Ruby on rails - wrong number of arguments (2 for 1) [Rails] - ruby-on-rails

Question

I've just change my database from sqlite3 to postgresql in my Ruby on rails.
Every things worked before but now I have a "wrong number of arguments (2 for 1)" when I submit the form. I don't understand why !
Here my code :
my photo_controller file :
class PhotosController < ApplicationController
before_action :set_photo, only: [:show, :edit, :update, :destroy]
# GET /photos
# GET /photos.json
def index
#photos = Photo.all
end
# GET /photos/1
# GET /photos/1.json
def show
end
# GET /photos/new
def new
#photo = Photo.new
end
# GET /photos/1/edit
def edit
end
# POST /photos
# POST /photos.json
def create
#photo = Photo.new(photo_params)
respond_to do |format|
if #photo.save
format.html { redirect_to #photo, notice: 'Photo was successfully created.' }
format.json { render action: 'show', status: :created, location: #photo }
else
format.html { render action: 'new' }
format.json { render json: #photo.errors, status: :unprocessable_entity }
end
end
end
# PATCH/PUT /photos/1
# PATCH/PUT /photos/1.json
def update
respond_to do |format|
if #photo.update(photo_params)
format.html { redirect_to #photo, notice: 'Photo was successfully updated.' }
format.json { head :no_content }
else
format.html { render action: 'edit' }
format.json { render json: #photo.errors, status: :unprocessable_entity }
end
end
end
# DELETE /photos/1
# DELETE /photos/1.json
def destroy
#photo.destroy
respond_to do |format|
format.html { redirect_to photos_url }
format.json { head :no_content }
end
end
private
# Use callbacks to share common setup or constraints between actions.
def set_photo
#photo = Photo.find(params[:id])
end
# Never trust parameters from the scary internet, only allow the white list through.
def photo_params
params.require(:photo).permit(:image)
end
end
my photo.rb file :
class Photo < ActiveRecord::Base
has_attached_file :image
end
my new.html.erb file ( here is the form and after I chose the image and submit it, I have the error ) :
<h1>New photo</h1>
<%= form_for #photo, :html => { :multipart => true } do |f| %>
<div class="field">
<%= f.file_field :image %>
</div>
<div class="action">
<%= f.submit %>
</div>
<% end %>
my show.html.erb file :
<h1> Je viens de faire un upload ! </h1>
<% if #photo.image? %>

Please help me :)

Answer 1

Looks like you're seeing this error and you should just upgrade Paperclip to the latest version, 3.5.2.
You're running a pretty old paperclip anyway.

Answer 2

Just pulling out the essential pieces from above:
Error:
wrong number of arguments (2 for 1)
Source:
Controller:
1: class PhotosController < ApplicationController
...
24: # POST /photos
25: # POST /photos.json
26: def create
27: #photo = Photo.new(photo_params)
Model:
class Photo < ActiveRecord::Base
has_attached_file :image
end
View:
<%= form_for #photo, :html => { :multipart => true } do |f| %>
<div class="field">
<%= f.file_field :image %>
</div>
<div class="action">
<%= f.submit %>
</div>
<% end %>
