api saving multiple children records only save one with missing fields ruby

Question

Making an api call that has on it a parent record (which is item) and children records (which are photos) the item record get saved fine, but the images it only save one image with missing fields.

Here is the json im sending

{"item_category": "Books & Magazines", "item_condition": "Used",
"item_name": "Crushing it", "summary": "super awesome",
"price": 20, "active": true,"instant": 1,
"access_token": "p8Z-yZ1wRooBLsZj4yeS",
"photo_attributes":
[{"created_at": "2019-05-16 05:28:16.696408",
"image_file_name": "images.jpg",
"image_content_type": "image/jpeg","image_file_size": 257908,
"image_updated_at":"2019-05-21 15:20:55.390445"},
{"created_at": "2019-05-16 05:28:16.696408",
"image_file_name": "images.jpg",
"image_content_type": "image/jpeg","image_file_size": 257908,
"image_updated_at":"2019-05-21 15:20:55.390445"}
]}

this is the api im calling

http://localhost:3000/api/v1/createitem

here is image of the command line

as you see here the item got saved

as you see here it only took one image with 3 fields

this items.contoller.rb

 class Api::V1::ItemsController < ApplicationController
 def createitem
   @item = current_user.items.new(item_params)
   if @item.save 
     render json: @item, status: :ok
   else
     render json: { error: "Something went wrong", is_success: false}, status: 422
   end
 end
 def item_params
       params.require(:item).permit(:item_category, :item_condition,:item_name,:summary,:address,:price,:active, :instant, photo_attributes:[:created_at, :image_file_size, :image_updated_at, :image_file_name, :image_content_type])
  end
 end

this is the item.rb model

class Item < ApplicationRecord
enum instant: {Request: 0, Instant: 1}

belongs_to :user
has_many :photos
accepts_nested_attributes_for :photos

validates :item_category, presence: true
validates :item_condition, presence: true
end

I tired this solution but still did not save any photo Rails 4 nested attributes not saving

here is the update items.controller.rb

class Api::V1::ItemsController < ApplicationController
 def createitem
   @item = current_user.items.build(item_params)
   @item.photos.each do |photo|
     photo.build
   end
   if @item.save 
     render json: @item, status: :ok
   else
     render json: { error: "Something went wrong", is_success: false}, status: 422
   end
 end
 def item_params
   params.require(:item).permit(:item_category, :item_condition,:item_name,:summary,:address,:price,:active, :instant, photos_attributes:[:created_at, :image_file_size, :image_updated_at, :image_file_name, :image_content_type])
  end
 end

First your json should be

{"item_category": "Books & Magazines", "item_condition": "Used",
"item_name": "Crushing it", "summary": "super awesome",
"price": 20, "active": true,"instant": 1,
"access_token": "p8Z-yZ1wRooBLsZj4yeS",
"photo_attributes":
[{"created_at": "2019-05-16 05:28:16.696408",
"image_file_name": "images.jpg",
"image_content_type": "image/jpeg","image_file_size": 257908,
"image_updated_at":"2019-05-21 15:20:55.390445"},
{"created_at": "2019-05-16 05:28:16.696408",
"image_file_name": "images.jpg",
"image_content_type": "image/jpeg","image_file_size": 257908,
"image_updated_at":"2019-05-21 15:20:55.390445"}
]}

and second update the

def item_params
   params.require(:item).permit(:item_category, :item_condition,:item_name,:summary,:address,:price,:active, :instant, photos_attributes:[:created_at, :image_file_size, :image_updated_at, :image_file_name, :image_content_type])
end

with

def item_params
   params.require(:item).permit(:item_category, :item_condition,:item_name,:summary,:address,:price,:active, :instant, photo_attributes:[:created_at, :image_file_size, :image_updated_at, :image_file_name, :image_content_type])

end

and create method with

def create
 @item = current_user.items.new(item_params)
   if @item.save 
     render json: @item, status: :ok
   else
     render json: { error: "Something went wrong", is_success: false}, status: 422
   end
 end

I updated items.controller.rb of u told me but it still does not save any photo record and it does not throw any error, I updated the question to of what u gave me — Amer Bearat, Jun 22 '19 at 13:58
Did you updated the json also to `photo_attributes` instead of `photos_attributes` — Kamal Pandey, Jun 23 '19 at 06:11

changing the item_parms def fixed the issue

def item_params
 params[:item][:photos_attributes] = params[:photos_attributes]
 params.require(:item).permit(:item_category, :item_condition,:item_name,:summary,:address,:price,:active, :instant, photos_attributes:[:image_file_size, :image_updated_at, :image_file_name, :image_content_type])
end
