wrong number of arguments (4 for 1..3)

i'm struggling to understand why this is happen with destroy method since everything on controller and routes is ok!

if someone passed through this way please could give me a hint?

Routes

 resources :users, :as => "" do
    resources  :sections, :only => [:new, :create, :destroy, :index] 
  end

Controller

def destroy
    @section = Section.find(params[:id])
    @section.destroy
    redirect_to sections_url
    flash[:notice] = "Section deleted" 
  end

View

<%= render :partial => "section", :collection => @sections %>

Partial

<%= link_to  section.name, section_path(current_user, section) %> 
<%= button_to 'Remove', current_user, section, :data => { :confirm => 'Confirm?' }, :class=> "buttom",  method: :delete %>

codeit, Stefan did what you guys said but did not work, so i tried the path instead and worked!

<%= button_to 'Remove', section_path(current_user, section), :data => { :confirm => 'Confirm?' }, :class=> "button",  method: :delete %>

The problem seems to be this method call:

button_to 'Remove', current_user, section, :data => { :confirm => 'Confirm?' }, :class=> "buttom",  method: :delete

The pair current_user and section has to been passed as an array:

button_to 'Remove', [current_user, section], confirm: 'Confirm?', class: "buttom",  method: :delete

Your button_to helper arguments are wrong.

Try this:

  <%= button_to 'Remove', {:action => :destroy, :user => current_user, :id => section}, {:data => { :confirm => 'Confirm?' }, :class=> "buttom",  method: :delete} %>

That error means that some function takes 1 to 3 arguments, but you gave to it 4 arguments.

Please see the row number in the error and look up the function, then open documentation and look up how to use that function. Often functions works differently as instance methods and class methods.
