This works only if one record is matched, but there are two or more
records it only prints first of the record. Please help me, i''m just
beginner in rails
This is my controller:
def search
@info= Info.find_by_name(params[:desire])
redirect_to :action => ''list2'', :id => @info
end
And this is my view:
<% for column in Info.content_columns %>
<th><%= column.human_name %></th>
<% end %>
</tr>
<tr>
<% for column in Info.content_columns %>
<td> <%=h @info.send(column.name) %></td>
<% end %>

Is there a problem with my view file => list2.rhtml ?

I can''t believe how could be this thing so hard with rails.Info.find will return an array if you give it an array of ids. You need to iterate over that collection. Any entry level rails tutorial should cover this sort of thing.

Fred has (as usual) offered very good help. I believe that your problem is that you have poorly modeled routes. A ''list'' type of action is generally a collection method, not a member method, and thus has no id associated with it. It also makes little sense to respond to one request by fetching the necessary information and _always_ redirecting. Perhaps you should be using: render :action=>''list2'' instead. That way you''d be using the data that you''ve already gathered (@info) and simply rendering it out using the template from another action. Long story short, it''s not Rails that''s the problem, it''s having too loose a grasp on its principles.
