This is a continuation from this thread: Passing a form as a local to a ajax rendered partial in Rails 5
I've searched extensively but haven't been able to find a working solution.
Relevant Controller (profits_controller.rb):
def new_tabs
@market = Market.order('mjsnumber').all.first
@profit = Profit.new
profit_types_markets_products
end
def fetch_market
@market = Market.where(:id => params[:market_id]).first
@form = params["form"]
respond_to do |format|
format.js { render layout: false}
end
end
Relevant View (new_tabs.html.erb):
<%= simple_form_for @profit, :remote => true do |form| %>
<% @markets.each_with_index do |market, i| %>
<%= link_to market.nick, fetch_market_path(:market_id => market.id, :form => form, profit: @profit), :remote=>'true', :id => 'navBtn' + market.id.to_s, :class => 'd-flex flex-grow-1 align-content-center text-center nav-item nav-link ' + active(i).to_s + profit_nav_font_color(market.color).to_s, "data-toggle" => "pill", "roll" => "tab", "style" => "background-color: " + market.color.to_s + ";", remote: true %>
<% end %>
<%= render :partial => 'edit_partial_form', locals: { market: @market, form: form, profit: @profit } %>
Relevant Partial (_edit_partial_form.html.erb):
<%= market.namae %>
<%= form.simple_fields_for :figures, :defaults => { :input_html => { :class => "floatTextBox" }}, remote: true do |figures_form| %>
<%= figures_form.input "[test]" %>
<% end %>
Relevant JS (fetch_market.js.erb):
$("#edit_partial_form").html("<%= escape_javascript(render partial: 'edit_partial_form', locals: { market: @market, form: @form, profit: @profit } ) %>");
Routes:
resources :profits do
resources :markets
resources :products
collection do
get 'new_by_product_type'
get 'new_tabs'
end
end
get "/fetch_market" => 'profits#fetch_market', as: 'fetch_market'
patch 'profits/:id/autosave', as: :autosave_profit, to: 'profits#autosave'
The partial renders correctly and the links seem to have the FormBuilder information. However, when I click the link, it shows the params in the controller but then encounters an error while loading the partial in the console:
ActionView::Template::Error (undefined local variable or method `form' for #<#<Class:0x00007fdbd6453648>:0x00007fdbd68db5f8>
Did you mean? fork):
1: $("#edit_partial_form").html("<%= escape_javascript(render partial: 'edit_partial_form', locals: { market: @market, form: form, profit: @profit } ) %>");
In my local environment, I receive the following full error message when clicking on the link for the second market in the list of generated markets:

I have removed the simple_form tag because even after changing it to a regular form during testing, the error persists with any method I call after field_for in the partial.
Thank you in advance.
EDIT:
I ultimately gave up and resorted to using the @profit variable to create a new form in the partial (not ideal, but functional). However, I am still curious if the original approach is achievable, so I will keep the question open.
