如何最好地 DRY will_paginate 选项 [英] How best to DRY will_paginate options

问题描述

我有 8 个控制器使用 will_paginate 对其索引页进行分页.我想覆盖每个上一个"和下一个"的默认值，而不必指定相同的选项 8 次.有没有办法只覆盖默认值一次(可能通过子类化 will_paginate).

I have 8 controllers using will_paginate to paginate their index pages. I'd like to override the defaults for "Previous" and "Next" on each without having to specify the same options 8 times. Is there a way to override the defaults only once (perhaps by subclassing will_paginate).

推荐答案

will_paginate 使用 I18n 所以你可以直接使用它.鉴于您使用英语作为默认语言环境，application.rb 中应出现以下行:

will_paginate uses I18n so you can just use that. Given you use English as the default locale the following line should be present in application.rb:

config.i18n.default_locale = :en

然后您可以通过将以下内容添加到 config/locales/will_paginate.en.yml 来更改分页链接的文本:

you can then change the text of the pagination links by adding the following to config/locales/will_paginate.en.yml:

en:
  will_paginate:
    previous_label: "← go back"
    next_label: "go forward →"

或者，您可以将它们添加到您的默认翻译文件中:config/locales/en.yml但我发现它很快变得难以处理.

Alternatively you can add them to your default translations file: config/locales/en.yml but I have found that it quickly becomes to large to handle.

注意:如果您使用其他语言环境，例如 es，为此您至少需要将 YAML 文件中的 en: 键替换为 es: 并且要简洁地命名您的文件，使用 config/locales/will_paginate.es.yml 或 config/locales/es.yml.

Note: If you use another locale, for instance es, for this to work you need to at least replace the en: keys within the YAML files to es: and to be concise about naming your files, use either config/locales/will_paginate.es.yml or config/locales/es.yml.
