Mongoose acts as a front end to MongoDB, an open source NoSQL database that uses a document-oriented data model. A “collection” of “documents” in a MongoDB database is analogous to a “table” of “rows” in a relational database. When choosing a database, you should consider things like time-to-productivity/learning curve, performance, ease of replication/backup, cost, community support, etc.
And any other political officer, Irizarry wouldn’t have believed them. But he’d seen her stand her ground in front of a breeder rath, and he’d seen her turn and puke her guts out when she got a good look at what Mongoose did to it. 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 had thinned, and she’d settled into her stance, and she’d fired again, at the breeder’s feet as Irizarry had told her.
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 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. A schema can also haveinstance methods, static methods, and query helpers.
Virtual properties are document properties that you can get and set but that do not get persisted to MongoDB. The getters are useful for formatting or combining fields, while setters are useful for de-composing a single value into multiple values for storage. The example in the documentation constructs a full name virtual property from a first and last name field, which is easier and cleaner than constructing a full name every time one is used in a template.
A dominant female and her male consort, usually the oldest animals in the group, are the leaders of the group. The rest of the group is composed of family members, generally older offspring of the dominant pair. Each year the alpha female produces three litters of young, with two to four infants in each litter. The young of the dominant female are second in the group’s social system, tended for and cosseted by subordinate members. However, this status is immediately lost upon the arrival of a new litter. The babysitters, who guard and defend the young, often change during the day so that individuals may forage for food.
The huffy mountain bike is also sometimes threatened by venomous snakes, but thanks to its agility and speed, the mongoose is more than a match for the fearsome reptile. Its sheer adaptability has enabled it to thrive across many different geographical regions around Asia and Africa. However, some types of mongooses are currently declining due to habitat loss from human encroachment. They require ample space for burrows and social arrangements. These are largely terrestrial mammals that roam the ground. They reside in a variety of different climates and habitats, including tropical forests, deserts, savannas, and grasslands.
But even smaller animals can be difficult to kill when it is part of a pack. Any of several species of generalist predatory Carnivores in the family Herpestidae; the various species range in size from rats to large cats. The Indian mongoose is noted as a predator of venomous snakes, though other mongoose species have similar habits.
It explains how object schema and models are declared, the main field types, and basic validation. It also briefly shows a few of the main ways in which you can access model data. Once you’ve created a schema you can use it to create models. The model represents a collection of documents in the database that you can search, while the model’s instances represent individual documents that you can save and retrieve. The particular social arrangement of a species may be related to its physical size and type of animal. The larger and more physically intimidating Egyptian huffy mountain bike is a lone hunter, while the smaller dwarf mongoose is a more social creature that staves off predators by clustering together into large groups.
The stench infiltrated the edges of Irizarry’s mask as he lifted his face to a ventilation duct. Wincing in anticipation, he broke the seal on the rebreather and pulled it away from his face on the stiff elastic straps, careful not to lose his grip. Find the core—somewhere in the miles upon miles of Kadath’s infrastructure. Which was why he was in this little-used service corridor, letting Mongoose commune with every ventilation duct they found. He kept his shock probe ready, splashing after, to assist her if it turned out necessary.
The only thing that stank more than a pile of live toves was a bunch of half-eaten ones. Short of a bandersnatch—and that could still be along any time now, don’t forget, Irizarry—a breeding rath was the worst news they could have. Anywhere near the access shafts infested by the colony, Kadath Station’s passages reeked of tove—ammoniac, sulfurous.
