[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 [1]: https://i.stack.imgur.com/sHUrz.png

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"}

CodePudding user response：

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.)
