PDF upload Ruby on Rails server - DB Postgres - ruby-on-rails

Question

Hello I am trying to store a PDF document in a PostgreSQL database using Ruby Rails.
Currently my code looks like this:
DB File:
'$20151126021922_create_pdf_creates.rb'
class CreatePdfCreates < ActiveRecord::Migration
def change
create_table :pdf_creates do |t|
t.binary :pdfload
t.timestamps null: false
end
end
end
Model:
'$pdf_create.rb'
class PdfCreate < ActiveRecord::Base
end
Controller:
'$pdf_creates_controller.rb'
class PdfCreatesController < ApplicationController
before_action :set_pdf_create, only: [:show, :edit, :update, :destroy]
# GET /pdf_creates
# GET /pdf_creates.json
def index
#pdf_creates = PdfCreate.all
end
# GET /pdf_creates/1
# GET /pdf_creates/1.json
def show
end
# GET /pdf_creates/new
def new
#pdf_create = PdfCreate.new
end
# GET /pdf_creates/1/edit
def edit
end
# POST /pdf_creates
# POST /pdf_creates.json
def newpdf
#pdf_create = PdfCreate.new(pdf_create_params)
respond_to do |format|
if #pdf_create.save
format.html { redirect_to #pdf_create, notice: 'Pdf create was successfully created.' }
format.json { render :show, status: :created, location: #pdf_create }
else
format.html { render :new }
format.json { render json: #pdf_create.errors, status: :unprocessable_entity }
end
end
end
def create
#pdf_create = PdfCreate.new(pdf_create_params)
#data = File.read(Rails.root + "tmp/consent(1).pdf")
#Document.create pdfload: data
respond_to do |format|
if #pdf_create.save
format.html { redirect_to #pdf_create, notice: 'Pdf create was successfully created.' }
format.json { render :show, status: :created, location: #pdf_create }
format.pdf { send_data #pdf_create.render}
else
format.html { render :new }
# format.json { render json: #pdf_create.errors, status: :unprocessable_entity }
end
end
end
# PATCH/PUT /pdf_creates/1
# PATCH/PUT /pdf_creates/1.json
def update
respond_to do |format|
if #pdf_create.update(pdf_create_params)
format.html { redirect_to #pdf_create, notice: 'Pdf create was successfully updated.' }
format.json { render :show, status: :ok, location: #pdf_create }
else
format.html { render :edit }
format.json { render json: #pdf_create.errors, status: :unprocessable_entity }
end
end
end
# DELETE /pdf_creates/1
# DELETE /pdf_creates/1.json
def destroy
#pdf_create.destroy
respond_to do |format|
format.html { redirect_to pdf_creates_url, notice: 'Pdf create was successfully destroyed.' }
format.json { head :no_content }
end
end
private
# Use callbacks to share common setup or constraints between actions.
def set_pdf_create
#pdf_create = PdfCreate.find(params[:id])
end
# Never trust parameters from the scary internet, only allow the white list through.
def pdf_create_params
params.require(:pdf_create).permit(:pdfload)
end
end
I send a pdf form and the result that is returned is me:
{"id":5,"pdfload":null,"created_at":"2015-11-26T03:24:37.457Z","updated_at":"2015-11-26T03:24:37.457Z"}
What is wrong? Tks

Answer 1

You're sending the whole newly created record, not the PDF data stored in it.
Try changing this:
format.pdf { send_data #pdf_create.render}
to this:
format.pdf { send_data #pdf_create.pdfload}
