I want to create an object from data API. At first, the user will have to enter his immaticulation number. Once registration typed him return the following data in the view show
vehicles_controller:
#vehicle = Vehicle.new
#vehicles = []
vehicle_number = params['immatricule'].capitalize
vehicles.each do |vehicule|
data_api = CarRegistrationFrance.Lookup(#{"vehicle_number"},"username","password")
Api_data response:
=> {"Description"=>"RENAULT CLIO IV", "RegistrationYear"=>"2017", "CarMake"=>{"CurrentTextValue"=>"RENAULT"}, "CarModel"=>{"CurrentTextValue"=>"CLIO IV"}, "EngineSize"=>{"CurrentTextValue"=>"4"}, "FuelType"=>{"CurrentTextValue"=>"DIESEL"}, "MakeDescription"=>{"CurrentTextValue"=>"RENAULT"}, "ModelDescription"=>{"CurrentTextValue"=>"CLIO IV"}, "Immobiliser"=>{"CurrentTextValue"=>""}, "IndicativeValue"=>{"CurrentTextValue"=>0}, "DriverSide"=>{"CurrentTextValue"=>""}, "BodyStyle"=>{"CurrentTextValue"=>"BERLINE 5 PORTES"}, "RegistrationDate"=>"2017-10-30","ExtendedData"=>{"anneeSortie"=>"2017", "boiteDeVitesse"=>"", "carburantVersion"=>"D", "carrosserieVersion"=>"", "classeSra"=>"K", "libVersion"=>"1.5 DCI 90 EDITION ONE EDC", "libelleModele"=>"CLIO IV", "marque"=>"RE", "modele"=>"88", "produit"=>"", "puissance"=>"4", "version"=>"", "cleCarrosserie"=>"", "groupeSra"=>"30", "nbPlace"=>"5", "datePremiereMiseCirculation"=>"30102017", "questionBatterie"=>"", "electrique"=>"", "genre"=>"", "typeVehicule"=>"", "numSerieMoteur"=>"VF15RBJ0D58888591", "valeurANeufSRA"=>"", "niveauRisqueVol"=>"", "protectionConstructeur"=>"", "puissanceDyn"=>"", "segmentVeh"=>""}}
#vehicles << data_api
vehicle.description => data_api["Description"]
vehicle.annee => data_api["RegistrationYear"]
def vehicle_params
params.require(:voiture).permit(:immatricule, :description, :annee)
end
Once the user enters his registration numbers I want to join
data_api ["Description"] << vehicle ["description"]
attach the data to the attribute of the vehicle object
data_api ["RegistrationYear"] << vehicle ["year"]
/user[:id]/vehicle/new its an example
<%= form_tag("/vehicle", method: "post") do %>
<%= label_tag(:immatricule, "") %>
<%= text_field_tag(:immatricule) %>
<%= submit_tag("create") %>
/user[:id]/vehicle/show it an example
<%= #vehicle.api_data["Description"] %>
<%= #vehicle.api_data["RegistrationYear"] %>
enter your immatricule number
post immatricule of vehicle user to api_data
create objet vehicle from response api_data
render show view
I've tried several operations but I can not find a solution.
So this sort of feels like you coming from a background without being CRUD (Create, Read, Update, Delete) aware ... based on your not listing the controllers etc that you are working to achieve this stuff (crucial to any response to answer your question).
Based on the status of the question 2/22 # 06:18am -600 here is some quick notes ...
You are going to want to do this walk-thru for getting started - RailsGuides.
Second, I think from your URL you listed - you have a nested route & are using a matching nested model. The answer changes which controller/action/routing I am suggesting - so make sure to clarify if you aren't before you try to understand this answer ...
All of these are guess work as there are details of your implementation we are missing (route.rb file, if this is a script you as admin are calling or each user is running the update themselves, if this stuff works at all).
Once finished the question you meant to ask should be ...
"Which controller & controller action should I use to update the registration information?" (Commonly shown as controller#action)
The CRUD answer is the update (rails calls it Edit to display view & update to execute).
The reason your question throwing people off is that the Rails Way (CRUD) already has basic code for a controller and action for that controller action to update the field. You shouldn't have to create an object yourself - all data objects that are permanent should be Rails model objects.
In your case Vehicle model in the app/models/vehicle.rb would be my guess. You might choose to nest the route for that in the config/routes.rb file as ...
Rails.application.routes.draw do
resources :users do
resources :vehicle
...
Which would give you a route/url of "/{:user_id}/{:vehicle_id}/{controller action}".
This assumes ...
A user coming to your application on the web or network
They sign up or in
Display the info from the API (I'm not sure if your are looking to feed this info back to that API & that is why you need the object - but assuming you are not)
After the user#show controller pulls vehicle model pulls the info from the API
Your controller will redirect them to the CRUD read action (Rails calls this Show). It's also already coded in the controller action for update.
In your case this would likely be ... User#show, which would have accepts_nested_attributes_for :RegistrationYear and maybe the :Description in the User model, referring to the fields in the Vehicle model you already have working.
For the other case ... you are simply wrapping another API which is getting updated and your rails application isn't holding anything ...
You need a user entity or authentication ... maybe you are getting an omni_auth or other security login token from the API you referenced ... so your steps ...
Either login in handled or you create/ login the user
Your User#Show should either have a link to the Vehicle#Update or the User#Show view should include that form with field with the user & vehicle id's ... which are filled in already as the the controller executed that API query pull all the information & have the two fields to be updated.
The submit button should in a normal rails app be a link to another controller#action which would just execute the API's update interface instead of stashing the info into your own db ... though you could easily put that API interface call in the controller#action responsible for showing the form.
I suggest you do a standard object file if you are just wrapping the API with your own rails app ...
# depending on where you put this you might need to load it yourself
app/lib/other_api_connection.rb
# rails prefers this format as part of ruby & it's class autoloading
class OtherAPI < CarRegistrationFrance
attr_accessor :registration, :description
def initialize(search_immat, user, pass, api_url = {whatever currently})
...
#user = user
#pass = pass
#record = look_up
#api_url = api_url
end
def look_up(search_immat)
...
Lookup("#{search_immat}", #user, #pass)
end
def update_api
begin
... {you haven't shown us the update API url} ...
rescue {some error from api}
return "{some error message}"
end
end
end
So ... you have the API handler object now ...
For use you call it in the controller#action ... lets say User#Show, which submit redirects to User#Update or Vehicle#Update
class Vehicle < ActionController::Base
...
def update
...
# normal stuff probably needs to be deleted if you aren't saving to your application db THEN updating API (aka just wrapping an API - which I'm assuming you are doing since you haven't said otherwise & it's less work).
# also you could pass the object as a parameter in the submit link - but that's not really CRUD per say
#user = {whatever user is}
api = OtherAPI.new(user, pass)
# you might have to permit this as parameter to pull it out
#response_code = api.update_api(:RegistrationYear, :Description) # or whole vehicle record if the API requires
if #response_code == {whatever valid code is from that API documentation}
format.html { redirect_to #vehicle, notice: 'Vehicle was successfully updated.' }
else
format.html { render :edit }
format.json { render json: #vehicle.errors, status: :unprocessable_entity }
end
... rest of controller actions
end
Note - I suggested making an API interface class/object because you can then call the code from either controller or action & only have to make the changes in one place if the api url is changed etc ... but you might have to include OtherAPI at the top of each controller code.
hello Thanks for your help

"date_circulation" == data_api["RegistrationDate"]
"fuel_type" == data_api["fuel_type"]
end
I'm looking for how to do that in my controller users or vehicles
I'm having some troubles with a project I'm working on. Be warned I consider myself very much a beginner/novice at all this still :)
To keep things short and sweet, I'm using Rails & active admin to build up an admin interface where i can perform CRUD operations on my database models, which is all working great. However I recently decided I wanted to add another field to one of my models, a "description" field, so generated a migration, ran rake db:migrate and updated my list of allowed params in my controller & active admin resource.
My problem is data is not saved for this new "description" field - wether its via creating a new entry or updating an existing one. I can see the output in the terminal confirms it is being filtered out by strong params; returning Unpermitted parameter: :Description However i am under the impression i have set up my strong params correctly, so I'm unsure if i have set up my permit params properly or what else i can do.
Using Rails 5.1.0 & will post code below.
class CellsController < InheritedResources::Base
def index
end
private
def cell_params
params.require(:cell).permit(:name, :description)
end
end
#database schema for my cell model
create_table "cells", force: :cascade do |t|
t.string "name"
t.datetime "created_at", null: false
t.datetime "updated_at", null: false
t.text "Description"
end
#Active Admin resource
ActiveAdmin.register Cell do
permit_params :name, :description
end
Again, greatly appreciate any help as I'm sure I've overlooked something, happy to provide any other information that is required :)
Thankyou!
To me it looks like the description param is not accepted because the model only has a Description column (with a capitalised D). To fix that, either change each params.permit(:description) to params.permit(:Description) or just rename the column inside a new migration:
def change
rename_column :cells, :Description, :description
end
I recommend renaming the column as it will avoid any trouble with the column in the future.
How do I add data to a table in Rails?
So far I have created a Rails app that pulls in data from an API. Next, I have ran the command
rails generate model order
and I have /db/migrate/timestamp_create_orders.rb
class CreateOrders < ActiveRecord::Migration
def change
create_table :orders do |t|
t.string :email, null: false
t.string :order_date, null: false
t.string :total_price, null: false
t.string :order_number, null: false
t.string :cust_name, null: false
t.string :zip_code, null: false
t.timestamps null: false
end
end
end
Next, I believe I need to run db:migrate and that will create the table.
My question is, how do I add data to this table? I want the user to visit the app, it pulls in the data, and stores it in this table.
I have found conflicting advice..
Should I just use the advice from here
Order.create(:email=>'fake#fake.com',:order_data=>"...
But other advise seems to say not to do this here and here. Though they are all pretty old
You do not create database entries in migrations, you usually create schema or specify changes in the schema in migration files. You use seeds for creating seed data in the database.
To create new data in database through rails you can use either create or new method but you need to save the data as mentioned in other posts in your links when you are using new method.
While creating or migrating a new database table, table row is not automatically added. You need to add them manually. One way to populate the newly created database table is using seeds.rb file which is located in your application db folder. You can add Faker gem to your application for creating fake table attribute elements. An example using faker:
(1..3).each do # it'll create 3 new order
Order.create(email: Faker::Internet.email, order_date: Faker::Date.between(2.days.ago, Date.today))
end
Then run rake db:seed in your project folder console.
If you have some validation in your order.rb file, then you can create new instance of that order and then save it like:
order = Order.new(....)
order.save(validate: false)
Using Rails Admin with Dragonfly. However when I have created a new post with an attachment connected :ob to dragonfly and wants to edit it. It sais "No file chosen". As it doesn't pick up that there is already a file present?
In my rails_admin I have done this.
edit do
field :name
field :information
field :ob, :dragonfly
field :document_categories
end
Here's my model:
class Document < ActiveRecord::Base
has_and_belongs_to_many :document_categories
after_commit :generate_versions, on: :create
dragonfly_accessor :ob
validates :name, :ob, presence: true
def generate_versions
DocumentWorker.perform_async(self.id)
end
def convertable_image?
unless self.try(:ob).nil?
self.try(:ob).mime_type.include?("image") || self.try(:ob).mime_type.include?("pdf")
else
return false
end
end
def respond_with_type
case self.try(:ob).mime_type.split("/")[1]
when "vnd.ms-powerpoint" , "vnd.openxmlformats-officedocument.presentationml.presentation", "application/vnd.openxmlformats-officedocument.presentationml.template"
"powerpoint"
when "application/vnd.ms-excel" , "vnd.openxmlformats-officedocument.spreadsheetml.sheet"
"excel"
when "application/msword" , "vnd.openxmlformats-officedocument.wordprocessingml.document"
"word"
else
self.try(:ob).mime_type.split("/")[1]
end
end
default_scope{order("name ASC")}
end
Here's my schema:
create_table "documents", force: :cascade do |t|
t.string "name"
t.string "ob"
t.datetime "created_at", null: false
t.datetime "updated_at", null: false
t.string "ob_uid"
t.string "ob_name"
t.text "information"
end
Is there anything else that I need to do in order for it to pick up the file?

I managed to reproduce your issue using the configuration you provided and the fix that worked for me turned out to be incredibly simple: just remove the ob column from the documents table.
Explanation: by default, Dragonfly stores the attached documents on disk (in a file store) to the directory specified in the Dragonfly initializer. In the database, Dragonfly stores only the name and UID of the documents. In your case it's the ob_uid and ob_name columns that you correctly added to your schema.
So, unless you configured some custom store for the documents, I assume you use the default file store and the ob column is not needed. In fact, it confuses the rails_admin's dragonfly support code in such a way that, indeed, the edit page incorrectly show "No file chosen" all the time.
Adding an image after the fix (for simplicity, I removed the document_categories association from both the model and the edit action in rails_admin):
I'm just figuring out my way around rails but I need a little help with the rails generate scaffold command.
Here's the command that I'd like to use
rails generate scaffold Expense user:??? name:string description:text
I'd like the description field to be nullable and the users field to be linked to another Model — in this case I'd like to create a foreign key to the Users. I'm using the devise authentication framework.
I've read that many RoR developers try and avoid the scaffolding method and opt for the manual approach instead but my web-app is quite simple and I've thought of going the scaffolding way.
Scaffolding only generates the migration that you then run. Once the file is generated simply crack open the generated migration and adjust any of the values you need specific constraints on. By default columns are set to null unless you specify otherwise e.g.:
create_table "slugs", :force => true do |t|
t.integer "sequence", :default => 1, :null => false
t.string "sluggable_type", :limit => 40
t.string "scope", :limit => 40
t.datetime "created_at"
end
This is the code generated by the friendly_id plugin as you can see they have specified that the sequence column cannot be null while the other fields have other constraints.
