所以,目前我这样做,你可以搜索用户,参加了一个偶数,通过一些过滤器是 first_name, last_name, username
当前错误为
要解包的值太多(应为2)
视图中的错误行:
makefilter = "user__"+searchfilter+"__contains="+searchinput
usersearch = TeamMembership.objects.filter(makefilter)
如何通过过滤器成功搜索?
我的观点.py:
def volunteer(request):
## init context
context = {}
## Get filters if somes
searchfilter = request.GET.get('filter', None)
searchinput = request.GET.get('searchinput', None)
## Checks if filter is not none or null or empty
if searchfilter != "" and searchfilter != None and searchinput != "" and searchinput != None:
## Great now check what filter is used
## Now strip the filters for whitespaces
searchfilter.strip()
searchinput.strip()
## This filter is for teams
if searchfilter == "teamname":
teamsearch = Team.objects.all().filter(name__contains=searchinput)
context['teams'] = True
context['search'] = teamsearch
## This filter is for users
elif searchfilter == "first_name" or searchfilter == "last_name" or searchfilter == "username" or searchfilter == "phone":
makefilter = "user__"+searchfilter+"__contains="+searchinput
usersearch = TeamMembership.objects.filter(makefilter)
context['users'] = True
context['search'] = usersearch
return render(request, 'volunteer/hqvolunteer.html', context)
我的模型我试图搜索的用户模型是标准django auth:
class TeamMembership(models.Model):
user = models.ForeignKey(User)
team = models.ForeignKey(Team)
ingroup = models.BooleanField(default=False)
leader = models.BooleanField(default=False)
groupleader = models.BooleanField(default=False)

在这里,您只需要构造一个字符串,也许它的形状类似于python代码,但这并不是您将任意参数名传递给函数的方式。
这里可以使用关键字参数,并构造一个字典,将键(参数的名称)Map到值(应该与该参数对应的值),如:
万一
search_filter
例如'email'
,和searchinput
存在'bar'
,则会导致some_dict
存在{ 'user__email__contains': 'bar' }
,并呼叫:相当于:
如果要筛选多个项,可以构造具有多个键的字典。但是请注意,键(如参数名)不能冲突(使用两次或两次以上相同的命名参数调用函数)。
此外,请注意
User
模型包含(散列)密码和其他敏感数据,您可能希望避免对某些字段进行过滤,因为可以使用此机制从系统中破解数据。
