Log all SQL queries in your Django app
This article will guide you on how to effectively log all SQL queries executed by your Django application, including queries from the admin site. The key is to modify the settings.py
field in the LOGGING
file.
Implementation steps:
logging
library into your code. This allows you to configure and handle logging functionality. import logging
class QueryHandler(logging.Handler): def emit(self, record): # 自定义处理SQL查询的逻辑 pass
settings.py
field in the LOGGING
file. This will enable SQL query logging and direct output to the defined processor. LOGGING = { 'version': 1, 'filters': { 'require_debug_true': { '()': 'django.utils.log.RequireDebugTrue', } }, 'handlers': { 'console': { 'level': 'DEBUG', 'filters': ['require_debug_true'], 'class': 'logging.StreamHandler', }, 'query_handler': { 'level': 'DEBUG', 'filters': [], 'class': 'path.to.QueryHandler', # 将path.to.QueryHandler替换为您的自定义处理器的路径 } }, 'loggers': { 'django.db.backends': { 'level': 'DEBUG', 'handlers': ['query_handler'], } } }
logger = logging.getLogger('django.db.backends')
logger.debug(sql_query)
By following these steps and incorporating the provided code snippets into your settings.py
file, Django will log all SQL queries to the specified log file, providing a comprehensive overview of all database interactions. Remember to replace 'path.to.QueryHandler'
with the actual path to your custom processor. If you don't need a custom processor, you can remove the 'query_handler'
part and keep only the 'console'
processor.
