}
{% block breadcrumbs %}
<div class="breadcrumbs">
<a href="{% url 'admin:index' %}">{% trans 'Home' %}</a>
&rsaquo; <a href="{% url 'admin:app_list' app_label=opts.app_label %}">{{ opts.app_config.verbose_name }}</a>
&rsaquo; <a href="{% url opts|admin_urlname:'changelist' %}">{{ opts.verbose_name_plural|capfirst }}</a>
&rsaquo; {{ title }}
</div>
{% endblock %}
{% block content %}
<ul style="padding: 0">
This is a confirmation view!
</ul>
<hr>
<br>
<form action="" method="post">{% csrf_token %}
<div class="submit-row">
<input type="submit" name="_save" value="{% trans "Yes, do it!" %}"/>
<a href="#" onclick="window.history.back(); return false;"

</div>
<fieldset class="module aligned" style="visibility: hidden;">

This doesn't work when I have inlines in my admin, it complains about missing management form when I try to confirm the save. Is there anyway I can make this work? Any help would be appreciated.

@JuneZho Yes, Django deals with inline formsets a bit different. I have modified the _changeform_view just for the simplest case. My advice to you is to use the full method available here, and only perform the redirect after the inline_instances are created. Let me know if this is useful to you

Thank you for your help on customizing _changeform_view to have confirmation page. I also had problem with inline formsets and figured out a way to deal with it by adding this to context:
formsets, _ = self._create_formsets(request, attribute, change=True)
Then, next thing to do is rendering all formsets in template:
{% for formset in formsets %}
{{ formset }}
{% endfor %}

If we want confirmation for a single admin model..is there a way to make it work?
