Ruby on Rails链接语法

Question

How do I use the link_to method, to utilize the remove_tag action?

issues_controller.rb

  def remove_tag
     @issue.remove_it
  end

issue.rb

  def remove_it
      self.users.delete(User.find(1))
   end

Answer 1

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

or

<%= link_to "Remove Tag", [:remove_tag, @issue] %>

And remove_tag action should be presented in routes as member for issue resources

Answer 2

It depends on how you have set your routes. You might need to use a named route for that action as it is not a standard resource route.

I suggest you read this:

http://guides.rubyonrails.org/routing.html

lint_to uses whatever is defined in routing
