I have seen some similar questions related to this but have not found an answer.
I am attempting to create a Gallery in my Keystone Project that is similar to a post, where there will be a list of galleries and in it a gallery with a set of selected images:
var keystone = require('keystone'),
Types = keystone.Field.Types;
/**
* Gallery Model
* =============
*/
var Gallery = new keystone.List('Gallery', {
map: { name: 'name' },
autokey: { path: 'slug', from: 'name', unique: true }
});
Gallery.add({
name: { type: String, required: true},
published: {type: Types.Select, options: 'yes, no', default: 'no', index: true},
publishedDate: { type: Types.Date, index: true, dependsOn: { published: 'yes' } },
description: { type: String },
heroImage : { type: Types.Relationship, ref: 'Image' },
images : { type: Types.Relationship, ref: 'Image', many: true }
});
Gallery.defaultColumns = 'title, published|20%, publishedDate|20%';
Gallery.register();
I am able to create one gallery successfully - but any subsequent galleries throw the error:
There was an error saving your changes: insertDocument :: caused by ::
11000 E11000 duplicate key error index: site-name.galleries.$key_1 dup
key: { : null } (MongoError)
I am at a loss for what I need to change to this model to allow unique slugs for my galleries to be directly linked to etc.
Completely delete the model from MongoDB and restart. I typically see this error when making changes to a model with indexes that have been defined previously
with insert new item,you should set an default value for 'name', because name is set unique=true.
in my case, key is set to unique.
before:
MongoDB Enterprise > db.categories.save({_id: 89,name: 'xxx'})
WriteResult({
"nMatched" : 0,
"nUpserted" : 0,
"nModified" : 0,
"writeError" : {
"code" : 11000,
"errmsg" : "E11000 duplicate key error collection: sku.productcategories index: key_1 dup key: { : null }"
}
})
after:
MongoDB Enterprise > db.categories.save({_id: 89,name: 'xxx', key:'xx'})
WriteResult({ "nMatched" : 0, "nUpserted" : 1, "nModified" : 0, "_id" : 89 })

Hello community :) I implemented lots of good working functionality with firebase -> realm. Now i tried to edit a structure and I am running through the wildest error messages.
What is right for sure:
Firebase sends the data
Data is Converted (e.g. Firebase has "brands" as array -> is converted to a string for Realm Schema)
The error appears when firebase updates
Not every firebase content has all fields (e.g. Like you can see out of Realm Schema some fields are optional: true)
Fields where i maybe expect an issue:
Maybe its not possible to say that the ReferentList is optional (or i implemented it wrong): See Realm Schema const ReferentsList
What i tried
Debug before realm.create (Realm set) Result: Every data came in the right format
Checked all input values if they are int, string, ...
Hopefully someone can help me here because i got completely stuck with this issue and its necesarry to continue for my project. I want to know:
The solution why or what to do
A posibility to debug realm in a better way
Thank you in advance for your time and help :)

return {id};
})
}
realm.create('Events', obj, true);
});
}
Solved:!
The issue got solved through wrong data at firebase. Some Date Objects hasent been set correct.
How i got to the solution
When i tried to debugg the code i made a try/catch block around:
try{
realm.create('Events', obj, true);
}catch(error){
console.log(obj);
console.log(error);
}
Through this debug i found the right data wich was wrong. Before it just showed me all objects and afterwards the error.
I wont close this question because of the chance to help someone with the same issues.-
So I've been at this for awhile and can't see how my code is different from the documentation.
I've also checked out this question, this question, this question, and this unanswered different question.
For my admin panel I'm trying to query to get all the information associated with a user and display a 'master' user profile to the admin.
My User model looks like this:
module.exports = {
autoPK: true,
attributes : {
id: {
type: 'integer',
primaryKey: true,
unique: true
},
email : {
type : 'email',
unique : true,
required : true,
},
password : {
type : 'string',
minLength : 8,
required : true
},
admin:{
type: 'bool'
},
user_profile:{
collection: 'userprofile',
via: 'user_id',
},
properties: {
collection: 'subjectproperties',
via: 'user_id'
},
employment_info: {
collection: 'employmentinfo',
via: 'user_id'
},
file_uploads: {
collection: 'fileupload',
via: 'user_id'
},
nearest_living_relatives:{
collection: 'nearestlivingrelative',
via: 'user_id'
},
mortgage_info: {
collection: 'mortgageinfo',
via: 'user_id'
},
user_progression_state:{
collection: 'userprogressionstate',
via: 'user_id'
},
users_applied_loan_values:{
collection: 'usersappliedloanvalues',
via: 'user_id'
}
}
}
I don't want to list out all the belongs to user models cause there are a lot of them, but here is one of the simpler one's.
EmploymentInfo.js
module.exports = {
tableName: "employment_info",
attributes : {
employers_name:{
type: 'string',
required: true
},
employers_address:{
type: 'string',
required: true
},
employers_city:{
type: 'string',
required: true
},
employers_state:{
type: 'string',
required: true
},
employers_zip:{
type: 'string',
required: true
},
job_position:{
type: 'string',
required: true
},
years_in_position:{
type: 'string',
required: true
},
years_in_industry:{
type: 'integer',
required: true
},
user_id:{
model:'user'
}
}
};
And as for my controller:
create_admin_user_profile: function(req, res){
var user_id = req.query.userId;
User.find({'id': user_id}).populateAll().exec(function(err, user){
if(err || user.length === 0){
sails.log.verbose(err);
}else{
sails.log.verbose(user);
}
});
},
It doesn't error out but all I see in the terminal is this for the above:
[ { user_profile: [],
properties: [],
employment_info: [],
file_uploads: [],
nearest_living_relatives: [],
mortgage_info: [],
user_progression_state: [],
users_applied_loan_values: [],
id: 5,
email: 'test#test.com',
admin: 1 } ]
Even though there is an entry in all of those tables for that user.
If I change the line:
User.find({'id': user_id}).populateAll().exec(function(err, user){
To:
User.find({'id': user_id}).populate('employment_info').exec(function(err, user){
Same but shorter result:
[ { employment_info: [],
id: 5,
email: 'test#test.com',
admin: 1 } ]
I've tried changing the case, I've tried adding columnName to the user_id attribute, I've tried changing the column name across the entire breadth of the project to not have an under_score in it, though that never seemed to be issue in it picking up the names correctly, but nothing I've done seems to work. I've also tried uninstalling sails, and the sails-mysql adapter and clearing my npm cache.
At this point my just stuck, I really can't see a reason why it's not working.
As for project info:
Sails v: 0.12.11
npm v: 3.10.9
node v: 7.2.0
Additional info asked for in comments:
SQL row taken right from db for user 5
employers_name, employers_address, employers_city, employers_state, employers_zip, job_position, years_in_position, years_in_industry, user_id
'Company', 'Mill Steet', 'SLC', 'Utah', '88888', 'Developer', '2', '2', '5'
And json format returned by find method in EmploymentInfo.js controller
{
"employmentInfo": {
"employers_name": "Company",
"employers_address": "Mill Steet",
"employers_city": "SLC",
"employers_state": "Utah",
"employers_zip": "88888",
"job_position": "Developer",
"years_in_position": "2",
"years_in_industry": 2,
"user": 5
}
}
The reason the last param is user and not user_id is because I rename it in the find method to serve the front-end mvc which also has the ability to work with associations. It's also why the JSON has the format it does.
Code from the find method that replaces user_id:
EmploymentInfo.find({'user_id': user_id}).exec(function(err, profile){
if(err || !profile.length){
return res.json(err);
}else{
res.status(200);
profile[0].user = profile[0].user_id;
delete profile[0].user_id;
res.send({'employmentInfo': profile[0]});
}
});
However I've tried not renaming it; I've also tried getting rid of my find override and just relying on the blueprint find method, neither of those worked either.
I wrote an app using Sails.js with mongoDb(sails-mongo).
Firstly, I decided to write all to a single document...
And database slowed on 5GB of data..
"Slowed" means that basic find query executed in 30-50s..
Than I rewrite all in an multiple collections and add indexing..
example of my models:
Markets.js
module.exports = {
attributes: {
name: {
type: 'string',
index: true
},
pairs: {
collection: 'Exchanges',
via: 'source',
}
}
};
and Exchanges.js
module.exports = {
attributes: {
s1: {
type: "string"
},
source:{
model: "Maklers",
index: true
},
s2: {
type: "string"
},
p: {
type: 'float'
},
v1: {
type: 'float'
},
v2: {
type: 'float'
},
vb: {
type: 'float'
}
}
};
and example of slow query
Markets.findOne({
name: info,
sort: 'createdAt DESC',
limit: 1,
createdAt: {
'<=': aft
}
}).populateAll().exec(function(err, items) {
callback(err, items);
});
result of db.stats
> db.stats()
{

"collections" : 8,
"objects" : 36620661,
"avgObjSize" : 238.26556139988844,

}
What you can advice me?
It`s about 2000 of records every minute..
How to increase perfomance?
Change db config? Change indexes? Change DB? Change models/collections config?
I using 2-core server with 2GB of Virtual Memory..
Sorry for bad english..
There is a drawback in the 0.12 version of Waterline when using mongodb. By default waterline is not case sensitive, and mongodb is!
Your queries are slow, because when searching strings, it is being used a REGEX to find any case, so your indexes are useless. But you can change it, by disabling the case sensitiveness with the wlnex attribute:
someMongodbServer: {
adapter: 'sails-mongo',
host: 'mongodb',
port: 27017,
user: 'username',
password: 'password',
database: 'databaseCoolName',
wlNext: {
caseSensitive: true
}
},
You can confirm this error by checking on the mongodb logs. And see what are the slow queries.
I post here , because I recently start a development project with sails and MongoDB 3.0.2.
I am a beginner with this framework and his ORM (aka waterline).
In my project I've two classes : listeners and titles, and I need to do this relations :
N Listeners can add to her favorite N titles -> Many to Many.
This is the sample of my classes :
Listeners :
module.exports = {
schema : true,
autoPK : false,
attributes: {
name : {
type: 'string' ,
required : true,
string : true,
notNull:true
},
email : {
type: 'email' ,
required : true,
email :true,
notNull:true,
unique: true,
primaryKey:true
},
password : {
type: 'string',
required : true,
string:true,
minLength : 6,
notNull:true
},
favorites:{
collection :"title",
via : "bookmarkedBy",
dominant: true
}
//....
addFavoriteTitle:function(userID,titleID,callback){
User.findOne(userID).exec(function(error, user) {
if(!error && user){
user.favorites.add(titleID);
user.save(function(error) {});
callback(error,user);
} else{
callback(error,user);
}
});
},
}
Titles :
module.exports = {
schema : true,
autoPK : false,
attributes: {
title : {
type: 'string',
required : true,
//string : true,
notNull:true,
unique : true,
primaryKey:true
},
artist : {
type: 'string',
required : true,
string : true,
notNull:true
},
artwork : {
type: 'string'
},
playing:{
type:'boolean',
defaultsTo:false
},
bookmarkedBy:{
collection : "user",
via : "favorites"
},
},
//.....
}
I followed the official documention of sails, but I don't see / undestand :
How to recover the information on a title from the information contained in the relationship: " favorites" of the user class .
And how do from the relationship " bookmarkedBy " Class Title , to find / access information on a user who has the title in his "favorites".
So, I fail to use the relationship between the two classes , even according to the documentation.
Can you help me ?
I'm running into an issue with beforeValidate(), and can't find any answers online. My model has two relationship attributes that require id numbers in POSTed data. If a user POST strings instead, they get a validation error. I want to enable the user to POST string data, then inside beforeValidate() use findOrCreate() to find or create the attribute's related model, then overwrite the POSTed data's attribute with the relate model's ID.
I have the following model:
attributes: {
reporter : { model: 'reporter', required: true },
location : { model: 'location', required: true },
line : { type: 'boolean', required: true, defaultsTo: true },
count : { type: 'int', required: true, defaultsTo: 0},
composition : { type: 'int', required: true, defaultsTo: 3}
},
beforeValidate: function(values, next) {
if (typeof values.reporter !== 'number') {
Reporter.findOrCreate({name: values.reporter}).exec(function(data){
console.log(data)
values.reporter = data.id;
})
};
next();
},
I'm POSTing this data to the model's create() default blueprint endpoint:
{
"location":"Harry's",
"reporter":"tim",
"count":30,
"composition":3,
"line":false
}
When I log the above values inside beforeValidate(), I get this:
{ location: NaN,
reporter: NaN,
count: '30',
composition: '3',
line: false }
When I replace "location" and "reporter" with ID's, I don't get any errors. Why are the string values getting stripped out in the beforeValidate() function?
maybe u need POST(create) to endpoint location model, then POST(create) to reporter model, and then POST YOUMODEL/id/reporterID, POST YOUMODEL/id/location ID
