Django Tastypie,将元素添加到多对多关系中
我正在构建一个django-tastypie api,在Django Tastypie,将元素添加到多对多关系中,django,rest,tastypie,Django,Rest,Tastypie,我正在构建一个django-tastypie api,在manytomy关系中添加元素时遇到问题 例如, models.py class Picture(models.db): """ A picture of people""" people = models.ManyToManyField(Person, related_name='pictures', help_text="The people in this picture", ) class
manytomy
关系中添加元素时遇到问题
例如,
models.py
class Picture(models.db):
""" A picture of people"""
people = models.ManyToManyField(Person, related_name='pictures',
help_text="The people in this picture",
)
class Person(models.db):
""" A model to represet a person """
name = models.CharField(max_length=200,
help_text="The name of this person",
)
资源:
class PictureResource(ModelResource):
""" API Resource for the Picture model """
people = fields.ToManyField(PersonResource, 'people', null=True,
related_name="pictures", help_text="The people in this picture",
)
class PersonResource(ModelResource):
""" API Resource for the Person model """
pictures = fields.ToManyField(PictureResource, 'pictures', null=True,
related_name="people", help_text="The pictures were this person appears",
)
我的问题是,我希望在图片资源中有一个add_person
端点。
如果使用PUT
,则需要指定图片中的所有数据
如果我使用PATCH
,我仍然需要指定图片中的所有人。
当然,我可以简单地生成/api/picture/:id/add_people
URL,在那里我可以处理我的问题。问题是它感觉不干净
另一个解决方案是生成/api/picture/:id/people
端点,在那里我可以做GET
,POST
,PUT
,就像这是一个新资源一样,但我不知道如何实现这一点,在这个资源下创建新的人员似乎很奇怪
有什么想法吗?我通过重写API资源的save_m2m函数实现了这一点。下面是一个使用您的模型的示例
def save_m2m(self, bundle):
for field_name, field_object in self.fields.items():
if not getattr(field_object, 'is_m2m', False):
continue
if not field_object.attribute:
continue
if field_object.readonly:
continue
# Get the manager.
related_mngr = getattr(bundle.obj, field_object.attribute)
# This is code commented out from the original function
# that would clear out the existing related "Person" objects
#if hasattr(related_mngr, 'clear'):
# Clear it out, just to be safe.
#related_mngr.clear()
related_objs = []
for related_bundle in bundle.data[field_name]:
# See if this person already exists in the database
try:
person = Person.objects.get(name=related_bundle.obj.name)
# If it doesn't exist, then save and use the object TastyPie
# has already prepared for creation
except Person.DoesNotExist:
person = related_bundle.obj
person.save()
related_objs.append(person)
related_mngr.add(*related_objs)
我问了同样的问题抱歉@seb我搜索了我的问题,但没有找到你的问题。如果您愿意,我可以删除我的问题,但请更改您的名称,因为“如何通过tasytpie API将产品放入购物车”太难了specific@seb-你的问题还没有解决,我看你还没有接受答案!
