How do I define relations in Sequelize?
An example of an AI chatbot conversation about defining relations in Sequelize ORM.
How do I define relations in Sequelize?
In Sequelize, you can define relations using methods like hasMany, belongsTo, belongsToMany, etc. Which relation are you interested in?
I want to set up a one-to-many relationship.
For a one-to-many relationship, you would use hasMany on the parent model and belongsTo on the child model. Can you provide the model names?
Sure, I have a User model and a Post model.
You can define it like this: User.hasMany(Post); and Post.belongsTo(User);. This sets up the relationship correctly.
What if I want to include additional fields in the relationship?
You can use a join table with belongsToMany and define additional fields in that table. Would you like an example?
