The JS ORM

The ORM is a service you can use in Owl components.

src/odoo/addons/web/static/src/core/orm_service.js

It is essentially just a wrapper around the RPC (Remote Procedure Call) service.

It exposes the following methods:

    create(model, records, kwargs = {}) {
        validateArray("records", records);
        for (const record of records) {
            validateObject("record", record);
        }
        return this.call(model, "create", records, kwargs);
    }

    nameGet(model, ids, kwargs = {}) {
        validatePrimitiveList("ids", "number", ids);
        if (!ids.length) {
            return Promise.resolve([]);
        }
        return this.call(model, "name_get", [ids], kwargs);
    }

    read(model, ids, fields, kwargs = {}) {
        validatePrimitiveList("ids", "number", ids);
        if (fields) {
            validatePrimitiveList("fields", "string", fields);
        }
        if (!ids.length) {
            return Promise.resolve([]);
        }
        return this.call(model, "read", [ids, fields], kwargs);
    }

    readGroup(model, domain, fields, groupby, kwargs = {}) {
        validateArray("domain", domain);
        validatePrimitiveList("fields", "string", fields);
        validatePrimitiveList("groupby", "string", groupby);
        return this.call(model, "read_group", [], { ...kwargs, domain, fields, groupby });
    }

    search(model, domain, kwargs = {}) {
        validateArray("domain", domain);
        return this.call(model, "search", [domain], kwargs);
    }

    searchRead(model, domain, fields, kwargs = {}) {
        validateArray("domain", domain);
        if (fields) {
            validatePrimitiveList("fields", "string", fields);
        }
        return this.call(model, "search_read", [], { ...kwargs, domain, fields });
    }

    searchCount(model, domain, kwargs = {}) {
        validateArray("domain", domain);
        return this.call(model, "search_count", [domain], kwargs);
    }

    unlink(model, ids, kwargs = {}) {
        validatePrimitiveList("ids", "number", ids);
        if (!ids.length) {
            return true;
        }
        return this.call(model, "unlink", [ids], kwargs);
    }

    webReadGroup(model, domain, fields, groupby, kwargs = {}) {
        validateArray("domain", domain);
        validatePrimitiveList("fields", "string", fields);
        validatePrimitiveList("groupby", "string", groupby);
        return this.call(model, "web_read_group", [], {
            ...kwargs,
            groupby,
            domain,
            fields,
        });
    }

    webSearchRead(model, domain, fields, kwargs = {}) {
        validateArray("domain", domain);
        validatePrimitiveList("fields", "string", fields);
        return this.call(model, "web_search_read", [], { ...kwargs, domain, fields });
    }

    write(model, ids, data, kwargs = {}) {
        validatePrimitiveList("ids", "number", ids);
        validateObject("data", data);
        return this.call(model, "write", [ids, data], kwargs);
    }

Update

Update uses the write method.

Example:

this.orm.write(`module.model`, [31], { field: 'New Value' })
