You sir helped me solve my confusion on this flask function. Thank you from a Python newbie! No more school boy errors for me.

[dundarylmaz]

with flask version 2.0 instead of filename you use path
], path=image_file_name ....

[investmentapps]

Wrapped this into a HTML page with a file list so the user can click on the filename to download it. Awesome.

[santiagoandresortiz]

what a for anyone newcomers instead of filename parameter for the send_from_directory...its now path

[pronoygomes]

Very helpful tutorials on Flask. Thank you

For those who get a 404 error and are using Windows, you have to start your working directory with "C:" and remove the leading slash. So in this example it would be app.config["CLIENT_IMAGES"] = C:/wsl/projects/pythonise... etc.

Need to add a sticky somewhere about filename= is now path=

[ThilinaWimalapriya]

A very good video. Thanks for the sharing

[berrodriquez]

LEGEND, for the ones who have this error "send_from_directory() missing 1 required positional argument: 'path'", replace filename for path in "send_from_directory(app.config['CLIENT_IMAGES'], path=image_name, as_attachment=True)".

I really enjoy your series Julian, keep up the good work. I think it would be better to connect a button to the path of the files to get them downloaded. A lot of not so tech guys will be frustrated to type the name of the file they want to download.

Hello, please is there a tip to check the orientation of an odt file before upload ? That is to say I would like to check is the user select landscape mode in a dropdown list and he tries to send the file which is not in landscape, I will return a validation error

[alidaghighi]

Pretty helpful! Thanks and keep up buddy!

I want to send a pdf file from one user to another over my website how can I achieve this?

[marc-alexandrepaquet]

Looks like the except part is never triggered, even if you have an error. The send_from_directory seems to handle it.

[naveenbiradar]

Hi,

Can you make video on send files to render inside html like pdf load inside html

[AutomationWithSholz]

isn't it possible to use {{url_for("file")}} here?
