I have a redis JSON collection and it must to store items unique.
[
{
"name": "John",
"tId": 13,
"phone": "124",
"city":"LA"
},
{
"name": "Jane",
"tId": 14,
"phone": "256",
"city":"NYC"
}
]
In this JSON, I want to keep name unique. The other attributes can be duplicate. However, all collection must only 1 item with name John or whatever.
What kind of index do that? Do I need to use RedisBloom?

i want to create an Api for an order system. I have Ingredients and Products, both have categories which have to match if you want to combine them. So if a user selects a Pizza how can I only load in the ingredients which are available for Pizza, so the user cant select pasta as a Topping on his Pizza.
So if the User selects a Product pizza in extra and extraWo only the ingredients should show up, which are available for pizza
Thank you for your help
Depending on the API structure.
For example:
[
{
"Crust": "NORMAL",
"Flavor": "BEEF-NORMAL",
"Order_ID": 1,
"Size": "M",
"Table_No": 1,
"Timestamp": "2018-12-12T13:42:13.704148+00:00"
},
{
"Crust": "THIN",
"Flavor": "CHEESE",
"Order_ID": 2,
"Size": "S",
"Table_No": 5,
"Timestamp": "2018-12-12T13:42:13.704148+00:00"
},
{
"Crust": "NORMAL",
"Flavor": "CHICKEN-FAJITA",
"Order_ID": 3,
"Size": "L",
"Table_No": 3,
"Timestamp": "2018-12-12T13:42:13.720690+00:00"
}
]
Each pizza would be unique so foo[1]["Crust"] will give you "Normal". Add logic like checking the availability. Have a look at https://docs.djangoproject.com/en/3.1/topics/db/queries/#querying-jsonfield
For example do:
object.filter(pizza__normal='available')
I have an entity like this:
{
"id": "xxxx",
"attributes": [{
"name": "name-01",
"value": "value-01"
}, {
"name": "name-02",
"value": "value-02"
}
]
}
Our "questions" to data usually: Give me entities with attribute or attribute with particular value;
in SQL it was written like as:
select *
from c
where
and array_contains(c.attributes, { "name": "name-01", "value": "value-01" }, true)
and array_contains(c.attributes, { "name": "name-02", "value": "value-02" }, true)
but I would like to extend a model to allow have suggestion of values in each attribute by transform an entity to:
{
"id": "xxxx",
"attributes": [{
"name": "name_01",
"value": "value-01",
"suggestions": ["a", "b", "c"]
}, {
"name": "name_02",
"value": "value-02",
"suggestions": ["a", "d", "e"]
}
]
}
With that structure I would like to ask: Give me all entities that has specified attribute and value equals to "XYZ" or suggestions array contains "XYZ";
In general scenario if always add value into array of suggestions the ask would be "Give me all entities that has specified attribute and suggestions contains XYZ"
N.B. Also I would like to make queries : Give me all entities that has more ALL specified attributes with constraints per each by suggestions?
Please suggest how to write such queries or rebuild a structure of entities in Cosmos DB;
P.S. We can technically switch from SQL to other protocol to better make such queries;
This should be doable using ARRAY_CONTAINS along with iterating the attributes array.
Give me items with value "value-01" or suggestion "f":
SELECT DISTINCT VALUE(c)
FROM c JOIN attr IN c.attributes
WHERE attr["value"] = "value-01" OR ARRAY_CONTAINS(attr.suggestions, "f")
Give me items with value "value-01" or both suggestions "a" and "f":
SELECT DISTINCT VALUE(c)
FROM c JOIN attr IN c.attributes
WHERE attr["value"] = "value-01" OR
ARRAY_CONTAINS(attr.suggestions, "a") AND ARRAY_CONTAINS(attr.suggestions, "f")
I have a json string that I need to modify
{"RecordCount":3,"Top":10,"Skip":0,"SelectedSort":"Seed asc","value":[{"AccountProductListId":22091612871138,"Name":"April 4th 2018","AccountId":256813438078643,"IsPublic":false,"Comment":"Test order sheet","Quantity":3},{"AccountProductListId":166305848801939,"Name":"test","AccountId":256813438078643,"IsPublic":false,"Comment":"","Quantity":1},{"AccountProductListId":21177711287586,"Name":"Test Order sheet","AccountId":256813438078643,"IsPublic":true,"Comment":"the very first sheet","Quantity":2}]}
Inside value the array looks like this:
"value": [{
"AccountProductListId": 22091612871138,
"Name": "April 4th 2018",
"IsPublic": false,
"Comment": "Test order sheet",
"Quantity": 3
}, {
"AccountProductListId": 166305848801939,
"Name": "test",
"IsPublic": false,
"Comment": "",
"Quantity": 1
}, {
"AccountProductListId": 21177711287586,
"Name": "Test Order sheet",
"IsPublic": true,
"Comment": "the very first sheet",
"Quantity": 2
}],
What I need to do is append some data from another table:
AccountProductListId ProductID
21177711287586 97096131867163|32721319938943
22091612871138 97096131867163|145461009584740|130005306921282
166305848801939 8744071222157
As you can see the AccountProductListId is already in the JSON result so I should know which array it should go to. The only problem is I don't know the syntax to merge the ProductID data into its specific array index. The JSON array could have more than 3 items.
Essentially ending up with something like this:
"value": [{
"AccountProductListId": 22091612871138,
"Name": "April 4th 2018",
"IsPublic": false,
"Comment": "Test order sheet",
"Quantity": 3,
"ProductID": "97096131867163|145461009584740|130005306921282"
}, {
"AccountProductListId": 166305848801939,
"Name": "test",
"IsPublic": false,
"Comment": "",
"Quantity": 1,
"ProductID": "8744071222157"
}, {
"AccountProductListId": 21177711287586,
"Name": "Test Order sheet",
"IsPublic": true,
"Comment": "the very first sheet",
"Quantity": 2,
"ProductID": "97096131867163|32721319938943"
}],
Any information would be greatly appreciated. Thanks.
Process with SQL Server
Prior to SQL Server 2016, there is not in-built support to read or write JSON.
Starting SQL Server 2016, you can use OPENJSON rowset function to read JSON and FOR JSON clause to write JSON.
See https://learn.microsoft.com/en-us/sql/relational-databases/json/json-data-sql-server
The approach would be to use OPENJSON to read the JSON string as a rowset, join it with the table to pickup ProductID and use FOR JSON to convert back to JSON.
Process outside SQL Server
Depending on your situation, it might be simpler to parse JSON outside SQL Server. If going that route, then you could
Collect all the AccountProductListIDs from the parsed JSON
Send the collected id to SQL Server via a stored procedure that takes a TVP input and outputs the AccountProductListID -> ProductID mapping
Inject the ProductIDs into JSON object and serialize back to string
I want to create a path which accepts any number of IDs separated with commas. It should accept all the following:
GET /pets/1,2 # returns info about pets with ids 1, 2
GET /pets/4,10,12,124,2 # same, for pets with ids 4, 10, 12, 124, 2
The book "building apis you won't hate" gave me this idea.
How do I do that in swagger?
Swagger 2.0 supports the collectionFormat parameter. From the documentation:
Determines the format of the array if type array is used. Possible values are:
csv: comma separated values: foo,bar
ssv: space separated values: foo bar
tsv: tab separated values: foo\tbar
pipes: pipe separated values: foo|bar
multi: corresponds to multiple parameter instances instead of multiple values for a single instance foo=bar&foo=baz. This is valid only for parameters in "query" or "formData".
Default value is csv.
An example of use can be seen on the documentation:
{
"get": {
"description": "Returns pets based on ID",
"summary": "Find pets by ID",
"operationId": "getPetsById",
"produces": [
"application/json",
"text/html"
],
"responses": { ... }
},
"parameters": [
{
"name": "id",
"in": "path",
"description": "ID of pet to use",
"required": true,
"type": "array",
"items": {
"type": "string"
},
"collectionFormat": "csv"
}
]
}
How do i make custom reorder for products in collection in shopify. i mean for exapmle i have 'test' collection and i want to reorder products in 'test' collection by using product tag i mean i put some tags like 'firstshowup' in some product in 'test' collection so when customer click 'test' collection customer see products which have 'firstshowup' tag first and then see the rest so what iam trying here is reordering using custom reordering not using like order by bestseller or allpabetically or date created s.t
thank you so much guys in advance
Your collection will be made up of Collect objects, which have a position attribute. Assuming you're using a CustomCollection, you can modify the position of the Collects by updating the CustomCollection: http://api.shopify.com/customcollection.html#update
From the examples, to update a collection, you can use:
PUT /admin/custom_collections/#{id}.json
With the following payload:
{
"custom_collection": {
"body_html": "<p>The best selling ipod ever</p>",
"handle": "ipods",
"id": 841564295,
"published_at": "2008-02-01T19:00:00-05:00",
"sort_order": "manual",
"template_suffix": null,
"title": "IPods",
