Propagating c++ exception to cython - python exception -


मुझे Cython 0.17.1 के साथ समस्या है

मेरा फ़ंक्शन एक std :: Runtime_error अगर कोई फ़ाइल मौजूद नहीं है, तो मैं इस अपवाद को अपने तरीके से मेरे सिथॉन कोड में प्रसारित करना चाहता हूं। 

  शून्य लोडफाइल (कॉन्स्ट स्ट्रिंग और फाइलनाम) {/ / कुछ कोड, यदि फ़ाइल नाम मौजूद नहीं है तो std :: runtime_error (std :: string ("फ़ाइल मौजूद नहीं है") मौजूद है); }   
 और फ़ंक्शन के सही लपेटन के बाद Cython से:  
  प्रयास करें: रनफ़ाइल (myfilename) रनटाइम को छोड़कर: प्रिंट "फ़ाइल लोड नहीं किया जा सकता"   
 लेकिन इस अपवाद को हमेशा नजरअंदाज किया जाता है, मैं पायथन से c ++ अपवाद कैसे प्राप्त कर सकता हूं?   
 
 
 क्या आप extern के साथ अपवाद हैंडलिंग घोषित कर रहे हैं? आपको सी + + अपवाद हैंडलिंग के बारे में पढ़ना चाहिए:  
 असल में, आपको निम्न की तरह कुछ करना होगा:  
  cdef extern से "some_file.h": cdef int foo () +     को छोड़कर

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...
