Question

我正在使用django-modeltranslation在DRF中翻译mo模型

所以我做了所有说django-modeltranslation的文档，并且它适用于模型字段

但是我无法获得Choicefield的翻译价值

from django.utils.translation import ugettext_lazy as _
class Product(models.Model):

PRODUCT_TYPES = (
    ('food', _('food')),
    ('wear', _('wear'))
)
name = models.CharField(verbose_name='Name', max_length=512, blank=True)
product_type = models.CharField('Type', choices=PRODUCT_TYPES, blank=True, null=True, max_length=16, default='food')

product_name之类的字段由django-modeltranslation翻译并可以正常工作

但是我总是在food中得到product_type

我运行makemessages和compilemessages

msgid "food"
msgstr "еда"

msgid "wear"
msgstr "одежда"

调用get_product_type_display无效

class ProductSerializer(serializers.ModelSerializer):
    date = serializers.DateTimeField(read_only=True, format='%d.%m.%Y %H:%M')
    product_type = serializers.SerializerMethodField()

    class Meta:
        model = Product
        fields = ('phone_number', 'name', 'total_bonus', 'card_number', 'id', 'count', 'date', 'product_type',
                  'category')

    def get_product_type(self, obj):
        return obj.get_product_type_display()

我找到了解决此问题的方法。需要使用：package com.company; import java.util.HashMap; import java.util.Map; public class Repository { private Map<Long, Product> product_repository = new HashMap<Long, Product>(); // TO DO: Implement while loops so program doesn't exit at the first error public void save_product(Long key, Product newProductMap){ try{ if (product_repository.containsValue(newProductMap)) { System.out.println("This product is already in the system." + "\nFor safety reasons, we cannot add the same product twice."); } else { product_repository.put(key, newProductMap); } } catch (Exception e) { System.out.println("System error. Consult the database administrator."); } } public void find_product(Long key){ try { if (product_repository.containsKey(key)) { System.out.println(product_repository.get(key)); } else { System.out.println("No matches were found for product id: " + key); } } catch (Exception e) { System.out.println("System error. Consult the database administrator."); } } // Overload public void find_product(String name) { try { if (product_repository.containsValue(name)) { System.out.println(product_repository.get(name)); product_repository.keySet().iterator().forEachRemaining(System.out::println); } else { System.out.println("No matches were found for product name: " + name); } } catch (Exception e) { System.out.println("System error. Consult the database administrator."); } } }

return _(obj.product_type)

使用get_FIELDNAME_display（）对象方法的序列化器：

attrs

DRF序列化器返回转换后的选择字段值
