I have two models, Dog and Owner, and I want their names to be the same, and would be redundant if I asked to fill out the fields twice (once for the dog and another time for the owner). I'm wondering if there's a simpler way to update the two databases with one input.
<h1>Create a new Dog:</h1>
<%= form_for(@dog) do |f|%>
<div>
<%= f.label :name%>
<%= f.text_field :name%>
</div><br>
<div>
<%= f.label :breed%>
<%= f.text_field :breed%>
</div><br>
<div>
<%= f.label :age%>
<%= f.text_field :age%>
</div><br>
<div>
<h3>create a new owner:</h3>
<%= f.fields_for :owner, Owner.new do |owner_attributes|%>
<%= owner_attributes.label :name, "Owner Name:" %>
<%= owner_attributes.text_field :name %>
<% end %>
</div>
<%= f.submit %>
<% end %>
First of all, not sure why you want to keep the name of the owner and the dog same.
However, there can be many ways to achieve what you want:
So you no longer need: <%= owner_attributes.label :name, "Owner Name:" %>
OR you no longer need:
<div>
<%= f.label :name%>
<%= f.text_field :name%>
</div><br>
And in the Owner/Dog model, you can pass the name of the dog/owner in a callback - maybe after_initialize or before_save or before_validation depending on your validation requirements.
class Dog
belongs_to :owner
before_validation :set_name
private
def set_name
self.name = owner&.name
end
end
onblur
event. I would prefer the first approach since it's simpler and more secure than only JS solution to maintain database consistency
