Django表单列表中的每个项目

Question

我正在尝试使用django制作一个web应用程序，该程序允许用户选择他们相信谁会在几场比赛中获胜的人。我将比赛作为一个模型，包括主队，客队，身份证等。现在提交时，我希望用户将多行插入到具有用户标识和所选团队的表中。

我已经尝试使用formset，但我无法弄清楚他们如何使用不同的标签。

我现在拥有的形式就是这个。

class PickForm(forms.ModelForm): 
''' 
    A form that allows a user to make a pick on the 
    selected game 
''' 
error_messages = { 
    'no_match': ('Your selections do not match the corresponding options') 
} 

team_picked = forms.CharField(label=('Your choice')) 

class Meta: 
    model = Pick 
    fields = ('team_picked',) 

def __init__(self, *args, **kwargs): 
    self.user_id = kwargs.pop('user_id', None) 
    self.matchweek = kwargs.pop('matchweek', None) 
    super(PickForm, self).__init__(*args, **kwargs) 

def clean_team_picked(self): 
    team_picked = self.cleaned_data['team_picked'] 
    if(team_picked == self.home_team): 
     return team_picked 
    elif(team_picked == self.away_team): 
     return team_picked 
    else: 
     raise forms.ValidationError(
      self.error_messages['no_match'], 
      code='no_match', 
     ) 

def save(self, commit=True): 
    pick = super(PickForm, self).save(commit=False) 
    pick.team_picked = self.cleaned_data['team_picked'] 
    pick.user_id = self.user_id 
    pick.matchweek = self.matchweek 
    if commit: 
     pick.save() 
    return pick 

谢谢！

不能肯定你的意思了“不同的标签”是什么，但它看起来像你想有一个模型表单集：https://docs.djangoproject.com/en/1.11/topics/forms/modelforms/#model-formsets

所以你必须像

from django.forms import modelformset_factory 
from models import PickForm 

PickFormSet = modelformset_factory(Pick, form=PickForm, queryset=Pick.objects.filter())
