6 months ago The error you're encountering, TypeError: string indices must be integers, not 'str', suggests that the application is attempting to access elements of a string using string keys, which is only valid for dictionaries or lists. This typically happens when the data structure expected is a list of dictionaries (where each dictionary represents a row from the CSV file, and keys are column headers), but instead, a string or incorrect format is being processed.
To resolve this, ensure your CSV file is correctly parsed into a list of dictionaries. You can use the pandas library to easily convert a CSV file into this format:
import pandas as pd
# Assuming 'csv_file' is the path to your CSV file
df = pd.read_csv(csv_file)
records = df.to_dict(orient='records')
# 'records' is now a list of dictionaries, each representing a row from the CSV.After parsing the CSV file into the correct format, you can iterate over records and access each column value by its header name, which should align with the expected data structure in your application and prevent the TypeError.
If the issue persists after ensuring the CSV is correctly parsed and the data structure is as expected, it might be necessary to review the specific steps or code handling the upload process for further discrepancies.
