Unable to delete entries

[rule88]

currently developing an API, which all seems to work ok using safrs. However, deleting entries somehow don't seem possible, the following stacktrace is printed:

[2020-09-29 11:20:06,951] ERROR: 'dict' object is not callable

127.0.0.1 - - [29/Sep/2020 11:20:06] "DELETE /user/1/ HTTP/1.1" 500

I am using a MySQL database:

mysql> describe user;
+-------+-------------+------+-----+---------+----------------+
| Field | Type        | Null | Key | Default | Extra          |
+-------+-------------+------+-----+---------+----------------+
| id    | int         | NO   | PRI | NULL    | auto_increment |
| name    | varchar(45) | YES  | UNI | NULL    |                |
+-------+-------------+------+-----+---------+----------------+
mysql> select * from user;
+----+------+
| id | ip   |
+----+------+
|  1 | test |
+----+------+

and the following model:

class BaseModel(SAFRSBase, db.Model):
    __abstract__ = True

class User(BaseModel):
    """
        description: User description
    """
    __tablename__ = "user"

    id = db.Column(db.Integer, primary_key=True, unique=True, nullable=False)
    name = db.Column(db.String(45), unique=True)

Hope you can help me with this as safrs is a real nice way in producing a self documenting API.

Hi,

This seems to be related to python3.8. Can you try with python3.6 ?
I'll fix this asap.

[thomaxxl]

Can you try with the latest commit for 3.8?
I'll have to test this some more though.

[rule88]

Hi @thomaxxl I can confirm that it does work with 3.6, will now try with latest commit on 3.8.

[rule88]

Hi @thomaxxl I now also can confirm that delete operation do work on python 3.8. Thanks for your support !
