Representation of the client devices.

class camcops_server.cc_modules.cc_device.Device(**kwargs)

Represents a tablet (client) device.

__init__(**kwargs)

A simple constructor that allows initialization from kwargs.

Sets attributes on the constructed instance using the names and values in kwargs.

Only keys that are present as attributes of the instance’s class are allowed. These could be, for example, any mapped columns or relationships.

classmethod get_device_by_id(dbsession: sqlalchemy.orm.session.Session, device_id: int) → Optional[camcops_server.cc_modules.cc_device.Device]

Returns a device by its integer ID.

classmethod get_device_by_name(dbsession: sqlalchemy.orm.session.Session, device_name: str) → Optional[camcops_server.cc_modules.cc_device.Device]

Returns a device by its name.

get_friendly_name() → str

Get the device’s friendly name (or failing that, its name).

get_friendly_name_and_id() → str

Get a formatted representation of the device (name, ID, friendly name).

get_id() → int

Get the device’s integer ID.

classmethod get_server_device(dbsession: sqlalchemy.orm.session.Session) → camcops_server.cc_modules.cc_device.Device

Return the special device meaning “the server”, creating it if it doesn’t already exist.

is_valid() → bool

Having instantiated an instance with Device(device_id), this function reports whether it is a valid device, i.e. is it in the database?

class camcops_server.cc_modules.cc_device.DeviceReport

Report to show registered devices. This is a superuser-only report, so we do not override superuser_only.

get_query(req: CamcopsRequest) → sqlalchemy.orm.query.Query

Overriding this function is one way of providing a report. (The other is get_rows_colnames().)

To override this function, return the SQLAlchemy Base Select statement or the SQLAlchemy ORM Query to execute the report.

Parameters are passed in via the request.
