我上面提到的标题是我的任务。当用户输入他当前的密码时，它显示错误，密码不匹配。如何检索当前密码进行比较？我的views/users/_form.html.erb 中的代码如下
<fieldset>
<legend>Enter User Details</legend>
<div>
<%= f.label :name %>:
<%= f.text_field :name, :size => 40 %>
</div>
<% if params[:action ]== "edit" || params[:action]== "update" %>
<div>
<%= f.label :current_password, :class => "long_label" %><br />:
<%= f.password_field :current_password, :size => 40 %>
</div>
<% end %>
<div>
<%= f.label :password, 'Password' %>:
<%= f.password_field :password, :size => 40 %>
</div>
<div>
<%= f.label :password_confirmation, 'Confirm' %>:
<%= f.password_field :password_confirmation, :size => 40 %>
</div>
<div>
<%= f.submit %>
</div>
</fieldset>
我的更新控制器中的代码是
def update
@user = User.find(params[:id])
if @user.authenticate(params[:user][:current_password])
cp = params[:user].delete('current_password')
@user.errors.add(:current_password, 'is not correct') unless @user.authenticate(cp)
respond_to do |format|
if @user.errors.empty? and @user.update_attributes(params[:user])
format.html { redirect_to user_url, :notice => 'Successfully updated.' }
format.json { head :no_content }
else
format.html { render :action => "edit" }
format.json { render :json => @user.errors, :status => :unprocessable_entity }
end
end
end
我的用户模型中的代码如下
class User < ActiveRecord::Base
attr_accessible :name, :password_digest, :password, :password_confirmation, :current_password
# attr_accessor :password validates :name, :presence => true, :uniqueness => true
#validates :current_password, :presence => true
validates :password, :presence =>true
validates_confirmation_of :password, :presence => true
has_secure_password
after_destroy :ensure_an_admin_remains
private
def ensure_an_admin_remains
if User.count.zero?
raise "Can't delete last user"
end
end
end
这是正确的方法吗？如何编写条件以检查以前的密码？它正在询问模板是否有错误。据我所知，错误不需要模板..但这里是问你我不知道！任何帮助肯定会受到赞赏！
