Steps to Reproduce

Steps to reproduce the behavior:

1. Add this configuration config.buttons_on_form_footers = true
2. Go to new record which has belongs_to field
3. Click on 'Create new $parent_model' link under the belongs_to selector
4. See the error No route matches {:action=>"new", :controller=>"avo/$parent_model"}

Expected behavior & Actual behavior

It should open a new modal window with new parent record form. It shows no route error instead.

Models and resource files

This is enough to reproduce the issue as long as config.buttons_on_form_footers = true is set in config/initializers/avo.rb:

./bin/rails g scaffold author name:string
./bin/rails g scaffold post title:string content:text author:references
