[SQLObject] FormEncode

[Michel T. <mic...@ya...>]

Hi guys!

Ian, after the recent thread about form validation I think to try
FormEncode, I used and still use FunFormKit for my projects, I use the
FFK form generation and I confess it limitates my possibilities.

I like the way htmlfill work, I tried to make a validator to a form
with sucess, my only problem was when I try to use htmlfill. I will put
my code on the end of message.

I must question you that are using FormEncode with Webware, what is the
best way to work with the two packages? I think in a way:

First I will check for errors in the writeHTML method, if the form was
processed and there is an error, I will define an attribute with this
error. If there is no error, I can call a formProcessed function...

Then I should write the content of the page, the form is part of the
page (using self.write to write it). I want to trigger the page
writing, I want to get the content before write and then parse it with
htmlfill, filling default values and error messages. Does anyone know
how can I trigger the page writing? I use a subclass of the Cheetah's
Template, not Page.

Sorry any english mistake, my htmlfill try are the follow:

#:: FormEncode test...
from validator.schema import Schema
from validator import validators
from validator import htmlfill

class MyValidator(Schema):
  name=validators.String(not_empty=True)
  age=validators.Int()

form='''\
<form method="post">
<table>
<tr>
  <td>Name: <form:error name="name"></td><td><input type="text"
name="name"></td>
  <form:iferror name="name">mndfnaofdas</form:iferror>
</tr>
<p><input type="submit" name="_action_send" value="Send Data"></p>
</form>'''

userInput={'name':'michel', 'age':20}

errorDict={}
try:
  userInput=validators.to_python(MyValidator, userInput)
except validators.Invalid, error:
  errorDict=error.error_dict

parser=htmlfill.FillingParser(userInput, errors=errorDict)
parser.feed(form)
print parser.text()
parser.close()

...

I get the follow error:

Traceback (most recent call last):
  File "teste.py", line 29, in ?
    parser.feed(form)
  File "/usr/lib/python2.3/site-packages/validator/htmlfill.py", line
68, in feed
    HTMLParser.HTMLParser.feed(self, data)
  File "/usr/lib/python2.3/HTMLParser.py", line 108, in feed
    self.goahead(0)
  File "/usr/lib/python2.3/HTMLParser.py", line 150, in goahead
    k = self.parse_endtag(i)
  File "/usr/lib/python2.3/HTMLParser.py", line 329, in parse_endtag
    self.handle_endtag(tag.lower())
  File "/usr/lib/python2.3/site-packages/validator/htmlfill.py", line
127, in handle_endtag
    self.handle_end_iferror()
TypeError: handle_end_iferror() takes exactly 2 arguments (1 given)

Thanks for any help!
