How to insert value into a column with a default value? [PostgreSQL 9.1] -


मेरे पास ऐसी तालिका है: 

  बनाओ टेबल कर्मचारी (आईडी इंटेगर डिफॉल्ट नेक्सवील ('आईडी ':: रेगक्लास) नहीं है, नाम का चरित्र नहीं है, शून्य, नियोक्ता INTEGER DEFAULT (-1);   
 और मैं इस तालिका में STH सम्मिलित करना चाहता हूं (मैं  नियोक्ता  को डिफ़ॉल्ट के रूप में छोड़ना चाहता हूं -1):  
  कर्मचारी (नाम, आईडी) मूल्यों में शामिल करें ('डो', 2);   
 लेकिन मेरे पोस्टग्रेएसक्यूएल 9.1 शिकायत कर रहा है:  
  त्रुटि: तालिका "कर्मचारी" पर डालें या अपडेट विदेशी कुंजी बाधा "FK_employer" विस्तार का उल्लंघन करता है: कुंजी (नियोक्ता ) = (- 1) तालिका "नियोक्ता" में मौजूद नहीं है   
 मुझे पता है कि id = -1 के साथ कोई नियोक्ता नहीं है, लेकिन फिर भी, मैं इसे इस तरह चाहता हूं। मैं इस प्रदाता के लिए नियोक्ता को -1 के रूप में निर्धारित करना चाहता हूं। क्या यह postgreSQL के साथ संभव है?   
 
 
 डिफ़ॉल्ट नल करें क्या यह अच्छा है?  
  नियोक्ता इंटेगर डिफॉल्ट रद्द

Python SQLAlchemy：AttributeError: Neither 'Column' object nor 'Comparator' object has an attribute 'schema' -

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...
