Question

我的表格有问题，我想在我的“会员”表格中创建一个条目，每个成员都连接到“年份”，但我一直选择不匹配的年份。

这是我的表格：

<div class="field">
<%= f.label :name %><br>
<%= f.text_area :name %>
</div>
<div class="field">
<%= f.label :nickname %><br>
<%= f.text_area :nickname %>
</div>
<div class="field">
<%= f.label :year %>
<%= f.select :year, options_for_select(@years.all.map{|y| [y.year,y.id]}) %>
</div>
<div class="actions">
<%= f.submit %>
</div>

以下是模特：

class Member < ApplicationRecord
   belongs_to :year
   mount_uploader :image, ImageUploader
end

class Year < ApplicationRecord
    has_many :members, dependent: :destroy
end

当我尝试提交时，我收到以下错误：

年（＃70050157849460）预期，获得“1”这是一个字符串的实例（＃9412380）

我哪里出错了？

编辑：

以下是控制器的代码

class MembersController < ApplicationController
  def home
    @members = Member.all
  end
  def new
    @member = Member.new
    @years = Year.all
  end
  def create
    @member = Member.new(member_params)
    if @member.save
      flash[:success] = "Member Created"
      redirect_to root_path
    else
      render 'form'
    end
  end

  private

  def member_params
    params.require(:member).permit(:name,:nick,:position,:image,:year)
  end

end

Answer 1

data("WeatherPlay", package = "partykit")

#create a split
sp_o <- partysplit(3L, breaks = 75) 

#create a node
n1 <- partynode(id = 1L, split = sp_o, kids = lapply(2L:3L, partynode))

#and make a "tree" out of it
t2 <- party(
  n1,
  data = WeatherPlay,
  fitted = data.frame(
    "(fitted)" = fitted_node(n1, data = WeatherPlay),
    "(response)" = WeatherPlay$play,
    check.names = FALSE
  ),
  terms = terms(play ~ ., data = WeatherPlay),
)

t2 <- as.constparty(t2)
t2
plot(t2)

或

<div class="field">
<%= f.label :name %><br>
<%= f.text_area :name %>
</div>
<div class="field">
<%= f.label :nickname %><br>
<%= f.text_area :nickname %>
</div>
<div class="field">
<%= f.label :year %>
<%= f.select :year_id, options_for_select(@years.all.map{|y| [y.year,y.id]}) %>
</div>
<div class="actions">
<%= f.submit %>
</div>

这第二个我没有检查但是首先会工作你需要说year_id因为当你在集合上映射时你将id设置为正在传递的参数但是在表单上选择你基本上告诉表单期待活动记录对象。

关联时键入不匹配，f。选择rails
