我从Docker开始,但我不知道如何配置PyCharm以使用位于容器中的python解释器.
使用Vagrant很容易设置,但显然没有正式的方法来使用Docker.
我应该使用暴露的ssh端口准备特殊的Docker镜像吗？如何更容易地做到这一点？
我在我的项目中完成了以下post_save信号.
from django.db.models.signals import post_save
from django.contrib.auth.models import User
# CORE - SIGNALS
# Core Signals will operate based on post
def after_save_handler_attr_audit_obj(sender, **kwargs):
print User.get_profile()
if hasattr(kwargs['instance'], 'audit_obj'):
if kwargs['created']:
kwargs['instance'].audit_obj.create(operation="INSERT", operation_by=**USER.ID**).save()
else:
kwargs['instance'].audit_obj.create(operation="UPDATE").save()
# Connect the handler with the post save signal - Django 1.2
post_save.connect(after_save_handler_attr_audit_obj, dispatch_uid="core.models.audit.new")
在operation_by列中,我想获取user_id并存储它.知道如何做到这一点？

我很难理解一些Jinja指令是如何起作用的.为了运行一些测试(最终,分享结果,jsfiddle风格),我真的很感激有一些在线解析器,但在Web上找不到任何东西.
它甚至存在吗？
如果用户上传图像,并使用PIL调整大小,我会得到一个PIL Image对象.
PIL Image在将文件保存到数据库之前,如何在模板中显示文件？它甚至可以作为图像传递并渲染吗？
