callΒΆ
Call an Erlang function.
The {% call %} tag is used to call the render/2 function of the module specified by the argument.
For example:
{% call mymodule %}
Will call mymodule:render(TemplateVariables, Context). Where TemplateVariables is the property list with all template variables and Context is the current Zotonic request context.
The render/2 function must return either {ok, IoList} or {error, Reason}.
It is possible to pass a single value instead of the complete list of all template variables:
{% call mymodule with value %}
This will call mymodule:render(Value, Context).
