Running the application

Make sure you have ruby, rails, and postgres installed in your system.
In the project dir:
- create a .env file similar to the .env.example file in the project.
- run rails db:create to create the databases.
- run rails db:migrate to create the tables.
- run rails db:seed to populate some of the tables in order to get test data to work with.
After following the steps above, running rails server you should be able to get the app running in your localhost on port 3000
navigate to the route localhost:3000/graphiql and you should be in a position to see the graphql playground view that will allow you to make various requests to ineract with the data.

To create a transaction

run customers query to get a list of customers and select one id. save the customer id selected somewhere
```
query {
  customers {
    id
  }
}
```
run currencies query to get a list of currencies. Select 2 is and save them somewhere.
```
query {
  currencies {
    id
  }
}
```

now run the transaction mutation to create a transaction record.

mutation {
    createTransaction(input: {
      customerId: "saved_customer_id",
      inputAmount: "15.34",
      inputCurrencyId: "first_saved_currency_id",
      outputCurrencyId: "second_saved_currency_id"
    }) {
      transaction {
        id
        customer {
          firstName
          lastName
        }
        inputAmount
        inputCurrency {
          isoCode
        }
        outputAmount
        outputCurrency {
          isoCode
        }
        createdAt
      }
      errors
    }
}

Following this you should now have a transaction record that you can access by first quering the transactions then querying the transaction with id with the transaction ID to get the single transaction
