Re: [Zope] zeo clients not synchronized, modifications not shown
Hi Christopher, Great pointers, thank you very much for your response! I use pound for load balancing (from the beginning - nothing changed here). I will investigate using your indications.

Re: [Zope] charset problems (utf-8)
Hi,
You have to make sure that everything has the same encoding (strings, text
values). I recomend you to convert everything to unicode and then put
something like below as a first line in your page:
span
tal:replace=python:request.RESPONSE.setHeader('content-type','text/html;charset=utf-8')
/
and in the HEAD
meta http-equiv=Content-Type content=text/html; charset=utf-8 /
HTH,
Dragos

Yellow,
I've noticed charset problems displaying HTML pages.
Let's say I want to display a page using a DTML Method like this:
html
head
...
/head
body
á Á à À ç
/body
/html
This page is ok and I can see the portuguese letters fine.
The problem starts when I do this:
html
head
...
/head
body
á Á à À ç br
dtml-var sometextfield
/body
/html
The first line of characters shows some strange characters and the
sometextfield shows up fine even if it has the same portuguese
characters.
sometextfield comes from a mySQL server using utf-8 as charset and
collation.
zope.conf has the following:
rest-input-encoding utf-8
rest-output-encoding utf-8
The browsers also have UTF-8 as the encoding (safari, firefox and
chrome) all show me the same problem.
I also noticed some strange behavior...
If I create á Á à À ç as a property field using ustring and call it
as dtml-var someproperty also gets fine in the browser.
Anyone seen this??? Double encoding maybe???
TIA

[Zope-dev] Strange Cut/Paste or Copy/Paste or Import/Export behavior
Hi all,
I have to containers old_container and new_container that accept objects of
the same type. The two containers are actually instances of different
classes in the same product.
I want to move all the objects from old_container to new_container. I have
tried with only one object:
1. To move it with a simple Cut/Paste operation through ZMI: the object is
moved successfully, but has missing properties
2. I have used Import/Export to move the same object: the object is imported
successfully, but also has missing properties
3. Even tried a simple Copy/Paste: same result, no errors but missing
properties
Basically, the code for the object to be moved is like this:
class Country(Discussion, Folder):
_properties = (
Discussion._properties
+
(
{'id': 'body', 'type': 'text', 'mode': 'w'},
)
)
def __init__(self, id, title, body, comments, flg_notify):
self.id = id
self.title = title
self.body = body
Discussion.__dict__['__init__'](self, comments, flg_notify)
def check_properties(self):
print hasattr(self, 'body')
print hasattr(self, 'comments')
and
class Discussion:
_properties = (
(
{'id': 'comments', 'type': 'int', 'mode': 'w'},
{'id': 'flg_notify', 'type': 'int', 'mode': 'w'},
)
)
def __init__(self, comments, flg_notify):
self.comments = comments
self.flg_notify = flg_notify
If i run the method check_properties before move/copy/import it prints
True+True. After step 1/2/3 the result is True+False. So the missing
property is 'comments', that comes from the extended class Discussion. If a
I trie to acces the Propeties tab, manage_propertiesForm method, I get:

Re: [Zope] Get raw data (byte array) from flash in Zope
Hi,
The solution is very simple :)
Instead of sending the byte array like in the example, just encode it
as a string and send it in a variable using POST:
- base64 - this doesn;t works all the time... i don't know why
- bin to hex - works all the time
The server side code is like this:
img = REQUEST.form.get('picture', None)
if img is not None and img != '':
img = binascii.unhexlify(img)
img = PIL.Image.open(StringIO(img))
img.save(join(..., 'picture.jpg'))
We made tests with a lot of images, even with images of 10MB size. It works...

[Zope] Get raw data (byte array) from flash in Zope
Hello everyone, I have a question about how to get raw data sent by a flash application in Zope (a zope method/function). The flash application uses the method in the link below to send to the server an image (jpg): http://www.zedia.net/2008/sending-bytearray-and-variables-to-server-side-script-at-the-same-time/ Searching through the internet I have found a PHP example that gets this byte array sent from flash: http://blog.joa-ebert.com/2006/05/01/save-bytearray-to-file-with-php/ They are getting the date form a header called HTTP_RAW_POST_DATA. The question is: how can I get this data on the server side in Zope? Becasue: - REQUEST.form is empty - HTTP_RAW_POST_DATA is missing - there is no other key or value in the REQUEST to indicate the value I am looking for On my local devel machine I managed to find a solution: - using Zope 2.10.3 I have enabled use-wsgi (on) (without apache) - in zope, the method called from flash is something like this: ... v = REQUEST.environ['wsgi.input'] v.seek(0) f = open(join(SOME_PATH, 'image.jpg'), 'wb') f.write(v.read()) f.close() return '1' This solution doesn't work on the production environment - Zope 2.11.4 with ZEO (pound and apache in the front of zope as load balancer and web server).

[Zope] strange database read conflict error
Hello everyone, I have a question regarding a database read conflict error. I would appreciate any thoughts on this issue.

[Zope] ExtFile 1.5.6 bug
Hi, I am experiencing a very strange problem; any thoughts or ideas will be highly appreciated. I am using ExtFile 1.5.6 product to store images and files in my application. During the publishing process, at some point, a rename of a container with images and files it is involved. From time to time this results in broken objects with 0 byes in size. My application runs on a Zope 2.7.6. On the other hand, I am running the same kind of publishing process on a Zope 2.10.4 with ExtFile 2.0 and this problem never occours. I noticed a line in the CHANGES.TXT file: - Bugfix: Exceptions at a late stage of a cut/paste operation could lead to data loss. Can this be the bug that affects my application when I use the ExtFile 1.5.6 product? Because a migration to a higher Zope version is out of the question right now, is there a fix for this problem? Or is there another way to overcome this?

[Zope] metal:fill-slot and tal:condition
Hi everybody, I am stuck with the following problem. I would appreciate it very much if you could help me with it. So I have a ZPT where a macro is defined with several slots; one of the slots like below: tal:block metal:define-slot=slot_issue SLOT DEFAULT CONTENT /tal:block The common way to put other content in the slot is: tal:block metal:fill-slot=slot_issue CUSTOM SLOT CONTENT /tal:block Now, in a ZPT that uses the above marco I want to replace the default slot content with other stuff *only* if a condition is fulfilled: tal:block tal:condition=condition-code metal:fill-slot=slot_issue CUSTOM SLOT CONTENT /tal:block If the condition-code returns True then the CUSTOM SLOT CONTENT is put instead of the default slot content - correct. If the condition-code returns False then nothing will be displayed - this is not correct?!. I also tried somthing like: tal:block tal:condition=condition-code tal:block metal:fill-slot=slot_issue CUSTOM SLOT CONTENT /tal:block /tal:block In this case the content of the slot is CUSTOM SLOT CONTENT in both cases - the result is True or False. The only solution that I can think of is not elegant at all because I have to duplicate the slot_issue's default content: tal:block metal:fill-slot=slot_issue tal:block tal:condition=condition-code CUSTOM SLOT CONTENT /tal:block tal:block tal:condition=python:not condition-code SLOT DEFAULT CONTENT /tal:block /tal:block Is there other wat to accomplish this?

[Zope] changing the meta_type for python product class
Hi everybody,
I am stuck with the following problem for witch I don't have a
solution. I would appreciate it very much if you could help me with
it.
I have a very simple Python product with only one class that extends
Folder. The name of the product is MyClass and the MyClass.py module
is below:
from OFS.Folder import Folder
from Products.PageTemplates.PageTemplateFile import PageTemplateFile
from constants import *
manage_addMyClass_html = PageTemplateFile('zpt/myclass_manage_add', globals())
def manage_addMyClass(self, id, title='', REQUEST=None):
ob = MyClass(id, title)
self._setObject(id, ob)
if REQUEST:
return self.manage_main(self, REQUEST, update_menu=1)
class MyClass(Folder):
meta_type = METATYPE_MYCLASS
def __init__(self, id, title):
#constructor
self.id = id
self.title = title
And the constants.py module contains:
import Globals
MYCLASS_PRODUCT_NAME = 'MyClass'
MYCLASS_PRODUCT_PATH = Globals.package_home(globals())
METATYPE_MYCLASS = 'My Class'
PERMISSION_ADD_MYCLASS = 'MyClass - Add Components'
In the ROOT folder I create the following python script (listing):
for x in container.objectValues(['My Class']):
print '[%s] - [%s]' % (x.meta_type, x.absolute_url())
return printed
Then I follow the steps:
1. Create an instance with the id 'instance1' (in the drop down I have
'My Class').
2. I run the 'listing' script and I get:
[My Class] - [http://10.0.0.37:8080/instance1]
3. I change the constant METATYPE_MYCLASS into 'My New Class'
4. I run the 'listing' script and I get:
[My New Class] - [http://10.0.0.37:8080/instance1]
5. I create a second instance with the id 'instance2' (in the drop
down I have 'My New Class').
6. I run the 'listing' script and I get:
[My New Class] - [http://10.0.0.37:8080/instance1]
7. I modify the python script by changing the 'My Class' with 'My New Class'
8. I run the 'listing' script and I get:
[My New Class] - [http://10.0.0.37:8080/instance2]
In the ZMI for both instances the meta_type 'My New Class' is
displayed. I don't understand why the first instance is not displayed
after I change the meta_type value in the python Product.
Moreover, if I try to explicit update the meta_type property for the
first instance to the new value, the result is the same.
What I am trying to accomplish is to be able to change the meta_type
value and this to work (e.g. with no effect on python scripts like
'listing')
Thank you very much,
Dragos

Re: [Zope] Adding HTML to Python
if you are using ZPT to display the result of the method use 'structure', if you are usign DTML make sure you dont't encode the result if is plain text use new line character as I sad above. regards, Dragos On 12/6/06, April Lekin [EMAIL PROTECTED] wrote: Hi, I tried that and it will print the BR, like this These IDs have Errors:BR 1BR 46 BR 76BR 45BR At 09:43 AM 12/6/2006, Roberto Benitez wrote: add BR to the end of each line example: l_errorMessage = These IDs have ErrorsBR #ADD BR AT END OF HEADER LINE Loop l_errorMessage = l_errorMessage + %sBR % (ID) #ADD BR AT END OF EACH ID ENTRY end loop - Original Message From: April Lekin [EMAIL PROTECTED] To: zope@zope.org Sent: Wednesday, December 6, 2006 11:12:20 AM Subject: [Zope] Adding HTML to Python In Python I'm building this error message: l_errorMessage = These IDs have Errors Loop l_errorMessage = l_errorMessage + %s % (ID) end loop return l_errorMessage.

Re: [Zope] changing the meta_type for python product class
Hi!
Thank you very much for your response.
Ok, you are right, but if I do it why the ZMI is showing to me the new
meta type for both instances? This is wrong...
Also, I don't understand why if I explicit change the meta_type
property for the old instance (e.g. a method of MyClass that is called
via URL) still nothing happens?
I also tried to add the following lines to the MyClass:
_properties = (
Folder._properties
+
(
{'id': 'meta_type', 'type': 'string', 'mode': 'w'},
)
)
In the Properties tab for both instances the same value is shown for
the meta_type property.
Thank you very much once again for taking time to consider my problem.
Regards,
Dragos.

What I am trying to accomplish is to be able to change the meta_type
value and this to work (e.g. with no effect on python scripts like
'listing')
The best way is *NOT* to change the meta type (at least not when
you have places that require it unchanged).
Instead derive a new class from it and give this new class a new
meta_type.

Re: [Zope] batching help
Hi
I suggest to use the following function that
def get_grouped_list(self, seq=[], size=3):
#get the list with all items grouped
return [seq[i:i+size] for i in range(0, len(seq), size)]
that takes as parameter a list and goups items in slices with length = size.
def get_grouped_list(seq=[], size=3):
... return [seq[i:i+size] for i in range(0, len(seq), size)]
...
l = [1,2,3,4,5,6,7,8]
get_grouped_list(l)
[[1, 2, 3], [4, 5, 6], [7, 8]]
get_grouped_list(l, 4)
[[1, 2, 3, 4], [5, 6, 7, 8]]
Then iterating this is something like:
tr tal:repeat=slice python:someobject.get_grouped_list(yourlist)
td tal:repeat=item slice
span tal:replace=item /
/td
/tr
Hope this will help.

Re: [Zope] Character set problems
Hi Here are some things you can do to handle your problem. For me, this approach worked just fine. 1. Your HTML pages must have set the encoding to utf-8. Put this in the HEAD tag of your html pages: meta http-equiv=Content-Type content=text/html; charset=utf-8 / 2. For the Root folder add a property named 'management_page_charset' of type 'string' with the value 'utf-8'. In this way the ZMI pages will be displayed with utf-8 encoding. 3. Modify your HTML code like this: input name=test:utf8:ustring / If 'test' is also a property of some object, make sure it has 'ustring' type. After that the value will be displayed correctly in all pages. Note: If your Zope runs over an Apache you must check also the Apache settings (to serve pages utf-8 encoded) Hope this will help.

[Zope] Multilingual content class with LocalPropertyManager
Hi
I want to build a multilingual content class with LocalPropertyManager
from the Localizer product. Also, my class extends the File class,
something like:
class MClass(LocalPropertyManager, File):
title = LocalProperty('title')
description = LocalProperty('description')
def __init__(self, id, title, description, file, precondition,
content_type, lang):
File.__dict__['__init__'](self, id, title, file, content_type,
precondition)
self._setLocalPropValue('title', lang, title)
self._setLocalPropValue('description', lang, description)
The problem is that everytime I call the title property it doesn't
return the LocalProperty 'title', but instead it returns the value
entered when the object was created.
From a ZPT, if lang is the current selected language and is 'en':
span tal:replace=here/title / - don't get the correct value for the
selected language
span tal:replace=python:here.getLocalProperty('title', lang) / -
correct value
Not event after editing the object properties, the 'title' value remains
the same: the value entered when the object was created.
I tried not to call the File constructor, but it doesn't work also. My
LocalProperty 'title' is somehow 'hidden'.
Could you please give me some indications about what am I doing wrong?
Is there another way to have a class like MClass?
Thanks a lot,
Dragos
