Ruby on Rails:如何存储表单数据

rails generate model Post title:string content:text

rails db:migrate

<%= form_with(model: @post, local: true) do |form| %>
  <%= form.label :title %>
  <%= form.text_field :title %>

  <%= form.label :content %>
  <%= form.text_area :content %>

  <%= form.submit "Submit" %>
<% end %>

def create
  @post = Post.new(post_params)

  if @post.save
    redirect_to @post
  else
    render 'new'
  end
end

private

def post_params
  params.require(:post).permit(:title, :content)
end
