Django — Messages

Message Framework

from django.contrib import messages

def my_view(request):
    messages.success(request, 'Operation completed successfully!')
    messages.error(request, 'Something went wrong.')
    messages.warning(request, 'Please be careful.')
    messages.info(request, 'Here is some information.')
    return redirect('home')

Message Tags

Tag	Description
success	Successful operation
error	Error occurred
warning	Warning message
info	Information
debug	Debug message

Template Display

{% if messages %}
    {% for message in messages %}
        <div class="alert alert-{{ message.tags }}">
            {{ message }}
        </div>
    {% endfor %}
{% endif %}

Message Levels

from django.contrib.messages import constants as message_constants

# Optional: customize message levels
message_constants.DEBUG = 10
message_constants.INFO = 20
message_constants.SUCCESS = 25
message_constants.WARNING = 30
message_constants.ERROR = 40

Extra Tags

messages.success(request, 'Profile updated', extra_tags='profile')

Mini Practice

1. Add success and error messages
2. Display messages in templates
3. Use different message levels
