Examples

// Get a post object and then update its title in the database
post = model("post").findByKey(33);
post.update(title="New version of Wheels just released");

// Get a post object and then update its title and other properties based on what is pased in from the URL/form
post = model("post").findByKey(params.key);
post.update(title="New version of Wheels just released", properties=params.post);

// If you have a `hasOne` association setup from `author` to `bio`, you can do a scoped call. (The `setBio` method below will call `bio.update(authorId=anAuthor.id)` internally.)
author = model("author").findByKey(params.authorId); 
bio = model("bio").findByKey(params.bioId); 
author.setBio(bio); 

// If you have a `hasMany` association setup from `owner` to `car`, you can do a scoped call. (The `addCar` method below will call `car.update(ownerId=anOwner.id)` internally.)
anOwner = model("owner").findByKey(params.ownerId); 
aCar = model("car").findByKey(params.carId); 
anOwner.addCar(aCar); 

// If you have a `hasMany` association setup from `post` to `comment`, you can do a scoped call. (The `removeComment` method below will call `comment.update(postId="")` internally.)
aPost = model("post").findByKey(params.postId); 
aComment = model("comment").findByKey(params.commentId); 
aPost.removeComment(aComment); // Get an object, and toggle a boolean property
user = model("user").findByKey(58); 
isSuccess = user.toggle("isActive"); // returns whether the object was saved properly

// You can also use a dynamic helper for this
isSuccess = user.toggleIsActive();
