Question

大家好我输入模型时遇到问题，我认为这与循环导入有关。我一直收到错误

cannot import name PurchaseOrder

尽管有这个模型

我的模特

class Project(MAIDEAModel):
    office = models.ForeignKey(
        Office,
        related_name='projects',
        help_text=_('Office which the project is under')
    )
    name = models.CharField(
        _("Name"),
        max_length=50,
        validators=[MinLengthValidator(5), validate_sluggable],
        help_text=_('Name of the project')
    )
    status = models.IntegerField(
        _("Status"),
        choices=STATUS,
        default=STATUS_ACTIVE,
        help_text=_('Activity status of the Project')
    )
    type = models.IntegerField(
        _("Type"),
        choices=PROJECT_TYPES,
        help_text=_('Type of project')

class PurchaseOrder(MAIDEAModel):
    """ This model holds PO numbers for a project
    """
    project = models.ForeignKey(
        Project,
        related_name='purchase_orders',
    )
    number = models.BigIntegerField(
        _('PO Number'),
        validators=[MaxValueValidator(9999999999)]
    )

所以当我导入

时

来自maidea.apps.somalia.models导入Project，PurchaseOrder

我收到错误

ImportError                               Traceback (most recent call last)
<ipython-input-8-6ed2e10f0c28> in <module>()
----> 1 from maidea.apps.somalia.models import PurchaseOrder

ImportError: cannot import name PurchaseOrder

我尝试过使用

from django.apps.import apps
apps.get_model('somalia','PurchaseOrder')

我收到此错误

LookupError: App 'somalia' doesn't have a 'purchaseorder' model.

我正在运行django版

In [28]: django.VERSION
Out[28]: (1, 9, 5, 'final', 0)

我非常需要帮助，我在这里失踪了。感谢

Django：无法导入名称<modelname>
