我正在尝试使用文本字段来搜索用户电子邮件，如果找到，则创建会员资格。如果找不到，我想根据电子邮件地址创建用户。

会员/Index.html.erb

<%= render :partial => 'shared/logedinNav' %>
<section class="centered">
  <header>Team Settings</header>
  <section class="main">
    <aside class="blue_nav_aside">
        <nav>
            <ul>
                <li><%= link_to_unless_current "General", team_info_path(:id => @team.id)  %></li>
                <li id="bluenav"><%= link_to_unless_current "Team Members", memberships_path(:id => @team.id) %></li>
                <li><%= link_to_unless_current "Tags & Categories",  %></li>
                <li><%= link_to_unless_current "Payments",  %></li>
            </ul>
        </nav>
    </aside>
    <section class="inline_form">
        <%= form_for @membership do |u|%>
            <% if notice %>
                <p id="notice"><%= notice %></p>
            <% end %>
            <% if alert %>
            <p id="alert"><%= alert %></p>
            <% end %>

            <%= render "shared/error_messages", :target => @membership %>

            <%= u.hidden_field :team_id, :value => @team.id %>
            <h1><span class="pictos pictos-form-h1">g</span>Team Members</h1>
            <%= u.text_field :user_email, :placeholder => "    To add a team member, enter their email here..." %>
            <%= u.submit "Invite", :class => "grey button" %>
            <section>
                <ul>
                    <% @memberships.each do |m|%>
                        <li>
                            <%= m.user.email %>
                            <% if m.team.admin_user_id != m.user_id %>          
                                <%= link_to(membership_path(m), :confirm => 'Are you sure you want to delete this video?', :method => :delete, :class => "red_link") do %>
                                  <span class="pictos pictos-remove">-</span> Remove
                                <% end %>
                            <% end %>
                        </li>
                    <% end %>
                </ul>
            </section>
        <% end %>
    </section>
</section>

Memberships_controller.rb

class MembershipsController < ApplicationController
  def index
    @team = Team.find(params[:id])
    @memberships = Membership.where(:team_id => @team.id)
    @membership = Membership.new
  end
  def create
    @membership = Membership.new(params[:membership])
    @team = Team.find(params[:membership][:team_id])
    @membership.user = User.find_or_create_by_email(:email => params[:membership][:user_email], :password => "pass", :password_confirmation => "pass")

    if @membership.save
      redirect_to memberships_path(:id => @team.id), :notice => "New membership created."
    else
      redirect_to memberships_path(:id => @team.id), :alert => "Fail."
    end
  end
  ....
end

会员资格.rb

class Membership < ActiveRecord::Base
  belongs_to :team
  belongs_to :user
  accepts_nested_attributes_for :user
  attr_accessible :user_id, :team_id
  attr_accessor :user_email

  validates_presence_of :user_id, on: :create
  after_create :set_team_admin

  def set_team_admin
    self.team.set_admin_user
  end
end

它在找到用户时工作，但现在它根本无法识别create_user并跳到失败重定向。

更新：这是更新后的代码，下面提到了建议。

问题是您的成员资格实例不知道 user_email 参数。

您可以使用 Rails 动态查找器方法http://api.rubyonrails.org/classes/ActiveRecord/Base.html#label-Dynamic+attribute-based+finders来创建用户？例如在memberships_controller.rb

def create
    @membership = Membership.new(params[:membership])
    @membership.user = User.find_or_create_by_email(params[:membership][:user_email])

    if @membership.save
      redirect_to memberships_path(:id => @team.id), :notice => "New membership created."
    else
      redirect_to memberships_path(:id => @team.id), :alert => "Fail."
    end
  end
