Uploader (Python)

Port em Python do pacote PHP coffeecode/uploader de Robson V. Leite. Mantem o comportamento original (validacao por mime/extensao, diretorios YYYY/MM, slug, redimensionamento de imagens) com uma API framework-agnostica baseada em UploadedFile — aceita path em disco ou stream em memoria, com adapters prontos para Flask e FastAPI.

Python port of the PHP package coffeecode/uploader by Robson V. Leite. Same behavior (mime/extension validation, year/month directories, slugged filenames, image resizing) with a framework-agnostic UploadedFile API: accepts a filesystem path or an in-memory stream, with built-in adapters for Flask and FastAPI.

Destaques

• Upload simples de imagens, arquivos e midias
• UploadedFile: abstracao unica para path em disco ou stream
• Adapters: from_flask, from_fastapi, from_stream, from_path, from_dict (compat com PHP $_FILES)
• Gestao de diretorios com esquema de datas (YYYY/MM)
• Validacao por mime-type e extensao
• Redimensionamento e qualidade de imagem (substitui ext-gd por Pillow)

Instalacao

pip install coffeecode-uploader

Requer Python >= 3.9 e Pillow >= 10.

Uso

Flask

from flask import Flask, request
from coffeecode_uploader import Image, UploadedFile, UploaderException

@app.post("/avatar")
def avatar():
    try:
        upload = UploadedFile.from_flask(request.files["image"])
        path = Image("uploads", "images").upload(upload, request.form["name"])
        return {"path": path}
    except UploaderException as e:
        return {"error": str(e)}, 400

FastAPI

from fastapi import FastAPI, File, UploadFile, HTTPException
from coffeecode_uploader import Image, UploadedFile, UploaderException

app = FastAPI()

@app.post("/avatar")
async def avatar(name: str, image: UploadFile = File(...)):
    try:
        upload = UploadedFile.from_fastapi(image)
        path = Image("uploads", "images").upload(upload, name)
        return {"path": path}
    except UploaderException as e:
        raise HTTPException(400, str(e))

Stream em memoria

from io import BytesIO
from coffeecode_uploader import File, UploadedFile

upload = UploadedFile.from_stream(
    BytesIO(pdf_bytes),
    filename="report.pdf",
    content_type="application/pdf",
)
path = File("uploads", "files").upload(upload, "Relatorio Mensal")

Path ja em disco

from coffeecode_uploader import File, UploadedFile

upload = UploadedFile.from_path("/tmp/report.pdf", content_type="application/pdf")
path = File("uploads", "files").upload(upload, "Relatorio")

Compat com $_FILES (PHP-style)

from coffeecode_uploader import File, UploadedFile

upload = UploadedFile.from_dict({
    "name": "report.pdf",
    "type": "application/pdf",
    "tmp_name": "/tmp/upload.pdf",
})
path = File("uploads", "files").upload(upload, "Relatorio")

API

Construtores

Image(upload_dir, file_type_dir, month_year_path=True)
File(upload_dir, file_type_dir, month_year_path=True)
Media(upload_dir, file_type_dir, month_year_path=True)
Send(upload_dir, file_type_dir, allow_types, extensions, month_year_path=True)

upload(file: UploadedFile, name: str, ...)

Retorna a string com o caminho final relativo. Lanca UploaderException quando o tipo MIME ou a extensao nao estao na lista permitida.

• Image.upload(image, name, width=2000, quality=None) — quality aceita {"jpg": 0..95, "png": 0..9}. Padrao: {"jpg": 75, "png": 5}. GIFs sao copiados sem reprocessamento (igual ao PHP).
• File.upload(file, name)
• Media.upload(media, name)
• Send.upload(file, name)

UploadedFile

Helpers

• Cls.is_allowed() (alias Cls.isAllowed()) — lista de mime-types permitidos.
• Cls.is_extension() (alias Cls.isExtension()) — lista de extensoes permitidas.
• Uploader.multiple([...]) — converte lista heterogenea (dict, FileStorage, UploadFile, UploadedFile) em list[UploadedFile].

Migrar de v1.x

A v1 aceitava um dict no formato PHP $_FILES. Em v2 use UploadedFile:

# v1
file_dict = {"name": "x.pdf", "type": "application/pdf", "tmp_name": "/tmp/x"}
File("uploads", "files").upload(file_dict, "Doc")

# v2
upload = UploadedFile.from_dict(file_dict)
File("uploads", "files").upload(upload, "Doc")
