Explain, please.

Installation

var mySchema = new mongoose.Schema({...});
var crudibility = require('crudibility');
mySchema.plugin(crudibility);

Methods

add

Signature

add(attributes, [options], callback)

• attributes - hash of attributes to put in the document
• options (optional)
  • fields - see defaultFields section for details
  • populate - see crudiblePopulate section for details
• callback - called with (err, document)

Example

mongoose.models.Foo.add(
  {
    foo: 'bar'
  },
  {
    fields: 'foo',
    populate: [{
      path: 'baz'
    }]
  }, function (err, doc) {
    // a new document { foo: 'bar' } should now be in the database
  }
);

edit

Signature

edit(attributes, [options], callback)

• attributes - hash of attributes to set on the document, will only change attributes explicitly mentioned and leave old ones
  • must include an _id of the document to edit
• options (optional)
  • fields - see fields section for details
  • populate - see populate section for details
• callback - called with (err, document)

Example

mongoose.models.Foo.edit(
  {
    _id: '000000000000000000000001',
    foo: 'bar'
  },
  {
    fields: 'foo',
    populate: [{
      path: 'baz'
    }]
  }, function (err, doc) {
    // ...
  }
);

view

Signature

view(params, callback)

• params
  • _id - can use _id to retrieve a specific document
  • match - alternative to _id, can enter matching parameters (e.g. {foo: 'bar'} to retrieve the first document with field foo matching 'bar')
  • fields - see fields section for details
  • populate - see populate section for details
• callback - called with (err, document)

Example

mongoose.models.Foo.view(
  {
    _id: '000000000000000000000001',
    fields: 'foo',
    populate: [{
      path: 'baz'
    }]
  }, function (err, doc) {
    // ...
  }
);

list

Signature

list(params, callback)

• params
  • match - can enter matching parameters (e.g. {foo: 'bar'} to retrieve documents with field foo matching 'bar')
  • fields - see fields section for details
  • sort - takes the same options as Mongoose's sort option
  • populate - see populate section for details
  • paginate - see paginate section for details
• callback - called with (err, documents, meta)
  • meta - returns metadata for use with the Backbone Paginator plugin - currentPage, totalPages, pageSize, and totalResults

Example

mongoose.models.Foo.list(
  {
    match:
      foo: 'bar'
    fields: 'foo',
    populate: [{
      path: 'baz'
    }]
  }, function (err, docs, meta) {
    // ...
  }
);

delete

Signature

delete(params, callback)

• params
  • _id - use _id to delete a specific document
• callback - calls back with (err, document). The document will not be populated as with other methods.

Example

mongoose.models.Foo.delete(
  {
    _id: '000000000000000000000001'
  }, function (err, doc) {
    // doc's all gone from the database now!
  }
);

Options

Setting Defaults

When installing the plugin, you can define default options for the model as follows:

var crudibility = require('crudibility');
mySchema.plugin(crudibility, {
  defaultFields: 'foo', // see fields section below for details
  defaultPopulate: [],  // see populate below for details
  defaultPaginate: {}   // see paginate below for details
});

fields

fields options follow the same convention as Mongoose's select.

populate

Crudibility allows for nested populates. Nested populates should be nested within their parent populate. For example:

{
  populate: [
    path: 'baz',    // will populate the document at path 'baz'
    model: 'Baz',   // will populate from the Baz model (this is required!)
    select: 'qux',  // will populate from the Baz model with field 'qux'
    populate: [
      path: 'baz.qux',  // second-level populate, since it depends on 'baz' being populated first
      model: 'Qux',
      select: 'foo'
    ]
  ]
}

paginate

Paginate options determine which page and how many documents per page will be returned for a list function.

There are aliases for the same functionality - two examples representing the same options are shown below:

{
  paginate: {
    limit: 2,    // 2 documents per page
    page: 2      // return the third page (pages are zero-indexed)
  }
}

{
  paginate: {
    pageSize: 2,
    currentPage: 2
  }
}
