Implementation of downloading process in de.oddb.org

Just for information in the furture development related to invoice system

Data preparation

  • Run de.oddb.org/bin/oddbd
  • Run de.oddb.org/bin/exportd 
masa@masa ~/ywesee/de.oddb.org $ jobs/export_csv
masa@masa ~/ywesee/de.oddb.org $ ls var/downloads -al
insgesamt 5552
drwxr-xr-x 2 masa masa      56 17. Nov 08:50 .

Test @session data

1. lib/oddb/html/util/validator.rb 

  EVENTS = [ :ajax_autofill, :ajax_create_active_agent,
...
             #:sequence, :sort, :update ]
             :sequence, :sort, :update, :grant_download ]

2. lib/oddb/html/state/global.rb 

module ODDB
  module Html
    module State
class Global < SBSM::State
...
  def grant_download
    p ODDB.config.export_dir
    p @session.user_input(:file)
  end

Result 

"/home/masa/ywesee/de.oddb.org/var/downloads"
"de.oddb.csv"

Note

  • Good

Test a case in which there is no target file

lib/oddb/html/state/global.rb 

module ODDB
  module Html
    module State
class Global < SBSM::State
...
  def grant_download
    Download.new(@session, '/home/masa/work/test.dat')
  end

Result

  • 'Es tut uns leid' on browser

Test downloading

lib/oddb/html/state/global.rb 

  def grant_download
    _download(@session.user_input(:file))
  end

Result

  • Succeeded in downloading var/downloads/de.oddb.csv

Next

  • Check user 'exprired?'
  • Define a class somewhere for a download user

Define a GrantDownload class

Notes

  • Where should I define the class for the expiry check?, and class name.
  • I want to use 'save' and 'find_by_uid' methods, it should inherit Model class

Test defining a class

lib/oddb/business/grant_download.rb 

#!/usr/bin/env ruby
# ODDB::Business::GrantDownload -- de.oddb.org -- 17.11.2011 -- mhatakeyama@ywesee.com

require 'oddb/model'

module ODDB
  module Business
    class GrantDownload < Model
    end
  end
end

lib/oddb/html/state/global.rb 

  def grant_download
    if(user = ODDB::Business::GrantDownload.find_by_uid(1))
      p "AAA"
    else
      p "BBB"
    end
    #_download(@session.user_input(:file))
  end

Result 

"BBB"

Note

  • The class is recognized

Test bin/admin grant_download command

lib/oddb/util/server.rb 

      def grant_download
        "WWW"
      end

Run bin/adim 

masa@masa ~/ywesee/de.oddb.org $ bin/admin
de.oddb> grant_download
-> WWW
de.oddb>

Note

  • The method is recognized

Implement GrantDownload class and grant_download method

lib/oddb/business/grant_download.rb 

#!/usr/bin/env ruby
# ODDB::Business::GrantDownload -- de.oddb.org -- 17.11.2011 -- mhatakeyama@ywesee.com

require 'oddb/model'

module ODDB
  module Business
    class GrantDownload < Model
    end
  end
end

lib/oddb/util/server.rb 

      def grant_download
        "WWW"
      end

Question

  • How can I search the cache by the other data than odba_id?

Experiment

lib/oddb/business/grant_download.rb 

#!/usr/bin/env ruby
# ODDB::Business::GrantDownload -- de.oddb.org -- 17.11.2011 -- mhatakeyama@ywesee.com

  module Business
    class GrantDownload < Model
      #multilingual :email
      #attr_reader :grant_list, :download_history
      attr_reader :email, :grant_list, :download_history
      def initialize(email)
        @email = email
        @grant_list = {}
        @download_history = []
      end
    end
  end
end

lib/oddb/persistence/odba/business/grant_download.rb 

#!/usr/bin/env ruby
# ODDB::Business::GrantDownload -- de.oddb.org -- 17.11.2011 -- mhatakeyama@ywesee.com

require 'oddb/persistence/odba/model'

module ODDB
  module Business
    class GrantDownload < Model
      odba_index :email, 'email.all'
    end
  end
end

lib/oddb/persistence/odba.rb 

require 'oddb/persistence/odba/business/grant_download'

lib/oddb/util/server.rb 

      def grant_download(arg1, arg2='')
        if arg1 == 1
          user = ODDB::Business::GrantDownload.new(arg2)
          user.save
          p user
          user.uid
        elsif arg1 == 2
          user = ODDB::Business::GrantDownload.find_by_uid(arg2)
          p user
          user
        elsif arg1 == 3
          user = ODDB::Business::GrantDownload.find_by_email(arg2)
          p user
          user
        elsif arg1 == 4
          user = ODDB::Business::GrantDownload.find_by_uid(arg2)
          p user
          user.delete
        end
      end

Notes

  • find_by_email method is recognized but find_by_email method failed, does not find any object
  • Why?

Notes

  • find_by_email method Works!!
  • find_by_* method finds the last entry record if there is the same index
  • key points are 'multilingual' attribute in lib/oddb/business/grant_download.rb
  • if only attr_* attribute is set for :email, find_by_email does not work. I do not know why.
  • in de.oddb.org, the class definition under lib/oddb/persistence/odba/ should be necessary
