Tastypie: Retrieve Related Resource from Model Object
Let's say I have a resource similar to User. One user can have multiple Logins. I have a resource for each type of login.
class UserLoginResource(ModelResource):
class Meta:
resource_name = 'userlogin'
list_allowed_methods = ['get', 'post']
class UserResource(ModelResource):
class Meta:
resource_name = 'user'
list_allowed_methods = ['get', 'post']
How can I retrieve a User using the LoginResource's Get method? For example, to get User where logins = ['good','super'] (note that good and super are LoginResource objects)?
A:
You don't need to override the list method for that. You can use the foreign key relationship defined on your LoginResource model to access the related object.
class UserLoginResource(ModelResource):
class Meta:
resource_name = 'userlogin'
list_allowed_methods = ['get', 'post']
class UserResource(ModelResource):
class Meta:
resource_name = 'user'
list_allowed_methods = ['get', 'post']
class LoginResource(ModelResource):
user = fields.ToManyField(
User, related_name='login')
class Meta:
resource_name = 'login'
list_allowed_methods = ['get', 'post'] ac619d1d87
