Well, I spent an hour or more today tracking down an apparently undocumented behaviour in Hobo.
It turns out that for a new record the Rapid <form> tag inserts hidden fields for any attribute which is not nil, i.e. which has been initialized. I could not find this mentioned in the documentation for the <form> tag nor in the Hobo manual (not to say it isn’t there somewhere). This insertion of hidden fields caused an obscure bug when one of the inserted fields was for a serialized attribute with a class of Hash. Rails initializes the attribute to an empty hash for a new record. Hobo inserts a hidden field for this attribute in the form — which of course is rendered as a string. When the form is submitted, the attribute is given this string value (from the params hash) and an ActiveRecord::SerializationTypeMismatch error is raised. It took some sleuthing inside the Rapid form_helper method to find out what was happening and to discover that the <form> tag takes a hidden_fields attribute and that if you set this attribute empty then these hidden fields are not generated. This attribute of the <form> tag is not documented. Hobo giveth and Hobo taketh away. -- You received this message because you are subscribed to the Google Groups "Hobo Users" group.
