I am new to CUBA and so far am impressed with the functionality.
Right now, I have been provided a set of REST URL’s to manage an external application.
I would like to build screens and the CRUD functionality that would access the provided API’s just like using entities locally in CUBA. No entities are accessible from external app. Only URLs.
Is there any built-in functionality to handle there kind of requirements? What is the best way to use CUBA to cater these kind of requirement?
Thanks
Hi,
In order to display and edit your data in standard CUBA UI, you have to map the data to entities. There are different ways to do it:
Create a service working with your external API and mapping data to non-persistent entities. Then use a custom datasource in your screens that loads entities from the service. Saving of changes has to be implemented by invoking separate methods of your service. This approach is illustrated here: GitHub - aleksey-stukalov/custom-datasource: This example illustrates how to create and use custom collection datasource in the CUBA Platform
Create a custom data store for your external API. It will allow you to integrate with the external system more naturally and to implement saving changes from entities back to the external system. See this project for details: GitHub - cuba-labs/custom-data-store: Example of implementing custom DataStore and using non-persistent (transient) entities

Hello Konstantin,
I’m attempting to do something similar and cloned your project mentioned above at https://github.com/aleksey-stukalov/custom-datasource. However, I receive the following error when the gradle wrapper is being configured initially:
Build file '/Users/adam/StudioProjects/custom-datasource/build.gradle' line: 91
A problem occurred evaluating root project 'custom-datasource'.
> Could not find method leftShift() for arguments [build_8isbv3p809bunnngtiwfihcub$_run_closure4$_closure19@403ebc52] on task ':app-core:cleanConf' of type org.gradle.api.DefaultTask.
I’m wondering if there is an updated version of this project, or a new way of achieving the results with importing data from an external API.
Thanks in advance!
Adam
