我想从数据API创建一个对象。首先，用户必须输入他的immaticulation数字。一旦注册输入，他将在视图中返回以下数据
@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
一旦用户输入他想要加入的注册号码
data_api ["Description"] << vehicle ["description"]
将数据附加到车辆对象的属性
data_api ["RegistrationYear"] << vehicle ["year"]
/ user [：id] / vehicle / new是一个例子
<%= form_tag("/vehicle", method: "post") do %>
<%= label_tag(:immatricule, "") %>
<%= text_field_tag(:immatricule) %>
<%= submit_tag("create") %>
/ user [：id] / vehicle /显示一个例子
<%= @vehicle.api_data["Description"] %>
<%= @vehicle.api_data["RegistrationYear"] %>
我已经尝试了几次操作，但我找不到解决方案。
所以这种感觉就像你来自背景而不是CRUD（Create, Read, Update, Delete）意识到......基于你没有列出你正在努力实现这些东西的控制器等（对回答你的问题的任何回应至关重要）。
基于问题2/22 @ 06:18 am -600的状态，这里有一些快速说明......
你想要开始这个步骤 - RailsGuides。
其次，我认为你列出的URL - 你有一个嵌套的路由，并使用匹配的嵌套模型。答案改变了我建议的控制器/动作/路由 - 所以在你试图理解这个答案之前一定要弄清楚你是不是......
所有这些都是猜测工作，因为我们缺少您的实现的详细信息（route.rb文件，如果这是您作为管理员正在调用的脚本或每个用户自己运行更新，如果这些东西都适用）。
一旦完成你要问的问题应该是......
“我应该使用哪种控制器和控制器操作来更新注册信息？” （通常显示为controller#action）
CRUD的答案是update（rails称它为Edit来显示视图和update来执行）。
你抛出问题的原因是Rails Way（CRUD）已经拥有控制器的基本代码和该控制器动作更新字段的动作。您不必自己创建对象 - 所有永久性的数据对象都应该是Rails模型对象。
在你的情况下，Vehicle中的app/models/vehicle.rb模型将是我的猜测。您可以选择在config/routes.rb文件中为此路由嵌套为...
Rails.application.routes.draw do
resources :users do
resources :vehicle
...
哪个会给你一个"/{:user_id}/{:vehicle_id}/{controller action}"的路线/网址。
这假设......
read动作（Rails称之为Show）。它也已经在控制器动作中编码以进行更新。在你的情况下，这可能是... User#show，它将有accepts_nested_attributes_for :RegistrationYear和:Description模型中的User，指的是你已经工作的Vehicle模型中的字段。
对于另一种情况......你只是包装另一个API，它正在更新，你的rails应用程序没有任何东西......
您需要一个用户实体或身份验证...也许您从您引用的API中获取omni_auth或其他安全登录令牌...所以您的步骤......
User#Show应该有一个指向Vehicle#Update的链接，或者User#Show视图应该包含带有用户和车辆ID的字段的表单...已经填写，因为控制器执行API查询提取所有信息并且有两个要更新的字段。controller#action负责用于显示表格。如果您只是使用自己的rails应用程序包装API，我建议您执行标准对象文件...
# 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
那么......你现在有了API处理程序对象......
使用时你可以在控制器#action中调用它...让我们说用户＃显示，提交重定向到User#Update或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
注意 - 我建议创建一个API接口类/对象，因为您可以从控制器或操作中调用代码，只需要在一个地方进行更改，如果更改了api url等等...但是你可能需要在include OtherAPI处每个控制器代码的顶部。
你好，谢谢你的帮助
我使用设备来验证用户
create_table "users", force: :cascade do |t|

has_many :vehicles

end
我需要这条路线：
user_vehicles GET /users/:user_id/vehicles(.:format) vehicles#index
POST /users/:user_id/vehicles(.:format) vehicles#create
new_user_vehicle GET /users/:user_id/vehicles/new(.:format) vehicles#new
edit_user_vehicle GET /users/:user_id/vehicles/:id/edit(.:format) vehicles#edit
user_vehicle GET /users/:user_id/vehicles/:id(.:format) vehicles#show
PATCH /users/:user_id/vehicles/:id(.:format) vehicles#update
PUT /users/:user_id/vehicles/:id(.:format) vehicles#update
DELETE /users/:user_id/vehicles/:id(.:format) vehicles#destroy
但我正在使用设计
在我的控制器中我需要构建具有响应的车辆api我需要在数据库中保存数据从数字immatricule形式新车辆用户输入number_immatricule“immatricule”=形成新车辆[：immatricule]用户表格获取data_api
def build_vehicle_user_from_api_data
"description" == data_api["description"]
"marque" == data_api["CarMake"]
"date_circulation" == data_api["RegistrationDate"]
"fuel_type" == data_api["fuel_type"]
end
我正在寻找如何在我的控制器用户或车辆中做到这一点
