Hi again list,
I'm using webpy with great pleasure, in my little website, I let user insert
'words' in a table (see http://kate.homeunix.net/bayesfor/addword).
myform has validators, so that I make sure something is actually typed and
then after inserting I show something like "$word succesfully inserted",
this has been achieved with a form.Hidden since I couldn't find a better
way, is there a canonical way of doing it?
How I did it
website.py:
class addword:
def __init__(self):
# FIXME: check that word is not present yet before insert
self.myform = form.Form(
form.Textbox('word', form.notnull),
form.Hidden('hidden', **{'submitted': False}))
def GET(self):
print render.base( render.addword(self.myform()) )
def POST(self):
form = self.myform()
if not form.validates():
print render.base( render.addword(form) )
else:
form['hidden'].attrs['submitted'] = True
word = form['word'].value
web.insert('int_words', name=word)
print render.base( render.addword(form) )
templates/addword.html
$def with (form)
$if not form['hidden'].attrs['submitted']:
<h2>Add a word to the list of interesting ones</h2>
$if not form.valid:
<p class="error">Try again</p>
<form name="main" method="post">
$:form.render()
<input type="submit" value="submit" />
</form>
$else:
<h2>Word added</h2>
<p>
$form['word'].value has been succesfully added
</p>
<p>Click <a href="addword">here</a> if you want to add another
one</p>
I couldn't find a better approach on the wiki.
Thanks,
Matteo
