[Zope] Data type coercion and records
*Now* I remember why I like Zope so much... I'm using the ":records" to marshall a complex hierarchical form, and I'm a little worried by this comment: http://www.zope.org/Members/Zen/howto/FormVariableTypes Note: Before creating a second record and adding an attribute, Zope gets the last record in the list and checks to see if that record has the attribute. If the first record doesn't have the attribute, it inserts the attribute and value instead of creating a new record. For example, if the user entered a name and age for Member #1 and only an email for Member #2, the list will have only one record. That record will contain the name and age attribute from Member #1 as well as the email attribute from Member #2. This isn't a problem for me, *except* sigh. I want to be able to tickbox certain fields to delete them, as well as alter the values in the textboxes to alter other fields. *BUT*, my HTML manual says that "CHECKBOX name/value pairs are only submitted to the server if the field is checked" So, I would expect this: dtml-var standard_html_header table dtml-if listdtml-in list tr tddtml-a;/td dtml-if btddtml-b;/td/dtml-if /tr /dtml-in/dtml-if /table formtable tr tdinput type="text" name="list.a:records" value="1a"/td tdinput type="checkbox" name="list.b:records" value="1b"/td /trtr tdinput type="text" name="list.a:records" value="2a"/td tdinput type="checkbox" name="list.b:records" value="2b"/td /trtr tdinput type="text" name="list.a:records" value="3a"/td tdinput type="checkbox" name="list.b:records" value="3b"/td /trtr tdinput type="text" name="list.a:records" value="4a"/td tdinput type="checkbox" name="list.b:records" value="4b"/td /trtr /table input type="submit" value="test" /form dtml-var standard_html_footer To read: 1a 2a 3a 4b 4a If you just ticked the 4th listbox. But it doesn't - it works as I "want" it to work, i.e. it reads: 1a 2a 3a 4a 4b Why? I'm glad this does, but as the saying goes, if you don't understand it, it can bite you when you least expect it. I've tested this under netscape 6 and IE5.0. I know I can work around it (set the value field of the checkbox to contain the information it's referring to) but I'm curious as to what's going on. I note that if you swap the textbox and checkbox around, it does indeed "break", and the delete is associated with the previous record as you'd expect. So - I suspect the behavious of "records" changed at some point? My question then becomes - does the HTML/HTTP spec guarantee that if I put the checkboxes *after* the textboxes, and Zope is marshalling the records in a useful fashion, this will always work on a conforming browser?

RE: [Zope] Help with getting started with Login Manager
Try this: http://www.zope.org/Members/jok/SQL_based_LoginManager Some extra pointers: Step 7: Customize the LoginManger instance to call the SQL methods You'll have this /root /folder /acl_users (LoginManager) /UserSource SQL_check_user SQL_get_password SQL_get_roles You're then supposed to add DTML Methods called userAuthenticate,userExists,userRoles *BUT* if you do this, you'll be locked out. Instead, add xuserAuthenticate xuserExists xuserRoles Edit test the DTML methods, then when you're sure they work, batch rename them (i.e. tick the boxes next to all three, then click rename). They'll be renamed as an atomic unit, and hopefully the LoginManager will work. It can be very frustrating to get going though - Once you've completed step 6, I recommend taking a copy of "folder" i.e. /root /folder (...etc...) /copy_of_folder (...etc...) If you break it, you can get back to /root, delete folder, copy "copy_of_folder" back to "folder" and not have to start from scratch. Very time saving.

Doh - my fault... RTFM I think... I think I misread the linked page.

[Zope] Form data type coercion syntax and javascript
Not a problem per-se, just a query - how are people dealing with things like
this:
dtml-var standard_html_header
FORM
SELECT MULTIPLE NAME="test"
/SELECT
SCRIPT LANGUAGE="JavaScript"
function populate(form) {
for (var i=0;i4;i++) {
form.test.options[i] = new Option("Red"+i,"color_red");
if (i == 0)
form.test.options[i].selected = true;
}
return false;
}
/SCRIPT
INPUT TYPE="BUTTON" onClick="populate(this.form)" VALUE="Fill in"
INPUT TYPE="SUBMIT" VALUE="Go"
/FORM
dtml-var standard_html_footer
If a user selects multiple values, of the dynamic list, Zope will coerce
them to a list when the form is input. *BUT*, if they select a single value,
it'll be a single string/integer. Normally, you'd do this:
SELECT NAME="test:list"
But how do you access it from JavaScript then? I'm doing this:
function populate(form) {
var list = form;
for (var j=0;jform.length;j++) {
if (form.elements[j].name == "test:list")
list = form.elements[j];
}
if (list == form)
return false;
for (var i=0;i4;i++) {
list.options[i] = new Option("Red"+i,"color_red");
if (i == 0)
list.options[i].selected = true;
}
return false;
}
Anything more elegant?

Phil

[Zope] RE: SQL Method, dtml-with and namespace weirdness
Heh. Oh well, you win some, you lose some! I appear to be losing some - maybe I should drink less caffine? I can work around the problem for the moment, but either: 1) I *totally* misunderstand how dtml-with works 2) It's misbehaving itself under some circumstances To recap: two SQL method returning [different] (name,domain) are used like this: dtml-in SQL_method1 Pdtml-name;/P - POINT A Pdtml-domain;/P dtml-in SQL_method2 Pdtml-name;/P- POINT B Pdtml-domain;/P dtml-with aFolder Pdtml-name;/P - POINT C Pdtml-domain;/P /dtml-with /dtml-in /dtml-in This will print: name1 domain1 name2 domain2 name1 domain1 That is: *inside* the dtml-with, the variables "name" and "domain" appear to be reset to their values in the *outer* dtml-in tag, not the innermost. This *only* happens if both SQL methods return variables named the same, and it *only* affects those two variables (so, I can work around it). Is this expected behaviour? Anyone who wants to see this problem can have Manager access to a test subtree I setup that reproduces the problem exactly. I realise it's far more likely that the problem lies with me - but what is the problem?

Hopefully that will get someone's attention. I have an SQL method that returns (name,domain,otherstuff) I have a DTML method (/root/host/show) that looks like this: dtml-comment 'name' and 'domain' are set to the primary hostname and domain at this point by whatever calls this DTML method POINT A /dtml-comment dtml-in "HDB_get_ip_aliases(ip=ip)" dtml-commentPOINT B/dtml-comment dtml-let name2=name domain2=domain dtml-with alias dtml-commentPOINT C/dtml-comment dtml-with "_.namespace(name=name2,domain=domain2)" dtml-commentPOINT D/dtml-comment dtml-var show /dtml-with /dtml-with /dtml-let /dtml-in The folder structure is: /root /alias show /host show At the points marked B and D, dtml-var name and dtml-var domain work fine, but at point B, name and domain have been reset to what they were at point A. Why? This is totally broken - I'm *this* far from downloading the servlet engine and giving up completely.

RE: [Zope] SQL Method, dtml-with and namespace weirdness
Sorry - I'm being unclear: the result is exactly the same either way i.e. the variables "name" and "domain" seem to be reset to the values from outside the dtml-in block when entering the dtml-with block. I'm wondering if it's a bug in the postgres DA, since I can't reproduce it with a quick gadfly test. I'm just going to try it out now. I'm using Zope 2.2.5, PoPy 2.0.1 from SourceForce, and ZPoPyDA-1.1-pre2 - I couldn't get any (potentially more stable) combination of PoPy or ZPoPyDA to work.

RE: [Zope] SQL Method, dtml-with and namespace weirdness
Ok, using Postgresql 7.0.2-2, PoPo 2.0.1, ZPoPyDA 1.1-pre2, Zope 2.2.5,
here's a reproducible scenario:
Create the following tables in your database:
create table bugtest1 (
name text,
domain text,
);
create table bugtest2 (
name text,
domain text,
refer text,
foreign key(refer) references bugtest1(name)
);
insert into bugtest1 values ('a','aa');
insert into bugtest1 values ('b','bb');
insert into bugtest1 values ('c','cc');
insert into bugtest2 values ('w','ww','a');
insert into bugtest2 values ('x','xx','a');
insert into bugtest2 values ('y','yy','a');
insert into bugtest2 values ('z','zz','a');
insert into bugtest2 values ('g','gg','b');
insert into bugtest2 values ('h','hh','b');
insert into bugtest2 values ('i','hh','b');
Create the following folder structure:
/root
dbconn (ZPoPyDA connection to whatever database you just put the tables
in)
index_html
get_host (Z SQL method)
get_alias (Z SQL method)
/alias
show
/host
show
/root/get_host
select * from bugtest1
/root/get_alias
select * from bugtest2
dtml-sqlgroup where
dtml-sqltest name column=refer type=string
/dtml-sqlgroup
/root/alias/show
TRTD/TDTDdtml-name;/TDTDdtml-domain;/TD/TR
/root/host/host
TRTDdtml-name;/TDTDdtml-domain;/TD/TR
/root/index_html:
1: dtml-var standard_html_header
2: TABLE
3: dtml-in get_host
4: dtml-with hostdtml-var show/dtml-with
5: dtml-in "get_alias(name=name)"
6: dtml-let name2=name
7: domain2=domain
8: dtml-with alias
9: TRTDPOINT
A/TDTDdtml-name;/TDTDdtml-domain;/TD/TR
10: TRTDPOINT
B/TDTDdtml-name2;/TDTDdtml-domain2;/TD/TR
11: dtml-var show
12: /dtml-with
13: TRTDPOINT C/TDTDdtml-name;/TDTDdtml-domain;/TD/TR
14: TRTDPOINT
D/TDTDdtml-name2;/TDTDdtml-domain2;/TD/TR
15: /dtml-let
16: /dtml-in
17: /dtml-in
18: /TABLE
19: dtml-var standard_html_footer
The output of all that is (a bit hard to read):
a aa
POINT A a aa
POINT B w ww
a aa
POINT C w ww
POINT D w ww
POINT A a aa
POINT B x xx
a aa
POINT C x xx
POINT D x xx
POINT A a aa
POINT B y yy
a aa
POINT C y yy
POINT D y yy
POINT A a aa
POINT B z zz
a aa
POINT C z zz
POINT D z zz
snipped for clarity
So: at point A, the "name" and "domain" variables have been overwritten with
the "name" and "domain" variables as they were on line 6/7, *BUT* name2 and
domain2 haven't been overwritten (point B). BUT, outside the dtml-with tab
(point C) "name" and "domain" are at their correct values.
So - given that the dtml-with tag "must" work, I'm clearly not understanding
*how* it works.

Phil

[Zope] Special-name of variables called 'name' or 'domain'
I've got some SQL method, and a folder structure, and am seeing some *very*
annoying results. Namely, dtml-with seems to cancel out variable
assignments from an enclosing dtml-in
/root
get_machine_hosts (SQL method)
get_host_aliases (SQL method)
show (dtml method)
/host
show (dtml method)
/alias
show (dtml method)
get_machine_hosts takes 'machineid' and returns 'name','domain','ip', e.g.
(for a 5-homed box) get_machine_hosts('535252'):
www,random.com,192.168.3.2
mail,hosting.com,192.168.3.3
news,random.com,192.168.3.4
sqldb,random.com,192.168.3.5
workstation,random.com,192.168.3.6
get_host_aliases takes 'ip' and returns 'name','domain' e.g.
get_host_aliases('192.168.3.3') [mail.random.com]:
'pop3','random.com'
'smtp','random.com'
'mail','random.com'
'imap','random.com'
But, I'm having problems with the 'in' and 'with' tags using the variable
'name'. The DTML methods are:
/root/show
dtml-in get_machine_hosts
dtml-with hostdtml-var show/dtml-with
/dtml-in
/root/host/show
TR
TDdtml-ip;/TD
TDdtml-name;/TD
TDdtml-domain;/TD
/TR
dtml-in get_host_aliases
dtml-commentPOINT A/dtml-with
dtml-with alias
dtml-commentPOINT B/dtml-with
dtml-var show
/dtml-with
/dtml-in
/root/alias/show
TR
TD/TD
TDdtml-name;/TD
TDdtml-domain;/TD
/TR
Now, assuming I'm looking at machineid 535252 (mail.random.com). I get this:
| 192.168.3.3 | mail | hosting.com |
| | mail | hosting.com |
| | mail | hosting.com |
| | mail | hosting.com |
| | mail | hosting.com |
That is, the variable 'name' and 'domain' aren't set correctly. But, if I
modify /root/host/show as follows:
TR
TDdtml-ip;/TD
TDdtml-name;/TD
TDdtml-domain;/TD
/TR
dtml-in get_host_aliases
dtml-commentPOINT A/dtml-with
TR
TD/TD
TDdtml-name;/TD
TDdtml-name;/TD
/TR
dtml-with alias
dtml-commentPOINT B/dtml-with
dtml-var show
/dtml-with
/dtml-in
I get:
| 192.168.3.3 | mail | hosting.com |
| | pop3 | random.com |
| | mail | hosting.com |
| | imap | random.com |
| | mail | hosting.com |
| | smtp | random.com |
| | mail | hosting.com |
| | webmail | random.com |
| | mail | hosting.com |
It would appear that the dtml-with alias tag wipes out the 'name' and
'domain' variables back to the values they had outside the dtml-in
get_host_aliases tag, so calling /root/alias/show gives wrong data. Very
odd. *BUT*, if I use 'aliasname' and 'aliasdomain' as the variable names,
everything is OK.
WTF?
While I'm at it, is dtml-with foldernamedtml-var dtmlmethod/dtml-with
really the best way to call a DTML method of a folder?
Regard,
Phil

RE: [Zope] LoginManager broken?
Ye gods...
Ok, steps I had to take to get LoginManager working
1) Create a folder, call it "test"
2) In that folder, add a LoginManager with a GenericUserSource, with *just*
"Basic Auth Login" selected. Leave the rest as defaults.
3) In the newly-created ACL-users folder, you'll find "forbiddenPage",
"loginForm" and "logoutForm" - you can delete loginForm.
Give logoutForm and forbiddenPage the "Manager" proxy role
4) In the UserSource folder/object underneath acl_users, add
a) A connection to the SQL database you'll be using
b) an SQL method "check_user" with a parameter "username", which does a
"select username from usertable where username = dtml-sqlvar username
type=string"
c) an SQL method "check_user" with parameters "username" and "password",
which does a "select username from usertable where username = dtml-sqlvar
username type=string and password = dtml-sqlvar password type=string"
d) an SQL method "get_roles" with a paramter "username" that does "select
groupname from group_members where username = dtml-sqlvar username
type=string" (or whatever is appropriate for your database)
5) Add the DTML methods WITH A DIFFERENT NAME - DON'T add
userAuthenticate,userExists,userRoles - add (say)
xuserAuthenticate,xuserExists,xuserRoles
a) xuserExists should read:
dtml-in "HDB_check_user(username=username)"
dtml-if "_['sequence-item'].username == username"
dtml-return "_.int('1')"
/dtml-if
/dtml-in
dtml-return "_.int('0')"
b) xuserAuthenticate should read:
dtml-in "HDB_check_password(username=username,password=password)"
dtml-if "_['sequence-item'].username == username"
dtml-return "_.int('1')"
/dtml-if
/dtml-in
dtml-return "_.int('0')"
c) xuserRoles should read
dtml-call "REQUEST.set('ret', '')"
dtml-in "HDB_get_roles(username=username)"
dtml-call "REQUEST.set('ret', ret+' '+groupname)"
/dtml-in
dtml-return ret
6) Give the "Manager" proxy role to the DTML methods, so they can access the
SQL methods you just created
7) Turn off acquisition of the permissions on the test folder, and be sure
to add read permissions to any local roles you're using
8) Make a copy of the test folder now, before it all goes wrong...
9) Batch rename the DTML method (e.g. s/x(.*)/$1/g in perl-speak) - if
you're lucky, it will work.
I have to say, I'm not hugely impressed...

Phil

RE: [Zope] XMLRPC accessing Zope DTML/SQL methods
sigh
Getting there. Note to the wise - when using PCGI and Apache, sometimes Zope
won't notice that you've edited an internal method source file... The cache
in Data.fs gets out-of-date.
Ok. So, I have this working:
def callSQLmethod(self, REQUEST):
s=self.sqlMethod(self, REQUEST)
y = []
for x in s:
y.append(x)
return str(y)
Called over XMLRPC, this gives me:
[r instance at 853ee30, r instance at 84f2810, r instance at 84f29f0,
r instance at 84b1528]
Fine, I can extract the result data later... How can I pass paramters to the
method without overwriting the REQUEST value - I need access to that, so I
can get environment variables, namely the SSL certificate subject name.

[Zope] XMLRPC accessing Zope DTML/SQL methods
I'm planning on using Zope as some middleware to an SQL database backend. Zope will implement the per-row ACL checking and such for the database application, and there are two clients - a simple web-based Zope frontend, and a larger standalone Java application. I'd like the Java app to communicate with Zope using XMLRPC, so that I can re-use the middleware portion, and take advantage of SSL'd HTTP, along with all the other bonuses such as not trusting the client :o) But: I'm having problems that indicate I don't understand how External Methods or the XMLRPC call support works. I have an SQL query method backed by a persistent DB connection. I want to call that method over XMLRPC remotely. How do I do that? Namely, how do I pass named arguments to the SQL method? Also, I did some simple External Method examples, and acquisition doesn't seem to work as advertised: This: def testf(self, REQUEST): return self.index_html() Gives an error "standard_html_header not found". What's going on?

[Zope] dtml-let and quoting(?) or forcing to string
All, I've just setup a test Zope installation. So far, very impressive. I'm using a Postgresql database containing a network hierarchy (basically, a table with a "network" column, and a "parentnet" column). I'm trying to display this with a tree view, using the following DTML: dtml-let network="0/0" dtml-tree id=network branches_expr="network_children(parentnet=network)" bdtml-var network/b dtml-var descr /dtml-tree /dtml-let Where the network "0/0" is the pseudo-parent of every other network. The problem is, python (or DTML, I don't know) interprets this as a divide by zero, and it fails. The other alternative "0.0.0.0/0" also fails: Expression (Python) Syntax error: invalid syntax , for tag dtml-let network="0.0.0.0/0", on line 15 of test_html (I'm doing all this through the web management interface). I'm not familiar with Python (yet - the book is on it's way) but in the command-line interpreter, this works fine: "0.0.0.0/0" '0.0.0.0/0' "0/0" '0/0' I need to cast the value to dtml-let to a string. How? I know how to do this in Perl/C/Java/Pascal, but it's not obvious to me why this isn't working.

[Zope] SQL trees...
Excellent. That answers that. I'm loath to ask this, since it's supposedly a FAQ, but I'm having trouble with the tree... Following: http://www.zope.org/Members/anthony/tree-coding-tricks I've got: dtml-let network="'0/0'" dtml-tree id=network branches_expr="network_children(parentnet=network)" bdtml-var network/b dtml-var descr /dtml-tree /dtml-let The SQL query is working - "test"ing network_children will give the correct hierarchy. However, the tree generated looks like this: 192.168/16 192.168/16 192.168/16 10/8 172.20/16 10/8 192.168/16 10/8 172.20/16 172.20/16 192.168/16 10/8 172.20/16 10/8 etc Basically, the tree only seems to ever contain the top-level (children of the root of the tree). The children of all the nodes is... another copy of the root top-level nodes! Whu?!? A search for several variations of "SQL tree" in all the relevant list/site archives didn't seem to help. Any ideas?

RE: [Zope] SQL trees...
Confirmed. Downgrading to 2.1.4 fixed it. How annoying... Thanks a lot!

Which Zope version do you use ? When I read your message I have a deja-vu: I encountered the same output when I use SQL based trees under Zope 2.1.6, it is a bug somewhere in the SQL method handling that appeared in 2.1.6 and is fixed in 2.2.0. Solution: switch back to 2.1.4 or forward to 2.2.0 or patch the existing 2.1.6 Philipp Auersperg (zwork) ___ 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 )
