Creating a directory using Zcatalog and either tree or some other method
by Chris Muldrow 07 Mar '01

07 Mar '01

OK, here goes another convoluted question: I've got news stories in a Zcatalog. I want to build a directory of said stories. Each story contains multiple properties, with the key properties being title, CreateDate (the date the story was created), Category (Sports, Local, Features, etc.) and Locality (Stafford, Spotsylvania, etc.) I want to build this directory so it displays all of today's stories. I want to display them under headers using the following criteria: If Category=='Local', then print a header for the localities and sort them. Otherwise, print a header for the categories. Here's how it should look: Spotsylvania (This is the locality) Headline 1 Headline 2 Headline 3 (all of these stories have category "Local") Stafford Headline 1 Headline 2 Headline 3 (all of these stories have category "Local") Sports (This is the category) Headline 1 Headline 2 Features (This is the category) Headline 1 Headline 2 This code pulls out all of my stories for today's date. My problem is sorting them under the category headers: <dtml-in expr="Catalog(CreateDate=[ZopeTime()-1,ZopeTime()], CreateDate_usage='range:min:max')"> -- Chris Muldrow, muldrow(a)mac.com

Hi there, I'm trying to build a "day" dropdown list with the current day as the selected value. However the if clause wont work for days with a daynumber below 10 since in my example below the DateTime.dd will return 07 and my sequence-item has the value of 7. Suggestions anyone please. Fred <dtml-let Date="_.DateTime()"> <dtml-var expr="_.DateTime.dd(Date)"> <SELECT name="day_fld"> <dtml-in expr="_.range(1,32,1)"> <dtml-if expr="_['sequence-item'] == _.DateTime.dd(Date)"> <OPTION SELECTED value='<dtml-var sequence-item fmt="%02d" >'> <dtml-var sequence-item fmt="%02d" > </OPTION> <dtml-else> <OPTION value='<dtml-var sequence-item fmt="%02d">'> <dtml-var sequence-item fmt="%02d"> </OPTION> </dtml-if> </dtml-in> </SELECT> </dtml-let>

ZCatalog and ExtFile
by Andrew Williams 07 Mar '01

07 Mar '01

>From what I've read and understood, ZCatalog aware objects automatically update the catalog whenever they are added/deleted/changed. However, ExtFile does not update ZCatalog whenever I add another ExtFile object to the ZODB. I've checked the ExtFile code, and indeed, ExtFile inherits from Products.ZCatalog.CatalogAwareness, CatalogAware. I continued to look at the ExtFile code, and discovered that ExtFile overides many of the methods in CatalogAware (manage_afterAdd, manage_beforeDelete, etc), but doesn't contain any of the code in the methods of CatalogAware. I added the code from the CatalogAware methods, but my ZCatalog still does not update whenever an ExtFile object is added/deleted, etc. Am I missing something here, or am I completely off base with my thinking? Has anyone gotten the ExtFile product to be ZCatalog aware? Thanks for any help, Andrew Williams _________________________________________________________________ Get your FREE download of MSN Explorer at http://explorer.msn.com

HowTo configure premissions for LoginManager?
by Johan Carlsson 07 Mar '01

07 Mar '01

I have just setup a LoginManager following the LoginManager with SQL and Skinscripts by dlpierson. Now I'm thinking about how to setup security for my LoginManager. At the moment it's very open for anyone who has DTML permissions on my lab server. Not so great. LoginManager has premissions set to: Manager --- All Anonymous --- "Access contents information", "Use Database Methods" "Acquire permission settings?" --- None Now, this is needed to allow Anonymous user to login. But it also makes it possible for a Anonymous to access the following DTML Method in the root folder: <dtml-var standard_html_header> <pre> <b>test.acl_users.getUser('a').username</b> <dtml-with test> <dtml-with acl_users> getUser('c').username: <dtml-var "getUser('c').username"> getUser('c').password: <dtml-var "getUser('c').password"> getUser('c').getRoles: <dtml-var "getUser('c').getRoles()"> </dtml-with> </dtml-with> </pre> <pre> <b>dtml-in "sql_getUserFor(username='c')"</b> <dtml-with test> <dtml-with acl_users> <dtml-in "sql_getUserFor(username='c')"> username: <dtml-var username> password: <dtml-var password> </dtml-in> </dtml-with> </dtml-with> <dtml-var standard_html_footer> Which returns (where there is a user named 'c'): test.acl_users.getUser('a').username getUser('c').username: c getUser('c').password: d getUser('c').getRoles: ['test'] dtml-in "sql_getUserFor(username='c')" username: c password: d Now the question is how (and where) should I configure permissions so LoginManager gets secured? TIA/Johan Carlsson

Re: [Zope] Solved: How to get the url without the domain...
by Ausum 07 Mar '01

07 Mar '01

No, Evan. I didn't and now I'm glad you've mentioned it. From now on I'll look for documentation within the methods at the python modules. The answer was at Application.py all the time. :) Now about urls parsed through getpath and <dtml-in>, and after looking at its correspondant Zcatalog.py module (where it isn't defined a "relative" argument), the remaining question would be this: Is there a short way to do the same thing, when using Zcatalog? Thanks a lot, Ausum >I missed the start of the thread; Have you tried "absolute_url(1)"? >Cheers, >Evan @ digicool & 4-am

Hi all, I'd like to know if STXDocument 1. 2 by Tres Seaver still needs Renderable ZClass or if DC added it in the 2.3.0 version. ... or if there is something even newer about Structured text docs! Thanks! Michele

something wrong with my uploaded images
by Hans de Wit 07 Mar '01

07 Mar '01

Hello, When i add images "by hand", the images are perfect. However uploading them with the following dtml doesn't work. The result is an object, but when i view it, there is a cross (like this image is not found). There are not enough bytes in the image object either. I checked the variables foto_id, foto_file and foto_title with an <dtml-var foto_id> etc. They seem to be allright. The manage_delObjects also works fine. What i am doing wrong? any hints appreciated <dtml-with expr="PARENTS[1].fotos"> <dtml-if expr="_.hasattr(this(),foto_id)"> <dtml-call expr="manage_delObjects(foto_id)"> </dtml-if> <dtml-call expr="manage_addImage(id=foto_id,file=foto_file,title=foto_title)"> </dtml-with> <dtml-call "RESPONSE.redirect(HTTP_REFERER)"> Met vriendelijke groeten, Hans de Wit h.de.wit(a)scp.nl
