Python¶

result = substrate.query(
    'TechnicalCommittee', 'Prime', []
)

Return value¶

'[u8; 20]'

ProposalCount¶

Proposals so far.

Python¶

result = substrate.query(
    'TechnicalCommittee', 'ProposalCount', []
)

Return value¶

'u32'

ProposalOf¶

Actual proposal for a given hash, if it's current.

Python¶

result = substrate.query(
    'TechnicalCommittee', 'ProposalOf', ['scale_info::12']
)

Return value¶

'Call'

Proposals¶

The hashes of the active proposals.

Python¶

result = substrate.query(
    'TechnicalCommittee', 'Proposals', []
)

Return value¶

['scale_info::12']

Voting¶

Votes on a given proposal, if it is ongoing.

Python¶

result = substrate.query(
    'TechnicalCommittee', 'Voting', ['scale_info::12']
)

Return value¶

{'ayes': ['[u8; 20]'], 'end': 'u32', 'index': 'u32', 'nays': ['[u8; 20]'], 'threshold': 'u32'}

Members are already initialized!

DuplicateProposal¶

Duplicate proposals not allowed

DuplicateVote¶

Duplicate vote ignored

NotMember¶

TooManyProposals¶

There can only be a maximum of MaxProposals active proposals.

WrongIndex¶

Mismatched index

WrongProposalLength¶

The given length bound for the proposal was too low.

WrongProposalWeight¶

The given weight bound for the proposal was too low.
