Valūtas kursi

l27 · February 15, 2017

Meklēju gatavu biblioteku valūtas kursiem, kura pati ielādē, saglabā un konvertē. Varbūt kādam ir idejas?

aaxc · February 15, 2017

Ielādē no kurienes? Latvijas valūtas kursus? Polijas? Ja tas nav svarīgi, un vajag tikai aptuvenos datus lai nojaustu, cik varētu maksāt, bet tie netiks izmantoti reāliem maksājumiem, tad var idejas pasmelties šeit: http://stackoverflow.com/questions/3139879/how-do-i-get-currency-exchange-rates-via-an-api-such-as-google-finance

Vajag kursus grāmatvedībai. Šis neder, bet ir interesants.

Grāmatvedībai vajag Latvijas Bankas oficiālos kursus - XML, CSV. Uz ko tu vēl gribi konvertēt?

F3llony · February 15, 2017

Grāmatvedībai kam, KĀDĀ VALSTĪ? LV pamatā piemēro ECB references valūtu kursus, kur valūtas kurss attaisnojuma dokumentos tiek pieņemts ECB kurss darba dienas sākumā. ECB ir XML exportam ar visiem references kursiem.

jurchiks · February 15, 2017

Īsāk sakot, not enough information. Pat ja der ECB, tad kur tev viņus vajag saglabāt un uz ko konvertēt ir subjektīvi, tāpēc šaubos, ka būs bibliotēka, kas to darīs tieši tā, kā tev vajag.

aaxc · February 15, 2017

Un vēl kāds sīkums: ja ir vajadzīgs grāmatvedībai, tad kā tu gribi konvertēt? Vienmēr pēc aktuālā kursa? Vai pēc kursa, kas bijis dienā, kad nauda ienākusi? Varbūt tomēr pēc tā, kas bijis dienā, kad veikts maksājums? Vai dienā kad reķins izrakstīts? Respektīvi, tu nevaru vienkārši padod vienu summu un saņemt atpakaļ citu, tev ir jāzin vairaki papildus nosacījumi, lai to izdarītu korekti.

Aah, un kurs var mainīties pēc summas apjoma. Lielākām summām bankas noteikti dos izdevīgākus valūtas kursus kā mazajām.

Laikam būs jāizmanto sava vecā bibliotēka (jāpārtaisa vienīgi uz Yii2): https://github.com/DBRisinajumi/fcrn

Domāju, ka ir kas labāks uztaisīts!

Nodrošina:

- valūtu kursu ieladi no Latvijas bankas, leišu bankas (viņiem ir speciāls gramatvedībai kurss) un krievu bankas

- kursi saglabājas datubāze (jāielāde vienreiz)

- konvertē

- var izmantot SQL statementos

Vaitad kursi katru dienu nemainās?
