Flask & Android

Swahili ICT

Mayelana nalolu hlelo lokusebenza

Lolu hlelo lokusebenza lusebenza njengephrojekthi yokufundisa esebenzayo egxile ekuboniseni indlela yokulandelela ngempumelelo kanye nokubona ngeso lengqondo izitayela zebhizinisi kudivayisi ephathwayo usebenzisa isistimu ye-backend exhunyiwe. Ibonisa isakhiwo esivamile lapho uhlaka lwewebhu (I-Flask) lusingatha ukuphathwa nokuhlaziywa kwedatha, kuyilapho uhlelo lokusebenza lweselula (i-Android, elisebenzisa ngokukhethekile i-Jetpack Compose) lusebenzisa futhi lunikeza lolu lwazi kumsebenzisi wokugcina.

Nakhu ukubuka okuningiliziwe kwezinjongo zokufunda nokusebenzisana phakathi kwezingxenye:

I. I-Backend (Flask) njengenjini yedatha ne-Analytics:
1. Ukuphathwa Kwedatha: I-backend ye-Flask inesibopho sokugcina nokuhlela idatha yebhizinisi ebalulekile, njengemininingwane yomkhiqizo kanye nokuthengiselana ngokuthengisa, kusetshenziswa isizindalwazi (i-SQLite kulokhu). Lokhu kufundisa ukusebenzisana kwesizindalwazi esiyisisekelo nemiqondo yokumodela idatha kusetshenziswa i-Flask-SQLAlchemy.
2. Ukuthuthukiswa kwe-API: Isici sokufunda esibalulekile ukuthuthukiswa kwama-APIs agcwele.
a. Isiphetho /api/ideshibhodi sibonisa indlela yokucubungula idatha eluhlaza, ukwenza izibalo zokuhlaziya (njengamathrendi okuthengisa, ukuqagela, nokusebenza komkhiqizo), bese uhlela lolu lwazi lube ifomethi ye-JSON emisiwe ukuze isetshenziswe kalula ngezinye izinhlelo zokusebenza. Lokhu kugqamisa izimiso zokudizayina kwe-API nokuhlelwa kwedatha.
b. Iphoyinti lokuphela /api/lokuzulazula libonisa ukuthi i-API ingaphinde inikeze imethadatha ukushayela ukusebenzelana komsebenzisi kohlelo lokusebenza olungaphambili, okwenza uhlelo lokusebenza lube namandla futhi lulungiseke kusukela kungemuva.
3. I-Backend Logic: Ikhodi ye-Python engaphakathi kwemizila ye-Flask ibonisa indlela yokusebenzisa ingqondo yebhizinisi, njengokurekhoda ukuthengisa, ukuvuselela uhlu lwempahla, nokwenza ukuhlaziya idatha eyisisekelo kusetshenziswa imitapo yolwazi efana ne-panda kanye ne-scikit-learn.

II. I-Frontend (I-Android Jetpack Compose) ukuze Ubone ngeso lengqondo:
1. Ukusetshenziswa Kwe-API: Umgomo wokufunda oyinhloko ohlangothini lwe-Android ukuqonda ukuthi uzenza kanjani izicelo zenethiwekhi ku-API engemuva, uthole izimpendulo ze-JSON, futhi uhlukanise le datha ezintweni ezisebenzisekayo ngaphakathi kohlelo lokusebenza lwe-Android. Imitapo yolwazi efana ne-Retrofit noma i-Volley (ku-Java/Kotlin) ngokuvamile izosetshenziselwa le njongo.
2. Iphrezentheshini Yedatha: Amazwibela ekhodi ye-DrawerItem aphakamisa ukuthi uhlelo lokusebenza lwe-Android luzoba nedrowa lokuzula. Idatha etholwe kusukela ku-/api/ideshibhodi ekugcineni izobese isetshenziselwe ukugcwalisa izikrini ezihlukile noma izingxenye ze-UI ngaphakathi kohlelo lokusebenza lwe-Android, kubonwa ngeso lengqondo izibalo zebhizinisi ngendlela esebenziseka kalula (isb., amashadi, amagrafu, izinhlu). I-Jetpack Compose inikezela ngohlaka lwesimanje lwe-UI oludalulayo lokwakha lezi zixhumanisi eziguqukayo.
3. I-Dynamic UI: Ukusetshenziswa okungahle kwe-/api/navigation endpoint kugcizelela ukuthi i-backend ingaba nomthelela kanjani kusakhiwo nokuqukethwe kokuzulazula kohlelo lokusebenza lweselula, okuvumela izibuyekezo noma izinguquko kumenyu yohlelo lokusebenza ngaphandle kokudinga ukukhishwa kohlelo lokusebenza olusha.

III. Inhloso Eyinhloko: Ukulandelela Okuthrendayo Kwebhizinisi Kuselula:

Inhloso enkulu yezemfundo ukukhombisa ukuhamba komsebenzi okuphelele kwalokhu:

Ukutholwa Kwedatha: Iqoqwa futhi igcinwe kanjani idatha yebhizinisi kusistimu ye-backend.
Ukuhlaziywa Kwedatha: Le datha eluhlaza ingacutshungulwa kanjani futhi ihlaziywe ukuze kuhlonzwe amathrendi anengqondo nemininingwane.
Ukulethwa kwe-API: Le mininingwane ingavezwa kanjani nge-API echazwe kahle.
Ukubonwa Kweselula: Uhlelo lokusebenza lweselula lungasebenzisa kanjani le API futhi luthule amathrendi ebhizinisi kubasebenzisi ngefomethi ecacile nesebenzayo, okubenza bakwazi ukuqapha ukusebenza futhi benze izinqumo ezinolwazi ngokuqondile kumadivayisi abo eselula.
Le phrojekthi inikeza ukuqonda okuyisisekelo kwezimiso ezibandakanyekayo ekwakheni izinhlelo zokusebenza zeselula ezixhunyiwe zobuhlakani bebhizinisi kanye nokwenziwa kwezinqumo okuqhutshwa idatha.
