The TEMSDataSetResource is a very powerful component that enables rapid development of full document REST API’s for TDataSet using RAD Server. Using TEMSDataSetResource, along with traditional master detail relationship configurations, it is possible to expose, and automatically document data APIs via REST with no code at all.
In this article, I will cover sharing master detail data with no code, but also how to roll your own REST endpoint to cover more advanced detail with detail embedded calls.
In my previous article, I updated advise on getting started with Swagger UI, using the new WebFiles feature of RAD Server (from 10.3.2) as a way to view your documentation as you build your backend services API. This article will build upon the sample application created in that post.
Swagger UI (as previously discussed) is a great option for checking your documentation and working with the REST API. One of the challenges has always been CORS (Cross Origin Resource Sharing) that makes execution of the code a challenge when developing.
There are a few options now however. You can either work around this with browser plug-ins, (as seen before), enable CORS in the emsserver.ini under [Server.APICrossDomain], or embed swagger-ui inside your RAD Server instance.
In this video, I cover the latter option. You can watch how to get documentation up and running. The video shows how to configure your EMSServer.ini to share the external resource through RAD Server and also modify the downloaded files to automatically load up the API documentation directly from RAD Server.
WebFiles in RAD Server EMSServer.ini
The key to making this work is the WebFiles option that was added to RAD Studio in 10.3.2. This was primarily added to make it easier to serve out web content and support ExtJS for doing web client development under the Architect edition of RAD Studio, however, this also has the benefit of making other content available to share.
This last week, InterBase 2020 has been released bringing the awesome Tablespaces feature into play. This new feature enables splitting the database into groups of tables (a Tablespace) that can then be put onto different physical disks (to aid performance) but also enables partial backup of a database. I plan to cover this new feature, and some useful ideas about how to use them in an article in the coming weeks, but first, I want to address something a bit older in InterBase that I’ve not blogged about before. Why? Well recently, I was at a UK roadshow event, when content about InterBase 2020 was being previewed, and a developer said “This new stuff is cool, but what I really need is the ability to put data into a table temporarily in InterBase, and have it isolated from other transactions…. Other databases have it, when will InterBase get it?” Well, InterBase has had this for years!
Delphi Boot Camp add’s YouTube and Facebook streams to service demand.
Today was very exciting in the Embarcadero offices. Developers have been registering for Delphi Boot Camp in their thousands, with over 1000+ registering in the last weekend alone.
Having all this interested in Delphi is awesome, but also has raised quite a challenge for the team delivering Boot Camp due to physical viewing limitations in GoToWebinar. The decision was taken last week that we should add additional ways to stream this out to the 1000’s who were going to attend and Jim McKeeth started off looking into YouTube and Facebook streaming.
This morning, all attendees received an update email with the multiple streaming options included. During the first of the two live daily sessions we have seen huge numbers viewing on both Facebook and YouTube.
If you couldn’t get into GoToWebinar, either try the second session or watch the replay on YouTube later, keep an eye on community for the replays.
If you did watch the Boot Camp on YouTube, thank you to everyone who joined in with such fun discussions. (my personal favourite question was “So can I talk to Dolphins with this?” – I’ve seen some cool delphi apps, but that would be a nice hardware integration project) Please let us know what you think about these medias for the future.
You can also use the Starer Edition to qualify for upgrade pricing to RAD Studio or Delphi Pro / Enterprise or Architect editions. And with the mobile add on pack included along with the bonus pack, now is a great time to do that.
Visual LiveBindings is a technology that allows you to bind your data and objects (model) to the UI making. While LiveBindings is a key part of FireMonkey development, it is often overlooked by VCL developers.
A while ago I started a series of blogs on LiveBindings and how to use them with existing VCL applications. Covering seven blog posts, I looked at
Join Embarcadero experts and leading community MVP’s for 5 workshops from Monday 5th September to Friday 9th September.
Focusing on getting stared and using the FMX framework to create cross platform ready code, Delphi Boot Camp is a great way to learn new skills and ask leading experts direct questions on application development.
Introduction to Delphi: The IDE and Your First App
Getting to Know the Delphi Language
Building Effective User Interfaces with FireMonkey
The final part of the Boot Camp is the programming book! Delphi is the home to modern Object Pascal programming and you can get up to speed with the modern Delphi / Object Pascal language with the help of Marco Cantu’s awesome handbook.
