Creating forms in Django

 Creating forms in Django

In Django, we can use forms to handle user input and validate data. We can define forms in our app's forms.py file. Here's an example form for creating a new blog post:

python

Copy code

from django import forms

from .models import Post

class PostForm(forms.ModelForm):

    class Meta:

        model = Post

        fields = ['title', 'content']

In this example, we define a PostForm class that inherits from Django's ModelForm. We set the Meta class to use the Post model and define the fields attribute to include the title and content fields.

We can use our form in a view by importing it and rendering it in a template:

python

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()

            return redirect('post_list')

    else:

        form = PostForm()

    return render(request, 'create_post.html', {'form': form})

In this example, we define a create_post view that handles POST requests by creating a new Post object with the submitted form data. We render the create_post.html template with the PostForm object passed as context.
