Django，如何用[ORDER BY CONVERT（name USING gbk）ASC]查詢[

]我想用[ORDER BY CONVERT (name USING gbk) ASC]查詢，這樣foreignkey管理員更改/添加表單的列表可以按中文拼音排序，可能嗎？Django，如何用[ORDER BY CONVERT（name USING gbk）ASC]查詢[

DB：mysql的， Sample類是一擊（字符集表commoninfo的：utf8_general_ci）：

class CommonInfo(models.Model): 
    name = models.CharField(max_length=128) 
    def __str__(self): 
     return self.name 

class Personal(CommonInfo): 
    first_name = models.CharField(max_length=128,null=True, blank=True, default = None) 
    last_name = models.CharField(max_length=128,null=True, blank=True, default = None) 

class Profile(models.Model): 
    personal_info = models.ForeignKey(Personal, null=True, blank=True, default = None) 
    mobile = models.CharField(max_length=32,default='',null=True, blank=True)

我想在下面ProfileAdmin 2點的方法，但沒有作品

def formfield_for_foreignkey(self, db_field, request, **kwargs): 
    if db_field.name == "personal_info":  

     #raw_sql = 'SELECT id as commoninfo_ptr_id, name FROM share_commoninfo ORDER BY CONVERT (name USING gbk) ASC' 
     #raw_querySet = Personal.objects.raw(raw_sql) 
     #kwargs["queryset"] = raw_querySet 

     querySet = Personal.objects.extra(order_by=['CONVERT (name USING gbk)']) 
     kwargs["queryset"] = querySet 

     return super(ProfileAdmin, self).formfield_for_foreignkey(db_field, request, **kwargs) 

admin.site.register(models.Profile, ProfileAdmin)

FieldError: Cannot resolve keyword 'CONVERT (name USING gbk)' into field. Choices are: commoninfo_ptr, commoninfo_ptr_id, first_name, id, last_name, name, profile, Check fields/fieldsets/exclude attributes of class ProfileAdmin.

爲什麼需要' '轉換（名稱中使用GBK）''？ – doniyor

表的字符集是utf8_general_ci，它不能通過使用[ORDER BY chinese_data_field]，得到正確的（預期的）順序。看起來，要有中文拼音的預期順序 - 順序，我必須將表格轉換爲gbk，或者轉換訂單字段。 – alice

from django.db.models import Func, Value 

class Convert(Func): 
    def __init__(self, expression, transcoding_name, **extra): 
     super(Convert, self).__init__(
      expression, transcoding_name=Value(transcoding_name), **extra) 

    def as_mysql(self, compiler, connection): 
     self.function = 'CONVERT' 
     self.template = '%(function)s(%(expressions)s AS %(transcoding_name)s)' 
     return super(Conver, self).as_sql(compiler, connection)

用法：

queryset.order_by(Convert('name', 'gbk').asc())

非常感謝你，代碼工作得很好，我從文檔中學到了更多：） – alice
