Question

这就是在我的模型中调用我想要的错误的方法：

validate :number_of_clients

def number_of_clients
      errors[:base] << "You cannot add another client" if
        Authorization.current_user.plan.num_of_clients <= Authorization.current_user.clients.count 
end

即使我将错误行更改为以下内容，也会产生相同的结果：

errors.add(:base, "You cannot add another client")
errors.add_to_base("You cannot add another client")

这是解析错误消息的方式（在_error_messages部分中）：

<% if object.errors.any? %>
    <div id="error_explanation">
        <h2><%= pluralize(object.errors.count, "error") %>
            prohibited this user from being saved:</h2>
    <p> There were problems with the following fields:</p>
    <ul>
        <% object.errors.full_messages.each_full do |msg| %>
            <li><%= msg %></li>
        <% end %>   
    </ul>
    </div>
<% end %>

这是我的html中显示错误消息的方式：

There were errors: base: You cannot
add another client

编辑1：我想要发生的是在实际消息中删除文本“base：”。所以我想说There were errors: You cannot add another client。

Answer 1

尝试

errors.add_to_base("Your message")

Answer 2

    validate :number_of_clients

    def number_of_clients
      errors.add(:base, "You cannot add another client") if Authorization.current_user.plan.num_of_clients <= Authorization.current_user.clients.count 
      errors.blank? #You have to return false to not proceed

    end

if：base出现，为什么你不尝试这样做：

MyClass < ActiveRecord::Base

  attr_reader :my_mistery_field

  validate :number_of_clients

  def number_of_clients
    errors.add(:my_mistery_field, "You cannot add another client") if Authorization.current_user.plan.num_of_clients <= Authorization.current_user.clients.count 
    errors.blank? #You have to return false to not proceed
  end


end

在您的文件en.yml（或lang.yml，无论您的lang默认应用程序）

en.yml

en:
  activerecord:
    attributes:
      my_class:
        my_mistery_field:   "Don't touch on my mistery field"

当然用于其他事情，但谁告诉我们不能欺骗Rails？

希望它能以某种方式帮助你。

Answer 3

我通过在base: ""文件中的activerecord.attributes下的相应位置添加条目en.yml来解决此问题。

如何从Rails 3中的错误消息中删除“base：”这个词？
