Django获取模型日期字段值

Question

class Bla(Case):
def __init__(self, model, field, condition=None, then=None, **lookups):
la = model._meta.get_field(field).__str__

返回

<bound method Field.__str__ of <django.db.models.fields.DateField: date>>

如何获取日期字段的值，特别是年份？

Answer 1

我用这种方法解决了

class Bla(Case):
def __init__(self, model, field, condition=None, then=None, **lookups):
la = model.objects.first()
field_object = model._meta.get_field(field)
field_value = field_object.value_from_object(la)
year = field_value.year
