Hi,
You are welcome to comment on every aspect of this post -- not just the core
question at the bottom.
My application renders forms previously stored in the database. A Form
consists of Elements:
t.references :form,
:comment => 'What form we belong to.'
t.decimal :ordering,
:comment => 'In what order we should appear.'
t.string :name,
:null => false,
:comment => 'Name.'
t.string :title,
:comment => 'Title.'
t.string :ml_type,
:null => false,
:comment => 'Markup language type.'
t.text :value,
:null => false,
:comment => 'Value.'
t.text :flags, :comment => 'Flags.'
ml_type could be 'text', 'select' or any other HTML form type.
Models:
class Element < ActiveRecord::Base
# Relationships
belongs_to :form
# Validations
validates_numericality_of :ordering
validates_presence_of :name
end
class Form < ActiveRecord::Base
has_many :elements
end
An Element should never be orphaned (i.e. without a Form). So if you want to
add an Element, you go to
http://localhost:3000/forms/1
.. which shows a Form's name with its Elements.
At the bottom of the Forms#show page I have a link 'New Element' which links
to:
http://localhost:3000/elements/new?form_id=1
Problem here is that if you click Create and validation doesn't pass, it
forgets about the form_id parameter.
How can I make it remember the form_id?
Best regards,
CmdJohn
