Problem Description
Diesel doesn't generate joinable! if two foreign keys in a table refence the same table
What are you trying to accomplish?
Define relationship between two tables.
What is the expected output?
diesel::table! {
child (id) {
id -> Text,
parent_one_id -> Text,
parent_two_id -> Text,
}
}
diesel::table! {
parents (id) {
id -> Text,
}
}
diesel::joinable!(child -> parents (parent_one_id));
diesel::joinable!(child -> parents (parent_two_id));
diesel::allow_tables_to_appear_in_same_query!(
child,
parents,
);What is the actual output?
diesel::table! {
child (id) {
id -> Text,
parent_one_id -> Text,
parent_two_id -> Text,
}
}
diesel::table! {
parents (id) {
id -> Text,
}
}
diesel::allow_tables_to_appear_in_same_query!(
child,
parents,
);Are you seeing any additional errors?
No. Output is as expected:

Steps to reproduce
Use this migration (up.sql):
create table parents (
id text not null primary key
);
create table child (
id text not null primary key,
parent_one_id text not null references parents(id),
parent_two_id text not null references parents(id)
);Checklist
