api/permissions

Im having trouble setting permissions for devices. I'm getting a 400 response from the server along with this error message:

Cannot add or update a child row: a foreign key constraint fails (`DATABASE`.`user_device`, CONSTRAINT `fk_user_device_deviceid` FOREIGN KEY (`deviceid`) REFERENCES `devices` (`id`) ON DELETE CASCADE) - MySQLIntegrityConstraintViolationException (... < QueryBuilder:477 < DataManager:438 < PermissionsResource:62 < ...)

any idea what could be causing this error?

https://github.com/tananaev/traccar/issues/2172 maybe.....

Compare your request with what official app sends. If it doesn't help, provide request here.

Yup I was using the swagger.io to send the request and was getting the same error. The request was sent as:

curl -X POST "http://myipaddress:8082/api/permissions" -H "accept: application/json" -H "Content-Type: application/json" -d "{ \"userId\": 3, \"deviceId\": 632673, \"groupId\": 0, \"geofenceId\": 4, \"calendarId\": 0, \"attributeId\": 0, \"driverId\": 0, \"managedUserId\": 0}"

Have you compared it with what official we app sends?

That led me to the answer Anton!! You're a damn genius.

edit:

for anyone looking I was sending the wrong device ID to the server. Checking the web app helped me tighten up that server call as well as all of the others.

I am try, error 400 also, I am use admin login, some body help me ?

What is the error message?

For any technical person this error message should be pretty clear. Your device id doesn't exist in the database.

hello everyone could support me I have the following problem and I do not understand what the problem is

Referential integrity constraint violation: "FK_USER_DEVICE_USERID: PUBLIC.TC_USER_DEVICE FOREIGN KEY(USERID) REFERENCES PUBLIC.TC_USERS(ID) (5)"; SQL statement: INSERT INTO tc_user_device (userId, deviceId) VALUES (?, ?) [23506-200] - JdbcSQLIntegrityConstraintViolationException (... < QueryBuilder:480 < DataManager:441 < PermissionsResource:63 < ...)

The user with whom you create both the group and the divice is administrator type

Most likely you are using wrong userId or deviceId value.

sorry was this mistake :

Table "TC_DEVICE_GROUP" not found; SQL statement: INSERT INTO tc_device_group (deviceId, groupId) VALUES (?, ?) [42102-200] - JdbcSQLSyntaxErrorException (... < QueryBuilder:65 < *:135 < DataManager:438 < PermissionsResource:63 < ...) lo que mando es. 

$data='{"deviceId":"'.$deviceId.'","groupId":"'.$groupId.'"}'; 
return self::curl('/api/permissions','POST',$sessionId,$data,array(self::$jsonC));

I found the problem the table does not exist TC_DEVICE_GROUP,
what if it exists is in the table of TC_DEVICES a field called GROUPID, I suppose that the relation should be saved there.

the problem is that the API in the "Permission: object" method asks me:
deviceId: integer
Device Id, can be first parameter or second only in combination with userId

groupId: integer
Group Id, can be first parameter or second only in combination with userId

and it is who executes and sends me INSERT INTO tc_device_group

Question will it be that you need to update traccar or is there a way to upload the missing tables and that the system does not thunder to enter them manually or what would be your recommendation?
