Re: Edit the form

this is a mailing list, don''t post the same question several times

You must use form_for instead of form_tag or add the id parameter
manually

<% form_for @editresortbasic do %>


But reading your other posts I would recommend working through some
basic
Rails tutorials, so you understand at least a bit what you are doing
here

Re: Edit the form

there are two main ways to create forms in RoR:
- use the helpers that end with _tag, those create "pure" html
tags and are not too much aware of objects contents (like
@editresortbasic)
- use it like that:

in the controllers edit action get @editresortbasic like:

def edit
  @resort_basic = ResortBasic.find(params[:id])
  # this assumes, that the id of the ResortBasic to be edited is
handed to this action
end

then you can built your view like this:

<% form_for @resort_basic do |f| %>
  <%= f.text_field :name %>
<% end %>

That way the form "knows" of the @resort_basic object
and using the textfield that way, Rails knows that it''s linked
to this object and reads the value from @resort_basic.name
Same for all the other fields in your form that are columns
in the resort_basics table.

you can read many details about that in all RoR online tutorials,
and you should (must) get comfortable with that kind of Rails syntax.
There is not much sense in starting a project without knowing
at least the basic syntax of the framework.

Re: Edit the form

You are passing params[:id] as argument to find, so no need to use 
find_by_id. Its enough to use
@resort_basic =ResortBasic.find(params[:id])

Re: Edit the form

What does the link which directs you to the edit method for the WizardS 
Controller look like?  You aren''t getting an ID passed in the params.

Your edit.html.erb code has nothing to do with this error, this comes 
from the form that is going TO the edit view.

How is the link TO the edit form spec''ed? I assume you''re
currently on
an index or show view...
