Creating new object for associated model - ruby-on-rails

Question

So I've been at this a while and have tried a bunch of different methods. Essentially I have an over-arching property model and an associated deed model. From the properties#show view I have it displaying all associated deeds. I have a button in my property view that displays a modal (using AJAX) to create a deed associated to said model. All the steps work (even 'edit' and 'update' using AJAX from the properties view) except when trying to save the new deed I get an error message:
This form contains 1 error. Property must exist
I've tried passing the #properties.id through in different ways and I just can't seem to get it. I'll list all the relevant info I have and if more is needed just let me know.
Property Model
class Property < ApplicationRecord
has_many :deeds, dependent: :destroy
accepts_nested_attributes_for :deeds
end
Deeds Model
class Deed < ApplicationRecord
belongs_to :property
accepts_nested_attributes_for :property
end
Deeds Controller (Included edit and update actions)
def new
#deeds = Deed.new
#deeds.build_property
respond_to do |format|
format.html { render 'new'}
format.js
end
end
def create
#properties = Property.find(params[:deed][:property_id])
#deeds = #properties.deeds.new(deed_params)
if #deeds.save
flash[:success] = "Deed created successfully!"
respond_to do |format|
format.html { redirect_to deeds_path }
format.js
end
else
render 'new'
end
end
def edit
#deeds = Deed.find(params[:id])
respond_to do |format|
format.html { #deeds.save }
format.js
end
end
def update
#deeds = Deed.find(params[:id])
#properties = Property.find(#deeds.property.id)
#deeds.update_attributes(deed_params)
respond_to do |format|
format.html { redirect_to deeds_path }
format.js
end
end
private
def deed_params
params.require(:deed).permit(:property_id, :deed_number, :deed_context, :consideration, :recorded_date, :grantor, :grantee, :trustee)
end
new deeds link from properties#show view
<%= link_to fa_icon("plus", text: "Add Deed"), new_property_deed_path(#properties.id), remote: true, class: "btn btn-primary btn-large btn-ouline pull-right", locals: { property_id: #properties } %>
new.js.erb
$('#deeds-modal').modal("show");
$('#deeds-modal').html('<%= j render partial: "deeds/deeds_modal", locals: { property_id: #properties } %>');
_deeds_modal.html.erb partial Form
<div class="modal-body">
<%= bootstrap_form_for(#deeds, layout: :horizontal, remote: true) do |f| %>
<%= render 'shared/error_messages', object: f.object %>
<%= f.hidden_field :property_id, value: property_id %>
<%= f.text_field :deed_number, class: 'form-control' %>
<%= f.text_field :deed_context, class: 'form-control' %>
<%= f.text_field :consideration, class: 'form-control' %>

<% end %>
<% end %>

So as you can see I've tried to pass through a local variable from the new link -> new.js.erb -> deeds modal form but I can't seem to pull the property_id into the new deeds object.
Is this even the correct approach for what I'm trying to do or am I just missing something? Hope this wasn't too long of a read and that I provided enough info... lol.
*Upon writing this post I clicked through some of the 'similar questions' on SO, which is where I got the #properties = Property.find(params[:deed][:property_id]) line from but I still get ActiveRecord::RecordNotFound (Couldn't find Property with 'id'=): upon submission. Also, thank you to anyone who takes the time to read this.

Answer 1

This should be you new action
def new
#deeds = Deed.new
#deeds.build_property
#properties = Property.find_by_id(params[:property_id]) # add this line
respond_to do |format|
format.html { render 'new'}
format.js
end
end
Update:
If you are not using the associated property anywhere else, you don't need to pass the locals and I don't suggest hidden_field as it can be easily modified, alternately you can do..
def new
#deeds = Property.find_by_id(params[:property_id]).deeds.new # add this line
#deeds.build_property
respond_to do |format|
format.html { render 'new'}
format.js
end
end

Answer 2

As the error says Property must exist, so, your intention is to print the property_id for a new record, but for some reason that's not happening.
As that value goes from your form_for directly to create a new "deed", then in must be setted on it, you do it, but you don't check if it's printing something or not, and it get's you a nil value that's not allowed because of the relationship between Deeds and Properties.
When you send the form, you can see the value is empty:
"deed"=>{"property_id"=>""}
How do you define which property_id must a new record have? You can create a variable within your new method and set an object to print within your form_for, it'll give you a value to proceed with a new record.
When you make a request to the new method you pass through the params the value for property_id:
Processing by DeedsController#new as JS
Parameters: {"property_id"=>"99"}
So I suppose you could use it instead setting a local variable which hasn't been initialized, maybe you can try with:
<%= f.hidden_field :property_id, value: params[:property_id] %>
