问题 Let us say there are two tables namely User and User Role. The relationship between user and user role is one to many. Sequelize model for the user is as following - const user = sequelize.define( 'user', { id: { type: DataTypes.BIGINT, allowNull: false, primaryKey: true, autoIncrement: true, field: 'id' }, userName: { type: DataTypes.STRING(200), allowNull: false, field: 'username' }, password: { type: DataTypes.STRING(200), allowNull: false, field: 'password' } }, { tableName: 'user' } );

问题 I can't seem to find the answer to this anywhere. I understand how Sequelize migrations and seeder work, but I have not found anywhere that states if they execute in some particular order. So if I start with a database, make a bunch of migrations, and then decide to initialize a brand new database from the original start point, will it execute the migrations in the exact same order. I am using sequelize-cli to create migrations, so the file name does begin with a timestamp. 回答1: For anyone

问题 I'm getting below error on expressJs with Sequelize DeprecationWarning: A boolean value was passed to options.operatorsAliases. This is a no-op with v5 and should be removed. Any idea to fix this? 回答1: This is not an error, it's simply a warning stating that passing boolean values to operatorsAliases in sequelize options will be deprecated in v5. To remove the warning, replace the boolean value by '1' or '0' for true and false respectively. 回答2: Package versions: "sequelize": "^5.21.3",

问题 I'm trying to get my nodejs application up and running using a docker container. I have no clue what might be wrong. The credentials seems to be passed correctly when I debug the credentials with the console. Also firing up sequel pro and connecting directly with the same username and password seems to work. When node starts in the container I get the error message: SequelizeConnectionRefusedError: connect ECONNREFUSED 127.0.0.1:3306 The application itself is loading correctly on port 3000,

问题 The migration selects data from one table and inserts the data into another table. While inserting, the sequelize adds backslash escape in varchar 'v_occupation' value which is throwing error in insertion. I have tried replacements and replace on v_occuption but all in vain const queryToUpdateExistingTable = `INSERT INTO social_profile ( fk_user_id , fk_marital_status_id ,fk_military_service_id , v_occupation , fk_education_id , v_bio ,v_pets ,v_places_lived ) VALUES (:fk_user_id , :fk
