Events¶

CandidateSlashed¶

A candidate was slashed by amount due to failing to obtain a seat as member or runner-up.

Note that old members and runners-up are also candidates.

Attributes¶

Name	Type	Composition
candidate	`<T as frame_system::Config>::AccountId`	`AccountId`
amount	`BalanceOf<T>`	`u128`

ElectionError¶

Internal error happened while trying to perform election.

Attributes¶

No attributes

EmptyTerm¶

No (or not enough) candidates existed for this round. This is different from NewTerm(\[\]). See the description of NewTerm.

Attributes¶

No attributes

MemberKicked¶

A member has been removed. This should always be followed by either NewTerm or EmptyTerm.

Attributes¶

Name	Type	Composition
member	`<T as frame_system::Config>::AccountId`	`AccountId`

NewTerm¶

A new term with new_members. This indicates that enough candidates existed to run the election, not that enough have has been elected. The inner value must be examined for this purpose. A NewTerm(\[\]) indicates that some candidates got their bond slashed and none were elected, whilst EmptyTerm means that no candidates existed to begin with.

Attributes¶

Name	Type	Composition
new_members	`Vec<(<T as frame_system::Config>::AccountId, BalanceOf<T>)>`	`[('AccountId', 'u128')]`

Renounced¶

Someone has renounced their candidacy.

Attributes¶

Name	Type	Composition
candidate	`<T as frame_system::Config>::AccountId`	`AccountId`

SeatHolderSlashed¶

A seat holder was slashed by amount by being forcefully removed from the set.

Attributes¶

Name	Type	Composition
seat_holder	`<T as frame_system::Config>::AccountId`	`AccountId`
amount	`BalanceOf<T>`	`u128`

Storage functions¶

Candidates¶

The present candidate list. A current member or runner-up can never enter this vector and is always implicitly assumed to be a candidate.

Second element is the deposit.

Invariant: Always sorted based on account id.

Python¶

result = substrate.query(
    'Elections', 'Candidates', []
)

Return value¶

[('AccountId', 'u128')]

ElectionRounds¶

The total number of vote rounds that have happened, excluding the upcoming one.

Python¶

result = substrate.query(
    'Elections', 'ElectionRounds', []
)

Return value¶

'u32'

Members¶

The current elected members.

Invariant: Always sorted based on account id.

Python¶

result = substrate.query(
    'Elections', 'Members', []
)

Return value¶

[{'deposit': 'u128', 'stake': 'u128', 'who': 'AccountId'}]

RunnersUp¶

The current reserved runners-up.

Invariant: Always sorted based on rank (worse to best). Upon removal of a member, the last (i.e. best) runner-up will be replaced.

Python¶

result = substrate.query(
    'Elections', 'RunnersUp', []
)

Return value¶

[{'deposit': 'u128', 'stake': 'u128', 'who': 'AccountId'}]

Voting¶

Votes and locked stake of a particular voter.

TWOX-NOTE: SAFE as AccountId is a crypto hash.

Python¶

result = substrate.query(
    'Elections', 'Voting', ['AccountId']
)

Return value¶

{'deposit': 'u128', 'stake': 'u128', 'votes': ['AccountId']}

Constants¶

CandidacyBond¶

How much should be locked up in order to submit one's candidacy.

Value¶

500000000000000

Python¶

constant = substrate.get_constant('Elections', 'CandidacyBond')

DesiredMembers¶

Number of members to elect.

Value¶

Python¶

constant = substrate.get_constant('Elections', 'DesiredMembers')

DesiredRunnersUp¶

Number of runners_up to keep.

Value¶

Python¶

constant = substrate.get_constant('Elections', 'DesiredRunnersUp')

MaxCandidates¶

The maximum number of candidates in a phragmen election.

Warning: This impacts the size of the election which is run onchain. Chose wisely, and consider how it will impact T::WeightInfo::election_phragmen.

When this limit is reached no more candidates are accepted in the election.

Value¶

Python¶

constant = substrate.get_constant('Elections', 'MaxCandidates')

MaxVoters¶

The maximum number of voters to allow in a phragmen election.

Warning: This impacts the size of the election which is run onchain. Chose wisely, and consider how it will impact T::WeightInfo::election_phragmen.

When the limit is reached the new voters are ignored.

Value¶

Python¶

constant = substrate.get_constant('Elections', 'MaxVoters')

MaxVotesPerVoter¶

Maximum numbers of votes per voter.

Warning: This impacts the size of the election which is run onchain. Chose wisely, and consider how it will impact T::WeightInfo::election_phragmen.

Value¶

Python¶

constant = substrate.get_constant('Elections', 'MaxVotesPerVoter')

PalletId¶

Identifier for the elections-phragmen pallet's lock

Value¶

'0x706872656c656374'

Python¶

constant = substrate.get_constant('Elections', 'PalletId')

TermDuration¶

How long each seat is kept. This defines the next block number at which an election round will happen. If set to zero, no elections are ever triggered and the module will be in passive mode.

Value¶

Python¶

constant = substrate.get_constant('Elections', 'TermDuration')

VotingBondBase¶

Base deposit associated with voting.

This should be sensibly high to economically ensure the pallet cannot be attacked by creating a gigantic number of votes.

Value¶

1000000000000

Python¶

constant = substrate.get_constant('Elections', 'VotingBondBase')

VotingBondFactor¶

The amount of bond that need to be locked for each vote (32 bytes).

Value¶

1000000000000

Python¶

constant = substrate.get_constant('Elections', 'VotingBondFactor')

Errors¶

DuplicatedCandidate¶

Duplicated candidate submission.

InsufficientCandidateFunds¶

Candidate does not have enough funds.

InvalidRenouncing¶

The renouncing origin presented a wrong Renouncing parameter.

InvalidReplacement¶

Prediction regarding replacement after member removal is wrong.

InvalidVoteCount¶

The provided count of number of votes is incorrect.

InvalidWitnessData¶

The provided count of number of candidates is incorrect.

LowBalance¶

Cannot vote with stake less than minimum balance.

MaximumVotesExceeded¶

Cannot vote more than maximum allowed.

MemberSubmit¶

Member cannot re-submit candidacy.
