marionette - Cannot get subview to be inserted into layout -


i creating webapp using marionette.backbone , got module creates layout , add 3 subviews it.

the layout rendered fine regions not filled each sub view. missing. no error in console.

this controller:

@appic.module "projectsapp.add", (add, app, backbone, marionette, $, _) ->      add.controller =          addproject: ->             @layout = @getlayoutview()              @layout.on "show", =>                 @showleft                 @showcontent                 @showright              app.mainregion.show @layout          showleft: ->             leftview = @getleftview             @layout.leftregion.show leftview          showcontent: ->             contentview = @getcontentview             @layout.contentregion.show contentview          showright: ->             rightview = @getrightview             @layout.rightregion.show rightview          getleftview: ->             new add.left          getcontentview: ->             new add.form          getrightview: ->             new add.right          getlayoutview: ->             new add.layout

this view part of module

@appic.module "projectsapp.add", (add, app, backbone, marionette, $, _) ->      class add.layout extends app.views.layout         template: "projects/add/templates/add_layout"          regions:             leftregion: "#left-region"             contentregion: "#content-region"             rightregion: "#right-region"      class add.left extends app.views.itemview         template: "projects/add/templates/_left"      class add.right extends app.views.itemview         template: "projects/add/templates/_right"      class add.form extends app.views.itemview         template: "projects/add/templates/_form"

you assigning pointer function rather functions result in show methods. try:

    showleft: ->         leftview = @getleftview()         @layout.leftregion.show leftview      showcontent: ->         contentview = @getcontentview()         @layout.contentregion.show contentview      showright: ->         rightview = @getrightview()         @layout.rightregion.show rightview

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
