Import CSV to database using Rails 4.0.3

I am new to Ruby on Rails.

I am using Rails 4.0.3, Ruby 1.9.3.

I tried to import CSV file from the sample "396-importing-csv-and-excel-master" But it is throwing error.

Error:

attr_accessible is no longer in use

and suggests to use Strong parameter. Can any one help me to import CSV using strong parameter?

Let's say you are importing Tasks. Use this way for strong parameters

def self.import(file)    
  CSV.foreach(file.path, headers: true) do |row|
    task = find_by_id(row["id"]) || new
    parameters = ActionController::Parameters.new(row.to_hash)
    task.update(parameters.permit(:id,:name))
    task.save!
  end
end

attr_accessible is no longer use in rails 4. In rails4 just like params.require(:person).permit(:name, :age)

I think this can help you
