I want to take data from a form and send it to a dtml method. this is dtml-doc-doc <form action="method1"> <input type = "checkbox" value="true"> <input type="text" name="string"> <input type="submit" value="submit"> what is my dtml method going to look like? I want to set parent folder property equal to string. and I want to build a new page based upon the values from radio buttons and check boxes. Or even submit a string to a query based on the form data. I have having trouble with the dtml method syntax. I am thinking <dtml-let-let property = string> </dtml-let-let-let> <dtml-call-call dbquery(string)> etc. So in method1 how do I set <dtml-var-var var1> = string from the form. also how do I set the parent folder property <dtml-var-var property> = string. thanks technology(a)mylinuxisp.com

Help: DTML lookup problem (subfolder specialization)
by Robb Shecter 15 Feb '00

15 Feb '00

Hi, I want to have a logo at the top of each page, so what I've done is reference a "logo" method from my "header" method. Subfolders should be able to redefine a new "logo" method if they want to. This only works, though, as long as there's a dtml_index in the subfolder. If, though, the subfolder doesn't define one, and a parent's dtml_index is found, then the *parent's* "logo" is also used, not the one in the child folder. Is it possible to do what I want? Here's a hierarchy view: PARENT: logo index_html (Calls header which ref's logo) SUBFOLDER: logo ...This set up is not working for me. Is there some way to make it work? That is, when viewing the subfolder, it's logo would get found and used? Thanks, Robb

Re: [Zope] why use eGroups for the list archives?
by alan runyan 15 Feb '00

15 Feb '00

eGroups times out every other time I use it --I search, server times out. I search again, it works. I dont know of a better way, but i tend to spend lots of time in the archives looking for answers and it is painful :( anyone search for something get results, type another phrase in and get, "We were unable to find any results for your query. Reason: No group specified." which makes me go back to Zope search form on zope.org each time to make a search how about NNTP? not linked to usenet. something where client side tools are more useful (NT by day, linux by night) to browse topics/threads more efficiently. ideally it would look really swank to have all messages catalogued and served by Zope. ~alan

PARENTS
by Pedro Silva 15 Feb '00

15 Feb '00

Hi there, Idon't understand very well the PARENTS, but I know that I have to use them in my case. What I want to do is, something like the following example: Group1 Sub1 ==> link to msg Sub2 ==> link to msg Group2 Sub1 ==> link to msg Sub2 ==> link to msg When I click in one of these links, it will show the msg page. In here I have to know which link was clicked to can display the information of that link. Something like this: Group1 - Sub1 Messages: 1 - message #1 2 - message #2 Or Group1 - Sub2 Messages: 1 - message #1 2 - message #2 One of this examples will show up, in the first if we had clicked in Group1 Sub1 link and in the second, if we had clicked in Group1 Sub2. And so on. To do this I know that I will have to use the parents to know which link was clicked, but I don't know how. Can anyone help me? Please send you answers to: psilva(a)ruido-visual.pt Thanks, Pedro

Re: [Zope] Authenticating many users to manage only their own folders?
by Phil Harris 14 Feb '00

14 Feb '00

Darran, I would create the users in a root level UserFolder and then assign the user local roles within their own forlder. This can be done programmatically, something like: def add_User(self, username=None,password=None,confirm=None,domains=[],roles=[]): ###### # let's create the user ###### self.acl_users._doAddUser(name=username,password=password,domains=domains,ro les=roles) ###### # now create the home directory for this member ###### self.members.manage_addFolder(id=username,title='',createPublic=0,createUser F=0) title="%s's Homepage" % username s="""<dtml-var standard_html_header> <h2><dtml-var title_or_id></h2> <p>This is the default page created for a Member, it has very little content, as you can see. <p>To see a better example of how Zope works look at the <a href="&dtml-SCRIPT_NAME;/zGold/QuickStart">QuickStart</a> documentation. <p>Also see the <a href="&dtml-SCRIPT_NAME;/zGold/Example">XML examples</a>. <p>Most of all have fun!. <dtml-var standard_html_footer>""" eval("self.members.%s.manage_addDTMLDocument(id='index_html',title=title,fil e=s)" % username) ###### # now set them as manager of this domain ###### eval("self.members.%s.manage_addLocalRoles(userid='%s',roles=['Manager'])" % (username,username)) return " " You might want to investigate alternatives to the eval bits though, could be a bit of a security problem.

Any exposed list or dict needs a sharp examination. > > Cheers, > > Evan @ digicool Hmm, maybe we need to wrap any "global" dictionary / list in a "readonly decorator", and let lists/dictionaries declared locally be the "normal" ones. Actually, looking at the stock Python UserDict, we could just wrap any dictionary exposed inside a PythonMethod (DTML, too?) in a UserDict: its __init__() method already makes a (shallow) copy of the dictionary passed to it. Any key assignments done would thus be localized (although mutable values inside the source dictionary could still be munged).

SQL Question - GUF related
by James W. Howe 14 Feb '00

14 Feb '00

I'm moving forward in working with the GenericUserFolder. I'm adding a database interface to pull user names out of a database table. I have created an MS Access database with a couple of users. I have created an ODBC connection object in my acl_users folder and tested it to make sure it works. I then created a SQL method called "getUserList()" which should answer a collection of user ids. Using the Test feature, I get back expected results. I tried to change the userList method defined for my GenericUserFolder to use these results. Basically I do the following: <dtml-return "getUserList()"> However, when I click on the UserList tab, I get no names. I've tested the SQLmethod and it works fine. I also created another method, called testList which just contains the following: jwh jorge If I use testList in my userList method, I get the expected results. I'm sure that I'm doing something stupid, but for the life of me I can't figure out why the userList method fails when I access a SQLMethod but not when I access a DTMLMethod. Another thing, if I try to "view" my userList method when it references the SQLMethod, I get a resource not found error, but when I view the method when it references a DTMLMethod, I get the two names. Any ideas on what is going on here? I'm assuming it has something to do with the way the SQLMethod answers its results? Thanks. James W.
