Do you know where the .createPost method from line 31 is defined? I could understand a .create method, but .createPost seems oddly specific.

@yejodido I would also like to know the answer for that. I know that createPost is dynamically generated by sequelize, but I don't know what the generic equivalent is

would also like to know

so createPost comes from the AuthorModel.hasMany(PostModel);. Here is the documentation: http://docs.sequelizejs.com/en/latest/api/associations/belongs-to/

Sequelize autocamelcases post from db.define('post'.... which createPost is a reference too. Be aware of plural and non-plural when using sequelize, because it does make a difference on how you data is added/removed from the database.
