我有两个问题。我如何翻译表单：a) 标签 b) Form ValidationErrors ？

forms.py

from django import forms
from django.db.models import Max, Min
from .models import Application, FlowRate, WaterFilterSubType, Fineness, Dirt
from .models import DirtProperties, Flange

class InputDataWaterForm(forms.Form):
    '''Application'''
    choices = list(Application.objects.values_list('id','application'))
    application = forms.ChoiceField(choices = choices, initial="1", label="Specify application:")
    ....

    def clean(self):
        cleaned_data = super(InputDataWaterForm, self).clean()
        application = cleaned_data.get('application')
    ...

        '''OTHER CONDITIONS if not flowrate ...'''
        if not (flowrate or pressure or dirt or dirtproperties or
            application or fineness or temperature or
            flange or atex or aufstellung or ventil):
            raise forms.ValidationError('PLEASE ENTER THE REQUIRED INFO')

如何翻译数据库中表的内容？所有记录，例如。必须翻译表中的产品名称。

models.py

from django.db import models

'''FILTER PROPERTIES LIKE COLOR'''
class FP_sealing(models.Model):
    value = models.CharField('Material Sealing', max_length=10)
    descr = models.CharField('Description', max_length=200, default="")
    def __str__(self):
        return("Seal: " + self.value)

谢谢

翻译通常使用Django 的翻译框架完成。对于急切的翻译，一个使用gettext，对于惰性翻译（应该在渲染时计算的翻译），一个使用gettext_lazy. 例如，您可以使用以下方式翻译您的应用程序：

from django import forms
from django.db.models import Max, Min
from .models import Application, FlowRate, WaterFilterSubType, Fineness, Dirt
from .models import DirtProperties, Flange
from django.utils.translation import gettext_lazy as _

class InputDataWaterForm(forms.Form):
    '''Application'''
    choices = list(Application.objects.values_list('id','application'))
    application = forms.ChoiceField(choices = choices, initial="1", label=_("Specify application:"))
    # …

    def clean(self):
        cleaned_data = super(InputDataWaterForm, self).clean()
        application = cleaned_data.get('application')
        # …

        '''OTHER CONDITIONS if not flowrate …'''
        if not (flowrate or pressure or dirt or dirtproperties or
            application or fineness or temperature or
            flange or atex or aufstellung or ventil):
            raise forms.ValidationError(_('PLEASE ENTER THE REQUIRED INFO'))

对于模型中的选择值，如文档中所述：

from django.utils.translation import gettext_lazy as _

class Student(models.Model):

    class YearInSchool(models.TextChoices):
        FRESHMAN = 'FR', _('Freshman')
        SOPHOMORE = 'SO', _('Sophomore')
        JUNIOR = 'JR', _('Junior')
        SENIOR = 'SR', _('Senior')
        GRADUATE = 'GR', _('Graduate')

    year_in_school = models.CharField(
        max_length=2,
        choices=YearInSchool.choices,
        default=YearInSchool.FRESHMAN,
    )

    def is_upperclass(self):
        return self.year_in_school in {
            self.YearInSchool.JUNIOR,
            self.YearInSchool.SENIOR,
        }

然后你可以运行makemessages命令 [Django-doc]来制作翻译文件：

django-admin makemessages --locale=de_DE

然后 Django 将创建*.po文件，您可以在其中定义您定义的字符串的翻译。

然后可以使用compilemessages命令 [Django-doc]将这些翻译文件编译成*.mo文件：

django-admin compilemessages --locale=de_DE
