Using non associated models data in a form

Question

Is it possible to access another models attributes without having associations? For example I want to create a Prediciton record via a form using the fixture models attributes

<%= form_for @prediction do |f| %>
<%= f.fields_for :fixtures, @fixtures do |builder| %>

<%= builder.text_field :home_team %> VS <%= builder.text_field :away_team %><%= f.text_field :home_score %><%= f.text_field :away_score %><br>

<% end %>
<% end %>

how would i get the attributes of the fixture model without associating the two models?

Thanks

It's much easier if you create the association. If you are not going to create the association, such in the case where you are using a view not backed by a model and your are pulling in and modifying various models from it (assumption I am making) you can do something similar to this:

First make sure you setup routes.rb for whichever methods you are planning to use against the various models.

predictions model

@fixtures = Fixture.all

or specific attributes example

@fixtures = Fixture.select([:home_team, :away_team, :home_score, :away_score]).all

The above is if you are updating another models records. You will also need to modify the create method.

Your view you would want to change from a form_for to a form_tag:

form_tag('/predictions') do

Hopefully this gets you going in the right direction.
