Auto includes error

[malomalo]

Some controllers don't have a model and will generate the following error:

ActionView::Template::Error: undefined method 'model_name' for nil:NilClass from:

standardapi/lib/standard_api/controller.rb

Line 292 in caaf52d

@includes = nested_includes(model, params[model.model_name.singular].to_unsafe_h).merge(@includes)
