Я пытаюсь использовать вложенные атрибуты simple_form, как предложено в https://github.com/plataformatec/simple_form/wiki/Nested-Models
Дело в том, что при рендеринге формы я просто вижу кнопку отправки, но не поле ввода. Что я делаю не так?
_form.html.erb
<%= simple_form_for [:admin, @incident] do |f| %>
<%= f.error_notification %>
<%= f.simple_fields_for :comments do |builder| %>
<%= builder.input :info, label: "Informe de seguimiento" %>
<% end %>
<div class="form-actions">
<%= f.submit "Enviar", class: "btn btn-primary" %>
</div>
<% end %>
incidents_controller.rb
class Admin::IncidentsController < ApplicationController
before_action :set_incident, only: [:show, :edit, :update]
def index
@incidents = Incident.all
end
def show
end
def new
@incident = Incident.new
@incident.comments.build
end
def edit
end
def update
respond_to do |format|
if @incident.update(incident_params)
format.html { redirect_to @incident, notice: 'Incidencia actualizada actualizada con éxito.' }
format.json { render :show, status: :ok, location: @incident }
else
format.html { render :edit }
format.json { render json: @incident.errors, status: :unprocessable_entity }
end
end
end

@incident = Incident.find(params[:id])
end
def incident_params
params.require(:incident).permit(:info, :subject, :status, comments_attributes: [:info])
end
end
