The bool Comment on CircleAuthorizationToBlogPost was dead code:
never read or written by any caller in src/, no UI exposure, no
behavioural semantics. The wire DTO (CircleAuthorization in
Yavsc.Abstract) doesn't carry it, no reader consumes it, and the
PostIt client builds its payload without it.
What changes:
- src/Yavsc.Server/Models/Access/CircleAuthorizationToBlogPost.cs:
remove the property.
- src/Yavsc.Blogs.Tests/BlogAclApiTests.cs: drop 'Comment = true'
from the existing test payload and trim the now-inaccurate XML
doc comment ('CircleId + BlogPostId + Comment' -> 'CircleId +
BlogPostId'). Also adds a new [Fact] pinning the prod bug
reported on 2026-08-21 (HTTP 500 'BlogPostId is unknown' when
PostIt POSTs the bare { circleId } shape). That test stays red:
the real fix for the 500 is in PostIt (payload needs blogPostId)
+ on the wire DTO + server-side validation, and lives in a
follow-up commit.
Migration:
- src/Yavsc.Org/Migrations/20260820232152_DropCommentFromCircleAuthorizationToBlogPost
drops the boolean 'Comment' column on CircleAuthorizationToBlogPost.
The generated scaffold also wanted to drop three 'ClientId1'
shadow FK columns on ClientScopes / ClientRedirectUris /
ClientGrantTypes (from leftover HasOne<Client>() overrides in
ApplicationDbContext.OnModelCreating); those were removed from
the .cs to keep the migration scoped to this fix. Cleaning up the
shadow property declarations themselves is left as a separate
task.
The ModelSnapshot still reflects the shadow 'ClientId1' columns
intentionally: they exist in the prod database today (all NULL),
and EF will rescaffold a drop migration for them on the next
'migrations add' regardless. No data loss.
System.Text.Json cannot materialise an interface without a
polymorphic converter. Until this commit, BlogPostDto.Author
was typed as the abstract interface IApplicationUser, which
crashed the "load posts" call in PostIt whenever the server
returned a post with a populated Author object (the common
case — GET /api/BlogApi).
Fix:
* Introduce a minimum-viable wire DTO BlogPostAuthorDto in
Yavsc.Abstract.Blogspot (record: Id, UserName, Avatar).
These are the only fields the client UI actually needs;
the server-side ApplicationUser navigation is preserved
for permission checks and authorisation.
* Change IBlogPost.Author and BlogPostDto.Author from
IApplicationUser to BlogPostAuthorDto? (interface change,
breaking). The EF entity BlogPost keeps its full
ApplicationUser navigation property and exposes
IBlogPost.Author via an explicit interface implementation
that projects to BlogPostAuthorDto on demand (so EF can
still lazy-load the navigation without forcing an eager
join on every read).
* Restore the using directive that was accidentally removed
when the BlogPostDto property was rewritten (needed for
ICircleAuthorization in GetACL()).
Regression coverage (the missing test Paul flagged):
* Add BlogPostAuthorDtoTests in PostIt.Tests with four
scenarios that exercise the wire shape on the client side:
- A BlogPostDto JSON with a populated Author round-trips
through JsonSerializer without throwing and the three
fields (Id, UserName, Avatar) survive intact.
- A BlogPostDto JSON with explicit "author": null
deserialises with Author == null.
- A BlogPostDto JSON without any Author field at all
deserialises with Author == null (forward compat).
- The serialised shape of BlogPostAuthorDto uses camelCase
property names (matching the server's Web defaults), so
the field names on the wire don't drift without a test
catching it.
Tests: 55/55 PostIt.Tests (+4 new), 24/24 Yavsc.Blogs.Tests,
44/44 Yavsc.Org.Tests. No regressions.
Side note: yavsc.sln picks up Yavsc.Api.Client (added by
'feat/postit-acl' in 1.0.7 but never registered in the
solution file until now — probably auto-added by a recent
'dotnet build' that discovered the .csproj).
