The file is already open. open takes a string filename and created an open file object, but you don’t need to do that because objects in request.files are already open file-like objects. portfolios = csv.DictReader(request.files[‘portfolios’])
When storing binary data, use the LargeBinary type. Despite its name, it is appropriate for any sized binary data. data = db.Column(db.LargeBinary) Read the data from the uploaded file in your Flask view. audio.data = request.files[‘data’].read() Rather than storing the data in the database, it’s typically better to store files in the filesystem, and store … Read more

You can compose your payload in your ajax request as so: $(document).ready(function(){ var clicked; $(“.favorite”).click(function(){ clicked = $(this).attr(“name”); $.ajax({ type : ‘POST’, url : “{{url_for(‘test’)}}”, contentType: ‘application/json;charset=UTF-8’, data : {‘data’:clicked} }); }); }); In your flask endpoint, you can extract the value as follows: @app.route(‘/test/’, methods=[‘GET’,’POST’]) def test(): clicked=None if request.method == “POST”: clicked=request.json[‘data’] return … Read more
