Can't generate a form with form helpers - ruby

Question

I'm trying to generate a form with an html.erb file, that looks something like this:
<form class="edit-booking" method="post" action="/users/<%= current_user.id %>/accounts/1/bookings/new" data-remote="true">
<header><h1>Edit booking</h1></header>
<input class="booking-name" name="booking[name]" placeholder="Name of the user" type="text" />
<fieldset class="booking-list">
<h2>Booking details</h2>
<ul>
<li>
<input name="booking[name]" type="text" value="Unit name" disabled/>
<input name="booking[check_in]" type="date" value="" />
<input name="booking[check_out]" type="date" value="" />
</li>
</ul>
</fieldset>
<input name="submit" type="submit" value="Save" />
</form>
an I have this ruby code:
<%= form_for [current_user] do |f| %>
<header>
<h1>Edit booking</h1>
</header>
<%= field_set_tag 'Booking details' do %>
<%= f.fields_for :bookings do |booking_form| %>
<%= booking_form.text_field :name, placeholder: "Name" %>
<%= booking_form.text_field :check_in, placeholder: "Check-in" %>
<%= booking_form.text_field :check_out, placeholder: "Check-out" %>
<% end %>
<% end %>
<%= f.submit "Save" %>
<% end %>
But what happens is, it doesn't render anything on the browser even though in the chrome dev tool it shows a form tag.
EDIT:
The html generated is as following:
<form accept-charset="UTF-8" action="/users/1/accounts/1" class="edit_account" id="edit_account_1" method="post"><div style="margin:0;padding:0;display:inline"><input name="utf8" type="hidden" value="✓"><input name="_method" type="hidden" value="patch"><input name="authenticity_token" type="hidden" value="fzA+hkk3o+itJOI0UDj9F01DuI+A5+zgQ1EVGlwrPww="></div>
<header>
<h1>Edit booking</h1>
</header>
<fieldset><legend>Booking details</legend>
<input id="account_bookings_name" name="account[bookings][name]" placeholder="Name" type="text">
<input id="account_bookings_check_in" name="account[bookings][check_in]" placeholder="Check-in" type="text">
<input id="account_bookings_check_out" name="account[bookings][check_out]" placeholder="Check-out" type="text">
</fieldset>
<input name="commit" type="submit" value="Save">
</form>
My Account model:
class Account < ActiveRecord::Base
belongs_to :user
has_many :products
has_many :bookings
accepts_nested_attributes_for :bookings
accepts_nested_attributes_for :products
end

Answer 1

In your model add:
#Account model
accepts_nested_attributes_for :bookings
Also, should your current_user be an account?
