Hi, I'm pretty new to Sequel but I'm trying to figure something out:
I have this query that limits the dataset to the current user and it looks
kinda like this:
```
Model
.graph(:access_policies,
{ user_id: user.id, resource_id: :first_account_id) },
{ table_alias: :ap1 })
.graph(:accounts,
{ id: :first_account_id },
{ table_alias: :a1 })
.graph(:access_policies,
{ user_id: user.id, resource_id: :second_account_id },
{ table_alias: :ap2 })
.graph(:accounts,
{ id: :second_account_id },
{ table_alias: :a2 })
.where(Sequel.lit('ap1.id is not null and a1.id is not null'))
.or(Sequel.lit('ap2.id is not null and a2.id is not null'))
```
There's also some code that handles `include=first_account` in the query
string, which does an .eager_graph on `first_account`.
All good, until `dataset.all` gets called -- then I get a `NoMethodError:
undefined method `model' for #<Sequel::Postgres::Dataset: "SELECT * FROM
\"access_policies\"">`
I stepped through the code and it seems to be trying to eager load those
non-eager graphed associations within `EagerGraphLoader`
It loops through this: `datasets = opts[:graph][:table_aliases]`
and `model` is undefined for each of the table_aliases defined by `graph`
(not `eager_graph`)
I'm working on a production legacy codebase, so I'm trying to not break the
auto eager graph stuff -- is there a way I can just tell it which model to
use for the `graph` calls? Or to skip those for the EagerGraphLoader? Or am
I doing it all wrong?
