I need to get value from the rapidjson document (reference).
Below is the code:
Document *jsonDocument;
Value& data = jsonDocument["data"];
Any help is appreciated.
The problem here is that jsonDocument is a pointer to Document. To call the operator[], you may:
Value& data = (*jsonDocument)["data"]

Consider the following mapping for a document in ES.
class MyDoc(elasticseach_dsl.Document):
id_info = Object(IdInfo)
class IdInfo(elasticseach_dsl.InnerDoc):
id = Keyword()
type = Keyword()
Using elasticsearch-dsl, there are 2 ways of retrieving a document (that I am interested in):
Using MyDoc.search().query().execute(), that yields Hit objects
Using MyDoc.get(), that yields a MyDoc object
Here is the issue I am experiencing:
When I retrieve the same document from ES, and that document is missing, for example, the type field, I get different behaviours:
When using search(): doc being a Hit object, accessing doc.type raises a KeyError
When using get(): doc being a MyDoc object, accessing doc.type simply returns None
To workaround this discrepancy, I would like to convert a Hit instance to a MyDoc instance, so that I can always use the doc.type syntax without any errors being raised.
How can I do that?
Alternatively, is there a way that I could access Hit instances with the same behaviour as MyDoc instances?
dict_hit = hit.to_dict()
doc = YourDocument(**dict_hit)
doc.property1 # you can access the property here
I know it is a bit awkward and annoying, it used to work with versions below 6.
I found a workaround, if you take the dictionary coming out from elasticsearch response you can then ask the document class to interpret it like the following.
query = MyDoc.search()
response = query.execute()
my_doc = MyDoc.from_es(response.hits.hits[0])
We were facing this situation. In our case, is was due to the index name in the Index subclass to configure Document indices. Our model looked more or les like this:
class MyDoc(Document):
my_field = Keyword()
class Index:
name = "my-doc-v1-*"
This way, when querying for documents in indexes that match that name (for example "my-doc-v1-2022-07"), hits are automatically instantianted as MyDoc objects.
Now we have started to generate 'v2' indices, named like "my-doc-v2--000001", and then hits were not being populated as MyDoc objects.
For that to happen, we had to change Index.name to my-doc-*. That way, documents from both 'v1' and 'v2' indices are always populated automatically by the library, since they match the Index.name expression.
What is wrong with this query?
const db = firebase.firestore()
const query = db.doc(this.props.user.uid).collection('statements').orderBy('uploadedOn', 'desc').limit(50)
I get the following error:

Since you haven't described what exactly you're trying to query, I'll just point out that all documents must be in a collection, without exception. So, if you say this:
db.doc(this.props.user.uid)
Firestore assumes that the string you're passing to doc() contains both the collection and document id separated by a slash. But this seems to be highly unlikely in your case. You need to determine which collection the uid is in, and use that first when you build the reference to the collection you want to query. Assuming that you do have a statements subcollection in the uid document, and that some other collection contains the uid document, you'll have to specify the full path like this:
db.collection('that-other-collection').doc(this.props.user.uid).collection('statements')
Of course, only you know the actual structure of your data.
If you want to get a collection of documents with querying, you don’t have to specify a document id. Below code should work in this case.
const query = db.collection('statements').orderBy('uploadedOn', 'desc').limit(50)
Or if you want to get the document, you can pass the document id to doc() method. In that case, the code should be.
const query = db.collection('statements').doc(this.props.user.uid)
For more details about querying firestorm data: https://firebase.google.com/docs/firestore/query-data/get-data?authuser=0
For others having this issue, make sure that no document reference has an empty string.
I had this issue when using a get method with uid input as below and forgot to check if uid is empty
private fun getFullRef(uid: String): CollectionReference {
return ref.document(uid).collection(FireContact.SUB_PATH)
}
I followed How do you copy a datetime field from the current document to a new document and I try something like this:
Cdoc.save();
Pdoc.copyItem(Cdoc.getDocument().getFirstItem("mytest1"));
getComponent('exampleDialog').show()
But I get a handling error message.
Thanks for your time!
Assuming Cdoc and Pdoc are defined as xp:dominoDocument data sources then you have to change your code to:
Cdoc.save();
Pdoc.getDocument().copyItem(Cdoc.getDocument().getFirstItem("mytest1"));
getComponent('exampleDialog').show()
So, you only need to add .getDocument() to Pdoc to get the Notes Document. Otherwise it fails and you get the error "Error calling method 'copyItem(lotus.domino.local.Item)' on an object of type 'NotesXspDocument'".
Keep in mind that you have to save Pdoc after copying item too if you want to show the copied item in your exampleDialog.
If you don't want to save document Pdoc at this point yet then you can copy the item on NotesXspDocument level with just:
Pdoc.replaceItemValue("mytest1", Cdoc.getItemValueDateTime("mytest1"));
getComponent('exampleDialog').show()
I do not often use "copyItem". You are not specifying if you are using NotesDocuments or NotesXspDocuments, so I will write a quick thing about both because they should be handled differently.
var currentDoc:NotesDocument = ....
var newDoc:NotesDocument= ...
newDoc.replaceItemValue("fldname", currentDoc.getItemValueDateTimeArray("fldname").elementAt(0))
if currentDoc is a NotesXspDocument, use the following
var currentDoc:NotesXspDocument = ...
var newDoc:NotesDocument=...
newDoc.replaceItemValue("fldname", currentDoc.getItemValueDateTime("fldname"))
Otherwise, you could continue trying with copyItem, I just lack experience with it.
EDIT
Just some things to add, remember that putting calling xspDoc.getDocument(true) will update the background document and this might be needed. Also, in the comments for that article you posted, they mentioned the possible need to put that document into another variable.
var docSource:NotesDocument = xspDoc.getDocument(true);
var docNew:NotesDocument = ...
docNew.copyItem(docSource.getItem("blah");
Also remember that copyItem is a function of NotesDocument and not NotesXspDocument.
I retrieve names from a group using formula, and put them in a field of type Names this way:
#Name([CN];NAME)
I want to manipulate this data in my code, but using Lotusscript. Can't find it at Google or Lotus Domino's Help. Is there a way I can handle this?
In LotusScript there is a class named "NotesName" to do such manipulations.
If there is a field named "NAME" in you document, then the code would look like:
Dim doc as NotesDocument
Dim nnName as NotesName
'Somehow get the document, using ws.CurrentDocument.document
'or db.UnprocessedDocments.GetFirstDocument, depends on your situation
Set nnName = New NotesName( doc.GetItemValue("NAME")(0) )
Whatyourlookingfor = nnName.Common
If NAME is a Multivalue then you would have to write a loop to get the common- name for every element in the array doc.GetItemValue("NAME")
The next time you have a question, check out the language cross reference in the help...
There it tells you, what the LotusScript- Pendant for #Name is.
Please try with below suggestion for getting list of person names from group.
First need to check the availability of searching group on names.nsf (All the groups are available on "($VIMGroups)" view.
if the group is available means you need to get the list of values from "Members" item
The members item have variant(list) values. So need to iterate the members for getting each value
Please refer the below sample code:
Set namesDb=session.GetDatabase(db.Server,"names.nsf")
Set groupVw=namesDb.GetView("($VIMGroups)")
Set groupDoc=groupvw.GetDocumentByKey("groupname")
persons= groupDoc.members
Forall person In persons
Msgbox person
End Forall
You can use the Evaluate method. It will return you the result of a Notes Formula:
Dim result as Variant
formula$ = "#Name([CN];NAME)"
result = Evaluate(formula$)
If the formula needs to be evaluated within the context of a document, you can pass that document as a second parameter to the method.

How do you copy a datetime field from the current document to a new document in Xpages, SSJS.
I am coping other fields like this
inheritDoc.appendItemValue("AbbreviatedCustomer",currentDocument.getValue("AbbreviatedCustomer"));
var item:NotesItem = inheritDoc.replaceItemValue("Author", n1); item.setNames(true);
item = inheritDoc.replaceItemValue("AuthorAccess", currentDocument.getValue("AuthorAccess")); item.setAuthors(true);
But I do not know how to copy a date field from the currentDocument to the inheritDoc.
Thanks
You don't have to care about data types copying fields (=Items) from one document to an other if you use
inheritDoc.copyItem(currentDocument.getDocument().getFirstItem("FieldName"))
or
inheritDoc.replaceItemValue("FieldName", currentDocument.getDocument().getFirstItem("FieldName"))
Fields in target document will have same data type, content and properties as in source document.
Try using toJavaDate():
inheritDoc.replaceItemValue("DateField", currentDocument.getValue("DateField").toJavaDate());
