Express.js hbs module - register partials from .hbs file
提问by swatkins
I'm using the handlebars.js hbs wrapperin express.js. I have templates working fine, but I'm needing to add in partials to be rendered with my views.
我在express.js 中使用 handlebars.js hbs 包装器。我的模板工作正常，但我需要添加要使用我的视图呈现的部分。
I'd like to do something like this:
我想做这样的事情：
hbs.registerPartial('headPartial', 'header');
// where "header" is an .hbs file in my views folder
However, it's throwing a "header partial can not be found".
但是，它抛出“找不到标题部分”。
I can make the registerPartial work if I pass a string of html to the second param, but I'd like to use separate view files for my partials.
如果我将一串 html 传递给第二个参数，我可以使 registerPartial 工作，但我想为我的部分使用单独的视图文件。
I haven't found any documentation on this, but hoping I may just be missing something easy.
我还没有找到任何关于此的文档，但希望我可能只是遗漏了一些简单的东西。
Does anyone know how to use view files in the registerPartial method? If so, how do I implement this?
有谁知道如何在 registerPartial 方法中使用视图文件？如果是这样，我该如何实施？
UPDATE
更新
To give more context, let me add more code. Here is my "server" file - app.js
为了提供更多上下文，让我添加更多代码。这是我的“服务器”文件 - app.js
var express = require('express')
, routes = require('./routes')
, hbs = require('hbs');
var app = module.exports = express.createServer();
// Configuration
app.configure(function(){
app.set('views', __dirname + '/views');
app.set('view engine', 'hbs');
app.use(express.bodyParser());
app.use(express.methodOverride());
app.use(app.router);
app.use(express.static(__dirname + '/public'));
});
app.configure('development', function(){
app.use(express.errorHandler({ dumpExceptions: true, showStack: true }));
});
app.configure('production', function(){
app.use(express.errorHandler());
});
// this is the line that generates the error
hbs.registerPartial('headPartial', 'header');
// What I'm expecting is for "headPartial" to be a compiled template partial
// of the template within views/header.hbs, but it is not loading this way.
// If I do something like hbs.registerPartial('headPartial', '<p>test</p>');
// then it does work. I need to know how to pass an .hbs file to the
// registerPartial method.
// Routes
app.get('/', routes.index);
app.listen(3000);
And here is my routes.index file:
这是我的 routes.index 文件：
exports.index = function(req, res){
res.render('index', { title: 'Express' })
};
In my views folder, I have three templates:
在我的视图文件夹中，我有三个模板：
views/
header.hbs (this is my partial)
index.hbs
layout.hbs
In my index.hbs file, I'm calling the 'headPartial' partial with:
在我的 index.hbs 文件中，我调用了“headPartial”部分：
{{> headPartial}}
Any help is greatly appreciated.
任何帮助是极大的赞赏。

This codeloads all the partial templates in a directory and makes them available by filename:
此代码加载目录中的所有部分模板，并按文件名使它们可用：
var hbs = require('hbs');
var fs = require('fs');
var partialsDir = __dirname + '/../views/partials';
var filenames = fs.readdirSync(partialsDir);
filenames.forEach(function (filename) {
var matches = /^([^.]+).hbs$/.exec(filename);
if (!matches) {
return;
}
var name = matches[1];
var template = fs.readFileSync(partialsDir + '/' + filename, 'utf8');
hbs.registerPartial(name, template);
});

For convenience, registerPartials provides a quick way to load all partials from a specific directory:
为方便起见， registerPartials 提供了一种从特定目录加载所有部分的快速方法：
var hbs = require('hbs');
hbs.registerPartials(__dirname + '/views/partials');
Partials that are loaded from a directory are named based on their filename, where spaces and hyphens are replaced with an underscore character:
从目录加载的部分根据其文件名命名，其中空格和连字符替换为下划线字符：
template.html -> {{> template}}
template 2.html -> {{> template_2}}
login view.hbs -> {{> login_view}}
template-file.html -> {{> template_file}}
Cheers!
干杯!

Looks like creating a variable and pulling in the template code manually works:
看起来像创建一个变量并手动拉入模板代码工作：
var hbs = require('hbs')
, fs = require('fs')
, headerTemplate = fs.readFileSync(__dirname + '/views/_header.hbs', 'utf8');
and later:
然后：
hbs.registerPartial('headPartial', headerTemplate);

For me I had template file my-partial.hbs
对我来说，我有模板文件 my-partial.hbs
Then I tried to access them via:
然后我尝试通过以下方式访问它们：
{{> my-partial }}
But the partial was stored in hbs as my_partial regardless of the filename.
但是无论文件名如何，部分都作为 my_partial 存储在 hbs 中。
This is thanks to hbs version 3.1.0 line 218
这要归功于 hbs version 3.1.0 line 218
.slice(0, -(ext.length)).replace(/[ -]/g, '_').replace('\', '/');

For me, I have a function like:
对我来说，我有一个类似的功能：
var hbs = require('hbs');
var fs = require('fs');
var statupfunc = {
registerHbsPartials : function(){
//this is run when app start
hbs.registerPartials(__dirname + "/" + resource.src.views + '/partials');
},
registerOneHbsPartials : function(event){
//this is run for gulp watch
if(event.type == 'deleted')
{
return;
}
var filename = event.path;
var matches = /^.*\(.+?)\.hbs$/.exec(filename);
if (!matches) {
return;
}
var name = matches[1];
var template = fs.readFileSync(filename, 'utf8');
hbs.registerPartial(name, template);
}
};
Run statupfunc.registerHbsPartialsat app startup and then register gulp watch with statupfunc.registerOneHbsPartialsto register partials on new creation
在应用程序启动时运行statupfunc.registerHbsPartials，然后使用statupfunc.registerOneHbsPartials注册gulp watch以在新创建时注册部分
gulp.task('watch', function() {
gulp.watch(resource.src.views + '/partials/*.*', statupfunc.registerOneHbsPartials);
});
