This is my delete button that I use:
@doc """
This must not be inside of another form!
"""
def delete_button(path), do: delete_button(path, :raised, [])
def delete_button(path, btn_type) when is_atom(btn_type), do: delete_button(path, btn_type, [])
def delete_button(path, opts) when is_list(opts), do: delete_button(path, :raised, opts)
def delete_button(path, btn_type, opts) do
{form, opts} = Keyword.pop(opts, :form, [])
{form_class, form} = Keyword.pop(form, :class, "")
form = Enum.map(form, fn {k, v} -> ~E{ <%= dasherize(k) %>="<%= v %>"} end)
opts = opts ++ [do: "Delete"]
opts = Keyword.put(opts, :class, "btn--red #{opts[:class]}")
~E"""
<form action="<%= path %>" class="link <%= form_class %>" method="post"<%= form %>>
<input name="_method" type="hidden" value="delete">
<input name="_csrf_token" type="hidden" value="<%= get_csrf_token() %>">
<%= button(:submit, btn_type, opts) %>
</form>
"""
end
And if I want an ‘are you sure’ kind of thing then I instead just put it inside a pure CSS collapsible element that I use here with the title of it as something like ‘Dangerous options’ or whatever and the delete button inside of it, so it first has to be expanded then the delete button can be clicked or so.
