如何在SailsJS中将视图渲染为字符串？ [英] How to render a view into a string in SailsJS?

问题描述

在一个控制器中，我想呈现具有特定布局的特定视图以发送包含结果字符串的电子邮件，但是显然我不需要向用户显示结果。有没有办法使用我用来渲染视图的EJS引擎来实现此目的？这是我简化的控制器操作：

In one controller I want to render a certain view with a certain layout to send an email with the resulting string, but I obviously do not need to show the result to the user. Is there a way to use the EJS engine that I'm using to render views to achieve this? Here's my a bit simplified controller action:

  setEmail: function(req, res) {
    var update = {
      activationToken: _getToken(),
      email: req.param('email')
    };

    Profile.update(res.locals.profile.id, update).then(function(profile) {
      res.redirect(profileUrl);
      mailer.sendActivationEmail(
        update.email,
        res.i18n('Подтвердите свой адрес электронной почты'),
        emailString); // <=== Here is where I need the string rendered from a view
    });
  },

推荐答案

使用视图挂钩

Profile.update(res.locals.profile.id, update).then(function(profile) {
  res.redirect(profileUrl);

  sails.hooks.views.render("viewname",profile, function(err,html){
     if(err) return console.log(err);

     mailer.sendActivationEmail(
       update.email,
       res.i18n('Подтвердите свой адрес электронной почты'),
       html
     );
    })

});
