Question

I’m getting this odd error, as if SimpleForm isn’t even installed:

undefined method `simple_form_for'

SimpleForm IS in my gemfile and I’ve installed:

Using simple_form (2.0.2)

I’m running on the Pow server, so it’s restarting every time.

#events_controller.rb
class admin::EventsController < ApplicationController
  def new
    @event = Event.new
  end

#Event.rb
class Event
  include Mongoid::Document
  field :summary
  field :start_date
  field :end_date
end

#new.html.haml
= simple_form_for [:admin, @event] do |f|
  = f.input :summary
  = f.input :start_date
  = f.input :end_date

Any ideas why it seems like SimpleForm isn’t even installed?

Answer 1

Did you run the generator after you installed the gem? In your console you need to run this:

rails generate simple_form:install
