So I generate a scaffold with Rails 2.1.0 with a number of database fields. item:string accession_number:text description:text designer:string classification:string overall_dimensions:string auxiliary_parts:string overall_condition:string condition_description:text picture:binary accession_date:datetime provenance:text manufacturer:string design_date:string construction_date:datetime material_surface_finish:string medium_technique:string identification_markings:string picture2:binary recommendations:string exhibition_record:string conservation_record:string bibliography:text dimensions:string notes:text class:string old_box_numbers:string other_identification_numbers:string inventory_date:datetime inventory_recorded_by:string other_source_location_information:text other_location_information:text location:text box_number:integer collector:string collector_or_donor:string archaeological_site_name:string archaeology_site_number:string geographical_region:string picture1desc:text picture2desc:text insurance_appraisal:string And when I go to the scaffold new view, it tells me I have a nill object where I didn''t expect it. Normally, this happens when I haven''t specified the id of an Active Record object properly so the Controller doesn''t give the View a specific active Record object to play with. But in this case the model is simply Entry and my controller code is simply @entry=Entry.new. I can''t see where that wouldn''t give it an object to play with?

Hi Rob, So I tried changing class to type, without any success. I checked the development log and found the following entry: ActionView::TemplateError (You have a nil object when you didn''t expect it!

I have seen the error message The error occurred while evaluating nil.generated_methods) when you use a Rails reserved name field name "class" is most common offender, may be "type" as well. Change it to something totally different and see what happens. -Hari On Jun 18, 12:54 pm, Ron <stecklyena...-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org> wrote:> So I generate a scaffold with Rails 2.1.0 with a number of database > fields. > > item:string accession_number:text description:text designer:string > classification:string overall_dimensions:string auxiliary_parts:string > overall_condition:string condition_description:text picture:binary > accession_date:datetime provenance:text manufacturer:string > design_date:string construction_date:datetime > material_surface_finish:string medium_technique:string > identification_markings:string picture2:binary recommendations:string > exhibition_record:string conservation_record:string bibliography:text > dimensions:string notes:text class:string old_box_numbers:string > other_identification_numbers:string inventory_date:datetime > inventory_recorded_by:string other_source_location_information:text > other_location_information:text location:text box_number:integer > collector:string collector_or_donor:string > archaeological_site_name:string archaeology_site_number:string > geographical_region:string picture1desc:text picture2desc:text > insurance_appraisal:string > > And when I go to the scaffold new view, it tells me I have a nill > object where I didn''t expect it.

Ron, First, ''type'' isn''t much better than ''class'' since ''type'' is used to indicate Single-Table Inheritance in ActiveRecord. Now, I first looked to see if ''dimensions'' was actually a database column. Seems like it is (and spelled consistently in both places, too). I can''t try to replicate your error because I don''t have 2.1 installed, but can you avoid it by commenting out line 8? (<%# is an erb comment) Do other text_field calls for this object then work? From the low line number, I''m guessing that this is the first text_field in your view. I may not be helping you much, but this is the kind of controlled descent I''d make into the rabbit hole. -Rob On Jun 20, 2008, at 12:36 PM, Ron wrote:> Hi Rob, > > So I tried changing class to type, without any success.

So I tried changing type/class to something completely random--in this case binder. (I call my variables that when I''m frustrated--I know, its weird). So, its still coming up. I even tried changing dimensions value when I did that. I wonder if my name for the controller is reserved, entry? None of the other text fields for the scaffold actually work. Really strange. btw... I LOVE that phrase "controlled descent into the rabbit hole." I''m going to use it down the road, if that''s ok.
