Counter

The “counter” template tag library provides 2 template tags:

  • counter: increments a counter on each call

counter

The {% counter %} template tag is useful when you want to use a custom counter. It can be used outside a specific loop, or used over multiple loops...

The {% counter %} template tag accepts several optional parameters:

  • name. A string. It identifies the counter. Default value is ‘default’.
  • start. An integer. The value of the counter at the very first call. Default value is 0.
  • step. An integer. The increment or decrement amount. Default value is 1.
  • ascending. A boolean. Whether the counter is incremented (True) or decremented (False). Default value is True.
  • silent. Whether to render (False) or not (True) the current counter value. Default value is False.
  • assign. A string. If not empty, the current value of the counter is assigned to the context variable with the corresponding name. Default value is “” (do not assign).

Notice that the start, ascending and step values are only parsed on counter initialization.

The list of available counters is stored in the context, under the variable name settings.TEMPLATEADDONS_COUNTERS_VARIABLE, which is “_templateaddons_counters” by default.
