Ok so could anyone tell me what this is called so I can look it up
rather posting questions in this forum all the time. I have had to post
something to learn how to do the following:
Model.send("field#{x}")
and
session["field#{x}".to_sym]
now I am trying to do this for variables for example:
@details = RDetails.find(id)
1.upto(15) do |x|
@details.?????("field#{x}")
end
@details.save
I don''t even know what to look up. I tried string methods, model
methods, variable methods...
Thanks in advance

I''m thinking you maybe want: @details.send("field#{x}=", "some val here") That would set all those fields to "some val here". -philip --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Sorry about that I meant to say:
@details.?????("field#{x}") = "some value"
And what you said works perfect, that''s exactly what I was trying to
do.
I understood what the .send was doing before, I didn''t realize I could
also use that to set the values as well using:
@details.send("field#{x}=", "some val here")
Thanks a lot

So, @person.first_name is a way of sending the ''first_name'' message to the @person object. It is equiv to @person.send(:first_name) If we wanted to set the first name of a person we could type: @person.first_name = ''Mikel'' But we could also type: @person.send(:first_name=, ''Mikel'') I would recommend you to get the latest version of the Pickaxe Ruby book, it will teach you a lot about these things.
