Python”;SyntaxError:无效语法“;在django代码中

Question

我正在尝试创建一个允许用户上传文件的应用程序。我想创建一个模型来处理文件上传。

from django import forms
class UploadFileForm(forms.Form):
    title = forms.CharField(max_length=50)
    file  = forms.FileField()

但是，当我同步数据库时，我会得到以下错误。

Traceback (most recent call last):

SyntaxError: invalid syntax

Answer 1

开始从底部读取回溯：

  File "/home/roy/projects/qsourcing/qsl/models.py", line 5
    title = forms.CharField(max_length=50)                                        file  = forms.FileField()   
                                                                                     ^
SyntaxError: invalid syntax

在这种情况下，模型的第5行中存在问题。py。您缺少一个新行

Answer 2

Soner是正确的。此问题很可能是由不正确的格式引起的。在我从教程或博客中复制代码，然后将其直接粘贴到我的项目中后，我曾多次遇到此错误。如果您在从教程或博客复制并粘贴代码后看到此错误，只需删除粘贴的代码，然后手动键入代码即可。

最佳，
