Rails：对象保存在控制台中但不在应用程序中

Question

我知道这一定是某个地方的愚蠢错误，但我一直在兜圈子试图弄清楚为什么我的对象只保存在控制台中，而不保存在应用程序本身中。

有人有想法吗？

代码如下：

控制器：

 class JobsController < ApplicationController
  def index
    @jobs = Job.all
  end

  def new
    @job = Job.new
  end

  def create
    @job = Job.new(job_params)

    if @job.save
      redirect_to jobs_path, flash: { notice: "You've successfully created a job." }
    else
      redirect_to new_job_path, flash: { alert: @job.errors.messages }
    end
  end

  def edit
    @job = Job.find(params[:id])
  end

  def update
    @job = Job.find(params[:id])
    if @job.update
      redirect_to jobs_path, notice: "You've updated a job."
    else
      redirect_to edit_job_path, alert: @job.errors.messages
    end
  end

  def destroy
    @job = Job.find(params[:id])
    if @job.destroy
      redirect_to jobs_path, notice: "You've deleted a job."
    else
      redirect_to jobs_path, alert: @job.errors.messages
    end
  end

  private

  def job_params
    params.require(:job).permit(:poster, :category, :location, :status)
  end
end

和视图：

<h1>Create job</h1>
<form class="form">
  <%= form_for @job do |f| %>
    <%= f.text_field :poster, placeholder: "Poster", onclick: "placeholder = ''", onblur: "placeholder = 'Poster'", autofocus: true, class: "form-group" %><br>
    <%= f.text_field :category, placeholder: "Category", onclick: "placeholder = ''", onblur: "placeholder = 'Category'", class: "form-group" %><br>
    <%= f.text_field :location, placeholder: "Location", onclick: "placeholder = ''", onblur: "placeholder = 'Location'", class: "form-group" %><br>
    <%= f.select :status, ['New', 'Pending', 'Complete'],placeholder: "Status", onclick: "placeholder = ''", onblur: "placeholder = 'Status'", class: "form-group" %><br><br>
    <%= f.submit "Submit", class: "btn btn-secondary" %>
  <% end %>
</div>

和日志：

这条线破坏了你的形式

<form class="form">

HTML 中不能有嵌套表单。因此，您的 form_for 定义中的 <form> 未按应有的方式解释。

此外，还有一个悬挂 </div>。
