我正在处理 Django 自定义表单: 我已经调试过 form.is_valid 函数没有运行，即使所有数据都出现在 View 中。
模型.py
choices = (
('yes', 'Yes'),
('no', 'No'),
('not sure', 'Not Sure'),
)
class TaggedArticle(models.Model):
user = models.ForeignKey(User, related_name='tagging')
category_fit = models.CharField(choices=choices, max_length=255)
article = models.ForeignKey(Article, related_name='articles')
relevant_feedback = models.TextField(blank=True)
created_at = models.DateTimeField(default=timezone.now, editable=False)
表单.py
class TagForm(forms.ModelForm):
class Meta:
model = TaggedArticle
fields = ('user', 'category_fit', 'article', 'relevant_feedback')
widgets = {
'category_fit': forms.RadioSelect()
}
views.py
def post(self, request, *args, **kwargs):
if request.method == 'POST':
post_data = request.POST.copy()
post_data.update({'user': request.user.pk})
form = forms.TagForm(post_data)
print('request recieved')
if form.is_valid():
tag = TaggedArticle()
tag.user = request.user
article = Article.objects.all().filter(id=form.cleaned_data['article'])
tag.category_fit = form.cleaned_data['category_fit']
tag.article = article
tag.relevant_feedback = form.cleaned_data['relevant_feedback']
tag.save()
return HttpResponse('Tagged Successfully!', status=200)
更新 我认为这是单选按钮错误: 以下是我如何从我的模板中获取它:
<td><label class="radio-inline"><input type="radio" name="category_fit">Yes</label></td>
<td><label class="radio-inline"><input type="radio" name="category_fit">No</label></td>
<td><label class="radio-inline"><input type="radio" name="category_fit">Not Sure</label>
请帮帮我! 提前致谢!
请您参考如下方法:
试一试:
if form.is_valid():
tag = form.save(commit=False)
tag.user = request.user
tag.save()
else:
# Added else statment
msg = 'Errors: %s' % form.errors.as_text()
return HttpResponse(msg, status=400)
您需要将value 属性添加到您的radio:
<td><label class="radio-inline"><input type="radio" name="category_fit" value="yes">Yes</label></td>
<td><label class="radio-inline"><input type="radio" name="category_fit" value="no">No</label></td>
<td><label class="radio-inline"><input type="radio" name="category_fit" value="not sure">Not Sure</label>
<!-- ^^^^^^^^^^ -->
