Many To Many Association Fetch Not Working #3185
Description
I am using a many to many association between a user and a group and I got the following error when I want to fetch the groups associated to a user :
Possibly unhandled SequelizeDatabaseError: la colonne User_has_Group.GroupIdGroup n'existe pas

Environment :

Here is the code :
User model
var User = sequelize.define('User', {
'iduser': {
type: DataTypes.UUID,
primaryKey: true,
defaultValue: DataTypes.UUIDV4,
allowNull: false
},
....
}, {
tableName: 'User',
paranoid: true,
// Timestamps
timestamps: true,
createdAt: 'created_at',
updatedAt: false,
deletedAt: 'deleted_at',
// Methods
classMethods: {
associate: function(models) {
User.belongsToMany(models.Group, {as:'groups', through: models.User_has_Group, foreignKey: 'id_user'});
}
}
});Group Model
var Group = sequelize.define('Group', {
'id_group': {
type: DataTypes.UUID,
allowNull: false,
primaryKey: true,
defaultValue: DataTypes.UUIDV4
},
....
}, {
tableName: 'Group',
paranoid: true,
// Timestamps
timestamps: true,
createdAt: 'created_at',
updatedAt: false,
deletedAt: 'deleted_at',
// Methods
classMethods: {
associate: function(models) {
Group.belongsToMany(models.User, {as: 'users', through: models.User_has_Group, foreignKey: 'id_group'});
}
}
});User_has_Group Model
var User_has_Group = sequelize.define('User_has_Group', {
...
}, {
tableName: 'User_has_Group',
paranoid: false,
// Timestamps
timestamps: true,
createdAt: 'created_at',
updatedAt: 'updated_at',
deletedAt: 'deleted_at'
});The code that crash
on the line _user.getGroups().then(function(groups) {_
Models.User.find({
where: {
id_user: request.params.id_user
}
})
.then(function(user) {
...
user.getGroups().then(function(groups) {
})
}
})Thanks for the help
