Hello.
Here are the two offending lines of code: They are designed to
provide a drop down list (working).
@bank =Org.find(:all,
:conditions=>"org_type=''bank''")
@bank.unshift(Org.new
("name"=>"none","id"=>1000,"addr1"=>"a","addr2"=>"b","city"=>"c","provin
ce"=>"d","post_code"=>"x",
"country"=>"Canada","gst_number"=>"y","logo"=>"null","parent"=>0,"inv_pr
efix"=>"z","org_type"=>"bank"))
The problem is that when I inspect the @bank array I find that it
does not have an "id" field. This is a problem because it means I
cannot save the invoice record.
Any ideas?

Could it be that the ID is supposed to be assigned by the DB on create? That was my guess. Dave

That was my guess.The Model.new and the Model#attributes= methods ignore any setting of the ID to prevent malicious attacks from the client to populate @params and set the id. You have to set it separately, but it''s best to let the DB assign it.

David: Thanks. I guessed the same but that was helping. So I "cheated". I solved it this way (I''d still like to know what the problem was) if @invoice.bank_id = "null" @invoince.bank_id = 0 Which works for my purpose. These two lines of code come just before the Invoice.save method. It works, but I feel kind of dirty. I feel there is something here that I have not understood that I should have understood. I hope that this workaround / kludge / abuse of ruby purity may be of assistance, if you can''t find a cleaner method. bruce On 18-Nov-05, at 1:27 PM, David Clements wrote:> On 11/18/05, Bruce Balmer <brucebalmer-ee4meeAH724@public.gmane.org> wrote: >> Hello. >> >> Here are the two offending lines of code: They are designed to >> provide a drop down list (working). >> >> @bank =Org.find(:all, :conditions=>"org_type=''bank''") >> >> @bank.unshift(Org.new >> ("name"=>"none","id"=>1000,"addr1"=>"a","addr2"=>"b","city"=>"c","pro >> vin >> ce"=>"d","post_code"=>"x", >> >> "country"=>"Canada","gst_number"=>"y","logo"=>"null","parent"=>0,"inv >> _pr >> efix"=>"z","org_type"=>"bank")) >> >> The problem is that when I inspect the @bank array I find that it >> does not have an "id" field.

Hello. I have to create a PDF from ruby (partly because browsers are so poor at printing html pages - why is that?). I am looking at PDF::Writer. Does anyone have any suggestions as to a better package than that - if there is one? tia bruce
try using Org.create instead of Org.new (and remove the id attribute of
course). create will attempt to save and return the new record. if the
object could not be saved, then the unsaved object is returned.
@bank.unshift(Org.new("name"=>"none",
"addr1"=>"a",
"addr2"=>"b",
"city"=>"c",
"province"=>"d",
"post_code"=>"x",
"country"=>"Canada",
"gst_number"=>"y",
"logo"=>"null",
"parent"=>0,
"inv_prefix"=>"z",
"org_type"=>"bank"))

If, however, you end up not liking the PDF::Writer API, I can recommend that the Ruby implementation of FPDF produces nice looking documents, even though I can''t stand the API. PDF::Writer will be taking some ideas from the original PHP implementation of FPDF for future releases, but the overall capabilities of PDF::Writer are greater than those offered by FPDF. -austin -- Austin Ziegler * halostatue-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org * Alternate: austin-/yODNl0JVVCozMbzO90S/Q@public.gmane.org
