Hey,
i am very new with handling Ruby on Rails, so i did the Video-Tutorial
of "video2brain".
They use an older Version of Rails (1.8.. - i guess) and in an
controller-file they want me to do the following:
class FormController < ApplicationController
def index
@form = Form.find(:first)
@form.update_attributes(params[:form])
@detail = @form.detail
@detail.update_attributes(params[:detail])
end
end
But now it says, that the method "detail" (in @details @form.detail)
does not exist. I tried to get help with google - but
that wasnt succesful.

This should all be in the tutorial however. I think you might be much better finding a tutorial for the version of rails you are using however.

That was almost successful ..I used the "has_one" -command and deleted the following line in form_controller.rb: "@detail.update_attributes(params[:detail])". Actually i can see two boxes - the second one is the "detail"-box. the first one saves my changes. the detail-box does not. Pasting the "@detail.update_attributes(params[:detail])" -line into the form_controller.rb , the following error message appears: " NoMethodError in FormController#index You have a nil object when you didn''t expect it! You might have expected an instance of ActiveRecord::Base. The error occured while evaluating nil.update_attributes" Whats wrong?

Therefore i deleted the ""@detail.update_attributes(params[:detail])" line in form_controller.rb, wrote a short text in both boxes and pressed "Speichern" (> the German word for "Submit"). At least i got the following post in my log file: Processing FormController#index (for 127.0.0.1 at 2010-09-24 09:11:59) [POST] Session ID: 7d9c4ddeaff0f55ddf9356003f9a1750 Parameters: {"commit"=>"Speichern", "action"=>"index", "controller"=>"form", "form"=>{"kurztext"=>"This is a test for the talk"}, "detail"=>{"detailtext"=>"Test for the talk"}} [4;35;1mForm Load (0.000000) [0m [0mSELECT * FROM forms LIMIT 1 [0m [4;36;1mForm Columns (0.000000) [0m [0;1mSHOW FIELDS FROM forms [0m [4;35;1mSQL (0.000000) [0m [0mBEGIN [0m [4;36;1mForm Update (0.031000) [0m [0;1mUPDATE forms SET `checkbox` = 0, `detail` = '''', `auswahlbuttons` = ''Nein'', `kurztext` ''This is a test for the talk'', `datum` = ''2008-06-01'', `detailtext` '''', `auswahl` = ''RoR'', `langtext` = ''Mein Langtext...''

From earlier in the post-stream:
class FormController < ApplicationController
def index
@form = Form.find(:first)
@form.update_attributes(params[:form])
@detail = @form.detail
@detail.update_attributes(params[:detail])
end
end
From your log:
{"commit"=>"Speichern",
"action"=>"index",
"controller"=>"form",
"form"=>{"kurztext"=>"This is a test for the
talk"}, "detail"=>{"detailtext"=>"Test for
the talk"}}
Something is truly bizarre with this example you are trying
to follow... and I can''t say that I fathom the intent of
the example in the tutorial. So I went to look, and found a
PDF about Rails at video2brain, but unfortunately, Ich spreche
kein Deutsches.
Strange issues with this example:
You generally don''t POST to the index method... that''s
usually a GET.
This code will always be modifying the first form due to the
Form.find(:first) statement... perhaps there is only supposed to
be one.
The detail model in params doesn''t contain a form_id. You could
remedy that by:
@form = Form.find(:first)
@form.update_attributes(params[:form])
if @form.detail
@detail = @form.detail
else
@detail = Detail.new
end
@detail.form_id = @form.id
@detail.update_attributes(params[:detail])
That should at least get you a value for form_id in
the detail model (you did add form_id as integer to your
details table, no?))
But this example is "wrong" in so many ways. Finish it if you must,
then promptly forget this video2brain... gibberish.
Step up to Rails3, and find a couple of Rails 3 tutorials. You''ll be
much better served spending your time on those.
