Question

我有一个名为Blueprint的模型类：

class Blueprint(models.Model):
    name = models.CharField(max_length=120)
    description = models.TextField()
    workloads = models.CharField(choices=WORKLOAD_CHOICES)

    class Meta:
        ordering = ["name", ]

此模型的子项名为工作负载。

对于django和tastypie都是全新的，我有这个问题：

1）我在哪里执行逻辑，它检索工作负载列表，并在models.py（作为 init 的一部分）或api.py中填充WORKLOAD_CHOICES： def obj_get的一部分？

P.S。这是api.py：

class BlueprintResource(ModelResource):
    def obj_create(self, bundle, request=None, **kwargs):
        return super(BlueprintResource, self).obj_create(bundle, request)

    def obj_update(self, bundle, request=None, **kwargs):

        blueprint = Blueprint.objects.get(id=kwargs.get("pk"))
        blueprint.description = bundle.data.get("description")
        blueprint.name = bundle.data.get("name")
        blueprint.workloads = bundle.data.get("workloads")
        blueprint.save()

        def obj_delete(self, bundle, **kwargs):

            return super(BlueprintResource, self).obj_delete(bundle)

    class Meta:
        queryset = Blueprint.objects.all()
        resource_name = 'blueprint'
        authorization=Authorization()

查看build_bundle()和full_dehydrate()。我还没有对此进行测试，但也许这样的事情会起作用。

from my_app.models import WORKLOAD_CHOICES

class BlueprintResource(ModelResource):

    def full_dehydrate(self, bundle, for_list=False):

         dic = dict([WORKLOAD_CHOICES])
         bundle.data['foo'] = self.build_bundle(data=dic)

         return super(BlueprintResource, self).full_dehydrate(bundle, for_list)
