I'm just a beginner, I got this error when I set up the association table, I don't know why

[cuilonglong0422]

association.init is not a function




I hope you can help me see it when you have time, I don't want to use the basic methods in the sequelize documentation, it will look very unprofessional

[cuilonglong0422]

this is my source code
// class user
