I have this collection in my mongodb database, and when I query data from it, like for example .find("data.Manufacturer":"iPollo") because its nested documents, it returns for me the entire document, is there any way where I could return only the object from the array without like hardcoding it (getting the entire data liste and iterate through it to find the query I am searching for)
One option is using an aggregation pipeline:
db.collection.aggregate([
{$match: {"data.Manufacturer": "iPollo"}},
{$set: {
data: {
$filter: {
input: "$data",
cond: {$eq: ["$$this.Manufacturer", "iPollo"]}
}
}
}
},
{$replaceRoot: {newRoot: {$first: "$data"}}}
])
See how it works on the playground example
I am not sure how to phrase this question properly but basically I have an "Order" Schema and each order model contains an array of product objects created using "Product" Schema
When I create an order, my req.body is this
body: {
orderItems: [ [Object] ],
shippingAddress: {
fullName: '123',
address: '1231',
city: '123',
postalCode: '123',
country: '123'
},
shippingPrice: 0,
paymentMethod: 'Stripe',
itemsPrice: 338,
totalPrice: 338
},
If I log req.body.orderItems, I can see each product object printed

I am making a restful api based on flask and Pymongo. Been trying to query data in a specific shape but having a hard time querying it. Below is my query code.
def track_route(from_time, to_time):
doc = myCol.aggregate([
{"$match":{
"MessageTime":{"$gt": from_time},
"MessageTime":{"$lt": to_time}
}},
{"$group":{
"_id":'$MMSI',
"$MMSI":{"accumulator1":"$ROT"}
}},
{"$project":{"_id":0}}
])
doc_list = [i for i in doc]
return doc_list
It returns this.
pymongo.errors.OperationFailure: The field '$MMSI' must be an accumulator object, full error: {'ok': 0.0, 'errmsg': "The field '$MMSI' must be an accumulator object", 'code': 40234, 'codeName': 'Location40234'}
This is the shape that I want to return.

123456789 and 234567890 are the MMSI value and are the key value for sub documents. How can I query in the shape above? It's nested. If cannot, at least the most similar way.
You have some mistakes in your aggregation, you cannot reference a field as a key, you should put a static field name.
This a correct way to group.
db.collection.aggregate({
"$group": {
"_id": "$MMSI",
"a": { //replace that "a" with any field name you want but not for a $ref
"$push": "$$ROOT" // you need to use an accumulator like $push, and the correct form to reference the whole doc is $$ROOT
}
}
}
Then you can map your info as you wanted. You can test the code here
{
"$replaceRoot": {
"newRoot": {
$arrayToObject: {
$map: {
input: [
"$$ROOT"
],
as: "el",
in: {
"k": {
$toString: "$$el._id"
},
"v": "$$el.a"
}
}
}
}
}
}
Using Laravel 5.4
I am reaching out as I am having a difficult time wrapping my head around this and after searching all day on the internet (and stackoverflow) I have not found a good solution to my problem that works.
Basically, I have a user object, that queries a child object which in turn includes a child object and I need to filter with where on that grandchild object.
It looks like this:
User =>
Pet(1) =>
PetServiceItem <= ServiceItem(1)
PetServiceItem <= ServiceItem(2)
PetServiceItem <= ServiceItem(3)
Pet(2) =>
PetServiceItem <= ServiceItem(1)
PetServiceItem <= ServiceItem(4)
PetServiceItem <= ServiceItem(5)
I'll post the relevant parts of the information so someone can tell me how this might be done.
User Model
class User extends Authenticatable
{
public function pets()
{
return $this->hasMany(Pet::class);
}
}
Pet Model
class Pet extends Model
{
protected $fillable = [
'id',
'user_id',
...];
public function user()
{
return $this->belongsTo(User::class);
}
public function petServiceItems(){
return $this->hasMany(PetServiceItem::class);
}
}
PetServiceItem model
class PetServiceItem extends Model
{
protected $fillable = [
'pet_id',
'service_item_id',
'approved'
];
protected $table = 'pet_service_item';
public function pet()
{
return $this->belongsTo(Pet::class);
}
public function serviceItem()
{
return $this->belongsTo(ServiceItem::class);
}
}
ServiceItem model
class ServiceItem extends Model
{
protected $fillable = [
'id',
...,
'start_date',
'end_date',
'...',
];
public function pets(){
return $this->hasMany(PetServiceItem::class);
}
}
Using Tinker I can do the following:
$user->pets()->with(['petServiceItems', 'petServiceItems.service'])->get()
And get this data:

Now I need to do a where clause on the ServiceItem for the start_date.
I tried:
$user->pets()->with(['petServiceItems', 'petServiceItems.serviceItem'])->where('service_items.start_date', '>=', '2017-01-01')->get()
But, I get this error:
Illuminate\Database\QueryException with message 'SQLSTATE[42S22]:
Column not found: 1054 Unknown column 'service_items.start_date' in
'where clause' (SQL: select * from pets where pets.user_id = 6
and pets.user_id is not null and service_items.start_date >=
2017-01-01)'
How can I use the where clause (or something else if needed) to filter the data I need?

I have figured out that this is the SQL that I want (or close enough approximation):
select * from users
join (select * from pets) pet on users.id = pet.user_id
join (select * from pet_service_item) psi on psi.pet_id = pet.id
join (select * from service_items) si on si.id = psi.service_item_id
join (select * from providers) prov on prov.id = si.provider_id
where si.start_date >= '2017-07-17'
AND si.end_date <= '2017-10-18'
AND prov.id = 2
AND users.id = 6
Where clause use the name of the table and not the model. Try this:
$user->pets()->with(['petServiceItems', 'petServiceItems.serviceItem'])
->where('service_items.start_date', '>=', '2017-01-01')->get();
So, I'm posting this as I never really did get an answer and I ended up with a solution, but not exactly the one I was looking for.
If anyone is interested, in the end, this is how I did it (note: this flattened the data, which for all intents and purposes, worked fine in my scenario).
$services = App\ServiceItem::where('provider_id', '=', $provider->id)
->where('user.user_id', '=', $user->id)
->where('start_date', '<=', $end_date)
->where('end_date', '>=', $start_date)
->orWhereNull('end_date')
->where('pet.pet_user_id', '=', $user->id)
->whereNull('service_items.deleted_at')
->whereNUll('pet.pet_deleted_at')
->join(DB::raw('(select pet_id as psi_pet_id, service_item_id as psi_service_item_id from pet_service_items) psi'), function($join) {
$join->on('psi.psi_service_item_id', '=', 'service_items.id');
})
->join(DB::raw('(select id as pet_id, user_id as pet_user_id, name as pet_name, deleted_at as pet_deleted_at from pets) pet'), function($join) {
$join->on('pet.pet_id', '=', 'psi.psi_pet_id');
})
->join(DB::raw('(select id as user_id, name as user_name, deleted_at as user_deleted_at from users) user'), function($join) {
$join->on('user.user_id', '=', 'pet.pet_user_id');
});
return ['status' => 200, 'services' => $services->get()];
db.employee.insert(
{
_id: 'shop1',
ShopName: 'Londis',
ShopAddress: 'Clea boy',
Owner: 'Tim Byrne',
ShopContactNumber: '0877733121',
Employee: [
{
EmployId: '1',
EmployName: 'Pat Power',
EmployContactNumber: 0876395224,
EmployAddress: 'Lacka Rd',
Salary: 500.00,
Hours: 40,
PayType: 'Cheque',
Wage: 9.00,
EmployeeType: 'Manager'
},
{
EmployId: '2',
EmployName: 'Craig Coad',
EmployContactNumber: 0873347582,
EmployAddress: 'Portlaw',
Salary: 400.00,
Hours: 32,
PayType: 'Bank',
Wage: 8.65,
EmployeeType: 'FloorStaff'
},
{
EmployId: '3',
EmployName: 'Joe Bloggs',
EmployContactNumber: 0861234567,
EmployAddress: 'Waterford',
Salary: 510.00,
Hours: 12,
PayType: 'Cheque',
Wage: 9.50,
EmployeeType: 'Manager'
}]});
I want to update the state of an item for a specific Employee.
For example, I would want to update item 1 to set EmployName = "Patrick Power" for EmployeId = "1" because that employee exists:
db.students.update(
{'_id':'shop1','Employee.EmployId':'1'},
{$set:{'Employee.$.EmployName':'Patrick Power'} }
);
This is what i have been trying to do but it dose not work?
What am i doing wrong ?
This might be helpful to you :
db.collectionName.update({
"_id": "shop1",
'Employee': {
'$elemMatch': {
'EmployId': '1'
}
}
}, {
$set: {
'Employee.$.EmployName': 'Patrick Power'
}
});
