I am writing django application and stuck with the error

'unicode' object has no attribute 'get'
I saw a lot of questions here but no one matches with mine issue.
我在这里看到了很多问题，但没有一个与我的问题相符。
The issue is with my method in views.py that should return JSON:
问题在于我在 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
My urls.py
我的网址.py
urlpatterns = [
url(r'^get_pattern(?P<product_id>[0-9]+)/$', views.get_pattern, name='get_pattern'),
]
]
I've tried everything. But when you go /get_pattern1 it returns:
我什么都试过了。但是当你去 /get_pattern1 它返回：
Request Method: GET
Request URL: http://xxxxxxx:8000/xxxx/get_pattern1/

return product_data
A Django view must return an HttpResponseobject, not a string.
Django 视图必须返回HttpResponse对象，而不是字符串。
bytes = product_data.encode('utf-8')
return django.http.HttpResponse(bytes, content_type='application/json')
(The clickHymaning middleware is raising an error because it is assuming the return value from the view is an HttpResponse and calling get()on it, but actually it's, erroneously, a unicodestring.)
（点击劫持中间件引发错误，因为它假设视图的返回值是一个 HttpResponse 并调用get()它，但实际上它错误地是一个unicode字符串。）
