Hi,

How to I get a rails line of code that normally works within a rails  
mode, but but have it run within “test.rb” environment file. For  
example to get the following to run:

RecurringType.create(:name =\> “TYPE\_BASIC”)

PS. Or in general how to get a normal rails line of code to run in the  
“test.rb” file (i.e. only for when starting up in test mode). I get  
“ActiveRecord::ConnectionNotEstablished” when I include  
“RecurringType.create(:name =\> “TYPE\_BASIC”)”.

thanks

You need to make your code run after the framework has been fully  
initialized (which it isn’t when test.rb runs). Application  
initializers (files in config/initializers) run after this as do  
config.after\_initialize blocks.

thanks Fred - I hadn’t come across these before…

So can I create a “test.rb” file in the “initializers” directory such  
that it would only run it for the “test” environment? Or if not what  
would you recommend re approach to ensure the code was only run when  
in a specific environment (e.g. ‘test’ in this case)?

Thanks

stuff in config/initializers is always run, but you can of course  
stick a if RAILS\_ENV == ‘foo’ in there. I tend to keep the stuff in  
their group by purpose.  
The config.after\_initialize thing wouldn’t require you to test what  
the environment is.

Fred - re “The config.after\_initialize thing wouldn’t require you to  
test what the environment is” - what do you mean by this? where would  
the code go in this case such that there would be a way to have it  
only run for the ‘test’ environment?
