Prune's Captcha

What is it for?

Captcha helps prevent robots from spamming using your forms.

Prerequisites

• To be installed on a Prune Django project that uses poetry or UV

UV project

Installation

Run the following command in the console:

uv add captcha_prune

Updating the captcha

Don't hesitate to regularly run uv sync --upgrade, as the captcha evolves with time and our practices!

Poetry project

Installation

Run the following command:

poetry add prune_captcha

Updating the captcha

Don't hesitate to regularly run poetry update, as the captcha evolves with time and our practices!

Captcha Integration

Configuration

In settings.py, set the path to the images used for the puzzle:

PUZZLE_IMAGE_STATIC_PATH = "website/images/"

Utilisation

• GET request (form display)

  • Use create_and_get_puzzle to generate the captcha data.

  • Passes the data into the context under the puzzle variable.

  • Include the component in your template:

    from captcha_prune.utils import create_and_get_puzzle
    

    {% include "captcha_prune/components/captcha.html" %}
    

• POST request (form submission)

  -   Use verify_captcha to validate the captcha.
  
      ```python
      from captcha_prune.utils import verify_captcha
      ```
  
      ```python
      verify_captcha(request, redirect("/"), redirect("website:contact-page"), form)
      ```
  
  -   No feedback if the captcha is correct.
  
  -   Redirects in case of expired session or incorrect captcha.
  

Example

```python
from django.shortcuts import render, redirect

from django.contrib import messages
from captcha_prune.utils import create_and_get_puzzle, verify_captcha
from .forms import ContactForm

def contact_view(request):
    if request.method == "POST":
        form = ContactForm(request.POST)
        if form.is_valid():
            verify_captcha(
                request,
                redirect("/"),
                redirect("website:contact-page"),
                form
            )
            messages.success(request, "Formulaire soumis avec succès.")
            return redirect("/")
        else:
            puzzle = create_and_get_puzzle(request)

        form = ContactForm()
        puzzle = create_and_get_puzzle(request)
return render(
    request,
    "website/pages/contact/page.html",
    {"form": form, "puzzle": puzzle},
)
