'Include' in Sequelize: The One Confusing Query That You Should Memorize

When querying your database in Sequelize, you'll often want data associated with a particular model which isn't in the model's table directly. This data is usually typically associated through join tables (e.g. a 'hasMany' or 'belongsToMany' association), or a foreign key (e.g. a 'hasOne' or 'belongsTo' association).

When you query, you'll receive just the rows you've looked for. With eager loading, you'll also get any associated data. For some reason, I can never remember the proper way to do eager loading when writing my Sequelize queries. I've seen others struggle with the same thing.

Eager loading is confusing because the 'include' that is uses has unfamiliar fields is set in an array rather than just an object.

So let's go through the one query that's worth memorizing to handle your eager loading.

The Basic Query

		it('is a nested spec', () => true);
	});

When npm installs native node modules it uses node-gyp to compile code. This is the seam node uses for targeting different operating systems, e.g. OS X, linux, Windows etc.

By default node-gyp compiles using one core and if you have more than one you probably want to utilize that power to speed up compile time. The way node-gyp handles this is by using the JOBS environment variable, which sets the jobs variable here. This piece of code then checks the value of jobs to determine how many cores to use.

Note that if the value of JOBS is max then all cores will be used. So lets try this on leveldown. First lets check that JOBS isn't set yet:

lms@ux301|01:34|~/src/leveldb-repos/leveldown (master) $ echo $JOBS

Usage - This hook prevents a dev from committing code without having a reference to a tfs work item

Installation. Create a folder in your project root called githooks and save the commit-msg file in there.

The githook can then be installed by symlinking them to your .git/hooks dir.

Run these commands from the project root

$ ln -s ../../githooks/pre-commit .git/hooks/
$ ln -s ../../githooks/commit-msg .git/hooks/
