Django message template tag checking

Question

I want to check whether the message tag are INFO ?

How to check that in the template file?

I tried this but it didn't work:

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

I even tried other combinations like message.tag.info == "INFO" etc but they didn't seem to work. What is the correct way of checking it?

Answer 1

Using bootstrap

{% block messages %}
    {% if messages %}
        {% for message in messages %}
            <div class="alert alert-{{ message.tags }}">  <!-- singular -->
                <a class="close" data-dismiss="alert">×</a>
                {{ message|safe }}
            </div>
        {% endfor %}
    {% endif %}
{% endblock %}

So it's {{ message.tags }} you're looking for

I understand this. But how to check if a particular tag is INFO or SUCCESS ? – Truncation

{% if message.tags == 'info' %} if it only holds a single one, else you could iterate it – Hhour

@Andrei leveraging tags styling within django templates, its an encore. By the way, this question dates back from 2013, no idea if this is all still valid. – Hhour

Here you can check in html using which type of tag it is use single quote not double it will give an error.

{% if message.tags == 'error' %}

Here is a simple way I implemented this.

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

Totally Worked for me....
