managed to make it work
Hi, I found something interesting. If you copy and paste the image address in your browser after you upload the image you can paste it and see it enabling a different route like http://127.0.0.1:5002/_uploads/photos/picture.png and with this you can point directly to your application file http://127.0.0.1:5002/_uploads/photos/upload.py or any file on the folder.
I have three questions:
Is this the intended use?
is there any way to prevent this?
is this library supported by someone?
I've done the video on spanish but hope it helps https://youtu.be/jv3BH3PW-iE
This code is not working. One should make a folder named 'templates', which contains the 'index.html'. After that, it works. @KUDANDOU
Anyway, this is a good example.
This code works but as @ClaudioReevas said it creates this "virtual folder" called _uploads which is not visible at all in my project. Even though I have created a folder for uploading images and specified it in my settings.py it doesn't see that path at all. Is there any way to fix it?
Now I am also confused with this problem. According to my understanding "app.config['UPLOADED_PHOTOS_DEST']" should be set as a temporary folder, such as "/tmp". For database use, we need to move the data from this folder to another place, where we used to save the data permanently. I am not so sure if this understanding is correct. But anyway, I want to do it like this.
this helped me out a lot thank you
Thank you so much!
app.config['UPLOADED_PHOTOS_DEST'] = os.getcwd() + '/app/tmp/'The above change will send the photo to a directory other than the current directory.
Thank you very much for the code!
请问，用Flask_uploads做了一个上传手机照片的页面，但偶尔还是会有
raise UploadNotAllowed()
flask_uploads.UploadNotAllowed
想用try/except查找此情况下上传文件的扩展名。
但是：
except UploadNotAllowed as error:
会报错：
NameError: name 'UploadNotAllowed' is not defined
还试过flask_uploads.UploadNotAllowed或flask_uploads，但都说没定义。
请问这里该怎么写？感谢~
I using Flask_uploads to make a page to upload mobile photos,
but occasionally there still be
raise UploadNotAllowed()
flask_uploads.UploadNotAllowed
I want to use try / except to find the extension of the uploaded file.
but:
except UploadNotAllowed as error:
Will report an error:
NameError: name 'UploadNotAllowed' is not defined
I also tried flask_uploads.UploadNotAllowed or flask_uploads, but they all undefined.
What should I write here? thank~
