[Zope] Fetching data from external methods
Hi! I've been trying almost two weeks with this problem. I have read 'tons' on zope documentation and mailing lists. I have this dtml form, which submits two values to external method. External method searches LDAP directory with submitted values and returns an object(class) with 5-30 values. I know only how to return plain text to Zope (return obj.__dict__ or return obj.value1). How i return those values in zope and embed those values into dtml file. I have some kind of clue, how i want to do this (or do i?): can i make Zclass and return values into that and call Zclass variables in dtml? in fact only problem here is how i return values from external method like obj.value1 , obj.value2 into zope and use them in dtml or/and in Zclass instances. Please, somobody save my nerves and help me figure solution with this problem.

RE: [Zope] Fetching data from external methods
sorry but your example did'nt work:
in external method:
return (obj1, obj2,)
in DTML:
dtml-in external_method(your,params)
dtml-var value1
dtml-var value2
/dtml-in
here is my submit forms code to explain my case
form action="LDAPsearch" method=POST ENCTYPE="multipart/form-data"
cn: br
input name="cn" size="10"br
objectclass: br
input name="objectclass" size="15"brbr
input type="SUBMIT" name="send" value=" Search "
/form
LDAPsearch is my external method (object in zope which points to .py module)
My method outputs are:
res = (contains search result using forms input values)
sn = res.sn (one of the values in res-object)
return sn
and i try to embed in dtml like this
dtml-in "LDAPsearch('66','*',REQUEST)"
dtml-var sn
/dtml-in
Zope returns error:
Error Type: InError
Error Value: Strings are not allowed as input to the in tag.
if i try to return
res.__dict__ in external method
zope returns this kind of error:
Error Type: KeyError
Error Value: 0
this works
dtml-var "LDAPsearch('66','*',REQUEST)"
but it lefs me with two problems
1) how i can input values in LDAPsearch(how i input here)
2) i don't have any control of return value, it returns list like
this
('Ukko', '66', 'oEmail')
If you are submitting to your external method from an HTML form, you
will need to return the HTML to be
def my_external_method(self,param1,param2):
...do stuff...
string = 'HTMLBODY'
string = string + ...render your results here...
string = string + '/BODY/HTML'
return string
this solution worked, but it's not what i really want to do. I don't want
include return HTML-file in my python script, like in that example.

RE: [Zope] Fetching data from external methods
FINALY, your code sould look like:
In externalMethod:
return res
#ENTIRE obj
DTML code:
dtml-let resDTML="LDAPsearch('66','*',REQUEST)"
dtml-var "resDTML.cn"
dtml-var "resDTML.otherAttributes"
/dtml-let
yeah, thanks a lot, it works, but i have still a liitle problem
this might sound like newbie question ( but i don't really know)
how i can dtml-res with input values like this
dtml-let resDTML="LDAPsearch(myinput,myinput2,REQUEST)"
myinput is data that i can type like search criteria in my
search-form
should i make somekind on handler-DTML? which picks up submitted
datafrom my submitted form and puts them in dtml-let?

^
that should be 'return res'
...then the following will work:
dtml-in "LDAPsearch('66','*',REQUEST)"
dtml-var sn
/dtml-in
this works
dtml-var "LDAPsearch('66','*',REQUEST)"
...because that displays sn, which is what you're returning!
1) how i can input values in LDAPsearch(how i input here)
Don't understand what you want here...
2) i don't have any control of return value, it returns list like
this
('Ukko', '66', 'oEmail')
you should be able to dtml-in over whatever is returning that...
