清理 web2py 我的控制器 [英] Cleaning up web2py my controllers

问题描述

我的 web2py 应用程序中的控制器有点混乱，我想将功能移到另一个地方.

My controllers are getting a bit cluttered in my web2py app, and I would like to move functions to another place.

我最初想将它们移动到模块中，但有时我会访问数据库，并且在 db.py 中设置了其他参数(我是用户 ID，现在是日期等).

I was initially thinking of moving them to modules, but I access the db sometimes, and have other parameters set in db.py (me for user id, now for the date, etc.).

是否有一种干净的方法可以将这些函数移动到新文件，同时仍然可以访问我需要的变量?我不反对像 from db import me, now

Is there a clean way to move these functions to a new file while still having access to the variables I need? I'm not opposed to something like from db import me, now

推荐答案

您的控制器操作(即出现在 URL 中的操作)必须是在控制器文件中定义的函数(即，您不能将它们移动到模块中).但是，如果您的控制器中有不是动作的功能，您可以将它们移动到模块中.假设您将从模型或控制器调用这些函数，您只需将 db、me 和 now 对象作为参数传递给这些函数.另一种选择是将它们添加到线程本地 current 对象中，该对象可以从模块访问.这样做:

You controller actions (i.e., the actions that appear in URLs) have to be functions defined in a controller file (i.e., you cannot move them to a module). However, if there are functions in your controller that are not actions, you may move those to a module. Assuming you will call those functions from a model or controller, you can simply pass your db, me, and now objects to those functions as arguments. Another option is to add them to the thread local current object, which can be accessed from modules. To do so:

在模型中:

from globals import current
current.app.db = db
# etc.

在模块中:

from globals import current

def func(*args):
    db=current.app.db
    # etc.
