Double render error rails

Question

Not sure how its possible to get this error :

AbstractController::DoubleRenderError users#create

When in my controller I got this code :

Answer 1

I suppose redirect_to signup_path is returning either nil or false, thus your and return is not being executed.

You can fix this many ways, the simplest is replace

redirect_to signup_path and return

by

redirect_to signup_path
return

Yet, I suggest you to do a bigger change. Try changing this

if @profile.nil? || current_user.nil? || @profile.user.nil?
  sign_out
  redirect_to signup_path and return
end

if @profile.new_record?
  render 'new' and return
else
  redirect_to more_questions_path and return
end

By

if @profile.nil? || current_user.nil? || @profile.user.nil?
  sign_out
  redirect_to signup_path
elsif @profile.new_record?
  render 'new'
else
  redirect_to more_questions_path
end

This way it is clear that only one path can be taken, without relying on return.
