Re: How to modify every element in a list all at once

You have to convert s.price.name to float (or .9 to a DecimalObject if the float-precision should be a problem). This should work: for s in s2: s.price.name = float(s.price.name) * .9 s.price.save() On Dec 16, 8:43 pm, Greg <[EMAIL PROTECTED]> wrote: > Shabda, > I added the

Re: How to modify every element in a list all at once

Shabda, I added the following code to my view: for s in s2: s.price.name *= s.price.name * .9 s.price.save() However, I now get the error: TypeError at /plush/chandra/antara/108/multi/ unsupported operand type(s) for *: 'Decimal' and 'float' On Dec 16,

Re: How to modify every element in a list all at once

How about for s in s2: s.price.name *= s.price.name * .9 s.price.save() You are getting a type error coz you can not mutlipy a Model object by float, and that is what s.price is. BTW s2[0].price * .9 would not have worked as well, because of the same reasons! On Dec 16, 11:08

Ned, I've added that code into my view. However, now I'm getting the following error: TypeError at /manu/coll/style/ unsupported operand type(s) for *=: 'Price' and 'float' I can't do a int(s.price), because then I get a 'Can't assign to function call' error. On Dec 15,
