Hi everybody,
the other day, I thought it may be useful to have a .sync() method on ActiveRecord objects. The behavior would be something between a .reload() and a .save().
- At every reload, an internal hash would store the attributes as they were in the db at reload time (think svn's working-base) - whenever attributes are changed on the object, the values of that hash would remain untouched - whenever sync is called, the tuple gets reloaded from the db and both the current db tuple and the current object attribute values are compared to the working-base hash. if changes were made on the object, they get populated to the db and vice versa. - conflicts could result in exceptions or there could be defaults like so: my_object.sync :on_conflict_follow => :database
I didn't have time to implement this so far, but I wanted to share this idea and get feedback. What do you think?
