Sebastian Abondano fa09f399d8 GraphQL API token_transfers query ... Why: * For GraphQL API users to be able to fetch token transfer events. RPC API users could use this instead of the `tokentx` RPC API action. Example usage: 1. ``` query ($token_contract_address_hash: AddressHash!, $first: Int!) { token_transfers(token_contract_address_hash: $token_contract_address_hash, first: $first) { edges { node { amount block_number log_index token_id from_address_hash to_address_hash token_contract_address_hash transaction_hash } } } } ``` 2. with pagination support via [Relay Cursor Connections](https://facebook.github.io/relay/graphql/connections.htm) ``` query ($token_contract_address_hash: AddressHash!, $first: Int!, $after: ID!) { token_transfers(token_contract_address_hash: $token_contract_address_hash, first: $first, after: $after) { page_info { has_next_page has_previous_page } edges { node { amount from_address_hash to_address_hash } cursor } } } ``` * Issue link: n/a This change addresses the need by: * Editing the node interface and node field in `BlockScoutWeb.Schema` to support token transfers. * Adding `token_transfers` connection field to root query object in `BlockScoutWeb.Schema` * Making `token_transfer` object types a node type and adding a few new fields to it, in `BlockScoutWeb.Schema.Types`. * Creating `BlockScoutWeb.Resolvers.TokenTransfer` with resolver functions for getting token transfers. * Adding `get_token_transfer/1` and `list_token_transfers_query/1` to `Explorer.GraphQL`. These two functions are used by the new resolver functions mentioned above. * Editing RPC API docs to reference the new GraphQL query field added in this commit.		6 years ago
