有关系的fixture在app-engine-patch中能工作吗？

Question

我有一个具有多个模型的夹具，我正在使用它进行测试。它适用于基本模型，但无法为具有关系的模型创建实体。这是app-engine-patch的一个已知限制，还是我遗漏了什么？我使用JSON作为fixture文件。

我正在使用'manage.py dumpdata --format=json >> file.json‘创建fixture文件。

以下是涉及到的模型：

class BibleBook(db.Model):
    name = db.StringProperty(required=True)
    description = db.TextProperty(required=True)

class Task(db.Model):
    name = db.StringProperty(required=True)
    description = db.TextProperty(required=True)
    energy = db.IntegerProperty(default=1)
    focus = db.IntegerProperty(default=0)
    empathy = db.IntegerProperty(default=0)
    denarii = db.IntegerProperty(default=0)
    talents = db.IntegerProperty(default=0)
    experience = db.IntegerProperty(default=1)
    percent_per_task = db.IntegerProperty(default=5)
    bibleBook = db.ReferenceProperty(BibleBook)
    level = db.StringProperty(required=True, choices=set(["Catachumen", "Laymen", "Elder"]))
    drop_percentage = db.IntegerProperty(default=10)

fixture文件中的json如下所示：

[
{"pk": "ag5sYXctYW5kLWdvc3BlbHIcCxIWbGF3YW5kZ29zcGVsX2JpYmxlYm9vaxgDDA", 
 "model": "lawandgospel.biblebook", 
 "fields": {"name": "Luke", "description": "Description"}},

{"pk": "ag5sYXctYW5kLWdvc3BlbHIXCxIRbGF3YW5kZ29zcGVsX3Rhc2sYBQw",
 "model": "lawandgospel.task",
 "fields": {"empathy": 0, "name": "Study Luke", "level": "Catachumen", "energy": 1,
 "focus": 0, "experience": 1, "drop_percentage": 10, "talents": 0,
 "bibleBook": "ag5sYXctYW5kLWdvc3BlbHIcCxIWbGF3YW5kZ29zcGVsX2JpYmxlYm9vaxgDDA",
 "percent_per_task": 5, "denarii": 0, "description": "The Book of Luke"}}
]

BibleBook模型可以正确加载，但Task不能。我通过执行以下操作来检查：

books = BibleBook.gql('')
self.assertEquals(books.count(), 1)
tasks = Task.gql('')
self.assertEquals(tasks.count(), 1)

第一个测试通过了，但第二个没有通过。

谢谢,

谢谢，塞洛普，你要额外的代码。我决定使用json文件，并通过对pk使用简单的数字来修复问题。以下是为我发布的模型和测试修复问题的JSON：

[
{"pk": "1",
 "model": "lawandgospel.biblebook",
 "fields": {"name": "Luke", "description": "The Gospel According to St. Luke."}},

{"pk": "2",
 "model": "lawandgospel.task",
 "fields": {"empathy": 0, "name": "Study the Gospel of Luke", "level": "Catachumen",
 "energy": 1, "focus": 0, "experience": 1, "drop_percentage": 10, "talents": 0,
 "bibleBook": "1", "percent_per_task": 5, "denarii": 0,
 "description": "The Book of Luke"}}
