ValueError:字段"id"应为数字，但已得到“正在处理" [英] ValueError: Field 'id' expected a number but got 'Processing'

问题描述

我要在DigitalOcean上部署django应用程序.一切顺利，除了以下错误，我的问题是:在哪里可以找到此错误的根源，实际上是在哪个文件中?

I'm going to deploy my django application on DigitalOcean. Everything gone well, except following error, and my question is: where can I find source of this error, actually in which file ?

Operations to perform:
  Apply all migrations: admin, auth, ccapp, contenttypes, sessions
Running migrations:
  Applying ccapp.0009_auto_20191207_2148...Traceback (most recent call last):
  File "/home/progbash/ccproject/env/lib/python3.6/site-packages/django/db/models/fields/__init__.py", line 1768, in get_prep_value
    return int(value)

ValueError: invalid literal for int() with base 10: 'Processing'

The above exception was the direct cause of the following exception:

推荐答案

问题出在迁移文件中.我只是打开并将默认值从字符串类型更改为整数.

The problem was in migration files. I just opened and changed default value from string type to integer.
