python属性错误怎么改-凯发k8官方网

我正在做一个遗留的django项目，其中有一个类定义如下from django.http import httpresponse

class response(httpresponse):

def __init__(self, template='', calling_context='' status=none):

self.template = template

self.calling_context = calling_context

httpresponse.__init__(self, get_template(template).render(calling_context), status)

这个类在视图中使用如下def some_view(request):

#do some stuff

return response('some_template.html', requestcontext(request, {'some keys': 'some values'}))

这个类的创建主要是为了在单元测试中使用它来执行断言，也就是说，它们不是使用django.test.client来测试视图，而是创建一个模拟请求，并将其传递给测试中的视图(将视图称为可调用的)，如下所示def test_for_some_view(self):

mock_request = create_a_mock_request()

#call the view, as a function

response = some_view(mock_request) #returns an instance of the response class above

self.assertequals('some_template.html', response.template)

self.assertequals({}, response.context)

问题是，在测试套件(相当大的测试套件)的中途，一些测试在执行return response('some_template.html', requestcontext(request, {'some keys': 'some values'}))

堆栈跟踪是self.template = template

attributeerror: can't set attribute

整个堆栈跟踪看起来像======================================================================

error: test_should_list_all_users_for_that_specific_sales_office

----------------------------------------------------------------------

traceback (most recent call last):

实际的失败测试是def test_should_list_all_users_for_that_specific_sales_office(self):

user_company = companyfactory.create()

request = self.mock_request(user_company)

#some other stuff

#calling the view

response = show(request, sales_office_id=sales_office.id)

self.assertin(user, response.calling_context["sales_office_users"])

self.assertnotin(user2, response.calling_context["sales_office_users"])

显示视图的代码def show(request, sales_office_id):

user = request.user

sales_office = []

sales_office_users = []

associated_market_names = []

try:

sales_office = salesoffice.objects.get(id=sales_office_id)

sales_office_users = user.objects.filter(userprofile__sales_office=sales_office)

associated_market_names = market.objects.filter(id__in= (sales_office.associated_markets.all())).values_list("name", flat=true)

if user.groups.all()[0].name == userprofile.company_ao:

associated_market_names = [market.name for market in sales_office.get_sales_office_user_specific_markets(user)]

except:

pass

return response("sales_office/show.html", requestcontext(request, {'keys': 'values'}))
