I use those filters on my user controller and they works just fine. But now the system needs to apply some of those filters only when the user is not an super user. how can i use the filter property to check if the user is a su? Here is the actual code:
#Crud({
model: {
type: User,
},
routes: {
createOneBase: {
returnShallow: true
},
updateOneBase: {
returnShallow: true,
},
replaceOneBase: {
returnShallow: true,
},
exclude: ['deleteOneBase', 'updateOneBase', 'createManyBase'],
},
params: {
id: {
field: 'id',
type: 'number',
primary: true,
},
},
query: {
join: {
createdBy: { eager: true, exclude: ['password'] },
updatedBy: { eager: true, exclude: ['password'] },
members: { eager: true, alias: 'groups' },
contacts: {eager: true, alias: 'contacts'},
'members.group': { eager: true },
userCompanies: { eager: true },
'userCompanies.companyId': { eager: true }
},
filter: {
exclude: {
$eq: false,
},
'contacts.exclude': {
$eq: false,
},
'userCompanies.exclude': {
$eq: false,
}
},
sort: [
{
field: 'id',
order: 'ASC',
}
]
}
})
The only one which will be applied no matter the user type is the exclude one.
I've solved by myself using the override method with ParsedRequest.
#Override('getManyBase')
async getMany(#ParsedRequest() req: CrudRequest, #UserReq() user: User) {
if(!user.su) {
req.parsed.filter.push({
field: 'contacts.exclude',
operator: '$eq',
value: false
},
{
field: 'userCompanies.exclude',
operator: '$eq',
value: false
})
}
return await this.service.getMany(req);
}

I'm trying to realize the query, where I can find all records, which at least one of the attributes includes the text, user send with request, for that I use where, but it can search, as I understand, in only own model, but i need it to search it in parent model and in associated filds together, not apart.
There is my models:
const Picture = sequelize.define<IPictureInstance>('picture', {
id: { type: DataTypes.INTEGER, primaryKey: true, autoIncrement: true },
img: { type: DataTypes.STRING, allowNull: false },
mainTitle: { type: DataTypes.STRING, allowNull: false },
description: { type: DataTypes.TEXT }
});
const PictureInfo = sequelize.define<IPictureInfoInstance>('pictureInfo', {
id: { type: DataTypes.INTEGER, primaryKey: true, autoIncrement: true },
title: { type: DataTypes.STRING, allowNull: false },
description: { type: DataTypes.STRING, allowNull: false }
});
const PictureTag = sequelize.define<IPictureTagInstance>('pictureTag', {
id: { type: DataTypes.INTEGER, primaryKey: true, autoIncrement: true },
text: { type: DataTypes.TEXT, allowNull: false }
});
const PicturesTags = sequelize.define<IPicturesTagsInstance>('picturesTags', {
id: { type: DataTypes.INTEGER, primaryKey: true, autoIncrement: true }
});
And their associations:
Picture.belongsToMany(PictureTag, { through: PicturesTags, as: "tags", onDelete: 'cascade' });
PictureTag.belongsToMany(Picture, { through: PicturesTags, as: "pictures", onDelete: 'cascade'
});
Picture.hasMany(PictureInfo, { onDelete: "cascade" });
PictureInfo.belongsTo(Picture);
That's what I tried to do:
static async getPictures(query: string | undefined) {
const pictures = await models.Picture.findAll({
where: {
[Op.or]: {
mainTitle: { [Op.iRegexp]: `${query}` },
description: { [Op.iRegexp]: `${query}` },
},
},
include: [
{
model: models.PictureInfo,
as: "pictureInfos",
where: {
[Op.or]: {
title: { [Op.iRegexp]: `${query}` },
description: { [Op.iRegexp]: `${query}` }
}
},
required: false
},
{
model: models.PictureTag,
as: "tags",
attributes: ["id", "text"],
where: { text: { [Op.iRegexp]: `${query}` } },
through: {
attributes: [],
},
required: false
}
],
});
return pictures;
}
But in this case, when it can't find records in first where param it returns an empty array, I understand it, but it isn't a behavior I need.
I need to check every attribute together.
So, if user send query=cat, it will check mainTitle and description, if there is nothing, it will check associated pictureInfos fields and after, if there is nothing, check pictureTags associated fields, that's what I need, will be grateful for the help.
My solution:
static async getPictures(query: string | undefined) {
const whereStatement = {
[Op.or]: {
mainTitle: { [Op.iRegexp]: `${query}` },
description: { [Op.iRegexp]: `${query}` },
"$tags.text$": { [Op.iRegexp]: `${query}` },
"$pictureInfos.title$": { [Op.iRegexp]: `${query}` },
"$pictureInfos.description$": { [Op.iRegexp]: `${query}` },
}
};
const pictures = await models.Picture.findAll({
where: whereStatement,
include: [
{
model: models.PictureInfo,
as: "pictureInfos",
},
{
model: models.PictureTag,
as: "tags",
}
],
});
return pictures;
}
But I'm still confused with those $ symbols, what they are for, I couldn't find the answer in documentation?

I am currently trying to setup a schema for custom Discord guild commands:
const GuildCommandsSchema = new mongoose.Schema({
_id: String,
commands: [
{
name: {
type: String,
unique: true,
required: true,
},
action: {
type: String,
required: true,
},
author: {
type: String,
required: true,
},
},
],
});
Is this ok, performancewise, or could I improve it?
I feel like Mongo would need to look through all commands, since it can't index any commands inside 'commands' even though 'name' is unique.
If that's fine, how can I access the values inside commands?
I would need to find the right command via 'name' if it exists, otherwise create it and add/update 'action' + 'author'.
I tried something like this:
const updatedCommand = await GuildCommands.findOneAndUpdate(
{ _id },
{
$set: {
[`commands.$[outer].name`]: name,
[`commands.$[outer].action`]: action,
[`commands.$[outer].author`]: author,
},
},
{
arrayFilters: [{ 'outer.name': name }],
}
);
Unfortunately that does not create commands if they don't exist.
Thanks for your help
aggregate
db.collection.update({},
{
$set: {
"commands.$[c].name": "1",
"commands.$[c].author": "1",
"commands.$[c].action": "1"
}
},
{
arrayFilters: [
{
"c.author": "34"
}
],
multi: true
})

To answer my own question:
I changed my Schema to use Maps instead of Arrays for performance improvments and also better model management.
const GuildCommandsSchema = new mongoose.Schema(
{
_id: String,
commands: {
type: Map,
of: {
_id: false,
name: {
type: String,
required: true,
},
action: {
type: String,
required: true,
},
active: {
type: Boolean,
required: true,
default: true,
},
author: {
type: String,
required: true,
},
},
},
},
{ versionKey: false }
);
The new query to find and update/create a command is also better imo:
const findCommand = await GuildCommands.findOne({ _id });
if (!action) {
const getCommand = findCommand.commands.get(name);
if (getCommand) {
message.reply(getCommand.action);
} else {
message.reply(`Cannot find ${name}`);
}
} else {
findCommand.commands.set(name, {
name,
action,
author,
});
findCommand.save();
}
This is what I have so far. This is my AnswerSchema with a comments array nested within that I am trying to update.
const AnswerSchema = new Schema({
user: {
type: Schema.Types.ObjectId,
ref: 'user',
},
question: {
type: Schema.Types.ObjectId,
ref: 'question',
},
text: {
type: String,
required: true,
},
name: {
type: String,
},
avatar: {
type: String,
},
views: {
type: Number,
},
date: {
type: Date,
default: Date.now,
},
answerLikes: [
{
user: {
type: Schema.Types.ObjectId,
ref: 'user',
},
},
],
comments: [
{
user: {
type: Schema.Types.ObjectId,
ref: 'user',
},
text: {
type: String,
required: true,
},
name: {
type: String,
},
avatar: {
type: String,
},
commentLikes: [
{
user: {
type: Schema.Types.ObjectId,
ref: 'user',
},
},
],
date: {
type: Date,
default: Date.now,
},
},
],
})
and here is my update route that I am trying to use to update the comments array text field
try {
const updatedAnswer = await Answer.findOneAndUpdate(
{ _id: req.params.answer_id },
{
$set: { 'comments.$[comment].text': formattedAnswer },
},
{
arrayFilters: [{'comment._id': req.params.comment_id }],
},
{ new: true }
)
res.json(updatedAnswer)
I keep getting the error 'Callback must be a function, got [object Object]' and cant figure out a fix.
Any ideas?
Thanks!
The problem in your code is that you are passing 4 parameters to the findOneAndUpdate function.
The 4th argument is a callback which accepts a function:
(err /* an error if occurred */, doc /* the updated document */) => {}
In order to solve that you need to combine your last 2 arguments into one object like:
{
arrayFilters: [{'comment._id': req.params.comment_id }],
new: true
}
Final query:
const updatedAnswer = await Answer.findOneAndUpdate(
{ _id: req.params.answer_id },
{
$set: { 'comments.$[comment].text': formattedAnswer },
},
{
arrayFilters: [{'comment._id': req.params.comment_id }],
new: true
}
)
The 4th argument in findOneAndUpdate function takes in a callback function that was where your error was.
Try this
try{
const updatedAnswer = await Answer.findOneAndUpdate(
{ _id: req.params.answer_id },
{
$set: { 'comments.$[comment].text': formattedAnswer },
},
{
arrayFilters: [{'comment._id': req.params.comment_id }],
new: true
}
);
res.json(updatedAnswer);
}catch(err){
//console.log(err)
}
I am trying to create an index on an existing table (Postgres) on a date column so that I can get the latest posts first
Model file feeditem.js
module.exports = (sequelize, DataTypes) => {

unique: false,
},
],
});
FeedItem.associate = (models) => {
// associations can be defined here
//...
};
return FeedItem;
};

// eslint-disable-next-line no-unused-vars

};
The migrations are run in perfect order where table is created first and index is added later.
Logging is enabled and when I check the logs
Expected:
It should create a DESC index on pubdate which goes like
CREATE INDEX "feed_items_pubdate_index" ON "feed_items" ("pubdate" DESC)
Actual Output
Executing (default): CREATE INDEX "feed_items_pubdate_index" ON "feed_items" ("pubdate")
Any ideas what is going wrong here?
Your question is still relevant because it is undocumented.
The proper way to define index in descending order is extended definition in fields argument.
So the migration file add-index.js should look like:
module.exports = {
...
up: (queryInterface, Sequelize) => queryInterface.addIndex(
'feed_items',
[{
attribute: 'pubdate', order: 'DESC',
}],
{
unique: false,
name: 'feed_items_pubdate_index',
}
),
...
};
Resolved issue reference.
use uniqueKeys:
'use strict';
module.exports = {
up: (queryInterface, Sequelize) => {
return queryInterface.createTable('Users', {
id: {
allowNull: false,
autoIncrement: true,
