symfony1 - Symfony Embedded Relation Many2Many - linking unique fields or creating new fields -

-

i'm using embedded relation allow user edit/add books library , in same form add/remove n authors wrote book within auto generated admin.

here problem: authors name unique, when enter author exists sfvalidatordoctrineunique produces error.

an object same "name" exist.

what want catch error , tell form not try add exisiting author anew.

do use event system that, or modify validators or how can that?

thank hoodie

ps: after searching found might solution haven't made work yet http://symfonyguide.wordpress.com/2009/09/28/symfony-forms-saving-process/

i opinion should not add new author if exists.

sfdoctrineactastaggableplugin same way. searches existing tags , merge them current (added user form) tags.

but here 1 issue: 2 authors - aleksander pushkin , alexander pushkin, same authors us, different machine.

c# - Is it possible to remove an existing registration from Autofac container builder? -

something along lines: builder.registertype<mytype>().as<itype>(); builder.registertype<mytype2>().as<itype>(); builder.deregistertype<mytype>().as<itype>() var container = builder.build(); var types = container.resolve<ienumerable<itype>>(); assert.istrue(types.count == 1); assert.istrue(types[0].gettype == typeof(mytype2)); scenario: go through bunch of assemblies , go register types want make sure have 1 implementation of given type. need before create container. track on own nice if autofac me bit. this cannot done directly using containerbuilder , unless start on new one. mind you, having first built container should able construct new container filtering away unwanted types , reusing registrations first container. this: ... var container = builder.build(); builder = new containerbuilder(); var components = container.componentregistry.registrations .where(cr => cr.activator.limittype != typ...

php - Mysql PK and FK char(36) vs int(10) -

-
i have read mysql can handle indexes , searches better if tables keys integers rather char(36) uuid's. is worth converting int(10)? note: use 1 server , have have plans use multiple databases concurrently therefore removing 1 of big reasons using uuid. our tables innodb if makes difference. thanks in advance. usually rdbms can handle integer keys pk more efficient, other datatypes. reason how build index column, yes: long dont require string (or other typed) keys, should use integers. however: char(36) , int(10) far away being equal, because int(10) much smaller, char(36). dont know, if require many different keys, should keep in mind. update, complete last paragraph: int(10) 32-bit, char(36) 36 - ^byte^ (= 288-bit). not mean, int consumes less space, means, char(36) has 4 times more different keys.
