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

Question

Hope that this files is enough to solve the problem. All is working I just can't save the post.

routes:

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

`new` is supposed to be for `get` requests not posts(POST request). — fanta, Mar 09 '17 at 18:45

You do "GET" for post#new and a "POST" for post#create. The new action is designed to return the form required to "POST" to the create action. You don't post to the new action.

I'm new to ROR. How can I fix it? – Артем Неймышев Mar 09 '17 at 19:16
How are you going to your post new ? You should have a link that looks like this: new_post_path – Alexander Luna Mar 09 '17 at 19:40
I have it in index.html.erb – Артем Неймышев Mar 09 '17 at 19:45
<%= link_to 'New post', new_post_path %> – Артем Неймышев Mar 09 '17 at 19:45
Add your "rake routes" output. Did you restart your server ? Also post the form in your new.html file – Alexander Luna Mar 09 '17 at 20:00
Yes I restart server. Yes form in new.html.erb. – Артем Неймышев Mar 09 '17 at 20:11

Please post the form in your new.html. I think the issue is there. Your routes look good. – Alexander Luna Mar 09 '17 at 20:13
New Post <%= form_for :post do |f| %>
<%= f.label :author %>
<%= f.text_field :author %>

<%= f.label :title %>
<%= f.text_field :title %>

<%= f.label :summary %>
<%= f.text_area :summary %>

<%= f.label :body %>
<%= f.text_area :body %>

<%= f.submit %>
<% end %> – Артем Неймышев Mar 09 '17 at 20:22
Change your form to: "form_for @post do |f|". – Alexander Luna Mar 09 '17 at 21:46

Make sure your Post form code starts like this:

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

<%= form_for :post do |f| %> – Артем Неймышев Mar 09 '17 at 20:45
change it to <%= form_for(@post) do |f| %> and see what happens. Form helpers take name of instance variable - here "@post" as a parameter.. Read more about form helpers here: http://guides.rubyonrails.org/form_helpers.html – Tomasz Bubała Mar 09 '17 at 20:47
ahahashah I don't know how – Артем Неймышев Mar 09 '17 at 21:01
