Question

How to pass parameter via MVC using link_to method?

View:

How to use link_to method to use remove_tag action?

 issues_controller.rb def remove_tag(parameter) @issue.remove_it(parameter) end 

issue.rb

  def remove_it(parameter) self.users.delete(User.find(parameter)) end 

Answer 1

In the controller

 def remove_tag @issue.remove_it(params[:my_param]) end 

And in sight

 <%= link_to "Remove Tag", remove_tag_issue_path(issue, :my_param => "Hello world")%> 

Answer 2

In the view, use the following

 <%= link_to 'Remove Tag', remove_tag_issue_path(:issue => @issue)%> 

and in the controller

 def remove_tag @issue.remove_it(:issue => params[:issue]) end
