Description

Bug fix for #6179

I confirmed that it works fine to download these files (below) in a query page of Redash by manual test:

• csv
• tsv
• excel

How is this tested?

• Unit tests (pytest, jest)
• Manually

@masayuki038 Thanks for this PR. 😄

It looks like it needs some adjustment to the formatting, in order to pass our CI checks:

tests/query_runner/test_influx_db.py:1:1: I001 [*] Import block is un-sorted or un-formatted
tests/query_runner/test_influx_db.py:13:5: F401 [*] `redash.query_runner.influx_db.InfluxDB` imported but unused

@justinclift Thanks for your following up. I fixed the unused import issue and pushed the branch again. However, it failed...

Run docker-compose logs
  docker-compose logs
  shell: /usr/bin/bash -e {0}
  env:
    NODE_VERSION: 16.[2](https://github.com/getredash/redash/actions/runs/6440340439/job/17489465013?pr=6505#step:10:2)0.1
Couldn't find env file: /home/runner/work/redash/redash/.env
Error: Process completed with exit code 1.

Should I add .env to this branch ?

Huh, that check should not have run. I'll take a look at it later. For now you can just ignore the failing check

[guidopetri]

Would you mind rewriting these as pytest tests? We want to move our codebase away from unittest.

This looks great, thanks so much @masayuki038 ! I left one more comment but it's a nit. I'm good with merging if you don't want to change the names, but I'll wait until tomorrow to merge in case you do :)

[guidopetri]

nit: can we rename the tests to be more descriptive? Maybe something like test_influxdb_result_types_with_rows and test_influxdb_result_types_with_no_rows_are_string?

[guidopetri]

Thanks so much @masayuki038 !
