Hello,
An earlier post where I asked how to put mulitple tables's input
on one screen was answered with "accepts_nested_attributes_for" and
that seems to be what I need, but nothing appears on the screen for
the nested section. I've been using ideas from:
http://masonoise.wordpress.com/2010/07/23/rails-and-forms-using-accepts_nested_attributes_for/
http://railscasts.com/episodes/196-nested-model-form-part-1
http://asciicasts.com/episodes/196-nested-model-form-part-1
http://api.rubyonrails.org/classes/ActiveRecord/NestedAttributes/ClassMethods.html#method-i-accepts_nested_attributes_for
The following are my classes and a little code from the
"_form.html.erb" that I'm trying to make work:
class Person < ActiveRecord::Base
default_scope :order => 'last_name'
has_many :people_skills
accepts_nested_attributes_for :people_skills, :update_only =>
true, :allow_destroy => true
end
class PeopleSkill < ActiveRecord::Base
belongs_to :person
end
Also, there is a field in the people_skills table that is person_id,
which I remember reading in the "Agile.." book creates an FK there.
<%= form_for(@person) do |f| %>
<% if @person.errors.any? %>
# ... usual code concerning errors
<% end %>
<%= f.fields_for :people_skills do |builder| %>
<%= builder.label :skill, "Skill" %><br />
<%= builder.text_field :skill %>
</p>
<p>
<%= builder.label :competency, "Competency" %><br />
<%= builder.text_field :competency %>
</p>
<% end %>
<table>
<tr>
<td>
<div class="field">
<%= f.label :first_name %><br />
<%= f.text_field :first_name %>
</div>
</td>
<td>
AND THEN MANY OTHER ROWS AND FIELDS OF THIS TABLE.
The table data for the class "Person" shows up fine, but anything with
the "f.fields_for..." is invisible (but doesn't cause a syntax
error). What DOES cause an error is to put
"@Person.people_skills.build" in the "new" method of
people_controller.rb.
So, I'm looking for a way to have one screen which creates entries in
2 tables, linked by the PK-FK. What am I doing wrong or forgetting to
do?
Thanks,
Barney
