Trivial syntax error: Unexpected ')'

Rails
1

I am a Rails newbie but have programmed other languages/frameworks
earlier.

There’s a trivial syntax error I can’t for the life of me figure out.
I am following the well-known Ruby On InstantRails tutorial from here:
http://instantrails.rubyforge.org/tutorial/index.html

I am overriding the default ‘edit’ method on the recipe controller. I
get the error in the edit.rhtml while creating the drop down for
displaying categories.

The relevant snippet is produced below:

Category <%= @categories.each do |category| %> > <%= category.name %> <% end %>

I don’t see anything wrong with that. However, I get an error as
follows:

compile error
./script/…/config/…/app/views/recipe/edit.rhtml:37: syntax error,
unexpected ‘)’
_erbout.concat “\t\t\t\t\t\t”; _erbout.concat(( @categories.each do |
category| ).to_s); _erbout.concat “\n”

^
./script/…/config/…/app/views/recipe/edit.rhtml:87: syntax error,
unexpected kEND, expecting ‘)’

I can gather it is complaining about some misplaced paranthesis and
‘end’ statement. However, there is no other enumeration/anonymous code
block in the code other than the one shown above.

Help appreciated.

<%= @categories.each do |category| %>

should be
<% @categories.each do |category| %>

Good lord! I can be so careless. Thanks a lot, Thorsten M… This
is the second time I made this mistake. I’ll be more careful for
myself in the future.

Just one other thing.

The ‘textarea’ I have for displaying instructions inserts many leading
and trailing spaces around the actual values. I checked and the
database records also have the leading and trailing spaces.

However, when I choose to edit a record and trim the trailing and
leading spaces around the instructions and issue an update, the spaces
are not trimmed. The next time I edit the record, they still appear.

Can you help me with this?
