I think I am going blind, because I cannot find what is wrong with the
following. The bad thing is that I had it working, made couple of
changes, reverted back to the original, now it doesn''t work.
I have been trying to figure out why this isn''t working way too long,
to the point my vision is blurring.
<div style="border:3px solid #999">
<% form_for :categories, :url => {:action => "show_tasks"}
do |form|
%>
Select Category:
<%= form.collection_select :name, @categories, :id, :name %>
<%= submit_tag "View" %>
<% end %>
</div>
here is the error message
NoMethodError in Mytasks#index
Showing app/views/mytasks/index.rhtml where line #10 raised:
undefined method `name'' for #<Array:0xb7611edc>
Extracted source (around line #10):
7: <div style="border:3px solid #999">
8: <% form_for :categories, :url => {:action =>
"show_tasks"} do |
form| %>
9: Select Category:
10: <%= form.collection_select :name, @categories, :id, :name %>
11: <%= submit_tag "View" %>
12: <% end %>
13: </div>
Thanks for the help

Take a look at your controller where you''re populating @categories.

Sorry, I should''ve mentioned that there has been no changes to the
controller since I had it working.
Here is the index method from the controller
def index
@categories = Category.find(:all)
@tasks = []
end
But the error is in regards to to the *select control. If I remove
line 10 from the index.rhtml file it renders to the browser without
any errors.

Hi Chris, you should be able to do the following: <%= form.collection_select ''task'', ''category_id'', @categories, ''id'', ''<some_category_attribute>'' %> This invocation will generate a select tag name="task[category_id]" with options of form <option value="category.id">category.<some_category_attribute></option>. The option with category.id == user.category_id will be selected. Now, I''m guessing the following from you previous e-mail: task belongs_to category category has_many tasks Thus, I''m seeing the following relationship: class Task < ActiveRecord::Base belongs_to :category end class Category < ActiveRecord::Base has_many :tasks end Please note that Task model contains the foreign key, ''category_id'', because it has the belongs_to declaration.

Since I am just playing around with things I am constantly re- formatting how things are arranged on the screen. How this is supposed to work, is that at the top of the screen there is a select list containing the categories, that combined within the button beside it, allows the user to easily view the todo''s for each of the categories. So the select control that I am having problems with isn''t yet, at the time of the problem, related to the tasks just yet. I want to fill the select control with all the categories that exist in the database. Thanks for the help, I really appreciate it.

maybe this will help. I totally removed the linkage to the categories
and tried to hard code some values, with some random names
<div style="border:3px solid #999">
<% form_for :categories, :url => {:action => "show_tasks"}
do |form|
%>
Select Category:
<%= form.select "some_names", %w{Chris, Andy, Wally} %>
<%= submit_tag "View" %>
<% end %>
</div>
Here is the error message
================== NoMethodError in Mytasks#index

undefined method `some_names'' for #<Array:0xb757f654>

Hi, you should be able to do the following:
1) Define this in the relevant model.
category_type = [
[ "Chris", "1" ]
[ "Andy", "2" ]
[ "Wally", "3" ]
]
2) Add this code to the relevant view.
<%= form.select :some_names, <class_name>::category_type %>
Note: <class_name> := The name of your model class. For example,
Category
Good luck,
-Conrad

Here is the updated snippet from the rhtml file
++++++++++++++++++
<div style="border:3px solid #999">
<% form_for :categories, :url => {:action => "show_tasks"}
do |form|
%>
Select Category:
<%= form.select :brothers, Category::BROTHERS %>
<%= submit_tag "View" %>
<% end %>
</div>
Here is the addition of the BROTHERS array in the category model
++++++++++++++++++
class Category < ActiveRecord::Base
has_many :tasks
BROTHERS = [
["1", "Chris"],
["2", "Tim"],
["3", "Tom"]
]
end
And here is the error :(
++++++++++++++++++++
