I'm rendering json without object title. So I tried to render it as text as follows
render :text=>
[{
"id": "0",
"heading": "Trending this Week",
"title": "Prost Brew Pub",
"place": "Sholinganallur",
"image": "http://192.168.0.103/test2/blur.jpg",
"rating": 4.3,
"amount": "Rs. 1800 for two people",
"review": "320 Reviews",
"photos": "630 Photos",
"genre": ["British", "Mexican", "Continental"]
},...
It convert the above as following
[{:id=>"0", :heading=>"Trending this Week", :title=>"Prost Brew Pub", :place=>"Sholinganallur", :image=>"http://192.168.0.103/test2/blur.jpg", :rating=>4.3, :amount=>"Rs. 1800 for two people", :review=>"320 Reviews", :photos=>"630 Photos", :genre=>["British", "Mexican", "Continental"]}
why did it convert the "id": "0" to :id=>"0" ?
How can I render the above array without any change? thanks in advance.
Is there and render method available to get the object without it's title?
Your ":text" is an array is of Hashes. So Ruby is rendering it in Hash syntax. If you want json you should render json not text.
render json: #object, status: :ok

I am facing a situation where it seems helpful to have a gem that can format the JSON that comes as a response from any API. For example I may make a call to fetch some data but I don't need all the fields, instead I need to create a new JSON by parsing the original one to only include some fields and also be able to select only some of nested fields from arrays or array of arrays inside that JSON. The result of the reduced JSON can be a JSON that has only one level of nesting.
Can you please help me if there is an existing gem in Ruby to do this?
I am showing an example to explain better my situation.
Original JSON:
[{
"key1": "test",
"key2": "Test",
"key3": "Test",
"key4": [
"key1": "test"
],
"key5": [
"key6": "test",
"key7": [
{"key8": ["test", "test"]},
{"key8": ["test2", "test3"]}
]
]
}]
And after executing some function, for example:
select(["key1", "key2", "key5.key6.key7.key8"])
The result would be:
[{
"key1": "test",
"key2": "Test",
"key8": [
"test", "test", "test2", "test3"
]
}]
I'm having problems importing a .json file and saving the data inside it in the api database. My code is like this:
def create
content = JSON.parse(File.open(params[:products]).read)
#product = Product.new(content)
if #product.save
render json: { message: 'Produto Salvo', data: #product }, status: 200
else
render json: #product.errors, status: :unprocessable_entity
end
end
The file(products.json)contains this data:
[{
"title": "Brown eggs",
"type": "dairy",
"description": "Raw organic brown eggs in a basket",
"filename": "0.jpg",
"height": 600,
"width": 400,
"price": 28.1,
"rating": 4
}, {
"title": "Sweet fresh stawberry",
"type": "fruit",
"description": "Sweet fresh stawberry on the wooden table",
"filename": "1.jpg",
"height": 450,
"width": 299,
"price": 29.45,
"rating": 4
}]
By the time I implement the method, all fields are saved as NIL:
#<ActiveRecord::Relation [#<Product id: 3, title: nil, product_type: nil, description: nil, filename: nil, height: nil, width: nil, price: nil, rating: nil, created_at: "2021-11-10 14:15:11.261454000 +0000", updated_at: "2021-11-10 14:15:11.261454000 +0000">]>
How do I save with the data correctly filled in?
It looks like you're reading in an array of multiple products?
I would suggest inserting a binding.pry between where you set content and where you set #product
Paste the value of content here and I think the solution will become clear.
I am using 'active_model_serializers', '~> 0.10.6' for rendering my API response. For my index action I am doing this -
render json: #items, root: 'data', each_serializer: ItemsSerializer
but in my response, I am not getting the root key - data
[
{
"id": 85,
"title": "B",
"source": "manager_added",
"shared": true,
"status": "suggested",
"item_type": "action_item",
"manager": {
"id": 2614,
"full_name": "Calvin H",
"first_name": "Calvin"
},
"reportee": {
"id": 2614,
"full_name": "Calvin H",
"first_name": "Calvin"
}
},
{
"id": 87,
"title": "D",
"source": "manager_added",
"shared": true,
"status": "suggested",
"item_type": "action_item",
"manager": {
"id": 2614,
"full_name": "Calvin H",
"first_name": "Calvin"
},
"reportee": {
"id": 2614,
"full_name": "Calvin H",
"first_name": "Calvin"
}
}
]
What I am doing wrong here?
The hardest part with AMS is finding it's right documentation. Based on the version you have mentioned, here's the documentation link:
https://github.com/rails-api/active_model_serializers/tree/0-10-stable/docs
There are 3 adapters:
:default (There won't be any root, basically root key is useless, even if you add it)
:json (This is what you need, you can add custom root key. https://github.com/rails-api/active_model_serializers/blob/0-10-stable/docs/general/adapters.md#example-output-1)
:json_api (Default root key will be data, but you can customize, maybe you can use this, but it will change the whole structure of your response json into something like: https://github.com/rails-api/active_model_serializers/blob/0-10-stable/docs/general/adapters.md#example-output-2)
Answer:
render json: #items, root: 'data', adapter: :json, each_serializer: ItemsSerializer
or
render json: #items, adapter: :json, each_serializer: ItemsSerializer
Here it's my products.controller
def index
if params[:page]
#product = Product.page(params[:page]).per(5)
else
#product = Product.order('updated_at DESC')
end
render json: {
status: '200',
message: 'OK',
data: ActiveModel::Serializer::CollectionSerializer.new(#product, each_serializer: ProductSerializer)},status: 200
end
def show
render json: {
status: '200',
message: 'OK',
data: ActiveModel::Serializer::CollectionSerializer.new(#product, each_serializer: ProductSerializer)},status: 200
end
Here my product serializer
class ProductSerializer < AplicationSerializer
attributes :id, :product_name, :category, :company, :description, :logo_img, :web_link
belongs_to :category
has_many :images

If I try to access localhost:3000/products/, it can display all the data that I want, but if I want to try localhost:3000/products/1, it's wrong, so what the wrong about my code?
{
"status": "200",
"message": "OK",
"data": [
{
"id": 1,
"product_name": "MDS",
"category": {
"id": 4,
"category": "Market Place",
"created_at": "2018-04-12T02:58:59.949Z",
"updated_at": "2018-04-12T02:58:59.949Z"
},
"company": "PT Media Data ",
"description": "ISP di Indo",
"logo_img": "mds.jpg",
"web_link": "https://mds.co/",",
"images": [
{
"id": 1,
"link": "http:/mds.com/mds.png"
},
{
"id": 2,
"link": "http:/mds.com/mds.png"
},
{
"id": 3,
"link": "http:/mds.com/mds.png"
},
{
"id": 4,
"link": "http:/mds.com/mds.png"
}
]
}
]
}
in the above is the display I want to display at http://localhost:3000/products/1, but i still got no appear, even though i can display it with same code on def index
Thanks for your help
The only thing that can seem to be missing here is setting the #product
If you have a before_action :show, :set_product this might not be the problem.
The other difference is between an array in the index and a single element in the show. you better use ProductSerializer.new(#product).as_json instead of using the collection serializer
iam using active model serializers in my rails, this is my snippet
# GET /users
def index
#users = User.all
render json: {data: #users, status: httpstatus[:getSuccess]}
# render json: {data: #users, status: httpstatus[:getSuccess]}
end
but its showing like this in postman
"data": [
{
"id": 38,
"name": "tyasa",
"age": 21,
"created_at": "2017-05-30T06:23:03.504Z",
"updated_at": "2017-05-30T06:23:03.504Z"
},
{
"id": 39,
"name": "wahyu",
"age": 21,
"created_at": "2017-05-30T06:23:37.359Z",
"updated_at": "2017-05-30T06:23:37.359Z"
},]
but its work when just render the #users
# GET /users
def index
#users = User.all
render json: {data: #users, status: httpstatus[:getSuccess]}
# render json: #users
end
i just wanna delete created at and update at from the json.
How to solve this..
sory bad english
I just wanna delete created at and update at from the json.
You can use except option of as_json
render json: {data: #users.as_json(:except => [:created_at, :updated_at]), status: httpstatus[:getSuccess]}
which should give you
"data": [
{
"id": 38,
"name": "tyasa",
"age": 21
},
{
"id": 39,
"name": "wahyu",
"age": 21
},]
