I'm currently working on a assignment for ruby on rails course I'm doing. I have to refactor a blog app written in Rails and add the functionality to merge articles.
What I did was to add a new text field in the form that is displayed when you edit the article (<%= text_field 'article', 'merge' %>). After I do that, it complains that there is no merge method in article model so I went ahead and implemented that.
I run the following migration:
class AddMergeWithToContents < ActiveRecord::Migration def self.up add_column :contents, :merge_with, :integer end
def self.down remove_column :contents, :merge_with end end
Then, when when accessing again the app it gives me the following error:
RangeError in Admin::SettingsController#update_database
bignum too big to convert into `long'
