Question

我正在为糖尿病患者编写一个应用程序来计算人们需要的胰岛素。这意味着用户个人资料包括他的姓名电子邮件和密码，以及一天中不同时间的因素。数据库架构是：

ActiveRecord::Schema.define(version: 20180115094430) do

  create_table "users", force: :cascade do |t|
    t.string "name"
    t.string "email"
    t.datetime "created_at", null: false
    t.datetime "updated_at", null: false
    t.string "password_digest"
    t.string "remember_digest"
    t.boolean "admin"
    t.string "activation_digest"
    t.boolean "activated"
    t.datetime "activated_at"
    t.string "reset_digest"
    t.datetime "reset_sent_at"
    t.float "zero_till_one"
    t.float "one_till_two"
    t.float "two_till_three"
    t.float "three_till_four"
    t.float "four_till_five"
    t.float "five_till_six"
    t.float "six_till_seven"
    t.float "seven_till_eight"
    t.float "eight_till_nine"
    t.float "nine_till_ten"
    t.float "ten_till_eleven"
    t.float "eleven_till_twelve"
    t.float "twelve_till_thirteen"
    t.float "thirteen_till_fourteen"
    t.float "fourteen_till_fifteen"
    t.float "fifteen_till_sixteen"
    t.float "sixteen_till_seventeen"
    t.float "seventeen_till_eightteen"
    t.float "eightteen_till_nineteen"
    t.float "nineteen_till_twenty"
    t.float "twenty_till_twentyone"
    t.float "twentyone_till_twentytwo"
    t.float "twentytwo_till_twentythree"
    t.float "twentythree_till_zero"
  end

end

当我创建用户时，他只是使用姓名，电子邮件和密码创建的。注册并登录后，用户可以通过RESTful routes user / 1 / edit编辑他的个人资料。我希望用户能够通过user / 1 / edit / diabsettings编辑仍为空的t.float“zero_till_one”等列，并且仍然可以在users_controller.rb中使用相同的更新操作来更新数据库： / p>

def update
    @user = User.find(params[:id])
    if @user.update_attributes(user_params)
      flash[:success] = "Profile updated"
      redirect_to @user

    else
      render 'edit'
    end
  end

我怎样才能做到这一点。任何帮助高度赞赏。

Answer 1

1-创建编辑操作

    COUNT
1
1
1
0
1
0

2- edit.html.erb

def edit
  @user = User.find(params[:id])
end

3 - 创建edit_diabsettings动作

<%=form_for @user, :html => { id: "edit_user", class: "your_class"} do |f|%>
  <%=f.text_field :name, class: 'form-control'%>
  <%=f.text_field :email,class: 'form-control'%>
  <%=f.text_field :password,class: 'form-control'%>
  <% content_tag :button, :type => :submit, class: 'btn btn-primary' do %>
    Update User
  <% end %>
<%end%>

4- in edit_diabsettings.html.erb craete form to edit name to name，email，password： -

  def edit_diabsettings
    @user = User.find(params[:id])
  end

5-进行更新操作以更新所有字段

<%=form_for @user, :html => { id: "edit_diabsettings", class: "your_class"} do |f|%>
  <%=f.text_field :zero_till_one, class: 'form-control'%>
  <%=f.text_field :one_till_two,class: 'form-control'%>
  <%=f.text_field :two_till_three,class: 'form-control'%>

  #.... and so on that should be editable here
  <% content_tag :button, :type => :submit, class: 'btn btn-primary' do %>
    Update User
  <% end %>
<%end%>

6-为user_params创建一个私人行动

def update
    @user = User.find(params[:id])
    if @user.update(user_params)
      flash[:success] = "Profile updated"
      redirect_to @user
    else
      render 'edit'
    end
  end

7-因为您需要在routes.rb

中为

private

    def user_params
      params.require(:user).permit!
    end

操作创建单独的操作

edit_diabsettings

Rails 5个多个编辑视图，用于一个更新控制器操作
