I am using Postman to make a Post request to my Rails backend and the new entry is created successfully with all values being 'nil'.
I can see that the parameters are being passed into the request as expected but I cannot figure out why they aren't making it into the new entry.
My controller:
class PinsController < ApplicationController
def index
pins = Pin.all
render json: pins, status: :ok
end
def create
# pin = Pin.create!(pin_params)
pin = Pin.create(username: params[:username], title: params[:title], desc: params[:desc], rating: params[:rating], lat: params[:lat], long: params[:long])
render json: pin, status: :created
end
private
def pin_params
params.permit(:username, :title, :desc, :rating, :lat, :long)
end
end
The output of the rails server:

#customer.save
redirect_to "https://www.shoptet.cz/", allow_other_host: true

Thanks for help, problem fixed by disabling turbo on the button:

I am uploading legacy articles to my Rails app. I am sending created_at as a parameter in my request as recommended in this answer. However, this attribute seemingly is not passed "through". I can puts(params[:created_at]) and see my custom created_at, yet in the logs the article is INSERTed with a created_at of the current timestamp.
Here is my articles controller:
class ArticlesController < ApplicationController
before_action :set_article, only: [:show, :update, :destroy]
...
# POST /articles
def create
#section = Section.friendly.find(params[:section_id])
# Can't let people publish by default
#article = #section.articles.build(
article_params.merge(is_published: false)
)
if #article.save
render json: #article, status: :created, location: #article
else
render json: #article.errors, status: :unprocessable_entity
end
end
end
My request is:
http POST :3000/articles title='example' section_id=1 content="<p>the section exists.</p>" slug="example" created_at="2017-06-109T17:57:55.149-05:00"

In my schema.rb:

My model has no extra methods/callbacks that would ruin the request. It only contains relationships. I don't know if this is relevant, but I saw it in a GitHub issue somewhere: articles and users are in a many2many with an authorships model, and I use devise to authenticate users.
In conclusion, the app is receiving the created_at param just fine, but it is overridden with the default timestamp. If I set record_timestamps to false, the created_at just becomes nil.
Why is my created_at just seemingly ignored?
Rails 5.1, Ruby 2.4.2, Postgres 10.1
Answer given by max: there was a syntatical error in my timestamp. It was not valid, and was ignored by Rails.
I have looked at previous SO solutions on accepts_nested_attributes here and here, but I am still getting the error. I am using React as front end and Rails back end. I am trying to create a request to be sent to schedules, and from there to populate to workers.
I am using Rails 5.0.2. I have a schedule, worker, roster models.
//Schedule
has_many :workers, through: :rosters, dependent: :destroy
has_many :rosters
accepts_nested_attributes_for :workers #implement accept_nested_attributes here
//Roster
belongs_to :schedule
belongs_to :worker
//Worker
has_many :schedules, through: :rosters
has_many :rosters
And here is my Schedule controller:
def create
#schedule = Schedule.new(schedule_params)
if #schedule.save
render json: #schedule
else
render json: #schedule, status: :unprocessable_entity
end
end
...
private
def schedule_params
params.permit(:date, :user_id, :workers_attributes => [:worker_id, :name, :phone])
end
Here is the error that I got:
app/controllers/schedules_controller.rb:13:in `create'

Unpermitted parameter: schedule
Completed 500 Internal Server Error in 15ms (ActiveRecord: 0.0ms)
TypeError (no implicit conversion of Symbol into Integer):
app/controllers/schedules_controller.rb:13:in `create'
Why is my request shows Unpermitted parameter schedule? If I remove workers_attributes and only have params.permit(:date, :user_id), it works. I can't figure out why the error points to schedule. How can I make successful POST nested_attributes request to rails?
I am using fetch to do POST request from react side:
...
return fetch(`api/schedules`, {
method: 'POST',
headers: {
'Content-Type': 'application/json',
},
body: JSON.stringify({
date: date,
user_id: 1,
workers_attributes: {name: "Iggy Test", phone: "123-456-7890"}
})
EDIT:
After following answer from #gabrielhilal, I added require(): params.require(:schedule).permit(:date, :user_id, :workers_attributes => [:id, :name, :phone]), and edited the fetch POST on React's end to have array of objects instead of plain objects: workers_attributes: [{name: "Iggy Test", phone: "123-456-7890"}]. It does not complain anymore, and it does register new schedule. However, new workers are all nil:
#Worker.last shows:
#<Worker id: 32, name: nil, phone: nil, created_at: "2017-05-23 19:36:09", updated_at: "2017-05-23 19:36:09">
Sorry, don't mean to create nested question, but does anyone know why it is nil?
EDIT 2:
I got it to work, sort of.
If I have
def create
#schedule = Schedule.new(schedule_params)
#workers = #schedule.rosters.build.build_worker
...
and
//schedule_params
params.permit(:date, :user_id, :workers_attributes => [:id, :name, :pho
ne])
I was able to have "Iggy Test" to display, but it immediately creates another nil worker.

Your post:
{
"date"=>"2017-05-25T02:00:00.000Z",
"user_id"=>1,
"workers_attributes"=>{
"name"=>"Iggy Test",
"phone"=>"123-456-7890"
},
"schedule"=> {
"date"=>"2017-05-25T02:00:00.000Z",
"user_id"=>1
}
}
You have two issues:
schedule is not permitted (that's why you see the message in the logs), but it will be just ignored anyway (won't raise any error).
the workers_attributes should be a collection of workers and not a simple hash, so that's why you are having the error.
You should get something like the following in the post request:
{
"date"=>"2017-05-25T02:00:00.000Z",
"user_id"=>1,
"workers_attributes"=>{
"0" => {
"name"=>"Iggy Test",
"phone"=>"123-456-7890"
}
}
}
I have a problem with nested attributes. Creating works but when I update, the error message shows me that the values in the relation are not set. I can't find the reason.
The main model
class Product < ActiveRecord::Base
has_many :product_options
accepts_nested_attributes_for :product_options,
:allow_destroy => true,
:reject_if => proc { | r | r["name"].blank? or r["value"].blank? }
end
The nested model
class ProductOption < ActiveRecord::Base
belongs_to :product
validates :name, :presence => true
validates :value, :presence => true
end
The controller is a bit shorted.
Items is a model where Product is related to as has_one
class Admin::ProductsController < Admin::ApplicationController
before_action :set_product, only: [ :new, :show, :edit, :update, :destroy ]
def create
#product = Product.new( product_params )

if #product.save
#product.product_options.build
format.js { render :js => "alert( 'Daten gespeichert!' );" }
else

end
end
end
def update

else

end
end
end
private
# UPDATE: creating the product_options at this time
# produces the described error :)
def set_product
#item = Item.find_by_id( params[ :item_id ] ) if params[ :item_id ]
#product = #item.product ? #item.product : #item.build_product
# WRONG Place for generating new options
# 2.times { #product.product_options.build }
end
def product_params
params.require( :product ).permit( :item_id, :name, :title, :active, :product_options_attributes => [ :id, :name, :value, :_destroy ] )
end
end
The console output for the create is working and looks like

I think I know what is the problem with your code. The accepts_nested_attributes_for does not require you to build any of the associated models. If the appropriate params are passed in then the model automatically builds or updates the associations.
In your case in the update method what you do is the following:
You find the relevant product. So far so good (although you could actually use a specific product id in your form)
Then you build two product options (in #set_product). This is the problem.
And in the end you update the model based on the parameters.
Now the problem with the second step is that you basically build two empty associated instances. Those are not affected by the accepts_nested_attributes. As a result you are trying to save 2+2 product options (the ones you build and the ones created by the params). Obviously you get the validation error due to the fact the two of the models have no attributes set.
You can make sure my hypothesis is correct by removing the validators from ProductOption. On update you should get 4 associated product options persisted.

route is
get '/:title', to: 'guidelines#show', as: :seeguideline
Are you sure your route is passing the :title param? What does your console log show for the SQL request for the query? I have a feeling your route isn't passing what you think it's passing...
Also, you're going to want to handle the case that the query comes back empty anyway. Having the app blow up probably isn't what you want.
