php - persist() and flush() inside loop - Doctrine -


i want know how many times ff: codes make roundway trip database.

foreach ($recipients $recipient) {     $received_email = new receivedemail();     $received_email->setrecipient($recipient);     $received_email->setemail($email);      $entitymanager->persist($received_email);     $entitymanager->flush();  }

$recipients array of user objects one-to-many relationship receivedemail

$email object one-to-many relationship receivedemail.

if instance $recipients has 5 entities, loop generates total of 5 trips database? or one?

is above example optimized way insert new receivedemail records?

thanks

there generated 1 insert statement each persist.

what more, can display yours sql statements debug, configure doctrine logging: https://stackoverflow.com/a/4585421/1815881

in case:

$entitymanager->getconfiguration()->                 setsqllogger(new \doctrine\dbal\logging\echosqllogger());

for many inserts should consider batch prcessing:

hope have revealed problem.

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
