Hey,
I’ve successfully followed this tutorial (with slight modifications) to add and remove embeds_many
form fields in inputs_for
with LiveView.
Now I’d like to preprocess the embedded records so that they’re sorted by a custom function and the fields marked to be deleted are hidden (I also want to replace the “delete” checkbox with a button). The problem is that I don’t know how I can manipulate the form and pass the result to inputs_for
.
As for hiding to-be-deleted items, I’ve already tried several things like the following but nothing works (apparently because LiveView doesn’t see the updated values):
<%= f = form_for ... %>
...
<%= for item <- inputs_for(f, :items) do %>
<%= if not Map.has_key?(item, :changes) || is_nil(item.changes.delete) do %>
...
<% end %>
<% end %>
</form>
Thanks in advance!
