Hi,
I want to initialize some variables once on startup with static data
from the db. The code is at the bottom. Here are all the scenarios I
tested:
1) Call Setup.state_list inside environment.rb before the
[i]Rails::Initializer.run do |config| [/i]line. Then call the
Setup.state_list from a controller.
2) Call Setup.state_list inside environment.rb at the end of the file.
Then call the Setup.state_list from a controller.
3) Only call the Setup.state_list from a controller.
4) Only call the Setup.state_list from a view helper - never in the
controller.
Please not that I''ve tried this with Setup being a class or module.
The
results from the scenarios are:
1 & 2) Every time I call the Setup.state_list from the controller it
will rebuild the list.
3) It will only initialize the variable the first time through.
4) Every time I call the Setup.state_list from the view helper it will
rebuild the list.
Great - so it appears that scenario 3 works. The problem is that this
isn''t done at startup. I don''t want the system to start if it
can''t
initialize this and other information. Is something going on when I
call it from the environment.rb file that I''m not aware of? I know the
code could be written better, however, it does work. Does anyone have
any thoughts on how to do this?
Thanks in advance!
