Nonetype object Not Iterable on using thesaurus

[Pushkalb]

Hi, I tried to use thesaurus, but I'm getting an issue saying "argument of type 'NoneType' is not iterable".
Could anyone help on this?
Thanks!

[sakuranew]

some word‘s equivalences is none but original code have code like “sth in equivalences“,
so you just need to add a condition to ensure this part code doesnt execute when equivalence is none

I had this problem it seems that self.database_object.get_table_by_name(table_name).equivalences in parser.py:711&806 can be NoneType.

You can avoid the bugs by adding these two lines above:

if self.database_object.get_table_by_name(table_name).equivalences is None:
    continue

Why is this variable sometimes NoneType?

• I have no idea.

It seems to be a problem by reading the thesaurus dictionary. In the paper, they indicated:

Ainsi si la table regroupant les informations des étudiants a par exemple pour nom ETUD_UNIV_01, et qu'aucun synonyme n'a donc été automatiquement ajouté à ce nom de table, l'utilisateur pourra rentrer manuellement le mot étudiant comme synonyme [...].

Thus, if the table containing the students' information has, for example, the name ETUD_UNIV_01, and no synonyms have been automatically added to this table name, the user can manually enter the word student as a synonym [...].

Then I tried to get the table chambre when I ask with azertyuiop (random word) to try this feature.

Then I added these lines in the thesaurus dictionary:

chambre|1
(noun)|azertyuiop|randomword

I ran the following command:

python -m ln2sql.main -d database_store/hotel.sql -l lang_store/english.csv -t thesaurus_store\th_english.dat -j output.json -i "What are the azertyuiop with nbLit greater than 3?"

The result is: (it's correct)

SELECT *
FROM chambre
WHERE chambre.nbLit > '3';

I noticed with the following lines in the thesaurus dictionary doesn't work. You need to add another value as above.

chambre|1
(noun)|azertyuiop

I need to figure out the way they retrieve values. Why does it return NoneType? Why doesn't single synonym work?

just let the equivalences =[] rather than Nonetype when initialize the database object

After which line of code(please put the statement) should we place the if condition?

i tried adding after 709 and 805. However the output seems to be different before and after. Please refer to below screenshot

So, Instead of continuing when the self.database_object.get_table_by_name(table_name).equivalences is None, i have tried setting it to empty List.

if self.database_object.get_table_by_name(table_name).equivalences is None:
      self.database_object.get_table_by_name(table_name).equivalences = []

Here is the expected output:

Seems like even the single word works but we have to end it with a pipe as below

chambre|1
(noun)|azertyuiop|

instead of

chambre|1
(noun)|azertyuiop

Change the first few lines in load method in thesaurus.py file to below:

    def load(self, path):
        with open(self._generate_path(path)) as f:
            # content = f.readlines()
            content = f.read().splitlines()

Now its working even id we dont add an extra pipe at the end
