I'm new to mongoose and i have a problem.
In my app, i have a Travel model like this:
const travelSchema = new mongoose.Schema({
title: {
type: String,
required: [true, 'Please add a title'],
trim: true,
maxlength: [50, 'Title can not be more than 50 characters'],
},
cities: [
{
type: mongoose.Schema.Types.ObjectId,
ref: 'City',
},
],
});
and a City model like this :
const citySchema = new mongoose.Schema({
name: {
type: String,
required: true,
trim: true,
},
location: {
type: {
type: String,
enum: ['Point'],
required: true,
},
coordinates: {
type: [Number],
required: true,
},
},
travels: [
{
type: mongoose.Schema.Types.ObjectId,
ref: 'Travel',
},
],
});
So when i delete a travel, i want to remove the travel_id from the 'travels' field of the cities which are concerned by the travel.
Here i am:
exports.deleteTravel = asyncHandler(async (req, res, next) => {
const travel = await Travel.findByIdAndDelete(req.params.id);
travel.cities.map(cityId => {
City.findByIdAndUpdate(
cityId,
{ travels: travels.filter(id => id !== travel._id) },
{
new: true,
runValidators: true,
}
);
});
res.status(200).json({ success: true, data: {} });
});
I got this error message: Error: travels is not defined
Do you have any idea why?
Many thanks !
It's working like this :)
exports.deleteTravel = asyncHandler(async (req, res, next) => {
const travel = await Travel.findByIdAndDelete(req.params.id);
travel.cities.map(async cityId => {
await City.findByIdAndUpdate(
cityId,
{ $pull: { travels: travel._id } },
{
new: true,
runValidators: true,
}
);
});

While trying to save data into postgres database using sequelize BlogModel.create() system failed to save the data into table and server is returning columns createdat, updatedat, multiple times in console. ( please see below ). In the scheme I have added the column only once, can someone advise on this issue here ?
Executing (default): INSERT INTO "userBlogs" ("id","email","blogdetails","tags","createdat","updatedat","createdAt","updatedAt") VALUES (DEFAULT,$1,$2,$3,$4,$5,$6,$7) RETURNING "id","email","blogdetails","tags","createdat","updatedat","createdAt","updatedAt";
//userBlogs.js
'use strict';
module.exports = (sequelize, DataTypes) => {
const userBlogs = sequelize.define('userBlogs', {
id: {
type: DataTypes.INTEGER(10),
allowNull: false,
primaryKey: true,
autoIncrement: true
},
email: {
type: DataTypes.STRING(255),
allowNull: false
},
blogdetails: {
type: DataTypes.TEXT,
allowNull: false
},
tags: {
type: DataTypes.STRING(255),
allowNull: false
},
createdat: {
type: DataTypes.DATE,
allowNull: false,
defaultValue: DataTypes.NOW
},
updatedat: {
type: DataTypes.DATE,

}
}, {

});
return userBlogs;
};
//server.js
const usersBlogSchema = require('./modals/userBlogs');
const BlogModel = usersBlogSchema(sequelize, DataTypes);
app.post('/service/createblogs', async (req, res, next)=> {
try {
const userEmail = req.body.email;
const blogDetails = req.body.blogValue;
const tags = req.body.tagValue;
if (Object.keys(req.body).length === 0) {
res.status(403).json({ fail: "Invalid blog request or blog request is blank !" });
} else {
var requestData = {email:userEmail, blogdetails:blogDetails, tags:tags };
const createBlogRequest = await BlogModel.create(requestData);
res.status(200).json({ success: true });
}
} catch (e) {
console.log(e)
return next(e);
}
});
Returning createdAt and updatedAt multiple times because you have added columns (createdAt and updatedAt )and also timestamps:true ,
timestamps also adds these both columns
use either columns or timestamps
'use strict';
module.exports = (sequelize, DataTypes) => {
const userBlogs = sequelize.define('userBlogs', {
id: {
type: DataTypes.INTEGER(10),
allowNull: false,
primaryKey: true,
autoIncrement: true
},
email: {
type: DataTypes.STRING(255),
allowNull: false
},
blogdetails: {
type: DataTypes.TEXT,
allowNull: false
},
tags: {
type: DataTypes.STRING(255),
allowNull: false
},
}, {
timestamps: true,
tableName: 'userBlogs'
});
return userBlogs;
};
i am using PostgreSQL with Sequelize ORM to create my db.
I have this models:
models.js
const Users = db.define("users", {
name: {
type: DataTypes.STRING,
},
lastname: {
type: DataTypes.STRING,
},
sector: {
type: DataTypes.STRING,
},
email: { type: DataTypes.STRING, unique: true, allowNull: false },
password: { type: DataTypes.STRING, allowNull: false },
points: { type: DataTypes.INTEGER, defaultValue: 0 },
suscripcion: { type: DataTypes.BOOLEAN, defaultValue: false },
preference_id: { type: DataTypes.STRING },
});
const Pronostico = db.define("pronosticos", {
matchId: {
type: DataTypes.STRING,
unique: true,
},
winner: {
type: DataTypes.STRING,
},
goalHome: {
type: DataTypes.INTEGER,
},
goalAway: {
type: DataTypes.INTEGER,
},
});
//REFRESH TOKEN
const RefreshToken = db.define("refreshTokens", {
token: {
type: DataTypes.STRING,
},
expiryDate: {
type: DataTypes.DATE,
},
userId: {
type: DataTypes.STRING,
},
});
RefreshToken.createToken = async function (user) {
let expiredAt = new Date();
expiredAt.setSeconds(expiredAt.getSeconds() + config.jwtRefreshExpiration);
let _token = uuidv4();
let refreshToken = await this.create({
token: _token,
userId: user.id,
expiryDate: expiredAt.getTime(),
});
return refreshToken.token;
};
RefreshToken.verifyExpiration = (token) => {
return token.expiryDate.getTime() < new Date().getTime();
};
This are the Relationships:
Users.hasMany(Pronostico, { as: "pronosticos" });
Pronostico.belongsTo(Users, { foreignKey: "userId", as: "user" });
RefreshToken.belongsTo(User, {
foreignKey: 'userId', targetKey: 'id'
});
User.hasOne(RefreshToken, {
foreignKey: 'userId', targetKey: 'id'
});
Somewhere on my server, I have this controller which creates a refreshToken:
let refreshToken = await RefreshToken.createToken(user);
The problem is that I get an error that says "column userId doesnt exist in refreshTokens relationship.
Maybe I have some issues with the relationships but I think they are OK.
Any suggestion?
I'm new to sequelize as a user and I use the 'many to many' option in the team situation. I created my code but : user_team is not associated to team! i am getting error how can i fix it. I'm doing it for a task, I would be very happy if you help me.tanks
If the structure is also wrong, can you tell me what my mistakes are?
userteam.js
module.exports = (sequelize, DataTypes) => {
const UserTeam = sequelize.define(

{
user_team_id: {
type: DataTypes.INTEGER,

as: "Team",
});
};
return UserTeam;
};
user.js
module.exports = (sequelize, DataTypes) => {
const User = sequelize.define(

});
Team.belongsToMany(models.User, {
as: "UserInTeam",
through: models.UserTeam,
foreignKey: "team_id",
});
};
return Team;
};
controller.js
const getAll = async (req, res, next) => {
try {
const myTeams = await Team.findAll({
include: [{ model: UserTeam }],
});
myTeams.forEach((element) => {
console.log(element.get());
});
return res.status(200).json(myTeams);
} catch (err) {
console.log(err.message);
res.status(500).json({ message: err });
}
};
i solved this problem
just add to index database config js
db.users.belongsToMany(db.team, {
as: "teams",
through: "user_team",
foreignKey: "user_id",
});
db.team.belongsToMany(db.users, {
as: "users",
through: "user_team",
foreignKey: "team_id",
});
enter code here
I'm building one of my first admin areas for a site in React. I'm using mongoose and MongoDB. When I submit the form to add an artist to the db it does everything correctly and I can see it return the data as a JSON Object. When I submit a form that adds a piece of artwork to an artist it looks like it works but it actually does not add anything to the database as the data is sent as a string. I believe the only difference is one route is a POST and one is a Patch. I can't find any other difference. How can I make my form send data as a JSON instead of a string.
My Model
const mongoose = require("mongoose");
const Schema = mongoose.Schema;
const artistSchema = new Schema({
first_name: { type: String, required: true },
last_name: { type: String, required: true },
artist_painter: { type: Boolean, required: false},
artist_sculptor: { type: Boolean, required: false},
artist_other: { type: Boolean, required: false},
featured_image: { type: String, required: false},
artwork:[
{
type: { type: String, required: false},
title: { type: String, required: false},
width: { type: Number, required: false},
length: { type: Number, required: false},
depth: { type: Number, required: false},
image: { type: String, required: false},
media: { type: String, required: false},
price: { type: Number, required: false},
newRelease: { type: Boolean, required: false}
}
]
});
const Artist = mongoose.model("Artist", artistSchema);
module.exports = Artist

I want to increase the score of a player by updating it. Here is the call.
const addPlayerScore = async (score, currentPlayer) => {
try {
const addScore = {
score: score,
};
const { data } = await fetchContext.authAxios.patch(
`/facilitator/add-score-player-team-one/${currentPlayer}`,
addScore
);
console.log(data.message);
} catch (error) {
const { data } = error.response;
console.log(data.message);
}
};
the currentPlayer takes the id of player. Which I passed into the params.
here is the request;
exports.addscoreplayerteamone = async (req, res) => {
try {
const { score } = req.body;
const existLive = await LiveMatch.findOneAndUpdate(
{
'teamOne.players._id': req.params.id,
},
{
$set: {
$inc: {
'teamOne.players.$.scores': score,
},
},
},
{ new: true }
);
const addPlayerScore = await existLive.save();
res
.status(200)
.send({ message: "Added the player's score", addPlayerScore });
} catch (error) {
console.log(error);
return res.status(400).json({
message: 'There was a problem adding a score',
});
}
};
here is the schema;
const mongoose = require('mongoose');
const liveSchema = new mongoose.Schema(
{
schedule: {
type: mongoose.Types.ObjectId,
required: true,
},
user: {
type: mongoose.Types.ObjectId,
required: true,

teamOne: {
teamName: {
type: String,
required: true,
trim: true,
max: 50,
},
players: [
{

type: String,
required: true,
trim: true,
max: 50,
},
jerseyNumber: {
type: String,
required: true,
trim: true,
},
scores: {
type: Number,
default: 0,
trim: true,
},

},
],
score: {
type: Number,
trim: true,

},
},

teamName: {

required: true,
trim: true,
max: 50,
},
players: [
{

type: String,
required: true,
trim: true,

},
jerseyNumber: {
type: String,
required: true,
trim: true,

scores: {
type: Number,
default: 0,
trim: true,
},
fouls: {
type: Number,
trim: true,
},
},
],
score: {
type: Number,
trim: true,
default: 0,
},
},
gameEvent: {
type: String,
required: true,
enum: ['basketball', 'volleyball', 'soccer'],
},
winner: {
type: String,
trim: true,
},
loser: {
type: String,
trim: true,
},
},
{ timestamps: true }
);
module.exports = mongoose.model('live-match', liveSchema);
it returns status 200 but it does not increments the score of the player in the database nor being reflected in the frontend.
Try this:
const existLive = await LiveMatch.findOneAndUpdate(
{
'teamOne.players._id': req.params.id,
},
{
$inc: { 'teamOne.players.scores': score }
},
{
new: true
}
);
