How do I force ActiveRecord to reload a class?
I always used new models in migrations
MyBlog < ActiveRecord::Base set_table_name 'blogs' end def self.up MyBlog.all.each do |blog| update_some_blog_attributes_to_match_new_schema end endBut Blog.reset_column_information is more convenient.
Create new instances:
Old_blogs = Blog.all# change/modify db table in here
New_blogs = Blog.all # this should be reloaded or you could use the .reload on this# change information, load old into new
ex.
Old_blogs.each do |blog| New_blogs.find(blog.id).title = blog.titleend
