Validate behaving strangely in a nested form.

[Luis]

Hi all,

this form will not display the nested part when it fails validation.

What is really throwing me in a loop is that if eliminate one of the ":include_blank => true"

it works.

I have tried changing them to text_field and it fails also.

Thanks for you help in advance.

class Elig < ActiveRecord::Base

  belongs_to :patient

  validates_presence_of :contract, :effective

end

class Patient < ActiveRecord::Base

     has_one :elig

    validates_presence_of :dob, :name, :last

    validates :name, uniqueness: {scope: [:name, :last, :dob]}

    validates_associated :elig

end

= form_for(@patient) do |f|

  - if @patient.errors.any?

      %h2

        = pluralize(@patient.errors.count, "error")

        prohibited this patient from being saved:

      %ul

        - @patient.errors.full_messages.each do |msg|

          %li= msg

  .field

    =f.label :Name

    = f.text_field :name

    /more text_field/

    /---------------/

    %br

    =f.fields_for :elig do |e|

      %br

      = e.label :Efective

      = e.date_select :effective, start_year: Date.today.year,order: [:day,:month, :year], :include_blank => true

      %br

      = e.label       :Termination

      = e.date_select :termination, start_year: Date.today.year,order: [:day,:month, :year], :include_blank => true

      %br

      = e.label :Renewal

      = e.date_select :renewal, start_year: Date.today.year,order: [:day,:month, :year], :include_blank => true

      %br

      = e.label       :Contract

      = e.text_field :contract

      %br

  .actions

    = f.submit

I forgot to post this line for the Patient class.

    accepts_nested_attributes_for :elig, reject_if: :all_blank, allow_destroy: false

I fix the problem.

It is very annoying when this types of mistakes do not generate an error. 

(It is almost as bad as my day of c programming chasing a memory leak.

 dgb to the rescue.)

class PatientsController < ApplicationController
def create
    @patient = Patient.new(patient_params)
    @elig =@patient.build_elig  patient_params["elig_attributes"] #***** I was missing this line
    debugger
    respond_to do |format|
      if @patient.save
        format.html { redirect_to @patient, notice: 'Patient was successfully created.' }
        format.json { render :show, status: :created, location: @patient }
      else
        format.html { render :new }
        format.json { render json: @patient.errors, status: :unprocessable_entity }
      end
    end
  end

this looks like a very interesting project, I've been having some issues with assigning associations thru a form on an related type of app, getting a form that crates an polymorphic association when a provider creates an order and such. would you be up for an email chat on the topic by chance? I've a demo application up here: https://warm-river-76092.herokuapp.com thanks for posting the solution to your issue!
