In a sails project, considering a model User and a model Role, with a relationship between User and Role :
// `User.js
module.exports = {
attributes: {
...
roles: {
collection: 'role',
dominant: true
},
...
}
}
For the the database representation, sails/waterline will create following tables :
user_roles__role_roles_role to represent the collectionI know we can force the name for the models USER and ROLE (with the property 'tablename' : http://sailsjs.com/documentation/concepts/models-and-orm/attributes).
But how can we force the name the relationship table ? (Especially this name is quite long and tends to exceed limit).
Assuming this is a two-way relationship, and the Role model has a users collection, Sails will expect a table named role_users__user_roles, which has the role id first, user id second.
Your example table name would require User to be dominant and would require the Role model to have an attribute named roles_role that is a User collection.
To create your own join table, you can use the through association method and add a new model that represents the relationship, perhaps UsersRoles, and specify the tableName in that model definition.
Examples of the through association:
