Error while loading dataset

[nicolamos]

On version 0.9.0 I get the following error on a fresh installation and new data collection, while reading a CSV dataset.

mydataset is a CSV file.

julia> d"mydataset"

Result:

Well that's not what we want! Seems like this is just a case of a typo sneaking in, if you try ]add DataToolkitBase#main, I've just pushed a fix. Do let me know if that fixes it for you 🙂.

For that part now is ok, but still get some error.

I defined the dataset as follows (named machines).

data_config_version = 0
uuid = "511c205b-ffc2-4505-9059-9bdea508edc8"
name = "machines"
plugins = ["store", "defaults", "memorise"]

[[machines]]
uuid = "9ebdc0ee-f448-4158-92fc-b5faa0205687"
description = "machine db"

    [[machines.storage]]
    driver = "filesystem"
    path = "~/cdc-files/db_machines.csv"
    type = "DataToolkitBase.FilePath"

    [[machines.loader]]
    driver = "csv"

But when I try to read it, I get the following error.

ERROR: UnsatisfyableTransformer: There are no storages for "machines" that can provide a IO.
 The defined storages are as follows:
   DataStorage{filesystem}(DataToolkitBase.FilePath)

Hmmm, that's a funky one. Say, do you have an account on the Julia Zulip/Slack where we could chat more? I might be able to better help figure these out over IMs.

So, the issue in the latest comment here was that

type = "DataToolkitBase.FilePath"

meant that it could only provide a FilePath, no IO, but I'm not sure why this line appeared.

At any rate, I'm soon to make a bunch of changes around this, hopefully they'll help.
