I have a protobuf object in ruby, and it has a map as one parameter. How can I create a Google::Protobuf::Map? If I try to enter a standard hash table, I get an Expected Map instance error.
--EDIT--
Found the answer here: https://developers.google.com/protocol-buffers/docs/reference/ruby-generated#map-fields, if anyone needs that.

I am trying to get some key values from features in extent but I am unable to.
I tried to look up ID [feature.getId()] which works totally fine, see here:
If I try feature.get('id') it's undefined for some reason. (And it's undefined for every key I am trying to get by name)
I tried feature.getKeys() and it's returning geometry,info,index,popup.
I stored every info I need under info key.
I tried to get data in console and I can see that a point has 'id' key, and I am unable to get it with feature.get('id')
Does anyone know what am I doing wrong?
I had to access values with Object.values method.
Object.values(Object.values(feature.get("info"))[0][2])[1]
I try to invoke a flow through Braid. The flow takes a List<UniqueIdentifier> object as input parameter. When invoking the flow I get the following error:
error: -32000: java.util.LinkedHashMap cannot be cast to net.corda.core.contracts.UniqueIdentifier
Can someone help with this?
This is a deserialisation error of Braid. It might get fixed in a future version. A workaround at the moment is to use Array objects instead of List objects in Corda.
Useful functions are:
List.toTypedArray()
and
Array.asList()
I am working through the ruby evernote-thrift API and sandbox.
I am experiencing some issues interpreting the docs; I am trying to retrieve the subject line from all the notes inside a particular notebook.
To get the name of the notebook I call
notebooks = noteStore.listNotebooks(authToken) and then run .each on notebooks. According to the docs there is a struct object called noteList but I can’t figure out how to use it.
this is the link to the docs area I am trying to leverage http://www.rubydoc.info/gems/evernote-thrift/Evernote/EDAM/NoteStore/NoteList#struct_fields-instance_method
my attempt, is as follows, but its not returning anything. unfortunately im not familiar with structs at all.
notebooks = noteStore.listNotebooks(authToken)
notebooks.each do |notebook|
next if notebook.name != 'First Notebook'
notes = notebook.noteList
noteList.each do |note|
puts note
end
end
i am getting a no method error... which makese sense because its a struct I just dont know how to leverage it...
undefined method `noteList' for <Evernote::EDAM::Type::Notebook:0x007fb2041683f8> (NoMethodError)
The generated docs for our Ruby SDK are confusing (sorry!), but I find the general docs to be much clearer: https://dev.evernote.com/doc/reference/.
As you can see in https://dev.evernote.com/doc/reference/Types.html#Struct_Notebook, the Notebook object does not have an attribute called noteList. There is a struct called NoteList, but that was what the removed NoteStore.findNotes returned.
The procedure for getting the titles/subjects of the notes in a notebook is to get the Notebook (which you have done), then pass the notebook's guid into NoteStore.findNotesMetadata (https://dev.evernote.com/doc/reference/NoteStore.html#Fn_NoteStore_findNotesMetadata). This returns a NotesMetadataList which has a notes attribute which is a list of NoteMetadata. This struct has metadata like title and GUID but not the body. If you want the full information, you would pass the GUID into NoteStore.getNote (https://dev.evernote.com/doc/reference/NoteStore.html#Fn_NoteStore_getNote).
That API is one of the least Ruby things I've ever seen. You have my condolences for trying to trudge through that :)
From the API docs, all I'm seeing that hangs off of that Evernote::EDAM::Type::Notebook class are #struct_fields and #validate, as far as instance methods go. Perhaps that struct_fields has what you're looking for?
If that doesn't lead you anywhere, I'd suggest doing using something like Pry to help you troubleshoot the error. I'd put a binding.pry statement on the second line and then explore the notebooks objects from there.
I've installed titan-0.5.0-hadoop2 with hbase and elasticsearch support
I've loaded the graph with
g = TitanFactory.open('conf/titan-hbase-es.properties')
==>titangraph[hbase:[127.0.0.1]]
and a then I loaded the test application
GraphOfTheGodsFactory.load(g)
Now when I'm trying to create a new index key with:
g.makeKey('userId').dataType(String.class).indexed(Vertex.class).unique().make()
and I got this error:
No signature of method: groovy.lang.MissingMethodException.makeKey() is applicable for argument types: () values: []
Possible solutions: every(), any()
Display stack trace? [yN]
Can someone help me with this ?
when I want to see the indexed keys I see this
g.getIndexedKeys(Vertex.class)
==>reason
==>age
==>name
==>place
I'm not completely following what you are trying to do. It appears that you loaded Graph of the Gods to g and then you want to add userId as a new property to the schema. If that's right, then i think your syntax is wrong, given the Titan 0.5 API. The method for managing the schema is very different from previous versions. Changes to the schema are performed through the ManagementSystem interface which you can get an instance of through:
mgmt = g.getManagementSystem()
The syntax for adding a property then looks something like:
birthDate = mgmt.makePropertyKey('birthDate').dataType(Long.class).cardinality(Cardinality.SINGLE).make()
mgmt.commit()
Note that g.getIndexKeys(Class) is not the appropriate way to get schema information either. You should use the ManagementSystem for that too.
Please see the documentation here for more information.
I am using Ruby to work with the Rally API. I am trying to reference the testcase method. The method being Manual or Automated, but I always get an error. I am using Ruby, so I don’t know if method is a reserved word in Ruby, or what is happening. Could you please let me know how to reference the test case method?
I am able to do:
testcase.objective
testcase.priority
etc.
But I can’t do
testcase.method
I always get this error.
‘method’: wrong number of arguments (0 for 1) (ArgumentError)
Are you using rally_rest_api or rally_api?
If you are using rally_rest_api - Charles is correct. try testcase.elements[:method]
(fieldname downcased and underscored as a symbol)
If you are using rally_api - http://rubygems.org/gems/rally_api -
Getting fields can just be:
testcase["FieldName"]
Hope that helps.
You just need to capitalize the names when trying to access built-in fields (i.e. fields that are not custom). I came across this problem myself and using tc.Method instead of tc.method fixed it.
The reason this error shows up can be seen in the docs for Object#method which, as you've likely figured out by now, causes your code to call the method method instead of access the field named method.
