1. Create your gem:

Here is the most modern approach to gem crafting:

bundle gem gemname
cd gemname

edit your_gem.gemspec and add description, summary, required gems and optional website. Add required gems for development such as rspec, rails or minitest to the Gemfile.

rspec --init
touch spec/your_gem_spec.rb

Saving dynamic serialized fields with fields_for in Rails

February 23, 2015

Tell you model to serialize it as a struct and create a setter to build the struct on create.

# post.rb model
serialize :content, OpenStruct
def content=(v)
  self[:content] = OpenStruct.new(v)
end

Then you can add any form elements you want for content.

-#form partial

= f.fields_for :content, @post.content do |ff|
  .field
    = ff.label :name
    = ff.text_field :name
  .field
