Django IntegrityError：NOT NULL约束失败：

Question

我在尝试提交表单时遇到以下错误？

var url = 'http://omcloud.azurewebsite.net/api/Test';
request.post(url,
            { json: { "Definition": "Test"} },
            function (error, response, body) {
                if (!error && response.statusCode == 200) {
                    console.log(body)
                }
            }
        );

以下是我的File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/django/db/backends/sqlite3/base.py", line 337, in execute return Database.Cursor.execute(self, query, params) IntegrityError: NOT NULL constraint failed: courses_query.course_id 观点：

query_create

以下是我的查询模型：

def query_create(request, course_pk,step_pk):   #what course this quiz belongs to
    text = get_object_or_404(models.Text, course_id=course_pk, pk=step_pk)
    form = forms.QueryForm()  #create blank form

    if request.method == 'POST':
         logging.error('Inside Post.....................................................................')
         form = forms.QueryForm(request.POST)
         if form.is_valid():
             query = form.save(commit=False)  #dont put anything in daabase make model quiz instance
             #query.course = course
             query.text = text
             query.save()

             messages.add_message(request, messages.SUCCESS,
                             "Quiz Added!")
             return HttpResponseRedirect(query.get_absolute_url())
    return render (request,'courses/query_form.html', {'form':form , 'text': text})
