Create View - Function based Views Django
A Create View in Django allows adding new records to the database through a form.
- Shows a form for entering new data.
- Checks the submitted data for correctness.
- Saves the new record to the database if the form is valid.
- Provides a simple way to collect and store user input.
Example: Consider a project named 'geeksforgeeks' having an app named 'geeks'. After you have a project and an app, let's create a model of which we will be creating instances through our view.
In geeks/models.py:
from django.db import models
class GeeksModel(models.Model):
# fields of the model
title = models.CharField(max_length = 200)
description = models.TextField()
def __str__(self):
return self.title
After creating this model, we need to run two commands in order to create Database.
Python manage.py makemigrations
Python manage.py migrate
Create a forms.py file in the geeks folder and add the following code to create a ModelForm for this model, as ModelForm automatically generates form fields based on the model’s fields and is used to collect and validate user input.
from django import forms
from .models import GeeksModel
class GeeksForm(forms.ModelForm):
class Meta:
model = GeeksModel
fields = [
"title",
"description",
]
With the backend setup complete, create a view and template to handle the form in geeks/views.py:
from django.shortcuts import render
from .models import GeeksModel
from .forms import GeeksForm
def create_view(request):
context = {}
form = GeeksForm(request.POST or None)
if form.is_valid():
form.save()
context['form'] = form
return render(request, "create_view.html", context)
Create a template in templates/create_view.html:
<form method="POST" enctype="multipart/form-data">
<!-- Security token -->
{% csrf_token %}
<!-- Using the formset -->
{{ form.as_p }}
<input type="submit" value="Submit">
</form>
Visit development server: http://localhost:8000/
Let's try to enter data in this form:
Create view is working and we can verify it using the instance created through the admin panel.
This approach demonstrates how to create a Create View for a model in Django.
In a function-based Create View, what is the required sequence when handling a POST request to create a new record?
-
A
Validate submitted form data → save new object → redirect or render response
-
B
Save data → validate form → render template
-
C
Show empty form → redirect to login → save data
-
D
Delete old records → save new object → return blank form
On POST, submitted data must be validated; if valid, new object is saved, then response (often redirect) is returned.
Which file usually contains the view function definition for a Create View in a Django app?
-
A
urls.py
-
B
views.py
-
C
settings.py
-
D
models.py
Django app’s views (including Create Views) are normally defined in the views.py file.
