[Tango REST API] Database endpoint

# 5 years ago
hardion	The Tango REST api does not define anything to access the database without to know exactly the name of the database device i.e sys/database/2 It would be great if the client application can just call a endpoint like /database à la pytango.

Ingvord	@hardion, I am not sure REST can get a reference to database. Could you please provide a guideline how it is done in Python? Feature will be useful no doubts.

hardion	Hi @ingvord, I means just a way to access the Database device without to know the name i.e sys/database/2 A way would be to link /tango/rest/rc3/hosts/computer/10000/devices/sys/database/2 to /tango/rest/rc3/hosts/computer/10000/database (of course sys/database/2 can be something else) or that GET /tango/rest/rc3/hosts/computer/10000 gives the name of the database. { …, "name":"sys\/database\/2", "databases":["/tango/rest/rc3/hosts/computer/10000/sys/database/2"] … } But it's maybe probably the responsibility of the client application to do that.

Hi @ingvord,

I means just a way to access the Database device without to know the name i.e sys/database/2

A way would be to link /tango/rest/rc3/hosts/computer/10000/devices/sys/database/2 to
/tango/rest/rc3/hosts/computer/10000/database (of course sys/database/2 can be something else)

or that

GET /tango/rest/rc3/hosts/computer/10000 gives the name of the database.

{ …,
"name":"sys\/database\/2",
"databases":["/tango/rest/rc3/hosts/computer/10000/sys/database/2"]
…
}

But it's maybe probably the responsibility of the client application to do that.
