@idi527 this is great, thanks appreciate it
I’m getting - function Magnify.Magnets.create_flux/1 is undefined or private. Did you mean one of:
Called with 1 arguments
%{"description" => "fff", "magnet_id" => ["2", "3"], "title" => "aff"}
I have the following in my templates
<%= multiple_select f, :magnet_id, @magnets, class: "form-control" %>
and the controller
magnets = Magnets.list_magnets(params) |> Enum.map(&{&1.description, &1.id})
I’m thinking that is were the issue is ?
Ok I know what the issue, is it’s the calling the create which only has case Magnets.create_flux(flux_params) do
just need to figure how to get magent_ids as that is inside flux_params
"Parameters: %{"_csrf_token" => "VxwHMmkfLwMhPhxuHRVcfn0DGTgfEAAA1lDzBRjRLGIVyqsL67MTOA==", "_utf8" => "✓", "flux" => %{"description" => "aaa", "magnet_id" => ["2"], "title" => "aaaa"}}
"
Maybe
magnet_ids = params["magnet_id"] || []
create_flux(params, magnet_ids)
But then you might need to check that the user actually has access to the magnet ids in params.
Well the create is like so
def create(conn, %{"flux" => flux_params}) do
IO.inspect flux_params
case Magnets.create_flux(flux_params) do
{:ok, flux} ->
conn
|> put_flash(:info, "Flux created successfully.")
|> redirect(to: flux_path(conn, :show, flux))
{:error, %Ecto.Changeset{} = changeset} ->
render(conn, "new.html", changeset: changeset)
end
end
and flux_params had the keys
"Parameters: %{"_csrf_token" => "VxwHMmkfLwMhPhxuHRVcfn0DGTgfEAAA1lDzBRjRLGIVyqsL67MTOA==", "_utf8" => "✓", "flux" => %{"description" => "aaa", "magnet_id" => ["2"], "title" => "aaaa"}}
def create(conn, %{"flux" => flux_params}) do
magnet_ids = flux_params["magnet_id"] || []
case Magnets.create_flux(flux_params, magnet_ids) do
{:ok, flux} ->
conn
|> put_flash(:info, "Flux created successfully.")
|> redirect(to: flux_path(conn, :show, flux))
{:error, %Ecto.Changeset{} = changeset} ->
render(conn, "new.html", changeset: changeset)
end
end
I did that got
Postgrex expected an integer in -9223372036854775808..9223372036854775807, got “1”. Please make sure the value you are passing matches the definition in your table or in your query or convert the value accordingly.
Which is working but the many to many is the wrong format
what I have
many_to_many :magnets, Magnify.Magnets.Magnet, join_through: “magnets_fluxes”
def create(conn, %{"flux" => flux_params}) do
magnet_ids = Enum.map(flux_params["magnet_id"] || [], fn magnet_id ->
String.to_integer(magnet_id)
end)
case Magnets.create_flux(flux_params, magnet_ids) do
{:ok, flux} ->
conn
|> put_flash(:info, "Flux created successfully.")
|> redirect(to: flux_path(conn, :show, flux))
{:error, %Ecto.Changeset{} = changeset} ->
render(conn, "new.html", changeset: changeset)
end
end
Well It’s getting there I now got
schema Magnify.Magnets.Flux does not have association :magents
Which I have no idea what is going on I added the many to many ?
Sweet it’s working, holy ****. I have so much more to learn. It’s failing
def show(conn, %{"id" => id}) do
flux = Magnets.get_flux!(id)
render(conn, "show.html", flux: flux)
end
flux_controller.ex:35: MagnifyWeb.FluxController.show/2
which is this part flux = Magnets.get_flux!(id)
