Auto updating pivot table

This can be done with the model's object must be passed along in the options of any relevant Bookshelf calls, to ensure all queries are on the same connection.The entire transaction block is a promise that will resolve when the transaction is committed, or fail if the transaction is rolled back.

Also note that you will have to create the appropriate database(s) for the test suite to run.

Bookshelf is a Java Script ORM for Node.js, built on the Knex SQL query builder.

Featuring both promise based and traditional callback interfaces, providing transaction support, eager/nested-eager relation loading, polymorphic associations, and support for one-to-one, one-to-many, and many-to-many relations.

Yes - you can call - notice that the id is a string in one case and a number in the other.

This can be a common mistake if retrieving the id from a url parameter.

We found the following projects using Bookshelf, but there can be more: You sometimes need to manipulate data from the database into the correct types.

Maybe you have a TEXT field that is actually a comma separated list of tags, or a blob field with JSON that you want to parse.

For example, with My SQL, you'll need to run the command in addition to exporting the correct test settings prior to running the test suite.

While it primarily targets Node.js, all dependencies are browser compatible, and it could be adapted to work with other javascript environments supporting a sqlite3 database, by providing a custom Knex adapter.

This is only an issue if you're eager loading data with load without first fetching the original model. The issue here is that Knex, the database abstraction layer used by Bookshelf, uses connection pooling and thus keeps the database connection open.

If you want your process to exit after your script has finished, you will have to call as one of the options in your initialize settings, you can see all of the query calls being made.

A common pattern to follow is to initialize the client in a module so you can easily reference it later: // In a file named something like var knex = require('knex')(db Config); module.exports = require('bookshelf')(knex); // elsewhere, to use the bookshelf client: var bookshelf = require('./bookshelf'); var Post = bookshelf. Model.extend() User.where('id', 1).fetch().then(function(user) ).catch(function(err) ); Have questions about the library?
