Session information for client devices (tablets etc.).

class camcops_server.cc_modules.cc_tabletsession.TabletSession(req: CamcopsRequest)[source]

Represents session information for client devices. They use HTTPS POST calls and do not bother with cookies.

__init__(req: CamcopsRequest) None[source]
property cope_with_deleted_patient_descriptors: bool

Must we cope with an old client that had ID descriptors in the Patient table?

property cope_with_old_idnums: bool

Must we cope with an old client that had ID numbers embedded in the Patient table?

property device: Optional[camcops_server.cc_modules.cc_device.Device]

Returns the camcops_server.cc_modules.cc_device.Device associated with this request/session, or None.

property device_id: Optional[int]

Returns the integer device ID, if known.

ensure_device_registered() None[source]

Ensure the device is registered. Raises UserErrorException on failure.

ensure_valid_device_and_user_for_uploading() None[source]

Ensure the device/username/password combination is valid for uploading. Raises UserErrorException on failure.

ensure_valid_user_for_device_registration() None[source]

Ensure the username/password combination is valid for device registration. Raises UserErrorException on failure.

property explicit_pkname_for_upload_table: bool

Is the client a nice new one that explicitly names the primary key when uploading tables?

is_device_registered() bool[source]

Is the device registered with our server?

property pkname_in_upload_table_neither_first_nor_explicit

Is the client a particularly tricky old version that is a C++ client (generally a good thing, but meaning that the primary key might not be the first field in uploaded tables) but had a bug such that it did not explicitly name its PK either?

See discussion of bug in NetworkManager::sendTableWhole (C++). For these versions, the only safe thing is to take "id" as the name of the (client-side) primary key.


Re-fetch the device information from the database. (Or, at least, do so when it’s next required.)

set_session_id_token(session_id: int, session_token: str) None[source]

Sets the session ID and token. Typical situation:

property user_id: Optional[int]

Returns the integer user ID, if known.
