报出错误为:NameError in AdminController#login
undefined local variable or method `conditions' for #AdminController:0x652edb4

RUBY代码:

app/controllers/.....

class AdminController < ApplicationController

def login
if request.post?
user= User.find(:all, conditions => ["loginName=? and passWord=? and isAdmin='1'",params[:loginName][:passWord]] )
if user
redirect_to(:action=>"index")
else
flash[:notice]="用户名或密码错误，请从新输入！"
end
end
end

end

view/login.....

欢迎进入后台管理系统

<%form_tag do %>

登录名：
<%=text_field_tag:loginName,params[:loginName]%>

密码：
<%=password_field_tag:passWord,params[:passWord]%>

<%=submit_tag "登录"%>

<%end%>

我用的是RAILS2.0以上的版本。谢谢。

[quote]user= User.find(:all, conditions => ["loginName=? and passWord=? and isAdmin='1'",params[:loginName][:passWord]] ) [/quote]
你这代码中，有一点点写错了。conditions前面少了个:号
正确的
[code="ruby"]
user= User.find(:all, :conditions => ["loginName=? and passWord=? and isAdmin='1'",params[:loginName][:passWord]] ) [/code]

[code="ruby]
[size=large]

user= User.find(:all, conditions => ["loginName=? and passWord=? and isAdmin='1'",params[:loginName],params[:passWord])
[/size]
[/code]
