Django MESSAGE_TAGS

Django MESSAGE_TAGS is a dictionary that stores message level tags and their associated CSS classes. It is used by the messaging framework in Django to display success, warning, and error messages to users.

Usage

The MESSAGE_TAGS dictionary can be found in the settings.py file of your Django project. It looks like this:

MESSAGE_TAGS = {
    messages.DEBUG: 'debug',
    messages.INFO: 'info',
    messages.SUCCESS: 'success',
    messages.WARNING: 'warning',
    messages.ERROR: 'error',
}

Each message level tag is associated with a CSS class. These CSS classes can be used to style the different types of messages to match the design of your website.

In your views, you can use the messaging framework to add messages to the messages framework like this:

from django.contrib import messages

def my_view(request):
    messages.success(request, 'Your message was sent successfully.')
    return redirect('home')

When the user is redirected to the home page, the message will be displayed to the user using the appropriate CSS class based on the message level tag.

Examples

Here are some examples of how the different message level tags can be used:

messages.debug(request, 'This is a debug message.')
messages.info(request, 'This is an informational message.')
messages.success(request, 'This is a success message.')
messages.warning(request, 'This is a warning message.')
messages.error(request, 'This is an error message.')

In your CSS file, you can style the different types of messages like this:

.message.debug {
    background-color: #ddd;
    color: #333;
}

.message.info {
    background-color: #369;
    color: #fff;
}

.message.success {
    background-color: #0c0;
    color: #fff;
}

.message.warning {
    background-color: #ff0;
    color: #000;
}

.message.error {
    background-color: #f00;
    color: #fff;
}

Note: The default message tags and their associated CSS classes can be overridden in your settings.py file.
