Rails - HABTM association, checking exists? of any object in array -


I want to see the existence of any HAABT connection in an array and if someone is present then want to return the truth.

Currently, the only way I can do this is to: 

  result = wrong [1,2,3,4]. I If user.parents.exists? (I) Results = End of True Break End

I tried to pass in an array like this, but I get an exception 

  Result = Right if user.parents.exists? ([1,2,3,4]) Include the undefined method for NoMethodError: 1? `: Fixnum

Is there a better way to do this? 

  [1,2,3,4] Injection (wrong) {| Res, i | Res || = User.parents.exists? (I)}

Too much the same logic, using Syntax Inject just more ruby-ish code.

Update:

Not tested it but it can also work: 

  user.parents .exists? (: Id => [1,2,3,4])

mongodb - CakePHP paginator ignoring order, but only for certain values -

While pagging my user model in kppp, I can sort with some values, but not others. For example, I can order results from created or email , for example, but username or reputation seems to come back order by arbitrary command for example with a list of users: $ this-> paginate = array ('condition' => array ( 'User.is_active' = & gt; true), 'border' => 24, 'order' => array ('User.created' => DESC)); Works as expected, but $ this - & gt; Paged = array ('conditions' = & gt; array (' user.isIactive '= & gt; true),' border '= & gt; 24,' command '= & gt; array (' user repeats' = ' & Gt; DESC ')); No, no. I first thought that this could be a database issue, but when I search the database directly, sorted as expected. Note: I am using Mangodebi with the Mongo DB plugin of Ichikawa for the KPPHP; Pagnetizing users are used to work properl...
