使用表格发帖时出现字符错误

Question

有没有人遇到像这样的错误？当我试着用表单进行登录，并从MySQL检查数据，我得到了错误：

Request Method: POST 
Request URL: http://tesmyapp.loc/post/login/ 
Django Version: 1.9.7 
Exception Type: OperationalError 
Exception Value:  
near "����������": **syntax error** 
Exception Location: /myapp/env/lib/python2.7/site-packages/django/db/backends/sqlite3/operations.py in _quote_params_for_last_executed_query, line 129 
Python Executable: /myapp/env/bin/uwsgi 

我不知道这是从MySQL错误，因为当我试图张贴不检查数据库，错误仍然出现在views.py

@csrf_protect 
def post_login(request): 
    if request.method == 'POST': 
     username = request.POST.get("username", "") 
     password = request.POST.get("password", "") 
     mylogin = check_login(username, password) 
     if mylogin > 0: 
      occur = "success" 
      request.session['member'] = username 
      return HttpResponseRedirect("/home") 

如果有人面对这个错误，请分享解决方案

功能。感谢
