Hello, I am building a small community site. I am building the login/signup system. I have a problem with the creation of new users on signup. I have a users zclass which is catalog aware. I used the job board tutorial to set it up (thanks! very useful documentation) When I a user signs up I search the catalog for their username, because I want to keep that unique. here is the code: Content-type: application/x-www-form-urlencoded <dtml-in Catalog> _root.feedback=sorry+name+taken <dtml-if sequence-end> </dtml-if sequence-end> <dtml-else> <dtml-var add_user_dtml> </dtml-in> This page is passed the variable "username". This works to catch existing usernames most of the time. However, in a few cases it will miss the fact that the name matches an existing name and go ahead to the <dtml-var add_user_dtml> page: <dtml-call "REQUEST.set('password', signuppassword)"> <dtml-call "REQUEST.set('username', username)"> <dtml-with "manage_addProduct['swatchuser']"> <dtml-call "swatchuser_add(_.None, _, NoRedir=1)"> </dtml-with> _root.feedback=success This code usually successfully adds a new user. However if the username is a duplicate (it shouldn't arrive at this page, but if it does) it will only successfully make a new zclass instance of the user if they are a single letter long!!!! Thus I get a user list that looks like this: max , yay , josh , mary , peter , john , ann , dog , cat , badger , fork , g , k , ww , u , u , u , u , u , b , u , erm , frog , erk , damn , erkf , this , bg , q , q , e , u , aname , j , j , j , j , j , j , j , j , j , j , amy , y , y , y So for single letter names the user signs up no matter whether someone else has that name or not. Which is not what I want. But the problem does not end their, else I would just not permit one letter name. For those who choose names of more than one letter, they may be told that they have successfulluy created a new user when they haven't. The times when this happens are usually if I haven't closed and opened the browser between sign-ups. However it happens seemingly randomly. I am calling all this code from a flash file in the same directory. I have the same thing working using zope and SQL no problem, but can't work it out with zcatalog. Unfortunately I need to! My first inuitions are that: 1: it has something to do with the pages being cached. 2: I am not updating the catalog properly, though I added the lines suggested in the job board tutorial to the add method of the zclass: <dtml-call reindex_object> Any hints will be appreciated... I think I may be reporting the same problem that is mentioned in: http://www.egroups.com/message/zope/44901 but I am not sure. thanks for your time josh on =========================== write: josh@futurefarmers.com read: www.futurefarmers.com read: www.crd.rca.ac.co.uk/~josh interrupt (i love it): (415) 552 2124 =============================
