Ruby CSV read strings and numbers from MySQL exported csv - sql

Question

I exported tables and queries from SQL.
The ruby (1.9+) way to read csv appears to be:
require 'csv'
CSV.foreach("exported_mysql_table.csv", {:headers=>true}) do |row|
puts row
end
Which works great if your data is like this:
"name","email","potato"
"Bob","bob#bob.bob","omnomnom"
"Charlie","char#char.com","andcheese"
"Doug","diggyd#diglet.com","usemeltattack"
Works fine (The first line is a header, the attributes). However, if the data is like this:
"id","name","email","potato"
1,"Bob","bob#bob.bob","omnomnom"
2,"Charlie","char#char.com","andcheese"
4,"Doug","diggyd#diglet.com","usemeltattack"
Then we get the error:
.rbenv/versions/1.9.3-p194/lib/ruby/1.9.1/csv.rb:1894:in `block (2 levels) in shift': Missing or stray quote in line 2 (CSV::MalformedCSVError)
I think this is because the id is stored as a number, not a string, and thus has no quotes, and the csv parser expects ALL the entries to have quotes. Ideally I'd like to read "Bob" as a string and 1 as a number (and stuff it into a Hash of hashes)
(Have tried 'FasterCSV', that gem became 'csv' since ruby 1.9)
EDIT:
Was pointed out that the example worked fine (derp), was looking in the wrong place, it was an error with multi-line fields, question moved to Ruby CSV read multiline fields

Answer 1

Using the input you provided, I am unable to reproduce this.
1.9.3p194 :001 > require 'csv'
=> true
1.9.3p194 :002 > CSV.foreach("test.txt", {:headers => true}) { |row| puts row }
1,Bob,bob#bob.bob,omnomnom
2,Charlie,char#char.com,andcheese
4,Doug,diggyd#diglet.com,usemeltattack
=> nil
The only difference I see between our environments is that you are using rbenv, and I am using RVM. I also verified this on another machine I have with ruby 1.9.3-p194. Does the input you provided exactly match what is in your csv?
