import {
  Controller,
  Create,
  File,

} from "https://raw.githubusercontent.com/narrowizard/oak-injector/master/mod.ts";
import { FormDataFile } from "https://deno.land/x/[email protected]/multipart.ts";
import logger from "../../../middlewares/logger.ts";
import { format } from "https://deno.land/[email protected]/datetime/mod.ts";
import { exists } from "https://deno.land/[email protected]/fs/exists.ts";

@Restful("/files")
class Files extends Controller {
  @Create()
  async Post(@File("file") file: FormDataFile, @Form("type") type: string) {
    const now = new Date();
    const pathname = `upload/${type}/${format(
      now,
      "yyyyMMdd"
    )}`;
    const filename = `${pathname}/${format(now, "hhmmss")}${Math.round(Math.random() * 1000)}-${file.originalName}`;
    if (file.content) {
      // file content kept in memory
      await Deno.writeFile(filename, file.content);
    } else if (file.filename) {
      // file content written to file
      const exist = await exists(pathname);
      if (!exist) {
        await Deno.mkdir(pathname, { recursive: true });
      }
      await Deno.copyFile(file.filename, filename);
    } else {
      return "";
