[英]Rails_admin gem filter has_many through association
I'd like to be able to use the "Add Filter" dropdown so admins can search for posts that have been flagged a particular name. 我希望能够使用“添加过滤器”下拉菜单,以便管理员可以搜索已被标记为特定名称的帖子。
My Post model 我的帖子模型
class Post < ActiveRecord::Base
belongs_to :user
has_many :post_flags
has_many :flags, through: :post_flags
config/initializers/rails_admin.rb 配置/初始化/ rails_admin.rb
config.model 'Post' do
exclude_fields :rank, :embedded_url, :attached_picture, :updated_at
object_label do
"#{bindings[:post].user.name}"
end
list do
field :text_content
field :created_at
field :user_id
field :likes_number
field :post_flags
end
end
I've tried adding "searchable" to the field :post_flags to no avail. 我尝试将“可搜索”添加到字段:post_flags无济于事。 Any help would be much appreciated. 任何帮助将非常感激。
I'm currently trying to work through a similar problem. 我目前正在尝试解决类似的问题。
Adding the following to your rails admin config should allow you to add a post_flag filter: 将以下内容添加到rails admin配置中,应该可以添加post_flag过滤器:
field :post_flags do
searchable :name
end
However, you will get an SQL error when when you try to use the search filter. 但是,当您尝试使用搜索过滤器时,会出现SQL错误。
