I've got the following tables:
books
book_reviews
users
Here are the models that correspond to said tables:
const BookReview = require('./BookReview').model;
const User = require('./User').model;
module.exports.model = bookshelf.Model.extend({
tableName: 'books',
user: function() {
return this.hasOne(User, 'user_id');
},
reviews: function() {
return this.hasMany(BookReview);
}
});
module.exports.model = bookshelf.Model.extend({
tableName: 'book_reviews',
user: function() {
this.hasMany(User, 'user_id');
}
});
module.exports.model = bookshelf.Model.extend({
tableName: 'users',
reviews: function() {
return this.belongsToMany(BookReview, 'user_id');
}
});
I'm looking up a Book and trying to fetch all reviews that it has, which it currently is doing with the following statement:
return Book.forge({
id: req.params.id,
type: req.params.type
}).fetch({withRelated: ['reviews'], require: true}).then(function(book) {
console.log(book.toJSON());
return book;
}).catch(function(err) {
throw new Error(err.message);
});
};
And the output from book.toJSON()
from above looks like:
Output from book.toJSON() from above:
{ id: 1,
type: 'novel',
slug: 'catcher-in-the-rye',
user_id: 1,
name: 'Catcher in the Rye',
created_at: Tue Oct 04 2016 22:35:42 GMT-0700 (PDT),
updated_at: Tue Oct 04 2016 22:35:42 GMT-0700 (PDT),
reviews:
[ { id: 14,
user_id: 2,
book_id: 1,
rating: 3,
review: 'Test',
created_at: Wed Oct 05 2016 20:47:34 GMT-0700 (PDT),
updated_at: Wed Oct 05 2016 20:47:34 GMT-0700 (PDT) } ] }
But my intent is that each of the reviews
would have a reference to the users
table, which they currently don't. How can I link those together?
What if you do:
return Book.forge({
id: req.params.id,
type: req.params.type
}).fetch({withRelated: ['reviews', 'reviews.user'], require: true}).then(function(book) {
console.log(book.toJSON());
return book;
}).catch(function(err) {
throw new Error(err.message);
});
