Django Model Boolean Field最初需要取消选中。 initial = False required = False不起作用

Forms.py

class CheckPostedForm(forms.ModelForm):
        posted = forms.BooleanField(required=False, initial=False)

Views.py

       postform = CheckPostedForm(request.POST, instance=author)
       if postform.is_valid():
            postform.save()
       else:
            print 'Cannot save post form.'

Models.py

posted = models.CharField(max_length=2, blank=True, null=True)
class Meta:
    model = TmpPlInvoice
    exclude = ['net_amt', 'post_date', 'address', 'particulars', 'pos_code', 'acct', 'cust', 'voucher_id', 'voucher_date', 'post_date']
    labels = {
        'posted': 'Posted',
    }

我想要一个最初未选中的复选框,并根据来自DB的值检查/取消选中它。无论我做什么,表格总是出现在检查="检查"。

print postform给出了这个,

<tr><th><label for="id_posted">Posted:</label></th><td><input checked="checked" id="id_posted" name="posted" type="checkbox" value="n" required /></td></tr>

我已经搜索了很多地方,文档说它应该是最初的假要求=如果我们想要应用条件,则为假。

详细 Views.py

def master_detail_posted(request):
    if request.method == 'GET':
        author = TmpPlInvoice.objects.get(id=1)
        postform = CheckPostedForm(instance=author)
        return render(request,'main.html' ,{'postform': postform})
    if request.method == 'POST':
        author = TmpPlInvoice.objects.get(id=1)
        postform = CheckPostedForm(request.POST, instance=author)
        print postform
        if postform.is_valid():
            logger.info('saving post form %s', postform.cleaned_data)
            postform.save()
        else:
            logger.info('post form is not valid %s %s', postform.errors, request.POST)
        return render(request,'main.html' ,{'postform': postform})

模板

<div> {{ postform }} </div>

您已对模板中的字段进行了硬编码。显然,Django无法更改您明确编写的HTML标记。

您需要在模板中使用Django标记:

<td>{{ form.posted }}</td>
