Here's what I have: - 2 controllers which are 80% similar. I already have a factory which both use to get the data which will be displayed. - I use the controllerAs notation, with var vm = this - there's a mix of vars and functions which will be used in the view and therefore are created inside vm, and some other

Displaying a Random Database Item to View — Rails

由 不羁的心 提交于 2019-12-12 01:56:07

That is, the final part of the controller name will always resolve to a file called name_controller.rb, and any leading path information will be used to navigate through subdirectories, starting in the app/controllers directory. Imagine that our program has two such groups of
