我无法保存 Post。没有路线匹配 [POST] “/posts/new”

Question

希望这些文件足以解决问题。一切正常我只是无法保存 post.

路线：

Rails.application.routes.draw do
  root 'posts#index'
  resources :posts
end

post_controller:

class PostsController < ApplicationController

  def index
    @posts = Post.all
  end

  def show
    @post = Post.find(params[:id])
  end

  def new
    @post = Post.new
  end

  def create
    @post = Post.new(post_params)
    if @post.save
      flash[:notice] = "Successfully created post!"
      redirect_to post_path(@post)
    else
      flash[:alert] = "Error creating new post!"
      render :new
    end
  end

  private

  def post_params
    params.require(:post).permit(:author, :title, :summary, :body)
  end

end

Answer 1

你为 post#new 做了 "GET"，为 post#create 做了 "POST"。新操作旨在 return 所需的表单 "POST" 创建操作。你没有post新动作。

Answer 2

确保您的 Post 表单代码像这样开始：

<%= form_for(@post) do |f| %>

我无法保存 Post。没有路线匹配 [POST] “/posts/new”

I can't save the Post. No route matches [POST] "/posts/new"
