问题
I am pretty new to API in Rails, although I have gotten some assistance already about how to structure my HTTParty Post Request, but the payload (data) that I am sending does not impact on the database of my API
All I want is to create a record on the database of the API through a POST request from my application.
That is to create a record on both databases (my database and the on the database of the API through a POST request from my application) whenever I create a book.
For the app that will consume the API I am using the HTTParty gem, but the request only runs on the without impacting the database of the API
Here is my HTTParty Post Request Code
@result = HTTParty.post(' https://www.pingme.com/wp-json/wplms/v1/user/register',
:body => {
:books => {
:name => '#{name}',
:author => '#{author}',
:description => '#{description}',
:category_id => '#{category_id}',
:sub_category_id => '#{sub_category_id}'}.to_json,
:headers => { 'Content-Type' => 'application/json', 'Authorization' => '77d22458349303990334xxxxxxxxxx' })
But this does not impact on the database of the API, rather it only impacts on the database of my Rails Application
Here is the log code for the execution
Started POST "/books" for 127.0.0.1 at 2019-03-27 11:51:18 +0100

↳ app/controllers/books_controller.rb:32
(77.8ms) commit transaction
I cannot find any log for @result in my terminal, still wondering if it was skipped or didn't run at run, or there is a better way to do it.
Please I need some help on how to parse in ruby to be posted to the database of the API.
Here is my Books Controller for creating books
require 'httparty'
class BooksController < ApplicationController
include HTTParty
before_action :set_book, only: [:show, :edit, :update, :destroy]
before_action :authenticate_admin!, except: %i[show index]
skip_before_action :verify_authenticity_token
# GET /books
# GET /books.json
def index
@books = Book.search(params[:keywords]).paginate(:page => params[:page], :per_page => 9).order('created_at DESC')
end
# GET /books/1
# GET /books/1.json
def show
end
# GET /books/new
def new
@book = Book.new
end
# GET /books/1/edit
def edit
end
# POST /books
# POST /books.json
def create
@book = Book.new(book_params)
respond_to do |format|
if @book.save
format.html { redirect_to @book, notice: 'Book was successfully created.' }
format.json { render :show, status: :created, location: @book }
else
format.html { render :new }
format.json { render json: @book.errors, status: :unprocessable_entity }
end
end
@result = HTTParty.post(' https://www.pingme.com/wp-json/wplms/v1/user/register',
:body => {
:books => {
:name => '#{name}',
:author => '#{author}',
:description => '#{description}',
:category_id => '#{category_id}',
:sub_category_id => '#{sub_category_id}'}.to_json,
:headers => { 'Content-Type' => 'application/json', 'Authorization' => '77d22458349303990334xxxxxxxxxx' })
end
# PATCH/PUT /books/1
# PATCH/PUT /books/1.json
def update
respond_to do |format|
if @book.update(book_params)
format.html { redirect_to @book, notice: 'Book was successfully updated.' }
format.json { render :show, status: :ok, location: @book }
else
format.html { render :edit }
format.json { render json: @book.errors, status: :unprocessable_entity }
end
end
end
# DELETE /books/1
# DELETE /books/1.json
def destroy
@book.destroy
respond_to do |format|
format.html { redirect_to books_url, notice: 'Book was successfully destroyed.' }
format.json { head :no_content }
end
end
private
# Use callbacks to share common setup or constraints between actions.
def set_book
@book = Book.find(params[:id])
end
# Never trust parameters from the scary internet, only allow the white list through.
def book_params
params.require(:book).permit(:name, :author, :description, :category_id, :sub_category_id)
end
end
Please any form of assistance will be highly appreciated. Thank you.

@result is never called in your controller because the redirect happens before the execution gets there.
I would wrap the HTTP call in a method rather than assign it to an instance variable since it is transacting things, not assigning them then bring it inside you format.html {} block. Something like this:
def create
@book = Book.new(book_params)
respond_to do |format|
if @book.save
format.html {
post_to_api
redirect_to @book, notice: 'Book was successfully created.'
}
format.json { render :show, status: :created, location: @book }
else
format.html { render :new }
format.json { render json: @book.errors, status: :unprocessable_entity }
end
end
end
private
def post_to_api
HTTParty.post(' https://www.pingme.com/wp-json/wplms/v1/user/register',
:body => {
:books => {
:name => "#{@book.name}",
:author => "#{@book.author}",
:description => "#{@book.description}",
:category_id => "#{@book.category_id}",
:sub_category_id => "#{@book.sub_category_id}"}.to_json,
:headers => {
'Content-Type' => 'application/json',
'Authorization' => '77d22458349303990334xxxxxxxxxx'
}
)
end

Following contributions from @vincent-rolea and @oneWorkingHeadphone, I found a working solution to the issue.
Here is the corrected HTTParty Post Request that worked for me.
@results = HTTParty.post(' https://www.pingme.com/wp-json/wplms/v1/user/register',
:body => {
:name => "#{@book.name}",
:author => "#{@book.author}",
:description => "#{@book.description}",
:category_id => "#{@book.category_id}",
:sub_category_id => "#{@book.sub_category_id}"}.to_json,
:headers => {
'Content-Type' => 'application/json',
'Authorization' => '77d22458349303990334xxxxxxxxxx'
}
)
Ensure to do the following to make to work
- Install and confgure the HTTParty gem in your application
- Include and require the HTTParty gem in the controller where you want the request to be performed
- Pass the HTTParty gem post request to an instance variable of in that controller
Here is the inplementation of the HTTParty Post Request in my controller
require 'httparty'
class BooksController < ApplicationController
include HTTParty
before_action :set_book, only: [:show, :edit, :update, :destroy]
before_action :authenticate_admin!, except: %i[show index]
skip_before_action :verify_authenticity_token
# GET /books
# GET /books.json
def index
@books = Book.search(params[:keywords]).paginate(:page => params[:page], :per_page => 9).order('created_at DESC')
end
# GET /books/1
# GET /books/1.json
def show
end
# GET /books/new
def new
@book = Book.new
end
# GET /books/1/edit
def edit
end
# POST /books
# POST /books.json
def create
@book = Book.new(book_params)
respond_to do |format|
if @book.save
format.html { redirect_to @book, notice: 'Book was successfully created.' }
format.json { render :show, status: :created, location: @book }
else
format.html { render :new }
format.json { render json: @book.errors, status: :unprocessable_entity }
end
end
@results = HTTParty.post(' https://www.pingme.com/wp-json/wplms/v1/user/register',
:body => {
:name => "#{@book.name}",
:author => "#{@book.author}",
:description => "#{@book.description}",
:category_id => "#{@book.category_id}",
:sub_category_id => "#{@book.sub_category_id}"}.to_json,
:headers => {
'Content-Type' => 'application/json',
'Authorization' => '77d22458349303990334xxxxxxxxxx'
}
)
end
# PATCH/PUT /books/1
# PATCH/PUT /books/1.json
def update
respond_to do |format|
if @book.update(book_params)
format.html { redirect_to @book, notice: 'Book was successfully updated.' }
format.json { render :show, status: :ok, location: @book }
else
format.html { render :edit }
format.json { render json: @book.errors, status: :unprocessable_entity }
end
end
end
# DELETE /books/1
# DELETE /books/1.json
def destroy
@book.destroy
respond_to do |format|
format.html { redirect_to books_url, notice: 'Book was successfully destroyed.' }
format.json { head :no_content }
end
end
private
# Use callbacks to share common setup or constraints between actions.
def set_book
@book = Book.find(params[:id])
end
# Never trust parameters from the scary internet, only allow the white list through.
def book_params
params.require(:book).permit(:name, :author, :description, :category_id, :sub_category_id)
end
end
That's all
I hope this helps.
