I would like to make my app upload multiple files with Shrine, but one doc suggests two file_fields whereas the other suggests only one. After posting a question to their discourse forum, it was suggested that I hide the one named files[]. Whether I do this or not, the first file_field always fails to render. Why does this field not display?
<%= form_for @item, html: { enctype: "multipart/form-data" } do |f| %>
<%= f.fields_for :photos do |i| %>
<%= i.label :image %>
<%= i.hidden_field :image, value: i.object.cached_photos_data, class: "upload-data" %>
<%= i.file_field :image, class: "upload-file" %> /// why is this not rendering?
<% end %>
<%= file_field_tag "files[]", multiple: true %> // what purpose does this one serve?
<%= f.text_field :title %>
<%= f.submit "Submit" %>
<% end %>
Models:
class Item < ApplicationRecord
has_many :photos, as: :imageable, dependent: :destroy
end
class Photo < ApplicationRecord
include ImagesUploader::Attachment(:image)
belongs_to :imageable, polymorphic: true
validates_presence_of :image
end
Controller:
class ItemsController < ApplicationController
def new
@item = current_user.items.new
end
def create
@item = current_user.items.create(item_params)
@item.save
end
private
def item_params
params.require(:item).permit(:title, photos_attributes: { image: [] })
end
end
