$ python manage.py makemigrations $ python manage.py migrate $ python manage.py runserver Your RESTful django server will be available from the 127.0.0.1:8000 address. Here is some information about our restful server: • It exposes an /upload endpoint which accepts POST requests for uploading files. • It has CORS enabled so you can send requests from different doamins without getting blocked by the Same Origin Policy. Prerequisites This tutorial makes use of Ionic 4 with Angular and TypeScript so you need to the following prerequisites: • Node.js and npm installed on your system. You can simply head to the official website and get the binaries for your operating system. • Working knowledge of TypeScript and Angular. Remont akpp 01p svoimi rukami engineering.

Now, let's get started! Installing Ionic CLI v4 Let's install Ionic CLI 4 which is required to generate Ionic 4 projects. Open a new terminal and run the following command.

$ ionic start The CLI will interactively prompt you for some information about your project such as the name (Enter fileuploadapp or any name you choose) and the starter template (Select blank which will give you a starting project with a single page) Next type Enter! The CLI will start generating the files and installing the dependencies from npm. When prompted if you want to Install the free Ionic Appflow SDK and connect your app? (Y/n) Just type n for now. Importing HttpClientModule We'll need to use HttpClient to send a POST for uploading files to the RESTful server so we need to import HttpClientModule in our application module. Open the src/app/app.module.ts file and the following changes.

> ng generate page upload CREATE src/app/upload/upload.module.ts (543 bytes ) CREATE src/app/upload/upload.page.scss (0 bytes ) CREATE src/app/upload/upload.page.html (133 bytes ) CREATE src/app/upload/upload.page.spec.ts (691 bytes ) CREATE src/app/upload/upload.page.ts (256 bytes ) UPDATE src/app/app-routing.module.ts (451 bytes ) [OK] Generated page! You can access this page from 127.0.0.1:4200/upload. Installing and Setting up ng2-file-upload We'll make use of the ng2-file-upload package which provides some directives for handling file upload in Angular.

First install the package from npm using the following command. $ ionic serve Head over to the 127.0.0.1:8100 address then select and drop some files and click on the UPLOAD FILES button: CORS stands for Cross Origin Resource Sharing.

If you are building applications with Django and modern front-end/JavaScript technologies such as Angular, React or Vue, chances are that you are using two development servers for the back-end server (running at the 8000 port) and a development server (Webpack) for your front-end application. When sending HTTP requests from your front-end application, using the browser's fetch API, the Axios client or the jQuery $.ajax() method (a wrapper for the JavaScript XHR interface), to your back-end API built with Django REST framework the web browser will throw an error related to the Same Origin Policy. Allows client applications to interface with APIs hosted on different domains by enabling modern web browsers to bypass the Same origin Policy which is enforced by default.
