django1.3在shell下,调试models变得更为简单了,不用像之前的版本,手工去调用django query,才能打印出之前的代码是执行的什么SQL语句. 1.3开始只需在settings.py里,配置如下logging即可: LOGGING = { 'version': 1, 'disable_existing_loggers': False, 'handlers': { 'console':{ 'level':'DEBUG', 'class':...
Of course, if you're stuck using a stable version of Django, you can get the same effect relatively easily by patching django/db/models/sql/compiler.py by adding this to the bottom of the import list: import logging _querylogger = logging.getLogger( 'sql.compiler' ) The find the SQLC...

下文将介绍如何在无需实际编写SQL语句的情况下,通过Python和相关工具来执行原始SQL命令。为此我们将使用Django的数据建模能力,但具体语法其实与Python中的SQLAlchemy包非常类似。 这就开始吧! 这是一个Django数据模型范例: class BlogArticle(models.Model):
from django.db import models from django.contrib.auth.models import User class Shows(models.Model): showid= models.CharField(max_length=10, unique=True, db_index=True) name = models.CharField(max_length=256, db_index=True) aka = models.CharField(max_length=256, db_index=True) score = ...

class Publisher(models.Model): name = models.CharField(max_length=128) address = models.CharField(max_length=256,null=True,blank=True) def __str__(self): return self.name class Meta(): verbose_name = "出版社" verbose_name_plural = "出版社" ...
created_time = models.DateTimeField(verbose_name='创建时间', auto_now_add=True) update_time = models.DateTimeField(verbose_name='更新时间', auto_now=True) def __str__(self): # 我们可以访问外键对象的属性,比如取所属设备名self.dev.name ...
django框架采用的ORM模型,我们可以通过mysql的日志记录实时查看执行的sql语句,具体步骤如下: 第一步:进入mysql,查看日志开启的状态和log文件路径; mysql>show variables like"%general_log%";+---+---+|Variable_name|Value|+---+---+|general_log|OFF||general_log_file|/var/lib/mysql/VIP.log|+---+...
