Question

我尝试使用simple_form收集一个或多个电子邮件地址，然后将这些电子邮件地址作为数组传递，以便ActionMailer可以向这些地址发送邀请电子邮件。不确定如何将所有输入字段放入一个传递给控制器和邮件程序的数组中。这是我到目前为止所拥有的。

输入表格：

<div class="user-group-partial">
<%= simple_form_for :user_emails, :url => "/user_groups/sent_emails/", :method => :post do |f| %>
    <%= f.error_notification %>
    <div class="form-inputs">
            <%= f.input :email, :maxlength => 25 %>
            <%= f.input :email, :maxlength => 25 %>
            <%= f.input :email, :maxlength => 25 %>
        <br>
        <div class="form-actions">
            <%= f.button :submit, :class => "btn btn-primary", :value => "Invite Bros" %>
        </div>
    </div>
<% end %>
<br>

控制器方法：

def send_invite_to_members   
    token = current_user.user_group.token
    email = params[:user_emails][:email]
    UserGroupMailer.group_invitation_email(email, token).deliver
    redirect_to '/user_groups', :notice => "Your invitations have been sent"
end

ActionMailer方法：

def group_invitation_email(email_address, token)
    @token = token.to_s
    mail to: email_address, subject: "You've been invited!"
end

谢谢！

解决此问题的一种简单方法是使用带有帮助程序标签的文本字段，该文本字段指示用户键入以空格或逗号分隔的电子邮件地址。

然后在您的控制器中，您可以拆分它们并发送每封电子邮件，例如：

def send_invite_to_members   
  token = current_user.user_group.token
  emails = params[:user_emails][:emails].split(",") # or split(" ") if you want them separated by a space
  emails.each do |e|
    UserGroupMailer.group_invitation_email(e, token).deliver
  end
  redirect_to '/user_groups', :notice => "Your invitations have been sent"
end

将simple_form中的输入添加到数组中
