- Where Developers Learn, Share, & Build Careers


I am currently rewriting a python GAE app in Java, and ask about my unit design . I have entities like the following, so that I ask the datastore and can easily return a unique list of designers:

class designer

  • name: string <

If the designer gets rid of the class then the code will be very easy to wrap a string, but I get the list of gene designers to SELECT DISTINCT Designer Can not Do from Gene Is, or is there any other way?

GAE does not support complex queries like SQL (datastore-billet) SQL, The model (DB) structure must be designed as you explained earlier.

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.

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...
