Have I mentioned lately how awesome NSScreencast is? No? Worth the subscription. Check it out if you’re an iOS developer. Or even if you’re not and you want an example of how to do coding screencasts well.

Got tired of dead-end googling so I checked to see if @NSScreencast had covered what I was looking for. Of course he had, 4 years ago. Should have checked there first.

One 13-minute episode of @NSScreencast just paid for the yearly subscription fee in amount of time saved. Do it.

Seriously great stuff even for seasoned developers. I’ve learned a good amount from Ben’s videos.

You can really expand your development horizons in just a few minutes a week with NSScreencast.

Random PSA for iOS developers: @NSScreencast is a great resource, and worth every penny. It’s high quality, practical, and honest.

Can’t say enough good things about @NSScreencast There is gold in the Road Trip DJ Series.

I just reuppped my subscription to @NSScreencast. [An] indespensible resource if you’re into iOS or Mac Development.

Just finished @NSScreencast series on Modern CollectionViews. Strongly recommended. Programmatic UI, nicely structured code, easily approachable explanation style. 👌

There are 5 episodes with tag 'database'   Clear search
  • #371

    Server-side Swift with Vapor

    When you have a many-to-many relationship you typically rely on a join table, or what Vapor calls a Pivot table to relate the records together. In this episode we will create a relationship to allow an issue to have many tags, and also allow a tag to apply to many issues. We'll see how we can use Vapor's ModifiablePivot and Sibling types to make working with these relationships easier.

  • #365

    Server-side Swift with Vapor

    In the last 2 episodes we added some behavior to add automatically managed timestamp fields and some fairly complex logic to set up UUID primary keys the way we want. Now if we want to share those, or make them the default for our models, we currently have to copy & paste. In this episode we will refactor this logic into reusable protocols so that our work can be applied on any model we wish easily.

  • #364

    Server-side Swift with Vapor

    If you want to track when records are created and modified, you can add some fields to your model and Fluent will automatically manage them for you. You just have to take care to define your TimestampKey properties carefully so they match what Fluent expects.

  • #363

    Server-side Swift with Vapor

    In this episode we look at customizing the table and columns that Fluent creates for us. In addition to customizing our column data types, we'll also have to lean on an extension of Postgres to generate UUID values for us. We'll see how to customize some of the column constraints to suit our needs, and then create a development route to test it all out.

  • #362

    Server-side Swift with Vapor

    In this episode we set up a new Vapor application to use Postgresql as the database. We'll see how to configure FluentPostgreSQL, how to create and set up a connection to the database, and look at the defaults for PostgresSQLModel. We'll also discuss the pros and cons of using UUID primary keys over auto-incrementing integers.
