It also briefly shows a few of the main ways in which you can access model data. You can create references from one document/model instance to another using the ObjectId schema field, or from one document to many using an array of ObjectIds. If schwinn bicycles you need the actual content of the associated document, you can use the populate() method in a query to replace the id with the actual data. You can search for records using query methods, specifying the query conditions as a JSON document.
Each schwinn bicycles model keeps a reference to a native MongoDB driver collection. The collection object can be accessed using YourModel.collection. However, using the collection object directly bypasses all mongoose features, including hooks, validation, etc.
Our story document now has an author referenced by the author document’s ID. In order to get the author information in the story results we use populate(), as shown below. Creation of records are asynchronous operations — you supply a callback that is called when the operation completes.
Unlike the boojum-ships they serviced, the stations—Providence, Kadath, Leng, Dunwich, and the others—were man-made. Their radial symmetry was predictable, and to find the station master, Irizarry only had to work his way inward from the Manfred von Richthofen’s dock to the hub. Mongoose copied him, tilting her head first one way, then another, though flat representations meant nothing to her. He made out STATION MASTER’S OFFICE finally, on a oval bubble, the door of which was actually in sight.
The code fragment below shows how you might find all athletes in a database that play tennis, returning just the fields for athlete name and age. Here we just specify one matching field but you can add more criteria, specify regular expression criteria, or remove the conditions altogether to return all athletes. The code fragment below shows how you might define a simple schema. First you require() mongoose, then use the Schema constructor to create a new schema instance, defining the various fields inside it in the constructor’s object parameter. You can also use create() to define the model instance at the same time as you save it.
At the zoo we care for a pair of lemurs, Felipe and Alana. We feed the lemurs a high-fiber leaf-eater biscuit along with apples, yams, grapes, zucchini, and spinach and other greens. The lemurs’ favorite enrichment items include puzzle feeders, toys, new vines, play pieces to climb on, and interactive digital media such as electronic tablets!
