hasMany: destroyAssociations

Hello,

I’m trying to figure out if there is a way to remove associations from table instead of setting foreign key to null when i call setAssociations(null). For example, if i have Author and Post models:

const Author = Sequelize.define('author', {
  name: Sequelize.STRING
});

const Post = Sequelize.define('post', {
  title: Sequelize.STRING
});

Author.hasMany(Post);
Post.belongsTo(Author);

And i want to remove all posts for this author, I would like to use something like this:

const author = Author.findById(1);
author.setPosts([]).then(() => ...);

But the problem is that this just sets authorId to NULL in posts table. How can i literally remove it from the table?

Thanks.
