This simple article demonstrates of django form checkbox validation example. I would like to show you django form checkbox. if you have question about django form validation before submit then I will give simple example with solution. I explained simply step by step django form validation example. You just need to some step to done how to use checkbox form validation in django.
A checkbox is a button with two states: checked and unchecked. The default widget for checkbox input is CheckboxInput. A boolean field in a Django form is a checkbox field that only accepts True or False values. The empty value is False by default.
Let's see bellow example I explained simply about django form checkbox validation example.
Step 1: Create a Project
In this step, we’ll create a new django project using the django-admin. Head back to your command-line interface and run the following command:
django-admin startproject exampleapp
Step 2: Create a App
Now we'll create a single app called polls to store a list of post names. We're keeping things intentionally basic. Stop the local server with Control+c and use the startapp command to create this new app.
python3 manage.py startapp core
Step 3: Update setting.py
Next, In this step we require to do two things in our settings.py file, One is our installed app name Add the below lines to your settings.py file:
INSTALLED_APPS = [
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'core',
]
Step 4: Create a Form
First of all in this step we will create a new file called forms.py and create a Django form you need to use Django Form Class
core/forms.py
from django import forms
class EmpDetailsForm(forms.Form):
agree = forms.BooleanField(
label='Agree',
required = True,
disabled = False,
widget=forms.widgets.CheckboxInput(
attrs={'class': 'checkbox-inline'}),
help_text = "I accept the terms in the License Agreement",
error_messages ={'required':'Please check the box'}
)
Step 5: Creating the Views
In this step, we need to create the views for performing the post request data is to cleaned to cleaned_data method.Open the core/views.py file and add:
core/views.py
from django.shortcuts import render
from .forms import EmpDetailsForm
def emp_form(request):
error = {}
form = EmpDetailsForm(request.POST)
error['form'] = form
if request.POST:
if form.is_valid():
try:
return redirect('/')
except:
pass
return render(request,'form.html',error)
Step 6: Creating the Templates
Next, open the core/templates/form.html file and the add:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Tuts-Station.com</title>
<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/[email protected]/dist/css/bootstrap.min.css">
<style type="text/css">
body{
background-color: #f7fcff;
}
</style>
</head>
<body>
<div class="container mt-5 pt-5">
<div class="row d-flex justify-content-center">
<div class="col-md-9">
<div class="card">
<div class="card-header">
<h3>Django Form Checkbox Validation Example - <span class="text-primary">Tuts-Station.com</span></h3>
</div>
<div class="card-body">
<form method = "post" enctype="multipart/form-data">
{% csrf_token %}
{{ form.as_p }}
<button type="submit" class="btn btn-success">Submit</button>
</form>
</div>
</div>
</div>
</div>
</div>
</body>
</html>
Step 7: Creating Urls
In this section, we’ll create the urls to access our views.Go to the urls.py core/urls.py file and update it as follows:
core/urls.py
from django.urls import path, include
from . import views
urlpatterns = [
path('form', views.emp_form),
]
Next, we will require the modify the urls.py your root preoject folder lets update the file.
exampleapp/urls.py
from django.contrib import admin
from django.urls import path, include
urlpatterns = [
path('admin/', admin.site.urls),
path('', include('core.urls')),
]
Run the Server
In this step, we’ll run the local development server for playing with our app without deploying it to the web.
python manage.py runserver
Next, go to the url address bar with a web browser.
http://localhost:8000/form
I Hope It will help you....
