NameError-未定义全局名称

Question

我正在尝试从html表单中读取一些数据并将其插入数据库。 这样做使我陷入了此错误“ / createEmployee /处的NameError：未定义全局名称'get_post_param'”； 我将在此处粘贴我的代码。 有人可以帮我解决这个问题吗？
观点

def createEmployee(request):
    if request.method == "POST":
        userName = get_post_param(request,"userName")
        designation = get_post_param(request,"designation")
        employeeID = get_post_param(request,"employeeID")
        contactNumber = get_post_param(request,"contactNumber")
        project = get_post_param(request,"project")
        dateOfJoin = get_post_param(request,"dateOfJoin")
        EmployeeDetails(userName=userName,designation=designation,employeeID=employeeID,contactNumber=contactNumber,project=project,dateOfJoin=dateOfJoin).save()
        return render_to_response('createEmployee.html')
    else:
        return render_to_response('createEmployee.html')

Answer 1

这是一个非常简单的问题。 您尚未定义get_post_param 。
您从哪里得到这个get_post_param想法？

只需定义一个名为get_post_param的函数即可对其进行修复。

这是python shell会话

>>> get_post_param(request, 'userName')
NameError: not defined

>>> def get_post_param(request, param):
...    return request.POST.get(param) 
       # or scrap the idea of a function to do a one liner op anyways

>>> get_post_param(request, 'userName'):
'my_username'
