Ransack 搜索和翻译 [英] Ransack search and translations

问题描述

我正在尝试对与翻译表有关联的模型进行搜查.

I´m trying to make ransack work on a model that has an association with a translation table.

翻译由 globalize gem 管理.

Translations are managed by globalize gem.

问题是当我尝试在 :name 列的模型表中使用 ransack 进行搜索时，它什么也没显示，因为 :name 信息存储在另一个表中.

The problem is when I try to search with ransack in model table in :name column, it shows nothing because the :name information is stored in another table.

任何线索如何在关联翻译表中进行搜查搜索?我知道有可能使用 ransackers，但我不知道要放入哪些代码.

Any clues how can I make ransack search in the association translation table? I know there is the possibility of using ransackers, but I have no idea which code to put in them.

推荐答案

Globalize 给你一个 with_translations 喜欢:

Globalize gives you a class method of with_translations like:

User.with_translations('en')

所以你可以在你的模型上设置你自己的范围，利用这个优势:

And so you can set up your own scope on your model that takes advantage of this like:

def self.with_translated_name(name_string)
  with_translations(I18n.locale).where('user_translations.name' => name_string)
end

然后你可以在你的ransackable_scopes数组中公开这个范围 在相关模型中，例如:

Then you can expose this scope in your ransackable_scopes array in the model in question, like:

private

def self.ransackable_scopes   
  %i(with_translated_name) 
end

有了这个，你应该能够做到:

With that in place you should be able to do:

User.ransack({ with_translated_name: "John" })
