Currency code normalization

Logic

FE uppercases Currency Code while the operator types., The type lookup also uppercases the code before checking the crypto lookup., Backend uppercases code again before saving the created currency.

Currency type suggestion

Logic

The create form requests the currencies list with a large limit to read the isCurrenciesCrypto lookup., When the uppercase code exists in the lookup and its value is true, FE sets type to Crypto., When the uppercase code exists in the lookup and its value is false, FE sets type to Fiat., When the code is missing from the lookup, FE sets type to Fiat., The visible Currency Type selector is disabled, so the operator can review but not manually override it from this form.

Submit payload casting

Logic

Before submit, FE casts exchangeRate to a string., Before submit, FE casts marketingRatio to a string., Before submit, FE casts loyaltyPoint to a string., The backend create flow validates its accepted fields after request parsing.

Create validation

Logic

FE validates Currency Name, Currency Code, Currency Symbol, Exchange Rate, Loyalty Point, and Currency Type., Backend validates name, code, exchangeRate, symbol, type, and loyaltyPoint., Backend rejects duplicate currency codes before create., Backend creates the row inside a transaction.

Marketing ratio create caveat

Logic

FE renders MRKTG Ratio to EUR and sends marketingRatio on submit., The verified FE create schema does not define an explicit marketingRatio validation rule., Backend argument filtering uses the create constraints and removes marketingRatio before create logic reads the sanitized payload., The currency model default for marketingRatio is 0 when create does not accept a value., The saved-record update flow includes marketingRatio in its constraints and persists it from the detail screen.

Cancel flow

Logic

Cancel calls router back navigation., Cancel does not submit the form., No backend create request is sent when the operator cancels.

Create success flow

Logic

On successful backend response, FE resets the form., FE shows a Currency created success toast., FE clears submitting state., FE returns the operator to the previous page.

Currency Name

Display name saved for the new currency record.

Group

identity

Data Type

string

Validation

Frontend: Required., Letters and spaces only., Minimum 3 characters., Maximum 50 characters. | Backend: Required., Letters and spaces only., Minimum 3 characters., Maximum 50 characters.

Currency Code

Three-letter currency code used to identify the currency.

Group

identity

Data Type

string

Validation

Frontend: Required., Letters and spaces according to the visible FE schema., Maximum 3 characters., Uppercased while typing. | Backend: Required., Exactly 3 characters., Letters only., Must not duplicate an existing currency code.

Caveats

The FE uppercases the value while the operator types., The backend uppercases the saved code again during create., Backend duplicate-code validation rejects an already configured code.

Currency Symbol

Visible currency symbol used in formatting.

Group

identity

Data Type

string

Validation

Frontend: Required., Maximum 5 characters. | Backend: Required.

Exchange Rate

Stored exchange-rate value for the currency.

Group

rates

Data Type

number

Validation

Frontend: Required., Must be a number., Must be positive. | Backend: Required., Numeric-looking string., Length 1 to 10.

Submit Transform

FE stringifies this value before calling the create endpoint.

MRKTG Ratio to EUR

Marketing ratio used by other CRM flows when amount conversion relies on marketing-rate logic instead of pure exchange rate.

Group

rates

Data Type

number

Caveats

The FE helper text says this value affects bonus and bet-limit amounts., The FE sends this field on create, but backend create input filtering removes it because `marketingRatio` is not in the create constraints., New rows use the currency model default when create does not accept a marketing-ratio value., Set or correct this value on the saved-record detail screen, where the update flow accepts `marketingRatio`.

Validation

Frontend: No explicit FE schema rule found in the verified create schema. | Backend: No explicit create constraint exists for this field, so create input filtering removes it., The saved-record update flow accepts this field.

Submit Transform

FE stringifies this value before calling the create endpoint.

Loyalty Point

Loyalty-point value saved with the currency.

Group

rates

Data Type

number

Validation

Frontend: Required., Must be a number., Must be positive. | Backend: Required., Numeric-looking string.

Submit Transform

FE stringifies this value before calling the create endpoint.

Currency Type

Fiat/Crypto classification saved for the new currency.

Group

classification

Data Type

enum

Enum Values

Crypto, Fiat

Display

0: Crypto | 1: Fiat

Default

Fiat

Caveats

The FE auto-suggests the value from `isCurrenciesCrypto` when the entered code matches a known lookup entry., The visible selector is disabled in the verified create form, so operators can review the value but not manually override it here., Unknown codes default the visible type to Fiat.
