I’m trying to do belongs_to on my magnets (posts) but it’s also null, cast_assoc is not doing anything. I’m pretty sure I’m just doing something wrong My magnets (posts) has belongs_to :user, Magnify.Coherence.User And when I create a new magnet (post) def changeset(magnet, attrs) do magnet …

Then, yes, you do need to preload :magnets: def get_flux!(id) do Flux |> Repo.get!(id) |> Repo.preload(:magnets) end so that you have access to them in the template <%= @flux.description %> <%= Enum.map(@flux.magnets, fn magnet -> %> <p><%= magnet.name %></p> <% end) %>

That code is wrong, getting a syntax error
