Question

我有以下表格：

# coding=utf-8

class SelectTwoTeams(BootstrapForm):

    def __init__(self, *args, **kwargs):
        user = kwargs.pop('user', None)
        self.currentSelectedTeam1 = kwargs.pop('currentSelectedTeam1', None)
        self.currentSelectedTeam2 = kwargs.pop('currentSelectedTeam2', None)
        self.currentfixturematchday = kwargs.pop('currentfixturematchday', None)
        self.currentCampaignNo = kwargs.pop('currentCampaignNo', None)
        super(SelectTwoTeams, self).__init__(*args, **kwargs)

        cantSelectTeams = UserSelection.objects.select_related().filter(~Q(fixtureid__fixturematchday=self.currentfixturematchday),campaignno=self.currentCampaignNo)

        if not cantSelectTeams:
            queryset = StraightredTeam.objects.filter(currentteam = 1)
        else:
            queryset = StraightredTeam.objects.filter(currentteam = 1).exclude(teamid__in=cantSelectTeams.values_list('teamselectionid', flat=True))


        self.fields['team1'].queryset = queryset
        self.fields['team2'].queryset = queryset
        self.fields['team1'].initial = self.currentSelectedTeam1
        self.fields['team2'].initial = self.currentSelectedTeam2

    team1 = forms.ModelChoiceField(queryset=StraightredTeam.objects.none(), empty_label=None,
                               widget=forms.Select(attrs={"class":"select-format",'onchange': 'this.form.submit();'}))
    team2 = forms.ModelChoiceField(queryset=StraightredTeam.objects.none(), empty_label=None,
                               widget=forms.Select(attrs={"class":"select-format",'onchange': 'this.form.submit();'}))

    def clean(self):
        cleaned_data = self.cleaned_data # individual field's clean methods have already been called
        team1 = cleaned_data.get("team1")
        team2 = cleaned_data.get("team2")
        if team1 == team2:
            raise forms.ValidationError("You picked the same team!")

        return cleaned_data

如果我在我的HTML文件中使用以下内容并选择相同的两个团队，它会正确地说＃34;你选择了同一个团队！＆＃34;：

    <form action="" method="post">
        {% csrf_token %}
        {{ form }}
    </form>

但是，如果我使用以下内容：

    <form action="" method="post">
        {% csrf_token %}
        {{ form.team1 }}{{ form.team2 }}
    </form>

我没有得到反馈。当我选择相同的两支球队时，什么也没发生。任何关于为什么分离字段的想法都会使它停止工作？

非常感谢，艾伦。

这些之间的区别不是＆＃34;分隔字段＆＃34;。您已经从完整的表单表示（包括表单标签，布局，最重要的是错误）切换到仅显示两个输入字段本身。

当然，这很好，因为大多数情况下你会想要它给你的额外布局控制，但是你需要记住放入基本{{1}的所有其他东西。版本确实。

{{ form }}
