django - 表单没有错误但 form.is_valid() 不验证 [英] django - form has no errors but form.is_valid() doesn't validate

问题描述

我有一个表单，由于某种原因它不会抛出任何错误(如果用户在文本字段中添加数据)但 form.is_valid() 不会验证.有什么想法吗?

I have a form that for some reason it it doesn't throw any errors (if user adds data in the text field) but form.is_valid() doesn't validate. Any ideas?

forms.py:

class MyForm(forms.Form):
    title = forms.CharField(widget=forms.TextInput(attrs={'class':'titleField')) 

mytemplate.html

mytemplate.html

  <form action="" method="post" name="form">{% csrf_token %}
  {{ form.title.errors }}
  {{ form.title }}
  <input type="submit" name='submit_button' value="Post" />
  </form>

views.py:

      if 'submit_button' in request.POST:
            form = MyForm(request.POST)
            if form.is_valid():
               cd = form.cleaned_data 
               title = cd['title']
               g = MyData(title='title')   
               g.save()

       else:
            form = MyForm() 

推荐答案

从您的模板中，添加以下内容:

From your template, add the following:

{{ form.errors }}
{{ form.non_field_errors }}

您是否发现以上内容有任何错误?
