Question

我正在执行django project 2.1.4，并得到以下错误，我进行了搜索，似乎我一个一个地修复了错误，但是我设法解决了一些问题。但是这些我都能找到任何线索。

runserver或迁移后出错。

    (myenv) C:\Users\Users\Desktop\blog_project\mysite>python manage.py runserver

在这里，我只是单独添加。

  File "C:\Users\Users\Desktop\blog_project\mysite\mysite\urls.py", line 22, in <module>
    path('', include('blog.urls')),

  '
     path('', include('blog.urls')),
 '



   File "C:\Users\Users\Desktop\blog_project\mysite\blog\urls.py", line 2, in <module>
    from .import views

    '
    from .import views
    '



 File "C:\Users\Users\Desktop\blog_project\mysite\blog\views.py", line 4, in <module>
    from blog.forms import PostForm,CommentForm

'
from blog.forms import PostForm,CommentForm
'



File "C:\Users\Users\Desktop\blog_project\mysite\blog\forms.py", line 15, in <module>
    class CommentForm(forms.ModelForm):

    '
    class CommentForm(forms.ModelForm):

    '

如何解决此错误？

更新：下面的评论表格

class CommentForm(forms.ModelForm): 
    class Meta: 
        model = Comment 
        fileds = ('author','text',) 
        widgets = { 
            'author':forms.TextInput(attrs={'class':'textinputclass'}), 
            'text':forms.Textarea(attrs={'class':'editable medium-editor-textarea'}) 
        }

Answer 1

从您的CommentForm可以看出，您将fields拼写为fileds。更正该错误以解决该问题：

class CommentForm(forms.ModelForm): 
    class Meta: 
        model = Comment 
        fields = ('author','text',)  # Use correct spelling
        widgets = { 
            'author':forms.TextInput(attrs={'class':'textinputclass'}), 
            'text':forms.Textarea(attrs={'class':'editable medium-editor-textarea'}) 
        }

Answer 2

您需要在模型表单中添加“字段”或“排除”属性。

# example model:
class Comments(models.Model):
    first_name = models.CharField(max_length=30)
    last_name = models.CharField(max_length=30)
    comment = models.TextField()
# forms:
class CommentForm(forms.ModelForm):
    class Meta(object):
        model = Comments
        exclude = ['first_name', ] 
        # or:
        fields = ['comments', ]

Django == 2.1.4-博客
