Product seeking products: how?
by Terry Hancock 07 Jun '02

07 Jun '02

Hi all, I need to create a plugin architecture for a product I'm developing, since I want to encourage third-party contributions, and define a clean way for them to work together. Given that Zope already has a nice plugin architecture, AKA Products, it seems like the most logical solution is to use that. Thus, my plugins would just be Zope products which implement a certain interface. But it is unclear to me how best to go about finding them. It seems like the most plug-n-play way for this to work would be for my product to collect all the plugins when Zope restarts -- but there are some problems, such as how to run code after all the other products have loaded. Is there any example code I should be looking at to do this (i.e. other products that behave like this)? Thanks, Terry -- ------------------------------------------------------ Terry Hancock hancock(a)anansispaceworks.com Anansi Spaceworks http://www.anansispaceworks.com ------------------------------------------------------

nested <dtml-in ...> statements breaking
by Donald Braman 07 Jun '02

07 Jun '02

I have nested queries using dtml-in statements. The outer query performs a broad query based on a number of variables and returns a number of variables for several records. The inner query performs a dtml-sqltest on one of the variables returned and returns another set of variables. (Or at least it is supposed to.) The only variable that two queries share is the variable on which the inner query performs the dtml-sqltest. The inner query gives me a key error, asking for a variable supplied by the outer query. Strangely, the inner query works when nested within a query that returns a single record using the same dtml-sqltest as the inner query. Any pointers on how to manage this?

hi, http://www.zope.org/Members/mjablonski/howtoPDF I've updated my html2pdf-HowTo! I recommend "upgrading" to the new html2pdf.py-script for all people using the old one already... fixed problems with folders and a reasonable security-bug. greetings, maik -- Maik Jablonski Deutsche Zope User Group www.zfl.uni-bielefeld.de www.dzug.org

I had to manage some properties I called "Advanced", so I defined a suitable DTML File 'manage_advancedForm' (a copy-paste job from the standard Propertiers form plus some customization) -- see attachment. Then add something like the following: manage_advancedForm = DTMLFile('dtml/advancedForm', globals()) def manage_advanced(self, REQUEST=None): """Edit Advanced Settings""" adv = self.propertysheets.get('advanced') adv.manage_editProperties(REQUEST) if REQUEST is not None: return self.manage_advancedForm( REQUEST, manage_tabs_message='Advanced Settings updated.', ) Plus you have to tell Zope to draw a management tab "Advanced", so you'll add a dict {'label': 'Advanced', 'action': 'manage_advancedForm'} to your manage_options attribute. HTH, peter. ps.: I've taken this to zope(a)zope.org instead of zope-dev > Best Regards > > Lennart Regebro > Torped Strategi och Kommunikation AB > > > > >

ZMailIn patch
by Jean Jordaan 07 Jun '02

07 Jun '02

Hi there I've modified zopeMailIn.py to look for a client based on firstly the recipient fields, and secondly the 'cc' and 'bcc' fields (so that I can copy Zope on a mail I'm sending to a client, for example). I'm sending on the diff against ZMailIn-1_0_0 in case it's of interest .. -- Jean Jordaan Upfront Systems http://www.upfrontsystems.co.za

Can "Tutos" be set up w/ Apache on MS Windoze? Charlie Fulton <ccfulton(a)unity.ncsu.edu> on 06/06/2002 04:43:59 PM To: zope(a)zope.org cc: Subject: RE: [Zope] RE: Zope group calendar Tutos looks pretty neat... is a definite possibility. Now, since this thing needs PHP, how would one go about setting it up? Just a mind game here... Should I serve zope content with apache and also use it to serve tutos. Or is there a way to serve PHP scripts directly from Zope? One of the how-tos seems to have a way of passing the PHP requests through Zope to be rendered by apache. Is there any experience with an arrangement of this sort?

howto keep doc-types via WebDAV?
by Florian Konnertz 07 Jun '02

07 Jun '02

Hi zopies! I use davfs to edit my documents on the zope-server. I edit them on my local filesystem, then copy them to the remote server. All docs are after this ceremony from the type: text/x-unknown-content-type. How can I achieve to keep the type, e.g. dtml-docs ? I tried different suffixes (bla.dtml etc.) - No effect. I couldn't find anything in the davfs docu. Thank you in advance, Florian
