Lib从一个viewset逐行评测所有方法
drf-viewset-profiler的Python项目详细描述
drf视图集分析器
Decorator逐行分析视图集（及其序列化程序）中的所有方法。对于请求期间调用的所有方法，输出 将生成显示点击数、时间（以秒为单位）、行和已执行方法的每行内容
安装
pip install drf-viewset-profiler
使用
装饰要分析的视图集
fromdrf_viewset_profilerimportline_profiler_viewset@line_profiler_viewsetclassSomeViewSet(ViewSet):queryset=Model.objects.all()
在中设置中间件配置设置.py在
^{pr2}$在此视图集中发出请求以分析和测量浪费的时间（以秒为单位）
配置
DRF_VIEWSET_PROFILER={"DEFAULT_OUTPUT_GENERATION_TYPE":"drf_viewset_profiler.output.FileOutput","DEFAULT_OUTPUT_LOCATION":"","ENABLE_SERIALIZER_PROFILER":True}
默认输出生成类型
- drf视图集_profiler.output.FileOutput：在txt文件中生成带有已分析视图集名称的输出
- drf视图集_探查器.output.StdOutput：在控制台中生成输出（默认）
可以通过扩展baseoutput类进行自定义
默认输出位置
- 使用要分析的视图的名称生成输出文件的位置（默认值为空）
启用\u SERIALIZER_PROFILER
- 分析序列化程序中与视图集关联的方法（默认值为True）
