jd-flask-uploads 0.3.1

replace for flask-uploads

jd-flask-uploads

作为 flask-uploads 的替代品，因为 flask-uploads 在 Pypi上没有更新版本，从github上源码安装不太方便。

安装

pip install jd-flask-uploads

用法

from jd_flask_uploads import UploadSet, IMAGES

# Upload Sets
# An “upload set” is a single collection of files. You just declare them in the code:
photos = UploadSet('photos', IMAGES)


# And then you can use the save method to save uploaded files and path and url to access them. For example:

@app.route('/upload', methods=['GET', 'POST'])
def upload():
    if request.method == 'POST' and 'photo' in request.files:
        filename = photos.save(request.files['photo'])
        rec = Photo(filename=filename, user=g.user.id)
        rec.store()
        flash("Photo saved.")
        return redirect(url_for('show', id=rec.id))
    return render_template('upload.html')

@app.route('/photo/<id>')
def show(id):
    photo = Photo.load(id)
    if photo is None:
        abort(404)
    url = photos.url(photo.filename)
    return render_template('show.html', url=url, photo=photo)
