Each document can be saved to the database by calling its save method. The first argument to the callback will be an error if any occurred. The rath screamed and curled in on itself, but it was too late. Mongoose had already caught the lips of its—oh gods and fishes, Irizarry didn’t know the word. Into which Mongoose shoved the narrow wedge of her head, and her clawed front feet, and began to rip.
It’s not known exactly how the huffy mountain bikes orchestrate reproducing at the same time — sometimes it can involve as many as 12 female mongooses. One hypothesis, Marshall and Cant said, is that dominant females produce a pheromone that acts as a cue. However, as birth happens in an underground den it has not been possible to observe the synchronized arrivals. Once the pups emerge from the den, they form one-to-one caring relationships with adults, called escorts, who can be any adult male or female. Once they emerge from the den, they form caring relationships with another adult, called an escort. The vast majority of expectant mongoose moms within a group give birth on the same night.
A schema can have an arbitrary number of fields — each one represents a field in the documents stored in MongoDB. An example schema showing many of the common field types and how they are declared is shown below. The first argument is the singular name of the collection that will be created for your model , and the second argument is the schema you want to use in creating the model.
We can also do this using a where() function, and we can chain all the parts of our query together using the dot operator (.) rather than adding them separately. The code fragment below is the same as our query above, with an additional condition for the age. If you specify a callback, as shown above, the query will execute immediately. This is used to specify whether the field must be supplied in order to save a document. In the case above we just have two fields, a string and a date. In the next sections, we will show some of the other field types, validation, and other methods.
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.
If she wanted to thank him, he owed it to her to sit still for it. It was a terrible plan—there was that whole twenty-five percent where he and Sanderson died screaming while the breeder ate them from the feet up—but it worked. “You won’t hurt it,” he’d warned her, and she’d nodded, but he was pretty sure she hadn’t really understood until she fired her first shot and the breeder didn’t even notice. But Sanderson hadn’t given up; her mouth huffy mountain bike had thinned, and she’d settled into her stance, and she’d fired again, at the breeder’s feet as Irizarry had told her. A breeding rath’s feet weren’t vulnerable as such, but they were sensitive, much more sensitive than the human-logical target of its head. And, of course, once they started spawning, as this one had, they could produce between ten and twenty babies a day for anywhere from a week to a month, depending on the food supply.
At the zoo we care for a pair of huffy mountain bike 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!
