I hve a relationship like this in my model:
Student
has_one :student_fail
StudentFail
belongs_to :student_fail_state
belongs_to :student
StudentFailState
has_many :students, :through => :student_fail
has_many :student_fails
In terms of the controller, what would be the best way to update
attributes to the student_fails table?
Here's the view stuff:
resources_form_helper.rb:
def render_form_collection_field(form, name, label = nil, size = nil)
render_form_field(form, name, label) do
params = yield
form.collection_select name, params[:collection],
params[:value_method],params[:text_method], {}, {:size => size}
end
end
def render_form_field(form, name, label=nil)
label ||= name.to_s.gsub(/_id$/, '').gsub('_', ' ')
label_class = "error" if error_fields.include?(name.to_sym)
<<END_HTML
<li>
#{form.label name, label, :class => label_class}
<div>#{yield}</div>
</li>
END_HTML
end
view:
[ render_form_collection_field(f, :student_fail_state_id, 'level') { {
:collection => StudentFailState.true, :value_method => :id, :text_method
=> :name} } ]
#:student_fail_state_id doesn't currently working because it's not in
the student table.
Any suggestions on how to update other tables from a dropdown menu?
Thanks.
