However, what if the table actually doesn't even exist in the database? What if it exists, but it has different columns, less columns, or any other difference? When you define a model, you're telling Sequelize a few things about its table in the database. After being defined, we can access our model with. We want our model to be called User, and the table it represents is called Users in the database.īoth ways to define this model are shown below. To learn with an example, we will consider that we want to create a model to represent users, which have a firstName and a lastName.
Usually, models have singular names (such as User) while tables have pluralized names (such as Users), although this is fully configurable. This name does not have to be the same name of the table it represents in the database. The model tells Sequelize several things about the entity it represents, such as the name of the table in the database and which columns it has (and their data types).Ī model in Sequelize has a name. In Sequelize, it is a class that extends Model.
A model is an abstraction that represents a table in your database. In this tutorial you will learn what models are in Sequelize and how to use them.
