Question

我目前正在编写代码，为每个登录我的应用程序的用户构建一个配置文件页面。但是我花了很多时间，似乎无法想出这个。请原谅我缺乏知识，我是初学者，现在还在学习。

以下是构建初始个人资料页面的用户模型的一部分：

  has_one :profile

  after_create :build_profile

  def build_profile
    Profile.create(user: self)
  end

在我的Profiles_controller.rb

中

before_action :find_profile, only: [:show, :edit, :update, :destroy]
before_action :authenticate_user!, except: [:index, :show]

def index
  @profile = Profile
end

def show
  @profile = Profile.find(profile_params)
end


def edit
  @profile = Profile.find(params[:id])
end

def update
  @profile = Profile.find(params[:id])
  @profile.update(profile_params)
end

private

def find_profile
  @profile = Profile.find(params[:id])
end

def profile_params
  params.permit(:profile).permit(:name, :summary, :birthday, :user_id)
end

这是我的edit.html.erb

 <%= simple_form_for @profile do |f| %>
  <%= f.input :name %>
  <%= f.date_select :birthday %>
  <%= f.text_field :summary %>
  <%= f.button :submit, 'Save', class: 'submit' %>
 <% end %>

当我导航到个人资料/ 28 /编辑时，我会收到相应的表格。但是在保存表单时，我的数据库不会使用我提供的属性进行更新。任何方向，帮助或提示将不胜感激。如果需要任何进一步的信息，请告诉我。先感谢您！

Answer 1

这里的问题是日志中显示的未允许的参数。

Unpermitted parameters: utf8, _method, authenticity_token, profile, commit, id

底部profile_params的方法应更改为，

def profile_params
  params.require(:profile).permit(:id,:name, :summary, :birthday, :user_id)
end

Answer 2

尝试使用update_attributes方法

def update
  @profile = Profile.find(params[:id])
  @profile.update_attributes(profile_params)
end
