How to use Bigquery streaming insertall on Ruby Rails - ruby

EDIT: Fixed - for ruby use "insert_all" instead of "insertAll" like the api specifies. The api for ruby needs updating.
Im using v 0.6.4 of the google-api-client gem and trying to create a streaming insert, but keep getting the following error:
google_bigquery.rb:233:in undefined method `insertAll' for #<Google::APIClient::Resource:0xcbc974 NAME:tabledata> (NoMethodError)
My code is as follows:
def streaming_insert_data_in_table(table, dataset=DATASET)
body = {"rows"=>[
{"json"=> {"person_id"=>1, "name"=>"john"}},
{"json"=> {"person_id"=>2, "name"=>"doe"}},
]}
result = #client.execute(
:api_method=> #bigquery.tabledata.insert_all,
:parameters=> {
:projectId=> #project_id.to_s,
:datasetId=> dataset,
:tableId=>table},
:body_object=>body,
)
puts result.body
end
Could someone tell me if the insetAll has been created for the google-api-client gem? I have tried 'insert' as that is what table, dataset etc use and get the same error as well.. I can however run tabledata.list perfectly fine.. I've tried digging throught the gem source code and didn't get anywhere with that.
Is the body object that I created correct or do I need to alter it?
Any help is much appreciated.
Thanks in advance and have a great day.

Ok. So fixed it and updated the code in the question. For ruby: the method is called "insert_all". Also note that the table & schema must be created BEFORE the insert_all. This id different when compared to the the "jobs.insert" method which will create the table if it doesn't exist

How to Fix Document Not Found errors with find

I have a collection of Person, stored in a legacy mongodb server (2.4) and accessed with the mongoid gem via the ruby mongodb driver.
If I perform a
Person.where(email: 'some.existing.email#server.tld').first
I get a result (let's assume I store the id in a variable called "the_very_same_id_obtained_above")
If I perform a
Person.find(the_very_same_id_obtained_above)
I got a
Mongoid::Errors::DocumentNotFound
exception
If I use the javascript syntax to perform the query, the result is found
Person.where("this._id == #{the_very_same_id_obtained_above}").first # this works!
I'm currently trying to migrate the data to a newever version. Currently mongodbrestore-ing on amazon documentdb to make tests (mongodb 3.6 compatible) and the issue remains.
One thing I noticed is that those object ids are peculiar:
5ce24b1169902e72c9739ff6 this works anyway
59de48f53137ec054b000004 this requires the trick
The small number of zeroes toward the end of the id seems to be highly correlated with the problem (I have no idea of the reason).
That's the default:
# Raise an error when performing a #find and the document is not found.
# (default: true)
raise_not_found_error: true
Source: https://docs.mongodb.com/mongoid/current/tutorials/mongoid-configuration/#anatomy-of-a-mongoid-config
If this doesn't answer your question, it's very likely the find method is overridden somewhere in your code!

How do I call the evernote struct object to report all notes inside a notebook?

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.

Rally API using Ruby: How do I reference the testcase method (Automated/Manual)?

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.

How to get the journal/notes for a Redmine issue in Ruby?

I am using the redmine_client (0.0.1) gem to lookup issues in Redmine but get an error when I do something like this:
puts issue.journals.inspect # error - undefined method `journals' for #
I am following this example: https://gist.github.com/552610
Any idea what might be the problem? All the other fields work fine except for journal.
Journals is an association to an Array of Journal objects. I don't know if I've added Journal support to that gem yet (I don't use it much anymore). Try forking the gem and adding a new journal.rb class like issue.rb.

How do you print JSON from the mongdb ruby driver?

When I do a find query from the mongodb JavaScript console, I get a beautiful JSON response. However, when I do a find with the ruby driver, it stores the JSON as some Ruby object. How do I convert this back to JSON? Or, better yet, how do I just get the JSON without doing the extra conversions?
I got it working. I was using ruby-1.9.1-p378 with rvm. I removed that. Now, I'm using the system ruby-1.8.7-p174 that came with the SnowLeopard install DVD. But, I was still getting an error with the to_json method except this time it was saying, stack level too deep. I did:
require 'json/pure'
instead of
require 'json'
Then, I changed the code to look something like this:
http://github.com/banker/mongulator/blob/master/mongulator.rb#L53
Here's the relevant part of the code:
cursor = persons.find(
{"loc" => {"$near" => [params[:lat].to_f, params[:lng].to_f]}},
{:limit => 20})
content_type "application/json"
JSON.pretty_generate(cursor.to_a)
The complete file is here:
http://github.com/acani/acani-sinatra/blob/master/acani.rb
And, it worked, even with pretty json like the facebook graph api gives you. To return the JSON all on one line, just do something like:
cursor.to_a.to_json
The JSON Code you get on the javascript console is also converted. It's not the native output of MongoDB, the Native format is BSON. To Get JSON on the javascript console it must be converted. In Ruby you should be able to do the same thing with the .to_json instance method of your Object.
now you can do cursor.find.to_a.inspect
