Cache.warmup ViewHelper <f:cache.warmup>

ViewHelper to insert variables which only apply during cache warmup and only apply if no other variables are specified for the warmup process.

If a chunk of template code is impossible to compile without additional variables, for example when rendering sections or partials using dynamic names, you can use this ViewHelper around that chunk and specify a set of variables which will be assigned only while compiling the template and only when this is done as part of cache warmup. The template chunk can then be compiled using those default variables.

This does not imply that only those variable values will be used by the compiled template. It only means that DEFAULT values of vital variables will be present during compiling.

If you find yourself completely unable to properly warm up a specific template file even with use of this ViewHelper, then you can consider using f:cache.disable ViewHelper to prevent the template compiler from even attempting to compile it.

USE WITH CARE! SOME EDGE CASES OF FOR EXAMPLE VIEWHELPERS WHICH REQUIRE SPECIAL VARIABLE TYPES MAY NOT BE SUPPORTED HERE DUE TO THE RUDIMENTARY NATURE OF VARIABLES YOU DEFINE.

<f:cache.warmup variables="{foo: bar}">
   Template code depending on {foo} variable which is not
   assigned when warming up Fluid's caches. {foo} is only
   assigned if the variable does not already exist and the
   assignment only happens if Fluid is in warmup mode.
</f:cache.warmup>
