Retrieve posts with their latest comment in CakePHP -

-

say have model post , model comment related follows:

post hasmany comment  comment belongsto post

how use find('all') retrieve every post associated latest comment?

i have tried defining hasone relationship in post as:

var $hasone = array('latestcomment' => array('classname' => 'comment', 'order' => 'latestcomment.created desc'));

but when post->find('all') returns every post multiple times, once per each comment, latestcomment set different comments.

you can add 'limit' => 1 array of parameters return 1 comment.

alternatively, instead of defining relationship, can limit number of comments returned when perform find, using containable behaviour.

$this->post->find('all',array(                      'contain' => array(                           'comment' => array(                               'order' => 'comment.created desc',                               'limit' => 1                           )                       )                   );

this useful if want filter related sets without defining relationships - author, or within date range, example.

make sure add containable behaviour model reference.

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.
