http://railscasts.com/episodes/396-importing-csv-and-excel?view=asciicast Say no method import in dreams controller.

Any body knows a good way to import data to my app? Thanks! Felipe

Answer 1

If it says no method import in dreams_controller it would appear that you did not properly define the import method. In other words, you either skipped or messed up this portion of the tutorial:

/app/controllers/products_controller.rb

def import
  Product.import(params[:file])
  redirect_to root_url, notice: "Products imported."
end

If you could post the code it would be much easier to help.

Answer 2

The missing method is inside dream.rb model . You need this:

def self.import(file)
  CSV.foreach(file.path, headers: true) do |row|
    Dream.create! row.to_hash
  end
end

That is because when you call Dream.import(params[:file]) you are actually calling the class method of the Dream model.
