如何解决Rails 3，Action Mailer，电子邮件内容的附件和验证
| 我已经制作了一个简单的表格，用于发送带有附件的电子邮件。问题是我不知道如何使它在邮件程序中工作。到目前为止，我发现的所有教程都涵盖了以下场景：附件的文件已经在服务器的某个位置，而我无法找到有关验证电子邮件内容的任何信息。 因此，我有两个问题要问您： 如何让用户发送带有他们上传的附件的电子邮件？ 如何验证用户的输入和附件扩展名？ 我的电子邮件表格...<div id=\"form_wrapper\">
<%= form_for(:kontakt,:url => {:action => \'kontakt\'},:html => { :multipart => true },:remote=>true) do |f| %>
<ul>
<li>
<%= f.label(:email) %>
<%= f.text_field(:email) %>
</li>
<li>
<%= f.label(:content) %>
<%= f.text_area(:content,:size => \"42x7\") %>
</li>
<li>
<%= f.label(:preview,:class=>:preview )%>
<%= f.file_field :preview %>
</li>
</ul>
<%= image_submit_tag(\"blank.gif\",:id=>\"send_email\",:class=>\"action submit\") %>
<%= link_to(\"Reset\",{:controller=>\'frontend\',:action => \'index\'},:remote => true,:class => \'action reset\') %>
<% end %>
</div>
<%= javascript_include_tag \'jquery.form.js\',\'jquery.rails\',\'jquery.remotipart\' %>
class Contact < ActionMailer::Base
default :from => \"xxxxx@gmail.com\"
def wiadomosc(email)
@content=email[:content]
file=email[:preview]
attachments[file.original_filename] =File.read(file.path)
mail(
:subject=>\"www.XXXXXX.pl - you\'ve got a new message\",:reply_to =>\"xxxxx@gmail.com\",:to => email[:email]
)
end
end
attachments[file.original_filename] =File.read(file.path)
解决方法
我发现，如果您要发送带有附件的电子邮件，请以这种方式附加...
attachments[file.original_filename] = File.open(file.path,\'rb\'){|f| f.read}
def message(email)
@content=email[:content]
unless email[:email_attachment].nil?
file=email[:email_attachment]
attachments[file.original_filename] = File.open(file.path,\'rb\'){|f| f.read}
end
mail(
:subject=>\"www.XXXXXX.pl - you\'ve got a new message\",:reply_to =>\"xxxxx@gmail.com\",:to => email[:email]
)
end
def self.columns() @columns ||= []; end
def self.column(name,sql_type = nil,default = nil,null = true)
columns << ActiveRecord::ConnectionAdapters::Column.new(name.to_s,default,sql_type.to_s,null)
end
column :name,:string
column :company,:string
column :email,:string
column :content,:text
column :type_of_question,:string
column :email_attachment,:string
has_attached_file :email_attachment
EMAIL_REGEX = /\\A[\\w+\\-.]+@[a-z\\d\\-.]+\\.[a-z]+\\z/i
TYPES = [\'application/zip\',\'multipart/x-zip\',\'application/x-zip-compressed\']
validates :name,:presence => {:message => \"Blah blah blah\"}
validates :email,:presence => {:message => \"Blah blah blah\"},:format=>{:unless=> Proc.new{|s| s.email.nil?|| s.email.empty? },:with => EMAIL_REGEX,:message => \"Blah blah blah\"}
validates :content,:presence => {:message => \"Blah blah blah\"}
validates_inclusion_of :type_of_question,:in => [\"Blah1\",\"Blah2\",\"Blah3\"],:message => \"%{value} is not on the list of types\"
validates_attachment_content_type :email_attachment,:content_type => TYPES,:message => \"The attachment has wrong extension...\"
