Why does devise me redirect me to /users instead of /users/edit when my account update fails?

The problem is like this:

If I use the default registration controller I get redirected:

• /users/edit to root when user update succeeds


• /users/edit to /users when update fails

Because the default controller update action looks like this:

if resource_updated
  sign_in resource_name, resource, bypass: true
  respond_with resource, location: after_update_path_for(resource)
else
  clean_up_passwords resource
  respond_with resource
end

after_update_path_for is set by default to root

If update fails I get the devise error messages and hasError div wrappers for the fields with error

In my registrations controller in the edit action I attribute values to a variable @myvar={2, 3}

This variable is used in the registrations_edit view

Whenever user update fails I get error no method .each for nil for my @myvar

How should I declare my view variables such that they are accessible even when update form fails?!

I have tried:

Forcing the controller to redirect to edit view no matter what:

if resource_updated
  sign_in resource_name, resource, bypass: true
  redirect_to edit_user_registration_path
else
  clean_up_passwords resource
  redirect_to edit_user_registration_path
end

This created problems because devise validations do not work anymore
