Calling Method
Is there a way to call a method if I only have a string that contains
the method name.
For example:
@methods = [''method1'', ''method2'', ''method3'']
@step = 1
# I want to call method2 which has a definition in this class

making an integer from a float
Does anybody know how to turn a floating-point number (i.e. 60.345) into
an integer by cutting off or rounding the decimal portion? Either
method, or both, would be quite welcome. Thanks! This forum rocks!

Where is the send() function?
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

checking date
Radrails created a field for date
<%= product.date_available.strftime("%y-%m-%d") %>
What does this mean?
Should the definition be date or datetime? I tried both and no results

setting widget attributes
I''m trying to set attributes of widgets in subclasses like the following.
class PersonTable < FXTable
def initialize(owner)
options = TABLE_COL_SIZEABLE
super(owner, nil, 0, options)
visibleRows = 5
...
end
end
visibleRows doesn''t get set.
However, if I do this
self.visibleRows = 5
then it does.
Shouldn''t it work without "self."?

negate the regexp in validates_format_of
Railsters:
ActiveRecord''s validation system puts other database systems to shame.
However, the newbies might not know how to write a regexp that
excludes a match, instead of tests for it. Understand - I''m just
asking this question to help them. I have been using Regexps since
''grep'' on Xenix! But the newbies here might not know how to do this:

with Items and Categories and have the related tables link up w/ the
default "scaffold :Items" command plus custom defenitions.

date validation
I''m hoping someone can help me (a Rails newbie) with this. Basically, I
need to verify that a date created with "date_select" is valid *before*
it''s sent off to the database for acceptance (as a valid date) or
rejection (as an invalid date). Given how easy the majority of validation
are in Rails, I''ve got to believe there''s a fairly simple way

Uploading files and writing them to server?
Where should I look for information on how to use Rails and Ruby to
accept the upload of a file and then to save that file to the file
system of my server?
I''m reading the "Uploading a file" section of Agile Web Dev with Rails,
but it''s geared toward saving the file in the database.
Any advice?
Thanks,
Jeff
