rails, authlogic и sql error

1 голос
/ 18 июля 2011

Я пытаюсь построить систему аутентификации с именем admin_name и паролем в рельсах, используя authlogic.Я получаю следующую ошибку:

Mysql :: Error: у вас есть ошибка в вашем синтаксисе SQL;проверьте руководство, соответствующее вашей версии сервера MySQL, чтобы узнать правильный синтаксис для использования рядом с ') =' [admin_name] ') LIMIT 1' в строке 1: SELECT admins. * FROM admins WHERE (LOWER (admins).) = '[admin_name]') LIMIT 1

Это код в admin_session_controller.rb ... 

def login
  @admin_session = AdminSession.new(params[:admin_session])                   
if @admin_session.save
  flash[:notice] = 'Successfuly logged in.'
  redirect_to :controller => 'admins', :action => 'email_stats'
else
  flash[:notice] = 'Trouble!!'
  render :action => 'new'
end
end

Я предполагаю, что это не нравитсяparams[:admin_session], но я не знаю, почему.

шаблон erb .... 

    <%= render :partial => 'layouts/head_admins' %>

<div id="notice">
<% if flash[:notice] %>
<%= flash[:notice] %>
<% end %>
</div>

<div id="main" align="middle">
  <table>
    <%= form_for @admin_session, :as => :admin_session, :url => { :action => "login" } do |f| %>
    <tr class="bold gray">Admin_name</tr>
    <tr id="login_admin_name"><%= f.text_field :admin_name, :class => "text", :tabindex => "1" %></tr>
    <tr class="bold gray">Password</tr>
    <tr id="login_password"><%= f.password_field :password, :class => "password", :tabindex => "2" %></tr>
    <tr><%= image_submit_tag("login_btn.png", :id => 'login_btn', :class=>"image", :tabindex => "3", :alt => 'Login') %></tr>
    <tr class="gray"><%= f.check_box :remember_me %>Keep me logged in</tr>
    <% end %>
  </table>
</div>

Я собираюсь предположить, что вы на самом деле не набирали «[admin_name]» в текстовое поле, а настраивали журналы, которые вы нам показываете?

Вы говорите Authlogic, какое поле использовать для поля входа?Если только это не одно из значений по умолчанию, это может объяснить, почему сгенерированный SQL не содержит фактического имени столбца для сравнения с ... 

SELECT `admins`.* FROM `admins` WHERE (LOWER(`admins`.) = '[admin_name]')
...
