Python django 代码中的“SyntaxError：无效语法”

Question

I am trying to create an app that will enable a user to upload a file. I want to create a model that will handle the file upload.

from django import forms

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

But upon doing this when I syncdb I get the following error.

Traceback (most recent call last):

SyntaxError: invalid syntax

Answer 1

Start reading your backtrace from the bottom:

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

In this case there is a problem in line 5 of models.py . You are missing a new line

Soner is correct. This issues is most likely caused by incorrect formatting. I have come across this error a few times after I copied code from a tutorial or blog and then pasted it directly into my project. If you see this error after copy and pasting code from a tutorial or blog, simply delete the pasted code and manually type out the code instead.

Best,
