ruby - rails has_many :through has_many :through -

-

i'm wondering extent can use associations in rails. take consideration following:

class user < activerecord::base     has_one :provider     has_many :businesses, :through => :provider end  class provider < activerecord::base     has_many :businesses     has_many :bids, :through => :businesses     belongs_to :user end  class business < activerecord::base     has_many :bids     belongs_to :provider end  class bid < activerecord::base     belongs_to :business end

i able set these nifty shortcuts user.businesses , provider.bids doing user.bids? possible associate association, speak?

this entirely possible, needs little work. following model definitions used in conjunction nested_has_many plugin can fetch bids belonging user @user.bids

class user < activerecord::base     has_one :provider     has_many :businesses, :through => :provider     has_many :bids, :through => :businesses end  class provider < activerecord::base     has_many :businesses     has_many :bids, :through => :businesses     belongs_to :user end  class business < activerecord::base     has_many :bids     belongs_to :provider end  class bid < activerecord::base     belongs_to :business end

however getting user bid take more work.

a colleague of mine designing sql queries 1 below produce reports, displayed in excel files through external data query. @ present, reporting processes on db required (no crud operations). i trying convince him better use ruby orm in order able display data in rails/sinatra app. despite obvious advantages in displaying data, advantages there him in learning use orm sequel or datamapper? the sql queries writing quite complex, , being relatively new sql, complains time-consuming , confusing. possible write extremely complex queries orm? , if so, suitable(i have heard sequel legacy dbs)? , advantages of learning ruby , using orm versus sticking plain sql, in making complex database queries? i'm datamapper maintainer, , think complex reporting should use sql. while think someday we'll have dsl provides power , conciseness of sql, i've seen far requires write more ruby code sql complex queries. rather maintain 5 line sql query 10-15 lines of ruby code desc...

php - PHPDoc: @return void necessary? -

is necessary this: /** * ... * * @return void */ i have quite few methods don't have return value, , seems redundant put in comment. considered bad form leave out? if makes clear documentation, leave in, isn't strictly necessary. it's entirely subjective decision. personally, leave out. edit stand corrected. after little googling, wikipedia page says: @return [type description] tag should not used constructors or methods defined void return type. the phpdoc.org website says: @return datatype description @return datatype1|datatype2 description the @return tag used document return value of functions or methods. @returns alias @return support tag formats of other automatic documentors the datatype should valid php type (int, string, bool, etc), class name type of object returned, or "mixed". if want explicitly show multiple possible return types, list them pipe-delimited without spaces (e.g. "@retur...
