Is it possible to generate a model that way? Instead of, Test stat1:string stat2:integer stat3:string, is there a way to store arrays/hashes?
Would I just use 'integer' or etc? What if I wanted an array of different types? *sob*
Hi Tim,
Is it possible to generate a model that way? Instead of, Test stat1:string stat2:integer stat3:string, is there a way to store arrays/hashes?
I'm really not sure what you're asking, but I'll try and I'll explain a little that might help you ask again, better, if you need to.
I assume your question is about script/generate model ....
That's generating a bunch of things for you, including a migration that, when run, is going to create a table in a relational database with fields named and typed the way you specified. The model created is initially just a two line text file that Rails uses to know which table to 'talk to.'
So are you asking about storing arrays/hashes in a single field in a relational database? If so, see the 'serialize' method. You'd type the field as a blob.
Would I just use 'integer' or etc? What if I wanted an array of different types? *sob*
In Ruby, which Rails is just helping you write, arrays can contain elements of different types.
irb(main):001:0> arraytest = Array.new => irb(main):002:0> arraytest[0] = 1 => 1 irb(main):003:0> arraytest[1] = 'bob' => "bob" irb(main):004:0> hash_element = Hash.new => {} irb(main):005:0> hash_element = {:color => 'green'} => {:color=>"green"} irb(main):006:0> arraytest[2] = hash_element => {:color=>"green"} irb(main):007:0> arraytest.inspect => "[1, \"bob\", {:color=>\"green\"}]"
HTH, Bill
