Я сейчас схожу с ума.
У меня есть 2 модели: проект и скриншот:
create_table "projects", :force => true do |t|
t.string "name"
t.text "description"
t.boolean "isactive"
t.datetime "created_at", :null => false
t.datetime "updated_at", :null => false
t.string "slug"
t.string "logo"
t.string "teaser"
end
add_index "projects", ["slug"], :name => "index_projects_on_slug"
create_table "screenshots", :force => true do |t|
t.integer "project_id"
t.string "image"
t.datetime "created_at", :null => false
t.datetime "updated_at", :null => false
end
Модель проекта выглядит как
class Project < ActiveRecord::Base
attr_accessible :name, :description, :isactive, :slug, :logo, :teaser, :screenshots_attributes
scope :isactive, :conditions => ["isactive = ?",true]
mount_uploader :logo, LogoUploader
extend FriendlyId
friendly_id :name, use: [:slugged, :history]
has_many :screenshots
accepts_nested_attributes_for :screenshots
end
и модель скриншота
class Screenshot < ActiveRecord::Base
belongs_to :project, :polymorphic => true
mount_uploader :screenshots, ScreenshotUploader
end
Screenshot Uploader в настоящее время не редактируется:
# encoding: utf-8
class ScreenshotUploader < CarrierWave::Uploader::Base
# Include RMagick or MiniMagick support:
# include CarrierWave::RMagick
# include CarrierWave::MiniMagick
# Choose what kind of storage to use for this uploader:
storage :file
# storage :fog
# Override the directory where uploaded files will be stored.
# This is a sensible default for uploaders that are meant to be mounted:
def store_dir
"uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
end
# Provide a default URL as a default if there hasn't been a file uploaded:
# def default_url
# "/images/fallback/" + [version_name, "default.png"].compact.join('_')
# end
# Process files as they are uploaded:
# process :scale => [200, 300]
#
# def scale(width, height)
# # do something
# end
# Create different versions of your uploaded files:
# version :thumb do
# process :resize_to_fit => [300, 150]
# end
# Add a white list of extensions which are allowed to be uploaded.
# For images you might use something like this:
# def extension_white_list
# %w(jpg jpeg gif png)
# end
# Override the filename of the uploaded files:
# Avoid using model.id or version_name here, see uploader/store.rb for details.
# def filename
# "something.jpg" if original_filename
# end
end
А сейчас я пытаюсь добавить скриншоты из activeadmin, используя эту форму
form do |f|
f.inputs "Project Details" do
f.input :name
f.input :logo, :as => :file, :hint => f.template.image_tag(f.object.logo.url)
f.input :teaser
f.input :description
f.input :isactive
f.has_many :screenshots do |s|
s.input :image, :as => :file
end
end
f.buttons
end
Но все, что я получаю, это:
NoMethodError (undefined method `screenshots_changed?' for #<Screenshot:0xc940cd0>):
Я играл с этим последние часы, но ничего, что я пробовал, не сработало: (
Есть предложения?
