ransack_alias 未在查询中执行任何操作

ransack_alias not doing anything in query

我将 Ransack 用于我的搜索表单,并且我正在尝试使用 ransack_alias 来缩短查询。但是,当我执行搜索时,别名字段根本不会过滤查询。我已将我的表单简化为只有一个简单的别名,但它似乎不起作用。

用户模型

class User < ActiveRecord::Base
  ransack_alias :ec, :email_cont
end

index.html.haml

= search_form_for @q, url: users_path, html: {method: :get} do |f|
  = f.label :ec
  = f.search_field :ec
  = f.submit 'Search'

如果我在控制器中放置一个断点:

>> User.count
10

>> User.ransack({email_cont: "test@email.com"}).result.count
(93.8ms)  SELECT COUNT(*) FROM "users" WHERE ("users"."email" ILIKE '%test@email\.com%')
1

>> params[:q]
{"ec" => "test@email.com"}

>> User.ransack(params[:q]).result.count
(28.4ms)  SELECT COUNT(*) FROM "users"
10

>> User._ransack_aliases
{"ec" => "email_cont"}

我做错了什么?

ransack_alias 用于别名属性,但不是比较键。

class User < ActiveRecord::Base
  ransack_alias :e, :email
end

> User.ransack({'e_cont' => "user"}).result.count 
(0.2ms)  SELECT COUNT(*) FROM "users" WHERE ("users"."email" LIKE '%user%')
