Kaffy v0.9.1 has just been released. This is a community release since it was mainly developed by the community (issues and PRs submitted). Thank you all for contributing.
Please note that if you use/depend on Kaffy for your app, you should stick to v0.9.x since v0.10 will not be backwards compatible.
The main thing for v0.9.1 was keeping compatibility with the latest phoenix releases.
It also fixes a few issues submitted by the community.
Hi @aesmail
It is not clear to me (and I can’t find it on docs) how to use has_one / belongs_to relation on the index view.
Nearest thing I found was:
category_id: %{
value: fn p -> get_category!(p.category_id).name end,
filters: Enum.map(list_categories(), fn c -> {c.name, c.id} end)
},
What is get_category?
Are you doing a query per row?
What’s the best way to preload the relations on Kaffy?
Thanks!
get_category!() is a custom function not related to Kaffy.
You can actually customize the query to preload the wanted relations. This will modify the query that Kaffy runs for the index view, which means it will only be executed once (not per row).
You can do something like this:
# the admin module
defmodule MyApp.Context.SchemaAdmin do
def custom_index_query(_conn, _schema, query) do
from(r in query, preload: [:my_relations])
end
def index(_) do
[
title: nil,
belongs_to_field_id: %{name: "Hits", value: fn p -> p.belongs_to_field.something end},
date: %{name: "Date Added", value: fn p -> p.inserted_at end}
]
end
end
I hope this makes things a bit clearer. Let me know if you have any more questions

Thanks!
The plan for v0.10 is to be released very soon (August or September).
The focus will be on extensibility.

@aesmail
First of all, thank you for a spectacular tool!
I had recently one issue with Kaffy in the umbrella app. The Extension module was not loaded on the server start, so my css and js files were not added to the DOM. However, when server was already running, and I made any change in the Extension file, then the css and js were added to the DOM on website refresh.
After debugging the code, I found that function_exported?(ext, :stylesheets, 1) from lib/kaffy/utils.ex was giving false. Adding Code.ensure_loaded(ext) solved my issue.
I’ve created Pull Request and added more details there.
