Dlango

I really like Django, but I'm not in love with Python. It's nice. D is better.

If you would like to talk about the project, join the official Dlang Discord and ping me (._carter) in either #webdev or #programming.

Constraints for the sake of constraints

Personally I won't be using AI assistance for code generation or linting, with perhaps one exception--security. In my view, not augmenting security audits with powerful tools is foolish.

I want to refrain from using AI assistance for code generation and linting because I enjoy programming. I enjoy not knowing and I enjoy figuring it out on my own. I acknowledge that this will make the project take longer. I'm fine with that.

Quickstart

• build dlangoadmin project.
• place dlango-admin/.exe in your path.
• create new project: dlango-admin createproject --name=projectname
• As of writing, the generated project does not start a webserver or provide a convenient way for you to add routes (June 25).
  • I will fix this tomorrow night.

Usage

Dlango uses code-generated database schemas.

struct User {
    /// bakes in orm functionality + id field.
    mixin Model!User;

    string username;
    string email;
    string password;
    long createdAt;
}

Once you run makemigrations and migrate, the schema is in place. Migrations are stored in source/migrations/ along with a manifest.

Querying

User("retrac", "retrac@gmail.com", "password").save();

auto filtered = User.objects.filter(
  Q("email__iexact", "RETRAC@gmail.com"),
  Q("username__exact", "retrac")
);

foreach (user; filtered) {
	writeln(user.username, " ", user.email, " ", user.ID);
}
// Output: retrac retrac@gmail.com 1

Field lookups

As you may have noticed, field lookups are currently very similar to Django field lookups.

• exact: Field must exactly match the value.
• iexact: Case-insensitive exact match (value is lowercased before comparison).
• contains: Field contains the value (uses LIKE '%value%').
• gt: Greater than (>).
• gte: Greater than or equal (>=).
• lt: Less than (<).
• lte: Less than or equal (<=).
• startswith: Field starts with the value (uses LIKE 'value%').
• endswith: Field ends with the value (uses LIKE '%value').
• in: Field value must be in a given list (uses IN).
• isnull: Field must be NULL (uses IS NULL).

Compiler

Only promise hope is that this will compile with ldc2. DMD has never treated me right.
