How to use all view and helper methods inside of Rails console for Rails 2.x and 3.x?

Question

helper.method_name worked in some version of Rails... are there ways that work in both Rails 2.2.2, 2.3.5, and 3.0.1? (to use all view and helper methods)

You can also try :

YourController.helpers.my_helper

for example :

> ApplicationController.helpers.content_tag(:div, "test")
=> "<div>test</div>"

This works with Rails 2, 3 and 4.1

This works. However there is an additional case wherein if you have defined your helper methods inside a file nested inside a module for e.g. `MyModule::ModuleSpecificViewHelper` (defined at `/app/helpers/my_module/module_specific_view_helper.rb`), then in rails console you should include that module first (if not already included) and then try `helper.your_method` and you should get it. – Jignesh Gohel Nov 22 '17 at 10:42
