django启动报：'str' object has no attribute 'decode'

解决： 146行将将decode修改成encode

 

django迁移报index column size too large. the maximum column size is 767 bytes

发生这个错误实在mysql5.6下，我报错是发生在迁移的时候，具体解决请参考我的另外一篇文章：mysql报 index column size too large. the maximum column size is 767 bytes错误解决

 

cWSGI application 'c.wsgi.application' could not be loaded; Error importing

解决： 这个是setting中WSGI_APPLICATION配置和项目中uwsgi文件有误

 

pucharm看不到项目

解决办法： 

1. 第一种方法：点击file->Settings->Project->Project structure 然后把邮编Excluded红色的Excluded Folders目录给删掉就好了～
2. 第二种方法：按project->mark directory as->cancel exclusion 就可以了

django中间件解决跨域问题-No 'Access-Control-Allow-Origin'

现象

解决方法

在app下创建一个middlewares.py文件，写入如下代码:

from django.utils.deprecation import MiddlewareMixin
class MWObj(MiddlewareMixin):
    def process_response(self, request, response):
        response['Access-Control-Allow-Origin'] = "*"
        return response

然后注册

MIDDLEWARE = [
    ... ...
    'app.xx.middlewares.MWObj',
]

 

掉头一去是风吹黑发，回首再来已雪满白发。
