rails_admin multiple image uploading?

Question

I want to make something like gallery of photos for each of my product in rails_admin.

But for different products I want to add different amount of photos.

So, I've got my Product model with has_one :gallery association and my Gallery model with belongs_to :product association.

How can I have multiple fields in rails_admin model, when I don't know how many fields, will I need exactly?

Or how can I upload multiple files through Paperclip in rails_admin ?

Answer 1

You could use accepts_nested_attributes_for

class Photo < ApplicationRecord
   belongs_to :gallery, inverse_of: photos
   has_attached_file :image
end

class Gallery 
   has_many :photos
   accepts_nested_attributes_for :photos
end

And this would get you something like this:

Notice how you could have as many photos as you want.
