Question

我正在开发一个允许用户向另一个人发送电子邮件的电子邮件系统。我希望用户能够做的是能够指定他们发送电子邮件的电子邮件地址 - 所以，当电子邮件从我已编码为development.rb的通用电子邮件地址发送时，按照下面：

Rails.application.configure do

  config.cache_classes = false

  config.eager_load = false

  config.consider_all_requests_local       = true
  config.action_controller.perform_caching = false

  config.action_mailer.raise_delivery_errors = false

  config.active_support.deprecation = :log

  config.active_record.migration_error = :page_load
  config.assets.debug = true

  config.assets.digest = true

  config.assets.raise_runtime_errors = true

  config.action_mailer.delivery_method = :smtp
  config.action_mailer.smtp_settings = {
    address:              'smtp.gmail.com',
    port:                 587,
    domain:               'example.com',
    user_name:            'myemail@emailaddress.com', #replace with your username Eg. john.smith
    password:             'mypassword', #replace with your gmail password
    authentication:       'plain',
    enable_starttls_auto: true  }

end

因此，根据用户在表单上输入的内容，我希望更改development.rb，以便可以从用户的帐户发送电子邮件。我假设某种实例变量是必要的，但这可能吗？

我的表格如下：

<%= form_for @email do |f| %>

  <% if @email.errors.any? %>
    <div id="error_explanation">
      <h2>
        <%= pluralize(@email.errors.count, "error") %> prohibited
        this email from being saved:
      </h2>
      <ul>
        <% @email.errors.full_messages.each do |msg| %>
          <li><%= msg %></li>
        <% end %>
      </ul>
    </div>
  <% end %>

  <p>
    <%= f.label :address %><br>
    <%= f.text_field :address %>
  </p>
  <p>
    <%= f.label :port %><br>
    <%= f.text_field :port %>
  </p>
  <p>
    <%= f.label :domain %><br>
    <%= f.text_field :domain %>
  </p>

  <p>
    <%= f.label :user_name %><br>
    <%= f.text_field :user_name %>
  </p>

  <p>
    <%= f.label :password %><br>
    <%= f.text_field :password %>
  </p>
  <p>
    <%= f.label :authentication %><br>
    <%= f.text_field :authentication %>
  </p>
  <p>
    <%= f.label :bcc_address %><br>
    <%= f.text_field :bcc_address %>
  </p>

  <p>
    <%= f.label :enable_starttls_auto %><br>
    <%= f.text_field :enable_starttls_auto %>
  </p>
  <p>
    <%= f.label :cc_address %><br>
    <%= f.text_field :cc_address %>
  </p>
  <p>
    <%= f.label :bcc_address %><br>
    <%= f.text_field :bcc_address %>
  </p>

  <p>
    <%= f.label :title %><br>
    <%= f.text_field :title %>
  </p>

  <p>
    <%= f.label :text %><br>
    <%= f.text_area :text %>
  </p>

  <p>
    <%= f.submit %>
  </p>

<% end %>

我的控制器有以下内容：

def create
    @email = Email.new(email_params)
    if @email.save
        UserMailer.welcome_email(@email).deliver
        redirect_to @email
    else
        render 'new'
    end
end
private
    def email_params
        params.require(:email).permit(:address, :port, :domain, :user_name, :password, :authentication, :enable_starttls_auto, :to_address, :cc_address, :bcc_address, :title, :text)
    end

我的邮件是：

class UserMailer < ApplicationMailer
  default from: 'no-reply@example.com'

  def welcome_email(email)
    @url  = 'http://localhost:3000/users/login'
    @email = email
    mail(to: @email.to_address, cc: @email.cc_address, bcc: @email.bcc_address, subject: @email.title)
  end
end

但是用户是否可以输入他们的电子邮件详细信息，然后系统会在development.rb文件中使用这些信息发送电子邮件？

Answer 1

根据您的要求，您无需更改邮件设置。请按以下步骤操作：

class UserMailer < ApplicationMailer


def welcome_email(email)
 @url  = 'http://localhost:3000/users/login'
 @email = email
 mail(from:"example@example.com",to: @email.to_address, cc: @email.cc_address, bcc: @email.bcc_address, subject: @email.title)
end
end

代替from，您需要将用户的电子邮件发送到您想要发送邮件的帐户。
