Django 翻譯國際化和本地化：forms，模型，表格

Question

我有兩個問題。 如何在 forms 中翻譯：a) 標簽 b) 表單驗證錯誤？

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')

如何翻譯數據庫中表的內容？ 所有記錄，例如。 必須翻譯表中的產品名稱。

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)

謝謝

翻譯通常使用Django 的翻譯框架完成。 對於急切的翻譯，使用gettext ，對於惰性翻譯（應在渲染時計算的翻譯），使用gettext_lazy 。 例如，您可以使用以下方式翻譯您的應用程序：

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'))

對於模型中的選擇值，如文檔中所述：

 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, }

然后你可以運行makemessages命令 [Django-doc]來制作翻譯文件：

django-admin makemessages --locale=

Django 然后將生成*.po文件，您可以在其中定義您定義的字符串的翻譯。

然后您可以使用compilemessages命令 [Django-doc]將這些翻譯文件編譯為*.mo文件：

django-admin compilemessages --locale=
