@adrianrjh To use the files uploaded from the browser to the wave server you have to first download it into the wave app. Here is the updated example:
import csv
from h2o_wave import main, app, Q, ui
@app('/')
async def serve(q: Q):
data_rows = []
if 'file_upload' in q.args:
# Since multiple file uploads are allowed, the file_upload argument is a list.
for path in q.args.file_upload:
# To use the file uploaded from the browser to the wave server, download it into the app.
local_path = await q.site.download(path, '.')
with open(local_path) as csvfile:
# Do something with the file located at local_path
# ...
pass
# Update the UI
q.page['example'] = ui.form_card(box='1 1 4 10', items=[
ui.text(f'file_upload={data_rows}'),
ui.button(name='show_upload', label='Back', primary=True),
])
else:
q.page['example'] = ui.form_card(
box='1 1 4 7',
items=[
ui.file_upload(
name='file_upload',
label='Upload!',
multiple=True,
file_extensions=['csv', 'gz'],
max_file_size=10, max_size=15
)
]
)
await q.page.save()
After uploaded csv file, I want to manage the file for make arrays, but the server say that not such file directory. So, i don't know where's the file.
