Create config variables in sails.js?
提问by user2688473
I'm converting an app of mine from Express to sails.js- is there a way I can do something like this in Sails?
我正在将我的一个应用程序从 Express 转换为sails.js- 有没有办法在 Sails 中做这样的事情？
From my app.jsfile in Express:
从我app.js在 Express 中的文件：
var globals = {
name: 'projectName',
author: 'authorName'
};
app.get('/', function (req, res) {
globals.page_title = 'Home';
res.render('index', globals);
});
This let me access those variables on every view without having to hardcode them into the template. Not sure how/where to do it in Sails though.
这让我可以在每个视图上访问这些变量，而无需将它们硬编码到模板中。不知道在 Sails 中如何/在哪里做。

You can create your own config file in config/folder. For example config/myconf.jswith your config variables:
您可以在config/文件夹中创建自己的配置文件。例如config/myconf.js使用您的配置变量：
module.exports.myconf = {
name: 'projectName',
author: 'authorName',
anyobject: {
bar: "foo"
}
};
and then access these variables from any view via global sailsvariable.
然后通过全局sails变量从任何视图访问这些变量。
In a view:
在一个观点：
<!-- views/foo/bar.ejs -->
<%= sails.config.myconf.name %>
<%= sails.config.myconf.author %>
In a service
在服务中
// api/services/FooService.js
module.exports = {
/**
* Some function that does stuff.
*
* @param {[type]} options [description]
* @param {Function} cb [description]
*/
lookupDumbledore: function(options, cb) {
// `sails` object is available here:
var conf = sails.config;
cb(null, conf.whatever);
}
};
// `sails` is not available out here
// (it doesn't exist yet)
console.log(sails); // ==> undefined
In a model:
在模型中：
// api/models/Foo.js
module.exports = {
attributes: {
// ...
},
someModelMethod: function (options, cb) {
// `sails` object is available here:
var conf = sails.config;
cb(null, conf.whatever);
}
};
// `sails is not available out here
// (doesn't exist yet)
In a controller:
在控制器中：
Note: This works the same way in policies.
注意：这在策略中的工作方式相同。
// api/controllers/FooController.js
module.exports = {
index: function (req, res) {
// `sails` is available in here
return res.json({
name: sails.config.myconf.name
});
}
};
// `sails is not available out here
// (doesn't exist yet)

I just made a service which delivers a value:
我刚刚制作了一项提供价值的服务：
maxLimbs: function(){
var maxLimbs = 15;
return maxLimbs;
}
