Re: [Zope] ZEO manageUndo not working - DisconnectedError
Hi Sebastian, Am 06.05.2015 um 15:26 schrieb Sebastian Tänzer: After further testing I was able to sort this one out by downgrading ZopeUndo to 2.12.0 (pip install ZopeUndo==2.12.0 --force —upgrade). PyPi only said 4.0 brought Py3 compability. Should I expect any problems using ZopeUndo 2.12 + ZEO/ZODB4/ZODB3 with their latest versions? Undo has long been a standard functionality in Zope2 but proven to be quite dangerous as it is possible to totally mess up your object tree. IIRC undo has therefore been removed even from the ZODB - that is what you are experiencing with the current version. What seems to work quite well is to enable history support where you have access to every old transaction and can compare or copy them to be on top of the stack - which avoids the problem with disappearing transactions as Undo has. Unfortunately out of the box only a few Products have history support enabled. Some monkey patching can enable it for many of the other Products of stock Zope2. ObjectManager/Folder is a bit limited since accessing a whole historic version of a subtree can't be done easily. However, if you are interested and want to try: http://old.zope.org/Members/tino/PatchHistory/view (very old, but seems to work with the 2.12 at least) Best, Tino Best, Sebastian ___ Zope maillist - Zope@zope.org https://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - https://mail.zope.org/mailman/listinfo/zope-announce https://mail.zope.org/mailman/listinfo/zope-dev )

Re: [Zope] delete a variable from REQUEST

Hi,
thanks for ur reply.
My problem is, my code is like
#code code code
if REQUEST['usr_msg']:
do some operations.
#some code related to project
my program control loops with above if condition.
REQUEST is in same context.
so once REQUEST stores 'usr_msg ' every time when it goes to if
condition , it performs that do some operations
Due to above reason i want to delete that usr_msg variable from REQUEST
But if you would really manage to delete this from REQUEST, you
would get an exception when trying to use it in the way above.
So, see Peters solution to your problem.
also i cannot put restriction on usr_msg ,because it comes from user
input, and user can give any text to that variable.
If thats some kind of filter chain you probably want to change
it to some private name space within request as you would be
comfortably getting by REQUEST.set('allmystuff',dict())
at the very beginning. You can actually look up form values
from REQUEST.form to distinguish between user input and
data from your program. If you just ask REQUEST, you get
some kind of stacking layers of name spaces where values get
looked up.
Please see the Zope book (online) for description of the API.

You should check the tales documentation. the pipe symbol |

the right part of it is evaluated.
In the special case it probably is nicer to use:

defaultnosta/div instead so the fallback value is part

I would also recommend not mixing and ' for attributes and

If the file is posted as attachment (similar to file upload) it should

For this to work the data needs to be sent as

...
The only trick here is to get the javascript to include the dynamic

I usually use for that::
!-- assumes that 'image' is bound to an actual Zope image object --
script type=text/javascript lang=JavaScript
tal:define=img_url image/absolute_url
tal:content=string:var img_url='${img_url}';/script
Your popup javascript can then refer to the 'img_url' JS variable to set
the window location.
A little bit cleaner approach would be to have an ordinary link:
a class=magnify href=path/to/big/imageimg src=path/to/thumbnail
width, height ... //a
and have a general javascript which scans thru the DOM after load,
finds the a-objects with class-attribute magnify and installs
an handler for mouse click which overrides the usual link action
and either pops up a window or uses layers the big view on top
with little DOM action (preferred). You dont even net buzzy Ajax
for this. The URL for the big picture is just encoded in the HTML
already, so you can use the usual tal: attributes to define in

Well, it looks a bit silly - I mean you make
a hand-written ORM? This would be the time to
either write a real ORM as product or try
some of the available: ZPatterns, Archetypes, ...
Usual database interacting zope solutions
have only a handful insert places where you
need bulk inserts. And even then you can just
call one ZSQL method (per table) in a loop
to insert your values from a list.
More, sql_quote does not really work
for tablenames or column names - it
may work by accident for MySQL though,
but not for standards compliant databases.
There's the whole sqlgroup thing.
Well to be honest I never used it ;)
dtml is after all depreciated, so I can see no reason to learn it as torougly
as ZSQLMethods obviously requires when I can use python instead.
You always can but what do you gain? How does your python script
code look like for the above problem?
And a sea of too specific templates is even worse.
Well from some level of complexity you could also use
database functions. But if its so complex, why using
MySQL?
Don't see quite what you mean here, but it would be just the same problems
with PGsql.
Not direct related but if you have complex queries,
e.g. join over many tables, partial indexes, subqueries, ...
it may be a bit hard to get reliable performance with MySQL.

No, the content of your variable sql is wrong :-)
dtml-var sql would indeed work if it contains valid sql
code.
It did not.
That was the whole point of this mail.
The method was dtml-var sql and the sql was select * from foo
care to spot the invalid code in that?
wait... your variable really is named sql? Maybe that is
the problem. I did not verify this but it could be. DTML
is sometimes weird ;)

Hm.. interesting, but I looked into it a bit, and I can't find where this
happens.
I see that ZRDB/DA.py does: argdata['sql_delimiter']='\0'
Tried a query = query.replace(';','\0') at line 444, but to no effect :)
Interesting. I must admit the whole ZSQL Code is very old and ugly
and I even removed some parts in my private installations ;)
Suggestions?
I guess this could be a problem with LAST_INSERT_ID, forcing me to use
ZSQLMethods, or dome ugly workaround for inserts, where I need the id
afterwards.
Last_insert_id is really part of the uglyness of mysql. But you would
work around with distinct ZSQL Methods. See these methods as interface
and really methods of your database to interact with your data model.
Transactions are maintained thrughout your session (read: request)
so there is no need to squeeze it all into one ZSQL call. Every
subsequent ZSQL call inside your request will be in the same
database transaction

dtml-call? wtf! This will never ever work since dtml-call does not

You above example would also not work since _['page']
would read a variable named page from _ namespace,
which would try to look up properties first and
only as last resort look for request variables.
There is REQUEST even in DTML.
Also note, design has long since moved away from frames
(Yes I know ZMI still uses them) - it makes things with
application servers much more easy if you don't use frames.
Easiest way is to return rendered pages from python script
for example
pagename=context.getProperty('page','defaultpage')
return context[pagename]()
as a python script would do the trick.

You could use a catalog if you have other searching requirements, but the method objectIds() (see the zopebook for more info) will return a list of contained Ids, which you can then sort to get you what you need. Also, len(somefolder.objectIds()) will give you the next available id (assuming your object ids have some sequential numbering). Which both would not exacly emulate a sequence.

Can you elaborate on that? I dont see a reason why you would

database conflicts)
I understand that there is a way to handle transaction controll in the
ZMySQL
methods. However I find no documentation at all on how to use it.
Well most databases accept COMMIT as sql command.
Without using ZMySQL methods I would be using the following piece of code:
db = mysql.connect(host=localhost ...)
cursor = db.cursor()
query = CALL insertUser('%s', '$xxx$', @id, @error);select @id, @error
% 'JohnTheUser'
cursor.execute(query)
# get the next resultset, it has the result of the select
cursor.nextset()
result = cursor.fetchall()[0]
error = int(result[1])
if error:
print error %s when trying to add user %s % (ERRRORS[error],
'JohnTheUser')
db.rollback()
continue #we are in a loop actually
what does the loop?
..
db.commit()
How can I mimic that using ZSQL Methods
Are you adding users in a series? What exactly
are you doing? If its kind of migation, consider
running it as a script with zopectl run migationscript.py
once. There you could just write python code as you like

Yes but what if tomorrow you create a product? need work to times: you first, me later Who says you have a use for the product I create? Or if it makes sense to catalog it? If you want a cataloguing framework, why dont you use CMF or something? I want to make every class catalogable only if I point a zcatalog id (with self.default_catalog) but If I point it I want to catalogue the object And what of the object do you want to catalog? Which kind of indexes do you want it to support? What kind of questions do you expect your ZCatalog (hypothetically) answered? Could you give examples? Is not important what I want to catalog, for me is important that the object *was* in the catalog (some catalogs indexes some properties some others other properties) Please read the catalog section again: there isnt the object in the catalog! Again: The object is _not_ in the catalog. Its all about usefull indexes and maybe object metadata. So again: _what_ actually do you expect to find? Now is a search era, isn't it? Yes, search for what and by whom is the question here. I don't thing so. The question is who is in the catalog Use another framework only to do the objects catalogable? I love simple things So why are you trying to make standard zope objects more complicated? :) More complicated? Sure, but I don't understand the cost to make every object in Zope catalogable. A class and a variable I don't thing is a big cost And I thing in Zope when I thing in keep it simple Yes, but its nonsense. You cant do anything more with the objects in Zope if they are catalogued. In my opinion (is only an opinion) these is not the best situation in a future Sorry but is not so acceptable for me The point is, it makes no sense to catalog Pagetemplates, Python Scripts, Folders and ZSQL Methods, Mailhosts and Database connections. These are all standard zope objects, yet they make catalogable content only in derived work or when they play together - which is a custom solution anyway. There you can add whatever cataloguing awareness you want. And if I use them dinamically (a user with the role1 use the template Ver but a user with the role2 use the template Ver1 for the same context)? (I'm not sure if I understand you clear, sorry If I make a mistake, please This would not be supported by just adding indexing to the standard objects anyway. You would write a container which supports the bahavior you want - and while you are at it you can easily add catalogawareness to that - exactly where and in the way _you_ need it :-) Individual objects cataloguing themself would get in your way. Regards Tino Wildenhain Yes, I'm creating a specific container that works in a curious way. In that container I could catalog a Page Template when I'm adding it but perhaps sometimes I want to track its changes an so on Yes, but who should know what _you_ want your objects to do? You cannot expect all people (especially the ones writing zope core) to guess your needs - you are the one to express your wishes in the form of code :-) If you end up having a general solution (like these frameworks are) you can share them with others.

Again: The object is _not_ in the catalog. Its all about usefull indexes and maybe object metadata. So again: _what_ actually do you expect to find? When I talk about was in the catalog I mean the object is catalogued I expect to find *the object* in the catalog For example: How do you know how many cousins you have? Because you are a catalog that catalog the number of cousins you have So you want to count objects based on their meta_type? Of what use would be such an information? What if you know how many pagetemplates you have? :-) Another example: how much skills about computing do you have? Again your skills are objects that you need (as a catalog you are) to catalog We have a skills object in plain zope now? Thats news for me. Like an entity (a thing, and object) you need to know some data stored in your life added to you Yes, but a zcatalog cannot work with some data - you need to specify exactly _which_ data you want to find. So what exacly is this on standard Zope objects? .. Yes, but its nonsense. You cant do anything more with the objects in Zope if they are catalogued. Are you sure? I can find them!!! Then if I can find them I can count them, give to you (even if its don't depend on me, remember your skills or your cousins?) Ah yes, which zope product stores cousin data? I want to create an object that acts like an entity (like a human or a mortage or a paper or a product -that you can sell) Yes, you crate it - you define its cataloguing. So what is your business with standard zope objects here? These entity need to know how is it (its properties, its characteristics) You cant barely catalog all properties - the catalog would not even know if this property is meant as keyword or fulltext or whatever... I ask myself if I know myself but I only know about myself all I can catalogue ... Regards Tino I don't expect anyone guess my needs (is for that I need to develop the class) :) I only ask if I can add some super classes to an object when I create it :) You can, you just add it. Its there and you even know its name. So what was your problem again? :-) I know my needs are so particular but I want to create something new with a new perspective. If I can the result will be very curious (I suppose, I expect even) I choose Zope because is the most near to my finall result Exactly :-) Regards TIno ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )

Garito wrote: Yes, the indexes depends on the entity (I don't know what indexes I use until I define the entity but I need to catalog every characteristic of the entity) For example if I have a entity with a container where to put my cousins information I will catalog a keyword index called (is an example, remeber) HowMuch that counts the number of the objects stored in the container Or if I talk about skills I will catalogue the marks or the way to print the certificate of excelence (again an example) But then you can create specific subclasses that are catalog aware. What standard objects would you use to implement this? You have a specific, non-generic use-case that has already been catered for by the framework. I can't subclass every class I need. These will need to reajust (subclass) every new case For example: Now I know I need Page Templates and Script Python catalogaware, then I subclass them and I finish the work, good But tomorrow I need a Mail host catalogaware, begin again and create a subclass for Mail host haha. I wonder which property of that single MailHost object you probably use you want to catalog and what exactly would be your Query to the ZCatalog, once you want to find out... I would like if there are a generic way to add catalogawareness by code. If there are my problem about catalogawareness finish Speaking of code: did you think about my hint? I mean the one with the loop - if you have the weird notion you need to make anything catalogaware, why dont you write a product which iterates over all other products in zope, and if not catalogaware, generate a generic catalogaware subclass for you? Heaven, you could even half way finished by the tiem you feed the thread :-) Regards Tino ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )
