How can I check Rails record caching in unit tests? -

-

i'm trying make unit test ensure operations / not query database. there way can watch queries, or counter can check @ worst?

if intent discern whether or not rails (activerecord) caches queries, don't have write unit test - already exist , part of rails itself.

edit:

in case, see if adapt 1 of strategies rails team uses test activerecord itself. check following test link above:

def test_middleware_caches   mw = activerecord::querycache.new lambda { |env|     task.find 1     task.find 1     assert_equal 1, activerecord::base.connection.query_cache.length   }   mw.call({}) end

you may able following:

def check_number_of_queries   mw = activerecord::querycache.new lambda { |env|     # assuming object set perform operations     myobject.first.do_something_and_perform_side_operations     puts activerecord::base.connection.query_cache.length.to_s   } end

i haven't tried such thing, might worth investigating further. if above return number of cached queries waiting happen, should trivial change puts assert test case.

razor - Is this a bug in WebMatrix PageData? -

i think may have found bug in webmatrix's pagedata, not sure. concerns how pass data partial page calling page. in webmatrix documentation (tutorials, e.g. " 3 - creating consistent look ", , example code), pagedata recommended mechanism pass data between pages (e.g. content page layout page, or partial page). however have found not work other way, pass data partial page calling page. modifying or adding entries in pagedata in partial page, not seem calling page. cutting right down simplest possible example, in test page may have this: @{ pagedata["test"] = "initial entry"; } <p>before calling partial page, test value @pagedata["test"]</p> @renderpage("_testpartial.cshtml") <p>after returning calling page, test value @pagedata["test"]</p> and in _testpartial.cshtml page might have this: @{ pagedata["test"] = "modified entry"; } <p>in partial page...

android - layout with fragment and framelayout replaced by another fragment and framelayout -

edit: so after comments below, revisted , realized hanging me up. imagine client list , client details activity started : public class clientsmainactivity extends fragmentactivity { @override public void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); //studiotabopenhelper db; setcontentview(r.layout.main_client_activity); } } so works great, starts main_client_activity (defined in layout below, , call activity when button on main screen clicked): intent intent = new intent(getactivity(), clientsmainactivity.class); startactivity(intent); easy issue is, clientsmainactivity not call oncreateview or anything, sets layout layout defines fragment, , listfragment. fine cause not trying pass clientsmainactivity , if have hypothetical activity like: sessionmainsactivity called when click on session edit of client, not calling sessionsmainactivity same way (starts activity sets alayout), want layout set defines...
