php - Active Record must have domain logic? -


i started time working yii framework , saw things "do not let me sleep." here talk doubts how yii users use active record.

i saw many people add business rules of application directly in active record, same generated gii. believe misinterpretation of active record , violation of srp.

early on, srp easier apply. activerecord classes handle persistence, associations , not else. bit-by-bit, grow. objects inherently responsible persistence become de facto owner of business logic well. , year or 2 later have user class on 500 lines of code, , hundreds of methods in it’s public interface. callback hell ensues.

when talked people , view criticized. when asked:

and when need regenerate active record full of business rules through gii do? rewrite? copy , paste? that's great, congratulations!

got answer, silence.

so, i:

what doing in order reach little better architecture generate active records in folder /ar. , inside /models folder add domain model.

by way, domain model owns business rules, , domain model uses active records persist , retrieve data, , data model.

what think of approach? if i'm wrong somewhere, please tell me why before criticizing harshly.

some of comments on article quite helpful: http://blog.codeclimate.com/blog/2012/10/17/7-ways-to-decompose-fat-activerecord-models/

in particular, idea models should grow out of strictly 'fat model' setup need more seems quite wise.

are having issues or trying plan ahead? may hard plan ahead , may need refactoring go ...

edit:

regarding moveusertogroup (in comment below), see how having might bother you. found thinking question: https://gist.github.com/justinko/2838490 equivalent setup might use moveusertogroup cformmodel subclass. it'll give ability validations, etc, more specific you're trying handle (and use multiple ar objects achieve objectives instead of one).

i use cformmodel handle forms have multiple ar objects or forms want other things.

sounds may you're after. more details available here: http://www.yiiframework.com/doc/guide/1.1/en/form.overview
