Rails 3: wrapping ActiveRecord operations and external credit card in a single transaction -


I am using ActiveMerchant to process a credit card transaction that can be successful or unsuccessful, which Part of some transactions, if any part of the internal accounting using activivercard processing fails, then I am not clear about how to roll back the whole transaction.

I have a payment model, and a point model - the user's digits are converted into dollars to reduce their payments.

  • Save points transactions: Debit user accounts, credit internal accounts
  • Save credit card transactions results ( Whether it succeeds or fails)
  • Again, if everything works, send an email to the user

    I see how it works And believe that I callback to handle the contents like email to the user after after_commit (and after_rollback ).

    But how can I make an unsuccessful credit card transaction as a similar rollback, which is a failed AR save reason? Is it as easy as coding like increase active activation: rollback if my non-AR transaction fails? The above document contains a section that bothers me about it (related to transactions that do not work in many database connections).

    Rail 3.2.5, MySQL 5.1 (Indobi), Ruby 1.9.3

    < P> Your ActiveMerchant call is on an external server so it will not affect your ActiveRecord transaction. ActiveRecord :: Rollback . Feel free to increase

    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...
