ruby on rails - How do you add an item into an array if passes the logical statement? -


मैं मौजूदा सरणी A A_array पर आधारित एक नया सरणी B_array बनाना चाहूंगा । यदि उस मद में A_array में कोई निश्चित फ़ील्ड है तो उसे B_array में जोड़ें। वर्तमान में यह मेरे पास है और यह सब कुछ में डाल रहा है बी_अरे : 

  बी_अरे = ए_अरे.मैप {| आइटम | अगर item.name == 'जोश'}   
 ए_अरे:  
  [आईडी: 0, नाम: "जोश", ईमेल: "जोश @ जॉश @ Gmail.com "], [आईडी: 1, नाम:" स्कॉट ", ईमेल:" स्कॉट @ जोश @ जीमेल डॉट कॉम "], [आईडी: 2, नाम:" जोश ", ईमेल:" डान @ जोश @ जीमेल  :  
  [id: 0, नाम: "जोश", ईमेल: "जोश @ josh@gmail.com"], [आईडी: 2, नाम: "जोश", ईमेल: "dan @ josh@gmail.com"]   
 धन्यवाद!   
 
 
 उपयोग करें:  
  a = [{id: 0, नाम: "जोश ", ईमेल:" जोश @ josh@gmail.com "}, आईडी: 1, नाम:" स्कॉट ", ईमेल:" scott @ josh @ gmail.com "}] b = a.select {| i | मैं [: नाम] == 'जोश'}   
 आपके द्वारा दी गई शर्त के आधार पर फ़िल्टर करेगा और परीक्षणों को पास करने वाले तत्वों की सरणी वापस करेगा।

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. I am using Python 2.7.8 and the version of SQLAlchemy module is 0.9.8. By the way, using a project flask- SQLAlchemy, it works well, I'm confused.

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...
