mysql - Datamapper ORM- Codeigniter Advance Relationship -


please me understand basic use of datamapper's include_join_fields function. tried lots of not getting results.

i have application $object->include_join_fields()

i have user table , country table.

please me set $hasone=array('country_id'); relation

i haven't idea all, not getting exact point after reading documentation of include_join_fields

any appricate

thanks

include_join_fields many many relationships, have countries_users pivot table, , users belong many country.

for example, take 1 user, , countries, belongs to. store, how user related country. have store extra field in pivot table: countries_users.

so pivot table, countries_users this, example field is_he_working_there:

id country_id user_id is_he_working_there

when make query user's countries, datamapper won't add field default. , here comes include_join_field(), if call that, datamapper add field end result.

but hasone, won't take effect, because user, , other table fields also. no pivot table here, don't need include_join_fields()

javascript - Why does running this loop 9 times take 100x longer than running it 8 times? -

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
