Hi all, Quick setup - I''ve got a table Foo. Foo has a foreign key (bar_id) to the table Bar. The Bar table has an "id" and "name" column. Assume a 1:1 relationship. The issue I''m trying to resolve (or rather, be lazy about) is with regards to Foo.content_columns. By default it doesn''t pickup the foreign key. What I''m wondering is if

I''ve got a belongs_to / has_many relationship working, however I don''t know if I can still use content_columns (or any other shortcut) in my view that displays my object. E.g., Employee belongs_to Department I''m displaying an Employee. Will content_columns contain employee.department.name? Or how else could I do this so I don''t have to hard-code column

I have a database with a couple of tables. One table called spares has foreign keys in another called equipment. When I create a new record, it is added to the spares table however the list action does not show all the columns in the table. It only shows those columns that are not foreign keys. I am using the default action generated by scaffold for list. Why is that so? Do i need to re-write my

Hi all, In the code below I don''t understand: 1. Why I have to prepend overriden method content_columns with "self." to get it working? 2. Why column_for_attribute method is not working (no such method?) even if SomeTable is subclass of ActiveRecord::Base which have public column_for_attribute method? > class SomeTable < ActiveRecord::Base > > def

My code executes fully: <% for column in ModelName.content_columns %> <th><%= column.human_name %></th> <% end %> but it does not pick up any columns in my model''s table that end in "_id". Is this by design? Is there a helper method that will reference the related tables? Or will I need to code the column titles and detail records by

I need to export some data to an Excel file and found a reference in the HowTo section of the Rails Wiki. Followed it to the letter: added "export" action to controller, copied export.rxml and changed in accordance to model. When I call the export action I keep getting "undefined method `content_columns'' for #<Employee". The ActiveRecord mention content_columns

I''ve gone once through the Agile book and am now attempting my own rails app. I''ve created a table named ''volunteers'' with over 15 columns. The problem is the default list.rhtml that is created with the scaffold, shows all the columns. I only want to show 4 of them with the list view. Where would I start to only return a handfull of columns to the

Hi, in the tutorial "4 Days on Rails" the following code fragment is used: ,---- | <% for column in Category.content_columns %> | <td><%=h category.send(column.name) %></td> | <% end %> `---- Apparently, the send() function returns the column value by name, but where does this function comes from? Unfortunately, neither the tutorial nor the API

All, I have ordered AWDWR and am anxiously awaiting its arrival. In the meantime I still am playing with ROR using radrails. I have a few questions ...

I?m following along a few tutorials on the web and trying to implement my own example, but I must be missing something because I can?t get has_many or belongs_to to work like I expected. now I have watched all the videos and made a cookbook several times with different interfaces. what I''m looking for is *not* a code snippet to solve something (because I already have that),

Hey All ! I have a form which contains two models. I would like both models to be validated, but have their validations aggregated on the page. If I do: <%= error_messages_for(:model1) %> <%= error_messages_for(:model2) %> It puts two big validation blocks on the page. I would like all the errors from both models, but only in one validation box. Is this possible ? All my attempts

All, I did a scaffold for a model and I ended up with this code in list.rhtml: <% for column in TargetList.content_columns %> <td><%=h target_list.send(column.name) %></td> <% end %> Where is the "send" method and what does it do? I can''t find it on ActiveRecord::Base? I assume that it returns a value based on the column id but I

Hey All, I have two tables.. One belongs to another. Why can''t I reference table1.table2.attribute? Specifically, using scaffolding: property.rb - has_one :PropertyType property_type.rb - has_many :Properties property_controller - def list @property_pages, @properties = paginate :properties, :per_page => 10 end list.html: 1. <% for property in @properties %> 2.

Hi, I''m a newcomer to Ruby and to Rails, and am having a problem with character encoding. Now, I know ruby doesn''t handle unicode...but, characters like ? (eacute) and ? (ccedil) are part of the iso-8859-1 charset, so it shouldn''t be a problem, right? But, for some reason, the string functions still seem to hang on those characters. As an example, in a brand new rails
