I have Item Model
class Item < ActiveRecord::Base
has_many :images, dependent: :destroy
accepts_nested_attributes_for :images, :allow_destroy => true
end
and Image Model
class Image < ActiveRecord::Base
belongs_to :item
has_attached_file :picture, :styles => {:medium => "600x600>", :thumb => "100x100>"}, :default_url => "/images/:style/missing.png"
end
And in the controller, the strong parameters go
def item_params
params.require(:item).permit(:name, :description, :price, images_attributes: [:picture, :_destroy])
end
just as the Cocoon READM says.
So the basic idea is that an Item has several Images, which in turn have this paperclip field picture
. Then the form is being rendered with Coccon
#views/admin/items/new.html.erb
<div class="field">
<div class="ui teal label">Imagen</div>
<%= f.fields_for :images do |image| %>
<%= render partial: 'image_fields', :f => image %>
<% end %>
</div>
#views/admin/items/_image_fields.html.erb
<div class="nested-fields">
<%= f.file_field :image, :class => "add-image-field" %>
<%= link_to_remove_association "Eliminar", f, :class => "ui red mini button" %>
</div>
In the view everything seems to work fine, but then looking at the parameters sent to the controller, something is wrong:
Parameters: {"utf8"=>"✓",
"authenticity_token"=>"AIogvRQuKNrAAOjM7YsnVQx7j2MwZ1VC3LiZy0cDDrU=",
"item"=>{
"name"=>"",
"description"=>"",
"price"=>"12345",
"images_attributes"=>{
"1394577880921"=>{
"image"=>#<ActionDispatch::Http::UploadedFile:0x00000003182718 @tempfile=#<Tempfile:/tmp/RackMultipart20140311-27326-19i0obp>, @original_filename="blue-diamond-rings.jpg", @content_type="image/jpeg", @headers="Content-Disposition: form-data; name=\"item[images_attributes][1394577880921][image]\"; filename=\"blue-diamond-rings.jpg\"\r\nContent-Type: image/jpeg\r\n">, "_destroy"=>"false"}}},
"commit"=>"Crear"}
What's that weird signature after images_attributes? It's ruining the Item saving process.
Thanks for any pointer!
