Define barcode type dinamically

[aribeiro]

Hi,

I'm using has_barcode here, and I'd like to define the barcode type based on the type the user defined in a form. it is possible to give me an example, I'm trying something like this:

class MyModel < ActiveRecord::Base
  include HasBarcode

  BARCODE_SYMBOLOGY = {
    :CODE25 => Barby::Code25,
    :CODE25INTERLEAVED => Barby::Code25Interleaved,
    :CODE25IATA => Barby::Code25IATA,
    :CODE39 => Barby::Code39,
    :CODE93 => Barby::Code93,
    :CODE128 => Barby::Code128,
    :GS1138 => Barby::GS1128,
    :EAN13 => Barby::EAN13,
    :BOOKLAND => Barby::Bookland,
    :UPCA => Barby::EAN13,
    :EAN8 => Barby::EAN8,
    :UPCEAN => Barby::UPCSupplemental
  }

  has_barcode :barcode,
    :outputter => :png,
    :type => Proc.new {|p| BARCODE_SYMBOLOGY[p.barcode_symbology.to_sym] rescue Barby::Code39 },
    :value => Proc.new { |p| p.barcode_string }
...

I'm getting the error: NoMethodError: undefined method `new' for #Proc:0x007f81dd93f8f8

So the user will save the barcode_string and the barcode_symbology like CODE39, and it should generate the barcode based in this two fields.

Thanks

I think you want to use

proc {|p| BARCODE_SYMBOLOGY[p.barcode_symbology.to_sym] rescue Barby::Code39 }
