[英]Django Translation Internationalization and localization: forms, models, tables
I have two questions.我有两个问题。 How can I translate in forms: a) labels b) Form ValidationErrors?如何在 forms 中翻译:a) 标签 b) 表单验证错误?
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')
How can I translate content of a table in a database?如何翻译数据库中表的内容? All records eg.所有记录,例如。 product names in a table must be translated.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)
Thank you谢谢
Translations are normally done with Django's translation framework .翻译通常使用Django 的翻译框架完成。 For eager translations, one uses gettext
, for lazy translations (translations that should be calculated when rendered), one uses gettext_lazy
.对于急切的翻译,使用gettext
,对于惰性翻译(应在渲染时计算的翻译),使用gettext_lazy
。 You can for example translate your application with: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'))
For choice values in models, as is specified in the documentation :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, }
Then you can run the makemessages
command [Django-doc] to make translation files: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
Django will then make *.po
files where you can define the translations for the strings you defined. Django 然后将生成*.po
文件,您可以在其中定义您定义的字符串的翻译。
Then you can use the compilemessages
command [Django-doc] to compile these translation files to *.mo
files:然后您可以使用compilemessages
命令 [Django-doc]将这些翻译文件编译为*.mo
文件:
django-admin compilemessages --locale=de_DE
