Rails 4 の Rails 初心者です。ワイナリーの名前とボトルの年を取るワインリストを作成しようとしています。これが私のフォームです
<%= form_for @wine do |f| %>
<%# render "errors", object: @wine %>
<div class="form-group input-group input-group-lg">
<%= f.text_field :name, placeholder: "Enter the winery name", class: "form-control input-lg" %>
</div>
<div class="form-group input-group input-group-lg">
<%= select_year(Date.today, start_year: Time.now.year, end_year: Time.now.year - 90, field_name: :year, prefix: :wine) %>
</div>
<div class="form_group input-group">
<%= f.submit "Add wine", class: "btn btn-success" %>
</div>
<% end %>
これが私のコントローラーです
class WinesController < ApplicationController
before_action :set_wine, only: [:show, :edit, :update, :destroy]
def index
@wines = Wine.all
end
def new
@wine = Wine.new
end
def create
@wine = Wine.new(wine_params)
if @wine.save
flash[:notice] = "Successfully created..."
redirect_to @wine
else
flash.now[:error] = "There was a problem"
render "new"
end
end
def show
end
def edit
end
def update
if @wine.update(wine_params)
redirect_to @wine
else
flash[:error] = "Something went wrong"
render "edit"
end
end
def destroy
@wine.destroy
redirect_to wines_path
end
private
def set_wine
@wine = Wine.find(params[:id])
end
def wine_params
params.require(:wine).permit(:name, :year)
end
end
name:string 列と year:datetime 列を持つ wines テーブルがあります
新しいワインを作成しようとするたびに、argument out of range
例外が発生@wine = Wine.new(wine_params)
し、作成アクションで強調表示されます。私は何を間違っていますか?
