Append to a forms hidden field list

[Bob Sleys]

Is there a hobo way to add to a forms hidden field list?

By default all hobo forms have a hidden-fields div with authenticity_token and page_path in it. I need to add a custom hidden field to a form and was thinking this would be a good place to put it but don't see a good way to do it.

Question: what are you trying to add as a hidden field?  Often you can get desired behavior with proper combination of permissions and preset values.

Are you sure you want to open that can of worms LOL.

Ok since you asked.  The problem revolves around a many to many relationship.

Simply put I wan to mimic the hobo standard behavior of adding a child record to a parent that is done though the auto_actions_for in the child controller.

Hobo will created the proper route if you add the auto_actions_for :model_a to say model_b of a many to many between model_a and model_b but dryml auto rapid forms don't work properly.  The auto form falls apart on the  <form owner="model_a" method="post" param> the owner param gives rapid a headache.  So if I remove the owner param I can get the form to generate but then when the new model is saved it doesn't have the appropriate assocation back to model_a.  Thus I'm looking to tuck model_a's id into an hidden field and then on the create method of model_b controller I can grab model_a via the hidden field and make the association.

Hope that made some sense.

Yeah, you can just do something like <after-field-list:><hidden-id-field:association /></after-field-list:>

I think you might need to set the relationship manually when you create the object though.

I have this in pretty much every application.dryml:

<def tag="hidden-field">
<%= hidden_field_tag(param_name_for_this, this) %>
</def>

Perhaps it should be added to Rapid, but it's a common enough pattern
that I'm sure it'd overlap with somebody's own tag somewhere.

I never bother putting it inside the hidden-fields div. Sounds like
the right thing to do in theory, but...

Thanks guys I got this working. Perhaps if I get some time I'll turn it into a Recipe for the cookbook.
