>From the rich type docs on the website and reading the list archives I have made the following changes to create a Dollars rich type:
In a new file: app/models/dollars.rb *class Dollars < DelegateClass(BigDecimal) COLUMN_TYPE = :decimal HoboFields.register_type(:dollars, self)end* Two tag definitions in application.dryml *<def tag="view" for="Dollars">$<%= number_to_currency(this) %></def><def tag="input" for="Dollars" attrs="name"> $ <%= text_field_tag(name, this, attributes) %></def>* And the following field in my Project model: *fundingtarget :dollars, :precision => 12, :scale => 2, :default => 0* So I run "rails s". And look at my project show page: there is no "$" near my fundingtarget field. I change the value to 250. It is successful, and the SQL is: UPDATE "projects" SET "fundingtarget" = ?, "updated_at" = ? WHERE "projects"."id" = 2 [["fundingtarget", #<BigDecimal:51fd548,'0.25E3',9(18)>], ["updated_at", Wed, 19 Aug 2015 05:42:39 UTC +00:00]] Now I remove the "$" from the Dollars view tag definition. Refresh the page and there is now a "$" in my funding target field ($250 is shown). I edit and change the field to 300 and get the following error: TypeError: can't cast Dollars to decimal: UPDATE "projects" SET "fundingtarget" = ?, "updated_at" = ? WHERE "projects"."id" = 2 And the SQL was: UPDATE "projects" SET "fundingtarget" = ?, "updated_at" = ? WHERE "projects"."id" = 2 [["fundingtarget", #<BigDecimal:5564e20,'0.3E3',9(18)>], ["updated_at", Wed, 19 Aug 2015 05:45:09 UTC +00:00]] So I go back to my view tag for Dollars and re-add the "$". Save and view the show page. Now there are *two* dollar signs ($$250 is shown!). Once again I try an edit, changing the value to 300 and get the same TypeError as before. The only way to avoid errors is to stop and restart the server at which point I can view and update, but no dollars sign is shown regardless of the starting content of the Dollars view tag. Any change/save of this tag (even removing the "$"!) results in a "$" being shown on the page, but errors on update.
