Question

所以我的模特中有这个：

class narative(models.Model):
    voice = models.FileField(upload_to='uploads/%Y/%m/%d',blank = True, null=True)

    def     filename(self):
        return os.path.basename(self.voice.name)

    def clean(self):
        return os.path.basename(self.voice.name)

    def __unicode__(self):
        return self.filename()


class geolocations(models.Model):
    name = models.CharField(max_length=255)
    parent = models.ForeignKey('self', blank=True,null=True)
    sort = models.IntegerField(default=0, blank=True,null=True)
    description = HTMLField()
    locations = models.ManyToManyField('locgeo')
    excerpt = models.CharField(max_length=4096)
    icon = models.CharField(max_length=255, blank = True, null=True)
    tags = models.CharField(max_length=255, blank = True, null=True)
    categories = models.ManyToManyField('categories',blank = True, null=True)
    photos = models.ManyToManyField('Photo', blank = True, null=True)
    narations = models.ManyToManyField('narative', blank = True, null=True)

然后在我的api.py

中

class NarRes(ModelResource):
    class Meta:
        queryset = narative.objects.all()
        resource_name = 'nar'

class EntryResource(ModelResource):
    locations = fields.ToManyField('self', filter_locations_per_bundle, full=True, null=True)
    locgeo = fields.ToManyField('myapp.api.LocGeoRes', 'locations', full=True, null=True)
    photos = fields.ToManyField('myapp.api.photoResource','photos', full=True, null=True)
    narative = fields.ToManyField('myapp.api.NarRes','narative', full=True, null=True)

    class Meta:
        queryset = geolocations.objects.all()
        resource_name = 'Locations'
        fields = ['parent','narative','id','name','description','excerpt','lgeo','icon','tags','categories','photos','locations']

问题是，json输出将narative列为空数组：

...
locations: [ ],
locgeo: [
{
id: 1,
latitude: "33",
longitude: "22",
name: "Location",
radius: 140,
resource_uri: "/api/v1/lgeo/1/"
}
],
name: "Location",
narative: [ ],
photos: [
{
id: 6,
name: "Location",
photo: "/media/uploads/2014/04/18/IMG_1643_result.JPG",
resource_uri: "/api/v1/photos/6/"
},
...

当我知道该记录有一个条目时（我可以在列出比较资源时看到它）。

我做错了什么？

Answer 1

如模型中所示，外键的名称是“narations”。在我的资源中，我将其称为“narative”。

修改后的行应为：

narative = fields.ToManyField('myapp.api.NarRes','narations', full=True, null=True)

修正了它。
