I'm just working on a rather dated project on App Engine that still uses the old 'db' model format instead of 'ndb'.
What would be the simplest way to serialize a 'db' query into JSON?
For example:
sections = Section.all() >>> JSON
All of the methods that I found from a google search use the to_list method of 'ndb' models.
Thanks!!!
A quick read of the docs (you have done that ?) turns up to_dict https://cloud.google.com/appengine/docs/python/datastore/functions?hl=en#to_dict which allows you to transform a model entity to a dictionary. Dictionaries can be transformed to JSON (unless they have Decimal values and a few other types, but I am sure you can work around that.). Then just iterate over the query result, producing a list of dicts, which you can json.dump(thelist)
However if you have a lot of entities you will have to take some additional steps, but you can read the docs to work out that.

I have been using React/Leaflet to create a choropleth map that can color any country on the map. What I am trying to do is to develop a save/load function that saves the colored countries and later be able to import it from the database. When this object is saved and loaded, it can bring back the exact same countries that were colored. I have been using firebase/firestore but I haven't been getting any luck.
This is how my object of map data looks like
Is Firestore the right database to do it? Or should I approach another database? I need a database that can store multiple objects in the picture above.
If you can convert that file into a JSON of a size smaller than 1MB, which is the Firestore Document size limit, it is possible. In the case you are proposing I would have the following structure, from the information you shared but fell free to adapt it as you see fit:
Map Collection
field1
...
fieldN
CountriesOptions Subcollection
optionObject: {}
Where each object is a separate document in the CountriesOptions subcollection converted to JSON using JSON.stringify(obj).
For more information on how to structure your Firestore with subcollections you can check this link to the documentation.
I am looking to create a feature whereby a User can download any available documents related to the item from a tab on the PDP.
So far I have created a custom record called Documentation (customrecord_documentation) containing the following fields:
Related item : custrecord_documentation_related_item
Type : custrecord_documentation_type
Document : custrecord_documentation_document
Description : custrecord_documentation_description
Related Item ID : custrecord_documentation_related_item_id
The functionality works fine on the backend of NetSuite where I can assign documents to an Inventory item. The stumbling block is trying to fetch the data to the front end of the SCA webstore.
Any help on the above would be much appreciated.
I've come at this a number of ways.
One way is to create a Suitelet that returns JSON of the document names and urls. The urls can be the real Netsuite urls or they can be the urls of your suitelet where you set up the suitelet to return the doc when accessed with action=doc&id=_docid_ query params.
Add a target <div id="relatedDocs"></div> to the item_details.tpl
In your ItemDetailsView's init_Plugins add
$.getJSON('app/site/hosting/scriptlet.nl...?action=availabledoc').
then(function(data){
var asHtml = format(data); //however you like
$("#relatedDocs").html(asHtml);
});
You can also go the whole module route. If you created a third party module DocsView then you would add DocsView as a child view to ItemDetailsView.
That's a little more involved so try the option above first to see if it fits your needs. The nice thing is you can just about ignore Backbone with this approach. You can make this a little more portable by using a service.ss instead of the suitelet. You can create your own ssp app for the function so you don't have to deal with SCAs url structure.
It's been a while, but you should be able to access the JSON data from within the related Backbone View class. From there, within the return context, output the value you're wanting to the PDP. Hopefully you're extending the original class and not overwriting / altering the core code :P.
The model associated with the PDP should hold all the JSON data you're looking for. Model.get('...') sort of syntax.
I'd recommend against Suitelets for this, as that's extra execution time, and is a bit slower.
I'm sure you know, but you need to set the documents to be available as public as well.
Hope this helps, thanks.
I am experimenting IBM watsons' Discovery API to get data insights. I want to query using multiple filters. I am using python to accomplish the task. I have tried this for now, but this is not working.
qopts = {'filter':[{'enriched_text.entities.text:Recurrent Neural
Networks,Machine Learning classifiers'}]}
my_query = discovery.query(env_id, coll_id, qopts)
with only single entity : 'recurrent Neural Networks' through the discovery UI and through my python query, I get 3 documents from the collection.
but with two entities, 'Recurrent Neural Networks,Machine Learning classifiers', in the UI I get 2 documents but through my code, I get 2 documents.
Below is then right format which works for me. with multiple concept and keyword filters, I get a total of 2 search results, which match with the UI query
qopts = {'filter':{'enriched_text.concepts.text:"Neural network",enriched_text.keywords.text:"Neural Network",enriched_text.keywords.text:"generative conversational models"'}}
with only entity I get 3 match results
qopts = {'filter':{'enriched_text.concepts.text:"Neural network"'}}
in this example I am querying the documents with concept 'Neural network' , keywords 'Neural Network' and 'generative conversational models'
Inside Watson discovery documentation, inside the UI you'll use (according to the documentation):
But obviously, without the ! operator inside the second text.
and I think inside your code you need to use , between the values.
Not sure because I don't use the enriched_text.entities.textinside my filter, just the Strings.
One possible reference for another example to test:
filter=field1:some value,field2:another value
Official reference documentation: here.
I am building a RememberMe Component using the AuthComponent and would like to get the BaseAuthenticate::$settings data (userModel and fields) data out of the XxxxAuthenticate object so I can know what model and fields I should be dealing with, but I can't seem to figure out how to get that data back out.
Any suggestions?
Basically I need something with the same functionality as Auth::getModel( ) or Auth::$userModel from Cake 1.X.
Cake- 2.0.3
Auth::$userModel still exists in 2.0. However, you probably have to access it via the instantied object rather than statically:
$modelData = $this->Auth->userModel;
If this isn't set, then it defaults to User.
You can then get the model by looking at the first array key that is returned:
$modelName = key($modelData[0]);
I can't seem to do this. The list that the app engine datastore viewer does not contain Text as an option. I had to change my fields because some of my values were too long for String, but now I can't retroactively fix my old entries.
To change the property type used by the old entities, you need to manually update each of them.
This can be easily and efficiently accomplished using the mapper API. This guide explains how to use this API.

You don't have to fix your old entries. The old ones should work as is, and the new ones just won't be indexed.
