undefined method `images_path' Error in rails

I got an error and I dont know where it come from, this is my code images_controller.rb

class ImagesController < ApplicationController
layout 'home2'
#before_action :set_image, only: [:show, :edit, :update, :destroy]
def crea
@image = Image.new
end

def post
@image = Image.new(params[:images])
end
end


post.html.erb

<h2 align="center">Post your own creation right here !</h2>
<br>
<div align="center">
<%= link_to 'Back', '/showcase', :class => "buttonShow" %>
</div>
<%= simple_form_for @image do |f| %>
<%= f.input :title, :required => true %>
<%= f.input :description, :required => true %>
<%= f.input :nickname, :required => true %>
<%= f.button :submit, "Post !", :class => "buttonShow" %>
<% end %>


routes.rb

Rails.application.routes.draw do
resources "images", only: [:crea, :post]
resources "contacts", only: [:new, :create]
get 'contacts/contact'

get 'images/crea'
get 'images/post'

get 'auth/auth'

root "auth#auth"
#get 'contact' => 'contacts#contact'
get 'showcase' => 'images#crea'
get 'showcase/post' => 'images#post'
#resources "contacts", only: [:new, :create]
# For details on the DSL available within this file, see http://guides.rubyonrails.org/routing.html
end


I got always the same error who don't help me a lot :

undefined method `images_path' for #<#<Class:0x007ffe6c718578>:0x007ffe6c68ab38>
Did you mean? image_alt


The line of code, where the error is supposed to be is according to the ruby error :

<%= simple_form_for @image do |f| %>


this is my models :

class Image < ApplicationRecord
attribute :title, :validate => true
attribute :description, :validate => /\A([\w\.%\+\-]+)@([\w\-]+\.)+([\w]{2,})\z/i
attribute :nickname, :validate => /\A([\w\.%\+\-]+)@([\w\-]+\.)+([\w]{2,})\z/i


end




ActiveRecord::Schema.define(version: 20160927210003) do

create_table "contacts", force: :cascade do |t|
t.string "name"
t.string "email"
t.string "message"
t.datetime "created_at", null: false
t.datetime "updated_at", null: false
end

create_table "images", force: :cascade do |t|
t.string "title"
t.string "description"
t.string "nickname"
t.string "image_filename"
t.datetime "created_at", null: false
t.datetime "updated_at", null: false
end

end


Thank's in advance,
See you soon,

Answer

By default simple_forms search the images_path with POST Method, that means the create action of your controller

But you have this

  resources "images", only: [:crea, :post]
  # Many other code
  get 'images/crea'

You can try changing the resources line to

  resources "images", only: [:crea, :create]

and in your controller

  class ImagesController < ApplicationController
    layout 'home2'
    #before_action :set_image, only: [:show, :edit, :update, :destroy]
    def crea
      @image = Image.new
    end

    def create
      @image = Image.new(params[:images])
    end
  end
