[resolved]ArgumentError in controller wrong number of arguments

I'm trying to understand what is happening here

When I start the rails server for my app. I'm getting an 

ArgumentError in StaticPagesController#help_seller_signup
wrong number of arguments (0 for 1)

StaticPagesController#help_seller_signup
def help_seller_signup
end

help_seller_signup.html.erb
<%= link_to "Sign up", sellersignup_path, class: "btn btn-lg  btn-primary" %>

routes.rb
get 'help_seller_signup' => 'static_pages#help_seller_signup'```

application trace
pp/models/user.rb:3:in `<class:User>'
app/models/user.rb:1:in `<top (required)>'
app/helpers/sessions_helper.rb:23:in `current_user'
app/helpers/sessions_helper.rb:35:in `logged_in?'
app/views/static_pages/home.html.erb:15:in `_app_views_static_pages_home_html_erb__565785473__622525708'

The page was working before. I know I made a change that caused it.

The source is pointing to the def destroy(id) default method. Which is puzzling as the app shouldn't be deleting anything on the front page.

It's pretty interesting though. I have't ran into this with the to-do app or anything and I wonder if its because I'm experimenting with a more complex relationship. User has a has_many and a has_one relationships.

Found the answer, in the user controller I had has_many :bookings, dependent: destroy rather than has_many :bookings, dependent: :destroy (note the : before the destroy in the second)
