Query string passing in Ruby on Rails -

-

i want pass id=1 when press link.

**link** **view/index.html.erb**  <%=link_to "questions " ,:action=>"index" %>

i want pass id value controller app/post_controller.rb

please tell how access value also.

you can this:

<%= link_to "questions", :action => "index", :id => 1 %>

and more readable version:

<%= link_to "questions", questions_path, id: 1 %>

however, there's propably better way want achieve. if want link question, should this: first retrieve question object in controller this:

@question = question.find(2) # or params[:id]

and in view this:

<%= link_to "question", @question %>
