How do you know what app he's using now?

There is a system, including a number of applications that communicate with each other on REST. Let's say two applications use one hem. One of them sends REST a request that triggers the work of the hem, because we cause the rout described by the hem. How is it most important to identify the gem app we're addressing?

Inside controllers are available to the helper main_app♪ Through this chopper, it's possible to contact the choppers of the main application. Engine(I understood that your gem is a built-in app, Engine)
For each application, it's possible to identify a unique key, put it in the configuration, and write a helper that returns it. And that helper should be treated from your hip. Enginee.g.: main_app.helper_with_app_key

You don't have to change the collections. You need to use the right thing when you get out. helper and partial♪ Creating. partial (_item.html.erb) for the removal of one element and use approximately one such element helper:<%= number_to_currency(item.unit_price / 100.0) %> And mostly view <%= render @items %> The best option would be gem. https://github.com/drapergem/draper or https://github.com/rf-/keynote

Let's introduce it in a simple order!HerokuI'm sorry to get out of the airp suddenly, https://jp.heroku.com/ can be used. GitLink It's not! ) Send Build Docker images It is a service that builds the source code on the Heroku Docker container (or sends the image directly) and launches it as a server application. After you did a potty in git push heroku main You can send the source code to your account, and the deployment is complete. If you're working with GitHub git push origin main Comment It seems useful and I use it later.3. Google App EngineIt's a good thing of the airp https://cloud.google.com/appengine/ can be similar. This is a service that lets you move the Go binary on the cloud cluster that Google has. Here is the difference between Heroku, it seems to be a difference that runs the binary directly. It’s easy to use.In this way, you need to use some CI/CD services (Co。ous Integration/Co。ousmentment) because it does not work with GitHub. You can choose your favorite one because there are many things, but if you don’t have a particular stick, GitHub Actions is recommended. Google App Engine https://qiita.com/umireon/items/a831fccb96690b001292 3. CI/CD + Serverless Framework + CI daPlease feel free to contact us. This combination is also effective if the server is not always working, and you can check the response only when the request comes. The configuration file is very simple and very "Serverless"! https://www.serverless.com/blog/framework-example-golang-lambda-support CI/CDHowever, there is such a。 because you have to write an application in a format that has been determined that this method.4. CI/CD + ECSIt is finally full-fledged. EC ECS is a service that runs the Docker container on the cloud like Heroku. What’s amazing is that it can be finer, such as autoscaling by load or increasing instances. You can move different types of applications and communicate with them. Instead, you have to build Docker images yourself, and you don’t have GitHub integration. If you are not familiar with , it is difficult to set.5. CI/CD+KurbernetesThis is the final weapon. You don’t have to do it here. If you do it, it will cost 20,000 yen (monthly) I’m doing my own website. Kubernetes itself is the name of a system that executes multiple virtualized containers including Docker images on clustering machines. EKS and GKE are running on the cloud By the way, if you do your best, you can move even with your own machine. ECS is more flexible. There is no need to count, such as secret information management and sジューuling. However, it is very difficult. It is difficult to understand. But if you can use this, it will be.X. CI/CD + VPS + SSHExtra Edition Let's do it in a traditional way. Rent a VPS (Virtual Server). CI/CD service Can I do VPS? If you want to send SSH commands to a descent stone, let's start and stop shell scripts on the server. If you want to bleach the server program directly in 80/443, it’s nice to cross the reverse proxy like nginx. Caddy is easy.That’s why I’m trying to do it. Try it out!

to use REST would include the library https://archive.codeplex.com/?p=json which allows me to make the following conversion: REST value received (I assume this is what you receive): string jsonStr = "{\"solicitud\": {\"dato1\": 1,\"dato2\": 2,\"dato3\": 8}}"; var jObjeto = JsonConvert.DeserializeObject<dynamic>(jsonStr); now to access the values of your json:var dato3 = jObjeto["solicitud"]["dato3"];//8 entoces your quidaria controller as follows:[HttpPost] public void PostConfir(String solicitud){ Ads.GuardaDat("Guarda", "dato24");//Aquí se manda a la BD para provar que si llega al post try { string jsonStr = solicitud;//"{\"solicitud\": {\"dato1\": 1,\"dato2\": 2,\"dato3\": 8}}"; var jObjeto = JsonConvert.DeserializeObject<dynamic>(jsonStr); string dat = jObjeto["solicitud"]["dato25"]; Ads.GuardaDat(dat, "dato25"); } catch (Exception ex) { Ads.GuardaDat(ex.Message, "dato25"); } } now that if it is a dictionary you receive only convert this part then it is the same var jObjeto = JsonConvert.DeserializeObject<dynamic>(solicitud["solicitud"]); do not forget to include the name space: using Newtonsoft.Json;Greetings

As @ Thatenti, the most likely cause is the building of the server, which will redirect all requests to Pope Public.The simplest and fastest decision to connect through public <script type="text/javascript" src="{{ asset('/js/app.js') }}"></script>  <link rel="stylesheet" type="text/css" href="{{ asset('/css/app.css') }}"> Substitution <script type="text/javascript" src="{{ asset('/public/js/app.js') }}"></script>  <link rel="stylesheet" type="text/css" href="{{ asset('/public/css/app.css') }}"> and be happy app.js and app.css, respectively, should be placed in the respective folders as a lower version.

In the manifest you can declare that the app requires calls with :<uses-feature android:name="android.hardware.telephony" android:required="true" /> Another way is limiting the size of the screen:<manifest ... > <compatible-screens> <screen android:screenSize="small" android:screenDensity="ldpi" /> <screen android:screenSize="small" android:screenDensity="mdpi" /> <screen android:screenSize="small" android:screenDensity="hdpi" /> <screen android:screenSize="small" android:screenDensity="xhdpi" /> <screen android:screenSize="normal" android:screenDensity="ldpi" /> <screen android:screenSize="normal" android:screenDensity="mdpi" /> <screen android:screenSize="normal" android:screenDensity="hdpi" /> <screen android:screenSize="normal" android:screenDensity="xhdpi" /> </compatible-screens> Here you have the full explanation https://developer.android.com/guide/practices/screens-distribution

If you have the Students model you do not need to assemble the sqlStudents.where("registration = ?", params[:registration]).where("password = ?",params[:password]).order(:name) If you don't have the Students model is better to createclass Student < ActiveRecord::Base self.table_name="students" self.establish_connection :your_connection end

The object you want, you're clearly pointing in the parameter of the method, and under the hood of JSON, the parser built in Spring Boot compares the parameters you're transmitting in the request with the names of the fields of your facility. The password itself creates a new object and fills the fields through the seterns, if there are not all parameters, they will be null

This is not the correct way to proceed. As you’re dealing with an HTTP call, you can’t assume that the app will wait for it to end. Implementations in this way would block the user interface if used in the main thread (the app would appear locked for the user), so the AFNetworking library does not even worry about performing synchronous requests. Imagine that you are carrying information from a car to be displayed on a screen in an iPhone app, what you should do is request the car information in the - (void) viewDidLoad;, and present to the user a loading indicator "Loading..." for example.When loading is finished, that is, in the success block, you should then change views with new data loaded. Here's an example:- (void) viewDidLoad { // Solicita o carregamento do carro, porém não espera um retorno. [self loadCarWithId:carId]; // Exibe indicador de progresso para o usuário. [ProgressHUD show:@"Loading..."]; } (void) loadCarWithId:(NSInteger)carId { NSString *url = [NSString stringWithFormat: @"%@%@", @"http://www.site.com/rest/carro/", carId]; AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager]; manager.responseSerializer = [AFJSONResponseSerializer serializer]; [manager GET:url parameters:nil success:^(AFHTTPRequestOperation *operation, id json) { // Lida com os dados após o carregamento. Carro *carro = [[Carro alloc] init]; carro.idCarro = [json objectForKey:@"id"]; carro.descricao = [json objectForKey:@"descricao"]; // Atualiza a tela com os dados do carro self.carIdLabel.text = carr.idCarro; // Assumindo que existe uma label "carIdLabel" na sua view. self.carDescriptionLabel.text = carro.descricao; // Assumindo que existe uma label "carDescriptionLabel" na sua view. // Você também pode chamar um médoto quando esta requisição for concluída. [self saveCar:carro]; // Remove o indicador de progresso pois o carregamento já foi concluído. [ProgressHUD dismiss]; } failure:^(AFHTTPRequestOperation *operation, NSError *error) { NSLog(@"Erro: \n\n%@", error); // Remove o indicador de progresso pois o carregamento falhou. [ProgressHUD dismiss]; // Avisa o usuário que o carregamento falhou ou tenta denovo. } ]; // Não há retorno pois essa requisição é assíncrona. } // Isso só vai ser executado depois que a requisição for concluída // já que está sendo chamado dentro do block de success. (void) saveCar:(Carro)carro { [[NSUserDefaults standartUserDefaults] setObject:carro forKey:@"savedCar"]; //Isso é apenas um exemplo, não funciona pois o objeto Carro precisa ser desserializado para ser salvo no user defaults. } EDIT:Added example of activity indicator through ProgressHUD: https://github.com/relatedcode/ProgressHUD

Since you have a custom route (i.e. get ':id/new', to: 'reservations#new', as: 'new_reservation') you have to specify the url in the helper form_for:<%= form_for(@reservation, url: new_reservation_path, html: { role: "form" }) do |f| %>

It is possible and there is a dozen solutions for it on the internet.Mind two things:It will be difficult for you to enable options for any and all OS, as there are numerous.New OS arise and the script will not be able to identify them, and a constant revision of the solution is required, whatever.If possible, try to base yourself on other factors for your code decision.
