Q&A
ビューはどのように書いていますか？
Active storageを組み込んだ投稿機能を作っているのですが、どうしても投稿ボタンを押すとRoutin errorになってしまいます。
Rails routesをしていたらその部分のパスはないのですが、どうしたら解決できるかわかりません
パスは、No route matches [POST] "/posts/new"です。
教えていただけると幸いです。

そして、以下が投稿に関するcontrollerです
class PostsController < ApplicationController before_action :authenticate_user!, only: [:new, :update, :create, :edit, :update, :destroy] before_action :find_post, only: [:edit, :update, :show, :destroy] def index @posts = Post.all @like = Like.new end def new @like = Like.new end def show end def create @post = current_user @post = Post.create(post_params) if @post.save redirect_to root_path,notice:'投稿に成功しました' else redirect_to new_post_path,notice:'投稿に失敗しました' end end def edit end def update @post.update(post_params) end def destroy if @post.destroy redirect_to root_path,alert: '投稿を削除しました' else redirect_to root_path end end private def post_params params.require(:post).permit(:content, images: []).merge(user_id: current_user.id) end def find_post @post = Post.find(params[:id]) end def force_redirect_unless_my_post return redirect_to root_path,alert:'権限がありません'if @post.user != current_user end end
いかが、投稿に関するmodelです
class Post < ApplicationRecord has_many_attached :images belongs_to :user has_many :likes has_many :liked_users, through: :likes, source: :user validates :content, presence: true end
いかが、投稿に関するviewファイルです
<div class ='post-content'> <%= form_with model: @post, local: true do |f| %> <%= f.text_area :content, :placeholder => "いまどんなカンジ？"%> <%= f.file_field :images, multiple: true%> <div class = 'submit-block'> <%= f.submit '投稿する', class:"button"%> </div> <% end %> </div>

ベストアンサー
PostsController#newで@postを生成していないためにこの値がnilとなり、form_withが正しい送信先を見つけられなくなっているようです。
@post = Post.newとしておきましょう。
