我尝试创建一个包含2个参数的过滤器 - 一个用无线电输入编辑,另一个用一组复选框编辑。我有2个模型由has_and_belongs_to_many
关联连接。我需要创建一个带有嵌套模型ID的scope
。例如,我有网址:
/catalog?category=1&feature=1,2
范围必须返回带有id
s 1和2
如何创建这样的范围?
我的分类型号:
class Lamp < ActiveRecord::Base
belongs_to :category, inverse_of: :lamps
has_and_belongs_to_many :features
validates :name, :preview, :small_preview, presence: true
scope :visibles, -> { where(hided: false) }
scope :category_filter, -> (category_id) { where(category_id: category_id) if category_id.present? }
end
我的功能模型:
class Feature < ActiveRecord::Base
has_and_belongs_to_many :lamps
validates :name, presence: true
validates :name, uniqueness: true
mount_uploader :ico, FeatureIcoUploader
scope :visibles, -> { where(hided: false) }
scope :ordered, -> { order(prior: :asc, id: :desc) }
def display_name; name end
end
答案 0 :(得分:0)
请尝试此操作并确保您的中间表名称正确无误(:features_lamps或lamps_features)
$config['resourceTypes'][] = array(
'name' => 'Images',
'directory' => 'images',
'maxSize' => 2000,
'allowedExtensions' => 'bmp,gif,jpeg,jpg,png',
'deniedExtensions' => '',
'backend' => 'default'
);
