Sequelize indexes option

If you create a foreign key constraint no further index will be auto created by postgres (I'm not sure what other DBs will do, I did not check), since there are a couple of different ways to create a index in that case.. But I'd say the average use case would be improved if sequelize would just add a normal btree index on the foreign key if you pass a option to the global sequelize instance. Support for specifying indexes on a model #2057. Merged janmeier merged 6 commits into master from indexes Jul 29, 2014. Merged Allow setting plural and singular name on the model (`options.name` in `sequelize.define`) and in associations (`options.as`) to circumvent issues with weird pluralization.-

Extra-options for creation. options: object: optional; query options. options.force: boolean: If force is true, any existing functions with the same parameters will be replaced. For postgres, this means using CREATE OR REPLACE FUNCTION instead of CREATE FUNCTION. Default is false. options.variables: Array < object > List of declared variables. Default Hooks (on Sequelize constructor options) Permanent Hooks (with sequelize.addHook) Connection Hooks; Instance hooks; Model hooks; Associations; One-to-One and One-to-Many associations; Many-to-Many associations; Hooks and Transactions; Internal Transactions If you create a foreign key constraint no further index will be auto created by postgres (I'm not sure what other DBs will do, I did not check), since there are a couple of different ways to create a index in that case..

This timezone is used when initializing a connection (using `SET TIME ZONE` or equivalent), and when converting a timestamp string from the DB to a JS date with mysql (postgres stores the timezone, so for postgres we rely on what's in the DB).

How to define unique index on multiple columns in sequelize. Ask Question Asked 2 years, When I use the unique indexes with sequelize I'm still able to create two rows with the same values in those columns. Didn't add the uniqueKeys option. underscored option. Sequelize allow setting underscored option for Model. When true this option will set the field option on all attributes to the underscored version of its name. This also applies to foreign keys generated by associations. Let's modify last example to use underscored option. I'm not sure we're talking about the same thing here, this issue was meant to reflect that when using the underscore option it doesn't work in the fields when setting indexes. Check the example, I would expect to be able to use fields: ['testField'] but I need to use fields: ['test_field'] .
