What is a Model Form?

Model forms are used to automatically create forms from Django models. This saves time by automatically generating fields that correspond to the model’s attributes.

Creating a Model Form

1. Define the Model:

from django.db import models

class Post(models.Model):
    title = models.CharField(max_length=100)
    content = models.TextField()
    created_at = models.DateTimeField(auto_now_add=True)

2. Create the Model Form: In forms.py, create a form based on the model:

from django import forms
from .models import Post

class PostForm(forms.ModelForm):
    class Meta:
        model = Post
        fields = ['title', 'content']

3. Rendering the Model Form: In the view:

from django.shortcuts import render
from .forms import PostForm

def create_post(request):
    if request.method == 'POST':
        form = PostForm(request.POST)
        if form.is_valid():
            form.save()  # Save the data to the database
            return redirect('success')
    else:
        form = PostForm()
    return render(request, 'create_post.html', {'form': form})
