Hi, when I'm executing query in repl in such way:
(d/q "[:find
[?Post ...]
:in
$
$comment
[?Post_value_0 ...]
:where
[?Post :IModel/typeName ?Post_value_0]
(or-join
[?Post ?Comment_text_value_3]
[(datomic.api/q
\"[:find [?Comment_uid_2 ...] :in $ :where
[?Comment_by_text_1 :Comment/text _]
[?Comment_by_text_1 :IModel/uid ?Comment_uid_2]
]\"
$comment)
[?Comment_uid_2 ...]]
[(datomic.api/q
\"[:find [?Comment_uid_2 ...] :in $ :where
[?Comment_by_text_1 :Comment/text _]
[?Comment_by_text_1 :IModel/uid ?Comment_uid_2]
]\"
$comment)
[?Comment_uid_2 ...]]
)
[?Post :Post/comments ?Comment_uid_2]
]
" (d/db conn) (d/db connComment) #{"Post"})
The next error is returned:
:db.error/not-an-entity Unable to resolve entity: :Comment/text
My supposing is that query inside datomic.api/q is executed for database returned by (d/db conn) but not (d/db connComment) because if I create :Comment/text for the first database from input list then query is executed without errors.
If to avoid or-join and execute the query in the next way:
(d/q "[:find
[?Post ...]
:in
$
$comment
[?Post_value_0 ...]
:where
[?Post :IModel/typeName ?Post_value_0]
[?Post ?Comment_text_value_3]
[(datomic.api/q
\"[:find [?Comment_uid_2 ...] :in $ :where
[?Comment_by_text_1 :Comment/text _]
[?Comment_by_text_1 :IModel/uid ?Comment_uid_2]
]\"
$comment)
[?Comment_uid_2 ...]]
[(datomic.api/q
\"[:find [?Comment_uid_2 ...] :in $ :where
[?Comment_by_text_1 :Comment/text _]
[?Comment_by_text_1 :IModel/uid ?Comment_uid_2]
]\"
$comment)
[?Comment_uid_2 ...]]
[?Post :Post/comments ?Comment_uid_2]
]
" (d/db conn) (d/db connComment) #{"Post"})
then query is executed without errors.
