Question

views.py：

class AddTeamView(View):
    template_name = 'add_team.html'

    def get (self, request):
        form = TeamForm()
        context = {'form': form}
        return render(request, 'add_team.html', context)

    def post(self, request):
        form = TeamForm(request.POST)
        if form.is_valid():
            team = Team()
            team.name = form.cleaned_data('name')
            team.details = form.cleaned_data('detials')
            context = {'form': form, 'team.name':team.name,'team.details':team.details}

        return render(request, self.template_name, context)

add_team.html：

    {% extends 'base.html' %}
{% block title %}
add team
{% endblock %}

{% block content %}
<form action="/add_team/" method="post">
    {% csrf_token %}
    {{ form }}
    <input type="submit" value="Submit">
</form>
{% endblock %}

forms.py：

from django import forms


class TeamForm(forms.Form):
    name = forms.CharField(label='name of team')
    details = forms.CharField(label='details of team')

当我进入浏览器时，它显示为：

/ add_team /'dict'对象中的

form.cleaned_data是一个字典，因此您可以通过下标或使用.get(..)方法来获得元素（如果缺少键，则返回None或默认值），所以你应该重写：

team.name = form.cleaned_data('name')
team.details = form.cleaned_data('detials')

收件人：

team.name = form.cleaned_data['name']
team.details = form.cleaned_data['details']  # typo: detials -> details

话虽如此，最好制作一个ModelForm：

class TeamForm(forms.ModelForm):
    name = forms.CharField(label='name of team')
    details = forms.CharField(label='details of team')

然后视图如下：

class AddTeamView(View):
    template_name = 'add_team.html'

    def get (self, request):
        form = TeamForm()
        context = {'form': form}
        return render(request, 'add_team.html', context)

    def post(self, request):
        form = TeamForm(request.POST)
        if form.is_valid():
            team = form.save()
            context = {'form': form, 'name':team.name,'details':team.details}

        return render(request, self.template_name, context)

您还应该考虑使用CreateView而不是简单的视图，并在post(..)成功完成后进行重定向，因为在POST的情况下进行渲染会在用户刷新时导致错误页面（有关POST-REDIRECT-GET模式的信息，请参见this Wikipedia article。

表格中的数据清除后，需要获取新数据，该数据是从另一页发布的。

重写：

SELECT DISTINCT IdLocContr
          FROM Contraventii c INNER JOIN Soferi s
            ON c.IdSofer=s.IdSofer INNER JOIN Localitati l
                                           ON s.IdLocSofer=l.IdLoc
         WHERE s.NumeSofer = 'Maneta Gheorghe'
           AND l.DenLoc = 'Pocreaca'
           AND l.Jud = 'IS'
           AND rownum<=1
      GROUP BY IdLocContr

收件人：

team.name = form.cleaned_data('name')
team.details = form.cleaned_data('detials')

希望此帮助！
