How to test routes added by a Rails Controller Concern -


i trying test routes added controller via concern. want write acceptance tests include concern's routes in controller in order avoid regressions document concern's use cases. make sense? if so, how 1 go accessing routes added controller via concern in tests?

following stripped down version of app's routes. permissionable concern routes work expected when running app.

#routes.rb routes.draw   concern :permissionable     member       'permission', action: "permission_show"      end   end    resources :profiles, concerns: :permissionable end

and stripped down version of controller concern, included profilescontroller

module permissionactions   extend activesupport::concern    def permission_show     if current_user.admin?       render :text => "you have permissions entity"     end     render :text => "no permission entity"   end     def test_a_thing       "test"   end end

finally, answers in question, rspec examples this.

describe applicationcontroller, type: :controller   controller     include permissionactions      def index; end   end    describe 'a controller permission actions'     'can call method'       expect(@controller.test_a_thing()).to eq("test")     end      'exposes permission route'       :permission     end   end end

the first example works, second example complains no route matches {:action=>"permission", :controller=>"anonymous"}

i tried many things list of them here, solution thought work sure re-draw routes inside test this:

... 'exposes permission route'   routes.draw {     concern :permissionable       member         'permission', action: "permission_show"       end     end     resources :anonymous, concerns: :permissionable   }    # response = @controller.permission_show()   :permission, :id => "anyid"    expect(response).to have_http_status(200) end

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m...

sql server - Why does Linq-to-SQL add unnecessary COUNT()? -

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
