ruby - How is the easiest way to sum 2 disjoint sets of Mongo documents from different databases? -


I have similar documents in two separate databases . I want to connect the documents with both the DBS. How to do the easiest? I need the amount of these sets, the sets are different

I think using Mongoimport, Mongorostor but how do you suggest to deal with the problem?

I want to do it with Mongodp, yes. 

  mongodump -d dbA

Some code from dump / dba . Now run these commands for import into another DB. 

  mongorestore -d dbb dump / dbA

For more information on its parameters, you mongorestore --help .

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.
