如何在设计中更改没有当前密码的密码？

Question

我使用devise为authentication和我有每个用户的role，我允许与admin角色的用户创建新的用户，我想管理员用户edit the password为用户剩下的，如果他们忘记了自己的密码。但是我无法在编辑中改变没有当前密码的密码。那么我怎样才能允许管理员用户通过编辑用户密码来改变密码，并像我们为其余的值一样保存。

有一个方法内置设计称为update_without_password。

下面是我用我的更新方法是什么：

# PUT /manage_users/1 
    # PUT /manage_users/1.json 
    def update 
    @user = User.find(params[:id]) 
    able_to_edit_profile? 

    # required for settings form to submit when password is left blank 
    if params[:user][:password].blank? 
     params[:user].delete("password") 
     params[:user].delete("password_confirmation") 
    end 

    respond_to do |format| 
     if @user.update_attributes(params[:user]) 
     @user.save   

     # sign the user in with their new password so it doesn't redirect to the login screen 
     sign_in @user, :bypass => true 

     format.html { 
      flash[:notice] = 'User was successfully updated.' 
      redirect_to session.delete(:return_to) 
     } 
     format.json { head :no_content } 
     else 
     format.html { render action: "edit", notice: 'Error updating user.' } 
     format.json { render json: @user.errors, status: :unprocessable_entity } 
     end 
    end 
    end 

private 

    # If the user is not an admin and trying to edit someone else's profile, redirect them 
    def able_to_edit_profile? 
    if !current_user.try(:admin?) && current_user.id != @user.id 
     flash[:alert] = "That area is for administrators only." 
     redirect_to :root 
    end 
    end

由于update_without_password仍然需要current_password更新密码，你就必须有一个update这样的：

def update 
    # required for settings form to submit when password is left blank 
    if params[:user][:password].blank? 
     params[:user].delete("password") 
     params[:user].delete("password_confirmation") 
    end 

    @user = User.find(current_user.id) 
    if @user.update_attributes(params[:user]) 
     set_flash_message :notice, :updated 
     # Sign in the user bypassing validation in case his password changed 
     sign_in @user, :bypass => true 
     redirect_to after_update_path_for(@user) 
    else 
     render "edit" 
    end 
    end 

这示例用于更新当前用户（包括用户的密码），但您可以对其进行修改以适应您的需求。

@user.update_attributes(password: params[:user][:password])
