no, you can''t If you need information from the session hash in a model, you must hand it to the models method like: def do_something(session_id) ... end and call that from the controller like @my_model.do_something(session[:site_id]) --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

is working ..Now In ServiceDeskAttachment class i have
upload_column :attachment, :store_dir => proc{|inst, attachment|
"uploads/servicedesk/#{@company_name}/#{inst.id}"} # This is not
working
My controller code for attachment is
@service_desk_attachment1=
ServiceDeskAttachment.new(params[:service_desk_attachment1])
@service_desk_attachment1.company_name=session[:company] #this i
tried like from one of above reply
@service_desk_attachment1.save
The in ServiceDeskAttachment class
def set_company(company)
@company_name=company
puts ''in set_company''+ company_name.to_s #Value I get
here

But @company_name how can I set this to the above upload_column so
that it looks like

Yes you could access the session variable in model. Paste the below
code in application.rb
--------------
around_filter :you_dont_have_bloody_clue
protected
def you_dont_have_bloody_clue
klasses = [ActiveRecord::Base, ActiveRecord::Base.class]
methods = ["session", "cookies", "params",
"request"]
methods.each do |shenanigan|
oops = instance_variable_get(:"@_#{shenanigan}")
klasses.each do |klass|
klass.send(:define_method, shenanigan, proc { oops })
end
end
yield
methods.each do |shenanigan|
klasses.each do |klass|
klass.send :remove_method, shenanigan
end
end
end
--------------
Now continue using the session variable in model. It works for me.
Thanks,
Sadeesh.

Hi
Lots of thanks for your help.It is working now..But what actaully
happened? I have the curiosity to know that..Is it anything against the
MVC architecture? And will it create any future problems during
deployment like that?
Thanks

Hi, Probably no problem comes.I am not sure. Its your responsibilty. And you could access all these variables there ["session", "cookies", "params", "request"] . Thanks, Sadeesh.

It was some kind of joke, I believe. The model has no concept of a "session". It shouldn''t be able to tell whether it''s being accessed from a controller or the console or a standalone script. It''s only the controller that knows about sessions. As another respondent said, if you need the model to have session data, you should write your model method to take an argument and then pass the relevant session data in. The model doesn''t know where the method argument comes from, and it shouldn''t know. David -- Rails training from David A.

Hi
The code is not a joke .It is working anyway..And I tried as you
said.(5 th post above)..In the model ServiceDeskAttachment i made a
attr_accessor :company
And from controller I wrote
@sd_attachment=ServiceDeskAttachment.new(params[:attachment_data])
@sd_attachment.company=session[:company]
@sd_attachment.save
And in ServiceDeskAttacment model I I have the following code at top
upload_column :attachment, :store_dir => proc{|inst, attachment|
"uploads/servicedesk/#{@company}/#{inst.id}"}
But this does not get @company value...If I get value there, then my
problem is solved..Could you please tell me how can this be solved?
Thanks in advance

If your model needs external data, then pass it in. When classes have direct access to things that do not belong to them then you''re building a house of cards. If you have a model that needs some external data, then pass it in as an argument. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Hi, I have a scenario where the session variable is handy in the model - I need to be able to get the current value, as it may be changed at any time. I have a delayed_job that runs a long running model activity (calling multiple web services, populating the database, etc.) in the background. This is triggered when a user selects an item from a list in the UI. However, if the user clicks on another item, I want the current processing to stop, as I want to keep the delayed_job worker pool as free as possible (the more the jobs, the more I am billed by the hoster). The only way I can see to achieve this is to set a session variable (session[:current_topic_id]) when the user clicks on a topic, and then check in each stage of the model action if the current topic is the same as the one stored in the session, and abort the long job if they are out of sync. Here, passing in the session variable to the model method wont really work for me, I have to pass in the session id and check the variable value across the model code.

I tried passing the session id around to the model, and agree that it is very ugly. I am curious to know how you can best achieve this scenario without passing in the session variable: abort a delayed_job (or other model based) work item when user changes something - this is mainly required because delayed job workers cost money at my host (heroku) and if the user randomly clicks around on the UI, I dont want to be billed for all the spawned jobs that no one cares about anyway.
