Answer 1

use attachment attribute
attachments['file-name.pdf'] = File.read('file-name.pdf').
def welcome(user)
attachments['file-name.pdf'] = File.read('path/to/file-name.pdf')
mail(:to => user, :subject => "Welcome!")
end
refer this (2.3) :
http://guides.rubyonrails.org/action_mailer_basics.html
Modify your code to this:
def send_help_enterprise
p '-----------------'
p params
Mailer.help_enterprise_issue(params[:app], params[:version], params[:name], params[:description][:text], params[:file])
respond_to do |format|
format.js {
render :layout => false
}
end
end
in your mailer
def help_enterprise_issue(app,version,name,description,file)
#app = app
#version = version
#name = name
#description = description
#email = 'test#gmail.com'
attachments['attachment.extension'] = file
mail :to => #email,
:subject => I18n.t('mailer.info.help_enterprise_issue')
end
Thisshould work

Answer 2

Based on http://guides.rubyonrails.org/action_mailer_basics.html, you have to add attachments['file-name.jpg'] = File.read('file-name.jpg'). So, you can put in this method.
def help_enterprise_issue(app,version,name,description)
attachments['file-name.jpg'] = File.read('file-name.jpg')
#app = app
#version = version
#name = name
#description = description
#email = 'test#gmail.com'
mail :to => #email,
:subject => I18n.t('mailer.info.help_enterprise_issue')
end
I hope it can help you.
