java - Should unnecessary elses be kept? -


अगर मेरे पास कोड का एक सरल हिस्सा है: 

  सार्वजनिक शून्य ट्रेसपैथ () { Int चरण = 0; चरण = बीएफएस (); If (steps == 0) {pathFound (false); System.exit (0); } और {System.out.println (चरण); pathFound (सही); System.exit (0); एपीएआईके यह  और  के रूप में  
  सार्वजनिक शून्य ट्रेसपैथ () {int steps = 0; के बिना rewriten हो सकता है; चरण = बीएफएस (); If (steps == 0) {pathFound (false); System.exit (0); } System.out.println (चरण); pathFound (सही); System.exit (0); }   
 क्या कोई प्रदर्शन (या अन्य तार्किक) कारण ऐसा  और  को रखने (या हार) है? या यह सिर्फ (इस उदाहरण में) शैलीगत पसंद है?   
 
 
 इस स्थिति में यह शैलीगत वरीयता है क्योंकि आप अगर बयान के अंत में बाहर निकलें यदि आपके पास सिस्टम के पास नहीं था, तो एक्सट (0) के अंत में, दूसरे उदाहरण में आप कोड के दोनों टुकड़े निष्पादित करेंगे।

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...
