c++ - Using boost::ref to indicate intention in coding conventions -


When a function takes a non-conference riff as a logic, it can make a hard-to-read code Because on the calling site it is not clear what input can be changed for example, for example 

  zero function (int input, int * output) instead of those pointers applied Have to lead some code conferences; Int input = 1, output = 0; Funk (input, and output);   
 instead of  
  zero function (int input, int and output); Int input = 1, output = 0; Funk (input, output);   
 Personally, I hate using the pointers because I need to check the null. It is surprising to me that to promote: Riff (or CT + :: 11 for std :: ref) can be used to indicate intent:  
  Void func (int input, int & amp;; output); Int input = 1, output = 0; Funk (input, boost :: ref (output));   
 This will be used as the company coding conference.  My question is, is there any reason why it would not be a good idea?    
 
 
 This is not a bad idea, but it's not really implemented (as Piorranez notes). It is effectively just a comment.  
 We can do better though:  
  template & lt; Typename T & gt; Class Output_argent {public: template & lt; Typename u & gt; Friend's output_gangement & lt; U & gt; Outside (U & amp; re;); T & amp; Get () const {return MRF; } Operator T & amp; () Const {return find (); } Private: Clear Output_Certement (T & amp): MRF (RF) {} Output_Argument & amp; Operator = (console output_arugment & amp;); // not defined T & amp; MRef; }; Template & lt; Typename u & gt; Output_argument & lt; U & gt; Out (U & amp; Ref) {Return Output_Argument & lt; U & gt; (Referee); }   
 give:  
  zero foo (int x, output_argument & lt; float & gt; f) {int i = static_cast & lt; Int & gt; (F); F.get () = Static_cast & lt; Float & gt; (I + x); } Int main () {float f = 5.0f; // failed: foo (1, f); Fu (1, outside (f)); }   
 But generally these types of utilities are not required, because the name of the function should be argued what is happening with the argument:  swap (x, y)  Modification is quite clearly debated! And returning values ​​should be done with the return type, this utility can be used to limit further cases.

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...
