How to destroy polymorphic model? Method destroy missing argument

Im using this gem to add private messages to my application.

https://github.com/LTe/acts-as-messageable/blob/master/lib/acts-as-messageable/message.rb

I`m trying to add remove link to message.

So in my controller i have destroy action:

  def destroy
    @message = current_user.messages.with_id(params[:id])
    if @message.destroy
      flash[:notice] = "All ok"
    else
      flash[:error] = "Fail"
    end
  end

And in my view i have link: = link_to "Delete", message_path(message.id), :method => :delete

But when im trying to click link i receive: wrong number of arguments (0 for 1)

This is related with this question: Why delete method gives me wrong path? with

The problem is that you're getting all messages, so @message is really multiple messages. You probably want to do:

@message = Message.find(params[:id])

But this may be different for the gem. The gem's documentation has a section on deleting at the bottom of the readme.
