Root Cause

Returning an HttpResponse instance but accidentally calling it as a function in the view.

generic

中文

返回HttpResponse实例但意外地将其作为函数调用。

Workarounds

  1. 95% success Return instance without extra parentheses 
    return HttpResponse('Hello')
  2. 90% success Use render shortcut 
    return render(request, 'template.html', context)

Dead Ends

Common approaches that don't work:

  1. Using parentheses after HttpResponse 90% fail

    HttpResponse() returns object, but extra () tries to call it again.

  2. Misunderstanding function vs class 70% fail

    View should return instance, not call it.
