models.py
from django.db import models
# Create your models here.
CHOOSE =[
('Usual','Обычный тариф'),
('Premium','Премиум тариф'),
('Prise','Аукционный')
]
class VDSTARIFS( models.Model):
id = models.CharField(max_length=40, primary_key= True,serialize=True)
name = models.CharField(max_length=20, verbose_name = 'Цены')
choosen = models.CharField(max_length= 20, choices = CHOOSE, verbose_name = 'Тариф', help_text='Выбор тарифного плана.')
title = models.CharField(max_length= 15)
def __str__(self):
return str(self.title)
class blog(models.Model):
id = models.CharField(max_length=40, primary_key= True,serialize=True)
message = models.TextField( verbose_name= 'Сообщение блога')
titleblog = models.CharField(max_length=50, verbose_name = 'Название')
img = models.ImageField(upload_to = 'admin/', verbose_name= 'Картинка' )
def __str__(self):
return str(self.titleblog)
def get_all_objects(self): ##maybe I have troubles with it.
queryset = self.__class__.objects.all()
blog.html
{% csrftoken %}
{% for item in message %}
{% endfor %}
views.py
from django.shortcuts import render
from django.http import HttpResponse
from django.shortcuts import render

urls.py
from django.contrib import admin
from django.urls import path
from polls import views
from django.conf import settings
from django.conf.urls.static import static
urlpatterns = [
path('admin/', admin.site.urls),
path('', views.index_view, name='home'),
path('vds', views.vds, name='vds' ),
path('minecraft', views.minecraft, name='minecraft' ),
path('about', views.about, name='about'),
path('blog', views.blog, name='blog')
]

Answer 1

The actual error is probably caused by the wrong url pattern:
path('blog', views.blog, name='blog')
views.blog refers to the blog model due to:
from polls.models import blog
What you need here is the view not the model, so:
path('blog', views.messagesblog, name='blog')
Then, remove the "self" argument from your messagesblog function.
Use the "render" function from django.shortcuts and provide a context with the blog objects:
def messagesblog(request):
return render(request, "blog.html", {message: blog.objects.all()})
That might solve your problem.
Still, there are some things you could improve.
E.g.: Don't use "id" fields in your model definitions if you don't really, really have to, as this is usually an auto-generated number (BigInt) field.
That's only one tip from an old Django veteran happy to be finally heard. You'll find out much more yourself as you proceed.
