NameError: name 'anvil' is not defined (client-side)

Anvil Q&A
1

Hi,
I am very new to using Anvil. I am basically trying to load an Excel workbook on the client side and pass it onto a Jupyter notebook on the server side (currently my own machine). I have the following code running on the client side:

from ._anvil_designer import Form1Template
from anvil import *
import anvil.tables as tables
import anvil.tables.query as q
from anvil.tables import app_tables
from anvil.tables import app_tables

class Form1(Form1Template):
  def __init__(self, **properties):
    # Set Form properties and Data Bindings.
    self.init_components(**properties)

    # Any code you write here will run before the form opens.

  def file_loader_1_change(self, file, **event_args):
    """This method is called when a new file is loaded into this FileLoader"""
    tod_data = anvil.server.call('tod_preprocess', file)

self.tod_table.content = anvil.server.call('df_final') # displaying the final dataframe

However, I am getting the following error:

NameError: name 'anvil' is not defined

  • at Form1, line 19

I know this topic is tagged as fixed, but I wanted to know if I am doing anything wrong.

Which line is line 19?

Never mind I see it. It is because your last line is outside the class definition. You need to check the indenting on line 19

You need to import anvil.server since you’re using that in your last line.
