Blog Website using Django

#blog #django #python

Hello Everyone,
This is MADHUBAN KHATRI, a self-taught programmer. In this post, I am creating a Blog Website using Pyton Framework - Django.
You need to create Django Project and an App. After this you have to install app in the settings.py INSTALLED APPS.

And follow these steps:-

models.py

In this file, u have to create 4 models

Contact
Post
Category
Comment

from django.db import models
from django.contrib.auth.models import User

# Create your models here.

class Contact(models.Model):
    name = models.CharField(max_length=100, default='None')
    email = models.EmailField(max_length=100, default='abc@gmail.com')
    sub = models.CharField(max_length=100, default='None')
    msg = models.TextField(default='None')

    def __str__(self):
        return self.name


class Post(models.Model):
    title = models.CharField(max_length=100)
    content = models.TextField()
    post_img = models.ImageField(upload_to='pictures')
    category_name =  models.CharField(max_length=50, default="None")


    def __str__(self):
        return self.title


class Category(models.Model):
    post_name = models.ManyToManyField(Post)
    cat_name = models.CharField(max_length=50)

    def __str__(self):
        return self.cat_name

class Comment(models.Model):
    post = models.ForeignKey(Post, on_delete=models.CASCADE)
    name = models.CharField(max_length=50)
    comment = models.TextField()

    def __str__(self):
        return self.comment

admin.py

from django.contrib import admin
from .models import Contact, Post, Category, Comment

# Register your models here.
admin.site.register(Contact)
admin.site.register(Post)
admin.site.register(Category)
admin.site.register(Comment)

app1-urls.py

This is app1-urls.py and here you have to create URL for your website.

from django.urls import path
from . import views

urlpatterns = [
    path('', views.home, name='home'),
    path('post/<int:post_id>', views.post, name='post'),
    path('create_account/', views.create_account, name='create_account'),
    path('contact/', views.contact, name='contact'),
    path('contact/save', views.save_contact, name='save_contact'),
    path('create_post/', views.create_post, name='create_post'),
    path('save_post/', views.save_post, name='save_post'),
    path('search/',  views.search_query, name='search'),
    path('<str:post_title>/create_comment',  views.add_comment, name='add_comment'),


]

views.py
