不存在django管理匹配查询。

Question

编辑我认为这与django-fsm有关，请看我为各州编写的代码

class STATE:
    SUBMITTED = 'Submitted'
    VERIFIED_BY_DA = 'Verified by DA'
    APPROVED_BY_MS = 'Verified by MS'
    APPROVED_BY_DR = 'Approved by DR'
    APPROVED_BY_SrAO = 'Approved by SAO.'
    APPROVED_BY_R = 'Approved by R'
    AMOUNT_TRANSFERRED = 'Accepted'
    REJECT = 'Rejected'

    def __init__(self):
        pass


STATE_CHOICES = (
    (STATE.SUBMITTED, 'Submitted', 'Medical'),
    (STATE.VERIFIED_BY_DA, 'Verified by DA', 'Medical'),
    (STATE.APPROVED_BY_MS, 'Approved by MD', 'Medical'),
    (STATE.APPROVED_BY_DR, 'Approved by DR', 'Medical'),
    (STATE.APPROVED_BY_SrAO, 'Approved by SAO', 'Medical'),
    (STATE.APPROVED_BY_R, 'Approved by R', 'Medical'),
    (STATE.AMOUNT_TRANSFERRED, 'Amount transferred by AD', 'Medical'),
    (STATE.REJECT, 'Reject', 'Medical'),
)

因此，我在django的models文件夹中单独定义了这两个模型，首先，我只定义了医疗模型，一切都很好。

from django_fsm import FSMField

from state import STATE
from state import STATE_CHOICES

class Medical(BaseModel):

    general_detail = models.ForeignKey(
        GeneralDetail,
        help_text='General Detail'
    )
    state = FSMField(
        blank=True,
        protected=not settings.DEBUG,
        default=STATE.SUBMITTED,
        state_choices=STATE_CHOICES,
    )

    def __str__(self):
        return str(self.general_detail.employee.user.first_name) + ' ' \
               + str(self.general_detail.employee.user.last_name)

    def __unicode__(self):
        return str(self.general_detail.employee.user.first_name) + ' ' \
               + str(self.general_detail.employee.user.last_name)

但是，在添加了下面的模型之后，在使用django-admin保存过渡历史中的字段时会出现django-admin中的错误。

class TransitionHistory(BaseModel):

    state_from = FSMField(
        blank=True,
        protected=not settings.DEBUG,
        default=STATE.SUBMITTED,
        state_choices=STATE_CHOICES,
    )
    state_to = FSMField(
        blank=True,
        protected=not settings.DEBUG,
        default=STATE.SUBMITTED,
        state_choices=STATE_CHOICES,
    )

    def __str__(self):
        return str(self.state_from) + str(self.state_to)

    def __unicode__(self):
        return str(self.state_from) + str(self.state_to)

错误异常类型: DoesNotExist

异常值:不存在医疗匹配查询

C:\Python27\lib\site-packages\django\db\models\query.py in get self.model._meta.object_name的 379 self.model._meta.object_name

只要检查一下您是否进行了迁移，如果是，那么您可能会忘记在admin.py中注册您的模型。
