When i fill the income from admin panel on model page everthing works. Don't know how to make it work from main page.
Here is my view (second form that i added is b_form, a_form is working):

a_form.save()

Django change password link is not active?

I am learning an authentication in Django. Today I am stuck with this problem and I am not able to figure out how can I solve it. I want to make a form for password change. but the change form link is not active and I don't know how to fix it.
here is my views.py
#login_required
def user_change(request):
current_user = request.user
form = UserProfileChange(instance = current_user)
if request.method == 'POST':
form = UserProfileChange(request.POST,instance = current_user)
if form.is_valid():
form.save()
form = UserProfileChange(instance = current_user)
form = UserProfileChange(instance = current_user)
return render(request, 'App_Login/change_profile.html', context={'form':form})
#login_required
def pass_change(request):
current_user = request.user
form = PasswordChangeForm(current_user)
if request.method == 'POST':
form = PasswordChangeForm(current_user, data = request.POST)
if form.is_valid():
form.save()
return render(request, 'App_login/pass_change.html', context = {'form':form})
here is urls.py file
from django.urls import path
from . import views
app_name = 'App_Login'
urlpatterns = [
path('signup/', views.signup, name = "signup"),
path('signin/', views.login_page, name = 'signin'),
path('logout/' , views.logout_user, name = "logout" ),
path('profile/' , views.profile, name = "profile" ),
path('change-profile/' , views.user_change, name = "user_change" ),
path('password/' , views.pass_change, name = "pass_change" ),
]
here is change_profile.html
{% extends 'base.html' %}
{% load crispy_forms_tags %}
{% block title %} change User profile {% endblock %}
{% block body_block %}
<h2>Change Profile</h2>
<form method="post">
{% csrf_token %}
{{form|crispy}}
<input type="submit" value="Change" class = "btn btn-primary btn-sm">
</form>
{% endblock %}
here is forms.py file
from django import forms
from django.contrib.auth.forms import UserCreationForm, UserChangeForm
from django.contrib.auth.models import User
class SignupForm(UserCreationForm):
email = forms.EmailField(label = "Email Address", required=True)
class Meta:
model = User
fields = ('username','email', 'password1', 'password2')
class UserProfileChange(UserChangeForm):
class Meta:
model = User
fields = ('username','email','first_name', 'last_name', 'password')

Django has an inbuilt functionality to do that in your urls file modify it to according your needs
from django.contrib.auth import views as auth_views
urlpatterns = [
#
# Rest Of Your Code
#
path('password/',auth_views.PasswordChangeView.as_view(
template_name='template to render here',
success_url = 'page to redirect after password is changed'),name='password')
]

Django showing percentage of task completed/total task

I'm trying to make a simple django app which is like a todo app, I want to add the percentage of task completed.
Here's my model.py
from django.db import models
from django.urls import reverse
class Task(models.Model):
title = models.CharField(max_length=200)
create_time = models.DateTimeField(auto_now_add=True)
complete_time = models.DateTimeField(blank=True, null=True)
status = models.BooleanField(default=False)
def __str__(self):
return self.title
and here's the template file
<form method="POST" action="/">
{% csrf_token %}
{{form}}
<input class="btn submit" type="submit" name="save">
</form>
{% for task in tasks %}
{% if task.status == True %}
<strike>{{task}}, {{task.complete_time}}</strike>
{% else %}
{% endif %}
{% endfor %}
and this is views.py file
def list(request):
queryset = Task.objects.order_by('complete_time','complete_time')
if request.method =='POST':
form = TaskForm(request.POST)
if form.is_valid():
form.save()
return redirect('/')
context = {
'tasks':queryset,
'form':form,
}
return render(request, 'tasklist.html', context)

use a class-based view
in views.py
from django.views.generic.list import ListView
class list(ListView):
model = Task
template_name = 'tasl_list.html'
def get_context_data(self, *args, **kwargs):
context = super().get_context_data(**kwargs)
context['get_percentage_done'] = Task.objects.filter(status = True).count() * 100 / Task.objects.all().count()
return context
in your template
{{get_percentage_done}}

Django edit comment

So i want to do a edit existing comment, but it gives me this error
ValueError at /episode/Dragon-Ball-Super/edit/11
The view home.views.edit_comment didn't return an HttpResponse object. It returned None instead.
edit_comment
def edit_comment(request, slug, id):
anime = get_object_or_404(Anime, slug=slug)
comment = get_object_or_404(Comment, id=id)
form = CommentForm(request.POST, instance=comment.user)
if request.method == 'POST' or 'NONE':
if form.is_valid():
form.save()
return redirect('anime_title', slug=slug)
else:
form = CommentForm()
context = {'form': form}
return render(request, 'home/edit-comment.html', context)
urls.py
urlpatterns = [
path('', views.index, name='index'),
re_path(r'^episode/(?P<slug>[\w-]+)/$', views.anime_title, name='anime_title'),
re_path(r'^episode/(?P<slug>[\w-]+)/comment/$', views.add_comment, name='add_comment'),
re_path(r'^episode/(?P<slug>[\w-]+)/edit/(?P<id>\d+)/?', views.edit_comment, name='edit_comment'),
]
link under existing comment
{% if comment.user == request.user.userprofile %}
<h6 class="small comment-meta">
Edit
Delete</h6>
{% endif %}
models.py
class Comment(models.Model):
anime = models.ForeignKey(Anime, on_delete=models.CASCADE)
user = models.ForeignKey(UserProfile, on_delete=models.CASCADE)
body = models.TextField()
created = models.DateTimeField(auto_now_add=True)
edit-comment.html
{% extends 'base/base.html' %}
{% block head %}
<title>Edit Comment</title>
{% endblock %}
{% block content %}
<h2>Edit Comment</h2>
<form method="POST">
{% csrf_token %}
{{ form.as_p }}
<button type="submit">Submit</button>
</form>
{% endblock %}

You are handling only the POST request. GET request will be placed the first time when you load the form.
def edit_comment(request, slug, id):
anime = get_object_or_404(Anime, slug=slug)
comment = get_object_or_404(Comment, id=id)
form = CommentForm()
if request.method == 'POST':
form = CommentForm(request.POST, instance=comment.user)
if form.is_valid():
form.save()
return redirect('anime_title', slug=slug)
return render(request, 'home/edit-comment.html', {'form':form})

Take In Input from User and Display the same input on the same page

Hi i am trying to create a post form in django where the user creates a post and the post is displayed back to them on the same page so far i have been unsuccessful. My articles display on the page but the form to post articles doesnt only the submit button shows.
views.py
def articles(request):
args = {}
args.update(csrf(request))
args ['posts'] = post.objects.filter(user = request.user)
args ['full_name'] = User.objects.get(username = request.user.username)
return render_to_response('articles.html', args)
def article(request, post_id=1):
return render(request, 'article.html',
{'post': post.objects.get(id=post_id) })
def create(request):
if request.POST:
form = PostForm(request.POST, request.FILES)
if form.is_valid():
a = form.save(commit=False)
a.user = User.objects.get(username = request.user.username)
a.save()
messages.add_message(request, messages.SUCCESS, "You Article was added")
return HttpResponseRedirect('/posts/all')
else:
form = PostForm()
args = {}
args.update(csrf(request))
args['form'] = form
return render_to_response('articles.html', args)
articles.html
<form action="/posts/create/" method="post" enctype="multipart/form-data">{% csrf_token %}
<ul>
{{form.as_ul}}
</ul>
<input type="submit" name="submit" value="Create Article">
</form>
{% if posts.count > 0 %}
{% for post in posts %}
<div>
<h2>{{full_name}}</h2>
<p>{{ post.body|lower|truncatewords:50 }}</p>
<p>{{post.likes}} people liked this article</a></p>
</div>
{% endfor %}
{% else %}
<p>None to show!</p>
{% endif %}
{% endblock %}
urls.py
from django.conf.urls import patterns, include, url
urlpatterns = patterns('',
url(r'^create/$', 'posts.views.articles'),
url(r'^get/(?P<post_id>\d+)/$', 'posts.views.article'),
url(r'^create/$', 'posts.views.create'),
url(r'^like/(?P<post_id>\d+)/$', 'posts.views.like_article'),
url(r'^article/(?P<post_id>\d+)/$', 'posts.views.add_comment'),
)

First off you aren't passing the form to the template in articles(). You need to have something along the lines of:
args['form'] = YourForm()
In your first view function. Also, in your create view you do this:
a.user = User.objects.get(username = request.user.username)
Which does an unnecessary database lookup of the user again, you can just do this to be clearer and faster:
a.user = request.user
