I am using the following code to call the NHS Retrieve Reference Data method
var result = await fhirClient.ReadAsync<CodeSystem>(url);
which returns the following Json (this is a snippet of the full json)
concept": [
{
"code": "BOOKED_CLINICAL_NEED",
"display": "Booked more urgently due to clinical need",
"property": [
{
"code": "effectiveFrom",
"valueDateTime": "2019-07-23T17:09:56.000Z"
},
{
"code": "commentIsMandatory",
"valueBoolean": true
},
{
"code": "canCancelAppointment",
"valueBoolean": false
}
]
}
I have used the GetExtensionValue method for other calls when the data is within an extension but I can't find a similar method for properties.
Is there a simple method or do I need to just cast into the required type manually?
Thanks in advance
There is no convenience method for this. However, the properties per concept are a list, so you could for example iterate over the concepts and select the properties with boolean values using regular list methods:
foreach (var c in myCodeSystem.Concept)
{
var booleanProperties = c.Property.Where(p => (p.Value.TypeName == "boolean"));
// do something with these properties
}
or find all concepts that have a boolean property:
var conceptsWithDateTimeProperties = myCodeSystem.Concept.Where(c => c.Property.Exists(p => (p.Value.TypeName == "dateTime")));
Of course you can make your selections as specific as you need.

I have a C# REST API that uses the Hl7.Fhir.R4 library (3.7.0) with a POST method that receives an object of type Hl7.Fhir.Model.Patient:
[ProducesResponseType(StatusCodes.Status200OK)]
[ProducesResponseType(StatusCodes.Status201Created)]
[ProducesResponseType(StatusCodes.Status404NotFound)]
[ProducesResponseType(StatusCodes.Status401Unauthorized)]
[ProducesResponseType(StatusCodes.Status500InternalServerError)]
[HttpPost()]
public async Task<IActionResult> Post(Patient patient)
{
IActionResult status = NotFound();
...
}
The Patient object has a list of extensions:
"extension": [
{
"url": "http://example.com/fhir/extension/patient/origin",
"valueString": "test"
},
{
"url": "http://example.com/fhir/extension/patient/domainId",
"valueInt" : "10"
}...
When receiving the JSON as a parameter in the POST function, all the fields have a better value than those of type 'Hl7.Fhir.Model.DataType':
Extension[0]
Children: {Hl7.Fhir.Model.Extension.<get_Children>d__17}
ElementId: null
NamedChildren: {Hl7.Fhir.Model.Extension.<get_NamedChildren>d__19}
Extension: Count = 0
TypeName: "Extension"
Url: "http://example.com/fhir/extension/patient/origin"
Value: null
Am I missing some decorator or attribute or simply can't the object be directly deserialized?
Did you use the FhirJsonParser from the library to parse the data? You cannot use a regular JSON parser, because it will not be able to handle the FHIR model correctly.
ETA:
As you now mention in your question, the object cannot be directly deserialized, see first part of my response.
Maybe you can take a look at this project to see how it's done there: https://github.com/brianpos/fhir-net-web-api
A content-type "Product" having the following fields:
string title
int qty
string description
double price
Is there an API endpoint to retrieve the structure or schema of the "Product" content-type as opposed to getting the values?
For example: On endpoint localhost:1337/products, and response can be like:
[
{
field: "title",
type: "string",
other: "col-xs-12, col-5"
},
{
field: "qty",
type: "int"
},
{
field: "description",
type: "string"
},
{
field: "price",
type: "double"
}
]
where the structure of the schema or the table is sent instead of the actual values?
If not in Strapi CMS, is this possible on other headless CMS such as Hasura and Sanity?
You need to use Models, from the link:
Link is dead -> New link
Models are a representation of the database's structure. They are split into two separate files. A JavaScript file that contains the model options (e.g: lifecycle hooks), and a JSON file that represents the data structure stored in the database.
This is exactly what you are after.
The way I GET this info is by adding a custom endpoint - check my answers here for how to do this - https://stackoverflow.com/a/63283807/5064324 & https://stackoverflow.com/a/62634233/5064324.
For handlers you can do something like:
async getProductModel(ctx) {
return strapi.models['product'].allAttributes;
}
I needed the solution for all Content Types so I made a plugin with /modelStructure/* endpoints where you can supply the model name and then pass to a handler:
//more generic wrapper
async getModel(ctx) {
const { model } = ctx.params;
let data = strapi.models[model].allAttributes;
return data;
},
async getProductModel(ctx) {
ctx.params['model'] = "product"
return this.getModel(ctx)
},
//define all endpoints you need, like maybe a Page content type
async getPageModel(ctx) {
ctx.params['model'] = "page"
return this.getModel(ctx)
},
//finally I ended up writing a `allModels` handler
async getAllModels(ctx) {
Object.keys(strapi.models).forEach(key => {
//iterate through all models
//possibly filter some models
//iterate through all fields
Object.keys(strapi.models[key].allAttributes).forEach(fieldKey => {
//build the response - iterate through models and all their fields
}
}
//return your desired custom response
}
Comments & questions welcome
This answer pointed me in the right direction, but strapi.models was undefined for me on strapi 4.4.3.
What worked for me was a controller like so:
async getFields(ctx) {
const model = strapi.db.config.models.find( model => model.collectionName === 'clients' );
return model.attributes;
},
Where clients is replaced by the plural name of your content-type.
I'm trying to validate json files which have an element that has a property which contains a value that should exist in another part of the json. I'm using jsonschema Draft 07.
This is a simple little example that shows the scenario I'm trying to validate in my data.
{
"objects": {
"object1": {
"colorKey": "orange"
}
},
"colors": {
"orange": {
"red": "FF",
"green": "AF",
"blue": "00"
}
}
}
How can I validate that the 'value' of colorKey (in this case 'orange') actually exists as a property of the 'colors' object? The data isn't stored in arrays, just defined properties.
For official JSON Schema...
You cannot check that a key in the data is the same as a value of the data.
You cannot extract the value of data from your JSON instance to use in your JSON Schema.
That being said, ajv, the most popular validator, implements some unofficial extensions. One of which is $data.
Example taken from: https://github.com/epoberezkin/ajv#data-reference
var ajv = new Ajv({$data: true});
var schema = {
"properties": {
"smaller": {
"type": "number",
"maximum": { "$data": "1/larger" }
},
"larger": { "type": "number" }
}
};
var validData = {
smaller: 5,
larger: 7
};
ajv.validate(schema, validData); // true
This would not work for anyone else using your schemas.
I have an array of objects from which I need to pass each object separately into async method (process behind is handled with Promise and then converted back to Observable via Observable.fromPromise(...) - this way is needed because the same method is used in case just single object is passed anytime; the process is saving objects into database). For example, this is an array of objects:
[
{
"name": "John",
...
},
{
"name": "Anna",
...
},
{
"name": "Joe",,
...
},
{
"name": "Alexandra",
...
},
...
]
Now I have the method called insert which which inserts object into database. The store method from database instance returns newly created id. At the end the initial object is copied and mapped with its new id:
insert(user: User): Observable<User> {
return Observable.fromPromise(this.database.store(user)).map(
id => {
let storedUser = Object.assign({}, user);
storedUser.id = id;
return storedUser;
}
);
}
This works well in case I insert single object. However, I would like to add support for inserting multiple objects which just call the method for single insert. Currently this is what I have, but it doesn't work:
insertAll(users: User[]): Observable<User[]> {
return Observable.forkJoin(
users.map(user => this.insert(user))
);
}
The insertAll method is inserting users as expected (or something else filled up the database with that users), but I don't get any response back from it. I was debugging what is happening and seems that forkJoin is getting response just from first mapped user, but others are ignored. Subscription to insertAll does not do anything, also there is no any error either via catch on insertAll or via second parameter in subscribe to insertAll.
So I'm looking for a solution where the Observable (in insertAll) would emit back an array of new objects with users in that form:
[
{
"id": 1,
"name": "John",
...
},
{
"id": 2,
"name": "Anna",
...
},
{
"id": 3,
"name": "Joe",,
...
},
{
"id": 4,
"name": "Alexandra",
...
},
...
]
I would be very happy for any suggestion pointing in the right direction. Thanks in advance!
To convert from array to observable you can use Rx.Observable.from(array).
To convert from observable to array, use obs.toArray(). Notice this does return an observable of an array, so you still need to .subscribe(arr => ...) to get it out.
That said, your code with forkJoin does look correct. But if you do want to try from, write the code like this:
insertAll(users: User[]): Observable<User[]> {
return Observable.from(users)
.mergeMap(user => this.insert(user))
.toArray();
}
Another more rx like way to do this would be to emit values as they complete, and not wait for all of them like forkJoin or toArray does. We can just omit the toArray from the previous example and we got it:
insertAll(users: User[]): Observable<User> {
return Observable.from(users)
.mergeMap(user => this.insert(user));
}
As #cartant mentioned, the problem might not be in Rx, it might be your database does not support multiple connections. In that case, you can replace the mergeMap with concatMap to make Rx send only 1 concurrent request:
insertAll(users: User[]): Observable<User[]> {
return Observable.from(users)
.concatMap(user => this.insert(user))
.toArray(); // still optional
}
I am trying to work Ember with Parse.com using
ember-model-parse-adapter by samharnack.
I add added a function to make multiple work search(like search engine) for which I have defined a function on cloud using Parse.Cloud.define and run from client.
The problem is the Array that my cloud response returns is not compatible with Ember Model because of two attributes they are __type and className. how can I modify the response to get response similar to that i get when I run a find query from client. i.e without __type and className
Example responses
for App.List.find() = {
"results":[
{
"text":"zzz",
"words":[
"zzz"
],
"createdAt":"2013-06-25T16:19:04.120Z",
"updatedAt":"2013-06-25T16:19:04.120Z",
"objectId":"L1X55krC8x"
}
]
}
for App.List.cloudFunction("sliptSearch",{"text" : this.get("searchText")})
{
"results":[
{
"text":"zzz",
"words":[
"zzz"
],
"createdAt":"2013-06-25T16:19:04.120Z",
"updatedAt":"2013-06-25T16:19:04.120Z",
"objectId":"L1X55krC8x",
"__type" : Object, //undesired
"className" : "Lists" //undesired
}
]
}
Thanks Vlad something like this worked for me for array
resultobj = [];
searchListQuery.find({
success: function(results) {
for( var i=0, l=results.length; i<l; i++ ) {
temp = results.pop();
resultobj.push({
text: temp.get("text"),
createdAt: temp.createdAt,
updatedAt: temp.updatedAt,
objectId: temp.id,
words: "",
hashtags: ""
});
}
In your cloud code before you make any response, create and object and extract from it the attributes/members you need and then response it. like so:
//lets say result is some Parse.User or any other Parse.Object
function(result)
{
var responseObj = {};
responseObj.name = responseObj.get("name");
responseObj.age = responseObj.get("age");
responseObj.id = responseObj.id;
response.success(responseObj);
}
on the response side you will get {"result": {"name": "jhon", "age": "26", "id": "zxc123s21"}}
Hope this would help you
