Answer 1

You are setting up that route with a constraint
%w[profile_photo cover_photo].each do |croppable_image_name|
resrources
...
constraints: { name: croppable_image_name }
end
end
So you need to add name: to your route, so this should work:
stagers_stager_croppable_image_path(name: 'profile_photo')
However, since you are not using a specific route name on that each loop, calling it with name set to cover_photo will not work. I think you probably want to use a regex like
constraints: { name: /(cover|profile)_photo/ }
Try declaring your routes like this (sorry I messed up your style)
Rails.application.routes.draw do
namespace :stagers, path: 'stager' do
resource(:stager, path: 'profile', only: %i[edit update], path_names: { edit: '' }) do
resources(
:croppable_image,
controller: '/croppable_images',
path: '',
param: :name,
only: %i[edit update],
path_names: {
edit: ''
},
defaults: {
record_type: 'Stager'
},
constraints: {
name: /(cover|profile)_photo/
}
)
end
end
end
