Sails填充字段不会返回正确的结果
我有一个像这样的用户模型：
/**
* User.js
*
* @description :: TODO: You might write a short summary of how this model works and what it represents here.
* @docs :: http://sailsjs.org/#!documentation/models
*/
module.exports = {
attributes: {
firstName: 'string',
lastName: 'string',
fullName: {
type: 'string',
index: true
},
loginMethod: 'integer',
emailAddress: {
type: 'string',
unique: true
},
password: 'string',
friends: {
collection: 'User'
},
tallys: {
collection: 'Tally',
via: 'associatedUser'
},
friendsTallys: {
collection: 'Tally',
via: 'invitedUsers'
},
toJson: function() {
var obj = this.toObject();
delete obj.friends;
delete obj.tallys;
delete obj.friendsTallys;
return obj;
}
},
beforeCreate: function(values, cb) {
// Set the full name property using the first name and the last name
values.fullName = values.firstName + " " + values.lastName;
cb();
}
};
我有一个像这样的Tally模型：
/**
* Tally.js
*
* @description :: TODO: You might write a short summary of how this model works and what it represents here.
* @docs :: http://sailsjs.org/#!documentation/models
*/
module.exports = {
attributes: {
associatedUser: {
model: 'User'
},
type: 'integer',
yesThisCount: 'integer',
noThatCount: 'integer',
caption: 'string',
photos: {
collection: 'Photo'
},
invitedUsers: {
collection: 'User'
}
}
};
我有一个像这样的bootstrap js文件：
/**
* Bootstrap
* (sails.config.bootstrap)
*
* An asynchronous bootstrap function that runs before your Sails app gets lifted.
* This gives you an opportunity to set up your data model, run jobs, or perform some special logic.
*
* For more information on bootstrapping your app, check out:
* http://sailsjs.org/#/documentation/reference/sails.config/sails.config.bootstrap.html
*/
var async = require('async');
module.exports.bootstrap = function(cb) {
// It's very important to trigger this callback method when you are finished
// with the bootstrap! (otherwise your server will never lift, since it's waiting on the bootstrap)
/**
* Make some fake users for testing
* These will not be used for logging in.
* This is just to check addFriend and searching

我有一个登录方法，如下所示：

.populate("tallys")
.populate('friendsTallys')
.populate('friends')
.exec(function(err, found) {
if(err) {

return res.serverError({error: sails.config.errors.SERVER_ERROR});
}
if(found == null) {
sails.log.info("Could not find user with email address: " + user.emailAddress);
return res.badRequest({error: sails.config.errors.INVALID_EMAIL});
}
if(found && found.loginMethod != user.loginMethod)
{
sails.log.info("The user tried to login using the wrong method!");
return res.badRequest({error: sails.config.errors.INVALID_LOGIN_METHOD});
}
var friends = found.friends;
var friendsTallysIds = _.pluck(found.friendsTallys, 'id');
// We populated tallys and friendsTallys but we need to get the fields in those tallys to be populated so we have to query directly for the Tallys
Tally.find(_.pluck(found.tallys, 'id'))
.populate('associatedUser')
.populate('invitedUsers')
.populate('photos')
.exec(function(err, tallys) {
if(err){
sails.log.error("There was an error getting the tallys for the user: " + JSON.stringify(err));
return res.serverError({error: sails.config.errors.SERVER_ERROR});
}
if(tallys == null)
{
tallys = [];
}
Tally.find(_.pluck(found.friendsTallys, 'id'))
.populate('associatedUser')
.populate('invitedUsers')
.populate('photos')
.exec(function(err, friendsTallys) {
if(err){
sails.log.error("There was an error getting the friends' tallys for the user: " + JSON.stringify(err));
return res.serverError({error: sails.config.errors.SERVER_ERROR});
}
if(friendsTallys == null)
{
friendsTallys = [];
}
sails.log.info("The user was found: " + user.emailAddress);
// Generate an auth token for the user
var userAuthToken = EncryptionService.generateUserAuthToken(found);
// Set the token in the response headers
res.set('userAuthToken', userAuthToken);
// Remove the tallys, friendTallys, friends from the found object
// Subscribe the user to this own model
User.subscribe(req.socket, found);
// Subscribe to own tallys
Tally.subscribe(req.socket, tallys);
// Subscribe to Friends' Tallys
Tally.subscribe(req.socket, friendsTallys);
// Send the response
res.json({
user: found,
tallys: tallys,
friendsTallys: friendsTallys,
friends: friends
});
});
});
});
}
我的问题是我的用户对象中的friendsTallys字段只显示了2个标记，实际上应该有8个标记，因为我为每个用户创建了2个标记，然后为每个标记邀请所有其他用户。此外，在Tallys领域，在friendsTalls中的那两个标记是相同的标记。这是我断点的一个视图：
感谢您的帮助。如果您需要更多信息/代码/上下文，请告诉我。
