Rails: def create does not add data to table using Rest - ruby-on-rails

Question

I want to add data to table through rest api with url: localhost:3000/api/v1/shoppinglists#create?grocery=fruits
I have created a model already, my controller is located under api/v1/shoppinglists_controller.rb and the code for that is:
shoppinglists_controller.rb:
module Api
module V1
class ShoppinglistsController < ApplicationController
def index
shop = Shoppinglist.all
render json: shop.to_json
end
def create
#tst = Shoppinglist.create(grocery: params[:grocery])
end
end
end
end
routes.rb:
Rails.application.routes.draw do
namespace :api do
namespace :v1 do
get '/shoppinglists' => 'shoppinglists#index'
post '/shoppinglists' => 'shoppinglists#create'
end
end
end
Model-migration: shoppinglist.rb:
class CreateShoppinglists < ActiveRecord::Migration
def change
create_table :shoppinglists do |t|
t.integer :shopid
t.string :type
t.string :grocery
t.string :status
t.timestamps null: false
end
end
end
By default, def index gets triggered but when I do: localhost:3000/api/v1/shoppinglist#create?grocery=fruits then I check on commandline, I still see:
Started GET "/api/v1/shoppinglists" for ::1 at 2015-06-23 23:59:06 -0400
Processing by Api::V1::ShoppinglistsController#index as HTML
Shoppinglist Load (0.3ms) SELECT "shoppinglists".* FROM "shoppinglists"
Completed 200 OK in 44ms (Views: 0.2ms | ActiveRecord: 0.4ms)
and my table is empty. There are 2 problems:
I dont understand why still index is getting triggered and how can I make def create to actually insert value in grocery column through rest api.
[Solved] I used a client called Postman to solve this problem but still facing problem (2) as all null values are entered in my table and not the one being entered through url. My command line logs now say [logs]
Once it gets triggered then is my code right for "create" def?
[Solved] Issue was with the way I was sending values through post. I had to add values to form-data tab (key,val) in Postman instead of through url for it to work

Create action requires a POST request and when you visit localhost:3000/api/v1/shoppinglist#create?grocery=fruits in a browser, it sends a GET request instead of a POST request, treating it as a URI and hence triggering index action. To send a POST request you can use CURL command in terminal or httparty
curl -H 'Content-Type: application/json'-H 'Accept: application/json' -X POST http://localhost:3000/api/v1/shoppinglists -d {"grocery": "fruits"}
where -H refers to the headers set in request and -X is for changing default GET verb and -d is for the data that you want to send. For details refer to curl
