20,485 PointsAdding Attachments to Other Models
Has anyone had success adding the document class to other models? I'm trying to do it with a polymorphic association, like:
document.rb
belongs_to :attachable, polymorphic: true
lesson.rb (another model)
has_many :documents, as: :attachable, dependent: :destroy
Then trying in my lesson form to add this:
<%= f.fields_for :document do |document_fields| %>
<%= document_fields.input :attachment, as: :file %>
<% end %>
I'm getting multiple errors. Anyone done this, or know of a way to do this? I want to be able to attach files to other models, so a polymorphic association is best.
I've added columns to the document model
attachable_id: integer
attachable_type:string
Any ideas or places to look would be great! I'm struggling quite a bit here. Thanks in advance!
