I need help again. Can anybody tell my why I get this error? I use Flask and pony orm and python 3.4. I have few files.
users.py

user = select(o for o in models.Users if o.email == e_mail)[:]
print(user)

ValueError: Attribute Users.request is required
How this may to fix? Thank you!
This error can happen if you defined User.request attribute as Required, but in the table the corresponding column is actually optional (that is, nullable). During loading of an object, Pony checks if the object's internal state is consistent. Since the value of a required attribute is missed, Pony generates an exception.
I think that we need to improve Pony behavior in one of two ways here:
Even if an attribute is required, Pony should allow loading of null values for this attribute from the database.
Another alternative is to make error message more clear.

I have unittest for api use Marshmallow in flask 1.1.2 and python 3.8 as bellow
schema.py
class ListSchema(Schema):
id = fields.Integer()
name = fields.String()
gone_date = fields.Function(lambda data: data.gone_date.timestamp())
main_service.py
class MainService:
#classmethod:
def get_list(cls):
list_schema = ListSchema()
list_data, total = Class.function_get_list_data
list_data = list_schema.dump(list_data, many=True)
When i run pytest for function get_list
mock = [(1, 'Name_1', datetime.datetime(2020, 8, 20, 0, 0))], 10
mock_data = mock.Mock(return_value=mock)
with mock.patch.object(Class, 'function_get_list_data', mock_data):
response = MainService.get_list()
I alway get error add lambda function in schema
AttributeError: 'tuple' object has no attribute 'gone_date'
How to pass or test via function lambda in this case. I have try catch with raise unittest.skip but it not my expectation. My function still work normally, only error when apply unittest. Thanks for help.
Edit:
This trace back:

I have two models which are as follows:
class PostUser(models.Model):
user_id = models.CharField(max_length=1000,blank=True,null=True)
reputation = models.CharField(max_length = 1000 , blank = True , null = True)
def __unicode__(self):
return self.user_id
def indexing(self):
obj = PostUserIndex(
meta = {'id': self.id},
user_id = self.user_id,
reputation = self.reputation,
)
obj.save(index = 'post-user-index')
return obj.to_dict(include_meta=True)
class Posts(models.Model):
user_post_id = models.CharField(max_length = 1000 , blank = True , null = True)
score = models.CharField(max_length = 1000 , blank = True , null = True)
owner_user_id = models.ForeignKey(PostUser,default="-100")
def __unicode__(self):
return self.user_post_id
def indexing(self):
obj = PostsIndex(
meta = {'id': self.id},
user_post_id = self.user_post_id,
score = self.score,
owner_user_id = self.owner_user_id,
)
obj.save(index = 'newuserposts-index')
return obj.to_dict(include_meta=True)
The way I am trying to index my data is as follows:
class PostUserIndex(DocType):
user_id = Text()
reputation = Text()
class PostsIndex(DocType):
user_post_id = Text()
score = Text()
owner_user_id = Nested(PostUserIndex)
Then i try to run the following method to index data:
def posts_indexing():
PostsIndex.init(index='newuserposts-index')
es = Elasticsearch()
bulk(client=es, actions=(b.indexing() for b in models.Posts.objects.all().iterator()))
I have tried different approaches by manually entering the nested properties and also changing from doctype to inner doc of PostUser but still I am getting the weird error.

You are calling .save in your indexing methods which will save the document to elasticsearch and then you are also passing it to bulk to accomplish the same, the save is extra.
You are also assigning an instance of PostUser to owner_user_id instead of properly serializing it by calling the indexing method on it (without the save inside):
def indexing(self):
obj = PostsIndex(
meta = {'id': self.id, 'index': 'newuserposts-index'},
user_post_id = self.user_post_id,
score = self.score,
owner_user_id = self.owner_user_id.indexing(),
)
return obj.to_dict(include_meta=True)

Trying to perform an UPSERT on an array of values to a PostgreSQL > 9.5.
Trying to build the statement as in the SQLALchemy docs, but there is no explanation about how to do it for an array instead of a single row. The insert statement builds properly so I suppose it's possible to do so with the on_conflict_do_update function.
Having this code :
stock_table = Table("stock_history", metadata,
Column('date', sqlalchemy.types.NVARCHAR(length=255), primary_key=True),
Column('product_id', sqlalchemy.types.INTEGER(), primary_key=True),
Column('product_sku', sqlalchemy.types.NVARCHAR(length=255)),
Column('on_hand_qty', sqlalchemy.dialects.postgresql.DOUBLE_PRECISION()),
Column('available_qty', sqlalchemy.dialects.postgresql.DOUBLE_PRECISION()),
Column('output_qty', sqlalchemy.dialects.postgresql.DOUBLE_PRECISION())
)
stock_today = pandas.read_sql_query(queryStock, odoo_engine)
insert_stmt = sqlalchemy.dialects.postgresql.insert(stock_table).values(stock_today)
upser_stmt = insert_stmt.on_conflict_do_update(
index_elements=['date', 'product_id'],
set_=stock_today.to_dict(orient='dict')
)
I'm getting the following error:
AttributeError: 'StrSQLCompiler' object has no attribute 'visit_on_conflict_do_update'
During handling of the above exception, another exception occurred:

What I'm ding wrong? Is there a better way to do an upsert?
Thanks!
You are trying to get string representation of Insert-object that has no proper bind, if we write
db_uri = make_url('your-postgres-db-uri-here')
engine = create_engine(db_uri)
upser_stmt.bind = engine
print(upser_stmt)
it works
We can also create insert statement with bind specified
insert_stmt = sqlalchemy.dialects.postgresql.insert(stock_table,
bind=engine).values(stock_today)
upser_stmt = insert_stmt.on_conflict_do_update(
index_elements=['date', 'product_id'],
set_=stock_today.to_dict(orient='dict')
)
I am running the following config for neo4j:
neo4j - 3.0.0
py2neo - 2.0.8
neomodel - 2.0.2
Finally, the code I try to run is:
class User(neomodel.StructuredNode):
user_id = neomodel.IntegerProperty(unique_index=True, required=True)
name = neomodel.StringProperty()
phone_number = neomodel.StringProperty()
user = User(user_id=6, name='Sourabh Dev', phone_number='9711237840').save()
I don't understand, why I keep getting this strange error. Am I doing something wrong here or should I use py2neo instead of neomodel?

Two points here:
Existing Neomodel doesn't support the Neo4j 3.0
Cypher syntax has changed in 3.0, so the error raises.
In 2.x , MATCH n RETURN n
In 3.0 , MATCH (n) RETURN n
Node n is enclosed in braces.
