ルーティングエラー発生 No route matches [POST] "/categories/new"が解決できません。ご教示お願い致します。

Question

現在、カテゴリー新規作成機能を実装しています。
form_withを使用してデータを受け取りたいです。

new.html.erb

<%= form_with modle: @category, url: categories_path do |f| %>
　<%= f.label :category_name, "カテゴリー名", class: "control-label" %>
　<span class="badge badge-danger">必須</span>
　　<%= f.text_field :category_name, class: "form-control" %>
　　　<%= f.submit '登録', class: "btn btn-primary assignMenber" %>
<% end %>

routes.rb

Rails.application.routes.draw do
  get 'tasks/new' => 'tasks#new'
  devise_for :users
  root 'homes#index'
  resources :users
  resources :tasks, only: [:index]
  resources :categories, only: [:index, :new, :create, :destroy, :edit, :search] do
    collection do
      get 'search'
    end
  end
end

categories_controller.rb

class CategoriesController < ApplicationController
  def index
    @category = Category.all
    # binding.pry
  end

  def new
    @category = Category.new
  end

  def create
    binding.pry
    @category = Category.new(category_params)
    @category.save
    redirect_to categories_path
  end

  def destroy
    @category = Category.find(params[:id])
    @category.destroy
    redirect_to categories_path
  end

  def edit
    @category = Category.find(params[:id])
    binding.pry
    reirect_to new_category_path
  end

  def search
    @category = Category.find_by('category_name LIKE(?)', "%#{params[:keyword]}%")
    render json: @category
  end

  private
  def category_params
    params.require(:categories).permit(:category_name)
  end

end

何をしたときに
No route matches [POST] "/categories/new"
が表示されるのでしょうか

[takuya861]

submitの登録ボタンを押した時です！

[naokit-dev]

[POST] "/categories/new
に違和感を感じます

通常createに対応するのはPOST /categoriesではないでしょうか？

[takuya861]

私もそう思い、色々調べてみたんですが中々解決に至らず。
どこをどうしたらPOST /categoriesになるのかがわかりませんでした。

[naokit-dev]

rails routes
の結果を追記していただけますか

[takuya861]

routesを追記しました！

[naokit-dev]

ルーティングは正しいですね
POST /categories(.:format) categories#create

[takuya861]

やはり、form_withの記述がおかしいのでしょうか？

[naokit-dev]

submitを押して以降の
rails serverのlogを見ることはできますか？

[naokit-dev]

formページのリロード
rails serverの再起動も試してみてください

こちらの現象によく似ています

[takuya861]

formページのリロード、サーバーの再起動も試しましたが同じエラーが出ました！

Answer 1

<%= form_with modle: @category, url: categories_path do |f| %>

を以下のうようにするといかがでしょうか？

<%= form_with modle: @category do |f| %>

もしくは

<%= form_with url: categories_path do |f| %>

もしくは

Ajax無効

<%= form_with modle: @category, local: true do |f| %>

同じ結果になります。
最初は上記のように書いていたのですが、作成後にカテゴリー管理画面（index.html.erb)に飛ばしたかったので追記しました！

[naokit-dev]

form_with url...
はformの送信先urlになると思います

よってご希望の動作をするには
form_with のurl記述は不要で

controller内のredirectのみで良いと思います

[takuya861]

urlは消しておきます！

[takuya861]

同じエラー文がでますね。。。

[takuya861]

これも同じ結果でした！

[naokit-dev]

あまりお役に立てず申し訳ないです

もし可能でしたら解決法など残していただけると他の方の役にも立つかと思います。

[takuya861]

いえいえ！
こちらですが、new.html.erbの内容が長いので抜粋したものだったのですが抜粋した箇所以外のところが問題でした。

原因はマークアップした際の<form>タグが残っていたのが原因でした！

お手数をおかけしました。。。
