Rails 4.0.0 to 4.1.0 upgrade cause wrong number of arguments error

Question

I've upgraded from Rails 4.0.0 to Rails 4.1.0 .

Now I got this error:

wrong number of arguments (1 for 0)

 @courses = Course.all(:conditions =>{ :lecturer_id => session[:user_id] })

How can I fix it?

Answer 1

You should use Active Record's .where() method:

@courses = Course.where(lecturer_id: session[:user_id])
