Encoding issue when importing Salesforce data into Rails with the Bulk Api

Question

I am trying to do regular imports of data to rails using rufus-scheduler gem and the salesforcebulk gem.

I've been successful in importing data from one salesforce custom object into my database but when I try to import other objects I run into trouble:

scheduler caught exception:
Encoding::UndefinedConversionError: "\xC3" from ASCII-8BIT to UTF-8: INSERT INTO "channels" ("created_at", "name", "updated_at") VALUES (?, ?, ?)

================================================================================

Here is the code of the object which is successfully retrieved and imported:

scheduler.at("2013-07-03 11:17:15 -0700 ") do

  client = SalesforceBulk::Client.new(username: 'XXXXXXXXX', password: 'XXXXXXXXX')
  client.authenticate

  job = client.add_job(:query, :Paquete__c)

  batch = client.add_batch(job.id, "SELECT Id, Name, Capacidad__c, Organizacion__c FROM Paquete__c")

  job = client.close_job(job.id)

  sleep 5.0

  batch = client.batch_info(job.id, batch.id)

  results = client.batch_result(job.id, batch.id)

  results.each do |d|
    Paquete.find_or_create_by_serie_and_id_and_version(id: d[:Id],
                                                            serie: d[:Name],
                                                            account_id: d[:Organizacion__c],
                                                            capacidad: d[:Capacidad__c])
  end

  puts "Done... Paquetes"

end

Here is the non-working code:

scheduler.at("2013-07-03 11:40:00 -0700 ") do

client = SalesforceBulk::Client.new(username: 'XXXXXXXXXXXX', password: 'XXXXXXXXXXX')
client.authenticate

job = client.add_job(:query, :Account)

batch = client.add_batch(job.id, "SELECT Id, Name, Type FROM Account")
job = client.close_job(job.id)

sleep 5.0

batch = client.batch_info(job.id, batch.id)

results = client.batch_result(job.id, batch.id)

results.each do |d|
Account.find_or_create_by_id_and_name(id: d[:Id], name: d[:Name],type: d[:Type])                                                                

end

puts "Done... Accounts"

end

I've already tried to change the encoding in the CSV parser inside the batch_result method of the salesforcebulk gem without success.

I find very strange that one piece of code is working and the other does not. Perhaps it is something regarding a particular table.

Answer 1

You should focus on the error:

Encoding::UndefinedConversionError: "\xC3" from ASCII-8BIT to UTF-8:
INSERT INTO "channels" ("created_at", "name", "updated_at") VALUES (?, ?, ?)

/Users/arturodiaz/.rvm/gems/ruby-2.0.0-p195@agripa/gems/
activerecord-3.2.13/lib/active_record/connection_adapters/
sqlite_adapter.rb:208:in `encode'

There seems to be a ~n (as in Jalapeño) in your name column and the sqlite adapter does not like it. Probably your Salesforce bulk gem takes some kind of localization setting.

This has nothing to do with rufus-scheduler.
