Ruby on Rails链接_至

Question

I am using link_to with some HTML elements and this is what I have : <% link_to "", { :controller => "posts" }, :id => "posts", :class => "read-more" %>

But I want it that it will link to the posts with the id that each post has, any help would be most appreciated.

Thank You

Answer 1

config/routes.rb

resources :posts

---

<% @posts.each do |post| %>
  <%= link_to "View post", post_path(post), :id => "posts", :class => "read-more" %>
<% end %>

Answer 2

Your hash is missing a few params...

<% link_to "", { :controller => "posts", :action => "show", :id => post.id}, :id => "posts", :class => "read-more" %>

But I recommend

<% link_to "", post_path(post), :id => "posts", :class => "read-more" %>

I think what you are asking is this. You have an array or active record relation @posts which you want to show in a webpage with links to each post. If I'm right you can do

<% @posts.each do |post| %>
    <%= link_to "", { :controller => "posts" }, :id => post.id, :class => "read-more" %>br>
<% end %>

But you have to specify the action which will be triggered when the link is clicked.

I think this should work

<% @posts.each do |post| %>
    <%= link_to "", { :controller => "posts" , :action => :show}, :id => post.id, :class => "read-more" %>br>
<% end %>

How about this?

<% @posts.each do |post| %>
  <%= link_to "POST", post_path(post), :id => post.id %>
<% end %>
