Managing Documents
Frappe.js Object-Relational-Mapper (ORM) helps you manage (create, read, update, delete) documents based on the DocTypes declared.
Documents are sub-classed from the frappe.document.Document
class.
All document write methods are asynchronous and return javascript Promise objects.
Initialize
Documents are initialized with the frappe.get_doc
method. If doctype
and name
are passed as parameters, then the document is fetched from the backend. If a simple object is passed, then object properties are set in the document.
// make a new todo
let todo = await frappe.get_doc({doctype: 'ToDo', subject: 'something'});
Create
You can insert a document in the backend with the insert
method.
// make a new todo
let todo = await frappe.get_doc({doctype: 'ToDo', subject: 'something'});
await todo.insert();
Read
You can read a document from the backend with the frappe.get_doc
method
// get all open todos
let todos = await frappe.db.get_all({doctype:'ToDo', fields:['name'], filters: {status: "Open"});
let first_todo = await frappe.get_doc('ToDo', toods[0].name);
Update
The update
method updates a document.
// get all open todos
let todos = await frappe.db.get_all({doctype:'ToDo', fields:['name'], filters: {status: "Open"});
let first_todo = await frappe.get_doc('ToDo', toods[0].name);
first_todo.status = 'Closed';
await first_todo.update();
Delete
The delete
method deletes a document.
// get all open todos
let todos = await frappe.db.get_all({doctype:'ToDo', fields:['name'], filters: {status: "Open"});
let first_todo = await frappe.get_doc('ToDo', toods[0].name);
await first_todo.delete();
Extending Documents
Each model can be extended by adding events in the controller class.
