How to Upload Files with Flask Using Python

Hey guys! Welcome back, in this video I will be showing you how to upload files using Python and Flask. We're going to use Flask to build our website, Flask_WTF, and WTForms to create our forms and Werkzeug to securely save our files. There are links down below for the code and the official Flask documentation.
Code Repo: github.com/arpanneupane19/Fla...
Official Flask Documentation: flask.palletsprojects.com/en/...
If you don't know about Flask, Flask is a Python web framework that is lightweight and easy to use. It is a good choice for beginners, and it can be used to create web applications that are scalable. Flask can be used with WTForms to create forms on pages and these forms can be used to upload files as well.

Watched a tones of videos on YT for this but couldn't find anything as perfect as this!! Thanks a lot mate such a crisp and clear video❤❤

[@ArpanNeupaneProductions]

Thank you!!

[@kerimsever6674]

I have been searching for a while and this is the best video by far for a flask upload function

[@ArpanNeupaneProductions]

Thank you for the support!

[@austinallen4184]

“Made it smaller so you could see” 😅 excellent video man, love how fast you go through it, perfect speed. There’s other tuts covering the same content that are 30+ min long and not even as in depth as this

[@hazadus]

Thanks, just what I was looking for!

[@astropgn]

This is awesome! I have an iphone but I use Windows, so it is always a hassle to send files from my phone to my computer. There are apps, but nothing is straightforward. So this helped me a lot. I serve this file locally and whenever I want to send a file from my phone to my computer, I just access the page and send it. So easy

[@ArpanNeupaneProductions]

Awesome!

[@Loving_Earth]

Thanks man , excellent explanation and i subscribed 😉

[@djangodude9252]

Great video man. Very Impressive

Thank you for watching!

[@satishgaire]

Great video!

[@ArpanNeupaneProductions]

Thanks!

[@viserlesetoiles5024]

Thanks to you I finally was able to understand my mistakes. Isolating the form tags from each other by wrapping them inside divs made my "Choose file" button not clickable

[@waiitwhaat]

AMAZING tutorial.

[@magnoliapaz]

Thanks a lot!

[@boringmanager9559]

Would be nice if you said that certain files have to be called in a specific ways. Took me some time to debug because I didn't know index must be in 'templates' file. Anyways, the video is amazing, helped me a lot

[@samirahuseynli6956]

thank you so much! you saved my day!!

[@ArpanNeupaneProductions]

glad it helped!

[@user-py4yz5ik6x]

Great video. I had on question though how would u style the form component in the templates?

[@logukaruna845]

Same as you style the form in html You can use either inline css or external css stylesheet then connect it to the html file. That's it

[@rangabharath4253]

awesome😀

[@Perera006]

Hey bro say I wanted to now use this image through a maze solver I created, how would I output the end image?

[@SirD3fault]

Great video, really well made! Really broke down what you were doing really well. Looking at this, is there some way you'd go about testing this? I'm looking at this right now and am wondering how it could be tested through Pytest

[@joshuachett2504]

Can I adjust this method to allow the user to select 2 input files? Or do I need to take a different approach? They need to be able to open the file browser 2 different times, and select a file and upload it each of those times.

[@NW-lx6dg]

Did you find solution for that?

[@akbarahmadi5066]

excellent

[@angelomilansantos6342]

how about deleting file in static folder?

[@shootahgamez]

How can I link this to a SQLAlchemy database in Flask? My goal is to have a feature where I can upload an image to the database and display it on the front end (like a profile picture that can be updated).

[@shamilaxbaxsky167]

nice

[@MarkDemeter-lc2uk]

Thans but how can I avoid the re-routing after upload? I just wanted to display a flash.

[@NareenThiran]

My validate_on_submit is not working...it says there is no attribute as such

[@rayanemesbah7815]

securefilename might return an empty string so you need to deal with that also

[@elestirensincap1481]

so can we do this inside the zipped folder?

[@ArpanNeupaneProductions]

not sure

[@midonlyadyana2314]

bro how to replace the old file let say by the same file name with the new file? please give me a clue or help me brother

[@ArpanNeupaneProductions]

You can add a new condition where if the old file’s name is equal to the new file’s name, you can find the old file, delete it, and upload the new file. You can do this with the OS library in Python. Look into the documentation.

[@midonlyadyana2314]

@@ArpanNeupaneProductions okay bro i think that was fixed, im using the os.remove to delete the old file first and then resubmit the other file but by the same name file to system. Thanks

[@ArpanNeupaneProductions]

@@midonlyadyana2314 Sweet!

[@christiansnow1193]

does anyone know how I can save the uploaded file into a variable for use in my python file

[@haazmedia]

you could save the file first as shown above, then 'variable = filepath' or something like that. For example, if you uploaded a .csv file, you could read it in as a df using 'df = pandas.read_csv('filepath')

[@Techkvn96]

How can I automatically store files from my folder into the web server? I am building a keylogger and I want to upload the files from my python directory folder into the server and be able to view it there. Please Help
