Rails - Storing a ActionMail Mail.new object in the database

问题

I'm creating a mail object like so:

 textpart_to_inject= params[:text]
 htmlpart_to_inject= params[:html]

  message_all = Mail.new do
    to #{params[:to]}
    from #{params[:from]}
    subject #{params[:subject]}
    text_part do
      body textpart_to_inject
    end
    html_part do
      content_type 'text/html; charset=UTF-8'
      body  htmlpart_to_inject
    end
  end

I then want to insert that into the database like so:

@incoming_mail = IncomingMail.create(:message_all => Base64.encode64(message_all), :message_plain => Base64.encode64(params[:text]))

But that errors with:

TypeError (can't convert Mail::Message into String):
  app/controllers/incoming_mails_controller.rb:56:in `create'

My database columns are as follows: message_all = bytea message_plain = text

Ideas? thanks

回答1:

Have you looked at Rails's serialize method? It sounds like that's exactly what you want to do. See the docs here (also check out the section about 1/6 from the top under the heading "Saving arrays, hashes, and other non-mappable objects in text columns"). It might even be as simple as adding

serialize :message_all
serialize :message_plain

to your IncomingMail model, but don't take my word on that.

Your error, by the way, is coming up because Base64.encode64() only works on strings.

Hope this helps!
