Django - Message

此筆記將紀錄如何使用Django Message 功能

參考資料：https://docs.djangoproject.com/en/1.11/ref/contrib/messages/

設定預設Tag

# settigns.py

from django.contrib.messages import constants as messages

MESSAGE_TAGS = {

messages.INFO: '',

50: 'critical',

}

# views.py

from django.contrib import messages

messages.add_message(request, messages.INFO, 'Hello world.')

# template

            {% if messages %}

                {% for message in messages %}

                <p {% if message.tags %} class="bg-{{ message.tags }}"{% endif %}>{{ message }}</p>

                {% endfor %}

            {% endif %}

各種TAG

messages.debug(request, '%s SQL statements were executed.' % count)
messages.info(request, 'Three credits remain in your account.')
messages.success(request, 'Profile details updated.')
messages.warning(request, 'Your account expires in three days.')
messages.error(request, 'Document deleted.')

客制level

剛剛設定預設Tag的 50 = critical

def my_view(request):
    messages.add_message(request, 50, 'A serious error occurred.')
