How do I permit date selector attributes in Rails and Formtastic

Question

Latest

I have switched to Simple form. No problem with permitting date attributes there.

Recent attempts

I have put a demo repository on Github illustrating the problem:

This one uses formtastic and displays my problem with:

Unpermitted parameters: date_of_receipt(1i), date_of_receipt(2i), date_of_receipt(3i), date_of_receipt(i)

https://github.com/bigos/permit_date_selector/commit/9f142b79c51e71dca35c988125a2912b83b91972

This one doesn't use formtastic and works fine;

https://github.com/bigos/permit_date_selector/commit/4c53b934ac5cd3f04241bf462e7b677ef5d28335

Initial post

When I try to submit my form I get this message

Unpermitted parameters: date_of_receipt(i)

I have :date_of_receipt in the list of permitted parameters.

My form input selecting the date looks as follows:

<%= f.input :date_of_receipt, as: :date_select %>

Should I give up on formtastic and go back to standard forms?

I've created a fresh Rails app (using Rails 4.1.5 and Formtastic 2.3.1) to try to replicate, and I can't, so I'm closing. Here's what I had:

# Migration
class CreatePosts < ActiveRecord::Migration
  def change
    create_table :posts do |t|
      t.string :title
      t.string :body
      t.datetime :published_at

      t.timestamps
    end
  end
end

# Model
class Post < ActiveRecord::Base
end

# Controller
class PostsController < ApplicationController
 def new
    @post = Post.new
  end

  def create
    @post = Post.new(post_params)
    if @post.save
      redirect_to @post
    else
      render :new
    end
  end

  def show
    @post = Post.find(params[:id])
  end

  protected

  def post_params
    params[:post].permit(:title, :body, :published_at)
  end
end

# View
<%= semantic_form_for @post do |f| %>
  <%= f.inputs do %>
    <%= f.input :title %>
    <%= f.input :body %>
    <%= f.input :published_at %>
  <% end %>
  <%= f.actions do %>
    <%= f.action :submit %>
  <% end %>
<% end %>

By simply permitting :published_at , I was able to successfully save a Post into the database with the time I had selected. Here's the development.log:

There's no extra trickery required, this is how you do it :)

When you inspect the element on the page, you will see three different elements for date_select.

model[date_of_receipt(1i)], model[date_of_receipt(2i)], model[date_of_receipt(3i)]

So you will have to permit

date_of_receipt(1i), date_of_receipt(2i), date_of_receipt(3i) 

in your controller
