resourcesでやっているのにrouting errorになってしまいました

Question

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。

#以下、rails routesの結果です。

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>

了解です。

Answer 1

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。
