[Zope-dev] Re: DTML block parsing - better then C/C++
This allowance for nested comments, as long as they are properly nested, is more then many laguages, such as C/C++, give you in the way of allowing nested comments - So I think its more then acceptable in its current form - good job! OK, I have developed a new patch that almost completely fixes this issue. In fact I am happier with it in general than my first patch. There is only one flaw, although you can nest comments inside of one another, and you can have any manner of broken dtml inside, if you open another comment tag inside it, it must be properly balanced or you will get a parse error. Here are some examples: ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )
[Zope-dev] ZSQL method - Can it 'resolve' a property value?
I have an index_html which runs queries that count the number of items in a
category and displays the number next to each category which is a link to
the SearchResults page that will pass the name of the property to the next
query. This is how I do the count part:
(dtml-in countAnnouncementsdtml-var announcements null=""/dtml-in)
I have a sql method for each count query and each uses a property (like
announcements above) that contains a list of numbers (i.e. Announcements
has: '001','002','003','004' )
So the query does a WHERE category IN ('001','002','003','004') statement by
resolving the property and getting the list of numbers. This part works
well.
Now,...
When I try to do the same thing on the SearchResults page, using a new sql
method, I cannot get the property to resolve. I try using an attribute of
the category for testing so it prompts for the category name when I test it.
I use the MULTIPLE attribute with a DTML-SQLTEST to produce the "WHERE IN"
type of query. I type in the name of the property that contains the list of
numbers and all I get for the query is: WHERE category =
('nameOfProperty')
This makes less sense as I am describing it, but it may be clear to someone.
Thanks

[Zope-dev] Mapping multiple IP addresses/domains to one Zope
My company has many sites which share some content. Each site uses a different IP address. I would like to bring all of these sites into one instance of Zope on an NT machine. I am looking at the possibility of either 1) running Zope behind IIS, or 2) running Zserver exclusively. Personally, I'd rather take the time in advance to learn how to do the whole thing in Zope, as I envision switching to a Linux server in the near future, and I believe that this would ease the migration. My question is this: How do I map different IP addresses/domains to different Zope folders? I am pretty new to Python (but learning fast!), so any snippets of sample code would be much obliged.

RE: [Zope-dev] Old to new registerClass
Im hacking around IEMethod and it uses an old style of class
initialisation
in the __init__.py along the lines of:
misc_ = { 'imagef':'foo','imageg':'goo', }
lang_= { 'en':'lang_en','sv':'lang_sv', }
I want to put this into a modern style product initialisation
(context.registerClass). Looking at this functions API it didn't become
readily apparent how I can pass in these values. This would be
nice to do so
I don't have any hacking of dtml to do. Has anyone done this / got any
advice?
Hi Andy - the modern product init doesn't currently provide
any special handling of misc_ (though it probably should in
the future to make registration an explicit operation). If
a misc_ mapping is found in your __init__.py by the product
initialization code, its items will be installed in the
misc_ object of the top-level application object. So you'll
want to do something like:
from Globals import ImageFile
misc_={'imagef': ImageFile('foo.gif', globals()),
'imageg': ImageFile('goo.gif', globals()),
}
When your product is initialized, the items in your misc_
will be installed in the application objects' misc_, and
you can refer to them thereafter in your dtml as:
dtml-var BASEPATH1/misc_/imagef
dtml-var BASEPATH1/misc_/imageg
etc. I don't know what 'lang_' does, so I'm not sure what
to advise you there...

Re: [Zope-dev] Mapping multiple IP addresses/domains to one Zope
Sorry, but I don't think I phrased my original question very well. I'll give it another try. What I'm trying to do is have Zope somehow map an IP address to a specific subfolder within the ZODB. For example, I've got one subfolder that should serve DOMAIN1.COM which is located at the IP address XXX.XXX.XXX.1, a second subfolder should serve DOMAIN2.COM which is located at the IP address XXX.XXX.XXX.2, etc... How can this be accomplished? If there is a way to do it behind IIS, that'd be great. SiteAccess could then take care of the conversion of the root domain name (I think). I hope I've cleared things up a bit.

I think that:
The "lang" Javascript variable is either set to "sv" or "en" so the script
include
file should look for either "lang_sv" or "lang_en".
The dictionary lang_ defined in __init__ isn't, as far as I can see, used
anywhere.
So you don't need to worry about it much.

Personally, I've found it more convenient to point all my domains to a single IP address, and let Zope (with help from SiteAccess) handle the rest. This has been easier, even though Zope is behind Apache, as Zope Access Rules are easier to create (IMO) than dealing with name or IP based virtual hosting under Apache.

Re: [Zope-dev] Local roles and security of ZClass instances inSpecialists
Hi Steve, This is a nice idea... but I can't get it to work. it works fine when changing properties: WHEN OBJECT CHANGED CALL self.checkForPermission(REQUEST) But is ignored for accessing properties: WITH self.checkForPermission(REQUEST) COMPUTE spam='eggs' simply fails to set spam if checkForPermission raises an exception, because ZPatterns catches all exceptions in COMPUTE clauses (I never understood the point of this, BTW. It just gets in the way of debugging. Wouldn't catching just AttributeError and KeyError be enough?) and the exception gets dumped to the console. Which could actually be considered to work, because the method doing the access will fail... but that would be ugly and definitely not what I want. Also, I want a solution that would work regardless of the storage method - I don't think this one won't work for ZODB storage. In a Rack using persistent storage and having a property 'spam', the SkinScript clause: WITH self COMPUTE spam='eggs' will be ignored. So the SkinScript can be used to control access only if it's already being used to load the properties. Which all comes down to having to do the security checks in all the methods that access the object :-( Unless you can show me something I missed? Steve Spicklemire wrote: Hi Itai, I'm sure there's something clever you could do here with an attribute provider for you user object that supplied __roles__ dynamically somehow, but I'd need to think about that more... one easy way to limit who can see different stuff is to use a wrapper around your access methods (e.g., SQL queries) that checks for security: e.g., WITH [ QUERY ] LookupAttributesAndCheckForPermission(REQUEST) COMPUTE foo, bar, baz where LookupAttributesAndCheckForPermission get's everything it needs out of the REQUEST.
