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
"index.html.erb":
<h1>Werken met valuta</h1>
<table> <tr> <th>Valuta</th> <th>Omschrijving</th> <th>Koers</th> <th>Aantal decimalen</th> </tr>
<% for qvvaluf in @qvvalup %> <tr> <td><%=h qvvaluf.qvqvcode %></td> <td><%=h qvvaluf.qvqvomsc %></td> <td><%=h qvvaluf.qvqvkoer %></td> <td><%=h qvvaluf.qvqvaant %></td> <td><%= link_to 'Show', qvvaluf %></td> <td><%= link_to 'Edit', edit_qvvaluf_path(qvvaluf) %></td> <td><%= link_to 'Destroy', qvvaluf, :confirm => 'Are you sure?', :method => :delete %></td> </tr> <% end %> </table>
