问题 Meteor has a loginWithToken method, and there are resume tokens in the user object. So one can login using one of these tokens with loginWithToken . That works.

问题 I am trying to setup Meteor to use pm2 (https://github.com/Unitech/pm2) instead of forever as the node process monitor. I have had no luck in getting the environment variables that a Meteor application needs to be seen by the pm2 process.

If the only varible that represents current item is this . {{#each by_width}} {{#each by_height}} {{this}} // how do refer to this from the outer loop? {{/each}} {{/each}} 回答1: You can use ../ to access the parent in a Handlebars template: {{#each by_width}} {{#each by_height}} w: {{../this}} h: {{this}} {{/each}} {{/each}} That of course assumes that by_height is inside each element of by_width , if they're both at the

问题 How do you perform database migrations with Meteor? With Ruby on Rails there is ActiveRecord::Migration. Is there an equivalent mechanism in Meteor? For example, I make an app with some user data. I'm storing the data in Mongo using a JSON format. The app changes, and the JSON database schema needs to change. I can write a migration method to change the schema, however, I only want this to run if the server database is out of date. 回答1: There's nothing built in for this. What I've done myself
