Rails: Fields_for without scope?
Is there a way to use fields_for on a form without having a scope?
For example:
<% fields_for "user[]" do |x|
<%= x.text_field :name %>
<% end %>
Without loading a custom model into memory?
I was working using the [user] [] [name] territory, but I would like to store it in the ERB.

I think the answer is "no", because they form_for
and fields_for
will try to determine the default value of this instance variable.
However, I think that if you want to reduce memory usage when loading this model, you can try creating a mock model to return nil values and instantiate the object instead.

Is there any specific reason why you need to use form_for? It is really meant to be used with an instance of an object object.
Alternatively, why don't you just use regular form helper tags. You can define it like this:
<%form_tag :my_form do %>
<%= text_field_tag :foo, :bar %>
<%end%>
You can check the documentation for a look at the steps to see how it all works.
