It's been a while since the question has been asked, but I would also like to know how to use du.callback()
on multiple pages. I have my du.configure_upload()
in my app.py
.
I am able to define the download folder by returning the du.Upload()
in a normal callback
with a specified upload_id
that I get from Input("url", "search")
.
But I need to have a `du.callback()' to trigger other stuff when the upload is finished...
Hi.
What I want to do principally is the following:
Page 1: main.py Here the app is initiated etc
Page 2: upload_agreement.py Here the user can upload a signed and filled agreement. It should be put in a specific folder
"data/$UserName/agreements"
Page 3: upload_images.py Here the user can upload images (Multiple files) These should be put in specific folder
"data/$UserName/images"
I am able to make this work with 2 pages by getting the app instance with dash.get_app(). In this way I use
du.configure_upload(app, output_folder)
However, with 3 pages, I have not found a solution. The problem is that it seems that du.configure_upload(app, output_folder) must be present on the page where the du.Upload component is instantiated. However, when I add
du.configure_upload(app, output_folder)
to Page 3 I get the error:AssertionError: View function mapping is overwriting an existing endpoint function: get
So it seems that the endpoint is defined globally, but still, the du.configure line must be present on each page where I use du.callback. But I cannot have this line present on all pages since that overwrites the endpoint of dash-uploader.
Is there a workaround?
