mysql - Strange error "A new entity was found through the relationship" in Symfony on production environment -

-

i have strange error doctrine common error:

critical: uncaught php exception doctrine\orm\orminvalidargumentexception: "a new entity found through relationship 'isc\corebundle\entity\orders#ordersproducts' not configured cascade persist operations entity: isc\corebundle\entity\ordersproducts@000000000888648200000000198a79af

strangeless in error frequency. can handle 5000 orders programming code , working good. 5001st order generate error, , not save ordersproducts.

i googled solution, found (like doctrine - new entity found through relationship, https://groups.google.com/forum/#!topic/doctrine-user/bdy1qgm4tu4, etc) doensn`t me.

also, error occuring on production environment working lot of servers. on developer environment 1 server working good.

in logs looks (user has 1 session id):

  • www1 - visited product page
  • www1 - added product1 in cart
  • www2 - added product2 in cart
  • www7 - visited cart
  • www2 - choosed payment paypal
  • www2 - initialized order (and saved in db orderproducts)
  • www4 - send data paypal , redirect user payment
  • www3 - request paypal payment - trying update order , orderproducts - exceptions generated here

does got before similar problem doctrina? due using few servers?

programming code "good" orders , "bad" identical

p.s. php5.4; symfony2; mysql

if error occur on production server , not on others, think have different version of mysql on production server.

if have same mysql version on each server, try composer update on production server, , then, on development servers.

but, must resolve problem. error said new entity found through order#ordersproduct .

to solve error, have 2 solutions :

1) - persist new entity in action using : $em->persist($thecreatedentity)

2) - add cascade={"persist"} in mapping of entity (child or parent, don't know relation using).

this should solve problem element n°5001, , prevent error 5000 previous elements.

see doctrine - working associations

i'm trying apply flex button on firefox i'm having problem on chrome doesn't happens. this css: .button { display: inline-flex; align-items: center; } as can see in fiddle, "caret" word moved new line, happens if element <button> tag, <div> works expected. http://codepen.io/anon/pen/xblmgx is firefox bug or there css i'm missing? nevermind, looks "mr firefox" doesn't idea... <button> not implementable (by browsers) in pure css, bit of black box, perspective of css. means don't react in same way e.g. <div> would. this isn't specific flexbox -- e.g. don't render scrollbars if put "overflow:scroll" on button, , don't render table if put "display:table" on it. stepping further, isn't specific <button> . consider <fieldset> , <table> have special rendering behavior: data:text/html,<fieldset style="d
