[Zope-dev] Homegrown vs. Storebought
I'd like to add two capabilities to my city government web site: 1. users should be able to initiate discussions about legislation pending before our City Council. i.e., discussions will be tied to the relevant bill document. 2. users must register in order to post. I'd like enough information so that if someone posts death threats or the like they can be tracked down. I don't need threaded discussions (though that would be nice) so I'm tempted just to roll my own. Is there anything out there in the way of easy to use discussion Products that I could pop in to my site without buying into a gigantic set of associated machinery a la CMF? As far as enforcing some minimal accountability on the part of posters, the Membership product seems like my best bet, though there are some things I'd like to change, e.g., I'd like user info stored in a SQL db, not Zope, passwords should not be encrypted 'cause I want to send them out every month, and I want different info. stored about users than the default properties provided by the Product. How hard do you think this would be with Membership? Are there any other Products I should consider IYO?

Re: [Zope-dev] Page Templates: Any plan how to use PT's for I18n and browser dependant templates etc?
How would this effect the page cooking and template cache? Cooking isn't affected. You would naturally want to make your cache sensitive to the same REQUEST parameters as the switching script. Hm. ok. PS. Page Templates are great but I have yet to figure out how to use them with the "Content is folderish" pattern. You can acquire a template into a content folder, then use "here/" paths to access bits of content. Is that the sort of thing you mean? You mean like having a "global" index_html template and tal:content="here/my_content" to get the content? That would probably work. Now comes the tricky thing, case I want to render with the tal tags intact. I just tested that and they are intact after render. Jippi! The next step I want to do is to save the template back to Zope and extract some of the tal:content tags and save them back to my_content. I noticed that I can access the macros of a METAL template after its been cooked (or used anyway). Is there anyway to parse a TAL template to extract part form it, preferably from Python? TIA/Johan PS.

From: "Johan Carlsson" [EMAIL PROTECTED] Now comes the tricky thing, case I want to render with the tal tags intact. I just tested that and they are intact after render. Jippi! This will be optional in ZPT 1.1, most likely. The next step I want to do is to save the template back to Zope and extract some of the tal:content tags and save them back to my_content. Wha? You want to parse out the rendered contents of some tags and save them? Will the user be editing the rendered page somehow?

[Zope-dev] Form error handling for Rack-stored PD classes in O-O application
Hi,
I often have more luck the second time I ask a question... let's see
if this rule holds.
I'm struggling with checking and reporting errors in forms that
create or modify properties of PD classes in a ZPatterns application.
Automatic checks using Zope's built-in constraints or something like
ValueHandler won't cut it, because they can't cover all the required
rules - for example, checking if a Product SKU is being set to an
existing SKU, or that a Customer is trying to use an email address
already in use (and also because I want to return the form page with
the errors indicated, rather than a generic error page). So I need a
specific verification method for each class. This method will be used
both when an object is edited and when its created. To use the method
when creating an object, I either have to place it in the Specialist
- which is bad, because the PD class should provide its validation
code, or call it at commit time, using a SkinScript WHEN OBJECT
CREATED,CHANGED clause. But verification methods called at commit
time do their checks on the object properties, not on any submitted
form field values. So they can test that a password is reasonably
secure, but can't check that passwords typed in two form fields are
identical.
One thing I can do is define a editInstance method which would verify
the values in REQUEST.form and then call manage_changeProperties, or
store a list of errors in the REQUEST and raise a 'FormError'
exception. But I can't let this exception propagate freely, I have to
catch it so I can display an appropriate error page. Also, if a form
results in the creation of more than one object, I want to display
all the errors that result from the creation of all the objects, but
if the first object raises an exception, I can't create the second
one (especially if the second one expects to get the id of the first).
Or I could forget about exceptions and simply return an error list
from editInstance. Then it would be up to the method calling
editInstance to raise an exception to roll back the created objects.
This is the only workable solution I got at the moment... I can get
it to work, but I've chased solutions in the past that seemed good
but ended up crashing... so I'd really appreciate any comments on
possible flaws or problems I'm not seeing, or any other, better
solutions.
This is what it would look like (just an example, not showing cases
where more complex stuff happens, like 2 objects being created with a
single form):
In Customer (DataSkin PD class):
def editInstance(self, REQUEST, errors):
err = self.verify(REQUEST)
if err != {}:
errors.update(err)
else:
self.manage_changeProperties(REQUEST)
def editInstance_html(self, REQUEST, RESPONSE):
"""Action method for editInstanceForm_html"""
errors = {}
self.editInstance(REQUEST, errors)
if errors != {}:
html = self.editInstanceForm_html(self, REQUEST, errors=errors)
raise 'FormError', html
RESPONSE.redirect('editInstanceForm_html?message=Changes%20saved.')
def verify(self, REQUEST):
errors = {}
if REQUEST['name'] == '':
errors['name'] = 'Please provide a name'
return errors
In CustomerManager (Specialist):
addCustomer(self, REQUEST, errors):
ni = self.defaultRack.newItem()
ni.editInstance(REQUEST, errors)
return ni
addCustomer_html(self, REQUEST, RESPONSE):
"""Action method for addCustomerForm_html"""
errors = {}
ni = self.addCustomer(REQUEST, errors)
if errors != {}:
html = self.addCustomerForm_html(self, REQUEST, errors=errors)
raise 'FormError', html
RESPONSE.redirect('manageInstances_html?message=New%20customer%20created.')
And, of course, I can also have WHEN OBJECT ADDED,CHANGED CALL
self.ensure_valid(), to catch anything that might get by the above
checks. ensure_valid will raise its own error page, independent of
the above.
TIA for any help/comments
