types.ServerValues

types.ServerValues(df, sql, title, client)

Session-specific reactive values and client returned by QueryChat.server().

This dataclass contains all the session-specific reactive state for a QueryChat instance. Each session gets its own ServerValues to ensure proper isolation between concurrent sessions.

Attributes

Name	Type	Description
df	Callable[[], IntoFrameT]	A reactive Calc that returns the current filtered data frame or lazy frame. If the data source is lazy, returns a LazyFrame. If no SQL query has been set, this returns the unfiltered data from the data source. Call it like .df() to reactively read the current data.
sql	ReactiveStringOrNone	A reactive Value containing the current SQL query string. Access the value by calling .sql(), or set it with .sql.set("SELECT ..."). Returns None if no query has been set.
title	ReactiveStringOrNone	A reactive Value containing the current title for the query. The LLM provides this title when generating a new SQL query. Access it with .title(), or set it with .title.set("..."). Returns None if no title has been set.
client	ServerClient	Session chat client value. For real sessions this is a chatlas.Chat created by the client factory. For deferred stub sessions (where data_source is not set yet), this is a placeholder client that raises when accessed.
