在Meteor.JS中创建第一个用户创建第二个用户

Question

How can we automatically create a second user when the user registers (the first user) from a form generated using the useraccounts:core package?

Running a Accounts.createUser from within Accounts.onCreateUSer causes an error Exception while invoking method 'ATCreateUserServer' TypeError: Cannot read property '_id' of undefined

Accounts.onCreateUser(function(options, user) {

    // Create Primary User
    if(!user.type) {

        // Set user.type as 'user'
        user.type = 'user'

        // Create Secondary User
        Accounts.createUser({
            username: options.profile.slaveName,
            password: options.profile.slaveName,
            type: 'slave',
            profile: {
                firstName: user.profile.firstName,
                lastName: user.profile.lastName
            }
        })

        user.profile = options.profile
        return user
    }


    // Create Secondary User
    if(user.type == 'slave') {
        user.profile = options.profile
        return user
    }

});

It looks to me like you're conflating the user argument and the options argument. For instance, the type field comes in through the options argument, not user .

The following code worked for me:

Accounts.onCreateUser(function(options, user) {
  // Create Primary User
  if(!options.type) {
    // Set user.type as 'user'
    options.type = 'user'

    // Create Secondary User
    Accounts.createUser({
        username: options.profile.slaveName,
        password: options.profile.slaveName,
        type: 'slave',
        profile: {
            firstName: options.profile.firstName,
            lastName: options.profile.lastName
        }
    });

    user.profile = options.profile
    return user
  }


  // Create Secondary User
  if(options.type == 'slave') {
    user.profile = options.profile
    return user
  }
});

I then tested like so:

// console
Accounts.createUser({username: "guest", password: "guest", profile: {slaveName: 'guestslave', firstName: "Greatest", lastName: "Ever"}})
Meteor.users.find({username: {$regex: 'guest'}}).fetch()
