我有两套灯具,Person.json和Movies.json。 Person夹具基本上具有以下格式:
{
"pk": 1,
"model": "data.Person",
"fields": {
"full": "Anna-Varney",
"num": "I",
"short": "Anna-Varney"
}
},
我首先加载它,没关系没问题。我的movie.json看起来像这样:
{
"pk": 1,
"model": "data.Film",
"fields": {
"date": "2005-08-01",
"rating": 8.3,
"actors": [
[
"Anna-Varney"
]
],
"name": "Like a Corpse Standing in Desperation (2005) (V)"
}
},
加载电影夹具会给我这个错误:
DeserializationError: Problem installing fixture 'data/fixtures/movies.json': Person matching query does not exist.
我的模特是:
class PersonManager(models.Manager):
def get_by_natural_key(self, full):
return self.get(full=full)
class Person(models.Model):
objects = PersonManager()
full = models.CharField(max_length=100,unique = True)
short = models.CharField(max_length=100)
num = models.CharField(max_length=5)
def natural_key(self):
return (self.full,)
def __unicode__(self):
return self.full
class Film(models.Model):
name = models.TextField()
date = models.DateField()
rating = models.DecimalField(max_digits=3 , decimal_places=1)
actors = models.ManyToManyField('Person')
def __unicode__(self):
return self.name
我在过去加载了类似的模型和装置,但我正在尝试重构我的一些代码,所以现在它不起作用。我做的一个值得注意的变化是我是PostgreSQL而不是MySQL,而且我在virtualenv中运行一切。 有没有办法确定错误发生在灯具中的哪个位置?
