Template Tags¶
CWF contains two custom templatetags that it uses when it’s constructing the template for the menu generation functionality provided.
These are:
varset¶
Usage for this tag is:
{% load varset %}
{% varset name_of_new_variable %}
{% if some_condition %}
{{some_value}} blah
{% else %}
another value
{% endif %}
{% endvarset %}
After we load
the varset templatetags, we have available to us a tag called
varset
. It takes the name of the variable to create
and will put the contents between the start of that tag till endvarset
and
make that the value of the new variable, which can be used in your template any
point after this.
So in the example above, your template will now have a variable available called
name_of_new_variable
with whatever that block of code evaluates into.
wrapped¶
Usage for this tag is:
{% load wrapped %}
{% wrapped li 'class="awesome" style="background-color:red"' %}
{% if condition %}
<p>wicked awesome</p>
{% endif %}
{% endwrapped %}
This allows us to create an html element that will only appear if it has something inside of it.
So in the example above it will create:
<li class="awesome" style="background-color:red">
<p>wicked awesome</p>
</li>
If condition
is truthy. Otherwise, there isn’t anything between the
wrapped
and endwrapped
tags except for whitespace and so it won’t even
output the <li>
.
