我的表格包含:
我不确定这是否是最佳设计,但该模型包含三个属性:
如果填写了两个复选框中的任何一个,我想保存电子邮件地址,否则不保存任何内容。
一切看起来都像我预期的那样,但是一旦我查看了rails控制台,注册模型就是空的。
我的日志文件说明了这个:
Started POST "/pages" for 127.0.0.1 at 2012-02-01 16:34:55 -0500
Processing by PagesController#create as HTML
Parameters: {"utf8"=>"✓", "authenticity_token"=>"WChW/OmDPS2Td1D3x/36aCJj7V75FdiAPJ9AQvtAIS4=", "post"=>{"email_address"=>"email@examp.le", "send_once"=>"0", "send_any_time"=>"1"}, "commit"=>"Create Signup"}
(0.3ms) BEGIN
(0.5ms) SELECT 1 FROM "signups" WHERE "signups"."email_address" = '' LIMIT 1
(0.3ms) ROLLBACK
Rendered pages/_form.html.erb (3.7ms)
我该如何解决这个问题?目前该模型没有保存。那么,特别是模型和控制器应该是什么样的?
注意:我在Pages控制器内创建一个signup
对象(想想:简报)。
控制器的
class PagesController < ApplicationController
def index
@signup = Signup.new
end
def create
@signup = Signup.new(params[:signup])
respond_to do |format|
if @signup.save
format.html
#format.js
else
format.html {render action: :index}
end
end
end
end
模型
class Signup < ActiveRecord::Base
attr_accessible :email_address
# email_regex = come up with something
validates :email_address, presence: true,
#format: {with: email_regex}, uniqueness: {message: 'there can only be one you.'}
end
_ form.html.erb
<%= form_for(@signup, as: :post, url: pages_path) do |f| %>
<% if @signup.errors.any? %>
<div id="error_explanation">
<p><%= pluralize(@signup.errors.count, "error") %> prohibited this post from being saved:</p>
<ul>
<% @signup.errors.full_messages.each do |user| %>
<li><%= user %></li>
<% end %>
</ul>
</div>
<% end %>
<div class="field">
<%= f.label :email_address %><br />
<%= f.email_field :email_address %>
<%= f.label :send_once %><br />
<%= f.check_box :send_once %>
<%= f.label :send_any_time %><br />
<%= f.check_box :send_any_time %>
</div>
<div class="actions">
<%= f.submit %>
</div>
<% end %>
答案 0 :(得分:1)
你的参数被传递为:post和你的create语句正在寻找params [:signup]。您需要更改控制器以查找params [:post]或更改表单以提交给params [:signup]。
<%= form_for(@signup, as: :signup, url: pages_path) do |f| %>
您还需要检查复选框是否已选中 假设您的参数是:
"signup"=>{"email_address"=>"email@examp.le", "send_once"=>"0", "send_any_time"=>"1"}
你想做的事:
class PagesController < ApplicationController
def index
@signup = Signup.new
end
def create
@signup = Signup.new(params[:signup])
if @signup.send_once == "1" or @signup.send_any_time == "1" then
respond_to do |format|
if @signup.save
format.html
else
format.html {render action: :index}
end
end
else
# what do you want to do if they didn't sign up? redirect somewhere?
end
end
end
