为什么我会得到“未定义的方法`编码’”？
我怎样才能解决这个问题？

解决方法
我发现你正在为bcc获得正确的数组,可能你有一些错误的电子邮件地址.
当一个电子邮件地址在@之前包含一个点时,例如test.@ test.com,并作为一个数组的一部分提交,你得到一个未定义的方法`encoding’for Array.该错误仅出现在Ruby 1.9中,并且仅在地址作为数组提交时才出现.
试试这个
def call_email(users_emails,mesesage_body)
@users_emails = users_emails
@mesesage_subject = mesesage_subject
@mesesage_body = mesesage_body
mail(
:bcc => @users_emails.join(','),:body => @mesesage_body) do |format|
format.html
end
end
