ruby on rails - Complex sorting on association in rails3 -

-

i have 3 model hotel, package, packageprice, , association like:

hotel can have many packages , each package has 1 packageprice

models are:

class hotel < activerecord::base   attr_accessor :excel_sheet, :excel_sheet_file_name   attr_accessible :hotel_name, :stars, :location, :searchable, :excel_sheet, :excel_sheet_file_name    has_many :package_prices, :dependent => :destroy   has_many :packages, :through => :package_prices, :order => 'package_prices.price' end   class package < activerecord::base   attr_accessible :package_name   has_many :package_prices, :dependent => :destroy, :order => 'price desc'   has_many :hotels, :through => :package_prices, :order => 'package.package_prices.price' end  class packageprice < activerecord::base   attr_accessible :price, :package_id, :hotel_id   belongs_to :package   belongs_to :hotel end

and corresponding tables are:

mysql> desc hotels     -> ; +------------+--------------+------+-----+---------+----------------+ | field      | type         | null | key | default |          | +------------+--------------+------+-----+---------+----------------+ | id         | int(11)      | no   | pri | null    | auto_increment | | hotel_name | varchar(255) | yes  |     | null    |                | | stars      | varchar(255) | yes  |     | null    |                | | location   | varchar(255) | yes  |     | null    |                | | created_at | datetime     | no   |     | null    |                | | updated_at | datetime     | no   |     | null    |                | | searchable | tinyint(1)   | yes  |     | 1       |                | +------------+--------------+------+-----+---------+----------------+ 7 rows in set (0.00 sec)  mysql> desc packages; +--------------+--------------+------+-----+---------+----------------+ | field        | type         | null | key | default |          | +--------------+--------------+------+-----+---------+----------------+ | id           | int(11)      | no   | pri | null    | auto_increment | | package_name | varchar(255) | yes  |     | null    |                | | created_at   | datetime     | no   |     | null    |                | | updated_at   | datetime     | no   |     | null    |                | +--------------+--------------+------+-----+---------+----------------+ 4 rows in set (0.00 sec)  mysql> desc package_prices; +------------+----------+------+-----+---------+----------------+ | field      | type     | null | key | default |          | +------------+----------+------+-----+---------+----------------+ | id         | int(11)  | no   | pri | null    | auto_increment | | package_id | int(11)  | yes  |     | null    |                | | price      | int(11)  | yes  |     | null    |                | | created_at | datetime | no   |     | null    |                | | updated_at | datetime | no   |     | null    |                | | hotel_id   | int(11)  | yes  |     | null    |                | +------------+----------+------+-----+---------+----------------+

and have hotels records in variable @hotels , want filter @hotels price in asc or desc order. please me find out query.

you using this,

@hotels = hotel.joins(:package_prices).order('package_prices.price')

however don't think models set way described, i'm not sure if want

java - Copying object fields -

what best way of copying classes when need have 2 independent variables? have simple class: public class myclass { boolean = false; string b= "not empty"; } do need make method : assign(myclass data ) { a= data.a; b= data.b; } is there automatic method copy (duplicate) objects in java? do need make method : pretty close. instead of making method, should make constructor. such constructors called copy constructor , , create them this: myclass(myclass data) { = data.a; b = data.b; } and create copy of instance, use constructor this: myclass obj1 = new myclass(); myclass obj2 = new myclass(obj1); copy constructor can tedious : using copy constructor create deep-copy can tedious, when class has mutable fields. in case, assignment create copy of reference, , not object itself. have create copy of fields (if want deep copy). can go recursive. a better way create deep copy serialize , deserialize object. why not use clone()? ...

i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.
