I''ve seen some similar questions to this but I cannot find the answer.
I have a simple form that is supposed to save some values into the
database. However, when I call save, the record is saved with null
values instead of the values provided in the form.
As you can see by the following console output, the parameters are
being posted properly, but for some reason they are not being entered
into the database. I''m not doing any validations or anything else.
I''m
also not receiving any errors.
What''s the deal?

Alright I figured out how to get it to work, but I''m still not sure why. First off, I was using the form_tag method of creating forms. Then in my controller I was doing @motorycle = Motorcycle.new(params[:motorcycle]) @motorcycle.save This did not work. What I''ve done now is change the controller to: @motorcycle= Motorcycle.new @motorcycle.make = params[''make''] @motorcycle.model = params[''model''] @motorcycle.year = params[''year''] @motorcycle.save And that works! So my question becoms, why do I have to manually assign the parameters when using form_tag, and I don''t when using form_for? Thanks Dana
