ActiveStorage::DirectUploadsController - Cannot POST /rails/active_storage/direct_uploads

belgoros
I tried to use dire upload way from Ember app to Rails API and used ember-active-storage add-on. Rails responds with the following error when I tried to attach a file:

Cannot POST /rails/active_storage/direct_uploads
404 - Resource was not found.

All Rails controller are protected with before_action filter defined in ApplicationController:

class ApplicationController < ActionController::API



before_action
:authorize_request


  attr_reader
:current_user


 
private


 
def authorize_request
   
@current_user = (AuthorizeApiRequest.new(request.headers).call)[:user]
 
end
end


I inspected the headers used when posting the request, - it seems to be OK and contains Authorization:

Authorization:
Bearer eyJhbG.....



and the request payload:

  1. blob{filename: "Screenshot 2018-10-31 at 10.45.21.png", content_type: "image/png", byte_size: 110466,…}
    1. byte_size110466
    2. checksum"L+1wS2rPR7cKkXP/Rb/rig=="
    3. content_type"image/png"
    4. filename"Screenshot 2018-10-31 at 10.45.21.png"




What's wrong with that ? Thank you.

Here is what I found on the Net and it helped to move forward but there are still some errors:

  • I created DirectUploadsController by extending it from ActiveStorage::DirectUploadsController as follows:
class DirectUploadsController < ActiveStorage::DirectUploadsController
  protect_from_forgery
with: :exception
  skip_before_action
:verify_authenticity_token
end


I defined a new route corresponding to the post request to the above route:

Rails.application.routes.draw do
  resources
:posts
  post
'/rails/active_storage/direct_uploads' => 'direct_uploads#create'
end


I modified the Post serializer as follows:

class PostSerializer < ActiveModel::Serializer
  include
Rails.application.routes.url_helpers


  attributes
:id, :title, :body, :tag_ids, :archived, :photo


 
def photo
    url_for
(object.photo) if object.photo.attached?
 
end
end


Here is Post model:

class Post < ApplicationRecord
  serialize
:tag_ids, Array
  validates
:title, :body, :tag_ids, presence: true


  has_one_attached
:photo
end

And finally PostsController has a new strong_parameter attribute - photo:

def create
   
@post = Post.new(post_params)


   
if @post.save
      render json
: @post, status: :created, location: @post
   
else
      respond_with_errors
@post
   
end
 
end


def post_params
     
ActiveModelSerializers::Deserialization.jsonapi_parse!(params,
        only
: [:title, :body, :tag_ids, :archived, :photo])
end


But when posting a new Post data, there are still errors:
