Hey,
I have a model called Vocab with an integer variable named box. I defined a method named promote which increases box by one:
def promote self[:box] += 1 end
I put a link in the list.rhtml view created by scaffold
... <% for vocab in @vocabs %> ... <td><%= link_to 'Promote', :action => 'promote', :id => vocab %></td> ...
and created a promote message in the controller, which passes it on to the model
def promote @vocab = Vocab.find(params[:id]) @vocab.promote; redirect_to :action => 'list' end
However, this isn't working; the box variable stays the same. Changing the model's method to
def promote value_before = self[:box] self[:box] += 1 value_after = self[:box] logger.error "Oops! First, box was #{value_before} and now it's #{value_after}." end
produces this in development.log:
Oops! First, box was 4 and now it's 5.
So the variable box does change, but the database entry probably hasn't been updated. I also tried write_attribute, but no luck. What am I doing wrong?
Thanks.
