允许客户将图像附加到联系表单

Question

我有以下联系表格，我想允许客户将图像作为附件发送给我。我已将字段添加到表单中，但不了解以下内容 -

• 我创建了哪些迁移？
• 如何将图像附加到 邮寄者？

视图

<%= simple_form_for @inquiry, :method => :post do |f| %>
  <%= f.input :spam, as: :hidden %>
  <%= f.input :name %>
  <%= f.input :phone %>
  <%= f.input :email %>
  <%= f.input :message %>
  <%= f.file_field :image %> ## Attachment input here
  <%= f.button :submit, 'Send' %>
<% end %>

控制器

  def new
    @inquiry = Inquiry.new
  end

  def create
    redirect_to new_inquiry_path and return if params[:spam].present?
    @inquiry = Inquiry.new(inquiry_params)
    if @inquiry.valid?
      InquiryMailer.admin(@inquiry).deliver
      redirect_to inquiries_path
    else
      render :new
    end
  end

  private

  def inquiry_params
    params.require(:inquiry).permit(:name, :email, :phone, :message)
  end

模型

  validates :name, presence: true
  validates :email, presence: true
  validates :phone, presence: true
  validates :message, presence: true

inquiry_mailer.rb

class InquiryMailer < ActionMailer::Base
  default from: "noreply@foo.com"

  def admin(inquiry)
    @inquiry = inquiry
    mail to: "hello@foo.co.uk", subject: "Website Inquiry"
  end
end

admin.text.erb

Website Inquiry
=========

Name: <%= @inquiry.name %>
Phone: <%= @inquiry.name %>
E-Mail: <%= @inquiry.email %>
Message: <%= @inquiry.message %>

您可以在此处使用ActionMailer

我会根据您现有的设置提供答案

您需要编辑邮件以查找此类内容

class InquiryMailer < ActionMailer::Base
default from: ENV['EMAIL_ADDRESS'] #I like to keep my email address hidden

  def admin(inquiry)
    @inquiry= inquiry
     if inquiry.file
       attachment_name = inquiry.file.original_filename
       attachments[attachment_name] = inquiry.file.read
     end
     mail(to: ENV['EMAIL_ADDRESS'], subject: 'Website Inquiry')
  end
end

您可以保持admin.text.erb不变，并且您的控制器保持不变

并在您的form_for中忘记添加

<%= simple_form_for @inquiry, :method => :post, :multipart => true do |f| %>

因此您可以添加附件

认为这是我的头脑
