如何在Ruby on Rails中链接到users / id / microposts？

Question

I need create a link to users/id/microposts where id is the user id. I was wondering how I could do that with link_to ?

The HTML code is I am using for the moment is :

<strong><a href="/users/<%= @user.id %>/microposts">Microposts</a></strong> <%= user.microposts.count %>

Which renders the following :

<a href="/users/1/microposts">Microposts</a>

Answer 1

Assuming that you have your routes setup correctly, that would be a nested route for the microposts, In rails 3 it would be

resources :users do
  resources :microposts
end

Then in your view, with link_to you can

<%= link_to "Microposts", user_microposts_path(user) %>

This might be current_user, @user ... whatever user object you want the microposts, it might be from

@users.each do |user|
  <%= link_to "Microposts", user_microposts_path(user) %>
end

OR

<%= link_to "Microposts", user_microposts_path(current_user) %>

EDIT: Added in the user object I forgot to passin and some examples with it.

In routes.rb, you should have something like this:

match '/users/:id/microposts' => 'microposts#index_by_user', :as => :microposts_by_user

and in view, you can do like this:

<%= link_to "Microposts", microposts_by_user_path( @user) %>
