【未解决】Django中如何自定义返回分页数据
期间，想要获取：
/conf/development/settings.py
# django-restframework and jwt settings
REST_FRAMEWORK = {
...
# 'DEFAULT_PAGINATION_CLASS': 'apps.core.pagination.StandardResultsSetPagination',
'DEFAULT_PAGINATION_CLASS': 'apps.core.pagination.CustomPagination',
'PAGE_SIZE': 20,
}中的PAGE_SIZE
用：
from django.conf import settings
def list(self, request, *args, **kwargs):
logger.info("ScriptViewSet list: request=%s", request)
logger.info("settings=%s", settings)
logger.info("settings.REST_FRAMEWORK.PAGE_SIZE=%s", settings.REST_FRAMEWORK.PAGE_SIZE)结果：
INFO|20180810 21:21:32|views:list:105|settings=<Settings "conf.development.settings">
File "/Users/crifan/dev/dev_root/company/xxx/projects/xxx/server/xxx/apps/script/views.py", line 106, in list
logger.info("settings.REST_FRAMEWORK.PAGE_SIZE=%s", settings.REST_FRAMEWORK.PAGE_SIZE)
AttributeError: 'dict' object has no attribute 'PAGE_SIZE'现在想要获取Django的当前（development）中的配置
django app settings
django get current settings
好像是引用的写法搞错了，所以提示：
AttributeError: ‘dict’ object has no attribute ‘PAGE_SIZE’
因为：settings.REST_FRAMEWORK提示是dict，应该用：
logger.info('settings.REST_FRAMEWORK["PAGE_SIZE"]=%s', settings.REST_FRAMEWORK["PAGE_SIZE"])
page = request.query_params.get('page', 1)
page_size = request.query_params.get('page_size', settings.REST_FRAMEWORK["PAGE_SIZE"])然后就可以了：
INFO|20180810 21:29:13|views:list:106|settings.REST_FRAMEWORK["PAGE_SIZE"]=20
【总结】
Django中引用当前配置其实就是：
from django.conf import settings
不过对于：
REST_FRAMEWORK = {
'PAGE_SIZE': 20,
}的写法，注意不是：
settings.REST_FRAMEWORK.PAGE_SIZE
而是：
settings.REST_FRAMEWORK[" PAGE_SIZE "]
因为：settings.REST_FRAMEWORK是个dict。
