Re: [Zope] Frustrated with Python and Frameworks. Zope, Grok, Django, CherryPy

I’ve also Perhaps web.py can interest you then? Its not very much of framework (you actually write everything in Python, even making your own architectural decisions, and template language resembles Python also), but it requires almost no learning and dynamic site can be setup in no time. And webpy is not too hard as it is very minimalistic, so enjoy writing Python most of the time instead of working around some framework's peculiarities. Maybe after at least playing with that you will revisit other Python web application frameworks already knowing what you want. Regards, Roman Susi looked at templating languages like Spyce, and Cheetah. I’m beginning to think there’s nothing out there for a newbie python programmer like myself. I’m a Network Admin that likes programming but doesn’t have the time to get really proficient at it. I selected Python as a language of choice and that’s all I’ve used. I’ve written a few scripts . I’m interested in building dynamic web sites but I tell you it’s impossible to select a tool. I’ve researched all the tools mentioned above. The most important thing in my decision is that I know some Python and want to use it to build the dynamic site. I don’t want to learn a new language to do that. ZPT is a new language. Its not python. Not even close. Out of all the ones I’ve researched I like Zope 2 the best. Not sure why. I want some thing easy. I like DTML. It’s easy. I know why ZPT has it’s advantages but for ease of use it doesn’t come close to DTML. Most people like me wont be building complex web sites and I’d be the only working on it meaning I’ll do the HTML layout and code the dynamic portions of it. So I don’t’ need to worry about an HTML editor getting confused with the dynamic languages mixed in blah blah blah. I’m afraid to learn Zope 2 because I have no idea what direction it’s going in. Not to mention I don’t particularly like ZPT. I’ve read DTML isn’t going anywhere but I don’t imagine I’ll get much support on it when needed and I’m sure people will be telling me to use ZPT cause DTML is dead. Funny, I read something while reading news about Grok’s new plugins for any template language . They used Genshi as an example and talked about template languages and which one is better etc.. The bottom line was use the one that you like. So I wish people would stop putting down DTML or others over the one they prefer and continue to help those regardless of which they choose. Back to trying to choose. I think Django is too hard. I like Mod_python with PSP. PSP seems to be more python like then anything I’ve seen. Yet Mod_Python has terrible docs for people like me and it doesn't seem to popular. The other frameworks have some good ideas. I like Karrigell but you just don’t know how long it will be supported.Gluon is cool but its new. Zope 3 is out of the question. Grok looks to me like another CherryPy. It may be easier the Zope 3 but it’s not easier then Zope 2. Plus I’ve yet to get it installed on my windows XP to play. I like cheetah as a tool. There docs are not that great and not many examples. Plus no auto generated content like you get in Zope 2. Yes some magic is good. The CRUD is what made Rails over rated to start out with.People like some magic. saves time. Combining Cheetah and Zope sounds interesting to me. So what do I do. I like Zope 2. I can’t find any books on it released after 2002. Plone is tooo much. There aren’t any new products out for Zope 2 and the ones that are there haven’t been touched for years. Zope 2 wiki seems dead. I was looking the other day for some type of auto CRUD for Zope 2. couldn’t find anyting. No one seems to be adding anything new to Zope 2 which scares me the most. If I take the time to learn a tool I want to make sure it’s going to be around for awhile and have good support and new addons being added all of the time to help me. ___ 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 ) !DSPAM:474b8277286491564115247! ___ 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 )
[Zope] ordinal not in range error in StringIO.py
hi! My code produces the following traceback File /opt/Zope-2.9.1/lib/python/ZPublisher/Publish.py, line 40, in call_object result=apply(object,args) # Type scr to step into published object.

I have analysed self.buflist and it seems that unicode strings are mixed with usual strings. Unicode strings come from .mo file. So, the question is why ZPublisher doesnt coerce different string before serving and what can I do in this situation? .po file has utf8 encoding. Publisher encoding is utf8. Quick and very dirty solution is to mend StringIO.py... Does anybody has better cure? Thanks!

Chris, could you put this into Zope issue tracker (with security tick as I do not want to make this info public right now)? (I've tried but I do not have an account there..) No, there's nothing stopping you registering at zope.org and doing this yourself. Furhtermore, I'd guess this is likely a bug in your code and nothing to do with Zope ;-) (of course, I could be wrong on that, but I haven't seen any evidence yet) Even if it is in my code, it is still too bad to get down the whole Zope server.
