Including captcha in a django form

Question

I'm trying to add Captcha to my Django form. I tried three different libraries but none of them worked for me and i don't know what i'm doing wrong. Here is my last try:

I used this library. My forms.py looks like this:

class NewUserForm(UserCreationForm):
    email = forms.EmailField(required=True)
    captcha = NoReCaptchaField()

    class Meta:
        model = User
        fields = ("username", "email", "password1", "password2")

    def save(self, commit=True):
        user = super(NewUserForm, self).save(commit=False)
        user.email = self.cleaned_data['email']
        if commit:
            user.save()
        return user

This is urls.py: path("login/", views.login_request, name="login").

This is the frontend: login.html: <script src="https://www.google.com/recaptcha/api.js" async defer></script>

I updated my settings.py file, so the error must not be there.

You can use django-simple-captcha.

1. Install it

pip install  django-simple-captcha

2. Add captcha to the INSTALLED_APPS in your settings.py
3. Run python manage.py migrate
4. Add an entry to your urls.py:

urlpatterns += [
       path(r'captcha/', include('captcha.urls')),
    ]

in forms.py:

from django import forms
from captcha.fields import CaptchaField
    
class YourForm(forms.Form):
    captcha = CaptchaField()

in template:

<form action="/your-name/" method="post">
   {% csrf_token %}
   {{ form.captcha }}
   <input type="submit" value="Submit">
</form>
