Hi all,
At this link here is a seemingly very handy local file picker I would like to use: https://community.plotly.com/t/file-explorer-tree-generator-for-local-files/68732?u=liuto
However, I just can’t seem to get this to work!
Here’s my initial code (I essentially just copied and pasted and threw my own path in here):
import os
from dash_iconify import DashIconify
import dash_mantine_components as dmc
from dash import Dash, html
class FileTree:
def __init__(self, filepath: os.PathLike):
"""
Usage: component = FileTree('Path/to/my/File').render()
"""
self.filepath = filepath
def render(self) -> dmc.Accordion:
return dmc.Accordion(
self.build_tree(self.filepath, isRoot=True),
multiple=True)
def flatten(self, l):
return [item for sublist in l for item in sublist]
def make_file(self, file_name):
return dmc.Text(
[DashIconify(icon="akar-icons:file"), " ", file_name], style={"paddingTop": '5px'}
)
def make_folder(self, folder_name):
return [DashIconify(icon="akar-icons:folder"), " ", folder_name]
def build_tree(self, path, isRoot=False):
d = []
if os.path.isdir(path):
children = self.flatten([self.build_tree(os.path.join(path, x))
for x in os.listdir(path)])
if isRoot:
d.append(
dmc.AccordionItem(
children=children,
label=self.make_folder(os.path.basename(path)))
)
else:
d.append(
dmc.Accordion(children=[
dmc.AccordionItem(
children=children,
label=self.make_folder(os.path.basename(path)))
],
multiple=True)
)
else:
d.append(self.make_file(os.path.basename(path)))
return d
app = Dash()
# FileTree.render() returns a dash mantine components Accordion
app.layout = html.Div(FileTree('/assets').render())
if __name__ == '__main__':
app.run_server(debug=True)I’m looking to just display my assets folder, let users pick what file they want from it. When running the code above, the webpage is simply blank with no display
I’m not incredibly familiar with Dash so please excuse my ignorance. I’m not even sure where to start troubleshooting. Any tips or tricks would be appreciated.
Edit: I’ve also tried a few different ways of representing my file path, such as
r"C:\Users\liutony\source\repos\Dash\assets"which gives me the following error:
[Previous line repeated 4 more times]
File "c:\Users\liutony\source\repos\Dash\app.py", line 44, in build_tree

return func(*args, **kwargs)
^^^^^^^^^^^^^^^^^^^^^

raise TypeError(
TypeError: Required argument `value` was not specified.I’ve also tried using /Users/liuto/source/repos/Dash/assets as my filepath, and while this throws no error, the Dash webpage output continues to be blank.
