When to use helper methods and private methods in Rails? -

-

i have been hearing controller should concise possible. so, try keep of processing work in helper corresponding controller. but, little confused regarding whether should instead use private controller methods or helper methods.

i using helper methods processing , returning values. have no other usage now. not called views.

that's bad idea in general. helper methods shouldn't used except specific convert-something-into-string stuff (basically, should used only in views).

for else, should use service objects or similar, basically, poro (plain old ruby objects)

in controllers want handle authentication , render right thing, don't want deal else otherwise become complex.

you might want check these books improve knowledge topic:

  • growing rails applications book on how avoid putting code in wrong places , how keep codebase maintenable on long term
  • poodr ruby guide on how write object-oriented code, it's must any developer , understand why using helper it's bad idea

i realize question might seem trivial some, it's these types of things find myself fighting quite bit , want make sense of despite seeming losing battle in .net (for me anyway). so, if following: using system.web; ... applicationuser user = system.web.httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); that produces error in title , red getowincontext() , error cannot resolve symbol 'getowincontext()' however, if following (remove system.web in front of httpcontext ), works expected (or @ least no errors): using system.web; ... applicationuser user = httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); however, if (same line that's working using system.web commented out): //using system.web; ... applicationuser user = httpcontext.getowincontext().getusermana...
