Hi!
(Tried this on the webware-discuss-list. Didn't find this list at first)
I'm trying to put several forms on one page, each with it's own submit
button. I run into an Exception when using a validator:
FormError: Upon error you must render the form that caused the error -- form addistrictform had an error and you tried to render addareaform
Here's my servlet:
--snip--
from Lib.SecurePage import SecurePage
from Cheetah.Template import Template
from FunFormKit.Form import FormDefinition, FormServlet
from FunFormKit import Field
from FunFormKit.Validator import FormValidator, ValidatorConverter, \
InvalidField
from Lib.Validators import ServletValidator
class DistrictValidator(ServletValidator):
def convert(self, districtid):
try:
num_districtid = int(districtid)
except ValueError:
raise InvalidField, self.servlet.setting('MustBeNumberMessage')
district = self.servlet.getDistrict(num_districtid)
if district is None:
return num_districtid
else:
raise InvalidField, \
self.servlet.setting('DistrictNumberTakenMessage')
class SystemConfig(SecurePage, FormServlet):
def __init__(self):
SecurePage.__init__(self)
areaForm = FormDefinition('SystemConfig', 'writeForm',
[Field.TextField('areaname', maxLength=255,
size=25),
Field.TextField('lettercode', maxLength=2,
size=2),
Field.SubmitButton('submit',
methodToInvoke='addarea')],
name="addareaform")
districtForm = FormDefinition('SystemConfig', 'writeForm',
[Field.TextField('districtname',
maxLength=255,
size=25),
Field.TextField('shortname', maxLength=255,
size=5),
Field.TextField('districtid', maxLength=2,
size=2,
validators=\
[DistrictValidator(self)]),
Field.SubmitButton('submit',
methodToInvoke=\
'addistrict')],
name="addistrictform")
FormServlet.__init__(self, 'writeContent', [areaForm, districtForm],
defaultFormDefinition=areaForm)
def addarea(self, fieldDict):
self.addArea(fieldDict["lettercode"], fieldDict["areaname"])
self.response().sendRedirect("SystemConfig")
def addistrict(self, fieldDict):
self.addDistrict(fieldDict["districtid"],
fieldDict["shortname"], fieldDict["districtname"])
self.response().sendRedirect("SystemConfig")
def awake(self, trans):
SecurePage.awake(self, trans)
if trans.request().hasField("deletearea"):
self.deleteArea(int(trans.request().field("deletearea")))
self.response().sendRedirect("SystemConfig")
if trans.request().hasField("deletedistrict"):
self.deleteDistrict(int(trans.request().field("deletedistrict")))
self.response().sendRedirect("SystemConfig")
def title(self):
return 'Konfiguration av FUFReg'
def defaultConfig(self):
secConf = SecurePage.defaultConfig(self)
secConf.update({'RequiredLevel':400})
return secConf
def writeForm(self):
areas = self.getAreas()
districts = self.getDistricts()
areaRF = self.renderableForm('addareaform')
districtRF = self.renderableForm('addistrictform')
t = Template(file=self.getTemplateName("SystemConfig"),
searchList = [{'areas':areas, 'areaRF':areaRF,
'districts':districts,
'districtRF':districtRF}])
self.write(str(t))

(The ServletValidator class looks like this:
class ServletValidator(ValidatorConverter):
def __init__(self, servlet):
ValidatorConverter.__init__(self)
self.servlet = servlet
SecurePage inherits from SitePage that inherits from SidebarPage and
MiscUtils.Configurable - If you need more code for debugging, just
tell me)
The template looks like this:
--snip--
## mode: html
<H1>Landsting och deras kommuner</H1>
Klicka på Landstinget namn för att se och editera dess kommuner.
<table>
<tr>
<th align="left">Länsbokstav</th><th align="left">Landsting</th>
</tr>
#for $row in $areas
<tr>
<td align="left">${row.lettercode}</td>
<td align="left"><a href="SubAreaConfig?area=$row.id">${row.name}</a></td>
<td align="left">
#if 0 == $row.noofsubareas and 0 == $row.noofsubsocieties
<a href="SystemConfig?deletearea=$row.id">Radera</a>
#else
<font color="grey">Kan ej raderas</a>
#end if
</tr>
#end for
</table>
Om ett landsting ej kan raderas beror det på att det finns föreningar
eller kommuner som beror på detta landsting.
<H3>Lägg till landsting</H3>
${areaRF.start}
<TABLE>
<tr>
<td align="right" valign="top" class="label">
<b>Bokstavskod:</b></td>
<td>${areaRF.lettercode} ${areaRF.lettercode.error}</td>
</tr><TR>
<td align="right" valign="top" class="label">
<b>Namn:</b></td>
<td>${areaRF.areaname} ${areaRF.areaname.error}</td>
</tr><tr>
<td> </td>
<td align="left" valign="top">
<input type="hidden" name="submit" value="submit">
<input type="submit" name="submit" value="Lägg till">
</td>
</tr>
</TABLE>
${areaRF.end}
<H1>Distrikt</H1>
<table>
<tr>
<th align="left">Nummer</th>
<th align="left">Förkortning</th>
<th align="left">Namn</th>
</tr>
#for $row in $districts
<tr>
<td align="left">${row.id}</td>
<td align="left">${row.shortname}</td>
<td align="left">${row.name}</td>
<td align="left">
#if 0 == $row.noofmembers and 0 == $row.noofsubsocieties
<a href="SystemConfig?deletedistrict=$row.id">Radera</a>
#else
<font color="grey">Kan ej raderas</a>
#end if
</tr>
#end for
</table>
<P>
Om ett distrikt ej kan raderas beror det på att det finns föreningar
eller distriktsmedlemmar i distriktet.
<H3>Lägg till distrikt</H3>
${districtRF.start}
<TABLE>
<tr>
<td align="right" valign="top" class="label">
<b>Nummer:</b></td>
<td>${districtRF.districtid} ${districtRF.districtid.error}</td>
</tr><TR>
<td align="right" valign="top" class="label">
<b>Förkortning:</b></td>
<td>${districtRF.shortname} ${districtRF.shortname.error}</td>
</tr>
<TR>
<td align="right" valign="top" class="label">
<b>Namn:</b></td>
<td>${districtRF.districtname} ${districtRF.districtname.error}</td>
</tr>
<tr>
<td> </td>
<td align="left" valign="top">
<input type="hidden" name="submit" value="submit">
<input type="submit" name="submit" value="Lägg till">
</td>
</tr>
</TABLE>
${districtRF.end}
--snap--
(Might be less understandable if you don't know swedish :) )
The 'defaultFormDefinition' argument is confusing me - perhaps
FunFormKit can only do one form per page at a time? Or am I doing
something else wrong? The forms both render nicely and work as they
should, except for errorhandling.
Regards,
\EF
