rails application undefined method for class

Question

I rewrote my create function in my scaffold Review after making it associated with my Concert model. When I try to submit a form to create a review though I get an error saying

undefined method `reviews' for #Class:0xab9972c>

def create
    @review = Concert.reviews.create(review_params) 
end

My Concert model looks like this

class Concert < ActiveRecord::Base

validates_presence_of :artist
validates_presence_of :venue
validates_presence_of :date

has_many :reviews
end

and my Review model looks like this

class Review < ActiveRecord::Base

    validates_presence_of :artist
    validates_presence_of :venue
    validates_presence_of :date

    belongs_to :user
    belongs_to :concert
end

I also added the relations within my migration files but I still get the error. Can someone explain to me what is causing this and how I could go about creating a review that belongs to a concert?

Answer 1

The association has_many :reviews is an instance method. I suspect that in your create method you want something like this:

def create
    @concert = Concert.new
    @concert.save
    @review = @concert.reviews.create(review_params) 
end
