Where to put require 'gem' statements?

Rails
1

Hello,

I’ve seen all sorts of places where people put their ‘require’
statements,
and I’m not sure what the best solution is. I’m currently using it
directly
in a model/csv_processor.rb:

require ‘fastercsv’

class CsvProcessor
def self.create_csv_table(file)
…
FCSV.parse(…
…
end

I’m calling this from controllers/loader_controller.db:

my_csv_table = CsvProcessor.create_csv_table(params[:file_ref])

Works perfectly. But generally, where is the place to put all those
require statements? Is it in config/environment.rb? Would it be correct
to add them just at the end of this file?

I already tried this with another “processor”, which needs the
ruby-plsql
gem. So I added at the end of environment.rb the statements:

require ‘ruby-plsql’
plsql.activerecord_class = ActiveRecord::Base
plsql.connection.autocommit = false

But this didn’t work. I couldn’t start webrick anymore. Having instead
the same statements at the beginning of model/plsql_processor.rb
works without problems.

Any help would be appreciated,

Martin

Well if it’s a gem then using config.gem inside config/environment.rb
is usually the way to go. You don’t want to just stick things at the
bottom of environment.rb - in production mode your app’s code gets
loaded before the bottom of environment.rb gets executed. If you put
stuff in an initializer (ie in a file in config/initializers) then it
will get run early enough.
