How to make a Country field in Django?
If you need to add a location field in your form or database, you can do that using charfield but it is still not that good idea. In Django, we have a third-party package called 'django-countries' that provides the country field. In this article, let's see how to use django-countries to add a Country field in Django.
First, create a Django project and an app.
Add the app in INSTALLED_APPS and set up urls.
Install the django-countries module −
pip install django-countries
In settings.py, add this −
INSTALLED_APPS += [ 'django_countries']
Example
In app's urls.py −
from django.urls import path
from . import views
urlpatterns = [
path('', views.home, name="home"),
]
First setup your urls.
In views.py −
from django.shortcuts import render
from django import forms
from .models import Data
class SalaryForm(forms.ModelForm):
class Meta:
model=Data
fields="__all__"
def home(request):
if request.method=='POST':
form=SalaryForm(request.POST)
if form.is_valid():
form.save()
else:
form=SalaryForm()
return render(request,'home.html',{'form':form})
Here we simply created a form and rendered it in GET request handler of our view. In POST handler, we save the form data.
Create a templates folder in app directory and a home.html in it. In home.html −
<!DOCTYPE html>
<html>
<head>
<title>
TUT
</title>
<style>
</style>
</head>
<body>
<h2>FORM</h2>
<form action="/" method="post">
{% csrf_token %}
{{ form }}
<input type="submit" value="Submit">
</form>
</body>
</html>
This is the front-end html of our form.
In models.py −
from django.db import models from django_countries.fields import CountryField # Create your models here. class Data(models.Model): Name=models.CharField(max_length=100) salary = models.CharField(max_length=20) country_of_work = CountryField(blank=True)
Here we created a model in which we simply added a country field which will store the country data.
Now, make migrations and migrate. You are all done. Now, you can proceed to check the output.
