Hi,
we run a production ecommerce with an average of ~50k sessions per day. In
the last few weeks we're facing a constant error in production where many
queries are throwing the same error, but in different situations.
The error is: "Cannot resolve keyword <field> into field. Choices are:
..."
I acknowledge that this error is thrown whenever we're trying to join a
table through a field that doesn't exist in the model, but the thing is
that now we daily get thousands of this error in different situations,
apparently in random parts of the code.
I also know that there is the method `prefetch_related` that loads the M2M
relations, but are we supposed to -right now- do a deploy calling this
method in all the places that we get the same error?
Thank you!!
