what is the relevance of first string parameter in mongoose.model method?

Question

while compiling a schema we use the mongoose.model, I am not able to understand the relevance of first String argument accepted by the model method

var Kitten = mongoose.model('Kitten', kittySchema);

Here the first argument inside model method is 'Kitten' and the second argument is the schema, can I give any name to the first argument?

its not clear in the docs http://mongoosejs.com/docs/api.html#model-js

Am I referring the correct docs?

Answer 1

We need to convert our Schema into a Model we can work with. To do so, we pass it into mongoose.model(modelName, schema):

so you can use any name that you want for modelName but it should be meaning full

also valid if you define userSchema as model name User or Customer like:

mongoose.model('User', userSchema); then table will be creat with name users

or

mongoose.model('Customer', userSchema); then table will be creat with name customers

see this document and this one

Answer 2

In your example:

var Kitten = mongoose.model('Kitten', kittySchema);

The difference between the variable name Kitten and the parameter string "Kitten" is that kitten refers to the model name, and "Kitten" refers to the collection name.

NOTE: mongodb will convert the string "Kitten" into a plural form, so you will find the collection named "Kittens" (with 's' at the end) inside your mongodb.
