Can anyone see the error here?

Alan Morley asked in Rails

NameError in RecipesController#new

uninitialized constant RecipesController::Category


def new

@recipe = current_user.recipes.build

@categories = Category.all.map{ |c| [c.name, c.id] } <-- saying this lines wrong

end




def create

Hey Alan,

What exactly is the error message?

Also, you should be able to accomplish the same thing using pluck which is more performant, you also don't have to use `all` for this:

@categories = Category.pluck(:name, :id)

Look like it can't find the `Category` model. Did you check to make sure there isn't any misspelling  in the `Category` model name?

Sorry, I didn't see that line before

As Toan said, check the spelling and file names for your category model. You should have a file in the models directory called category.rb (all lowercase) with class Category < ApplicationRecord (rails 5+) or class Category < ActiveRecord::Base if <= Rails 4
