TimeParseable

Time-parse your front-end text-fields.

$ script/plugin install git://github.com/cementhorses/time_parseable.git

Example

Let's say we want to use text fields for a model...

# create_table do |t|
#   t.timestamp :published_at, :archived_at
# end
class NewsItem < ActiveRecord::Base
  time_parseable
end

Now your NewsItem has published_at_string and archived_at_string, which, on assignment, are automatically parsed with Time.parse.

news_item.published_at_string = 'April 30, 2008'
news_item.published_at # => Wed Apr 30 00:00:00 -0000 2008

If you only want to parse the published_at column, scope it.

time_parseable :published_at

Time.parse is a bit broken, though.

Time.parse('Cement Horses').to_s == Time.now.to_s # => true

We've fixed it, and added some validation.

news_item.archived_at_string = 'Cement Horses'
news_item.archived_at # => nil
news_item.errors.on(:archived_at) # => 'is invalid'

Now, all you have to do is throw it in a form_for, and time_parseable will do the rest.

<%= f.label :published_at_string, 'Publish at' %>
<%= f.text_field :published_at_string %>

We should probably mention that you can reduce user error by dividing the task into bite-sized pieces:

<%= f.label :published_date_string, 'Publish on' %>
<%= f.text_field :published_date_string %>
<%= f.label :published_time_string, 'at' %>
<%= f.text_field :published_time_string %>

Yes, published_date_string and published_time_string get created with the rest.

The fields, once populated, will return a strftime-formatted result. You can choose the format (but choose wisely, it should parse to the same result).

time_parseable :format => {
  :date => "%m/%d/%Y", :time => "%I:%M%p"
}
