Create View - Function based Views Django - GeeksforGeeks

13 Jan, 2020
Create View refers to a view (logic) to create an instance of a table in the database. It is just like taking an input from a user and storing it in a specified table. Django provides extra-ordinary support for Create Views but let’s check how it is done manually through a function-based view. This article revolves around Create View which involves concepts such as Django Forms, Django Models.For Create View, we need a project with some models and forms which will be used to create instances of that model.
Illustration of How to create and use create view using an Example. Consider a project named geeksforgeeks having an app named geeks.
Refer to the following articles to check how to create a project and an app in Django.

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,
# import the standard Django Model# from built-in libraryfrom django.db import models   # declare a new model with a name "GeeksModel"class GeeksModel(models.Model):      # fields of the model    title = models.CharField(max_length = 200)    description = models.TextField()      # renames the instances of the model    # with their title name    def __str__(self):        return self.title
After creating this model, we need to run two commands in order to create Database for the same.
Python manage.py makemigrations
Python manage.py migrate

Now we will create a Django ModelForm for this model. Refer this article for more on modelform – Django ModelForm – Create form from Models. create a file forms.py in geeks folder,
from django import formsfrom .models import GeeksModel    # creating a formclass GeeksForm(forms.ModelForm):      # create meta class    class Meta:        # specify model to be used        model = GeeksModel          # specify fields to be used        fields = [            "title",            "description",        ]
Now we have everything ready for back end. Let’s create a view and template for the same. In geeks/views.py,
from django.shortcuts import render  # relative import of formsfrom .models import GeeksModelfrom .forms import GeeksForm    def create_view(request):    # dictionary for initial data with     # field names as keys    context ={}      # add the dictionary during initialization    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>
Let’s check what is there on http://localhost:8000/
Now let’s try to enter data in this form,
Bingo.! Create view is working and we can verify it using the instance created through the admin panel.This way one can create create view for a model in Django.
