jquery - Selecting .not(this) not working -


I have a few select lists which are all the same content, I want to be when one option is selected in one It will be disabled in others. 

  & lt; Div class = "social-option" & gt; & Lt; Gt selection and; & Lt; Option selected = "selected" value = "facebook" & gt; Facebook & lt; / Option & gt; & Lt; Option value = "0" & ​​gt; & Lt; / Options & gt; & Lt; Option value = "Twitter" & gt; Twitter & lt; / Option & gt; & Lt ;! - If I choose it - & gt; & Lt; Option value = "linked" & gt; Linked & lt; / Options & gt; & Lt; Option value = "Instagram" & gt; Instagram & lt; / Option & gt; & Lt; Option value = "Flickr" & gt; Flickr & lt; / Options & gt; & Lt; / Select & gt; & Lt; / Div & gt; & Lt; Div class = "social-choice" & gt; & Lt; Gt selection and; & Lt; Option selected = "selected" value = "facebook" & gt; Facebook & lt; / Option & gt; & Lt; Option value = "0" & ​​gt; & Lt; / Options & gt; & Lt; Option value = "Twitter" & gt; Twitter & lt; / Option & gt; & Lt ;! - Then it is disabled - & gt; & Lt; Option value = "linked" & gt; Linked & lt; / Options & gt; & Lt; Option value = "Instagram" & gt; Instagram & lt; / Option & gt; & Lt; Option value = "Flickr" & gt; Flickr & lt; / Options & gt; & Lt; / Select & gt; & Lt; / Div & gt; & Lt; Div class = "social-choice" & gt; & Lt; Gt selection and; & Lt; Option selected = "selected" value = "facebook" & gt; Facebook & lt; / Option & gt; & Lt; Option value = "0" & ​​gt; & Lt; / Options & gt; & Lt; Option value = "Twitter" & gt; Twitter & lt; / Options & gt; & Lt ;! - and it is also disabled - & gt; & Lt; Option value = "linked" & gt; Linked & lt; / Options & gt; & Lt; Option value = "Instagram" & gt; Instagram & lt; / Option & gt; & Lt; Option value = "Flickr" & gt; Flickr & lt; / Options & gt; & Lt; / Select & gt; & Lt; / Div & gt; Line   
 Use it:  
  $ ('Select Social Options'). ('Change', function) (var newselected = $ ('option: selected', this) .val (); var newSelectedSiblings = $ ('Select social option'). ("Option [value =" + new] Select + "]"); Newly selected siphonings (not). (Each) function () {// here .not selector which $ (this) .attr ('disabled', 'disabled');})}} } Does not work;   
 A ???? Any ideas why? Besides, when I  this :  
  Var newSelectedSiblings = $ ('' if you replace the selector, then why does not this line work. Select social option. Rin '). ("Option [value =" + new selection + "]");   
 like this:  
  var newSelectedSiblings = $ ( This code is the same as the  change  selector:  $ (the "option [value =" + new select + "]");   
 Select 'Social Options'). ('Change' ... ...   
 
 
  Update   
 I The first question has been found to have a solution: instead of    newly selected sibbings.Note (this)   
 I have used:  
  Newly selected jokes.Note ('Options: Chosen    
 
 
 I  siblings ()  I use the function. What does this make you feel like this:  
  $ (this) .siblings (). Each (function () {$ (this) .attr ('disabled', 'disabled');});   
  No ()  function is not working because jQuery is strange when it is compared:  
  $ ( This) == $ (this) // false return

I tried to create a new database in my project, but when I run the script, I get this error, I have another project, this type of definition worked before, but now it gets a single error.

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...
