django.core.exceptions.FieldError: Unknown field(s) (model) specified for Post

These are the py files (error says unknown field(s) (model) specified for Post)

views.py

from django.db import models
from django.shortcuts import render
from django.views.generic import ListView, DetailView, CreateView
from .models import Post
from .forms import Post_form
# Create your views here.

#def home(request):
#    return render(request, 'home.html', {})

class HomeView(ListView):
    model = Post
    template_name = 'home.html'

class ArticleDetailView(DetailView):
    model = Post
    template_name = 'article_details.html'

class AddPostView(CreateView):
    model = Post
    form_class = Post_form
    template_name = 'add_post.html'
    #fields = '__all__'

forms.py

from django import forms
from django.forms import widgets, ModelForm
from django import forms
from .models import Post

class Post_form(forms.ModelForm):
    class Meta:
        model = Post
        fields = ('title','title_tag', 'model', 'body')
         
    widgets = {
        'title' : forms.TextInput(attrs={'class':'form-control'}),
        'title_tag' : forms.TextInput(attrs={'class':'form-control'}),
        'author' : forms.Select(attrs={'class':'form-control'}),
        'title' : forms.Textarea(attrs={'class':'form-control'})
    }

models.py

from typing import ChainMap
from django.db import models
from django.contrib.auth.models import User
from django.db.models.fields import CharField
from django.urls import reverse

# Create your models here.

class Post(models.Model):
    title = models.CharField(max_length=255)
    title_tag = models.CharField(max_length=255)
    author = models.ForeignKey(User, on_delete=models.CASCADE) #Delete Post when User is deleted
    body = models.TextField()

    def __str__(self):
        return self.title + ' | ' + str(self.author) #returns 'title | author' in admin page

    def get_absolute_url(self):
        return reverse("article_detail", args=(str(self.id)))

Error

File "/urls.py", line 3, in <module>
    from .views import AddPostView, ArticleDetailView, HomeView
  File "/views.py", line 5, in <module>
    from .forms import Post_form
  File "/forms.py", line 6, in <module>
    class Post_form(forms.ModelForm):
  File "/models.py", line 276, in __new__
    raise FieldError(message)
django.core.exceptions.FieldError: Unknown field(s) (model) specified for Post

I am new to django and still learning. Stuck here from quite long as the error message here is confusing. Any solutions? YouTube link which i am referring to - https://youtu.be/6-XXvUENY_8 Edit - models.py added

fields = ('title','title_tag', 'model', 'body')

you need to add the 'model' in field to your Model fields

soo

class Post(models.Model):
    title = 
    title_tag = 
    model = 
    body =

Your class Post(models.Model) doesn't have field with name model

From your model form

fields = ('title','title_tag', 'model', 'body')

Your Post model class should look like

class Post(models.Model):
    title = ...
    title_tag = ...
    model = ... # HERE
    body = ...

So either make sure the field exists or remove 'model' from fields tuple
