Research direction
Start by reproducing the BusinessPriority and MetricView model definitions shown in the issue, focusing on the relationship entry point and how the primary-key attribute is looked up. Done means a model whose database column is named id but whose Python attribute is row_id can be queried through the relationship without requiring an id attribute.
Written by the indexing model from the issue text.
Description
class BusinessPriority(client.Model):
metric_views: List['MetricView'] = orm.relationship('MetricView', secondary='business_priority_metrics_link')
class MetricView(client.Model):
"""Data around metric view for Ops Insight"""
__tablename__ = 'metric_view'
row_id: Union[Column, int] = Column(name='id', type_=BigInteger, primary_key=True, autoincrement=True)
I get
"errors": [
{
"message": "type object 'MetricView' has no attribute 'id'",
"locations": [
{
"line": 8,
"column": 9
}
],
"path": [
"allBusinessPriorities",
"edges",
0,
"node",
"metricViews"
]
},
But if I change
row_id: Union[Column, int] = Column(name='id', type_=BigInteger, primary_key=True, autoincrement=True)
to
id: Union[Column, int] = Column(name='id', type_=BigInteger, primary_key=True, autoincrement=True)
The join and query works well.
