cakephp - Cake PHP parent/child/grandchildren menus -


I want to display the menu with my children and the output of grand kids will be like this

Parents

- Children

Parents

- Children

My menu controller 

 < Code> public function buildTree ($ arr, $ parent_id = 0) {$ op = array (); Foreach ($ item as $ item) {if ($ item ['parent_id'] == $ parent_id) {$ op [$ item ['id']] = array ('name' = & gt; $ item ['name '],' Parent '= & gt; $ item [' parent_id ']); $ Children = buildtree ($ arrival, $ item ['id']); If (children) {$ from [$ item ['id']] ['parent_id'] = $ children; }}} Return $ op; }   
 My visual element app \ view \ elements \ navigation.ctp  
  and ; $ Item ['menuItem'] ['name']. "& Lt; / li & gt;"; $ Child = $ menu_items-> Buildsubmenus ($ item ['MenuItem'] ['id']); Public relations ($ child); }? & Gt; & Lt; / Ul & gt;    
 
 
 Your controller needs to pass the tree and pass it to see. How to prepare it? It depends on your application, maybe you have to call the data base, maybe it's just a constant array, etc.  
 You will need to create your own format for the tree, for example:  Child 11 [1] = & Gt; Array ([0] => Grandfather 121 [1] => Parent 122)) [1] = & gt; Parents 2 [2] => Array ([0] = & Gt; child 31))   
 Then you can pass it to see and loop the array. To do this, to create the menu, you can display the array You can use a recursive function .. or if you know that there are more than 3 If you do not have that level then you do not have to do anything with the cake. If you have a menu stored on the database, then you have 3  for  loops  
 =) Perhaps you can use DB to retrieve the menu, however you still have to pass it to see the function to display it  
 Hope it helps

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...
