context of a for loop
by Fearless Froggie 07 Mar '03

07 Mar '03

Hi, When you are going through a for loop, are you in the context of that for loop variable? Can you drop out of that for loop context and into the context of the script? Example: If I loop through a list of id's with a for loop and do something to each of these objects, I get a "You are not allowed to access editMetadata in this context". Here's the code (here I'm just changing the title of each of my items in my list 'id' to 'bob'): for item in id: item_object = getattr(context, item) item_object.editMetadata(title='bob') But if I do these changes directly, it works fine: item_object = getattr(context, id[0]) item_object.editMetadata(title='bob') So I'm guessing that the for loops puts me into another context. How do I get into the context of the object I want to edit? I've tried "context.item_object.editMetadata(title='bob')" and "container.item_object.editMetadata(title='bob')", but they didn't work either. My script in all these cases is my custom skins directory. Many thanks for any ideas on this. (And thank you once again for all the great ideas I've received for my past emails :) Rita. __________________________________________________ Do you Yahoo!? Yahoo!

sending form data offsite
by Ed Colmar 07 Mar '03

07 Mar '03

Hi fellow zope hackers! I'm building a site for someone who wants to have the entire site within zope, to connect to dbs, etc... But they use a service that requires them to post form data to a master server. Is there an easy way (in dtml or python) to do this without seeing the data transfer or ending up at th other server's pages? So far I've considered making an external method that uses lynx and dumps the return data. Is this the best way? Thanks for the help! -ed- -- Green Graphics ::: Print and Web Design ::: 510.923.0000

squirting variable definitions into macros using fill-slot
by Felix Ulrich-Oltean 07 Mar '03

07 Mar '03

I have a macro like this: <metal:block define-macro="conf_form"> <div class="something" tal:define="chosen_thing request/chosen_thing|here/chosen_thing; the_name request/the_name|here/the_name"> <input type="radio" tal:attributes="name the_name; checked python:chosen_thing=='a' or nothing;" value="a" /> a <br /> <input type="radio" tal:attributes="name the_name checked python:chosen_thing=='b' or nothing;" value="b" /> b <br /> </div> </metal:block> I will be using it several times from the same template. I want to be able to pass in values for chosen_thing and the_name, but I can't think how. If I define a slot, e.g. for the <div>, the stuff in fill-slot will replace all the stuff in the macro. Alternatively, I could use fill-slot and a 'global' definition, but then I wouldn't be able to use it more than once. Am I just being dumb here? It must be possible to pass in dynamic information using fill-slot. Thanks for any advice, Felix.

If I run three sites at- www.mydomain.com intranet.mydomain.com extranet.mydomain.com And I map them to the following locations in my Zope using either VHM or siteroot- /www /intranet /extranet Will I still be able to accquire objects in the root container? For example, a shared database connection?

NuxUserGroups: workaround, anyone?
by baiewola＠netscape.net 07 Mar '03

07 Mar '03

My zope site is already created, and I did not create it with the idea that I would be implementing user groups. Therefore, I already have an acl_users folder at the top level of my site. All of my users are defined in that folder, and all access throughout the site is inherited, except for a few local roles assigned here and there. Now that I want to use NuxUserGroups, I have a problem: I cannot create groups at the top level. Since I already have an acl_users folder, I get an error when I try to create a "User Folder with Groups" at the root level. So I can't simply move all my existing users into a different type of user folder that supports groups. And when I create a "User Folder with Groups"at any other level, of course my users from my root level acl_users folder are not recognized so they cannot be added to groups. So if I want to add groups at any level, I have to re-create all my users. Does anyone have a workaround to this? Or am I overlooking a product that will let me do what I want (add groups to an existing site at the root level)? __________________________________________________________________ The NEW Netscape 7.0 browser is now available.

sending a post request to a secure site (paypal) from a python script/external method
by Richard Ettema 07 Mar '03

07 Mar '03

I'm trying to work out how to setup a python script and external method to post form data to a paypal https url. I basically want the user to click a button to pay for their selection which calls the python script, their order info is saved for our records, and then the external script passes onto paypal's secure server. Is this possible? The closest I have got this to work is the palpay page displayed with images missing, but not on a secure connection. I assume the images are missing because the url in the address bar is that of the python script, not the paypal url. Should I be doing something different than a read() in the ext. method? I have looked thru the examples in the urllib.py and urllib2.py but could not work out where I am going wrong, or if it is possible. I have seen comments about python must be built/installed with ssl support for secure connections to https urls, how do I work out if python was built/installed with this? Running: system: freebsd Zope: 2.5.1 python: 2.1.3 The python script: payBill ######### req = context.REQUEST form_dict = {} order_ref = context.recordOrder() form_dict['cmd'] = '_xclick' form_dict['business'] = 'test@test' form_dict['item_name'] = 'Services' form_dict['item_number'] = '%s' % order_ref form_dict['amount'] = '%.2f' % float(req['gdttl']) form_dict['return'] = '%s/services_thankyou' % req['URL'] form_dict['cancel_return'] = '%s/services_thanks' % req['URL1'] form_dict['no_note'] = 1 form_dict['currency_code'] = req['currency_code'] #send info to external method url_req = context.payBillExt( 'https://www.paypal.com/cgi-bin/webscr', form_dict ) return url_req ########## The External Method: payBillExt ######### import urllib2 import urllib def urlRequestCreation(self, url, data): """url""" url_data = urllib.urlencode( data ) url_req = urllib2.urlopen(url, url_data) return url_req.read() ######### Thanks for any pointers in the right direction.

Re: [Zope-dev] Stupid dtml-if comparision

It they're not the same type it'll never work. Unfortunately the type() built-in isn't available in DTML or Python scripts (if you go to an ExternalMethod you should be able to use it.) What you can try is this: str(i)==str(j) to compare the string representations or, if you're dealing with a certain type of number, int(i)==int(j) float(i)==float(j) In DTML, you have to call these from the namespace '_' (underscore) as so: _.str(i)==_.str(j) --jcc

Problem with Linux installation
by Yannis Lionis 06 Mar '03

06 Mar '03

Hi everybody. I'm attempting to install Zope 2.6.1 on Mandrake Linux version 9. I read the documentation and followed the instructions: unziped the files, run ./install, wrote down the login and password, set the sticky bit of /var and changed the owner of var to root (since I was installing as root), and used the ./zpasswd.py script to change the password to something more convenient, leaving the login name to 'admin'. Trouble starts here: The SETUPUID.TXT document file says I need to set the UID either in the ./z2.py, or in the ./start command line. I cannot do either! I tried the first option and typed: ./z2py -u admin What I got was the help list and at the bottom the following error messages: ./z2py: line 239: syntaxerror near unexpected token ' 0,' ./z2py: line 239: ' sys.path.insert(0,'%s/lib/python'%swhome)' So I thought I'd try the second option. I typed: ./start.py -u admin The process seemed to go fine (opened datanbase, mounted database, etc.) but a few seconds later I got a message: ERROR(200) z2 Can't find UID admin After experimenting a bit, I noticed that when I run ./start it deletes the 'inituser' file at some point during opening and mounting the database (as it appears anyway). So a few seconds later it looks for admin and finds nothing. Am I doing something wrong here? I have successfully done the whole thing in Windows 2000 (which of course is a different story, but still) and I can't find anything in the documentation that I'm doing wrong. I downloaded the zip file again and did the whole thing from the beginning and it made no difference, so it is not a corrupted file or anything like that. Can anyone help me on this? Thanks! Yannis P.S: And sorry for the huge email, I just thought that nobody can really help unless they have some details... --------------------------------- Do you Yahoo!? Yahoo!
