NJsonSchema C# - Remove $ref fields and replace by the actual structure - c#

I'm using NJsonSchema to convert a normal Json to Schema.
However, NJsonSchema returns the Schema with $ref fields, but I want to have the actual structure.
For example:
{
"$schema": "http://json-schema.org/draft-04/schema#",
"type": "object",
"properties": {
"Property1": {
"$ref": "#/definitions/Property1"
},
"Property2": {
"$ref": "#/definitions/Property2"
},
"Property3": {
"type": "array",
"items": {
"$ref": "#/definitions/Property3"
}
},
"Property4": {
"type": "array",
"items": {
"$ref": "#/definitions/Property4"
}
}
},
"definitions": {
"Property1": {
"type": "object",
"properties": {
"Property1_1": {
"type": "string"
},
"Property1_2": {
"type": "boolean"
},
"Property1_3": {
"type": "integer"
},
"Property1_4": {
"type": "integer"
}
}
},
"Property2": {
"type": "object",
"properties": {
"Property2_1": {
"$ref": "#/definitions/Property2_1"
},
"Property2_2": {

}
}
},
"Property2_1": {
"type": "object",
"properties": {
"Property2_1_1": {
"type": "array",
"items": {
"$ref": "#/definitions/Property2_1_1"
}
},
"Property2_1_2": {
"type": "array",
"items": {
"$ref": "#/definitions/Property2_1_2"
}
},
"Property2_1_3": {
"type": "array",

"dtm_file_name_ext": {

}
}
Got the above JSON using:
JsonSchema bodySchema = JsonSchema.FromSampleJson(jsonStr);
string schemaStr = bodySchema.ToJson();
How can I remove these references and replace to the actual structures?
Such as:
{
"$schema": "http://json-schema.org/draft-04/schema#",
"type": "object",
"properties": {
"Property1": {
"type": "object",
"properties": {

"Property1_2": {
"type": "boolean"
},
"Property1_3": {
"type": "integer"
},
"Property1_4": {
"type": "integer"
}
}
},
"Property2": {
"type": "object",
"properties": {
"Property2_1": {
"type": "object",
"properties": {
"Property2_1_1": {
"type": "array",
"items": {
"type": "object",
"properties": {
"filename": {
"type": "string"
},
"interface": {
"type": "string"
},
"_Comment": {
"type": "string"
}
}
}
},
"Property2_1_2": {
"type": "array",
"items": {
"type": "object",
"properties": {
"filename": {
"type": "string"
},
"interface": {
"type": "string"
},
"_Comment": {
"type": "string"
}
}
}
},
"Property2_1_3": {
"type": "array",
"items": {
"type": "object",
"properties": {
"filename": {
"type": "string"
},
"interface": {
"type": "string"
}
}
}
},
"Property2_1_4": {
"type": "array",
"items": {
"type": "object",
"properties": {
"filename": {
"type": "string"
},
"interface": {
"type": "string"
}
}
}
}
}
},
"Property2_2": {
"type": "object",
"properties": {
"dtm_file_name": {
"type": "string"
},
"dtm_file_name_ext": {
"type": "string"
},
"_Comment": {
"type": "string"
}
}
}
}
},
"Property3": {
"type": "array",
"items": {
"type": "object",
"properties": {
"offset": {
"type": "integer"
},
"value": {
"type": "string"
}
}
}
},
"Property4": {
"type": "array",
"items": {
"type": "object",
"properties": {
"attr_name": {
"type": "string"
},
"offset": {
"type": "integer"
}
}
}
}
}
}
Is there any method that does that inside NJsonSchema or some other way?

NjsonSchema Validation If Property1 is equal to Something then require Property2

I seem to not be able to get const or enum working as part of an if-then-else JSON schema validation.
They seem to be interchangeable when 1 validation value is concerned. (Reference)
Here is my JSON schema
{
"$schema": "http://json-schema.org/draft-07/schema#",
"title": "Test_Schema",
"description": "A schema for validating a test object",
"type": "object",
"additionalProperties": false,
"properties": {
"GeneralData": {
"type": "object",
"description": "Advsor and admin customer information",
"properties": {
"Name": {
"type": [ "string", "null" ],
"description": "Customer's advisor name"
},
"Age": {
"type": [ "string", "null" ],
"description": "Customer's advisor email"
},
"Location": {
"type": [ "string", "null" ],
"description": "The advisor's manager email'"
}
},
"required": [ "Name", "Location", "Age" ]
},
"ClientData": {
"type": "object",
"description": "Customer's information",
"additionalProperties": false,
"properties": {
"Title": {
"type": [ "string", "null" ]
},
"Forename": {
"type": [ "string", "null" ]
},
"Surname": {
"type": [ "string" ]
}
},
"required": [ "Title" ],
"if": {
"properties": {
"Forename": { "enum": [ "Soameonea" ] }
},
"required": [ "Forename" ]
},
"then": { "required": [ "Surname" ] },
"else": false
}
}
}
If Forename = "Someone" I want Surname to be required.
Here is my jsonObject after serialization:
{
"GeneralData": {
"Name": "Not Relevant",
"Age": "Not Relevant",
"Location": "Not Relevant"
},
"ClientData": {
"Title": "SomeTitle",
"Forename": "Someone",
"Surname": null
}
}
Validation code:
internal void ValidateDataObjectOnSchema()
{
var dataObject = PopulateDataObject();
var json = JsonConvert.SerializeObject(dataObject);
var result = GetSchema().Validate(json);
var errors = result.Select(x =>
{
return new Errors() { Title = x.Property, Description = x.Schema.Description };
});
var i = errors;
}
internal JsonSchema GetSchema()
{
return JsonSchema.FromFileAsync("Test/testSchema.json").Result;
}
Right now it still requires Surname, even though the enum Soameonea != Someone and I only require Title. <== Issue1
In the JSON schema if I set "Surname":{"type":["string","null]} then the error disappears and still I don't get the error if I then change the if condition for the Forename enum to "Someone". <== Issue 2
I cannot get a different validation output if I replace Enum with Const, So if I can get one to work I'm sure the other will follow.
I've found several answers to this question (Answer 1), I try to implement the same thing and for some reason, it fails in my case.
What am I missing?
In the JSON schema if I set "Surname":{"type":["string","null]} then the error disappears
A property with a null value still has a value. If you want to say that the property value must not only exist, but not be null, then add "type": "string" to your then condition.
Update:
As #Relequestial mentioned in one of the comments it seems NJson Schema only supports up to Draft 04, this is why if-then-else did not work and implication should be used instead. Below is my solution with an alternative package.
The same code and json work with the package Newtonsoft.Json.Schema (Reference)
Code:
internal void ValidateDataObjectOnSchemaWithNewtonSoftJson()
{
var dataObject = PopulateDataObject();
var settings = new JsonSerializerSettings()
{
NullValueHandling = NullValueHandling.Ignore
};
var jsonDataObjectString = JsonConvert.SerializeObject(dataObject, settings);
JObject jsonDataObject = JObject.Parse(jsonDataObjectString);
var jsonSchemaFile = File.ReadAllText("Test/testSchema.json");
var schema = JSchema.Parse(jsonSchemaFile);
;
IList<ValidationError> messages;
var result = jsonDataObject.IsValid(schema, out messages);
var errors = GetReadableResult(result, messages);
}
private List<Errors> GetReadableResult(bool result, IList<ValidationError> messages)
{
var errors = new List<Errors>();
if (!result)
{
foreach (var error in messages)
{
if (error.ChildErrors.Count > 0)
{
errors.Add(
new Errors()
{
Path = error.ChildErrors.FirstOrDefault()?.Path,
Kind = error.ChildErrors.FirstOrDefault()?.Message
});
}
else
{
errors.Add(new Errors()
{
Path = error.Path,
Kind = error.Message
});
}
}
}
return errors;
}
JsonSchema:
{
"$schema": "http://json-schema.org/draft-07/schema#",
"title": "Test_Schema",
"description": "A schema for validating a test object",
"type": "object",
"additionalProperties": false,
"properties": {
"GeneralData": {
"type": "object",
"description": "Advsor and admin customer information",
"properties": {
"Name": {
"type": [ "string", "null" ],
"description": "Customer's advisor name"
},
"Age": {
"type": [ "string", "null" ],
"description": "Customer's advisor email"
},
"Location": {
"type": [ "string", "null" ],
"description": "The advisor's manager email'"
}
},
"required": [ "Name", "Location", "Age" ]
},
"ClientData": {
"type": "object",
"description": "Customer's information",
"additionalProperties": false,
"properties": {
"Title": {
"type": [ "string", "null" ]
},
"Forename": {
"type": "string"
},
"Surname": {
"type": [ "string" ]
}
},
"required": [ "Title" ],
"if": {
"properties": {
"Forename": { "enum": [ "Someone" ] }
},
"required": [ "Forename" ]
},
"then": { "required": [ "Surname" ] },
"else": {}
}
}
}
The only addition would be to make the GetReadableResult recursive for Errors which have multiple child items.

I am using an API to make requests to to a process.
The response from the server is not always exactly the same size or dimension to compare it to an array.
Response look like this in json...

What is the best practice / correct way to create this as an object in C#?
Do I create a class?
Do I create it as an array?
I know that I have seen a few questions with answers related to this but none of them talk about best practice.
The easiest thing that comes to mind is using visual studio's paste special ability. That creates a class based off of a piece of Json or XML that you have in your clipboard.

nested aggregations filtering

I have my document indexed with locations nested,
{
"name": "name 1",
"locations": [
{
"region": "region1",
"city": "city1",
"suburb": "suburb1"
},
{
"region": "region2",
"city": "city2",
"suburb": "suburb2"
},
{
region": "region1",
"city": "city5",
"suburb": "suburb4"
}]
}
I have my query as
{
"query": {
"nested": {
"path": "locations",
"query": {
"bool": {
"must": [
{
"term": {
"locations.region.keyword": {
"value": "region1"
}
}
}
]
}
}
}
}
}
I want aggregate only cities for region1. I've tried nested aggregations, nested with filter aggregations, and with reverse nested. Nothing seems to work. The problem is since documents come with other regions in the locations collection, everything get aggregated even cities that don't belong to region1.
any ideas?
EDIT:
Mappings:
"my_index": {
"mappings": {
"my_type": {

Assuming your mapping is correct as per your usage in the query
You may use the below mentioned query to use filters in your aggregation.
{
"query": {
"match_all": {}
},
"aggs": {
"city_agg": {
"nested": {
"path": "locations"
},
"aggs": {

"locations.region.keyword": "region1"
}
},

"terms": {
"field": "locations.city.keyword",
"size": 100,

}]
}

Elasticsearch NEST 5.x Koelnerphonetic not matching

UPDATE
I changed the approach of the question
I'm trying to apply phonetic search with koelner phonetics and also ngram is used.
Index configuration I'm using:
{
"testnew": {
"settings": {
"index": {
"number_of_shards": "5",
"provided_name": "testnew",
"creation_date": "1489672932033",

"replace": "false",
"type": "phonetic",
"encoder": "koelnerphonetik"
}
},
"analyzer": {
"koelnerPhonetik": {
"type": "custom",
"tokenizer": "koelnerPhonetik"
},
"ngram_analyzer": {
"type": "custom",
"tokenizer": "ngram_tokenizer"

},
"tokenizer": {

"symbol"
],
"min_gram": "2",
"type": "ngram",
"max_gram": "20"
}
}
},
...
}
}
}
}
}
Ive got one document that looks like this:
{
"_index": "testnew",
"_type": "person",
"_id": "3",
"_score": 1,
"_source": {
"name": "Can",
"fields": {
"phonetic": {
"type": "string",
"analyzer": "koelnerPhonetik"
}
}
}
It is mapped like this:
GET testnew/person/_mapping
"name": {
"type": "text",
"analyzer": "koelnerPhonetik"
}
Why cant I find 'Can' by searching for 'Kan' in this query?
GET testnew/person/_search
{
"query": {
"match": {
"name.phonetic": {
"query": "Kan"
}
}
}

Deploy IIS Website with CloudFormation template

I have a Visual Studio (C#) deployment package (.zip) that I have pushed up to my S3 storage.
I want to run my CloudFormation script and have it create an instance of an IIS server (I have the script for this) and then deploy the Visual Studio web site to it from the S3 storage.
I'm looking for an example of the temple json that would do that
I have a template that does something similar to what you are looking for. Below is a template that I use. It may be more than you need, because it has an auto scaling group, but it will get you started. Basically, you need the IAM user to interact with cloud formation. The script in the UserData starts cf-init, which does the stuff in the metadata section.
