Question

我正在尝试创建一个允许用户上传文件的应用。我想创建一个处理文件上传的模型。

from django import forms

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

但是当我执行syncdb时遇到以下错误。

Traceback (most recent call last):

    execute_manager(settings)

SyntaxError: invalid syntax

Answer 1

从底部开始阅读你的回溯：

  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， models.py 的第5行存在问题。您错过了一个新行

Answer 2

Soner是对的。此问题很可能是由格式错误引起的。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之后，我几次遇到此错误。如果在复制和粘贴教程或博客中的代码后看到此错误，只需删除粘贴的代码并手动键入代码即可。

最佳，

django代码中的Python“SyntaxError：invalid syntax”
