I have a custom module in which i want to import some of the updated data but getting an error
Unknown error during import: <class 'KeyError'>: 'field1'
at row 2 Resolve other errors first
I am getting this error in some of the fields not all.
Below are the type and description and parameters of the field in which i am getting this error:-
field1 = fields.Many2one(comodel_name="a.b", string="Field1", required=False, )
field2 = fields.Many2one(comodel_name="b.c", string="Field2", required=False, )
field3 = fields.Char('Field3', size=30, required=True)
field4 = fields.Char('Field4', size=30)
field5 = fields.Char('Field5', size=30, required=True)
After including these fields in export and import resolve this issue but if i remove any of the fields in export and import of data gives this issue again. Why is this happening?
Is this error related to migration or something else i am missing? Do anyone have any idea how to solve this issue?

You have two where and two = in your update query.
val query2 = "Update audit Set status='test' where product='D'"
I'm using pg.8000 (Postgres) and trying to run the following SELECT query
cursor.execute(
"""
SELECT orders.name, orders.order_price, orders.selling_price, orders.earnings
FROM member, orders
WHERE member.id=orders.member_id
AND member.name = %s
""",
member_username
)
Where member.username is a String.
But I am getting the following error.
pg8000.core.ProgrammingError: ('ERROR', 'ERROR', '42P18', 'could not determine data type of parameter $2', 'postgres.c', '1350', 'exec_parse_message', '', '')
However, when I run same query using GUI tool, everything runs fine and I get the results. What is the problem?
You passed the parameter wrong, you should give a tuple, a list or a dictionary
Example with a tuple:
cursor.execute(
"""
SELECT orders.name, orders.order_price, orders.selling_price, orders.earnings
FROM member, orders
WHERE member.id=orders.member_id
AND member.name = %s
""",
(member_username,)
)
Example with a list:
cursor.execute(
"""
SELECT orders.name, orders.order_price, orders.selling_price, orders.earnings
FROM member, orders
WHERE member.id=orders.member_id
AND member.name = %s
""",
[member_username]
)
Example with a dictionary:
cursor.execute(
"""
SELECT orders.name, orders.order_price, orders.selling_price, orders.earnings
FROM member, orders
WHERE member.id=orders.member_id
AND member.name = %(mname)s
""",
{'mname' : member_username}
)

I have these validation rule in Drools Expert which I have tested and works fine:
package com.myapp.validationPackage
import com.myapp.model.*;
declare Message
type : String
text : String
end
function Message error(String text) {
Message message = new Message();
message.setType("ERROR");
message.setText(text);
return message;
}
rule "First Validation"
ruleflow-group "Entity Validation"
when
Entity( $h : history )
not ( exists EntityHistory(closeDate == null) from $h
)
then
insert( error("Entity must be open") );
end
Now I want to use this rule in a workflow but give me this error when I try to build the .rf file on Eclipse:
Unable to resolve ObjectType 'Message' : [Rule name='RuleFlow-Split-XX'] ..
How should I use the delcared type to avoid the error?
Thanks.
