[Rails] Re: Reading value from .yml file in controller

[Rails] Re: Reading value from .yml file in controller
You could create a constant in your ServiceDesk or OpenServiceDesk
model (not sure how you've set your models up)...
class ServiceDesk < ActiveRecord::Base
DEFAULTS = {:service_desk_status_id => 1, :service_desk_category_id
=> 1, :service_desk_sub_category_id => 1}
end
Then in your controller you could use
yourobject.service_desk_status_id = DEFAULTS[:service_desk_status_id]
Perhaps there's a good argument against using a constant like this, I
don't know, but to me it looks like a pretty simple way to do it.
Or, as Fred suggested, create a migration to make the DB handle the
default values, like so:
change_column :tablename, :service_desk_status_id, :integer, :default
=> 1

Hi Thanks for the reply.May I ask one more question? As Daniel Bush said this isn't a test fixture but just a file that is being used to set default values..So my question normally in which directory I can store this yml file whether inside models or view or anywhere?

I was going to take a different tack. Assuming this isn't a test
fixture
but just a file that is being used from somewhere to set default
values
for new objects, then you could do:
default_values=YAML.load_file('path/to/get_value.yml')
There are probably other ways to set defaults rather than loading up a
file like this though.
You could embed them in a class method in the model and just pull them
out when you
need them. Or maybe apply them in a callback (http://
api.rubyonrails.org/classes/ActiveRecord/Callbacks.html) like
before_create. Or use :default in your migration when defining the
table - might not be appropriate doing this with id's though.
Callback example:
class Foo < ActiveRecord::Base
before_create :apply_defaults
private
def apply_defaults
self.field1='val1' if self.field1.blank?
end
end

[Rails] Re: Reading value from .yml file in controller
Assuming that your yaml file is in test/fixtures directory. Do
something like this
#say ticket is an object going to be created
yml=File.open("#{RAILS_ROOT}/test/fixture/get_value.yml){|ym|
YAML::load(ym) }
ticket.service_desk_status_id=yml["sd"]
["service_desk_status_id"].to_i #assuming it to be integer
ticket.service_desk_category_id=yml["sd"]
["service_desk_category_id"].to_i
ticket.service_desk_sub_category_id=yml["sd"]
["service_desk_sub_category_id"].to_i
