View and Controllers association

in views file.

<%= render 'row', :object => @row_1 %>


<% row.each do |i| %>
  <%- if i.nil? -%>
    <%= render 'users/signup' %>
  <%- elsif i.respond_to?('category_id') -%>
    <%# render partial_for_post(i.category_id), :object => i %>
    <%= i.module %>
  <%- end -%>
<% end %>

if I write i.class it returns Post, so I thought module will be a
method in post_controller.rb. But it's not, can any one tell me, what is
it, and where can I get codes written for i.module.


If i is of the type Post, i.module will call the method module from the Post object in app/models/post.rb, not from a PostsController object as you seem to think it will.


Post (singular with capital) is the model

that's true, but here instead of Post.module, i.module is called.
and to know it's class when i put i.class it said Post, and in

no module function is there.. :frowning:

Post. module is not the same as i.module, i is an instance of the Post class that means you can do == and returns true.

acording to ruby docs this is what a module is

"A [Module]( is a collection of methods and
constants. The methods in a module may be
instance methods or module methods. Instance methods appear as methods in a
class when the module is included, module
methods do not. Conversely, module methods may be called without creating
an encapsulating object, while instance methods may not. (See [Module#module_function](

so what do you spect the module method to return from i.module?
