我在实现 Django 会话时遇到了一些问题。我有一个员工列表页面，上面有一个过滤器选项。过滤是基于字段和在文本框中输入的文本完成的。过滤的用户显示在filter.html页面中；单击用户名会进入该用户的个人资料页面。现在我想返回显示已过滤用户的上一页（在员工个人资料页面中有一个后退按钮）（filter.html）。我想这可以通过会话来完成。但我不确定我使用会话的方式是否正确。请帮我解决这个问题，因为我是 Django 新手。将在这里发布我的代码：

def filter(request):
    val=request.POST.get('designation')      
    val2=request.POST.get('choices')
    val3=request.POST.get('textField')

    if val2=='Designation':                
        newData = EmployeeDetails.objects.filter(designation=request.POST.get('textField'))  
        request.session['session_textField']="textField"  
        request.session['session_choices']="choices"    
        session_textField = request.session["session_textField"]
        session_choices = request.session["session_choices"]
        print session_textField,session_choices
    elif val2=='Name':
        newData = EmployeeDetails.objects.filter(userName=request.POST.get('textField'))
        request.session['session_textField']="textField"  
        request.session['session_choices']="choices"      
        session_textField = request.session["session_textField"]
        session_choices = request.session["session_choices"]
        print session_textField,session_choices        
    elif val2=='EmployeeID':
        newData = EmployeeDetails.objects.filter(employeeID=request.POST.get('textField'))        
        request.session['session_textField']="textField"  
        request.session['session_choices']="choices"      
        session_textField = request.session["session_textField"]
        session_choices = request.session["session_choices"]
        print session_textField,session_choices  
    elif val2=='Project':
        newData = EmployeeDetails.objects.filter(project=request.POST.get('textField'))     
        request.session['session_textField']="textField"  
        request.session['session_choices']="choices"      
        session_textField = request.session["session_textField"]
        session_choices = request.session["session_choices"]
        print session_textField,session_choices     
    elif val2=='DateOfJoin':
        newData = EmployeeDetails.objects.filter(dateOfJoin=request.POST.get('textField'))       
        request.session['session_textField']="textField"  
        request.session['session_choices']="choices"      
        session_textField = request.session["session_textField"]
        session_choices = request.session["session_choices"]
        print session_textField,session_choices   
    else:
        return render_to_response('filter.html') 

    return render_to_response('filter.html',{'newData':newData,'val2':val2})

如果我提供的代码有很多错误，请帮助我更正它。

完全不清楚您要做什么。但请注意：

request.session['session_textField']="textField"  
request.session['session_choices']="choices"

这两行在每个块中都是相同的，只需将两个会话变量设置为字符串“textField”和“choices”。我不认为这是你想要做的，尽管正如我上面所说的，我不知道你到底想要做什么。然而，这似乎是一个基本的编程问题，与 Django 会话无关。
