Models - Access a Model

Any callback in the application that is passed the request object can access the Models programmatically. If the actions property in the model definition is set, some of the methods cannot be invoked. The actions property restricts which CRUD operations can be invoked on the models.

Retrieve an instance to API Builder using the request.server property.
Retrieve the Model instance using API Builder's getModel('name') method by passing it the name of the model.
Invoke one of the following methods on the Model instance and pass it a callback function, which is passed an error and results object:
- create(object, callback): Creates a model
- query(options, callback): Retrieves models specified by the query
- findAll(callback): Retrieves all models
- findById(id, callback): Retrieves the model specified by the id parameter
- update(instance, callback): Updates the passed model
- deleteAll(callback): Deletes all models
- delete(instance, callback): Deletes the passed model

Example:

The Route example below retrieves all car model.

web/routes/testroute.js

                      
                      
                        
                            var Arrow = require('arrow');
 
var TestRoute = Arrow.Router.extend({
    name: 'car',
    path: '/car',
    method: 'GET',
    description: 'get some cars',
    action: function (req, res, next) {
        var model = req.server.getModel('car');
        model.findAll(function(err, results){
            if (err) {
                next(err);
            } else {
                req.log.info('got cars ' + JSON.stringify(results));
                res.render('car', {cars:results});
            }
 
        });
    }
});
 
module.exports = TestRoute;
