如何在没有当前密码的情况下更改密码？

Question

我正在使用devise进行authentication ，我为每个用户分配一个role ，我允许具有admin角色的用户创建新用户，如果其他用户忘记了密码，我希望管理员用户edit the password密码。 但是我无法在没有当前密码的情况下更改密码。 那么我如何允许管理员用户通过编辑用户密码来更改密码并像我们对其余值一样保存。

Answer 1

由于update_without_password仍然需要current_password来更新密码，因此您必须进行如下update ：

  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

此示例旨在更新当前用户（包括用户密码），但您可以对其进行修改以满足您的需要。

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

Answer 3

有一个内置的设计方法，称为update_without_password 。

这是我在更新方法中使用的内容：

 # 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
