MYSQL convert complex join outputs to JSON with Python
1
This is an example MYSQL query for a tournament system.
SELECT
tournament_game.game_identifier AS match_number,
tournament_game.id AS match_id,
tournament_game_round.round_number AS match_round_number,
tournament_game_round_team.team_identifier,
tournament_game_round_team_player.tournament_game_round_team_id,
tournament_game_round_team_player.isHost,
tournament_game_round_team_player.tournament_registration_id,
user_platform_name.name AS player_name
FROM tournament_game
LEFT JOIN tournament_game_round ON tournament_game_round.tournament_game_id = tournament_game.id
LEFT JOIN tournament_game_round_team ON tournament_game_round_team.tournament_game_round_id = tournament_game_round.id
LEFT JOIN tournament_game_round_team_player ON tournament_game_round_team_player.tournament_game_round_team_id = tournament_game_round_team.id
LEFT JOIN tournament_registration ON tournament_registration.id = tournament_game_round_team_player.tournament_registration_id
LEFT JOIN user_platform_name ON user_platform_name.id = tournament_registration.user_platform_name_id
WHERE tournament_game.id = %s;
Which outputs:
1 264 0 0 125 1 66 playername1
1 264 1 0 127 0 66 playername1
1 264 0 1 126 0 69 playername2
1 264 1 1 128 1 69 playername2
I want the data to be formatted in JSON as:
{
match_id: a.match_id,
matches: [
{
match_number: a.match_number,
match_rounds: [
{
match_round_number: a.match_round_number,
match_round_teams: [
{
team_identifier: a.team_identifier,
team_players: [
{
player_name: a.player_name,
isHost: a.isHost,
rego_id: a.tournament_registration_id
}
]
}
]
}
]
}
]
};
I can get the desired result with a very long ugly and complex python algorithm however I want to know if there is a pre-existing method of attaining the desired results easily. As I'm sure this is a common roadblock for learning developers like me.
If there is a better way to make the query I'm all ears.
