i have route: pfs_platform_home: path: /{page}/{reset} defaults: { _controller: pfsplatformbundle:advert:index, page: 1, reset: true } requirements: page: \d* reset: true|false if use link without specifying reset , router uses default value , in indexaction, reset parameter automatically converted boolean true . i.e.: <li><a href="{{ path('pfs_platform_home') }}">inicio</a></li> but when that, time $reset appears string 'false' in indexaction, not boolean: <a href="{{ path('pfs_platform_home', {'page': p, 'reset': 'false'}) }}">{{ p }}</a> what missing? url paths , parameters strings. if have url like http://example.com/page/true?foo=2&bar=false the server cannot know true should interpreted boolean, while foo supposed integer , bar supposed boolean, too. if want process url parameters, pass , treat them strings. later, can vali...

this question similar to: xcode run tests (even disabled ones) but different in i'm not disabling tests. i'm pressing single test icon next test function or test case: a friend of mine running kif in swift project , has no problem this. i'm guessing it's setup: i have main xcworkspace file contains main target, unit tests target, , automated tests target (which contains kif tests). workspace has pods project, using frameworks. that's it. here's scheme setup: i've experienced issue in released versions of xcode 6. edit i found workaround time being. you have modify each of test classes (white space changes fine). trigger xcode index files , recognize tests , test cases , generate symbols & icons them in test navigator. (it's recommended delete derived data first remove "ghost tests".) if don't each test case class, unrecognized test case classes run, if select 1 test run. once force xcode recognize test class...

i want implement user event tracking in website statistics etc. thought creating table called tracking_events contain following fields: | id (int, primart) | | event_type (int) | | user_id (int) | | date_happened (timestamp)| this table contain large amount of rows (let's assume @ least every page view tracked event , there 1,000 daily visitors site). is practice create table event_type field differentiate between different, yet identically structured rows? or better idea make separate table each type ? e.g.: table pageview_events | id (int, primart) | | user_id (int) | | date_happened (timestamp)| table share_events | id (int, primart) | | user_id (int) | | date_happened (timestamp)| and on 5-10 tables. (the main concern performance when selecting rows where event_type = ... ) thanks. it depends. if need have them separated, because querying them separately, splitting them 2 tables should fine. saves having store discriminator column. but....

if have 2 string objects both have value "hi", , add them nsmutableset, treated different objects or not? bunch! beside correct comment of @rmaddy, there fundamental problem it: impossible guarantee no objects equal in set. (it easy guarantee not identical.) imply recheck equaty of objects (expensive), when 1 changes (mostly impossible detect). is, because nsset not copy content objects. let's have example: nsmutablestring *first = [@"amin" mutablecopy]; nsmutablestring *second = [@"amin negm" mutablecopy]; nsset *set = [nsset setwithobjects:first, second]; [first appendstring:@" negm"]; both objects equal than, none removed.

consider code: <script>var foo = 'bar';</script> <div id='isolated'> <script>console.log(foo)</script> </div> this return 'bar' console. i'd foo , other variables declared outside #isolated undefined within it. how can achieved? cross-browser, lightweight , native solution preferable. that's not how javascript works. doesn't scope because of html element block. you're declaring foo @ global scope, declare in scope used when needed. using es6 (harmony), using let instead of var (proposed, not supported) declare variable proposes block level variable instead of global scoped variable. as stands however, javascript has no idea foo being logged inside isolated div unless use logic.
