Hello Devs
A little background to my question:
I have a live form where I want to pass a jsonb
field and cast to a schema. When doing it with simple bigint
type for example it can be easily done:
<%= for player <- @players do %>
<form phx-submit="add_points">
<%= number_input :player_points, :points, placeholder: "Something" %>
</form>
<% end %>
def handle_event("add_points", %{"player_id" => %{"player_id" => player_id}, "player_points" => %{"points" => points_for_player}}, socket) do
(...)
Points.assign_player_points(points_for_player)
{:noreply, socket}
end
Here I have a number input which gets a variable named player_points
and I can Repo update a schema with it in a context:
|> Player.changeset(%{points: points_for_player})
|> Repo.update()
However, doing it with a jsonb doesn’t seem that easy. I managed to create this:
<%= number_input :points1_for_first_player, :points1_for_first_player, name: "score[game1][points1_for_first_player]", class: "form-control" %>
<%= number_input :points1_for_second_player, :points1_for_second_player, name: "score[game1][points1_for_second_player]", class: "form-control" %>
which means this:
"score" => %{
"game1" => %{
"points1_for_first_player" => "11",
"points1_for_second_player" => "5"
},
}
}
So far so good, but I receive in the live view points1_for_first_player
& points1_for_second_player
variables.
And my question is: how should that kind of variable be Repo updated to the jsonb field :score
?
(
field :score, :map
)
If something is unclear, please, comment.
Best Regards
