Getting error (undefined method) for form_with - html

Question

I have _form.html.erb. and on the first line of code, it is throwing this error:
undefined method `assessments_path' for #ActionView::Base:0x00000000229750
Did you mean? asset_path
couple of points:
in routes 'poweruser' is a namespace
in models assessment.rb is
not folder poweruser (as I plan to use it for other pages that anyone can access not just powerusers).
Any ideas what I am missing?
Here is the code:
<%= form_with(model: [#assessment], local: true) do |form| %>
<%= render "shared/error_messages", resource: form.object %>
<div class="form-group">
<%= form.label :name %>
<%= form.text_field :name, class: "form-control" %>
</div>
<% end %>
Here is the controller
module Powerusers
class AssessmentsController < ApplicationController
before_action :authenticate_user!
# before_action :set_assessment
# before_action :set_assessment, only: [:set_assessment, :show, :edit, :update, :destroy]
# Overwrite any of the RESTful controller actions to implement custom behavior
# For example, you may want to send an email after a foo is updated.
#
# def update
# super
# send_foo_updated_email(requested_resource)
# end
def index
#pagy, #assessments = pagy(Assessment.sort_by_params(params[:sort], sort_direction))
# We explicitly load the records to avoid triggering multiple DB calls in the views when checking if records exist and iterating over them.
# Calling #assessments.any? in the view will use the loaded records to check existence instead of making an extra DB call.
#assessments.load
end
# GET /assessments/new
def new
#assessment = Assessment.new
#assessment.assessment_sections.new
end
here is the assessment.rb (not it is not in a sub-folder poweruser)
class Assessment < ApplicationRecord
belongs_to :company
has_many :assessment_sections, inverse_of: :assessment
has_many :questions, through: :assessment_sections
accepts_nested_attributes_for :assessment_sections, reject_if: :all_blank,
allow_destroy: true
accepts_nested_attributes_for :questions, reject_if: :all_blank,
allow_destroy: true
end
Here is the routes
# PowerUser
authenticated :user, lambda { |u| u.admin? } do
namespace :powerusers do
resources :assessments do
resources :assessment_sections do
resources :questions
end
end
end
end

Answer 1

As you have namespace in routes, you need to specify that with form_with
<%= form_with(model: [:powerusers, #assessment], local: true) do |form| %>
