c# - Register multiple DbContext for IUnitOfWork using Unity IOC -


i using repository pattern unit of work using iunitofwork via

https://github.com/ziyasal-archive/repositoryt.entityframework/tree/master/repositoryt.entityframework

sample ioc registration given under https://github.com/ziyasal-archive/repositoryt.entityframework/blob/master/repositoryt.entityframework.autofacconsolesample/ioc.cs

when have multiple dbcontext in project , need register iunitofwork how can correct registration ioc? seems pick last registration example

        container.registertype<iunitofwork, efunitofwork<sample1datacontext>>(new containercontrolledlifetimemanager());         container.registertype<iunitofwork, efunitofwork<sample2datacontext>>(new containercontrolledlifetimemanager());

when resolve return me sample2datacontext

https://github.com/ziyasal-archive/repositoryt.entityframework/issues/11

unity let have 1 "default" mapping. if wish map 1 "from" type (iunitofwork) multiple "to" types (efunitofwork<sample1datacontext>, efunitofwork<sample2datacontext>, ...) need use named registrations.

container.registertype<iunitofwork, efunitofwork<sample1datacontext>>(     typeof(sample1datacontext).name, new containercontrolledlifetimemanager()); container.registertype<iunitofwork, efunitofwork<sample2datacontext>>(     typeof(sample2datacontext).name, new containercontrolledlifetimemanager());

in case i'm using typeof(sample1datacontext).name name of registration.

then when resolving, name of registration need used resolve desired concrete type. example retrieve efunitofwork<sample1datacontext>:

container.resolve<iunitofwork>(typeof(sample1datacontext).name);

usually iunitofwork dependency type such service. example register interface iservice maps concrete service , dependent on iunitofwork , wish use efunitofwork<sample2datacontext> type register similar to:

container.registertype<iservice, service>(     new injectionconstructor(         new resolvedparameter<iunitofwork>(typeof(sample2datacontext).name)));

if need inject multiple iunitofwork instances 1 service add appropriate parameters injectionconstructor. if constructor service service(iunitofwork data1context, iunitofwork data2context) this:

container.registertype<iservice, service>(     new injectionconstructor(         new resolvedparameter<iunitofwork>(typeof(sample1datacontext).name)),         new resolvedparameter<iunitofwork>(typeof(sample2datacontext).name)));

just wondering if guys can code. it works serving images not pdf brochure. in advance func main(){ http.handlefunc("/", func(w http.responsewriter, r *http.request){ filename := "/var/www/filedipenser/brochure.pdf" streampdfbytes, err := ioutil.readfile( filename ) if err != nil { fmt.println(err) os.exit(1) } b := bytes.newbuffer(streampdfbytes) w.header().set("content-type", "application/pdf") if _, err := b.writeto(w); err != nil { fmt.fprintf(w, "%s", err) } w.write([]byte("pdf generated")) }) err := http.listenandserve(":4111", nil) if err != nil { log.fatal("listenandserve: ", err) fmt.println(err) } } the code bit inefficient appears working. however, pdf viewers might sensitive extraneous output adding end of http response stream...

python - Best design pattern for collection of objects -

i have following architecture: +-----------------+ | collection | | | | | | | | | +-----------------+ | ^ | | create() | | | | v | getitem(b) +------------+ | | item | | | | | | +------+ | | +------------+ a class managing collection of items, creates items. , these items may need other items collection. the actual code in python, , collection passes parameter created item . see it, bad practice. improvement can see pass few functions of collection needed item , instead of whole instance. for example: class collection: getitem(self, id): ... createitem(self, id): item = item(id, self) # <-- pass self ... class item: __init__(self, id, col): ... col.getite...
