What are Sequelize model associations?
An example of an AI chatbot conversation about Sequelize model associations.
Can you explain what Sequelize model associations are?
Sequelize model associations define relationships between different models in a database, like one-to-one, one-to-many, and many-to-many.
How do I set up a one-to-many association in Sequelize?
To set up a one-to-many association, you can use the hasMany and belongsTo methods. For example, if you have a User and Post model, you would do: User.hasMany(Post) and Post.belongsTo(User).
Can you give me an example of a many-to-many association?
Sure! For a many-to-many association, you would typically use a junction table. For instance, if you have Student and Course models, you can create a StudentCourse model to link them.
What are the benefits of using associations in Sequelize?
Using associations helps to simplify queries, maintain data integrity, and allows for easier navigation between related data.
