Building a JSON API in Rails 4 - iphone

Question

How to build the JSON API for add the post. I am creating the Rails application and connect it with iphone application by using the JSON API. User can add the Blog/Post from application so how I can add the blog data like title, text and image in rails database(using the new method).

Answer 1

You can have your controllers return JSON by doing something like:
class ProjectsController < ApplicationController
def index
respond_to do |format|
format.json { render json: Project.all }
end
end
def show
respond_to do |format|
format.json { render json: Project.where(name: params[:name])}
end
end
end
This is essentially turning rails into a JSON API. Make sure to add your model attributes to the Active::Model::serializers
class ProjectSerializer < ApplicationSerializer
attributes :id, :name, :description, :imgUrl, :deployUrl
end

Answer 2

class ApiController < ApplicationController
respond_to :json
def patient
#patients = Patient.all
respond_with(#patients)
end
def disease
#diseasecode = Diseasecode.all
respond_with(#diseasecode)
end
def addpatient
#patient = Patient.new(params[:id])
flash[:notice] = 'Patient was successfully created.' if #patient.save
respond_with(#patient)
end
def patient_params
params.require(:patient).permit(:name, :gender, :date_of_birth, :contact_no, :billing_id, :physician)
end
end
I am getting still problem def addpatient method is never add the post if I hit the url www.localhost:3000/api/addpatient.json?name=test&gender=male&date_of_birth=10/02/2010&contact_no=58475896&billing_id=25&physician=48
