how to add category to blog project django - django

Question

i developed a blog project by watching many open-source courses and create my own django custom admin dashboard where i want to add a category option to my blog project, i have watched some tutorial on as well but couldn't find them helpful
models.py
from django.db import models
from django.forms import ModelForm
from farmingwave.models import BaseHeader,Submenu
class Category(models.Model):
mainmenu=models.ForeignKey(BaseHeader,null=True,on_delete=models.SET_NULL)
submenu=models.ForeignKey(Submenu,on_delete=models.CASCADE)
class AdSideMenu(models.Model):
title_id = models.AutoField(primary_key=True)
title_name = models.TextField()
url = models.TextField()
priority = models.IntegerField()
submenu_status = models.TextField()
class Meta:
db_table = 'admin_side'
class CreateBlog(models.Model):
id = models.AutoField(primary_key=True)
blog_Title = models.TextField(max_length=100)
content = models.TextField(max_length=5000)
category = models.ForeignKey(Category,null=True,on_delete=models.SET_NULL)
class Meta:
db_table = 'create_blog'
they are inhereting data from another app
models.py
`class BaseHeader(models.Model):
main_id = models.AutoField(primary_key=True)
title_name = models.TextField()
url = models.TextField()
priority = models.IntegerField()
submenu_status = models.TextField("false")
class Meta:
db_table = 'base_header'
class Submenu(models.Model):
sub_id = models.AutoField(primary_key=True)
main_id = models.IntegerField()
sub_name = models.TextField()
url = models.TextField()
priority = models.IntegerField()
mainmenu=models.ForeignKey(BaseHeader,on_delete=models.CASCADE)
class meta:
db_table = 'base_subheader'`
and the view function:
def create_blog(request):
if request.method =='POST':
form = CreateBlogForm(request.POST)
if form.is_valid():
form.save()
form = CreateBlogForm()
else:
form = CreateBlogForm()
base = BaseHeader.objects.all()
sub = Submenu.objects.all()
create = CreateBlog.objects.all()
category = Category.objects.all()
context = {
'form' : form,
'createblog' : create,
'category' : category,
'menu' : base,
'sub_menu' : sub,

Answer 1

Why not make the category a select item?
CATEGORY_CHOICES = (
('sports', 'sports'),
('tech', 'tech'),
('politics', 'politics')
)
category = models.CharField(max_length=100, choices=CATEGORY_CHOICES, blank=False)
You'd be able to access it like any other field now, so let's say the user clicked on "Politics articles" you can add a .filter(category="politics") and access it in the templates through {{ article.category }}
I don't know why there are all of these lines in your code, nor do I know the scale of your project, but that's how I would go about doing it.
