如何选择 mongoose 的系列？

Question

How do i select which collection i want to access with mongoose? I have only used the normal mongo db before. Before i just did mongo.collection.something()

But on mongoose that don't work. I have tried to look at theirs docs but it not clear how to choose the collection, i have also tried to do mongoose.collection, but that don't work either. It should be simply to just choose what collection you want to use.

Anyone that can tell me how i access the collection of the database?

You need to mention schema before you perform any operation on collection using mongoose. Create schema as below:

// define a schema
var animalSchema = new Schema({ name: String, type: String });
var Animal = mongoose.model('Animal', animalSchema);

After this you can perform query operations as mentioned here: https://mongoosejs.com/docs/guide.html#query-helpers https://mongoosejs.com/docs/queries.html

To save or update follow save method from above mentioned document.

Make sure you follow same version as current mongoose version is 5.7.2
