Meteor, '/users/insert' is already defined

问题

I'm creating basic Administration Panel and I didn't work with MongoDB yet.

For development purposes I left autopublish and insecure in the project. In order to render users from database (Accounts-ui + Accounts-facebook) i need a handler for Users = new Mongo.Collection("users"); but during compilation there is following error:

'/users/insert' is already defined.

HTML

<body>
  {{> loginButtons}}

  {{#each users}}
    {{> user}}
  {{/each}}
</body>

<template name="user">
  <li>{{profile.name}}: {{_id}}</li>
</template>

Users = new Mongo.Collection("users");

if (Meteor.isClient) {

  Template.body.helpers({
    users: function () {
      return Users.find({});
    }
  });

  Accounts.onLogin(function(){
    console.log("logged in: " + Meteor.userId());
  });

}

if (Meteor.isServer) {
  Meteor.startup(function () {
    // code to run on server at startup
  });
}
