SOLVED: How to add existing helper in an extended controller (Redmine Plugin Dev)

Added by Dan A. S. almost 6 years ago

Can anyone guide me through the right way to add an existing Helper into an extended controller which previously did not contain this helper.

For example, I have extended the timelog_controller.rb controller in timelog_controller_patch.rb. Then, I tried to add the helper Queries, which brings some functionality that I want to use in my patch.

If I add the helper in my patch (my timelog extended control), I always get the same error:

Error: uninitialized constant Rails:: Plugin:: TimelogControllerPatch (NameError)

Here is an example of how I have done:

module TimelogControllerPatch       
    def self.included(base)
        base.send(:include, InstanceMethods)
        base.class_eval do
          alias_method_chain :index, :filters
        end
    end
    module InstanceMethods
        # Here, I include helper like this (I've noticed how the other controllers do it)
        helper :queries
        include QueriesHelper

        def index_with_filters
            # ...
            # do stuff
            # ...
        end
    end # module
end # module patch

However, when I include the same helper in the original controller, everything works fine (of course, this is not the right way).

Could someone tell me what am I doing wrong?

Thanks in advance :)
