मेरी स्ट्रिंग कुछ ऐसा है 

  var query = "@id" = 4 OR @ आईडी2 & lt; 6 और @ id3 & gt; = 5 और @name = foo "

अब मैं इस स्ट्रिंग के साथ क्या करना चाहूँगा हर" समानता "परीक्षा को उलट करना है प्रतिलिपि '> =' द्वारा '& lt;' , '& Lt;' '' = 'और' = 'द्वारा'! = 'तक!

परिणाम मुझे चाहिए: 

  var reverseQuery = "@id & lt; 4 OR @ id2 & gt; = 6 और @ आईडी3 & lt; 5 और @नाम! = Foo "

हम इसका उपयोग नहीं कर सकते हैं: 

  रिवर्स क्वैरीई = क्वेरी। स्थान (/ & gt; = / g," & lt; ")।

क्योंकि इसका परिणाम 

  @id> = 4 OR @ id2 होगा  & Gt; = 6 और @ आईडी3 & gt; = 5 और @नाम! = Foo

ठीक है? तो यह कैसे अच्छी तरह से करना है?

धन्यवाद,

एक ही स्थान का उपयोग करें कॉलबैक फ़ंक्शन जो प्रतिस्थापन निर्धारित करता है। 

  query = query.replace (/ (& lt; =? | & Gt; = | | = | & lt; & gt; |! = =) / जी, फ़ंक्शन (एम) {स्विच (एम) {केस 'और लेफ्टिनेंट;: वापसी' & gt; = '; मामले' & gt; ': वापसी' & lt; = '; मामले' & lt; = ': return' & gt; '; case' & Gt; = ': वापसी' & lt; '; case' = ': return'! = '; Case' & lt; & gt; ': return' = '; case'! = ': Return' = ';}}});

डेमो:

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...
