undefined method `save' for nil:NilClass for my app - ruby-on-rails

Question

[enter image description here][1]
I keep getting this error message and can not figure out why it is. I believe it is because #resturant is nil. But I do not understand why it is nil.
Is there anyway to 'print or console log' the response so I can see what the problem is

Here is the model
class Resturant < ApplicationRecord
mount_uploader :image, ImageUploader
serialize :image, JSON # If you use SQLite, add this line
belongs_to :user, optional: true
validates :name, :description, :location, :resturant, :glutenfree, :vegan, presence: true
validates :description, length: {maximum: 1000, too_long: "%{count} characters is the maximum allowed"}
validates :title, length: {maximum: 140, too_long: "%{count} characters is the maximum allowed"}
end
here is the controller:
class Resturant < ApplicationRecord
mount_uploader :image, ImageUploader
serialize :image, JSON # If you use SQLite, add this line
belongs_to :user, optional: true
validates :name, :description, :location, :resturant, :glutenfree, :vegan, presence: true
validates :description, length: {maximum: 1000, too_long: "%{count} characters is the maximum allowed"}
validates :title, length: {maximum: 140, too_long: "%{count} characters is the maximum allowed"}

Answer 1

You have a typo. (It often takes a second set of fresh eyes to see these.)
You have accidentally pluralized resturant in your create action but then are using the singular later on.
You have:
#resturants = Resturant.new(resturant_params)
Change it to:
#resturant = Resturant.new(resturant_params)
(You are also misspelling "Restaurant" throughout your entire application. It is up to you if you'd like to fix that or not. I know I myself have trouble spelling that one for some silly reason.)
