call = substrate.compose_call(
    'Initializer', 'force_approve', {'up_to': 'u32'}
)

Storage functions

---

BufferedSessionChanges

Buffered session changes along with the block number at which they should be applied.

Typically this will be empty or one element long. Apart from that this item never hits the storage.

However this is a Vec regardless to handle various edge cases that may occur at runtime upgrade boundaries or if governance intervenes.

Python

result = substrate.query(
    'Initializer', 'BufferedSessionChanges', []
)

Return value

[{'queued': ['[u8; 32]'], 'session_index': 'u32', 'validators': ['[u8; 32]']}]

---

HasInitialized

Whether the parachains modules have been initialized within this block.

Semantically a bool, but this guarantees it should never hit the trie, as this is cleared in on_finalize and Frame optimizes None values to be empty values.

As a bool, set(false) and remove() both lead to the next get() being false, but one of them writes to the trie and one does not. This confusion makes Option<()> more suitable for the semantics of this variable.

Python

result = substrate.query(
    'Initializer', 'HasInitialized', []
)

Return value

()
