It is not clear exactly how you are using the Page Template. Typically
the page would have an img tag that calls a python script that calls the
External Method. Remember the web browser fetches the image separately
after the html has been received - so your img tag might look like this:
img src=getImage?filename=whatever ... and your getImage python
script would look like this:
(type, encoding) = context.getMimeType(context.REQUEST.filename)
context.REQUEST.RESPONSE.setHeader('Content-Type', type)
context.REQUEST.RESPONSE.setHeader('Content-Disposition', 'inline;

where getDocumentCall is the name of your External Method that calls the
getDocument External Method and getMimeType is another External Method
that looks like this:
import mimetypes
def getMimeType(filename):
return mimetypes.guess_type(filename)
and your own external method would look like this:
##parameters=filename
def getDocument(filename):
fname = '/mnt/'+filename;
input = open(fname,'r')
content = input.read( )
input.close( )
return content
At the moment you seem to have skipped a step.

Re: [Zope] segregated users
It is possible, I have done something similar. My solution involves giving users a Local Role in a folder to which access is to be granted. I built a small utility (with ZClasses - doh) to make it easy for the Administrators to add users from a database. Cliff Tim Evans wrote: I apologize if this issue is something that has been discussed before, but I searched the archives to no avail. I'm evaluating zope for a project, and I have some questions regarding the extensibility of the user security model. The company I work for would like to provide documents to clients via the web, and only allow one particular client (or group of users from the same client) access to those documents. I don't want any user to be able to detect the presence of any other user. I essentially want several sites, one for each client, with a group of administrative users responsible for maintaining these sites and publishing content to all of them. What this would require is a group of administrators that can see all sites, as well as restricted users with privileges to exactly one site. I'd also like to avoid having a role for each site, as that could get ugly for almost 1000 clients. It would also be great if we could designate a user to administer only one site, so that they could only publish data to one client. I guess I want zope-level users and application-level users. Is this something that sane people do? I don't really need a step-by-step, just a yes, that is possible or a no, you're an idiot before I start digging in to try and do it.

Re: [Zope] Re: login page problem
I am not sure I have much to add. I have been concerned about your product architecture and unusual login procedure, but that is really non of my business. Some of what you say below is inconsistent: One problem that concerns next query is that it took only one table for user details whereas i had one more table for district. ... userdetail table is linked using this district code. From this, and what you said previously, I presume you have login working but for only the half of the users in one of the two User tables. I already suggested alternative ways of handling this. If your folders are going to be Districts consider giving users who need to fill out forms in one District a Local Role in that District, and users who need access to many districts a Local Role in the Districts parent folder. This correspondence is too long for anyone else to follow. Next time, may I suggest come back to the list with a new question in a new thread.

If you are going to use Plone I can't offer advice - I have looked at Plone on three separate occasions, and recently read The Definitive Guide to Plone, and have stil decided not to use it. I only say this to make it clear that many applications are built without CMS and Plone. I had no idea about this. i knew that zope acts as a app server and plone is the front end tool. In fact I'm building the store's site as a plone site in zope. As a matter of fact i've not done much specific in plone . just built 2 tabpanes. I configured the exUserFolder using the mysql database and as expected it built up a seperate login system. so i believe it'll work on itself without plone. One problem that concerns next query is that it took only one table for user details whereas i had one more table for district. Two separate tables with User information is awkward! The user folders I know of expect user information to come from one source. So you either have to create two folders, each with its own acl_users (provided by one of the User Folder Products), or you have to hack the User Folder product to put in a Union select statement in place of a simple Select. d quarters. let me explain the login page flow. a dropdown list of districts is available on load. on selecting a district the page reloads and the available users are listed in 2nd dropdown list. after selecting the user the password is to be given. So that way i need both the 'district' and the 'userdetail' table. actually the district table has district code ,name and other stores related nfo. userdetail table is linked using this district code. You have not said whether the people in the different districts do completely different things with different forms, or identical things but specifying the district. If the former then it is no big deal to create the folders manually, although it can be done programmtically. You could set a Local Role equal to the district name and get that role for users from the database. That way, users can only enter their own district folder. If the latter, then you could retrieve the Username and District from the User object for use in the forms (include the District as a role). users are of different level like store-in-charge, sys mgmt group, vendors and normal users. they are in all the districts. so depending on the user level diffrent set of menu page are to be generated ie. users of same level in diferent districts do same thing. In earlier ASP version I handled this in the login page handler ASP page and wanted to use the same logic here. district shouldn't be the user role , 'userlevel' will act as user role here. but the folders would be districtwise, I suppose. honestly I'm little bogged out by the exuserFolder feature, its using Dtml all the way and I'm sticking to ZPTs and script pythons. Try working on the rest of your application to build up ZPT and Python experience. As I said, managing users is tricky. Also, be aware that Zope experts advise developers to produce file system based Products. There are lots of simple Products that you can use and browse the code to see how they work. Cliff I completely understand this. but the problem remains the same . how do i customise these products acccording to my needs. hope this helps you in helping me. waiting for your reply. ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )

kindly bear for that.
lets revise,

district table ( district_code, distname, location ...)
userdetail (username ,password, empcode ,district_code ,ulevel ...)
user to district is n:1 mapping.
So I need to have both these tables info in the XUF.
Anyway, i'm trying cookies as advised.
tell me how do i set a request var in my python script.
i tried :
request.set('invalid','1')
return context.REQUEST.RESPONSE.redirect('index_html') // back to login page
I'm using 'invalid' hidden field to display the 'login failure' msg.
body tal:define =valtest request/form/invalid|nothing// define

Re: [Zope] Does anyone care whether we deprecate ZClasses?
Is this a kafkanian situation? Are really core developers asking the community to kick a used Zope's feature, saying it's because it's hard to maintain it, and simultaneously to say it's code 'unmaintained and untouched since ages'? Folks, you didn't need to ask for the aproval of people who didn't make it with that feature. You just do it. You're the ones that create the knots and know for sure where they are, and if you aren't in the mood anymore just give the thing over. :) As of your remarks, Andreas, I understand your point. People who care should take over. Sounds fair. Just please don't mean that we who say yes to a Jim's question are guilty of not letting Zope to move on, because Zope is moving to X3, not to 2.X+five, and definitely not to Archetypes, a CMF subject. As for ZC, IMHO the issue should be treated as a matter of understanding the market rather than achieving a milestone. You created stuff that works in some way or another that people embraced.

If there are serious problems in further releases with ZClasses holding up a new release we should kick them.

I've tryed to do this as following:
...
from Products.ExternalMethod import ExternalMethod
class Container(Folder):
meta_type ='Container'
def __init__(self, id, title):
self.id = id
self.title = title
index_html = DTMLFile(dtml/indexContainer, globals())
search = PythonScript(id='search')
searchService=ExternalMethod('searchService','searchService','search','search')
.
The id and title are searchService . The module and function name
are 'search' and they are located in Extensions directory in my
Container Product.
The following error is printed:

Re: [Zope] Problem with Z Psycopg
Jeff Gentry wrote: On Tue, 5 Apr 2005, Dieter Maurer wrote: Usually, this means that the postgres server process died... I did run into something recently where the local firewall was killing the connection to the DB server due to a timeout, so one of the local admin types wrote a small zsql method that gets hit by a cronjob about once an hour or so. Granted the end effect is the same (zope thinks that the DB server has died) but in this case it was the connection itself. Yeah, I think Jeff nailed it. I had FreeBSD's IPFilter set to drop idle states after an hour. Turns out FBSD by default does TCP keepalive, but only after 2 idle hours. I changed the net.inet.tcp.keepidle sysctl to lower it to a half-hour, so it now gooses the firewall often enough that I haven't seen a dropped connection since then. Looking back at the pgsql logs, I think I've always had this problem, but just didn't realize it until I tried a new ZPsycopgDA that lacked the auto-reconnect feature. Even though tweaking TCP fixed the problem, I think it'd still be good if ZPsycopgDA was able to auto-reconnect, because you could lose connections for other reasons - such as restarting postgres - and it'd be nice to not have to go and restart Zope too. (I think it's kind of funny that I didn't find out about my TCP problem until ZPsycopgDA failed to auto-reconnect, and I wouldn't have found out so soon about ZPsycopgDA not auto-reconnecting if I didn't have the TCP problem :) Barry ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )

kindly bear for that.
lets revise,
In my login page I've two tables used district and userdetail.
district table ( district_code, distname, location ...)
userdetail (username ,password, empcode ,district_code ,ulevel ...)
user to district is n:1 mapping.
So I need to have both these tables info in the XUF.
Anyway, i'm trying cookies as advised.
tell me how do i set a request var in my python script.
i tried :
request.set('invalid','1')
return context.REQUEST.RESPONSE.redirect('index_html') // back to login page
I'm using 'invalid' hidden field to display the 'login failure' msg.
body tal:define =valtest request/form/invalid|nothing// define
b tal:condition=valtestInvalid Password .Re Type/b//msg
nothing is happening

Do not worry too much! Jim proposed to keep ZClasses alive until (at least) Zope 2.10. And he asks whether there is enough interest to keep them longer... If the Zope 2 releases progress in the same speed seen recently, then Zope 2.10 will come in 4 to 6 years. That's a lot of time. Of course, it is planned that future release cycles are much shorter (one release every 6 months) but I do not yet buy that this will indeed happen. Almost all releases were planned much earlier than they happened. And, we can keep ZClasses alive, at least until the next major Persistency shakeup (after Jim made them working again for the current Persistency shakeup) -- even when they are no longer in the core. In fact, I have had ten times more problems with Archetypes (which I use now) than with ZClasses (which I used formerly). It is true (and sad) that there are no unit tests for ZClasses but ZClasses just broke twice in the past across releases and the community quickly found workarounds. These fixes were found much faster than those for the security problems which were introduced from time to time into Zope through security shakeups -- despite the fact that there are unit tests for the security subsystem. Thus, the right approach (in my view) is that all users of ZClasses tell Jim, that ZClasses are used and interesting. ZClasses may nevertheless get deprecated but probably kept longer then Zope 2.10 unless they cause major problems. For new projects, you should investigate the new options. Product development will get much simpler with Zope3 technology (and its schemas and views). Currently, there is no TTW (Through The Web) development in Zope3 land, but that is planned. In about 2 to 4 years, we may have new ZClass like functionality implemented with Zope3 technology. And I am quite confident that the old ZClasses will live til then...

I've used Zope for 2 years, and I can't help others program high-level Python OOP tools/platform resources in a propriety web content management server.

[Zope] Does anyone care whether we deprecate Your Favourite Part of Zope
I think people on this list need to realize that eventually, the direction of any significantly large Open Source project is hijacked by the relatively small number of people actually doing the work. The reasons for this are many-fold, but, normally come down to a lack of communication between the developers and the users, which is realized in a lack of understanding by the developers of what the users want. This for the most part isn't generally a problem, until, the developers start to do things for the user's own good, like remove features that are kludgey, or a hack, or insert some other reason, which generally means either noone wants to work on it, or some other change caused it to break, and noone wants to fix it. Now to the credit of the Zope guys, they actually poll the users to find out, rather than just announce the demise of something. However, in general once you add a feature, you can be guaranteed, that somewhere, someone is using it, so removing it will always cause a problem. So there will always be an uproar when you poll. You're never going to be able to reduce the feature set between point releases without upsetting some group of people. So why don't we stop all this nonsense now, and just agree, that you're never going to do that d8) You have Zope 3 to remove all the stuff you hate d8) In my opinion if you change something, it's your responsibility to fix the resulting breakage. That's part of your responsibiliity to the rest of the community (i.e. the [mostly non-paying] customers). If you don't think you have this responsibility to us, then you should work on your own version of Zope, where you're not impacting anyone else.

It depends on whether people choose to test their application during the beta cycle or during the release cycle. This will be a *big* change. Possibly, this will be bigger than the change from 2.7 to 2.8. I do think it will provide significant benefits that justify the pain.

That will work, and I don't see a need to deprecate it. Eventually, though, I expect products to migrate to ZCML-based security declarations. Is this a general trend for Zope 2? I'd rather see Zope 2 kinda avoid ZCML if possible. It's just one of those personal preference things, I suppose, but I know I'm not the only one who isn't that enamored of the ZCML approach. I actually like having the declarations all in the python code like it is in Zope 2. I'd like to see the declarative style that Zope 2 move to using decorators. I was sitting in a presentation at PyCon talking about MetaClasses, and I finally *got* them. I realised that the security declarations in Zope 2 are a perfect fit for metaclasses and decorators. If only I had the time to actually implement this dream ;) Note that this all comes from the perspective of someone whose only exposure to Zope 3 has been through two sprints. I've not actually tried to develop any sort of application using it. My day job is very firmly fixed in Zope 2, and isn't likely to change for a long time. So I'm definitely speaking from ignorance of real-world application development in Zope 3.
