ruby on rails link_to delete method not working


I am trying to delete a post using the code below:

<%= link_to 'Destroy', post, :method => :delete, :onclick => "return confirm('Are you sure you want to delete this post?')" %>

which does not work... it simply redirects me back to the post (posts/:id}

however, if i use the following code it works

<%= button_to 'Destroy', post, method: :delete, :onclick => "return confirm('Are you sure you want to delete this post?')" %>

is it possible to make link_to behave as button_to in this case?

EDIT: destroy controller function

  def destroy
    @post = Post.find(params[:id])
    @post.destroy

    respond_to do |format|
      format.html { redirect_to posts_url }
      format.json { head :no_content }
    end
  end

log when i click the destroy button:

routes:

  devise_for :users

  resources :users

  resources :posts

  match '/about' => 'about#index'

  # You can have the root of your site routed with "root"
  # just remember to delete public/index.html.
  root :to => 'index#index'

  # See how all your routes lay out with "rake routes"

  # This is a legacy wild controller route that's not recommended for RESTful applications.

Solution

  • Solution:

    I had commented out this from application.js when i created the project

    // This is a manifest file that'll be compiled into application.js, which will include all the files
    // listed below.
    //
    // Any JavaScript/Coffee file within this directory, lib/assets/javascripts, vendor/assets/javascripts,
    // or vendor/assets/javascripts of plugins, if any, can be referenced here using a relative path.
    //
    // It's not advisable to add code directly here, but if you do, it'll appear at the bottom of the
    // the compiled file.
    //
    // WARNING: THE FIRST BLANK LINE MARKS THE END OF WHAT'S TO BE PROCESSED, ANY BLANK LINE SHOULD
    // GO AFTER THE REQUIRES BELOW.
    //
    //= require jquery
    //= require jquery_ujs
    //= require_tree .
    

    so re-adding it in solved the problem
