Odoo RPC Client Library

Odoo RPC Client Library for Dart.

Features

• Initialize client with previously stored Odoo Session.
• Authenticate via database name, login and password.
• Issue JSON-RPC requests to JSON controllers.
• Execute public methods via CallKw.
• Get Odoo Session updates via stream.
• Terminate session (logout).
• Catch exceptions when session expires.

Usage

To use this plugin, add odoo_rpc as a dependency in your pubspec.yaml file. For example:

dependencies:
  odoo_rpc: ^0.4.5

Examples

Basic RPC-call

import 'dart:io';
import 'package:odoo_rpc/odoo_rpc.dart'

main() async {
  final client = OdooClient('https://my-db.odoo.com');
  try {
    await client.authenticate('my-db', 'admin', 'admin');
    final res = await client.callRPC('/web/session/modules', 'call', {});
    print('Installed modules: \n' + res.toString());
  } on OdooException catch (e) {
    print(e);
    client.close();
    exit(-1);
  }
  client.close();
}

RPC-Calls with tracking session changes. Odoo server will issue new session_id on each call.

import 'dart:io';
import 'package:odoo_rpc/odoo_rpc.dart'

sessionChanged(OdooSession sessionId) async {
  print('We got new session ID: ' + sessionId.id);
  store_session_somehow(sessionId);
}

main() async {
  var prev_session = restore_session_somehow();
  var client = OdooClient("https://my-db.odoo.com", prev_session);

  // Subscribe to session changes to store most recent one
  var subscription = client.sessionStream.listen(sessionChanged);

  try {
    final session = await client.authenticate('my-db', 'admin', 'admin');
    var res = await client.callRPC('/web/session/modules', 'call', {});
    print('Installed modules: \n' + res.toString());

    // logout
    await client.destroySession();
  } on OdooException catch (e) {
    print(e);
    subscription.cancel();
    client.close();
    exit(-1);
  }

  try {
    await client.checkSession();
  } on OdooSessionExpiredException {
    print('Session expired');
  }

  subscription.cancel();
  client.close();
}

Flutter example using FutureBuilder.

import 'package:flutter/material.dart';
import 'package:odoo_rpc/odoo_rpc.dart';

final orpc = OdooClient('https://my-odoo-instance.com');
void main() async {
  await orpc.authenticate('odoo-db', 'admin', 'admin');
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: HomePage(),
    );
  }
}

class HomePage extends StatelessWidget {
  Future<dynamic> fetchContacts() {
    return orpc.callKw({
      'model': 'res.partner',
      'method': 'search_read',
      'args': [],
      'kwargs': {
        'context': {'bin_size': true},
        'domain': [],
        'fields': ['id', 'name', 'email', '__last_update', 'image_128'],
        'limit': 80,
      },
    });
  }

  Widget buildListItem(Map<String, dynamic> record) {
    var unique = record['__last_update'] as String;
    unique = unique.replaceAll(RegExp(r'[^0-9]'), '');
    final avatarUrl =
        '${orpc.baseURL}/web/image?model=res.partner&field=image_128&id=${record["id"]}&unique=$unique';
    return ListTile(
      leading: CircleAvatar(backgroundImage: NetworkImage(avatarUrl)),
      title: Text(record['name']),
      subtitle: Text(record['email'] is String ? record['email'] : ''),
    );
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Contacts'),
      ),
      body: Center(
        child: FutureBuilder(
            future: fetchContacts(),
            builder: (BuildContext context, AsyncSnapshot<dynamic> snapshot) {
              if (snapshot.hasData) {
                return ListView.builder(
                    itemCount: snapshot.data.length,
                    itemBuilder: (context, index) {
                      final record =
                          snapshot.data[index] as Map<String, dynamic>;
                      return buildListItem(record);
                    });
              } else {
                if (snapshot.hasError) return Text('Unable to fetch data');
                return CircularProgressIndicator();
              }
            }),
      ),
    );
  }
}

For more complex usage consider odoo_repository as abstraction layer between your flutter app and Odoo backend.

Web platform notice

This package intentionally uses http package instead of dart:io so web platform could be supported. However RPC calls via web client (dart js) that is hosted on separate domain will not work due to CORS requests currently are not correctly handled by Odoo. See https://github.com/odoo/odoo/pull/37853 for the details.
