订阅同时列出所有用户和this.userId的Meteor.users（）

Question

PAGE CUSTOMERS: Lists all users in the users collection. PAGE PROFILE: List only logged in user profile information.

userProfiles.js:

 if (Meteor.isServer) {
   Meteor.publish("userData", function () {
    return Meteor.users.find({}, {
        fields: {
          // VISIBLE
          'profile.mobile': 1,
          'profile.zipcode': 1,
          'profile.first_name': 1,
          'profile.work_title': 1,
          'emails[0].address': 1,
        }});
    });
 }

profile.js

Template.profileDetails.helpers({
  user: function() {
    return Meteor.users.find({_id: this.userId});
  },

  userEmail: function() {
    return this.emails[0].address;
  },

  userFirstName: function() {
    return this.profile.first_name;
  },

  userTitle: function() {
    return this.profile.work_title;
  },

  userMobile: function() {
    return this.profile.mobile;
  },

  userZip: function() {
    return this.profile.zipcode;
  },
});

customers.js

Template.customerDetails.helpers({
  user: function() {
    return Meteor.users.find();
  },

  userEmail: function() {
    return this.emails[0].address;
  },

  userFirstName: function() {
    return this.profile.first_name;
  },

  userTitle: function() {
    return this.profile.work_title;
  },

  userMobile: function() {
    return this.profile.mobile;
  },

  userZip: function() {
    return this.profile.zipcode;
  },
});

The profile page is not showing any information at all. How can i get it to only display the logged in user information? Thank you!

Answer 1

the "this" in the helpers isn't the user. since you're looking for the current user in your profile template, you can do it in Blaze, without a helper:

{{currentUser.profile.first_name}}

for the customers, you can loop over the users returned by your helper. i would rename the helper:

Template.customerDetails.helpers({
  customers(){
    return Meteor.users.find({});
  }
});

then you can loop over them, in Blaze, like this:

{{#each customer in customers}}
  {{customer.profile.first_name}}
{{else}}
   No customers found.
{{/each}}

note that you don't need any other helpers to make that work.

Answer 2

To get the currently logged-in user, you could use: Meteor.user() :

//...
user: function() {
  return Meteor.user();
},
//...
