Question

我猜因为参数问题，我无法更新。即使flash表示“更新成功”，也没有任何改变。我使用了User模型和Skill模型，这使事情变得更加复杂。请告诉我如何解决这种情况。

技能控制者：

class SkillsController < UsersController
  def update  
    @skill=Skill.find_by(id:params[:id])

    if @skill.update_attributes(skills_params)
      flash[:success]="Updated Successfully"
      redirect_to users_url
    else
      flash[:danger]="no infomation"
      render @skill
    end
  end

  private

  def skills_params
    params.permit(:id,:skill_type, :tech, :web_name, :web_url, :web_image, :experience)
  end
end

skills / edit.html.erb：

<%= form_for @skill do |f| %>
  <%= f.label:skill_type %>
  <%= text_field :skill_type, value=@skill.skill_type, :placeholder => 
@skill.skill_type %>

  <%= f.label:tech %>
  <%= text_field :tech, value=@skill.tech,:placeholder => @skill.tech %>

  <!-- More fields -->

  <%= f.submit %>
<% end %>

我的猜测是@skill为空。

在edit的{{1}}操作中，您以相同的ID（SkillsController）加载@skill和@user

id:params[:id]

更新不起作用...我猜参数问题
