You need to write an API for a simple application where football/soccer fans will create fantasy teams and will be able to sell or buy players.
-
User must be able to create an account and log in using the API.
-
Each user can have only one team (user is identified by an email)
-
When the user is signed up, they should get a team of 20 players (the system should generate players):
- 3 goalkeepers
- 6 defenders
- 6 midfielders
- 5 attackers
-
Each player has an initial value of $1.000.000.
-
Each team has an additional $5.000.000 to buy other players.
-
When logged in, a user can see their team and player information
-
Team has the following information:
- Team name, and a country (can be edited)
- Team value (sum of player values)
-
Player has the following information
- First name, last name, country (can be edited by a team owner)
- Age (random number from 18 to 40) and market value
-
A team owner can set the player on a transfer list
-
When a user places a player on a transfer list, they must set the asking price/value for this player. This value should be listed on a market list. When another user/team buys this player, they must be bought for this price.
-
Each user should be able to see all players on a transfer list and filter them by country, team name, player name, and a value.
-
With each transfer, team budgets are updated.
-
When a player is transferred to another team, their value should be increased between 10 and 100 per cent. Implement a random factor for this purpose.
- An administrator who can CRUD users, teams, players, add new players to the market or in the team and change all player/team information, including player’s value
- New users need to verify their account by email. Users should not be able to log in until this verification is complete.
- When a user fails to log in three times in a row, their account should be blocked automatically, and only admins and managers should be able to unblock it.
