什么会阻止对象被保存？

时间：2014-07-03 02:58:05

标签： ruby-on-rails object

在我的代码中我有这个：

def confirm
  @pal = Pal.find(params[:palid])
  @newuser = User.new(newuser_params)
  @newuser.username = @pal.phone

  if @newuser.save
    redirect_to(:controller => 'access', :action => 'index')
  else
    flash[:error] = "Retry."
    render template: 'pals/new_password_asign'
  end
end  

private

def newuser_params
  params.require(:newuser).permit(:username, :password_digest, :password_stored)
end

在提交我的注册表单后，我被重定向并出现错误＆＃34;重试＆＃34;我已经指定了。

知道我创建用户并通过rails console完全保存它们。

这让我想到什么可能阻止它被保存？ 保存期间可能会出现什么问题？

我正在使用Bcrypt-ruby进行身份验证。

在添加建议的@mandeep解决方案之后，我现在得到了错误解释，在这个解释中我得到了

＆＃34; 密码不能为空＆＃34;

尽管在提交之前我确实写了密码

检查我的注册表单

<%= form_for(:newuser, :url => {:action => 'confirm', :palid => @pal.id}) do |f| %>
                    <% if @newuser.errors.any? %>
                      <div id="error_explanation">
                        <h2><%= pluralize(@newuser.errors.count, "error") %> prohibited this post from being saved:</h2>

                        <ul>

2 个答案:

答案 0 :(得分：1)

如果你看一下你的代码

def confirm
  pal = Pal.find(params[:palid])  # you have find your pal and store it in "pal"
  @newuser = User.new(newuser_params)
  @newuser.username = @pal.phone  # you are using instance variable "@pal" which is not defined
  # your other logic
end

相反，您应该拥有以下代码：

def confirm
  @pal = Pal.find(params[:palid])  
  @newuser = User.new(newuser_params)
  @newuser.username = @pal.phone
  # your other logic
end

同样在您的表单中，您应该输入此代码

<% if @newuser.errors.any? %>
  <div id="error_explanation">
    <h2><%= pluralize(@newuser.errors.count, "error") %> prohibited this post from being saved:</h2>

    <ul>
      <% @newuser.errors.full_messages.each do |msg| %>
        <li><%= msg %></li>
      <% end %>
    </ul>
  </div>
<% end %>

如果表单中有验证错误，则会显示。有关详细信息，请参阅here

<强>更新

如果您查看从表单传递的参数，请注意

Parameters: {"utf8"=>"✓", "authenticity_token"=>"8X6LD0g6E1HybdAF/FOlM09iuQLWExBY8dY5CqSDZsM=", "newuser"=>{"password"=>"[FILTERED]"}, "commit"=>"Save Newuser", "palid"=>"5"}

您的表单中有几个错误：

一个。要么您没有在表单中输入用户名，要么您还没有正确填写表单，因为在params中它只显示密码字段 "newuser"=>{"password"=>"[FILTERED]"}

湾您尚未准许您的密码字段，而不是允许您允许的密码： password_digest，：password_stored 。您的newuser_params应如下所示：

def newuser_params
  params.require(:newuser).permit(:username, :password)
end

℃。什么是"palid"=>"5"在你的参数中做什么？它是您表单中的字段还是因为它与newuser params

无关

答案 1 :(得分：0)

检查@newuser中的验证错误，即@newuser.errors。有一些方法可以跳过验证。也许你在控制台中使用它们。
