bookshelf.js未加载关系

Question

Im new to bookshelfjs and i want to get the data from other table using the ID from other table. Im using this sample data:

/* User's Table */
----------------+-------------------+----------
   lastname     |    firstname      |   id  
----------------+-------------------+---------
Dela Cruz          Juan                1
Pendoku            Pedro               2

/* Logs's Table */
----------------+--------------+----------
     userid     |    time      |   id  
----------------+--------------+---------
  1                 8:00           1
  2                12:00           2
  1                 9:00           3

Question: how i can query the logs of specific user thru bookshelf.js?

so the result should be like this:

----------------+--------------+----------
     lastname   |    time      |   id  
----------------+--------------+---------
 Dela Cruz          8:00           1
 Dela Cruz          9:00           3

My query:

new User({'lastname': 'Dela Cruz'})
  .logs()
  .fetch()
  .then(function(timelog) {
    console.log(timelog.toJSON());
}); 

My models

var User, Log;

User = bookshelf.Model.extend({
  tableName:'user',
  logs: function() {
     return this.hasMany(Log, 'userid');
  }
});

Log = bookshelf.Model.extend({
  tableName:'log',
  user: function(){
    return this.belongsTo(User, 'userid');
  }
});

Log Error:

{ __cid: '__cid1',
  method: 'select',
  options: undefined,
  bindings: [undefined],
  sql: 'select log.* from log where log.userid = ?'
}

Answer 1

Change the user model to this:

User = bookshelf.Model.extend({
  tableName:'user',
  logs: function() {
     return this.hasMany(Log);
  }
});

And try this

new User({'lastname': 'Dela Cruz'})
  .fetch({withRelated:['logs']})
  .then(function(timelog) {
    console.log(timelog.toJSON());
}); 

Answer 2

Try adding the {idAttribute: 'UserId'} to your User model I found mine was case sensitive to the FieldNames so 'userid' resulted in no returned data but 'UserId' did. So make sure it matches the field in your db

So change your model to

User = bookshelf.Model.extend({
  tableName:'user',
  idAttribute: 'userid',
  logs: function() {
     return this.hasMany(Log);
  }
});

And try the query as shown in uglycode's answer
