Fails to update multi-select fields.

[mbreen]

I have a multi-select field that has options: Yes, No, Confirmed.

The field is set to ["Yes"], and I want to be set to ["Yes", "Confirmed"]

I found that I can't just add one - I have to clear it first. So instead of:

contact["Next delivery"].push("Confirmed")
contact.save

I have to do:

result = contact["Next delivery"].push("Confirmed")
contact["Next delivery"] = []
contact["Next delivery"] = result
contact.save

I looked at this briefly and it stems from the way that changes are tracked based on using the = setter method. Making changes directly to an array field doesn't use this method so the @updated_keys value is never changed. I don't see a quick/easy way to solve this.

airrecord/lib/airrecord/table.rb

Lines 125 to 130 in f2bf601

	def []=(key, value)
	validate_key(key)
	return if fields[key] == value # no-op
	@updated_keys << key
	fields[key] = value
	end

@mbreen you could simplify your code a bit. You don't need to clear out the existing value, you just need to overwrite it with a new array:

contact["Next delivery"] += ["Confirmed"]
=> ["Yes", "Confirmed"]
contact.save
