message is not shown - python

I am making a web site by seeing Django tutorial.But message in results.html is not shown.
results.html is

<ul>
{% for choice in question.choice_set.all %}

{% endfor %}
</ul>
Vote again?

results.html inherits base.html.
base.html is

Why is my create button not redirecting to the form? (For django)

I am new to Django and am trying to make an online journal, and the server runs fine, but when I press the create button, it does not redirect to the form even though a POST request is being sent. screenshot of the create page. I'm not sure why.
This is the code:
views.py:
from django.shortcuts import render, redirect, get_object_or_404
from ejournal.models import Journal
from ejournal.forms import JournalForm
def make_entry(request):
if request.method == "POST":
entry = JournalForm(request.POST, request.FILES)
if entry.is_valid():
entry.save()
return redirect('list_journals')
else:
entry = JournalForm()
context = {
'entry':entry
}
return render(request, 'ejournal/create.html', context)
def delete_entry(request, id):
entry = get_object_or_404(Journal, id=id)
if request.method == "POST":
entry.delete()
return redirect('list_journals')
context = {
'object':object
}
return render(request, 'journal/delete.html',context)
def list_journals(request):
entries = Journal.objects.all()
context = {
'entries': entries
}
return render(request, 'ejournal/list_journals.html',context)
def journal_detail(request, id):
journal = Journal.objects.get(id=id)
context = {
'journal':journal
}
return render(request, 'journal/journal_detail.html', context)
forms.py
from ejournal.models import Journal
from django.forms import ModelForm
class JournalForm(ModelForm):
class Meta:
model = Journal
fields = ['name','title','text','image']
models.py
from django.db import models
class Journal(models.Model):
name = models.CharField(max_length=20)
title = models.CharField(max_length=50)
text = models.TextField(max_length=1000)
date = models.DateField(auto_now_add=True)
image = models.FileField(upload_to='')
archived = models.BooleanField(default=False)

urlpatterns = [

path('list_journals', list_journals, name="list_journals"),
path('delete/<int:id>/', delete_entry, name="delete_entry"),
path('journal_detail/<int:id>',journal_detail, name="journal_detail"),
]
You pass the form as the variable entry to your template ejournal/create.html.
Inside this template you use {{ form.as_p }}, but form is undefined. You need to use the variable entry because thats where the form is assigned to.
So your create.html becomes this:
{% extends 'ejournal/base.html' %}
{% block content %}
<div class="center_journal">
<h1> Create Journal Entry </h1>
</div>
<div class="center_journal">
<form method="POST" enctype="multipart/form-data">
{% csrf_token %}
<p>{{ entry.as_p }}</p>
<button class="btn btn-primary" type="submit">CREATE</button>
</form>
</div>
{% endblock content %}
You're checking if your form is valid by using entry.is_valid(), but your form will always be invalid because you didn't pass the correct form in your template, as described above.
Check with form's action='' attribute like this...
<form method="POST" action="{% url 'make_entry' %}" enctype="multipart/form-data">
{% csrf_token %}
<p>{{ form.as_p }}</p>
<button class="btn btn-primary" type="submit">CREATE</button>
</form>

Program not save and update new data in Django

I create program stock management system by using Django. Page of Update_items that create for saving and updating. Program can running but when I will update new data it can't save and update data. It will redirect with same data. I'm not sure whatit's wrong. I am very new so please introduce me.
This is from views.py
from email import header
from multiprocessing import context
from urllib import request
from django.shortcuts import render,redirect
import stockmgmt
from .models import Stock
from .forms import StocksearchForm,StockCreateForm,StockUpdateForm
def home(request):
title = 'ยินดีต้อนรับเข้าสู่ระบบสต็อคสินค้าเซียงกง'
form = 'Welcome: This is the Home Page'
context = {
"title": title,
"test": form,
}
return render(request, "home.html",context)
def list_items(request):
title = 'รายการสินค้า'
form = StocksearchForm(request.POST or None)
queryset = Stock.objects.all()
context = {
"title": title,
"queryset": queryset,
"form":form
}
if request.method == 'POST':
queryset = Stock.objects.filter(category__icontains=form['category'].value(),item_name__icontains=form['item_name'].value(),id_product__icontains=form['id_product'].value(),shop_name__icontains=form['shop_name'].value())
context ={
"form":form,
"header": header,
"queryset": queryset,
}
return render(request, "list_items.html",context)
def add_items(request):
form=StockCreateForm(request.POST or None)
if form.is_valid():
form.save()
return redirect('/list_items')
context={
"form":form,
"title":"Add Item",
}
return render(request,"add_items.html",context)
def update_items(request, pk):
queryset = Stock.objects.get(id=pk)
form = StockUpdateForm(instance=queryset)
if request.method == ' POST':
form = StockUpdateForm (request.POST, instance=queryset)
if form.is_valid():
form.save()
return redirect('/list_items')
context = {
'form':form
}
return render(request, 'add_items.html', context)

CSS is only applying on few html files and not rest

So i am building a personal website and am using Materialize for web designing. At first it was good and my pages look good, but then I added some new pages and i found that the css is not applied in these new pages, can anybody help me in solving this.
Actually both are same pages(categories.html) but the path are different.

According to the comment above, i changed my header.html,
<<!DOCTYPE html> <html> <head> <meta charset="utf-8">
<!--Import Google Icon Font-->
<link href="https://fonts.googleapis.com/icon?family=Material+Icons" rel="stylesheet">
<!--Import materialize.css-->
<link type="text/css" rel="stylesheet" href="/static/main/materialize.css" media="screen,projection"/>
</head>
<body>
{% load static %}
{% include "main/includes/navbar.html" %}
{% include "main/includes/messages.html" %}
<main>
<div style="background-image: url('https://www.google.com/url?sa=i&url=https%3A%2F%2Fwallpapersafari.com%2Fw%2FcU6JWo&psig=AOvVaw1eBAulQvnXOrIK1yQueVX5&ust=1623841457736000&source=images&cd=vfe&ved=0CAIQjRxqFwoTCPje9_--mfECFQAAAAAdAAAAABAD')">
<div class = "container">
<br>
{% block content %}
{% endblock %}
</div>
</div>
</main>
{% include "main/includes/footer.html" %}
<script type="text/javascript" src="/static/main/materialize.js"></script> </body> </html>
notice the href of css and js link tag.
There are a few things that I have seen here that don't look correct. Number 1, Are you inheriting your template from your base?
{% extends 'base.html' %}
This is where you should call your materialize.css (in the base template)
Load static is in the wrong place, you are calling static after the link to the css, load static should be at the very top of the template:
{% extends 'base.html' %} {% load static %}
You have an extra opening chevron in your DOCTYPE.
Put materialize js in you base template before closing body tag. Django by default inherits the default base template so this is what you could be missing.
In case I have misunderstood, and you are only wanting to call materialize.css for that header template you can use tags after the call for load static
{% block extra_css %}<link rel="stylesheet" href="{% static 'main/materialize.css' %}"> {% endblock extra_css %}
This might help:
{% load static %} above doctype tag!
{% load static %}
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<!--Import Google Icon Font-->
<link href="https://fonts.googleapis.com/icon?family=Material+Icons" rel="stylesheet">
<!--Import materialize.css-->
<link type="text/css" rel="stylesheet" href="{% static 'main/materialize.css' %}" media="screen,projection"/>
</head>
<body>
{% include "main/includes/navbar.html" %}
{% include "main/includes/messages.html" %}
<main>
<div style="background-image: url('https://www.google.com/url?sa=i&url=https%3A%2F%2Fwallpapersafari.com%2Fw%2FcU6JWo&psig=AOvVaw1eBAulQvnXOrIK1yQueVX5&ust=1623841457736000&source=images&cd=vfe&ved=0CAIQjRxqFwoTCPje9_--mfECFQAAAAAdAAAAABAD')">
<div class = "container">
<br>
{% block content %}
{% endblock %}
</div>
</div>
</main>
{% include "main/includes/footer.html" %}
<script type="text/javascript" src="{% static 'main/materialize.js' %}"></script>
</body>
</html>
In every html page {% load static %} below {% block content %} and above the html of the page!
Static files path:
{% static 'app name/filefoldername' %}
Hope you understood! Look for some tutorials on youtube also!

here is my note app page
Error that I getting
can anybody tell me where I made the mistake?
thanks in advance
Try replacing "{% url 'delete' things.id %}" with "{% url '<appname>:delete' things.id %}" the appname should be replaced by your app name. The same format works for me in Django 2.x.
