Question

I have a simple Rails 3 application that has a number of models. A simple overview of the models I’m having trouble with is:

client model

has_many :animals

animal model

belongs_to :client

What I would to be able to do is show a list of other animals that are owned by the same client.

Something like this:

<% @client.animals.each do |animal| %>
  <%= animal.AnimalName %>
<% end %>

As this is within the Animal controller, my example code won’t work. Any pointers would be appreciated.

Update

To clarify, if I have the following records:

Danny (Client)
Cat (animal owned by Danny)
Dog (animal owned by Danny)
Rabbit (animal owned by Danny)

and I then went to the show view of the Dog’s record, I would like a list that would show all animals that Danny owned. E.g.

Cat
Dog
Rabbit

Ideally excluding the currently viewed animal (in this case dog).

I have tried the following but it doesn’t seem to work:

<% @client.animals.each do |client| %>
  <%= @client.animal.AnimalName %>
<% end %>

Answer 1

If I understand you correctly you have @animal and want to show all the animals owned by the owner of @animal. This can be done like this:

<% @animal.client.animals.each do |animal| %>
  <%= animal.AnimalName %>
<% end %>

Update:

You can just add a .where onto @animal.client.animals:

@animal.client.animals.where('id != ?', @animal.id).each ...

It’s not such a good idea to do this in a view. So I would add an instance method to my Animal model:

def other_animals_with_same_owner
  client.animals.where('id != ?', id)
end

With this you can do:

@animal.other_animals_with_same_owner.each ...
