Forms not showing up when using a registration app

I'm using this app to register the user of my website https://github.com/egorsmkv/simple-django-login-and-register. The problem is that no metter what I do my form are not visible (they were when I did not use this registration app and the code worked just fine). This is my code:
model
class UserBio(models.Model):
name = models.CharField(max_length=120)
age = models.CharField(max_length=2)
phone = models.CharField(max_length=10)
height = models.CharField(max_length=3)
weight = models.CharField(max_length=3)
form
class UserBio(forms.ModelForm):
class Meta:
model = UserBio
fields = (name', 'age', 'phone', 'height', 'weight')
views
def add_bio(request):
submitted = False
if request.method == "POST":
info_form = UserBio(request.POST)
if info_form.is_valid():
info_form.save()
return HttpResponseRedirect('add_information?submitted=True')
else:
info_form = UserBio()
if 'submitted' in request.GET:
submitted = True
return render(request, 'accounts/profile/add_information.html', {'form': info_form, 'submitted':submitted})
urls
urlpatterns = [
path('add/information', views.add_information, name='add_information'),
]
html
{% extends 'layouts/default/base.html' %}
{% block title %} Add info {% endblock %}
{% load i18n %}
{% block content %}
<h4>{% trans 'Add Info' %}</h4>
{% if submitted %}
Sumitted correctly
{% else %}
<form method="post">
{% csrf_token %}
{{ info_form.as_p }}
</form>
</div>
<br/>
</body>
{% endif %}
{% endblock %}
Any help would be very apprecieted!

because in your views def add_bio change your url acc to your function views
path('add/information', views.add_bio, name='add_information'),
and in you template
{{ form.as_p }}

You passed the info_form variable to the template with variable name form. Indeed:
# name of the variable for the template ↓
return render(request, 'accounts/profile/add_information.html', {'form': info_form, 'submitted':submitted})
This thus means that you render this with:
{{ form.as_p }}
You should also trigger the correct view:
urlpatterns = [
path('add/information/', views.add_bio, name='add_information'),
]
The path does not point to the template: a path points to a view, and the view can (this is not required) render zero, one or multiple templates to create a HTTP response.

Rendering Issue with Include template tag and forms

Disclaimer: I am aware of several other posts that raise my issue, but they do not apply to my code.
Hi everyone, I am creating a knockoff of stackoverflow using Django, and I came into an issue.
I have a View that shows a question that has been asked. Obviously, anyone coming to that question should be able to answer it. Here are the views and templates:
This view displays the question and some other info:
class QuestionsDetailView(DetailView):
model = Question
template_name = "function/questions/questions_detail.html"
def get_context_data(self, *args, **kwargs):
context = {}
question_detail = Question.objects.filter(id=self.kwargs.get("pk")).first()
answers = Answer.objects.filter(question=question_detail)
context["question"] = question_detail
context["questioncomments"] = QuestionComment.objects.filter(question=question_detail)
context["answers"] = [[answer, AnswerComment.objects.filter(answer=answer)] for answer in answers]
return context
This view allows you to answer:
class AnswersCreateView(LoginRequiredMixin, CreateView):
model = Answer
fields = ["content"]
template_name = "function/answers/answers_create.html"
def form_valid(self, form):
form.instance.author = self.request.user
return super().form_valid(form)
def get_success_url(self):
return reverse("function-questions-detail", kwargs={"pk": self.kwargs.get("pk")})
On stackoverflow, when you view a question, you can answer it by scrolling down and providing your answer. I wanted to do something similar, so instead of having the answer view on a separate page, I put in in the question detail page using the 'include' template tag. Here are the templates:
This is the template for the question (which contains the include statement (bottom)):
{% extends 'core/base.html' %}
{% block content %}
<!--Question-->
<h1>{{ question.title }} by {{ question.author }}</h1>
{% if user == question.author %}
Update
Delete
{% endif %}
<h3>{{ question.content }}</h3>
<!--QuestionComments-->
{% for comment in questioncomments %}
<h6>{{ comment }} -- {{ comment.author }}</h6>
{% endfor %}
<!--Answers-->
{% if answers %}
{% for pair in answers %}
<!--Answers-->
<h3>{{ pair.0.content }}</h3>
<h5>{{ pair.0.author }}</h5>
<!--AnswerComments-->
{% for comment in pair.1 %}
<h6>{{ comment }}</h6>
{% endfor %}
{% endfor %}
{% endif %}
{% include 'function/answers/answers_create.html' %}
{% endblock content %}
Here is the template for the form which allows you to create an answer (this is the template that is referenced by the include template tag):
{% load crispy_forms_tags %}
<form method="POST">
{% csrf_token %}
<h2>Your Answer</h2>
{{ form|crispy }}
<button type="submit">Submit</button>
</form>
When I tried it out on the website in a browser, the question was rendering but the answer form was rendering everything except the form fields. It is rendering 'Your Answer' and the submit button but it is not rendering the actual field.
When I press submit I get the following error in my command prompt:
Method Not Allowed (POST): /questions/3/
Method Not Allowed: /questions/3/
So, in actual fact, the problem is how do I render the form properly. And will that solve the issue?
Thanks in advance.

Use form and pass it through context in your DetailView.
#form
class AnswerCreateForm(forms.ModelForm):
class Meta:
fields = ['content']
#views
class QuestionsDetailView(DetailView):
.......
def get_context_data(self, *args, **kwargs):
......
context['form'] = AnswerCreateForm()
return context
# create view
# provide same template name as the detail view.
class AnswersCreateView(LoginRequiredMixin, CreateView):
model = Answer
form_class = AnswerCreateForm
template_name = "function/questions/question_detail.html"

python crash course 19-1 edit posts not working

This is the error I get when clicking on Edit post under any one of the posts. Would appreciate any help as all this django stuff is confusing me but trying my best to learn. My new post function works and clicking blog/posts to go to the overview page for the blog or to look at all the posts works as well.

The issue is with this line in edit_post.html:
<p>{{ post }}</p>
If you are editing the post with id 1, then this link is to the url /posts/1. But that has no match in your urls.py file.
Either you need to remove the post.id parameter from the link, or create a view and a corresponding path in urls.py for this link.

Django NoReverseMatch Error during Template Rendering

I am setting up a simple blog site with Django, and run into this error when trying to link to a page that allows users to edit existing blog posts.
Reverse for 'edit_post' with arguments '('',)' not found. 1 pattern(s) tried: ['edit_post/(?P<title_id>[0-9]+)/$']
If I understand this error correctly, it means that Django can't find a urlpattern that matches the url being requested. To my eyes I have the urlpattern set up correctly, but I still get the error.
The link in question appears on the text.html template, which is the template that displays the text of a particular blog post.
Here is the relevant code:
urls.py
"""Defines URL patterns for blogs."""
from django.urls import path
from . import views
app_name = 'blogs'
urlpatterns = [
# Home page, shows all posts in chronological order.
path('', views.index, name='index'),

path('text/<int:title_id>/', views.text, name='text'),
# Page for adding a new post.
path('new_post/', views.new_post, name='new_post'),
# Page for editing a post.
path('edit_post/<int:title_id>/', views.edit_post, name='edit_post'),
]

edit_post.html (this page should display the existing post and allow it to be edited)
{% extends "blogs/base.html" %}
{% block content %}
<p>Edit post:</p>
<p>Title:</p>
<form action="{% url 'blogs:edit_post' title.id %}" method='post'>
{% csrf_token %}
{{ form.as_p }}
<button name="submit">Save changes</button>
</form>
{% endblock content %}
How the edit_post function in views.py should work (in theory) is to create an instance based upon the post's title id, and then allowing the user to edit it and save changes.
I'm not sure where I'm going wrong here and any suggestions are greatly appreciated.

The name of the post object you pass to the template, is not title, but post:
{% extends "blogs/base.html" %}
{% block content %}
<p>Edit post:</p>
<p>Title:</p>
<form action="{% url 'blogs:edit_post' post.pk %}" method='post'>
{% csrf_token %}
{{ form.as_p }}
<button name="submit">Save changes</button>
</form>
{% endblock content %}
If you use title.id, it will not find that variable, and thus this will be resolved to the empty string. If you use post.id, or post.pk, it will resolve to the .id field, or primary key of the post object.

django - What does this line achieve here?

I'm following a tutorial on effectivedjango.com, and this is the code they have:
views.py:
class CreateContactView(CreateView):
model = Contact
template_name = 'edit_contact.html'
fields = '__all__' #this is needed for error msg Using ModelFormMixin (base class of CreateContactView) without the 'fields' attribute is prohibited.
def get_success_url(self):
return reverse('contacts-list')
def get_context_data(self, **kwargs):
context = super(CreateContactView, self).get_context_data(**kwargs)
context['action'] = reverse('contacts-new')
return context
class UpdateContactView(UpdateView):
model = Contact
template_name = 'edit_contact.html'
fields = '__all__'
def get_success_url(self):
return reverse('contacts-list')
def get_context_data(self, **kwargs):
context = super(UpdateContactView, self).get_context_data(**kwargs)
context['action'] = reverse('contacts-edit', kwargs={'pk' : self.get_object().id})
return context
urls.py:
url(r'^$', contacts.views.ListContactView.as_view(),
name='contacts-list',),
url(r'^new$', contacts.views.CreateContactView.as_view(),
name='contacts-new',),
url(r'^edit/(?P<pk>\d+)/$', contacts.views.UpdateContactView.as_view(),
name='contacts-edit',),
contact_list.html:
{% block content %}
<h1>Contacts</h1>
<ul>
{% for contact in object_list %}
<li class="contact">
{{ contact }}
(edit)
</li>
{% endfor %}
</ul>
Add contact
{% endblock %}
edit_contact.html:
{% block content %}
{% if contact.id %}
<h1>Edit Contact</h1>
{% else %}
<h1>Add Contact</h1>
{% endif %}
<form action="{{ action }}" method="POST">
{% csrf_token %}
<ul>
{{ form.as_ul }}
</ul>
<input id="save_contact" type="submit" value="Save" />
</form>
Back to list
{% if contact.id %}
Delete
{% endif %}
{% endblock %}
Why does the line context['action'] = reverse('contacts-edit', kwargs={'pk' : self.get_object().id}) in views.py look like its calling itself?
What I mean is, this action is called when the submit button is pressed in the contact-edit template, correct? So it starts there, and it is reverse-calling contact-edit which is itself, right?
What am I not seeing here?
Thank you for all your help.

Yes, the line context['action'] = reverse('contacts-edit', kwargs={'pk' : self.get_object().id}) in views.py is calling itself. This line generates the proper url for contacts-edit view.
This is done so that POST requests come to the same view i.e. UpdateContactView which is an UpdateView. There, proper handling will be done i.e. form validation will occur with the sent data. If the form is valid, object will be updated. Otherwise, the form will be displayed again with errors.
Django docs on UpdateView:
A view that displays a form for editing an existing object,
redisplaying the form with validation errors (if there are any) and
saving changes to the object.
