RethinkDb query current date time between two date columns - mysql

Question

Sorry if this a really a basic/noob question, but I am really new to rethinkDb coming from SQL.
(1)
Below is the query in SQL that I wanted to convert into ReThinkDb. This may be really simple, but I cannot make it right.
SQL equivalent:
select *
from reservations
where
room_id = 'b1a7ddd3-ddfd-4624-8e85-79b47fb19f99' and
now() between reservation_start and reservation_end
RethinkDb Query (with error):
r.db("myDb").table("reservations").filter(function(doc){
return
doc("room_id").eq("b1a7ddd3-ddfd-4624-8e85-79b47fb19f99")
.and( r.now().between(doc("reservation_start ").date(), doc("reservation_end").date()) )
}
)
I just want to return the reservations scheduled today, or ongoing if it is already started but not yet finished (end date-time).
(2)
Reservations have a column or field for attendees which is a list/array of name/email:
attendees: [
{"name": "Attendee 1", "email": "attendee1#test.com"},
{"name": "Attendee 2", "email": "attendee2#test.com"},
{"name": "Attendee 3", "email": "attendee3#test.com"},
]
I would like to add a filter to check that an email exists in the list of attendees.
It is like querying for: The email attendee2#test.com has a reservation today for room 101.
If querying with attende email is not possible or complicated... I don't mind as I can do the checking in my application. What matters is the rethinkdb query equivalent for now() between dateColumnStart and dateColumnEnd.
Update: Added sample data stored in DB (RethinkDB)
{
"attendees": [
{
"email": dummyUser101#gmail.com, »
"name": "Dummy User 101"
} ,
{
"email": dummyUser102#gmail.com, »
"name": "Dummy User 102"
}
] ,
"id": "45qum29cel0cm4ejl2obi6pttj" ,
"room_id": "7cc8e51d-e3fa-4d84-b7e6-9ebf8975754a" ,
"reservation_end": "2018-11-23T02:00:00" , //10AM (GMT8)
"reservation_start": "2018-11-19T00:00:00" , //8AM (GMT8)
"details": "Week event 8AM-10AM Test"
}
{
"attendees": [
{
"email": dummyUser103#gmail.com, »
"name": "Dummy User 103"
} ,
{
"email": dummyUser101#gmail.com, »
"name": "Dummy User 101"
} ,
{
"email": dummyUser102#gmail.com, »
"name": "Dummy User 102"
}
] ,
"id": "6ejq8h6tvlpnjiskvt4kthfmss_20181123T060000Z" ,
"room_id": "7cc8e51d-e3fa-4d84-b7e6-9ebf8975754a" ,
"reservation_end": "2018-11-23T07:00:00" , //3PM (GMT8)
"reservation_start": "2018-11-23T06:00:00" , //2PM (GMT8)
"details": "Test Reservation"
}
Thanks!

You cannot use between in the filter. Between gets you all documents between two keys. See docu here: https://www.rethinkdb.com/api/javascript/between/
What you need is the "during" keyword.
r.db("myDB").table("reservations").filter(function(doc){
return doc("room_id").eq("b1a7ddd3-ddfd-4624-8e85-79b47fb19f99")
.and( r.now().during(
r.ISO8601(doc("reservation_start"),{defaultTimezone:"+08:00"}),
r.ISO8601(doc("reservation_end"),{defaultTimezone:"+08:00"})))
}
)
