When I ran the following part of the code, I encountered an error: Error: Wrong argument in #cartesian Number (X)>

;;;; Function Definition 

  (define (eps-func p) (let * ((P (forged-> Cartesian)) (x (vector 3-XP)) (y (vector 3-yp ) (Vector 3-jpp) (if (> sin (* 2 pi xyz) 0) (dielectric (epilene 12)) (dielectric (epicylon 1)))))   
 ;;;; Function call  
  (set! Default-content (content-function (content-flick eps-funk)))   
 I do not know that Where is it wrong? The above code is only part of a control file.  
 Some background information is similar to the following:  
  (lacquer-> Cartesian x)   
 Where x is a vector 3  
 
        
 3-Vector with the given components.  
  (vector3-xv) (vector3-yv) (vector3-zv)   
 Relevant components of Vector V  
 Content-Function [Function] The Function of an Argument, Position Vector 3   
 
 
 Maybe you should invite them to  (JALK-> Cartesian)) with the  parameter? Or does this function give lambda?

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...
