What is the approach if want to add a new attribute to the Product(Model/Data/DTO) in SAP Commerce Cloud and
wanna to access it in Spartacus (using Spartacus ProductService)?
How to introduce the attribute to the Product model in Spartacus and get it populated with the value from the backend?
This question can be seen as a general question how to apply this requirement to all models and keeping the models in sync between backend and frontend.
Thank you in advance.
In order to fetch additional attributes, you can configure the endpoint. See https://sap.github.io/cloud-commerce-spartacus-storefront-docs/connecting-to-other-systems/#configuring-endpoints for more information. There's no need to convert (normalize) the data necessarily, but you could do this as well. This is covered in the same documentation. And you could even replace the standard OCC adapters by a custom adapter if you need to adapt a 3rd party backend.
Once the data is loaded from the backend, it will be stored in the central store, and exposed by the facade without limitation. You might however want to enhance the default typing, in order to benefit from type-safety and not fallback to any. You can do this with the following:
// intro custom typing
interface CustomProduct extends Product {
customAttribute?: string;
}
// use typing for the observed data
product$: Observable<CustomProduct> = this.currentProductService.getProduct()

I added a new type of image format 3d in my commercewebservices-spring.xml.
I want to access this new format in my product-images.component in Product Detail page, something like:
<ng-container *ngIf="mainImage$ | async as main">
<div *ngIf="main.3d as 3d">
But I get an 'unresolved variable', so I guess I need to add this new format elsewhere in spartacus or there is something I'm missing.
Could anyone help with this? Thanks a lot in advance.
there are a couple of steps you'd need to do:
Make sure that the image has been exposed in the OCC api. The OCC endpoints has a configurable fields mapping, that you can use to control the response. You need to verify if your 3d property is exposed. I'm also not sure if you add this as a new property to the backend product model and if it's a media container or a media. But I assume you figure that out.
Make the Spartacus adapter aware of the new field mapping, this is documented in https://sap.github.io/spartacus-docs/connecting-to-other-systems/#configuring-endpoints. You basically configure the required field, so that the data is requested and automatically stored inside the product state in Spartacus.
Implement the UI. I'm not sure if you like to add the 3d image as part of other thumbs/images, or that you need a dedicated UI for 3d images. If it's completely replacement of the product images, the easiest thing is to replace the current cms ProductImagesComponent mapping, i.e.:
providers: [
provideDefaultConfig(<CmsConfig>{
cmsComponents: {
ProductImagesComponent: {
component: Custom3dImagesComponent
}
}
})
]
This is documented at https://sap.github.io/spartacus-docs/customizing-cms-components/
There are alternatives for each step, but these are most straightforward.
If you look at ProductImageNormalizer (https://sap.github.io/spartacus/injectables/ProductImageNormalizer.html#source) you can see that the mapping is slightly different: either image.primary.<format> or image.gallery[n].<format>
Also, bear in mind that the format codes used in the DTO are mapped in the SAP Commerce side. There is an ImageFormatMapping concept, which maps from the actual media format used in the data model in SAP Commerce to the format strings used in the DTO.
In cumulocity cockpit you can specify data point attributes like a display name, unit, value range etc in a so called "data point library". I wonder how I can use these attributes when developing custom dashboard widgets.
I figured out that there is a fragmentType c8y_Kpi for API requests and a class called c8yKpi in the JS client lib which provides all necessary functions. It works fine in my custom widets, but the API/JS class are not documented.
Is there any (official, documented, supported) way to request attributes from the "data point library" via API or JS client library?
These kind of "internal" structures are not documented officially but like you already did you can of course use them in your code.
The risk coming with using undocumented structures are that they might change and then you would need to adapt your code.
Like you already found out yourself the way to get them on API is to call inventory with fragmentType=c8y_Kpi
/inventory/managedObjects?fragmentType=c8y_Kpi
No: currently there is no official, documented and support API for accessing the data point library.
I am creating Cars store in Asp.Net for my school.
I built an Api Method:
[HttpGet("api/brands/{brandName}/models")]
public IActionResult Get(string brandName)
{
{
var model = _context.getBrandByName(brandName);
return Ok(model.Models.ToList());
}
}
An it works when I am checking it with Postman.
Now I would like User to choose brandName from selection list in the website and show him avaliable models.
In other words I dont know how to use this Api to get Data displayed.
Any help will be strongly appreciated
RESTful Web services are one way of providing interoperability between computer systems on the Internet. REST-compliant Web services allow requesting systems to access and manipulate textual representations of Web resources using a uniform and predefined set of stateless operations.
from Wikipedia.
This means, the REST API's only concern is to provide the data to work in a uniform and predefined set of operations, where those operations take the HTTP Verb that was used in consideration.
in your example, your GET route, should only be api/brands/{brandName}
the default in rest api, http verbs say:
GET - getting one element or a list
POST - creating
PUT - updating
DELETE - removing
in your application, the best approach would be something like:
GET /api/brands will get ALL existing brands
GET /api/brands/<brand_name> will get just one brand
POST /api/brands will create a new brand
PUT /api/brands will edit an existing brand
DELETE /api/brands will delete an existing brand
from your question:
Now I would like User to choose brandName from selection list on the website
the website would then request a GET to the route /api/brands to get the list of all of the brands.
This is the REST API part, it concerns ONLY in providing the right data to the system that request it.
if you want to create a website in order to CONSUME this data, you can easily create a new web project in your solution and request the data that the API provides, making the Website completely "blind" from where the data comes from, as it only asks for the data itself.
Making the whole system much easier for updated and maintainability.
In other words I dont know how to use this Api to get Data displayed.
The main purpose of REST API is to expose data not to display it by using any kind of UI framework.
If you think you need to manage the full stack of your application end-to-end. I mean from User interface to your database then you must think at implementing the V of the MVC pattern bu return a view and not just a data. ASP.Net Core can help you with that. Follow this tutorial, it explains a lot about this pattern in ASP.Net Core MVC.
Is there a way to retrieve the tax rules in magento via soap v1?
Right now i'm keeping a duplicate "hard copy" in my order management software for the logistics department, but i'd like to be able to get and set it via the soap api if possible...
Is this possible?
Currently I use
function getTaxIds()
{
$taxids['1'] = 'NL BTW 19%';
$taxids['2'] = 'US BTW 8.375%';
return $taxids;
}
from which I copied the matching id's from the magento backend... but this feels hackish tome and forces manual updates.
Is there a way to retrieve it without going through the pain of extending the magento api?
No, Magento doesn't provide an API for Tax.
You can look at:
Creating a Custom API or Extending the Core API
or just make a simple script that resides on Magento server that will display the data you need as json/xml and make a call to that file.
I am working on a content platform that should provide semantic features such as querying with SPARQL and providing rdf documents for the contained content.
I would be very thankful for some
clarification on the following
questions:
Did I get that right, that an entity
hub can connect several semantic
stores to a single point of access?
And if not, what is the difference
between a semantic store and an
entity hub?
What frameworks would you use to
store content documents as well as
their semantic annotation?
It is important for the solution to be able to later on retrieve the document (html page / docs such as pdf, doc,...) and their annotated version.
Thanks in advance,
Chris
The only Entityhub term that I know is belong to Apache Stanbol project. And here is a paragraph from the original documentation explaining what Entityhub does:
The Entityhub provides two main services. The Entityhub provides the
connection to external linked open data sites as well as using indexes
of them locally. Its services allow to manage a network of sites to
consume entity information and to manage entities locally.
Entityhub documentation:
http://incubator.apache.org/stanbol/docs/trunk/entityhub.html
Enhancer component of Apache Stanbol provides extracting external entities related with the submitted content using the linked open data sites managed by Entityhub. These enhancements of contents are formed as RDF data. Then, it is also possible to store those content items in Apache Stanbol and run SPARQL queries on top of RDF enhancements. Contenthub component of Apache Stanbol also provides faceted search functionality over the submitted content items.
Documentation of Apache Stanbol:
http://incubator.apache.org/stanbol/docs/trunk/
Access to running demos:
http://dev.iks-project.eu/
You can also ask your further questions to stanbol-dev AT incubator.apache.org.
Alternative suggestion...
Drupal 7 has in-built RDFa support for annotation and is more of a general purpose CMS than Semantic MediaWiki
In more detail...
I'm not really sure what you mean by entity hub, where are you getting that definition from or what do you mean by it?
Yes one can easily write a system that connects to multiple semantic stores, given the context of your question I assume you are referring to RDF Triple Stores?
Any decent CMS should be assigning documents some form of unique/persistent ID to documents so even if the system you go with does not support semantic annotation natively you could build your own extension for this. The extension would simply store annotations against the documents ID in whatever storage layer you chose (I'd assume a Triple Store would be appropriate) and then you can build appropriate query and presentation layers for querying and viewing this data as required.

Do you want to implement a traditional CMS extended with some Semantic capabilities, or do you want to build a Semantic CMS? It could look the same, but actually both a two completely opposite approaches.
It is important for the solution to be able to later on retrieve the document (html page / docs such as pdf, doc,...) and their annotated version.
You can integrate Apache Stanbol with a JCR/CMIS compliant CMS like Alfresco. To get custom annotations, I suggest creating your own custom enhancement engine (maven archetype) based on your domain and adding it to the enhancement engine chain.
https://stanbol.apache.org/docs/trunk/components/enhancer/
One this is done, you can use the REST API endpoints provided by Stanbol to retrieve the results in RDF/Turtle format.
