ir.sequence: fields, relations and API

The ir.sequence model ("Sequence") is a persistent model declared by the Base module, then extended by 1 other module. It exposes 19 fields, 13 of them declared directly on the model; 14 fields from other models point to it. Below you will find every field with its technical name, type, label and relations, followed by an Odoo 19 JSON-2 API call.

19 of 19 fields shown

Technical name	Label	Type	Details
active	Active	`boolean`
code	Sequence Code	`char`
company_id	Company	`many2one` → res.company
date_range_ids	Subsequences	`one2many` → ir.sequence.date_range	inverse: `sequence_id`
implementation	Implementation While assigning a sequence number to a record, the 'no gap' sequence implementation ensures that each previous sequence number has been assigned already. While this sequence implementation will not skip any sequence number upon assignment, there can still be gaps in the sequence if records are deleted. The 'no gap' implementation is slower than the standard one.	`selection`	required Values: `standard` (Standard), `no_gap` (No gap)
name	Name	`char`	required
number_increment	Step The next number of the sequence will be incremented by this number	`integer`	required
number_next	Next Number Next number of this sequence	`integer`	required
number_next_actual	Actual Next Number Next number that will be used. This number can be incremented frequently so the displayed value might already be obsolete	`integer`	computed
padding	Sequence Size Odoo will automatically adds some '0' on the left of the 'Next Number' to get the required padding size.	`integer`	required
prefix	Prefix Prefix value of the record for the sequence	`char`
suffix	Suffix Suffix value of the record for the sequence	`char`
use_date_range	Use subsequences per date_range	`boolean`
create_date	Created on	`datetime`	read-onlyautomatic
create_uid	Created by	`many2one` → res.users	read-onlyautomatic
display_name	Display Name	`char`	read-onlycomputedautomatic
id	ID	`integer`	read-onlyautomatic
write_date	Last Updated on	`datetime`	read-onlyautomatic
write_uid	Last Updated by	`many2one` → res.users	read-onlyautomatic

Reading this model through the API

Odoo 19 JSON-2 API call reading the first five records with real fields of the model. Replace the instance, database and API key with your own.

curl

curl -X POST "https://your-instance.odoo.com/json/2/ir.sequence/search_read" \
  -H "Authorization: bearer $ODOO_API_KEY" \
  -H "X-Odoo-Database: your-db" \
  -H "Content-Type: application/json" \
  -d '{"domain":[],"fields":["name","implementation","number_increment","number_next","padding"],"limit":5}'

Python (requests)

import requests

BASE_URL = "https://your-instance.odoo.com/json/2"
headers = {"Authorization": f"bearer {API_KEY}", "X-Odoo-Database": "your-db"}

res = requests.post(
    f"{BASE_URL}/ir.sequence/search_read",
    headers=headers,
    json={"domain": [], "fields": ["name","implementation","number_increment","number_next","padding"], "limit": 5},
)
res.raise_for_status()
print(res.json())

External API access requires Odoo's Custom plan.
XML-RPC and JSON-RPC will be removed in Odoo 22 (fall 2028): use JSON-2.
The access rights and record rules of the key's user apply.
