Hello, I have a strange bug. I launch a PHP Unit test Suite. At the beginning, it executes a big query to initialize the database. If I put a breakpoint just after the execution of the sql, there is no problem and my tests pass. If I don't put any break point, they don't pass and say that the tables don't exist! It works as if the s...

Say you for example had the two following classes that you want to work with: User ˪ Id ˪ Name ˪ Password Employee : User ˪ Pay How would you store those in a MySQL...

I have a table which captures which user visited which store. Every time a user visits a store, a row is inserted into this table. Some of the fields are shopping_id (primary key) store_id us...

If a model changes an attribute locally, then changes it back, ActiveRecord doesn't send the change to the DB. This is great for performance, but if something else changes the database, and I want to revert it to the original value, the change doesn't take: model = Model.find(1) model.update_attribute(:a, 1) # start it off at 1 # some ...

I'd like to paginate through a randomly sorted list of ActiveRecord models (rows from MySQL database). However, this randomization needs to persist on a per-session basis, so that other people that visit the website also receive a random, paginate-able list of records. Let's say there are enough entities (tens of thousands) that storin...

Also tried RE...
