NAME

Dotiac::DTL::Tag::ifchanged - The {% ifchanged [VARIABLE] %} tag

SYNOPSIS

Template file:

        {% for x in loop %}
                {% ifchanged %}
                        Posted on {{ x.date }}
                {% endifchanged %}
                {% ifchanged x.poster %}
                        Reply by {{ x.poster }} on {{ x.date }}
                {% endifchanged %}
        {% endfor %}

DESCRIPTION

Without VARIABLE, ifchanged only renders its content, if the content changed since the last iteration of a loop above.

With VARIABLE, ifchanged only renders its content, if VARIABLE has changed since the last iteration of a loop above.

Note

Every ifchanged stands on its own, even if they have the same variable or content to check.

        {% ifchanged x.post %}
                ... {# This will be displayed #}
        {% endifchanged %}
        {% ifchanged x.post %}
                ... {# This will also be displayed #}
        {% endifchanged %}

BUGS AND DIFFERENCES TO DJANGO

This implementation also supports the {% else %} tag in ifchanged, which is not included in Django, but there is a patch for that.

        {% for timepoint in timepoints %}
                {% ifchanged timepoint.day %}
                        It's a new day.
                {% else %}
                        It's still {{ timepoint.day }}
                {% endifchanged %}
        {% endfor %}
