我有這些時刻之一。我的問題可能很簡單，但我沒有弄清楚。Rails 5表格中的聯繫人表單數據
我有一個我正在開發的Rails 5應用程序。它包含聯繫人填寫和提交的聯繫表單。
接下來，我將ActionMailer設置爲向聯繫人發送電子郵件，通知他們他們的郵件已收到並正在接受審閱。我也有ActionMailer設置發送電子郵件到網站管理員，應該包含聯繫人表單數據。這是我遇到問題的地方。如何將聯繫表單數據傳遞到我的電子郵件視圖？
這裏是contacts_controller：
class ContactsController < ApplicationController
before_action :set_contact, only: [:show, :edit, :update, :destroy]
# GET /contacts
# GET /contacts.
def index
@contacts = Contact.all
end
# GET /contacts/1
# GET /contacts/1.json
def show
end
# GET /contacts/new
def new
@contact = Contact.new
end
# GET /contacts/1/edit
def edit
end
# POST /contacts
# POST /contacts.json
def create
@contact = Contact.new(contact_params)
respond_to do |format|
if @contact.save
FormMailer.message_received(@contact).deliver_now
FormMailer.new_web_message(@email).deliver_now
format.html { redirect_to thank_you_path, notice: 'Your message was sent.' }
format.json { render :show, status: :created, location: @contact }
else
format.html { render :new }
format.json { render json: @contact.errors, status: :unprocessable_entity }
end
end
end
# PATCH/PUT /contacts/1
# PATCH/PUT /contacts/1.json
def update
respond_to do |format|
if @contact.update(contact_params)
format.html { redirect_to @contact, notice: 'Contact was successfully updated.' }
format.json { render :show, status: :ok, location: @contact }
else
format.html { render :edit }
format.json { render json: @contact.errors, status: :unprocessable_entity }
end
end
end
# DELETE /contacts/1
# DELETE /contacts/1.json
def destroy
@contact.destroy
respond_to do |format|
format.html { redirect_to contacts_url, notice: 'Contact was successfully destroyed.' }
format.json { head :no_content }
end
end
private
# Use callbacks to share common setup or constraints between actions.
def set_contact
@contact = Contact.find(params[:id])
end
# Never trust parameters from the scary internet, only allow the white list through.
def contact_params
params.require(:contact).permit(:first_name, :last_name, :vehicle_type, :tire_size, :current_tire, :phone_number, :email, :message)
end
end
的梅勒：
class FormMailer < ApplicationMailer
# Subject can be set in your I18n file at config/locales/en.yml
# with the following lookup:
#
# en.form_mailer.message_received.subject
#
def message_received(contact)
@contact = contact
@url = 'http://example.com'
@greeting = "Hello"
mail(to: @contact.email, subject: 'Thanks for contacting Halstead Tire LLC')
end
def new_web_message
@greeting = "Hello"
@email = '<[email protected]>'
@website = 'http://www.example.com'
mail(to: @email, subject: 'A new message from your website.')
end
end
視圖new_web_message.html.erb：
<h1><%= @greeting %> Nathan,</h1>
<p>
Someone's requested some information from your site. Please go to <%= @website %> to get the details.
</p>
<body>
</body>
我有電子郵件發送正確的，他們是按預期交付。聯繫人的消息正在完美工作。我想讓Admin *（new_web_message）*電子郵件接收聯繫人的信息併發送。我如何將這些值傳遞給視圖？我想將所有contact_params *（來自contacts_controller）*並將它們放入電子郵件中的管理員。我意識到這可能是一個簡單而愚蠢的錯誤，但我無法弄清楚。是否有可能在一個郵件程序中完成這一切，或者我是否需要爲聯繫人和管理員*（new_web_message）*提供單獨的郵件程序？ *正如我所說的，現在郵件工作正常，但是我只需要將表單中的數據傳遞給管理員**（new_web_message）*電子郵件。
在電子郵件聯繫它的工作訪問，像這樣的數據是在郵件很明顯：
@contact.email
@contact.phone_number
@contact.message
等等。爲什麼在管理員電子郵件中這種理論不起作用？
我的郵件程序是否需要與控制器（contacts_mailer）相同，而不是（FormMailer），因爲我現在命名它？
謝謝！
編輯：
所以我實現了瑞恩的代碼在我的應用程序，但現在我得到：
NoMethodError in Contacts#create
這裏是new_web_message.html.erb
<h1><%= @greeting %> Nathan,</h1>
<p>
Someone's requested some information from your site. Please go to <%= @website %> to get the details.
</p>
<body>
<p><%= @contact.first_name %></p>
<p><%= @contact.last_name %></p>
</body>
這裏顯示的錯誤當我提交表格時：
Showing /Users/evan/htire/app/views/form_mailer/new_web_message.html.erb where line #7 raised:
undefined method `first_name' for nil:NilClass
Extracted source (around line #7):
</p>
<body>
<p><%= @contact.first_name %></p> (line 7)
<p><%= @contact.last_name %></p> (line 8)
</body>
顯然我需要在某處定義方法，但我正在用盡想法。 （是的，我有點新的軌道）
這是模型聯繫。使用瑞安的建議RB
class Contact < ApplicationRecord
def new_web_message
first_name = first_name
last_name = last_name
end
attr_accessor :first_name, :last_name, :vehicle_type, :tire_size, :current_tire, :phone_number, :email, :message
validates_presence_of :first_name
validates_presence_of :last_name
validates_presence_of :phone_number
validates_presence_of :message
end
更新郵件：
class FormMailer < ApplicationMailer
# Subject can be set in your I18n file at config/locales/en.yml
# with the following lookup:
#
# en.form_mailer.message_received.subject
#
def message_received(contact)
@contact = contact
@url = 'http://halsteadtire.net'
@greeting = "Hello"
mail(to: @contact.email, subject: 'Thanks for contacting Halstead Tire LLC')
end
def new_web_message(contact, params)
@contact = contact
@greeting = "Hello"
@email = '<[email protected]>'
@website = 'http://www.halsteadtire.net/contacts'
mail(to: @email, subject: 'A new message from your website.')
end
end
使用瑞安的代碼更新控制器：
class ContactsController < ApplicationController
before_action :set_contact, only: [:show, :edit, :update, :destroy]
# GET /contacts
# GET /contacts.json
def index
@contacts = Contact.all
end
# GET /contacts/1
# GET /contacts/1.json
def show
end
# GET /contacts/new
def new
@contact = Contact.new
end
# GET /contacts/1/edit
def edit
end
# POST /contacts
# POST /contacts.json
def create
@contact = Contact.new(contact_params)
respond_to do |format|
if @contact.save
FormMailer.message_received(@contact).deliver_now
FormMailer.new_web_message(@email, params).deliver_now
format.html { redirect_to thank_you_path, notice: 'Your message was sent.' }
format.json { render :show, status: :created, location: @contact }
else
format.html { render :new }
format.json { render json: @contact.errors, status: :unprocessable_entity }
end
end
end
# PATCH/PUT /contacts/1
# PATCH/PUT /contacts/1.json
def update
respond_to do |format|
if @contact.update(contact_params)
format.html { redirect_to @contact, notice: 'Contact was successfully updated.' }
format.json { render :show, status: :ok, location: @contact }
else
format.html { render :edit }
format.json { render json: @contact.errors, status: :unprocessable_entity }
end
end
end
# DELETE /contacts/1
# DELETE /contacts/1.json
def destroy
@contact.destroy
respond_to do |format|
format.html { redirect_to contacts_url, notice: 'Contact was successfully destroyed.' }
format.json { head :no_content }
end
end
private
# Use callbacks to share common setup or constraints between actions.
def set_contact
@contact = Contact.find(params[:id])
end
# Never trust parameters from the scary internet, only allow the white list through.
def contact_params
params.require(:contact).permit(:first_name, :last_name, :vehicle_type, :tire_size, :current_tire, :phone_number, :email, :message)
end
end
我在做什麼錯？
