19/32The forms functionality in Django allows developers to create, validate and manage forms in an efficient and organized way. Below, we will explore how to create forms in Django step by step.
How do I create forms in Django?
To create a new form in Django, you must first create a class that inherits from forms.Form. This class will contain all the fields we want to include in the form.
- Create the file forms.py:
from django import formsclass ProductForm(forms.Form):name = forms.CharField(max_length=200, label='Name') description = forms.CharField(max_length=300, label='Description') price = forms.DecimalField(max_digits=10, decimal_places=2, label='Price') available = forms.BooleanField(initial=True, label='Available', required=False) photo = forms.ImageField(label='Photo', required=False)
How is the form data handled in Django?
Once the form is created, we need to define how to handle the data when the user submits the form. This includes validating the data and saving it to the database.
- Save method to save data:
def save(self): from.models import Product data = self.cleaned_data Product.objects.create( name=data['name'], description=data['description'], price=data['price'], available=data['available'], photo=data['photo'] )
How to create the view for the form?
The view connects the form with the template and handles the user request. We will use a generic Django view to simplify this process.
- Create the view:
from django.views.generic.edit import FormViewfrom django.urls import reverse_lazyfrom.forms import ProductFormclass ProductFormView(FormView):template_name = 'products/add_product.html'form_class = ProductForm success_url = reverse_lazy('product_list') def form_valid(self, form):form.save() return super().form_valid(form)
How to configure the URLs for the view?
You need to configure the URLs for the view to be accessible from the browser.
- Configure urls.py:
from django.urls import pathfrom.views import ProductFormView urlpatterns = [ path('add/', ProductFormView.as_view(), name='add_product') ]
How is the template for the form created?
The template defines the HTML structure of the form and how it is rendered on the web page.
- Create the add_product.html template
:<h1>AddProduct</h1><form method="post" enctype="multipart/form-data">{% csrf_token %} {{ form.as_p }} <button type="submit">Add</button></form>.
What is the CSRF token and why is it important?
The CSRF token is a security measure that protects against Cross-Site Request Forgery attacks. Django automatically includes it in forms to ensure that requests come from trusted sources.
How is redirection handled after form submission?
Redirection after form submission is handled by setting the success_url parameter in the view, using reverse_lazy to get the destination URL.
How is the product validated and saved?
When the form is valid, the form_valid method is in charge of calling the save method of the form to save the product in the database.

` elements), where each form field is wrapped in its own paragraph. This is a convenient way to quickly generate an HTML form without having to manually write the HTML for each field. Here's a breakdown of how it works: ### Usage When you use `{{ form.as_p }}` in a Django template, Django automatically generates the HTML for the form, including the form fields and their labels, wrapped in `
` tags. This is particularly useful for simple forms where you want a quick and easy way to render the form fields.
