I have two questions. How can I translate in forms: a) labels 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')
How can I translate content of a table in a database? All records eg. product names in a table must be translated.
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
Translations are normally done with Django's translation framework . For eager translations, one uses gettext
, for lazy translations (translations that should be calculated when rendered), one uses gettext_lazy
. You can for example translate your application with:
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
class InputDataWaterForm(forms.Form):
'''Application'''
choices = list(Application.objects.values_list('id','application'))
application = forms.ChoiceField(choices = choices, initial="1", label=)
# …
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()
For choice values in models, as is specified in the documentation :
from django.utils.translation class Student(models.Model): class YearInSchool(models.TextChoices): FRESHMAN = 'FR', SOPHOMORE = 'SO', JUNIOR = 'JR', SENIOR = 'SR', GRADUATE = 'GR', 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:
django-admin --locale=de_DE
Django will then make *.po
files where you can define the translations for the strings you defined.
Then you can use the compilemessages
command [Django-doc] to compile these translation files to *.mo
files:
django-admin --locale=de_DE
