__setstate__ and acquistion
by Terry Hancock 28 Nov '03

28 Nov '03

Okay, I was trying to use acquisition from within a __setstate__ method. Doing a little searching I was able to find a message from the Zope list (circa 2001) saying that you can't do it, because the self that __setstate__ acts on isn't acquisiton wrapped. However this is really unfortunate, as I was hoping to acquire some information I need for updated the object from the Zope instance of the top-level site object. Is there a way to do it? Can I explicitly search somehow? Or can I mark the object as needing to be updated and catch it at some other point? (But where!? __bobo_traverse__ perhaps?). Any suggestions? Thanks, Terry -- Terry Hancock ( hancock at anansispaceworks.com ) Anansi Spaceworks http://www.anansispaceworks.com

Export with Zope-Roles
by Holger Schmidt 27 Nov '03

27 Nov '03

Hi, my situation: I have a Folder - Folder1 - which has all needed rights for users with roles role1 and all needed rights for users with role2. In Folder1 there exist two Folders: Folder2 and Folder3 that only have rights for role1 OR role2 (rights are not aquired from Folder1...) If I try to export Folder1 as a user with role1 OR role2 the export contains both folders, Folder2 and Folder3 (but I do not have access to both folders ...). --------------------------------------- Folder1 (Role1 AND Role2) | |-Folder2 (Role1, NOT Role2) | |-Folder3 (Role2, NOT Role1) ---------------------------------------- Does that mean that if I have the "export"-right in a special folder I am allowed to export all inner folders with that folder? Or did I do something wrong? Is there a possibility to export just those Objects in a Folder for which I have the "export"-right, or will I have to write something on my own ...? -- Thanks, Holger

You should estimate the size of each object and add them up. Remember that a new version of the object is stored each time it is modified and commited (packing the database removes old versions).

No, you can have many more simultaneous users. Don't worry about this.

Did your Data.fs file really grew up to 2GB? Being currently at 10MB? Maybe it's another file related to your application. Or you need to pack more often...

RE: [Zope] Could I build this application with zope?
by John Hobson 27 Nov '03

27 Nov '03

Thanks to those who have given it a quick glance, I appreciate it. I absolutely want to use as much as I can off the shelf, the less coding and modification I have to do the better! I was looking at the plone user manual and a lot of the features in there didn't seem to be that relevant, but certainly some of the features in CMF could be built upon. The really important bit of the application is the workflow bit - getting a course from business case stage to release, to being withdrawn. If my understanding is correct Dcworkflow is an object based workflow solution, whereas I am looking for a process based solution. I found openflow which is processed based, this seems to fit our requirements better. The course (online) will never be directly part of this system, just all of the meta information about it. At points in the process we know more information about the course (duration, description, name, planned live date and documents such as business case, invitation to tender etc) and this information would get inputted to a RDBMS (probably mySQL). So basically each stage of the process will have a number of form fields that need to be filled in , or documents uploaded by a number of users to advance to the next stage of the process. The thing that worries me about openflow is how easy it would be to change the process. I've not heard of Archetypes, I will take a look and see what that does. We are also looking at proprietary business process management/change management tools (e-work and infra) as an alternative to an oss solution.

I didn't do any detailed analysis, but on first glance, yes. Not only that, more of this solution may be available off-the-shelf than you realize. Take a long, careful look at Plone and Archetypes before you go messing with CMF yourself. I'd bet Plone already does 90% of what you want and Archetypes can pick up most of the rest. HTH, Dylan

Could I build this application with zope?
by John Hobson 27 Nov '03

27 Nov '03

Thanks to those who gave useful replies to my earlier post. I am still looking into using zope for my project. It looks like the CMF could provide a number of the features that I am looking for and that a number of others would have to be custom developed. Is it a realitively straight-forward process to develop custom functionality? Follows is a brief synopsis of the functionality that I am looking for, for this project, I would appreciate if anyone could take a quick look and let me know if zope may be suitable. Thanks, John We require a software solution to: 1. control and manage the course development process and to enable communication between all internal teams and individuals concerned with the product 2. act as a central data repository and management tool for all key product information both pre and post product release. What functions are required of the system? The process * The system will prompt users to input information at key stages in the process. At each stage different groups of users will be required to enter data and/or upload documents. * The system will identify accountable and responsible persons for each stage in the process. * A limited (less than 6) set of stages will need to be user-defined for each product passing through the process, the system will need to suggest default stages common to most projects. In addition to these stages there are 7 mandatory stages that all products must pass through. * The data that is inputted to the system will need to be visible and available to user groups based on their permissions. * As part of the development process there is a requirement for external developers to input data into the system which will need to be verified by a Ufi employee. * A course can be one of four different types, each will have a differing development process. Course Tracking Reports * Users must be able to produce their own reports based on sets of courses and the stages that the courses are at in the development process. * Previously run tracking reports can be saved for future use without having to enter the criteria again. * Tracking reports can be downloaded in a format that can be read by MS Excel. Alerting * Users will be able to subscribe themselves to email alerts which are triggered by certain system events that will include: o Certain courses moving on a stage in the process o Changes of data relating to products Qualitfications * The system will be able to capture the relationship between qualifications and learndirect products * Qualifications and their associated assessments and units will be inputted into the system will need to be associated to products at the unit level Searching * Users will be able to perform a free-text search for a course. The user will be able to specify which fields they want to search on. Data exporting * Ufi has a number of systems that will require exports of some of the data that will be held in CK2. The system will be able to generate these exports in an XML format. Administration * There will be an administration role where users, user groups and their permissions can be defined. * The administrator role will be able to define data sets that are used elsewhere in the system.

When the results from a previous = search are fed into this method an iterated list is produced but the pa value does not change either in = the onclick nor name positions There is no field in the actual database that would be suitable for = supplying a new value for each position. Is there a simple solution for this?? Any help appreciated. Remember that age and treachery will always triumph over youth and ability

I have bought the Zope Bible by Michael R .

I my z2.py file # The size of the thread pool, if ZODB3 is used. NUMBER_OF_THREADS=4 Does this mean I can only hace 4 instances <4 content authors users simultaneously using Zope>.

Browser-Check with getBrowser(): set global var for request or call it in every html-page
by Patrick Ulmer 27 Nov '03

27 Nov '03

Hi, i want to load different css for mozilla an explorer and found the nice function getBrowser() on zope.org. But know I don't know, what is possible or the better way to use it. 1.) my idea is to call it from my index.html and set a cookie or if possible a global var in zope for the request and use <dtml-if> for loading the css 2.) i use it to create the right css in a python script 3.) i call it in every html-header over <dtml-let> and use <dtml-if> for loading the right css what is the best to fit to zope? Thanks...Patrick
