ruby on rails - Not all member routes get an id in the querystring -

-

some member routes specific names not added expected :id inside query string. these routes:

resources :tests   member     :foo   end end  resources :contacts   member     :foo   end end   resource :tasks   member     :foo   end end  resource :fruits   member     :foo   end end  resource :cars   member     :foo   end end  resources :appointments   member     :foo   end end

produces this:

           foo_test          /tests/:id/foo(.:format)                   tests#foo         foo_contact          /contacts/:id/foo(.:format)                contacts#foo           foo_tasks          /tasks/foo(.:format)                       tasks#foo          foo_fruits          /fruits/foo(.:format)                      fruits#foo            foo_cars          /cars/foo(.:format)                        cars#foo     foo_appointment          /appointments/:id/foo(.:format)            appointments#foo

tasks, fruits , cars not have id. why that?

your problem in resource (singular) vs resources (plural). notice everytime have :id in route (test, contact, appointments) declared using resources , otherwise using resource.

by using resource (singular) implicitly saying have 1 resource of type there no need , id, that's why it's not present here.

you can find more infos here : difference between resource , resources methods

Deploying Qt Application on Android is really slow? -

-
as may know there 3 ways deploy qt application on android : use ministro service install qt deploy local qt libraries temporary directory bundle qt libraries in apk the first method takes 30 seconds , needs install apk . ministro . second takes 1 minute me ! , anytime try run program qt creator pushes qt libraries device. third 1 makes .apk file big , again takes 1 minute me. think situation that's not reasonable develop android application using qt. there way make deploying process faster? almost full year since op , things have not changed @ all. deployment of 7 mb apk takes on minute , half project compiles in 5 seconds. reason answering not problem got resolved, offer alternative solution. i've implemented "workaround" consisting of 2 applications work in tandem - 1 on pc , 1 on device - created compile files remotely, turned out faster alternative deployment well. on host create application launches compilation in separate process, when do...
