I have a user model that has a few different roles (say a client and
an agent) The agent has some extra relationships not found in a
client role (has_one :agent_profile, for instance)
I have an edit_profile action for an agent that has these nested
attributes in the form and the model
<% form_for @agent, :url => agent_path(@agent) do |form| %>
<%= form.label :name %>
<%= form.text_field :name %>
<% form.fields_for :agent_profile do |a_form| %>
<%= a_form.label :website, "Website Address:"%>
<%= a_form.text_field :website %>
<% end %>
<% end %>
If an agent_profile object isn't present however, when an agent edits
their profile, they get the:
ActionView::TemplateError (You have a nil object when you didn't
The error occurred while evaluating nil.new_record?
Is it common that I would have an after_initialize method such as:
self.build_agent_profile if self.role_name == "agent" && !
Seems a bit odd to me to do this for all relationships I have that
accept nested attributes, but I can't really think of a better way. I
also don't want to split the User model into two models because agents
and clients log in/sign up in the same way.
