UpdateWithInlinesView for django-extra-views not working with crispy_forms

I have a Django app with django-extra-views to create and maintain a pair of related models. The set up is as follows:
# models.py
class ModelA(models.Model):
# fields
def get_absolute_url(self):
return reverse('model_a:detail', kwargs={'pk': self.id})
class ModelB(models.Model):
model_a = models.OneToOneField(ModelA, on_delete=models.CASCADE)
# other fields
I have two corresponding views and forms:
# views.py
class ModelBView(InlineFormSetFactory):
model = ModelB
form_class = ModelBForm
prefix = 'model_b'
class ModelACreateView(LoginRequiredMixin, PermissionRequiredMixin, CreateWithInlinesView):
model = ModelA
inlines = [ModelBView, ]
permission_required = ('add_model_a')
template_name = 'apps/model_a/create.html'
form = ModelAForm
fields = '__all__'
def get_success_url(self):
return self.object.get_absolute_url()
class ModelAUpdateView(LoginRequiredMixin, PermissionRequiredMixin, UpdateWithInlinesView):
model = ModelA
inlines = [ModelBView, ]
permission_required = ('change_model_a')
template_name = 'apps/model_a/update.html'
form = ModelAForm
fields = '__all__'
def get_success_url(self):
return self.object.get_absolute_url()
# forms.py
class ModelAForm(forms.ModelForm):
class Meta:
model = ModelA
fields = [
# some fields
]
initial = [...]
class ModelBForm(forms.ModelForm):
class Meta:
model = ModelB
fields = [
# some fields
]
The trouble happens in the template files. The CreateWithInlinesView works, while UpdateWithInlinesView does not, when paired with crispy_forms. Following is the code that DOES NOT work. When I press the 'Save' button, it brings me back to the update page and when I check the details page, things are unchanged:
<form class="form-horizontal" method="POST">
{% csrf_token %}
<div class="form-row">
<div class="form-group col-md-8 mb-0">
{{ form.name|as_crispy_field }}
</div>
<div class="form-group col-md-4 mb-0">
{{ form.phone|as_crispy_field }}
</div>
</div>
{% for formset in inlines %} {% for addr in formset %}
<div class="form-row">
<div class="form-group col-md-6 mb-0">
{{ addr.field_1|as_crispy_field }}
</div>
<div class="form-group col-md-6 mb-0">
{{ addr.field_2|as_crispy_field }}
</div>
</div>
{% endfor %} {{ formset.management_form }} {% endfor %}
<div class="control-group text-right">
<div class="controls">
<button type="submit" class="btn btn-default btn-person"><i class="fas fa-save"></i> Save</button>
</div>
</div>
</form>
There is a version that DOES WORK. But it involves me not using crispy_forms and is aesthically unappealing. When I press the 'Save' button, it updates and redirects to the "details" page. Below is the code (the difference is the bottom half):
<form class="form-horizontal" method="POST">
{% csrf_token %}
<div class="form-row">
<div class="form-group col-md-8 mb-0">
{{ form.name|as_crispy_field }}
</div>
<div class="form-group col-md-4 mb-0">
{{ form.phone|as_crispy_field }}
</div>
</div>
{% for formset in inlines %} {{ formset }} {% endfor %}
<div class="control-group text-right">
<div class="controls">
<button type="submit" class="btn btn-default btn-person"><i class="fas fa-save"></i> Save</button>
</div>
</div>
</form>
I don't know how to proceed on this one and would love someone's help. Thank you.

This is basically happening because you didn't include id (hidden field) in the formset.
To check error you can write the below method in UpdateWithInlinesView.
def forms_invalid(self, form, inlines):
for formset in inlines:
for errors in formset.errors:
for _, error in errors.items():
print(error[0])
return self.render_to_response(
self.get_context_data(request=self.request, form=form, inlines=inlines))
This will print
id: 'This field is required'
To get rid of this, you have to include hidden fields as follows:
{% for formset in inlines %}
{{ formset.management_form|crispy }}
{{ formset|as_crispy_errors }}
{% for addr in formset %}
{% for hidden in addr.hidden_fields %}
{{ hidden }}
{% endfor %}
<div class="form-row">
<div class="form-group col-md-6 mb-0">
{{ addr.field_1|as_crispy_field }}
</div>
<div class="form-group col-md-6 mb-0">
{{ addr.field_2|as_crispy_field }}
</div>
</div>
{% endfor %}
{% endfor %}
Or you can try below one also. In this we are directly passing the id field (hidden by default). I am using this one
{% for formset in inlines %}
{{ formset.management_form|crispy }}
{{ formset|as_crispy_errors }}
{% for addr in formset %}
{{ addr.id }}
<div class="form-row">
<div class="form-group col-md-6 mb-0">
{{ addr.field_1|as_crispy_field }}
</div>
<div class="form-group col-md-6 mb-0">
{{ addr.field_2|as_crispy_field }}
</div>
</div>
{% endfor %}
{% endfor %}

Django error: 'WSGIRequest' object has no attribute 'post' for comments

I'm new to django and I'm working on a blog app and trying to enable comments for posts. When I write comments from admin page everthing works fine, but as a user I get following error: 'WSGIRequest' object has no attribute 'post'. Searching similar problems I see that mostly people switch request.Post for request.POST but I do not have that in my code, I wrote view for comment as a class not as def comment(request)… How do I solve this problem?
code from views.py:
class PostDetailView(DetailView):
model = Post
class PostCreateView(LoginRequiredMixin, CreateView):
model = Post
fields = [title, summary, content, image]
def form_valid(self, form):
form.instance.author= self.request.user
return super().form_valid(form)
class CommentCreateView(LoginRequiredMixin, CreateView):
model = Comment
fields = ['content']
def form_valid(self, form):
form.instance.user = self.request.user
form.instance.post = self.request.post
return super().form_valid(form)
code from models.py:
class Comment(models.Model):
post = models.ForeignKey(Post, related_name='comments', on_delete=models.CASCADE)
user = models.ForeignKey(User, on_delete=models.CASCADE)

created = models.DateTimeField(auto_now_add=True)
class Meta:
ordering = ['created']
def save(self, *args, **kwargs):
super().save(*args, **kwargs)
def __str__(self):
return 'Comment of user {}: {}'.format(self.user, self.content)
class Post(models.Model):
title= models.CharField(max_length=100)
summary= models.TextField(max_length=200, default='defalut text ...')
content= models.TextField()

author = models.ForeignKey(User, on_delete=models.CASCADE)
def save(self, *args, **kwargs):
super().save(*args, **kwargs)
img = Image.open(self.image.path)
img.save(self.image.path)
def __str__(self):
return self.title
def get_absolute_url(self):
return reverse('post-detail', kwargs={'pk': self.pk})
from post_detail.html:
{% extends "recepti/base.html" %}

code from urls.py:
urlpatterns = [
path('', PostListView.as_view(), name='recepti-home'),
path('user/<str:username>', UserPostListView.as_view(), name='user-posts'),

path('post/new/', PostCreateView.as_view(), name='post-create'),

path('post/comment/', CommentCreateView.as_view(), name='post-comment'),
path('about/', views.about, name='recepti-about')
]
code from comment_form.html:
{% extends "recepti/base.html" %}
{% load crispy_forms_tags %}
{% block content %}
<div class="content-section">
<form method="POST">
{% csrf_token %}
<fieldset class="form-group">
<legend class="border-bottom mb-4">New comment</legend>
{{ form|crispy }}
</fieldset>
<div class="form-group">
<button class="btn btn-outline-info" type="submit">Submit</button>
</div>
</form>
</div>
{% endblock content %}

I guess the "post" is related to Comment.post not to the method you are using.
So Comment consists of 4 fields (one of them is autofield) but you listed only 'comment' in your fields - add other fields or use modelform

There are couple of little issues here; First, you need a way to specify the post which is going to have the comment in some way. You can use the primary key of post for that purpose. So you need to change the url like:
urls.py:
path('post/<int:post_pk>/comment/', CommentCreateView.as_view(), name='post-comment'),
and change the action attribute of the form as well:
template:
{% extends "recepti/base.html" %}
{% load crispy_forms_tags %}
{% block content %}
<div class="content-section">
<form method="POST" action="{% url 'post-comment' object.pk %}"> <-------------
{% csrf_token %}
<fieldset class="form-group">
<legend class="border-bottom mb-4">New comment</legend>
{{ form|crispy }}
</fieldset>
<div class="form-group">
<button class="btn btn-outline-info" type="submit">Submit</button>
</div>
</form>
</div>
{% endblock content %}
(based on the approach you used to render this template, you may need to replace post.pk with object.pk or something similar)
and finally, in the views.py, you can access the primary key of the post using self.kwargs:
class CommentCreateView(LoginRequiredMixin, CreateView):
model = Comment
fields = ['content']
def form_valid(self, form):
form.instance.user = self.request.user
form.instance.post = self.kwargs.get('post_pk')
return super().form_valid(form)

How to add extra category field in django.views.generic

I have class in views.py:
class PostCreateView(LoginRequiredMixin, CreateView):
model = Post
fields = ['title', 'content',]
def form_valid(self, form):
form.instance.author = self.request.user
return super().form_valid(form)
I want to add object to fields, but when I'm trying to add like this:
fields = ['title', 'content', 'category']
the debugger send an error log like this:
FieldError at /post/new/
Unknown field(s) (category) specified for Post
I need an extra column to add category field when creating post in my django blog.
Here is blog_category.html
{% extends 'blog/base.html' %}
{% block content %}
<h1 class='mb-3'>Category: {{ category | title }}</h1>
{% for post in posts %}
<article class="media content-section">
<img class="rounded-circle article-img" src="{{ post.author.profile.image.url }}" alt="">
<div class="media-body">
<div class="article-metadata">
<a class="mr-2 author_title" href="{% url 'user-posts' post.author.username %}">#{{ post.author }}</a>
<small class="text-muted">{{ post.date_posted|date:"N d, Y" }}</small>
<div>
<small class="text-muted">
Categories:
{% for category in post.categories.all %}
<a href="{% url 'blog_category' category.name %}">
{{ category.name }}
</a>
{% endfor %}
</small>
</div>
</div>
<h2><a class="article-title" href="{% url 'post-detail' post.id %}">{{ post.title }}</a></h2>
<p class="article-content">{{ post.content|slice:200 }}...</p>
</div>
</article>
{% endfor %}
{% endblock content %}
models.py:
from django.db import models
from django.utils import timezone
from django.contrib.auth.models import User
from django.urls import reverse
class Post(models.Model):
title = models.CharField(max_length=200)
content = models.TextField()
date_posted = models.DateTimeField(default=timezone.now)
author = models.ForeignKey(User, on_delete=models.CASCADE)
categories = models.ManyToManyField('Category', related_name='posts')
image = models.ImageField(upload_to='images', default="images/None/no-img.jpg")
def __str__(self):
return self.title
def get_absolute_url(self):
return reverse('post-detail', kwargs={'pk': self.pk})
class Category(models.Model):
name = models.CharField(max_length=20)
My post_form.html:
{% extends 'blog/base.html' %}
{% load crispy_forms_tags %}
{% block content %}
<div class="content-section">
<form method="POST">
{% csrf_token %}
<fieldset class="form-group">
<legend class="border-bottom mb-4">Blog Post</legend>
{{ form|crispy }}
</fieldset>
<div class="form-group">
<button class="btn btn-outline-info" type="submit">Post</button>
</div>
</form>
</div>
{% endblock content %}
The main goal is:
create category field in views.py -> after pressing "Post" this field should push the content to the django admin panel and add category to the post(as title and content adding).
If someone have a ready solution or know how to solve this problem, I would be really happy.

fields = ['title', 'content', 'categories']

Django form action

I just started with Django and already scratching my head, I have a simple form with action set to null, On submit it goes to a url which I cannot find since I have to put a condition there as to which url should it hit.
template:
{% extends 'base.html' %}
{% block body_block %}
<div class="container">
<div class="">
<h2>Education Details</h2>
<form action="" method="post">
{{ form.as_p }}
{% csrf_token %}
<div class="d-flex justify-content-end">
{% if '/attorney-profile-wizard/additional-information/' not in request.META.HTTP_REFERER %}
<a href="{% url "attorney_edit" url_key %}"
class="material-button bg-red pl-2">Cancel</a>
{% else%}
<a href="/attorney-profile-wizard/additional-information/"
class="material-button bg-red pl-2">Cancel</a>
{% endif %}
<!--<a href="{% url "attorney_edit" url_key %}"-->
<!--class="material-button bg-red pl-2">Cancel</a>-->
<input type="submit" class="material-button" name="" value="Save Education">
</div>
</form>
</div>
</div>
{% endblock %}
Model:
class Education(models.Model):
degree = models.CharField(max_length=256)
school_name = models.CharField(max_length=256)
accolades = models.TextField(null=True)
start_year = models.IntegerField(blank=True, null=True)
end_year = models.IntegerField(blank=True, null=True)
is_law_school = models.BooleanField(default=False)
position = models.PositiveSmallIntegerField(blank=True, null=True)
attorney = models.ForeignKey(AttorneyProfile, related_name='educations')
created_at = models.DateTimeField(auto_now_add=True)
modified_at = models.DateTimeField(auto_now=True)
class Meta:
ordering = ['-id']
def __str__(self):
return '{} - {}'.format(self.attorney, self.degree)
views.py
class AttorneyEducationEditMixin(AttorneyEducationMixin, AttorneyEditMixin):
form_class = EducationForm
template_name = 'attorney/education/form.html'
class EducationCreateView(AttorneyEducationEditMixin, CreateView):
permission_required = 'educations.add_education'
class EducationUpdateView(AttorneyEducationEditMixin, EducationPermissionMixin,
UpdateView):
permission_required = 'educations.change_education'
class EducationDeleteView(AttorneyEducationMixin, EducationPermissionMixin,
DeleteView):
template_name = "attorney/shared/title_delete.html"
permission_required = 'educations.delete_education'
I even tried to override the form action trying the following way:
{% if '/attorney-profile-wizard/additional-information/' not in request.META.HTTP_REFERER %}
<form action="{% url "attorney_edit" url_key %}" method="post">
{% else %}
<form action="/attorney-profile-wizard/additional-information/" method="post">
{% endif %}
{{ form.as_p }}
{% csrf_token %}
<div class="d-flex justify-content-end">
{% if '/attorney-profile-wizard/additional-information/' not in request.META.HTTP_REFERER %}
<a href="{% url "attorney_edit" url_key %}"
class="material-button bg-red pl-2">Cancel</a>
{% else%}
<a href="/attorney-profile-wizard/additional-information/"
class="material-button bg-red pl-2">Cancel</a>
{% endif %}
<!--<a href="{% url "attorney_edit" url_key %}"-->
<!--class="material-button bg-red pl-2">Cancel</a>-->
<input type="submit" class="material-button" name="" value="Save Education">
</div>
</form>
This did not work and obviously is not the right way to do so. Where would I find the url for the action? I even checked urls.py file but it did not help much.

samuelcolvin's django-bootstrap3-datetimepicker not showing calendar when clicked on input field

I am trying to use samuelcolvin's django-bootstrap3-datetimepicker in which its based on Eonasdan's bootstrap-datetimepicker but forked from nkunihiko's django-bootstrap3-datetimepicker to show the calendar so the user can select the date and time and submit it. The issue I am having is that when I try to click on the field or on the right button with the calendar icon in it like in the demo website, it does not show me nothing.
I also had to add widgets.py from the repo into my project since it was giving me a No module named bootstrap3_datetime.widgets error.
Would appreciate your help
