Question

如何为字段标签，帮助文本等实施国际化支持。字段的标准乘法似乎不起作用例如文档中提供的用于创建联系表格的示例。我试图为其他语言添加额外的字段（文档中介绍的第一种方法）

  from django.db import models

  from wagtail.core.models import Page
  from modelcluster.fields import ParentalKey
  from wagtail.admin.edit_handlers import (
    FieldPanel, FieldRowPanel,
    InlinePanel, MultiFieldPanel
  )

  from wagtail.core.fields import RichTextField
  from wagtail.contrib.forms.models import (
    AbstractEmailForm, AbstractForm, AbstractFormField
  )
  from wagtail.contrib.forms.edit_handlers import FormSubmissionsPanel
  from dimaplus.languages import TranslatedField
  # Create your models here.

  class FormField(AbstractFormField):
    page = ParentalKey(
        'FormPage',
        on_delete=models.CASCADE,
        related_name='form_fields',
    )
    label_fa = models.CharField(max_length=255)
    label_ru = models.CharField(max_length=255)
    label_ar = models.CharField(max_length=255)

    tr_label_tag = TranslatedField(
      'label',
      'label_fa',
      'label_ar',
      'label_ru',
    )
    panels = AbstractFormField.panels + [
        FieldPanel('label_fa'),
        FieldPanel('label_ru'),
        FieldPanel('label_ar'),
    ]
  class FormPage(AbstractEmailForm, Page):

    intro = RichTextField(blank=True)
    intro_fa = RichTextField(blank=True)
    intro_ar = RichTextField(blank=True)
    intro_ru = RichTextField(blank=True)

    thank_you_text = RichTextField(blank=True)
    thank_you_text_fa = RichTextField(blank=True)
    thank_you_text_ar = RichTextField(blank=True)
    thank_you_text_ru = RichTextField(blank=True)

    # 'body',
    # 'body_fa',
    # 'body_ar',
    # 'body_ru',
    tr_intro = TranslatedField(
        'intro',
        'intro_fa',
        'intro_ar',
        'intro_ru'
    )
    tr_thank_you_text = TranslatedField(
        'thank_you_text',
        'thank_you_text_fa',
        'thank_you_text_ar',
        'thank_you_text_ru'
    )

    content_panels = AbstractEmailForm.content_panels + [
        FormSubmissionsPanel(),
        FieldPanel('intro_fa', classname='full'),
        InlinePanel('form_fields', label="Form fields"),
        FieldPanel('thank_you_text_fa', classname="full"),
        MultiFieldPanel([
            FieldPanel('intro'),
            FieldPanel('thank_you_text'),
            FieldPanel('intro_ar'),
            FieldPanel('thank_you_text_ar'),
            FieldPanel('intro_ru'),
            FieldPanel('thank_you_text_ru'),
        ]),
        MultiFieldPanel([
            FieldRowPanel([
                FieldPanel('from_address', classname="col6"),
                FieldPanel('to_address', classname="col6"),
            ]),
            FieldPanel('subject'),
        ], "Email"),
    ]

在文档中简单地给出了'TranslatedField'类：

from django.utils import translation
from django.utils.translation import gettext_lazy as _

#translation class
class TranslatedField:
    def __init__(self,
                 en_field,
                 fa_field,
                 ar_field,
                 ru_field):
        self.en_field = en_field
        self.fa_field = fa_field
        self.ar_field = ar_field
        self.ru_field = ru_field

    def __get__(self, instance, owner):
        lang = translation.get_language()
        if lang == 'fa':
            return getattr(instance, self.fa_field)
        elif lang == 'ar':
            return  getattr(instance, self.ar_field)
        elif lang == 'ru':
            return  getattr(instance, self.ru_field)
        else:
            return getattr(instance, self.en_field)

Answer 1

from django.utils.translation import ugettext_lazy as _

class FormPage(AbstractEmailForm, Page):
    intro = models.CharField(
        max_length=255, 
        verbose_name=_('Introduction')
        help_text=_('The first paragraph of the page.')
    )

以防有人偶然发现此问题。可以使用文档中的示例执行此操作。您必须将label字段本身用于翻译，因为这是wagtail用来构建表单的字段。只需使用翻译字段覆盖它即可。

class FormField(AbstractFormField):
    label_en = models.CharField(max_length=250)
    label_de = models.CharField(max_length=250)
    label_fr = models.CharField(max_length=250)
    label_ru = models.CharField(max_length=250)

    label = TranslatedField(
        'label_en',
        'label_de',
        'label_fr',
        'label_ru'
    )

    content_panels = AbstractEmailForm.content_panels + [                 
        FieldPanel('label_en'),
        FieldPanel('label_de'),
        FieldPanel('label_fr'),
        FieldPanel('label_ru'),
    ]

与帮助文本字段相同。这些是课程使用的字段：

panels = [
    FieldPanel('label'),
    FieldPanel('help_text'),
    FieldPanel('required'),
    FieldPanel('field_type', classname="formbuilder-type"),
    FieldPanel('choices', classname="formbuilder-choices"),
    FieldPanel('default_value', classname="formbuilder-default"),
]
