Last lesson: viewers' requests - Dojo Course
UPDATE (2017-11-22): Dojo Course 2 is released with new, updated videos! In the last lesson of the Dojo Course, we look into a few topics asked by you! Let's see Facebook Suite, Antispam and C# scripting! Facebook suite: installation and usage of the several widgets that bring Facebook features into your website! Antispam: Orchard offers a few solutions out of the box to fight spam! They are: JavaScriptAntiSpamPart, ReCaptcha, Akismet and Typepad. C# scripting: how to add C# code on the frontend which can be integrated with other features, e.g. content validation and Workflows! Thank you for your attention in this 3 months and have a very good year filled with awesome Orchard stuff! Remember: if you have any questions don't hesitate to ask them by creating a new issue in the Orchard issue tracker with the "discussion" label. Make sure to prefix your thread's title with "Dojo Course - "! We keep an eye on these issues. Also follow us on Twitter to get notified about the latest Dojo Course news, including when a new tutorial is posted. Do you have some feedback about the course? Please send it in.

Useful and interesting services to enhance your features - Dojo Course
UPDATE (2017-11-22): Dojo Course 2 is released with new, updated videos! Dojo Course is almost over, so we move on to the spicy parts of the Orchard API that enable you to do really interesting things! An in-depth recap on what we did so far in our PersonList feature. Content querying: using Orchard's LINQ-like API, the IContentManager service to retreive content pieces (including usage and optimization points). How to integrate your features into the administration menu? Running code periodically using background tasks. Running code at a specified time using scheduled tasks. Creating system-wide event handlers to be able to communicate with other pieces of logic in an even more loosely tied way. And a little addition to migrations: you can implement an Uninstall method in your Migrations class to add some logic which will run when your feature is being removed from a system (hopefully nobody will use it ;) ). Stay tuned for the (really) last part of the Dojo Course before Christmas! Remember: if you have any questions don't hesitate to ask them by creating a new issue in the Orchard issue tracker with the "discussion" label. Make sure to prefix your thread's title with "Dojo Course - "! We keep an eye on these issues.

Client-side development and a little more of the Orchard API - Dojo Course
UPDATE (2017-11-22): Dojo Course 2 is released with new, updated videos! This week on Dojo Course we move on to some frontend-related development and see how to use static resources and other important features provided by MVC and Orchard. After that we return to the server-side to learn something new. How to add your static resources to your templates? Script/Style.Include/Require. Some userful helpers to customize your templates. Dynamically creating and displaying a shape. How to protect yourself against cross-site request forgery attacks? Posting forms and using the MVC model binder to check if the entered data in our editor is valid or not. Some debugging and bug hunting (restarting the system solved the mystery). And now, for something completely different: file management in Orchard using the IStorageProvider. Remember: if you have any questions don't hesitate to ask them by creating a new issue in the Orchard issue tracker with the "discussion" label. Make sure to prefix your thread's title with "Dojo Course - "! We keep an eye on these issues.

End of Dojo Course nearing! What do you want to learn a bit more about?
UPDATE (2017-11-22): Dojo Course 2 is released with new, updated videos! The last two tutorials of Dojo Course will soon come - they are already recorded. This brings us to the project works! There are many of you who enrolled to Dojo Course: it's almost time for you to submit the project work if you'd like to get a certificate of accomplishment! To help you (and so you can also watch the last tutorials of course) we've extended the deadline of the submissions: you now have time until 20th December to submit your work. Remember that you can still request us to review your code as explained in the FAQ. Remember: we can only grade your project and thus issue you a certificate of accomplishment if you submit your work! Also, don't forget about the short presentational video! And now something else: on the last lesson we'll mostly hear the students of the university course present their work; however, we'll have some spare time, about half an hour. If you'd like to learn about something that we haven't covered in the course or would like to see an explanation more in-depth about a topic now it's time for you to chime in: submit your idea in a comment here! We'll evaluate the proposals and pick what is the best for that half an hour (maybe a bit more), then we'll publish this very last tutorial later. Time is short: please submit your ideas in the next 24 hours, at least until Wednesday noon, CET!

Diving into the Orchard API - Dojo Course
UPDATE (2017-11-22): Dojo Course 2 is released with new, updated videos! This week on Dojo Course we dive into the Orchard API, use some of the build-in services and extending the capabilities of our module to make it even better! Using LazyField<T> to load data lazily so they are only loaded when we really need them. Using Work<T> to load dependencies lazily so they are only resolved when we really need them. Applying the [Admin] attribute for admin-related Getting to know an other Orchard service: IAuthorizer. Creating our own permissions by implementing the IPermissionProvider. Using the ContentManager so we can finally work with content items! Generating ad-hoc shapes and matching them to an actual template. Implementing the IResourceManifestProvider interface for managing static resources. Remember: if you have any questions don't hesitate to ask them by creating a new issue in the Orchard issue tracker with the "discussion" label. Make sure to prefix your thread's title with "Dojo Course - "! We keep an eye on these issues. Also follow us on Twitter to get notified about the latest Dojo Course news, including when a new tutorial is posted. Do you have some feedback about the course? Please send it in. Haven't you enrolled yet? Why not do it some time in the near future like right now?

Content Part development continued - Dojo Course
UPDATE (2017-11-22): Dojo Course 2 is released with new, updated videos! This week on Dojo Course we are giving life to our content part by adding several Orchard-y code pieces to it, though the result is far from being Frankenstein-like. While doing that, we also discover some interesting and useful pieces of the Orchard API. Creating a migration for our Contents feature. Difference between ContentPartRecord and ContentPartVersionRecord: versioning content parts. Making your content part attachable to content types (on the Admin UI). Creating a content type using migrations and attaching parts to it. Creating a handler for our content part to do some plumbing (e.g. StorageFilter). Creating a driver for our content part to cover server-side part of the the user interface interaction. How displaying a shape works, what is DisplayType? Shape templates (also editors) and using Placement. Using InfosetPart to store a part's data in the content item's XML infoset document. This eliminates content part record lazy loading, providing a significant performance gain. The importance of driver shape factories. How to make your content part support importing and exporting? Remember: if you have any questions don't hesitate to ask them by creating a new issue in the Orchard issue tracker with the "discussion" label. Make sure to prefix your thread's title with "Dojo Course - "! We keep an eye on these issues.

Forum favourites: multi-node Orchard, community features and low-level data access
Forum topics from the Orchard discussion board that we found interesting: Running Orchard on two nodes: this is a tricky thing but in this discussion there some good tips Community features in Orchard: a lot of built-in and third-party modules bring "social" functionality to Orchard. You won't be able to just install Contrib.Facebook but there are some decent fundamentals. A tale of database table locking, transactions and low-level data access in Orchard: sometimes you just have to bury deeper.

Data storage and content part development - Dojo Course
UPDATE (2017-11-22): Dojo Course 2 is released with new, updated videos! How to upgrade my table schema? How to store and retrieve records from my tables? How do I upgrade from using a plain set of records to using a content part? This week on Dojo Course we are moving on to uncover the mysteries of content parts. Making modifications to your Migrations classes: how to use the update methods. Quick recap on Dependency Injection and creating a service class to handle our records. Benedek has problems with typing when he knows he's being watched (actually, Zoltán as well) :). Difference between requiring a single and list of dependencies. How to (and how not to) use IRepository<T> to store and retreive records. Based on what we learned about records, we are starting to develop our first content part. Dividing your module into features (subset of functionalities) and declaring dependencies between them. Assigning pieces of code to specific features using the OrchardFeature attribute. Remember: if you have any questions don't hesitate to ask them by creating a new issue in the Orchard issue tracker with the "discussion" label. Make sure to prefix your thread's title with "Dojo Course - "! We keep an eye on these issues.

Module development continued - Dojo Course
UPDATE (2017-11-22): Dojo Course 2 is released with new, updated videos! The fifth lesson of Dojo Course will teach you more about module development: how to build your own logic that is able to store data and what are the basic services that aid you in your work. A quick recap of the last lesson: command line scaffolding, creating a controller and a view, dependency injection Using the IWorkContextAccessor and exploring the WorkContext (and the HttpContext inside) object: content parts and items everywhere! Attaching the debugger to the IIS Express worker process How to display CLRExceptions in VS to see the exceptions that otherwise would be swallowed somewhere in the stack: Ctrl+D,E and check the "Thrown" checkbox Using the INotifier service Property injection: Localizer and Logger How to properly structure your T-strings to make them bulletproof agains translations: String.Format Routing in MVC and defining custom parameters Basic data storage: creating a record class (which is the OO representation of our data) and a migration class to define the table schema Looking at the DB after the migration to see what our code did there Remember: if you have any questions don't hesitate to ask them by creating a new issue in the Orchard issue tracker with the "discussion" label. Make sure to prefix your thread's title with "Dojo Course - "! We keep an eye on these issues.

Have you started your Dojo Course project yet?
UPDATE (2017-11-22): Dojo Course 2 is released with new, updated videos! If yes, why not? :-) Seriously, it's about time: we're deeply in module development now but there's no reason not to start working on your theme already: you know everything about theme development! (OK, maybe not everything but every essential information to create your theme.) Remember: the earlier you start making use of our offer to review your code (see the FAQ) the more reviews we can give you. If you have questions, go on and ask them in the Orchard discussion board (and if you have read the FAQ you also know how to make sure that if nobody else, we'll help you there). Also, Dojo Course news are announced on Lombiq's Twitter feed too, so follow us to keep up to date.
