method from string?

I am sure this is doable but I can''t find a specific example and my
brain is frazzled.
Basically, I am doing a whole load of in-place editing and need
methods to support the updates.

Here is what I am doing now:

  def set_blog_website
    faq = Faq.find(params[:id])
    faq.blog_website = params[:value]
    faq.save!
    @faq = faq
    do_ret
  end

Surely there is a generic way I can do this so that I can do something
like
def set_blog_website
 @faq = update_column(:blog_website)
end

def update_column(column_name)
  faq = Faq.find(params[:id])
  faq.column_name = params[:value]<<-- here''s what I
don''t know how to
do!
  faq.save!
    @faq = faq
    do_ret
end

Any ideas on how I could set the attribute? Faq is an
ActiveRecord::Base object.

Thanks

I think this will do what you want:

faq[column_name] = params[:value]

Re: method from string?

Thanks guys - I found this does the trick:

  def set_column(column_name)
    faq = Faq.find(params[:id])
    faq.update_attribute(column_name, params[:value])
    @faq = faq
    do_ret
  end

Re: method from string?

Why aren''t you just defining it as @faq at the start? That would get
rid of
the needeless definition of the local variable "faq" and the line
where you
tell it the instance is the same as the local.

What is do_ret?
