我有點新的Ruby on Rails和StackOverflow。我有一個Rails應用程序,人們可以在名單上簽名。但我想發送電子郵件通知給名單中第二位的人。我怎樣才能做到這一點?我需要一個if語句嗎?我如何讓鐵軌知道誰是第二?如果客戶端在Ruby on Rails的列表中處於第二位,如何發送電子郵件通知?
這裏是我的名單控制器:
class ListsController < ApplicationController
before_action :find_list, only: [:show, :edit, :update, :destroy]
def index
@list = List.all.order("created_at asc")
end
def new
@list = List.new
end
def create
@list = List.new list_params
if @list.save
redirect_to root_path, notice: "#{@list.name}, You have been added to the List!"
else
render 'new', notice: "Oh No! Not Saved!"
end
end
def show
end
def edit
end
def update
if @list.update list_params
redirect_to @list, notice: "#{@list.name}, has been updated!"
else
render 'edit'
end
end
def destroy
@list.destroy
redirect_to root_path, notice: "#{@list.name}, has been deleted!"
end
private
def list_params
params.require(:list).permit(:name, :barber_id)
end
def find_list
@list = List.find(params[:id])
end
end
這是我的形式
<%= form_for @list do |f| %>
<% if @list.errors.any?%>
<h2><%= pluralize(@list.errors.count, "error") %> prevented this list from saving:</h2>
<ul>
<% @list.errors.full_messages.each do |msg| %>
<li><%= msg %></li>
<%end%>
</ul>
<%end%>
<div class="form-group ">
<%= f.label :name %>
<%= f.text_field :name, {class: 'form-control'} %>
</div>
<div class="form-group">
<%= f.label "Choose a Barber" %>
<!-- :include_blank => true
insert this to have the option of leaving it blank
-->
<div class="classic-select">
<%= f.collection_select :barber_id, Barber.all, :id, :name %>
</div>
</div>
<br>
<button type="submit" class="btn-add-to-list">Submit</button>
<%end%>
這裏是我的index.html.erb
<div class="container">
<div class="row">
<div class="col-md-10 list center-block">
<% @list.each do |list| %>
<div class="col-md-6 names panel-default panel">
<h1><%= link_to list.name, list %></h1>
<p><strong>Barber:</strong> <%= list.barber.name %></p>
<hr>
</div>
<%end%>
<div class="col-md-2 center-block">
<%= link_to "Add Me to the List", new_list_path, class: "btn-add btn"%>
</div>
</div>
</div>
</div>
真棒傢伙!非常感謝!所以現在我只是在我的if語句中使用變量來發送我的電子郵件 – Bryan
