Well folks let me try to explain my problem.
I have a database of musics and each music can have multiple
artists through other table/model in the case Performers.
I would like to record music in new/edit add
artists and select them via a combo-box, used a
simple collection_select, and used to add a new one a UJS
i see on Railscasts.
In the testing phase with few records everything was fine, but I have
a legacy database table where the artists have 62k records.
Well … sure takes 18s to execute the query and render the
page. and if I try to add a new artist with javascript
app dies.
I tried to use fragment caching to the select this did not work.
I also tried using memcached, it is limited to 1M, and my
query takes 5M, removed this limit and yet the system continues
crashing when I add the javascript.
my knowledge (almost none) to prevent me from creating javascript
Another method of adding artists.
I do not know if there is a way to improve performance through caching
or
whether it is design problem.
The environment is: Ruby 1.9.3, Rails 2.3.3, MySQL 5.5
if someone could understand my problem and it is with great humor can
look at this code snippet
Since already thank you very much.
