Ruby (Rails) DRY - Function pattern

I'm using ruby on rails for a project and noticed I'm using some pattern on my functions that goes like this:

begin
    ActiveRecord::Base.transaction do
        #some database manipulation
    end
    return true
rescue
    return false
end

So I would like to DRY my code, in a way that only that #some database manipulation is gonna change. Any ideas of how I could do that? Thanks in advance!

You could create a method like this:

def with_transaction
  ActiveRecord::Base.transaction do
    yield
  end
  return true
rescue 
  return false
end

And then use it like:

with_transaction do 
  # some db manipulation
end

But generally I would advise against silencing errors like that.
