i'm trying change database connection used in cakephp 3 on fly. every answer question found refers cakephp 2 ( these three for instance). this guy found solution cakephp 3 having finite number of databases, , defining database used table file. the thing want create new database every new user, , change database when logs in. can't know in advance databases exist, write in config/app.php file. and can't set default database in each /src/model/table file, because tables same in every database. use connectionmanager::config() function create connections on fly , connnectionmanager::alias() method make table classes use default. there article describing process here: http://mark-story.com/posts/view/using-cakephp-and-a-horizontally-sharded-database the difference can create connection config on fly instead of declaring shards manually shown in article.

i wondering regex in java , stumbled upon use of backslashes. instance, if wanted occurences of words "this regex" in text, this: pattern.compile("this regex"); nonetheless, this: pattern.compile("this\\sregex"); my question is: difference between 2 of them? , why have type backslash twice, mean, why isn't \s escape sequence in java? in advance! \s means whitespace character, including tab, line feed , carriage return. java string literals use \ escape special characters. put character \ in string literal, need write "\\" . regex patterns use \ escape character, , way put string literal use two, because goes through 2 separate escaping processes. if read regex pattern plain text file example, won't need double escaping.

it's been discussed here on stackoverflow ( appointment.save , appointment.update set ismeeting true ) ews has limitations on how meeting invitations can't sent automatically when creating new calendar items / meetings inside public folder. since need send meeting calendars of various attendees wondering if has ever discovered workaround strange behavior (i can't find way send meeting invitations programmatically). the thing seems working forward calendar item address of attendees, that's not option since makes meeting available attachment in email. on msdn have sample create , sends invite msdn link but not work public folders: "the reason shouldn't work because public folders don't publish free/busy information. cannot invite public folder meeting nor can see if public folder available."

my problem best explained simple code example: function dothing(a, ...b, c) { console.log(a, b, c) } dothing(1,2,3,4); // expect "1 [2,3] 4" this instead gives syntax error unexpected token , pointing comma after b in function definition. is not possible put single parameter after 'rested' parameter es6? if not, idea why? useful me. thanks! edit: thought dothing(a, ...b, c) unambiguous, see dothing(1,2,3) need arbitrary rule decide whether 3 goes in b or c (i.e. if pass number of params less or equal number of params in function definition). you should not use js keywords in function names (e.g. do ) as developer.mozilla.org site says: if last named argument of function prefixed ..., becomes array elements 0 theargs.length supplied actual arguments passed function. actually feature of es6 called rest parameters meant last in list of parameters. so code work: function do2 (a, b, ...c) { console.log(a, b, c); } do2(1,2
