I am trying to set dotted keys on an already existing super table. This seems to go wrong during the render method, because the code thinks I want to render everything as a super table.

My code:

import tomlkit

doc = tomlkit.loads("""
[output.netcdf_scalar]
value = 5
""")

output_table = doc["output"]
output_table[tomlkit.key(["csv", "path"])] = "output.csv"

print(tomlkit.dumps(doc))

Output:

csv.path = "output.csv"

[output.netcdf_scalar]
value = 5

Expected:

[output.csv]
path = "output.csv"

[output.netcdf_scalar]
value = 5

In the case of rendering the toml, it will say that the item "csv" is dotted, while "output" is not dotted, and "csv" is a super table, so it will not render "output" as prefix. But just adding the prefix will be wrong, because you actually need to at the [output.csv] table as a head, instead of writing output.csv.path.

I think that the _handle_dotted_key function is in this case not able to indicate that "csv" should not be super:
