You can make use of ActionMailer here
Ill provide an answer based upon your existing setup
You need to edit your mailer to look something like this
class InquiryMailer < ActionMailer::Base
default from: ENV['EMAIL_ADDRESS'] #I like to keep my email address hidden
def admin(inquiry)
#inquiry= inquiry
if inquiry.file
attachment_name = inquiry.file.original_filename
attachments[attachment_name] = inquiry.file.read
end
mail(to: ENV['EMAIL_ADDRESS'], subject: 'Website Inquiry')
end
end
You can keep admin.text.erb as it is and your controller stays the same
and within your form_for dont forget to add
<%= simple_form_for #inquiry, :method => :post, :multipart => true do |f| %>
so you the attachment can be added
Think thats it off the top of my head
