'unicode'对象没有属性'get'

Question

我正在写django应用程序并坚持错误

'unicode' object has no attribute 'get'

我在这看到很多问题,但没有人跟我的问题相符.

问题是我在views.py中的方法应该返回JSON:

def get_pattern(request, product_id):
    """
    Get JSON for needed pattern
    """
    data = Patterns.objects.get(related_module=product_id)
    product_data = serializers.serialize("json", [data, ])
    return product_data

我的urls.py

urlpatterns = [
url(r'^get_pattern(?P<product_id>[0-9]+)/$', views.get_pattern, name='get_pattern'),

]

我已经尝试了一切.但当你去/ get_pattern1它返回:

Request Method: GET
Request URL:    http://xxxxxxx:8000/xxxx/get_pattern1/
Django Version: 1.8.3
Exception Type: AttributeError
Exception Value:    
'unicode' object has no attribute 'get'
Exception Location: /home/xxxx/local/lib/python2.7/site-    packages/django/middleware/clickjacking.py in process_response, line 31

return product_data

Django视图必须返回一个HttpResponse对象,而不是一个字符串.

bytes = product_data.encode('utf-8')
return django.http.HttpResponse(bytes, content_type='application/json')

(点击劫持中间件引发了一个错误,因为它假设视图中的返回值是一个HttpResponse并调用get()它,但实际上它是错误的unicode字符串.)
