EVILEG-CORE. Using Google reCAPTCHA

This will be the first article on the use of a set of established utilities that are present in the core of the EVILEG site. This part of the site’s program code is in open source, so I want to talk about what functionality is present in this battery and how to use it.

I'll start by using Google reCAPTCHA , and what is required to quickly implement this functionality.

Register reCAPTCHA

The first step is to register the site in the admin reCAPTCHA .

An example of registering a site on Google reCAPTCHA

Implementation

Adding Google reCAPTCHA will consist of two steps:

  1. Implementing reCAPTCHA on the client side, i.e. in HTML code
  2. Внедрение reCAPTCHA на серверной стороне

When registering a site, two keys will be generated:

  1. Site key - The key to be placed on the HTML page
  2. Secret key - The key that will be used to communicate the site and the Google service reCAPTCHA

The implementation process will be as follows. On the HTML page in a form that requires validation of user actions, place the reCAPTCHA script and the site key.

On the server side, we add a decorator to the request method for Class Based View.

Install EVILEG-CORE

pip install evileg-core

Also evileg_core will pull up all the dependencies necessary for this package. Including the requests library, which is used to execute the captcha verification request.

settings.py

Add evileg_core to installed applications

INSTALLED_APPS = [
    ...
    'evileg_core',
]

We also add reCAPTCHA Secret Key and Site Key.

GOOGLE_RECAPTCHA_SECRET_KEY = 'XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX'
GOOGLE_RECAPTCHA_SITE_KEY = 'XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX'

urls.py

We wrap the necessary view with the decorator

# -*- coding: utf-8 -*-

from django.conf.urls import url
from evileg_core.decorators import recaptcha

from . import views

app_name = 'registration'
urlpatterns = [
    path('register/', recaptcha(views.RegisterView.as_view()), name='register'),
]

views.py

And in the view itself, we check the validity of reCAPTCHA. In my case, this was a view inherited from the FormView class.

class RegisterView(FormView):
    form_class = UserCreationForm
    template_name = 'register.html'

    def form_valid(self, form):
        # reCAPTCHA validation check
        if self.request.recaptcha_is_valid:
            form.save()
            return render(self.request, 'register_success.html', self.get_context_data())
        return render(self.request, 'register.html', self.get_context_data())

Client side

On the client side, you need to add the script connection code, the location of the captcha, as well as the output of error messages.

{% extends 'home/base.html' %}
{% block content %}
  <form action="{% url 'registration:register' %}" method="post">
    {% csrf_token %}
    {{ form.as_p }}
    {% load recaptcha from evileg_core %}
    {% recaptcha 'form-group' %}
    {% if messages %}
      {% for message in messages %}
        {{ message }}
      {% endfor %}
    {% endif %}
    <input type="submit" value="Register">
  </form>
{% endblock %}

Result

As a result, we get a fairly simple implementation of reCAPTCHA on the Django site.
