Context

Form is created through command

$ rails g scaffold Cotizacion

Template installed from link

Objective and problem

The idea is to integrate the form new , which creates a new quote to the bootstrap template.

Understanding that I am trying to use a form that corresponds to another controller.

The structure of the project is as follows. You are trying to call the _form.html.erb form of the quotes view, from the index.html.erb file corresponding to the view < em> creatives . Both views occupy different controllers (can that be done?)

Invocation to form from index.html.erb :

<%= render :partial =>'cotizaciones/form' , cotizacion: @cotizacion%>
<%= render 'navbar' %>
<%= render 'header' %>
<%= render 'services' %>
<%= render 'portfolio' %>
<%= render 'call_to_action' %>
<%= render 'contact' %>

The message displayed by the application when lifting the page is the following:

undefined local variable or method 'quote' for < #: 0x007fcae29cb080 > Did you mean? quote_url

Extracted source (around line # 1):

      <%= form_with(model: cotizacion, local: true) do |form| %>
      <%= form_with(model: cotizacion, local: true) do |form| %>
      <% if cotizacion.errors.any? %>
      <div id="error_explanation">
      <h2><%= pluralize(cotizacion.errors.count, "error") %> prohibited 
       this cotizacion from being saved:</h2>

The problem is that you are not recognizing the variable cotizacion because you are performing the assignment incorrectly: to pass variables to a partial you must use the attribute locals .

To solve it simply assign the variable cotizacion using the attribute locals :

<%= render partial: 'cotizaciones/form', locals: { cotizacion: @cotizacion } %>

Alternatively, as an alternative option, you can eliminate the use of the attribute partial and so you can pass the variable as you were doing:

<%= render 'cotizaciones/form', cotizacion: @cotizacion %>

The two options generate the same result, so I recommend using the second one (it is shorter), however use the one that is the most simple / intuitive and consistent in its use throughout your application.
