我们如何在Django中进行通配符搜索。如果我要从数据库中的列表中过滤用户名，怎么可能显示具有这些确切用户名或其中一部分的过滤数据？？

How can we do a wildcard searching in Django. If i am filtering username from a list in database, how is it possible to display the filtered data with those exact usernames or part of it.?

def filter(request): val3='' if request.GET.has_key('choices'): val2=request.GET.get('choices') if request.GET.has_key('textField'): val3=request.GET.get('textField') if request.POST: val2=request.POST.get('choices') val3=request.POST.get('textField') if val2=='Designation': newData = EmployeeDetails.objects.filter(designation=val3) flag=True elif val2=='Name': newData = EmployeeDetails.objects.filter(userName=val3) flag=True elif val2=='EmployeeID': newData = EmployeeDetails.objects.filter(employeeID=val3) flag=True elif val2=='Project': newData = EmployeeDetails.objects.filter(project=val3) flag=True elif val2=='DateOfJoin': newData = EmployeeDetails.objects.filter(dateOfJoin=val3) flag=True else: return HttpResponseRedirect('/employeeList/')

这是我的功能用于过滤。现在使用准确的单词进行过滤。我想显示用户名，即使其中一部分用于过滤也是如此。请帮我解决这个问题，因为我是Django新手

This is my function for filtering. Now its filtering with exact words. I want to display the userNames even if part of it is given for filtering. Please help me to solve this as i am new with Django

推荐答案

请尝试使用不太严格的过滤器，例如__contains：

Try using a less strict filter, like __contains:

elif val2=='Name': newData = EmployeeDetails.objects.filter(userName__contains=val3) flag=True
