Re: [Zope] Populating a :list variable from the results of a ZSQL method
tone, How about (untested): where 'dboptions' is the string pulled from the DB, and 'options' is the list needed. This would then give you take the string "['1','2','3']" and turn it into the list [1,2,3]. hth Phil - Original Message - From: "Tony McDonald" <[EMAIL PROTECTED]> To: "Zope List" <[EMAIL PROTECTED]> Sent: Friday, November 10, 2000 10:10 AM Subject: [Zope] Populating a :list variable from the results of a ZSQL method > Hi all, > Say I've got a form with this in it > > > number 1 > number 2 > number 3 > > > When this is put into an SQL database, the field 'options' is this (string) > > ['1', '2', '3'] or ['2', '3'] etc. > > When I get the data back from the database, 'options' comes back as a > string, and ... gives errors (basically, > it can't iterate over a string). > > I tried > > and then tried iterating over new_options, but the variable didn't exist... > > Has anyone got any solutions for this? > TIA > Tone > -- > Dr Tony McDonald, Assistant Director, FMCC, http://www.fmcc.org.uk/ > The Medical School, Newcastle University Tel: +44 191 222 5116 > A Zope list for UK HE/FE http://www.fmcc.org.uk/mailman/listinfo/zope > > ___ > Zope maillist - [EMAIL PROTECTED] > http://lists.zope.org/mailman/listinfo/zope > ** No cross posts or HTML encoding! ** > (Related lists - > http://lists.zope.org/mailman/listinfo/zope-announce > http://lists.zope.org/mailman/listinfo/zope-dev ) ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )
Re: [Zope] Populating a :list variable from the results of a ZSQL method
don't know about inside zope, but in plain python you could just do: new_options = list(options) perhaps an external method would cut it: return list(inputstring) -- Geir Bækholt web-developer/designer [EMAIL PROTECTED] http://www.funcom.com on Friday, November 10, 2000 Tony McDonald wrote : TM> Hi all, TM> Say I've got a form with this in it TM> TM> number 1 TM> number 2 TM> number 3 TM> TM> When this is put into an SQL database, the field 'options' is this (string) TM> ['1', '2', '3'] or ['2', '3'] etc. TM> When I get the data back from the database, 'options' comes back as a TM> string, and ... gives errors (basically, TM> it can't iterate over a string).

Nasty hack external method: def eval_options(self): return eval(self.REQUEST['options']) then you can do: ...but be careful with that external method, it could be used to do all sorts of bad things if it gets into the wrong hands. cheers, Chris ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )
[Zope] Populating a :list variable from the results of a ZSQL method
Hi all, Say I've got a form with this in it number 1 number 2 number 3 When this is put into an SQL database, the field 'options' is this (string) ['1', '2', '3'] or ['2', '3'] etc. When I get the data back from the database, 'options' comes back as a string, and ... gives errors (basically, it can't iterate over a string). I tried and then tried iterating over new_options, but the variable didn't exist... Has anyone got any solutions for this?
