Hi, Can somebody provide me informational links of documents which present the benefits and non-benefits of both DB? eg. When to use one and when not to use one? Thanks, Tom.

Adding roles in 2.3b2 and CVS
by Phil Harris 22 Jan '01

22 Jan '01

All, Has anyone else had trouble adding roles when using 2.3b2 and CVS versions of Zope? There seems to be a consistent bug in <ZopeDIR>/lib/python/AccessControl/role.py. The calls to self.manage_access(self,REQUEST) seem to have too many arguments, am I right? I 'fixed' my version of the file ut someone with more nouse will need to check this out. Would this be better reported in the collector? Phil phil.harris(a)zope.co.uk

form question
by Oliver Vecernik 22 Jan '01

22 Jan '01

Hi all, I'm a newbie to Zope and Python. Nevertheless I'd like to start with it. I'm designing an application gathering data with forms. Navigation should be done with Prev and Next buttons. As long as I'm not leaving the form data should be entered, processed and the *same* or another form should be displayed, depending on input of the user. So far I'm able to gather data, store them in a database, but can anybody give me a clue or point me to some docs how to control which form should be displayed next? It should depend on users input of let's say a text field. Oliver

Well, bad _technically_, or bad _evil_? <G> It does have the sole advantage you can pull a portion of your tree, and some people have had Data.fs problems (not me thankfully). But in general I'd guess backing up Data.fs to be the best way. How does it copy with non-atomicity of disk writes?

That's actually a really bad way to back up Zope :-S Copying data.fs is much more reliable and _much_ less strenuous on your server, especially if it's a big Data.fs cheers, Chris _______________________________________________ Zope maillist - Zope(a)zope.org 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 )

This certainly isn't *efficient*, but it works: wget -http-user=usename -http-pass=password http://your.site.com/Zope/path/to/wherever/manage_exportObject?download%3Ain t=1 Will get you a .zexp of "/path/to/wherever", whereas: wget <blah> http://your.site.com/Zope/manage_exportObject?download%3Aint=1&toxml=Y Will get you an XML export of your entire site.

Hi all What is the best way to backup Zope's database whithout stopping Zope? When I use backup, it just says that the file is in use and cannot be backed up. What I have done so far is to copy the file in explorer and back that up - but it feels kludgey and I'm not sure if I get the database in a state that is safe.

Zope, database field formats, output format of queries
by Michael Schmidt 22 Jan '01

22 Jan '01

Hi, having searched through zope's website at the weekend and gone through the mailinglist archive I did not find stuff regarding the below in FAQs or HOWTOs. The general idea behind zope and the features of it are wonderful. I'm thinking of one application and would like to know: Can you create fields in a zope based database where you force the fields to accept e.g. only letters "M" or "W" or any other other combination of your choice? Can you setup database fields with a format e.g. of "99999/99/9" where all 9s mean numeric input 0-9 and the slashs are always put at their fixed positions by the software when the field is displayed for input? Can you setup database fields with a date format e.g. DD/MM/YYYY or MM/YYYY which *force* the user to input values in that format? Can you output queries of databases in a format you can choose yourself, that the output fields may be incorporated into serial letters to be run by/through text-processing or office systems? Would be fine to get your responses. I appreciate your feedback. Have a nice day Michael -- Michael Schmidt mschmidt(a)fh-koblenz.de MIRROR OF Ghostscript * X-Windows X11 * DJGPP * and more...

[python] creating variable names by adding 2 strings?
by Lee 22 Jan '01

22 Jan '01

Hi there, I'm creating variables in python but I am having trouble creating them when they're *named* using other variables. Here's an example; while (p!=0): p+`p`= string.replace(component[control], ",", "") # e.g. I want 'p1 = string.replace.blah...' p=p-1 control=control+1 ==> SyntaxError: can't assign to operator :( I've tried various things but I cannot find a solution. I've got a nasty feeling that it's not possible... If someone could confirm this or hopefully, tell me how to do it I would be_extremely_grateful. Thanks, Lee (crossing his fingers)

Is the source code to www.zope.org available somewhere? It would certainly be an interesting example of how to build a large web site with Zope.

Adding to an XMLDocument through web forms
by Ian Campbell 22 Jan '01

22 Jan '01

Hi, I`m looking for a way to give a user the ability to add new data to an XMLDocument through web forms, does anyone have experience of this or would be able to point me in the direction of an example or howto? I have a file similar to: <channel> <event> ... </event> <announcement> ... </announcement> </channel> So i`d have two web forms, one to add a new <event> and another to add an <announcement>, taking the data from a form is obviously simple but adding this to my XMLDocument has stumped me. Any help would be appreciated. Ian
