因此,目前,您可以通过first_name, last_name, username
当前错误
要解包的值太多(预期为2)
视图中的错误线:
makefilter = "user__"+searchfilter+"__contains="+searchinput
usersearch = TeamMembership.objects.filter(makefilter)
如何通过过滤器成功搜索?
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)
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,您仅构造一个 string ,也许它的形状类似于Python代码,但这不是将任意参数 names 传递给函数的方式。>
您可以在这里使用关键字参数,并构建一个字典,该字典将 key (参数名称)映射为 value (应与该参数对应的值),例如:
some_dict = { "user__"+searchfilter+"__contains": searchinput}
usersearch = TeamMembership.objects.filter(**some_dict)
如果search_filter
是'email'
,而searchinput
是'bar'
,那么这将导致some_dict
是{ 'user__email__contains': 'bar' }
,并致电:
TeamMembership.objects.filter(**{ 'user__email__contains': 'bar' })
等效于:
TeamMembership.objects.filter(user__email__contains='bar')
如果要过滤多个项目,则可以构造具有多个键的字典。但是请注意,键(如参数名称)不能发生冲突(调用具有两次或多次相同的 named 参数的函数)。
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来破解数据退出系统。
