Django在模型保存上转换数据

Question

I need to translate the data automatically in the django admin.

I'm currently translating all the static text manually using django rosetta, to simplify the translation. What I need to do is translate all the data automatically using Microsoft translator API in the admin interface.

Lets assume I have a function that do the translation. Should I use django-modeltranslation with the translation function and override the save function for each model?

Any tips, modules, or code snippets that can help.

If the language you need to translate to and translate from is fixed, as in you don't intend the user to input data in several languages, then you could translate the data in your model save method:

class ModelName(models.Model):

    data = models.CharField()

    def save(self):
        """ Extension of parent save method """

        for name in ModelName._meta.get_all_field_names():
            field = getattr(name, ModelName, None)
            field = translate(field)

        super(ModelName, self).save()

Another option would be to do the translation in the input validation of the data, if it is a form:

class ModelNameForm(forms.Form):

    data = forms.CharField()

    def clean_data(self):
        data = self.cleaned_data['data']
        return translate(data)
