This is a general problem for zope service providers and their users; I wonder how we can resolve it ? Related, though specific to Codeit users: I need to pack to avoid the above, but fear the data-corrupting packing bugs which were fixed in more recent versions of zope. Codeit, perhaps time for an upgrade ? At least to 2.1.6 ? Best regards -Simon

Encoding URL Vars
by Kapil Thangavelu 22 Jul '00

22 Jul '00

i recently had a problem with encoding url vars in a dtml-call such as <dtml-call "RESPONSE.redirect(URL1+'?var_name='+var_name)"> i got a couple suggestions from the list but decided that i'd go ahead and write a utility function in a python method based on urllib. here are two python methods. one to encode a dictionary and one to automatically encode all the form variables in the request. you still need to add a '?' to the url before a call to the method to signify a GET. Python Method ##1 name: url_encode_vars parameters: vars # a dictionary of variables to be encoded # Code straight from urllib minor # changes to get around assignment to sub_scripts, # access to string module, and namepace issues global always_safe, quote, quote_plus always_safe = _.string.letters + _.string.digits + '_,.-' def quote(s, safe = '/'): global always_safe safe = always_safe + safe res = [] for c in s: if c not in safe: res.append('%%%02x'%ord(c)) else: res.append(c) return _.string.joinfields(res, '') def quote_plus(s, safe='/'): global quote if ' ' in s: res = [] # replaec ' ' with '+' l = _.string.split(s, ' ') for i in l: res.append(quote(i, safe)) return _.string.join(res, '+') else: return quote(s, safe) def urlencode(dict): global quote_plus l = [] for k, v in dict.items(): k = quote_plus(str(k)) v = quote_plus(str(v)) l.append(k + '=' + v) return _.string.join(l, '&') return urlencode(vars) #### example call to above <dtml-call "RESPONSE.redirect(URL1+'?'+url_encode_vars({vars={'squishy':1, 'bad_input':'&user=root'}) )"> this isn't always optimal since you might not know all the variables and you just want to pass along all of the form variables. hence PythonMethod #2 name: url_encode_form_vars parameters: namepace # the namepace='_' try: vars=namespace['REQUEST'].form method = namespace.getitem('url_encode_vars', 0) return method(vars) except: pass ##### example call to above <dtml-call "RESPONSE.redirect(URL1+'?'+url_encode_form_vars(_))"> Cheers Kapil

A Better Way (Stupid DTML code)
by Dennis Baker 22 Jul '00

22 Jul '00

Ok, there has to be a better way of doing this, I just want to show a dialog if there minimum value of a field is lower than 20,000. This is the only way I could figure out to do this, Python seems to choke on variables with Hyphens so I have to use the dtml-let.... It works but it's a STUPID way to do things. <dtml-in SQL_list_providers> <dtml-let min_provid=min-provid> <dtml-if "min_provid < '20000'"> <dtml-if sequence-start> <h3>Search for Member Information</H3>  <dtml-var MemberSearchForm> </dtml-if> </dtml-if> </dtml-let> </dtml-in>

How to require an @ symbol in email form field??
by Stacy Formby 21 Jul '00

21 Jul '00

Hello, I am new to Zope; since our webmaster left I'm trying to make small changes to the website. We have a standard registration form that collects information from users (first name, last name, email, company name, etc.) All of the fields are required, except address 2, address3. Great. fine. If the user doesn't fill out a field, they get an alert. But they can fill each field out with gibberish--as long as there is a character in the input, we accept it. Is there a way to require at least an "@" sign in the email field? The powers that be think this would be useful. Here's the form processing code as it stands today. Any help is appreciated. Sformby  <dtml-in required> <dtml-comment> The length of the following expr is due to the fact that some types of form elements (e.g. text) always create a var, while others (e.g. radio) don't. </dtml-comment> <dtml-unless expr="REQUEST.form.has_key(_['sequence-key']) and REQUEST.form[_['sequence-key']]"> <dtml-call request.set(missing_fields1)"> </dtml-unless> </dtml-in>  <dtml-if request.has_key(missing_fields')"> The following input fields are required and have not been filled out:  <ul> <dtml-in required> <dtml-unless expr="REQUEST.form.has_key(_['sequence-key']) and REQUEST.form[_['sequence-key']]"> <li><dtml-var sequence-item> </dtml-unless> </dtml-in> </ul> Please click on your browser's "Back" button to update your information, or <a href="registration.html">click here</a> to start over. <dtml-else>

zope.org down
by ethan mindlace fremen 21 Jul '00

21 Jul '00

Well, folks, zope.org is down again, because the site was packed without enough space on the device. because the error is relatively subtle, I'm restoring from yesterday's backup, so please check to be sure that everything you've done recently is preserved. To keep this from happening again, we will be adding an additional 40gb drive that should do us just fine until the Data.fs hits 2 GB. Sorry for the downtime, -- ethan mindlace fremen Zopatista Community Liason Abnegate I!

RE: [Zope] URL quoting in python
by Chris McDonough 21 Jul '00

21 Jul '00

I often create an external method for this... em: def url_quote(s): import urllib return urllib.quote_plus(s, safe='') Silly, but it works. I think the alternative is to hack the DT_Util.py module in the DocumentTemplate directory to expose urllib or a derived function. > -----Original Message----- > From: Kapil Thangavelu [mailto:kvthan@wm.edu] > Sent: Wednesday, July 19, 2000 11:46 PM > To: zope(a)zope.org > Subject: [Zope] URL quoting in python > > > is there a way to get a url-encoded/quoted variable in > pythonish dtml ? > > what i am trying to do > <dtml-call "RESPONSE.redirect(URL1+'?foo_bar='+foobar)"> > > > Kapil > > _______________________________________________ > Zope maillist - Zope(a)zope.org > http://lists.zope.org/mailman/listinfo/zope > ** No cross posts or HTML encoding! ** > (Related lists - > http://lists.zope.org/mailman/listinfo/zope-announce > http://lists.zope.org/mailman/listinfo/zope-dev ) >

Then you can use whatever IP/DNS > load balancing tool your heart desires. I think most people seem to be missing the point here. The idea is that ALL servers can serve ALL content. HOWEVER, the 'load balancer' will opt for a certain server for a certain URL, in order to improve cache hits. So, for www.contrived-example.com/dir1 it will first try server1, but if it's busy (or down) it will try others. This way, the cache on server1 is more likely to contain objects relevant to /dir1 and thus have a higher hit rate, therefore improving performance. An enforced 'mapping', as you were suggesting, removes ALL redundancy from the site, but would likely provide even better cache hits. > a thought, Have a better one, Curtis

I could add 1 to the date but then I would get other problems on my site which is not good. I have reported the bug now and I hope they can resolve it quickly.
