Re: [Zope-dev] Speed up the learning curve
I highly recommend the Quick Python Book if you're already a programmer, looking to learn the new language.

[Zope-dev] DTML sqltest tag and python expr. Bug in Zope Book?
Hello everyone, I was recently working on a quite big ZSQL method (around 100 lines). I was using only dtml-if and dtml-sqlvar tags and a lot of like '%...%', so thought I could make things look much nicer using dtml-sqlgroup and dtml-sqltest ... op=like optional. But I ran into a big hurdle: I quickly searched through the archive and found the thread [Zope-dev] ZSQL using LIKE operator, and in particular: http://lists.zope.org/pipermail/zope-dev/2001-February/009339.html which is exactly what I would like to do. But unfortunately, dtml-sqltest ... does not seem to work. We get the following error: The ... shorthand for expr was used in a tag that doesn't support expr attributes., for tag dtml-sqltest [...] I checked sqltest.py (Zope 2.3.2): no support for python expr in there. Interestingly, the Zope Book mentions the use of python expressions with sqltest in its DTML Reference: http://www.zope.org/Members/michel/ZB/AppendixA.dtml Is there a patched sqltest.py that I don't know about or is this a bug in the book? Anyway, does anyone know of a good reason why the sqlvar tag supports python expr while sqltest does not? Some obscure security hole? Or is the functionality just missing? And in that case, is anyone up for a patch? It's not critical, but the following kind of defeats the purpose of sqlgroup: dtml-sqlgroup where required dtml-if title title like dtml-sqlvar '%%%s%%' % title type=string /dtml-if dtml-and dtml-if author title like dtml-sqlvar '%%%s%%' % author type=string /dtml-if /dtml-sqlgroup The following would be much nicer: dtml-sqlgroup where required dtml-sqltest '%%%s%%' % title op=like type=string optional dtml-and dtml-sqltest '%%%s%%' % author op=like type=string optional /dtml-sqlgroup Note: in this particular case, I could preprocess the variables and add the surrounding wildcards in the call to the ZSQL method. But that would restrict the way this method can be called (URL traversal is definitively a cool feature to impress newbies ;) ), and that's not the point here anyway: we would just like python expressions in sqltest tags.

Re: Something better than ZClasses (was: Re: [Zope-dev] Re: Zcatalog bloat problem (berkeleydb is a solution?))
Python Products.
Ok.
3. Okay, here we should have a loop of enter images with upload
functionality. The only problem is where do we save them in the mean time?
Upload? Upload to where?
mk-zprod (as it works today) creates a directory on your filesystem, and
in that directory (which you just copy to your Products directory) it
creates an img/ directory and puts them there.
Well, but where are the images coming from. The Wizard is a Web Frontend,
so we would need to upload the images or copy them from somewhere else from
the file system.
BTW, the /img directory is non-standard. Better would be www/ since other
products use it as well.
In fact, we only need to think about adding them with the right permissions
to the directory. A piece of code in the __init__.py will do the rest:
# load all the icons automatically
from Globals import package_home, ImageFile
misc_ = {}
path = os.path.join(package_home(globals()), 'www/')
for file in os.listdir(path):
if file[-3:] == 'gif':
misc_[file[:-4]] = ImageFile('www/%s' %file, globals())
Or are you asking where the wizard should store them? (Which I thought it
didn't have to.)
Well, you can take two approaches here:
1. As soon as the user uploads the icon, we are adding it to the directory.
This is a problem, if you want to undo some or all of the wizard actions,
but is much easier to implement.
2. When the icon is uploaded, save it somewhere temporarily. At the end,
when all questioning is done, add everything at once. This has the
advantage that you can freely move back and forth until you finish the wizard.
5. Yep, how could that look like; should I provide users with a text area
or what?
In the dtml/ directory of mk-zprod you have Add2.dtml, that's the page the
user is redirected to after adding an object. Maybe a text area with a
suggestion (like Add2.dtml) in it?
Sounds good.
Hubbliski. We could provide them with standard classes as defaults
(Persistent, Explicit/Implicit, AccessControl) and suggest some
others. I'm not too sure about the ZClass thing.
Okay, for the first version that will probably suffice.
I usually add the 'default' key to each property dictionary and write
a two liner in the __init__ method to generate the properties with
their default...
Why not just have:
def __init__(self, attrib1, attrib2='something'):
doc string
self.attrib1 = attrib1
self.attrib2 = attrib2
Because this is horribly ugly and unflexible when you have 20 attributes. I
always have to change several places, if I modify, add or edit an
attribute/property.
which could come from such a description:
attribs:
name: attrib1 default value: None
name: attrib2 default value: something
Well, we can describe that right away in the standard property dictionary
form; then we do not need to parse or do anything else.
9. Again, that would be a loop. But my question here would be: Are you
using sub-classes that much. I have written one so far in all the
products ...
My latest projects sub-classes left, right and center. If we just have
the logic for a recursive loop there the user could add as many as s/he
wanted without it being much more work for us.
Okay, I just wanted to make sure it really has the additional usage, for
the extra effort.
Well, I was, but I'm moving to France the 8. of July and I've just come
home (to Norway) from England. England, Norway, France, Germany, France
all in just three weeks is a bit much :) (Oh, and I have to get an
apartment in Antibes.)
Okay. It would have been a good place to discuss this further.
Now, I looked at the mk-zprod code again. We need to make it a real Zope
Product with a nice management API, so that I can use the functions from
the Wizard.
For example we would need:
manage_make_initializeProduct(...)
manage_make_addClass(...)
manage_make_addProperty(...)
manage_make_addIcon(...)
manage_make_addSubClass(mainClass, ...)
If we define this API clearly, then we can use it later to automatically
generate ZClasses as well. Once the work, twice the reward! ;-)

Stephan

Re: [Zope-dev] Re: [Zope-dev]SmartSections 0.1.0 released
Hi Stephan, thanks for this. Sounds pretty useful. Thanks. Well, I should have waited with releasing it, but I thought it would be good, since SmartWizard can be using it. I promise that the quality and documentation will drastically increase with the next releases. IMPORTANT: SmartSections requires OrderedFolder! and CoreSessionTracking.. and Formulator.. and SmartWizard.. (or not?) It requires CoreSessionManagement? I could not find the spot in the code. Oh yes, it requires Formulator!!! Of course the heart of all the forms. ;-) Nope, SmartSections does not require SmartWizard. The Wizard just uses SmartSections. It seems to be happy with dependencies now but when I create a Smart Section in the ZMI I get snip error Yes, yes, yes. I was just too tired last night to think of everything! Okay, here the explanation and the simple fix (or necessary install step): SmartSectionElements use Forms to be added and edited. Since I did not want to hard code these forms and have them editable in the ZMI, you have to define a Form container. This Form Container can be any Folder. You simply need to add the boolean property 'isFormContainer' and all the section forms will be placed there. In addition to the first case: If you have your Form Container and it contains a Transparent Folder called 'Forms', then the forms are put in this Forms Folder for better organization. If you have further questions, feel free to contact me!

Re: Something better than ZClasses (was: Re: [Zope-dev] Re: Zcatalog bloat problem (berkeleydb is a solution?))
I just realised something. How do you need this to work? With regards to the wizard. Should mk-zprod produce the files and add them to a folder in itself? Or should it return everything for the wizard to handle? All what the wizard will do is provide the user with a nice interface/GUI to enter the information. I will then pass the information to the above mentioned management methods and the MakeZProduct Product will then generate the code and save it to the file system. BTW, we will assume that the user that runs the Zope engine has write access to /ZOPE/lib/python/Products.

[Zope-dev] RestrictedDTML w/isPrincipiaFolderish: error with CMF 1.1 and Zope 2.4.0
Hello.
I'm getting the following error message (see below) while accessing the
contents of a folder (http://localhost/cmf/Portal/FolderD/folder_contents)
underneath a CMF site instance.
I was testing Python 2.1, and CMF 1.1/Zope 2.4.0 (latest cvs checked
out versions). I do not have any problem while using CMF 1.1 (latest
cvs version), Zope 2.3.3, and Python 1.52.
The starting ZODB database is identical in both cases. However, I'm
not using the ZDebug product with Zope 2.4.0.
I'm just not sure if the issue is due to:
- CMF - isPrincipiaFolderish being used in the folder_contents skin
or
- Zope 2.4.0 - RestrictedDTML bug ?
or
- Zope 2.3.3 security mechanism bug ?
or
- bug in my acl setup
I feel the following priviledges should be sufficient ...
Access contents information
List folder contents
View
to access isPrincipiaFolderish.
Any pointers ???
