Rails Helper method : wrong number of arguments (1 for 2) -

-

i'm having trouble helper method on rails app. method has 2 arguments , when try call it, error says : wrong number of arguments (2 1).

def toggle_like_button(post, user)     if user.flagged?(post, :like)         link_to "unlike", like_post_path(post)     else         link_to "like", like_post_path(post)     end end

in view :

<%= toggle_like_button(post, current_user) %>

current_user , post both set, don't understand why raised error, did forget inside brackets in method? in advance!
