In Fhir, how i can create relationship between resource Patient and resource location(room, bed...)? I can´t find out.
Use the encounter resource to represent where the patient is

What is the value of aws_instance.example.id as I don't see an attribute called id for an instance resource (https://www.terraform.io/docs/providers/aws/d/instance.html)
The second link points to documentation about a data source.
In the page https://www.terraform.io/intro/getting-started/dependencies.html, "${aws_instance.example.id}" is referring a resource, not a data source (data sources are preceded by data.)
Here is the documentation about aws_instance you're looking for:
https://www.terraform.io/docs/providers/aws/r/instance.html#id
It is very important to differentiate between resources and data sources in Terraform ;)
From the page you linked:
id is set to the ID of the found Instance.
In addition to the attributes listed
Is there any way to get the name of a relationship given the from and to entities?
I have a fairly dynamic piece of code that needs to Associate or Disassociate entities. In order to call these functions, I need to know the name of the relationship. I am not sure how to determine the relationship name just given the two entities.
For example, my code might need to disassociate an account with a contact. How can I determine the relationship name of "account_primary_contact"?
In the interest of answering the question despite my not understanding why you would want to do this:
foreach (OneToManyRelationshipMetadata relationshipMetaData in primaryEntityMetadata.ManyToOneRelationships)
{
if (relationshipMetaData.ReferencingEntity == relatedEntity.LogicalName)
{
string relationshipName = relationshipMetaData.SchemaName;
//Do something with your relationship?
}
}
Where primaryEntityMetadata is of type EntityMetadata and ReferencingEntity is of type Entity. Then use similar logic for checking Many to One relationships.
I have a core data model like so:
SALES_REP <--->> CUSTOMER <---->> PURCHASE_AGREEMENT <<------->> PRODUCTS
I can get the entity description for the Purchase Agreement and I can get the relationships (toCustomer and hasProducts)
[NSEntityDescription relationshipsByName];
but is it possible to get the Sales_Rep as well or do I have to pull that through the CUSTOMER entity?
Thanks
According to your diagram, SALES_REP isn't directly related to PURCHASE_AGREEMENT, it's only linked via CUSTOMER. That means SALES_REP doesn't know anything about PURCHASE_AGREEMENT on its own. So yes, you'll have to move on to the entity description for CUSTOMER and ask it for its relationshipsByName. I'm not sure what you're trying to do here, but it would be easy to recursively look up relationships on an entity, then its related entities, and their related entities, etc, until you don't find any new ones.
I have two entity objects, USER and GROUP. GROUP contains a ManyToMany relationship to USER, but that relationship is not bidirectional.
My problem is that I need to find out all of the USERs that are members of a list of GROUPs. If I could reverse the relationship so that the USER contained the relationship to GROUP, I could do this easily, but I can't seem to figure out how to write the JPQL to go the other way.
Can someone out there point me in the right direction?
Thanks
The following seems to work:
select distinct u from User u, Group grp where grp in (?1) and u member of grp.users
I have a resource called "Item" having the following fields :
Id
Name
Description
I want the user to be able to Get Items from the database whether by specifying the id or name.
eg, if I have this entry in the database : (1,House, this is a House) corresponding to (id,name,description), then if the user send a Get request specifying that
id=1
or
name="table"
this should return the entry : (1,Table, this is a table).
The question is, can I do this in restlet ?
can I have the router routing /Item/{itemId} and /Item/{itemName} routed to the same ItemResource class ? in this case, should I have two implementations for the getrepresentation function ?
You can route /Item/{itemId} and /Item/{itemName} to the same resource class, but as the commenter wrote (nearly a year ago!), you run the risk of ambiguity if the id and name namespaces aren't disjoint. A better design would be to have two resources:
/Item?name=MyName
/Item/1234
The first of these would be search resource that returns all items with name MyName. The second would simply look up the unique item 1234.
You could implement this with one resource class, but it would look neater as two separate resource classes (possibly with a common abstract superclass).
