rails 4 engine optional shared helper -

-

i upgraded engine rails 4 , i'm having problems trying configure optional shared helper. helper assessable::displayhelper has 2 methods render html.

what mean optional is

  • the default config desired helper should made available main.app use outside engine, details hidden. (the html generated hash generated engine used main app)
  • an optional generator installs helper in helpers/assessable/display_helper app user can modify if wish.

the optional generator works fine, over-riding helper in engine, can't figure out way make default mode work.

i've read note helper load order in rails 4 release notes, not sure need change. i've tried

  • adding helper assessable::displayhelper application controller (not preferred)
  • trying include assessable::displayhelper in stubbed helper.
  • a few other stabs in dark

produces , error:

runtimeerror: circular dependency detected while autoloading constant assessable::displayhelper ... /users/me/.rvm/gems/ruby-2.0.0-p247@rails4/gems/actionpack-4.0.0/lib/action_controller/railties/helpers.rb:17:in `inherited' /users/me/work/pm/app/controllers/application_controller.rb:1:in `<top (required)>'

i gone , forth between having display functions in class , in helper. switched helper because had trouble getting class installed in main app. goal have `{class.}display_xxx(hash,post) work either default or optional config.

any suggestions on either approach helpful.

i gave up. know 1 looking @ rails4, @ least yet.

i ended using 1 old suggestion , generating included helper in applications helper directory - versus name-spaced directory. not want wanted do, maybe sometime later i'll figure out. install:helper method replaces helper include full code.

this question has answer here: why write “.call(this)” @ end of javascript anonymous function? [duplicate] 4 answers what kind of design pattern , significance of using closure? (function(){ // code here }).call(this); edit then difference between above code , following this keyword still refer same object in both ways.
