python - 列表中每个项目的 Django 表单

Question

我正在尝试使用 django 制作一个网络应用程序，允许用户选择他们认为在几场比赛中获胜的人。我将比赛作为模型，其中包含主队、客队、ID 等。现在，在提交时，我希望用户将多行插入到包含用户 ID 和他们选择的团队的表中。

我尝试过使用表单集，但我无法弄清楚它们如何与不同的标签一起使用。

我目前的表格是这样的。

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!

不确定您对“不同标签”的意思，但看起来您想要一个模型表单集:https://docs.djangoproject.com/en/1.11/topics/forms/modelforms/#model-formsets

所以你会有类似的东西

from django.forms import modelformset_factory
from models import PickForm

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