Hello wakuu.

Current anafanya migration ya system inatoka language moja inaenda nyingine, tuna shift kwa sababu hii system ina deal sana na APIs tunahamia kwenye language ambayo itatupa ufanisi kwenye utegenezaji wa API na mambo ya security.

Sasa hii system walio code, sijajua walikua wanawaza nini. variables, functions, class zina majina ya ajabu

Yani jina la function hali indicate kazi ya hiyo function
Mfano, function inayo return exchange rate kati ya usd na tzs "exchangefromusdtotzs"

Labda variable ya timestamp imeandikwa ivi "usertransactiontimeanddate"

Kiujumla kama mtu una fanya development ya app, website au chochote jaribu ku code kwa clean andika variables majina yake vizuri

Yani baadae ukija kudanya update itakutesa, yani mtu kazi ya 8 months au 10 months mnafanya mwaka na nusu
 
Braza acha kujificha kwenye kichaka cha variable/function/class/methods Names....We kazi ya miezi nane 8 inarukaje mpaka miez 8 mingine???

Kama majina yapo na hizo file zipo si u just jump to find them ..ugum uko wapi hata kama zingekua na majin mazuri stahiki ?maana pale zilipo hizo sasa ndipo zingekuwepo hizo unazotaka sasa shida iko wapi??? 😂😂😂

Kabidhi kaz ya watu bwana....usimdanganye bosi kwa kumpa sababu kama hizo.

Halaf APIs doeant really care kivileeee mambo ya language gan imetumika ku code system.It doesnt need to understand the architecture of entire system.just set the instructions on what u want it to achieve n it will provide to u.

NB.
Mwisho naomba nikuchek personally regarding hizo mambo za API😎😎😎

😁 hapo shid iko wap mkuu...mfano mimi specifically kwenye mfano uloutumia hapo wa password natumia sana 'pswrd' kama variable name.The thing is anajarb kuwa kuweka katika namna rahis kukumbuka.Project kubwa imagine ina variablea ngapi mpaka ikaishe.Na variables/methods hizo unaweza ukajikuta unazi call kwenye different files??? Sas ukishindwa kuzipa majin memorable we mwenyewe zitakuchanganya...

Vipi HAPO:

exchangeFromTZStoUSD
Click to expand...
hapo mtu unashidwa kueewa ina return exchange rates au nini, labda hii function ingukua

Python: 
class Currencies:
  
    class Exchange:
          
            class Rates:
                    def USDTZS():             
                        return https://free.currconv.com/api/v7/convert?q=USD_TZS&compact=ultra&apiKey=???
                  
                    def TZSUSD()
                        return https://free.currconv.com/api/v7/convert?q=TZS_USD&compact=ultra&apiKey=???



hapo juu mfano kwa python

nikiandika
Python: 
Currencies.Exchange.Rates.USDTZS()

najua nitapata echange rate ya dola kwa sh za kitanzania labda return USDTZS ni 2318.000080
 
Uki-code labda django decorator

Python: 
from functools import wraps
from django.shortcuts import redirect

def UnauthenticatedUser(view_func):
    @wraps(view_func)
    def wrapper_func(request, *args, **kwargs):
        if request.user.is_authenticated:
            return redirect('home')
        else:
            return view_func(request, *args, **kwargs)
    return wrapper_func



Python: 
@UnauthenticatedUser
def Register(request):
    form = UserRegistrationForm()
    return ...
 
Hehehe, Tatizo la hili mkuu ni kwamba, project yako anaweza kuja mtu mwingine kuiongezea features au kui repair kitu fulani. Hapo ndio shida inapoanza mfano ukiita variable ya price madafu mtu ataangaika sana kufahamu ina maana gani.
Jinsi nzuri ya kuandika variable kwa mimi ninavyoona bora uandike hata ndefu lakini iwe descriptive. Tukirudi kwenye mfano wa password; userPassword, passwordOfTheUser, password_of_the_user. priceOfTheItemSelected. E.t.c.
 

Shukrani
 
Mm huwa naweka "pwd" huwa ni rhisi na ina herufi chache
 
Kuna documentation ,
 

Okay that's true, unafanyaje marekebisho bila rejea ya documentation,

Au unataka wapachika jina la IT wa bongo bure.
