web2py - 使用锚标记回调时不会调用控制器函数 [英] web2py - Controller function isn't called when using anchor tag callback

问题描述

当用户访问杂志页面时，应该会出现一个按钮，允许当前登录的用户订阅特定杂志(如果该用户已经登录).匿名用户不应看到该按钮.

我已经让按钮在用户登录后显示，但点击按钮不会调用我的控制器功能.

如果这是控制器功能:

@auth.requires_login()定义订阅():mag_id = request.args(0, cast=int)db.subscribe.insert(杂志=mag_id，订阅者=auth.user.id)

这是视图的一部分:

{{=magazine.title}}{{=magazine.description}}
<div>{{ 如果 auth.is_logged_in():}}{{=A('subscribe', _class="btn_subscribe", callback=URL("subscribe", args=magazine.id))}}{{经过}}

按钮显示如下:

<a href="#null" onclick="ajax('/myapp/default/subscribe/3',[],'me');return false">subscribe</a>

控制器函数永远不会被调用，用户也永远不会订阅.

解决方案

正如 Anthony 所建议的，添加 web2py.js 是解决方案.

When a user visits a magazine page, a button should appear that will allow the currently logged in user to subscribe to a particular magazine if that user is already logged in. The button should not be visible to an anonymous user.

I have gotten the button to show up when the user has logged in, but clicking on the button doesn't call my controller function.

If this is the controller function:

@auth.requires_login()
def subscribe():
    mag_id = request.args(0, cast=int)
    db.subscribe.insert(magazine=mag_id, subscriber=auth.user.id)

And this is the part of the views:

<div>
    {{=magazine.title}}
    {{=magazine.description}}
</div>

<div>
{{ if auth.is_logged_in():}}
    {{=A('subscribe', _class="btn_subscribe", callback=URL("subscribe", args=magazine.id))}}
{{pass}}
</div>

The <a> button shows up as this:

<a href="#null" onclick="ajax('/myapp/default/subscribe/3',[],'me');return false">subscribe</a>

And the controller function is never called, and the user is never subscribed.

解决方案

As Anthony had suggested, adding the web2py.js was the solution.
