How to create a model with Sequelize for Nodejs. It will create the tables, the indexes and auto generate and execute the queries directly for you.

• Sequelize Model Generate Primary Keys

I know the solution to this is often to set autoIncrement: true in the model definition. Generate Sequelize model definitions from a Swagger 2.0 schema - kingsquare/swagger-sequelize. One may need to mark 'x-primary-key': true in the model definition. Aug 22, 2015  If I define a custom primary key column for the table (instead of the default generated id column added when building the model with sequelize-cli model:create), the object passed back in the response has a null value for the primary key. Model Querying - Finders. Finder methods are the ones that generate SELECT queries. By default, the results of all finder methods are instances of the model class (as opposed to being just plain JavaScript objects). This means that after the database returns the results, Sequelize automatically wraps everything in proper instance objects. Sequelize also defines by default the fields id (primary key), createdAt and updatedAt to every model. This behavior can also be changed, of course (check the API Reference to learn more about the available options). Changing the default model options. Sequelize Model A sequelize model represents a table in the database. Instances of this class represent a database row. If you're not familiar with a relational database such as SQL, think excel. A relational database is a table of rows and columns. Sequalize helps manage that table, offering synchronization, association, validation.

Prequisites:

• Create a description of your REST service in a JSON format (see http://swagger.io/)
• Create your app and install (see http://docs.sequelizejs.com/en/latest/)

Currently, the project simply maps Swagger-datatypes to their Sequelize counterpart.

Sample usage:

In case you want to read from a swagger.yaml rather than from a swagger.json, you could replace the JSON-import

with a YAML-import

To be consistent, one should 'officially' add js-yaml to the project:

Primary key

To make your primary key work in Sequelize one may need to mark 'x-primary-key': true in the model definition in swagger.json: /rocket-league-key-generator-with-no-human-verivatcation.html.

And in swagger.yaml, it would be:

Additional parametrization

In the same way as with x-primary-key, you can parameterize the attributes x-autoincrement, x-unique and x-allow-null

Default value for UUID fields

It is possible to set default values for fields with uuid format
