Question

如标题所述。即使选中，BooleanField也不会返回True。这个让我疯了！

首先，我根据模型的字段ID列表检索复选框。

forms.py

class MyForm(forms.Form):
    def __init__(self, *args, **kwargs):
        super(MyForm, self).__init__(*args, **kwargs)
        fields = Fields.objects.all()
        for field in fields:
            field_name = field.ID
            self.fields[field_name] = forms.BooleanField(required=False, widget=forms.CheckboxInput(attrs={'class':'checkbox-small'}), label=field_name)

即使在DOM中检查过，处理程序也永远不会返回True。

models.py

def myFormHandler(request):
    siteDictionary = getDictionary(request)
    if request.method == 'POST':
        form = MyForm(request.POST, error_class=DivErrorList, auto_id='%s')
        if form.is_valid():
            fields = Fields.objects.all()
            for field in fields:
                if form.cleaned_data[field.ID]:
                    print "Finally returned true!"
    else:
        form = MyForm()
        siteDictionary['form'] = form
    return render_to_response('page.html', siteDictionary, context_instance=RequestContext(request))

有什么想法吗？谢谢你的帮助。

编辑以下是模板

<table cellspacing="0" cellpadding="0" border="0" class="table-all">
    <thead>
        <tr>
            <th><input type="checkbox" name="check" class="checkall checkbox-small" /></th>
            <th>Name</th>
        </tr>
    </thead>
    <tbody>
    {% for field in form %}
        <tr>
            <td>{{ field }}</td>
            <td>{{ field.label }}</td>
        </tr>
    {% endfor %}
    </tbody>
</table>

<div id="pager" class="pager">
<form method="post" action=".">{% csrf_token %}
        <button type="submit" class="green"><span>Submit</span></button>
</form>
</div>

Answer 1

您的字段不在HTML表单元素中，因此不会提交。

Answer 2

field.ID是整数吗？如果是这样，您需要在生成field_name时将其强制转换为字符串。

class MyForm(forms.Form):
    def __init__(self, *args, **kwargs):
        super(MyForm, self).__init__(*args, **kwargs)
        fields = Fields.objects.all()
        for field in fields:
            field_name = str(field.ID)
            self.fields[field_name] = forms.BooleanField(required=False, widget=forms.CheckboxInput(attrs={'class':'checkbox-small'}), label=field_name)

无论是否选中，Django BooleanField都会保持返回False（空）
