Hello, It´s my first post here. :slight_smile: I´l following the guide of Ruby, but I need to know how the Ruby knows my path to other pages if I did not define anything, like this:

app/views/posts/index.html.erb:     <td><%= link_to 'Show', post %></td>     <td><%= link_to 'Edit', edit_post_path(post) %></td>

Other path(home/index.html.erb): <%= link_to "My first blog in Ruby on Rails", posts_path %>

I need help to know how Ruby knows the path of "post", "edit_post_path(post)" and "posts_path"?

Thank you all!

ps: The link that I´m following:

This is the convention over configuration thing. Once you define your map.resources in routes.rb, rails does the rest.

documentation for public instance method resources(*entities, &block) in ActionController::Resources in lib\action_controller\resources.rb has more information
