Update by id (generated API)¶
Changes the fields you send on one row and leaves the others alone. The row is found by its primary key, or by the column you name.
| Method | PUT |
| URL | /api/gen/admin/mysql8/inventory/customers/update-by-id/:id[/:primaryKey] |
| Body | the fields to change |
| Query params | select, deep, upsert, returnDocument, throwErrorIfRecordNotFound, find |
| Answer | data : the row after the change (or before, with returnDocument=before) |
| Databases | MongoDB, MySQL, MariaDB, PostgreSQL, SQL Server, Oracle, TiDB, Percona |
| Cached | no (a write ; it resets the cache of the table) |
| From code | g.sys.db.gen.updateByIdGen |
| API id | GEN_PUT_UPDATE_BY_ID (groups, settings, hooks, WebSocket subscriptions) |
| The other family | Update by id as a schema API |
Schemaless : the data passes as it is
The generated APIs never read the schema of the table. Nothing is converted, validated, defaulted, encrypted or numbered : what you send is what the database gets, and a filter matches the type you send ("22" does not match the number 22). On MongoDB, strings which look like ObjectIds are converted. Every table has these APIs, with or without a schema ; the same operations under /api/schema apply the schema.
The URL¶
/api/gen/admin/mysql8/inventory/customers/update-by-id/:id[/:primaryKey] : replace admin with the user path of your account, mysql8 with your instance, inventory with the database and customers with the table. The examples use this table :
| customer_id | first_name | last_name | last_update | pincode | isActive |
|---|---|---|---|---|---|
| 1 | Bob | lin | 2022-11-14 04: 34: 58 | 382345 | 1 |
| 2 | Alice | Page | 2022-10-15 02: 10: 40 | 382346 | 1 |
| 3 | Mallory | Brown | 2022-09-13 03: 44: 05 | 382347 | 1 |
| 4 | Eve | Mathly | 2022-11-12 01: 59: 33 | 382348 | 1 |
| 5 | Eve | Page | 2022-11-12 01: 59: 33 | 382349 | 1 |
Some fields¶
{
"success": true,
"statusCode": 200,
"data": { "customer_id": 1, "first_name": "Bob", "last_name": "lin", "last_update": "2022-11-14T04:34:58.000Z", "pincode": 382330, "isActive": 1 }
}
- Send only what changes. Several fields at once are fine. On MongoDB, a nested key like
"address.city"updates that path.
By another column¶
- The row whose
first_nameisBobis updated. The column named as the key can itself be in the body :/update-by-id/Mallory/first_namewith{ "first_name": "Alice" }renames her.
Insert when missing : upsert¶
- No row with
customer_id999 : one is inserted with the id and the body (the body is validated as a save). A row exists : it is updated. On every database.
The row before the change¶
- The answer holds the row as it was ; the update happens all the same. Default :
after. See returnDocument.
Unknown id¶
- By default an unknown id answers
success: truewithdata: nulland changes nothing. With?throwErrorIfRecordNotFound=trueit answers404andRecord not found. findadds conditions the row must match :?find={isActive:1}. A pre hook can add the condition for every call.
Fields and related rows in the answer¶
PUT /api/gen/admin/mysql8/inventory/customers/update-by-id/1?select=first_name,last_name&deep=[{s_key:'customer_id',t_col:'orders',t_key:'customer_id'}]
From your code¶
g.sys.db.gen.updateByIdGen makes the same call from custom APIs, hooks, events, schedulers and test cases, with the same headers and params. Pass true as the second argument to get the whole response envelope instead of data.
Headers¶
Every call takes the request headers : the tokens, x-am-response-case, x-am-content-type-response (JSON, XML, YAML…), x-am-response-object-type: make_flat, x-am-cache-control, x-am-get-encrypted-data, x-am-internationalization, x-am-tenant-username, x-am-meta.
Errors¶
| Code | When |
|---|---|
401 |
The token in x-am-authorization is missing or invalid. |
403 |
No group of the API user grants this API of this table, or a field of the request. |
404 |
The instance, database or table of the URL does not exist. |
400 |
The query or the body is wrong : the error messages say which key and why. |
