I have the following resources defined:
resources :buildings do
resources :buildings_regular_hours
end
My models are are follows:
class Building < ApplicationRecord
has_many :building_regular_hours
def to_s
name
end
end
class BuildingsRegularHours < ApplicationRecord
belongs_to :building
end
I am attempting to create a form to allow for creating and editing of BuildingRegularHours. Currently the form I have will display on #edit, but will not display on #new.
new.html.erb:
<%= render 'form', buildings_regular_hour: @buildings_regular_hour, building: @building %>
edit.html.erb:
<h1>Editing Buildings Regular Hour</h1>
<%= render 'form', buildings_regular_hour: @buildings_regular_hour, building: @building %>
<%= link_to 'Back', building_buildings_regular_hour_path(@building) %>
_form.html.erb:
<%= form_for([building,buildings_regular_hour]) do |f| %>
<% if buildings_regular_hour.errors.any? %>
<div id="error_explanation">
<h2><%= pluralize(buildings_regular_hour.errors.count, "error") %> prohibited this buildings_regular_hour from being saved:</h2>
<ul>
<% buildings_regular_hour.errors.full_messages.each do |message| %>
<li><%= message %></li>
<% end %>
</ul>
</div>
<% end %>
<div class="field">
<%= f.label :building_id %>
<%= f.text_field :building_id %>
</div>
<div class="field">
<%= f.label :start_date %>
<%= f.date_select :start_date %>
</div>
<div class="field">
<%= f.label :end_date %>
<%= f.date_select :end_date %>
</div>
<div class="actions">
<%= f.submit %>
</div>
<% end %>

Having added a BuildingRegularHours via console, I attempted the #edit action, and it works just fine, displaying the form as expected. However, when I attempt the #new action, I receive the following error:

I note that I have properly nested the resources in the form_for tag, that both @building and @building_regular_hour are set by the controller, and that I am calling the form in exactly the same way for both #edit and #new. This is all I've had to do previously to make nested resources work, so I'm at a bit of a loss as what to do next.
Please note I have not attempted to make the form work yet - I know there is work to be done there. I just am trying to get #new to display the form.
You need to correct the association
class Building < ApplicationRecord
has_many :buildings_regular_hours
def to_s
name
end
end
class BuildingsRegularHour < ApplicationRecord
belongs_to :building
end
Your model name should always be singular BuildingsRegularHour or it will create issues with routes and associations
