How to check available dates in laravel and mongo - php

Question

I am developing a hotel booking availability check using laravel and mongodb. I am confused to write query to find available dates. I tried a method but it is like between and. I am not sure query is correct or not.
I have included laravel raw query and mongo query in this question. Both are same.
Why query is not correct?
Because, Guest checking on 2017-09-02 and checkout on 2017-09-05. Currently I am fetching data like 2017-09-02 >= checkin_from && 2017-09-05 <= checkin_from. If 2017-09-02 is the checkin_from date then, this is correct. But if checkin_from is 2017-08-25 and reserve_to is 2017-09-06. Here dates 2017-09-02 to 2017-09-05 includes. In this case how will we check?
Is this possible with query?
Or
Array 1: Fetch all the bookings and store in an array.
Array 2: Then prepare date (checkin and checkout date from frontend) using DatePeriod and DateInterval and store in an array. Then check matching array(1 & 2).
Which method do I follow?
Query Currently I am using
$bookings = Booking::raw(function ($collection) use ($dateBegin, $dateEnd) {
return $collection->aggregate([
[
'$match' => [
'cabinname' => 'test',
'checkin_from' => ['$gte' => $dateBegin, '$lte' => $dateEnd],
'is_delete' => 0,
],
],
[
'$project' => [
'beds' => 1,
'dormitory' => 1,
'sleeps' => 1,
'status' => 1,
'has status' => [
'$in' => ['status', ['1', '4', '5', '7']]
]
],
]
]);
});
Mongo Query
db.booking.aggregate([
{
$match: {
"cabinname" : 'Test',
"checkin_from" : {$gte :[ new Date ('2017-09-01') ], $lte : [ new Date ('2017-09-03') ] },
"is_delete" : 0,
}
},
{
$project: {
"beds" : 1,
"cabinname":1,
"checkin_from":1,
"reserve_to":1,
"has status" : {
$in: [ "status", ['1', '4', '5', '7'] ]
}
}
}
])
Data from database
{ "_id" : ObjectId("5888fbd5d2ae672245fb5f79"), "cabinname" : "Test", "checkin_from" : ISODate("2017-08-29T22:00:00Z"), "reserve_to" : ISODate("2017-09-03T22:00:00Z"), "beds" : "8" }

Answer 1

My query is not working because of wrong conditions. I have updated the conditions now I am getting exact results.
{checkin_from:{$lte: new Date ('2017-09-02')}, reserve_to:{$gt: new Date ('2017-09-02')}}
$bookings = Booking::raw(function ($collection) use ($dateBegin, $dateEnd) {
return $collection->aggregate([
[
'$match' => [
'cabinname' => 'test',
'checkin_from' => ['$lte' => $dateBegin],
'reserve_to' => ['$gt' => $dateBegin],
'is_delete' => 0,
],
],
[
'$project' => [
'beds' => 1,
'dormitory' => 1,
'sleeps' => 1,
'status' => 1,
'has status' => [
'$in' => ['status', ['1', '4', '5', '7']]
]
],
]
]);
});
