I have an object stored in arangodb which has additional inner objects, my current use case requires that I update just one of the elements.

}
]
}
I want to change just one of the products stock value
{
"sellingPrice": "95.00",
"inStock": "10",
"discount": "5%",
"name": "School Shirt Blue",
"code": "SKITO293949495",
"warehouseId": "723468998682"
}
Like update store product stock less 1 where store id = x, something to this effect
FOR store IN stores
FILTER store._key == "837108415472"
FOR product IN store.products
FILTER product.code == "SKITO293949495"
UPDATE product WITH { inStock: (product.inStock - 1) } IN store.products
Apart from the above possibly it makes sense to store product as a separate document in collection store_products. I believe in NOSQL that is the best approach to reduce document size.
Found answer
here arangodb-aql-update-single-object-in-embedded-array and there
arangodb-aql-update-for-internal-field-of-object
I however believe it is best to maintain separate documents and rather use joins when retrieving. Updates easily

I'm trying to update a jsonb array in Postgres by replacing the entire array. It's important to note, I'm not trying to add an array to the object, but simply replace the whole thing with new values. When I try the code below, I get this error in the console
error: cannot replace existing key
I'm using Nodejs as server-side language.
server.js
//new array with new values
var address = {
"appt": appt,
"city": city,
"street": street,
"country": country,
"timezone": timezone,
"coordinates": coordinates,
"door_number": door_number,
"state_province": state_province,
"zip_postal_code": zip_postal_code
}
//query
var text = "UPDATE users SET info = JSONB_insert(info, '{address}', '" + JSON.stringify(address) + "') WHERE id=$1 RETURNING*";
var values = [userid];
//pool...[below]
users table
id(serial | info(jsonb)
And this is the object I need update

],
"door_number": "9999",

}';
whole array
update json_update_t set info['address'] = '[{

I have found the answer for this. Going through some of my older apps I coded, I stumbled upon the answer. It's not JSONB_INSERT but JSONB_SET. Notice the difference. The later will replace the entire key and not insert or add to the object.
JSONB_INSERT --> insert
UPDATE users SET info = JSONB_insert(info, '{address,-1}', '" + JSON.stringify(address) + "',true) WHERE id=$1 RETURNING*
JSONB_SET --> set and replace
UPDATE users SET info = JSONB_SET(info, '{address}', '" + JSON.stringify(address) +"') WHERE id=$1 RETURNING*
I have an array of documents, that have more or less same structure. But I need find fields that present in all documents. Somethink like:
{
"name": "Jow",
"salary": 7000,
"age": 25,
"city": "Mumbai"
},
{
"name": "Mike",
"backname": "Brown",
"sex": "male",
"city": "Minks",
"age": 30
},
{
"name": "Piter",
"hobby": "footbol",
"age": 25,
"location": "USA"
},
{
"name": "Maria",
"age": 22,
"city": "Paris"
},
All docs have name and age. How to find them with ArangoDB?
You could do the following:
Retrieve the attribute names of each document
Get the intersection of those attributes
i.e.
LET attrs = (FOR item IN test RETURN ATTRIBUTES(item, true))
RETURN APPLY("INTERSECTION", attrs)
APPLY is necessary so each list of attributes in attrs can be passed as a separate parameter to INTERSECTION.
Documentation:
ATTRIBUTES: https://www.arangodb.com/docs/stable/aql/functions-document.html#attributes
INTERSECTION: https://www.arangodb.com/docs/stable/aql/functions-array.html#intersection
APPLY: https://www.arangodb.com/docs/stable/aql/functions-miscellaneous.html#apply
below is a example of the search results returned from Azure Search after searching for everything in the gift department (default)
{
"id": "1",
"type": "trousers",
"department": "gift",
"description": "This is the description of the item"
}
{
"id": "2",
"type": "toy",
"department": "gift",
"description": "This is the description of the item"
}
{
"id": "3",
"type": "shirt",
"department": "gift",
"description": "This is the description of the item"
}
The result set required should be ordered by type in this order- toy,shirt,trousers. As you can see the result is not a simple orderby "type" field asc/desc. the expected result should be
{
"id": "2",
"type": "toy",
"department": "gift",
"description": "This is the description of the item"
}
{
"id": "3",
"type": "shirt",
"department": "gift",
"description": "This is the description of the item"
}
{
"id": "1",
"type": "trousers",
"department": "gift",
"description": "This is the description of the item"
}
How do i go about doing this - written descriptions and/or code snippets would be fine?
Assuming you're using .Net SDK for performing the search, you can use OrderBy property of SearchParameters to define the ordering criteria.
Assuming your type field is sortable, you can try something like:
var searchParameters = new SearchParameters();
searchParameters.OrderBy = new List<string>()
{
"type desc"
};
I am new to web development and am about half way through a full-stack web development course. How would I go about calling the value of the data stored with the source: "Rotten Tomatoes"?
I have tried Ratings[1].Value and it does not seem to work.
var movieObject = JSON.parse(body);
console.log('Rotten Tomatoes Rating: ', movieObject.Ratings[1].Value);
Body Content:

Your call is correct, so it must be something in the setup. Best guess is that you're calling JSON.parse() on an object that has already been converted to an object.
I have an index on algolia, each document like this.

I want to implement autocomplete on this.
However, when i see the demos present in algolia dashboard, i found out that it returns the complete documents.
I want to only match on user.displayName, place.name, and title
and return only these fields as suggestions in the autocomplete results instead of complete documents, which match.
I know I can create separate indexes for users, places;
But is this possible with only a single index??
Did you had a look at http://algolia.com/doc/tutorials/search-ui/autocomplete/auto-complete/ ?
It shows how to have a custom display from an index.
To match on on user.displayName, place.name, and title
you can configure the "searchable attributes" from the algolia dashboard.
