Re: [Zope] sql query results - DTML method problem
"Manuel Amador (Rudd-O) writes: #8 dtml-in expr=\"findClassTitle(code=52.139)\" RING: dont do that, dtml wont work in python namespace instead, remember that in python namespace all vars present in dtml namespace are inherited. I do not see a reason, why not to use this (except, that " should not be escaped, of cause). do this: dtml-in expr=\"findClassTitle(code=_.(\'class_code\'))\" the __.() construct is required since underscore arent allowed in python variable names. if the var was called classcode, you could do "_" are allowed in Python names. They are treated in the same way as a letter. DTML restricts the use of "_": A name must not *START* with an "_" (unless it is the special name "_"). Inside name, you can use "_" freely. dtml-in expr=\"findClassTitle(code=classcode)\" dats it. That said, you can also use: dtml-in expr="findClassTitle(code=class_code)" dtml-in expr=\"findClassTitle(code=dtml-var class_code)\" *** syntax error I agree with Manuel: you cannot nest DTML. And it is this nesting, that triggered his "RING: do not do that!" Use: dtml-in expr="findClassTitle(code=class_code)" I.e. you can simply use the name of the variable. Manuel is right, too, that DTML allows much more characters in names than Python does. If you have a name with a character forbidden in Python names, such as e.g. a "-", then you can use "_[name]" or "_.getitem(name)" (as Manuel said). It is only, that "_" (unlike "-") is allowed in Python names.

Re: [Zope] sql query results - DTML method problem
#8 dtml-in expr="findClassTitle(code=52.139)"
you might wanna try
either dtml-in expr="findClassTitle(code=_['class_code'])"
or dtml-in expr="findClassTitle(code=_.getitem('class_code'))"
dtml-in expr="findClassTitle(code=dtml-var class_code)" *** syntax
error
regards.

Re: [Zope] sql query results - DTML method problem
Quoting Lee Reilly CS1997 [EMAIL PROTECTED]: Hi, I have a TINY problem, which I think there is a simple solution too... but for the life of me, I can\'t find it! I\'d be grateful if someone could point me in the right direction. I have a database setup containing details of classes, students lecturers. The user is prompted to enter a class code (a unique key) which is used to query the database and return the class title. Simple. A DTML method prompts me for the class code -- I enter 52.139 and it posts to a method \'enterClassCodeAction\', below. #1dtml-var standard_html_header #2h2Confirm/h2 #3pYou entered idtml-var class_code/i/p #4 #5p #6Our records show that dtml-var class_code is called #7 #8dtml-in expr=\"findClassTitle(code=52.139)\" RING: dont do that, dtml wont work in python namespace instead, remember that in python namespace all vars present in dtml namespace are inherited. do this: dtml-in expr=\"findClassTitle(code=_.(\'class_code\'))\" the __.() construct is required since underscore arent allowed in python variable names. if the var was called classcode, you could do dtml-in expr=\"findClassTitle(code=classcode)\" dats it. #9dtml-var title #10 /dtml-in #11 #12 #13 /p #14 dtml-var standard_html_footer ^ The method works fine when the class code is manually inserted (line #8) but when I try to pass the variable from the previou post, held in dtml-var class_code I have probs. dtml-in expr=\"findClassTitle(code=dtml-var class_code)\" *** syntax error findClassTitle is a ZSQL method for returning the class title given a class code: select title from classes where dtml-sqltest code op=eq type=float Hmm... anyone see the problem?
