I am "new" to Ruby and Rails and jumping right in. That''s for
me the
best way to learn quickly. I am trying to do a simple project on a
legacy database. I performed the following steps:
Created a new project, then with the generator scaffold created a
simple "recipes" table.
I am coming from IBM iSeries where we have tables and so called record
formats. For example the table is named "qvvalup" and the record
format is named "qvvaluf", where the record format "handles a
single
record" so to speak. So we have the same kind of concept as with the
rails pluralization: recipes and recipe.
I made copies of folders and files and renamed accordingly. A few
examples. The model file "recipe.rb" I copied to
"qvvaluf.rb". And the
folder "apps/views/recipes" I copied to
"apps/views/qvvalup". I have a
"qvvalup_controller.rb" and so on. Also did a search and replace in
all the files self. So "recipes" to "qvvalup" and then
"recipe" to
"qvvaluf". Did put in a "map" in "routes.rb" as
well:
map.resources :qvvalup
Next step was editing my model file "qvvaluf":
set_table_name "qvvalup"
set_primary_key "qvqvcode"
to be able to handle the pluralization and primary key.
I am getting an error when going to localhost:3000/qvvalup. The error
seems to be in my "index.html.erb" when it is trying to create my
"show link":
undefined method `qvvaluf_path'' for #<ActionView::Base:0x4953c34>
My "index.html.erb" is below and I can''t find anything that I
might
have forgotten to rename or whatever. Is it maybe the routing that is
going wrong here ? Or something else ? Any help appreciated...
Thanks,
Mark

So the map to recipes is still in there. I addad my line just after the map recipes line. The rest is left as well. So at the bottom of the file, there are two ''general" routes. -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

qvvalup is not the same as qvvaluf, unless you''re speaking a language I''m not recognising. Rails works "best" with english words and pluralization. Somewhere in your app you''re referencing qvvaluf_path... probably a scaffold somewhere.

Got a stack trace for us? > ----- > Ryan Bigg > Freelancer > http://frozenplague.netI am working with a legacy database and so pluralization is out of the question. But in the same way Rails uses pluralization, we have "generalized" and use P as suffix for tables and F as suffix for records. Hence the qvvalup and qvvaluf. You are right for the scaffold. Used the scaffold generator to provide for a skeleton for the recipes example, then just did a very basic search/replace, replacing recipes with qvvalup and recipe with qvvaluf. Below a stack trace and my index.html.erb where you can find all my "replacements" of recipes and recipe. Perhaps I should have replaced recipe with qvvalup insteas of qvvaluf ?
