How Can You Output Something When Login Is Completed? Django

I'm trying to build a form that when the login button is clicked, it displays a login succesful message. Here is the thing, I want that when the 'login' button is clicked, the user

Solution 1:

Django Messages framework is a great simple way to show a one-time message to the user.

In a FormView, a message might look like this:

from django.contrib import messages

classMyFormView(FormView):

    defget_success_url(self):
        messages.success(self.request, 'Thank you. We will contact you as soon as we can.')
        return reverse('contact')

You can render a message in the template like this:

{% if messages %}
        {% for message in messages %}
            <p>
                    {{ message }}
            </p>
        {% endfor %}
{% endif %}

You could make a partial for messages, which I do sometimes. You can also use different message levels other than success.

Read more about them here: https://docs.djangoproject.com/en/3.1/ref/contrib/messages/

Solution 2:

One way to approach this could be to use the success message.

from django.contrib import messages

defmy_view(request):
   ...
   if form.is_valid():
      ....
      messages.success(request, 'Success message.')

Solution 3:

To show one-time messages you can use Django's messages framework. Here is a custom login view that adds a "You are logged in" message:

from django.contrib.auth.views import LoginView
from django.contrib import messages

defMyCustomLoginView(LoginView):
    defform_valid(self, form):
        messages.add_message(self.request, messages.SUCCESS, 'You are logged in.')
        returnsuper().form_valid(form)

And here is a template that will display this message:

{% if messages %}
<ul class="messages">
    {% for message in messages %}
    <li{% if message.tags %} class="{{ message.tags }}"{% endif %}>{{ message }}</li>
    {% endfor %}
</ul>
{% endif %}
