Frappe Core

Core libs for Frappe Framework JS

Declaring Models

Models are declared by adding a .json model file in the models/doctype folder of the module/app.

{
	"autoname": "hash",
	"name": "ToDo",
	"doctype": "DocType",
	"issingle": 0,
	"fields": [
		{
			"fieldname": "subject",
			"label": "Subject",
			"fieldtype": "Data",
			"reqd": 1
		},
		{
			"fieldname": "description",
			"label": "Description",
			"fieldtype": "Text"
		},
		{
			"fieldname": "status",
			"label": "Status",
			"fieldtype": "Select",
			"options": [
				"Open",
				"Closed"
			],
			"default": "Open",
			"reqd": 1
		}
	]
}

Setup / Migrate

const frappe = require('frappe-core');
frappe.init();

// sync all schema from `models` folders in all apps
frappe.migrate();

Managing Documents

Frappe Object-Relational-Mapper (ORM) helps you manage (create, read, update, delete) documents based on the DocTypes declared.

Documents are stored in SQLite using sql.js

Create

const frappe = require('frappe-core');
frappe.init();

// make a new todo
let todo = frappe.get_doc({doctype: 'ToDo', subject: 'something'});
todo.insert();

Read

const frappe = require('frappe-core');
frappe.init();

// get all open todos
let todos = frappe.db.get_all('ToDo', ['name'], {status: "Open"});
let first_todo = frappe.get_doc('ToDo', toods[0].name);

Update

const frappe = require('frappe-core');
frappe.init();

// get all open todos
let todos = frappe.db.get_all('ToDo', ['name'], {status: "Open"});
let first_todo = frappe.get_doc('ToDo', toods[0].name);

first_todo.status = 'Closed';
first_todo.update();

Metadata

const frappe = require('frappe-core');
frappe.init();

let todo_meta = frappe.get_meta('ToDo');

// get all fields of type "Data"
let data_fields = todo_meta.fields.map(d => d.fieldtype=='Data' ? d : null);

Controllers

You can write event handlers in controllers, by declaring a .js file in the models/doctype/ folder along with the model file.

The name of the class must be the slugged name of the DocType

const frappe = require('frappe-core');

class todo extends frappe.document.Document {
	validate() {
		// set default status as "Open" if not set
		if (!this.status) {
			this.status = 'Open';
		}
	}
}

module.exports = { todo: todo };

Database

You can also directly write SQL with frappe.db.sql

const frappe = require('frappe-core');
frappe.init();

all_todos = frappe.db.sql('select name from todo');

REST API

You can directly access documents at /api/resource/:doctype

Create

  • URL: /api/resource/:doctype
  • Method: POST
  • Data: document properties

Example:

  • URL: /api/resource/todo
  • Method: POST

Data:

{
	"subject": "test",
	"description": "
}

Read

  • URL: /api/resource/:doctype/:name
  • Method: GET

Example:

  • URL: /api/resource/todo/uig7d1v12

Reponse:

{
	"name": "uig7d1v12",
	"owner": "guest",
	"modified_by": "guest",
	"creation": "2018-01-01T12:08:19.482Z",
	"modified": "2018-01-01T12:08:19.482Z",
	"docstatus": 0,
	"subject": "test 1",
	"description": "description 1",
	"status": "Open"
}

List

  • URL: /api/resource/:doctype/
  • Method: GET
  • Params (optional)
    • start: Page start
    • limit: Page limit

Example:

  • URL: /api/resource/todo

Response:

[
	{
		"name": "r4qxyki0i6",
		"subject": "test 1"
	},
	{
		"name": "efywwvtwcp",
		"subject": "test 1"
	},
	{
		"name": "9ioz05urgp",
		"subject": "test 1"
	}
]
