Pyramid TranslationString 不适用于 json 渲染器 [英] Pyramid TranslationString not working on json renderer

问题描述

在我在金字塔应用程序中进行的测试中，我尝试通过 JSON 发送可翻译文本，但翻译无效.在文件的开头我导入了翻译字符串函数:

In a test I am doing in a pyramid application, I am trying to send a translatable text via JSON, but the translation is not working. At the beginning of the file I am importing the translation string function:

from pyramid.i18n import TranslationString as _

然后考虑以下代码:

@view_config(route_name='transtest', renderer='json')
def transtest_view(request):
    return { 'myvar': _('temp-test', default='Temporary test', domain='myapp') }

但我得到的是:

{"myvar": "temp-test"}

请注意，如果我将渲染器更改为测试模板，我会执行以下操作:

Note that if I change the renderer to a test template I did as follows:

@view_config(route_name='transtest', renderer='../templates/transtest.pt')
...

然后文本被正确翻译(请注意，我已经初始化了目录，更新了它们，编译了它们等)

then the text gets translated correctly (note that I already initialized the catalogs, updated them, compiled them, etc.)

这让我觉得 TranslationString 类在json"渲染器中无法正常工作?如果是这样，我该如何通过 JSON 发送可翻译的字符串?

This made me think that the TranslationString class does not work right in a 'json' renderer? If so, how can I make to send a translatable string via JSON?

提前致谢

推荐答案

您需要明确地翻译您的消息字符串，使用 get_localizer() 和 Localizer.translate():

You need to explicitly translate your message string, using get_localizer() and Localizer.translate():

from pyramid.i18n import get_localizer

@view_config(route_name='transtest', renderer='json')
def transtest_view(request):
    message = _('temp-test', default='Temporary test', domain='myapp')
    return {'myvar': get_localizer(request).translate(message)}

通常，模板会为您处理这些步骤，但对于 JSON，您需要自己完成这些步骤.

Normally, templates take care of these steps for you, but for JSON you'll need to do so yourself.

您可能想要定义一个 TranslationStringFactory 用于您的项目，并重用它来生成您的消息字符串.将以下内容添加到您的项目中:

You probably want to define a TranslationStringFactory for your project, and reuse that to produce your message strings. Add the following to your project:

from pyramid.i18n import TranslationStringFactory

myapp_domain = TranslationStringFactory(domain='myapp')

然后使用:

from my.project import myapp_domain as _

# ....

message = _('temp-test', default='Temporary test')
