Update Vehicle Unit - Plugixa Car Rental for WordPress

Update Vehicle Unit - Plugixa Car Rental

PUT /plugixa-car-rental/v1/vehicle-units/{id}

Change a car. Only the fields you send are changed; PATCH works the same way.

The user needs the plugixa_car_rental_edit capability.

Note. Signing a pickup or return inspection PRO moves odometer forward on its own. It never moves it back.

Request

PUT https://your-site.example/wp-json/plugixa-car-rental/v1/vehicle-units/9

Path parameters

Name	Type	Description
`id`	`integer`	The car’s id

Request body

Content type: application/json

Field	Type	Required	Description
`vehicle_model_id`	`integer`	No	An existing vehicle model.
`plate`	`string`	No	Upper-cased, spaces collapsed. Must not be the plate of another car in the fleet: plates are compared on letters and digits only, so `AB-123-CD` and `ab 123 cd` are the same.
`vin`	`string`	No	17 letters and digits, without I, O or Q. Spaces are removed and it is upper-cased. Must not be another car’s.
`color`	`string`	No	Colour.
`odometer`	`integer`	No	Reading, not negative.
`home_location_id`	`integer`	No	The location the car is based at, or `0` for none. A car with a home location is only given to bookings picked up there; one without is given to any desk.
`notes`	`string`	No	Staff notes, plain text.
`status`	`string`	No	`published` or `unpublished`.
`modified_at`	`string`	No	The `modified_at` you read. When it differs from the stored one the update is refused with `409`. See Edit conflicts.

Fields you leave out keep their stored value. A field you send is checked the same way as on Create Vehicle Unit.

`409`	`plugixa_car_rental_duplicate_vin`	Another car in the fleet has this VIN.
`422`	`plugixa_car_rental_invalid_choice`	`status` is not `published` or `unpublished`. `data.allowed` lists the accepted values.
`422`	`plugixa_car_rental_not_a_number`	A number field was sent as something else. `data.field` names it.
`422`	`plugixa_car_rental_negative_number`	A number field that cannot be negative is. `data.field` names it.
`422`	`plugixa_car_rental_too_long`	A text field is longer than its column. `data.field` names it and `data.max` gives the limit.
`409`	`plugixa_car_rental_conflict`	You sent `modified_at` and the car has been saved by someone else since. `data.expected` and `data.current` carry both values.
