Create Forms

Work with mongoose model. On your api, create a route 'metadata' for a given model :

// In your routes.js
const path = require('path');
const _MMetadata = require('mongoose-metadata');
const Metadata = _MMetadata(mongoose);


// Load Models
Metadata.loadModels(path.join(__dirname, './models'));

// Let's use a model pet
// We need to use the meta middleware : Metadata.meta('<modelName>')
app.get('/<modelName>/meta_add', Metadata.meta('<Model>'));

Filter fields

// First of all, import the module
const path = require('path');
const _MMetadata = require('mongoose-metadata');
const Metadata = _MMetadata(mongoose);

// Load Models
Metadata.loadModels(path.join(__dirname, './models'))

// Here, we remove the name field from the meta so it will not be rendered
// So, for those fields, you would not get a form input client side.
app.get('/<modelName>/meta_edit', Metadata.meta('<Model>', {
  filter: ['name']
}));
