Python 使用Tastypie覆盖模型字段
在我的一个视图中，我定义了一个mixin，根据用户的会话详细信息动态设置许多模型（包括客户机模型）的Python 使用Tastypie覆盖模型字段,python,django,tastypie,Python,Django,Tastypie,在我的一个视图中，我定义了一个mixin，根据用户的会话详细信息动态设置许多模型（包括客户机模型）的tech和operator字段，这样用户就不需要手动填写它们。该混合物如下所示： class GetTechMixin(object): """ View mixin that when the form is saved, sets the site_user and operator. """ def form_valid(self, form):
techoperatorclass GetTechMixin(object):
"""
View mixin that when the form is saved, sets the
site_user and operator.
"""
def form_valid(self, form):
# Get user
user = self.request.user
# Get tech for this user
site_user = SiteUser.objects.get(user=user)
# Override the tech and operator fields
form.instance.tech = site_user
form.instance.operator = site_user.operator
# Save the object
self.object = form.save()
# Return success URL
return HttpResponseRedirect(self.get_success_url())
def obj_create(self, bundle, **kwargs):
# Get tech for this user
site_user = SiteUser.objects.get(user=bundle.request.user)
bundle.obj = self._meta.object_class()
for key, value in kwargs.items():
setattr(bundle.obj, key, value)
# Override the tech and operator fields
setattr(bundle.obj, 'tech', site_user)
setattr(bundle.obj, 'operator', site_user.operator)
self.authorized_create_detail(self.get_object_list(bundle.request), bundle)
bundle = self.full_hydrate(bundle)
return self.save(bundle);
class ClientResource(AbstractModelResource):
class Meta(AbstractModelResource.Meta):
queryset = Client.objects.all()
resource_name = 'client'
def obj_create(self, bundle, **kwargs):
# Get tech for this user
site_user = SiteUser.objects.get(user=bundle.request.user)
# Override the tech and operator fields
bundle.obj.tech = site_user
bundle.obj.operator = site_user.operator
super(ClientResource, self).obj_create(bundle, **kwargs)
bundleobj_是否创建了覆盖这些值的正确位置？如果是这样的话，谁能指出我哪里做错了。如果没有，我应该去哪里寻找呢？如果有人发现了这个，我会找到一个解决方案。最简单的方法就是用一个新方法覆盖obj_create方法，如下所示：
class GetTechMixin(object):
"""
View mixin that when the form is saved, sets the
site_user and operator.
"""
def form_valid(self, form):
# Get user
user = self.request.user
# Get tech for this user
site_user = SiteUser.objects.get(user=user)
# Override the tech and operator fields
form.instance.tech = site_user
form.instance.operator = site_user.operator
# Save the object
self.object = form.save()
# Return success URL
return HttpResponseRedirect(self.get_success_url())
def obj_create(self, bundle, **kwargs):
# Get tech for this user
site_user = SiteUser.objects.get(user=bundle.request.user)
bundle.obj = self._meta.object_class()
for key, value in kwargs.items():
setattr(bundle.obj, key, value)
# Override the tech and operator fields
setattr(bundle.obj, 'tech', site_user)
setattr(bundle.obj, 'operator', site_user.operator)
self.authorized_create_detail(self.get_object_list(bundle.request), bundle)
bundle = self.full_hydrate(bundle)
return self.save(bundle);

site\u user.operator的值
