I'm trying to build a better/more powerful form class for Django. It's working well, except for these sub-forms. Actually, it works perfectly right after I re-start apache, but after I refresh the page a few times, my HTML output starts to look like this:
<input class="text" type="text" id="pickup_addr-pickup_addr-pickup_addr-id-pickup_addr-venue" value="" name="pickup_addr-pickup_addr-pickup_addr-pickup_addr-venue" />
The pickup_addr- part starts repeating many times. I was looking for loops around the prefix code that might have cause this to happen, but the output isn't even consistent when I refresh the page, so I think something is getting cached somewhere, but I can't even imagine how that's possible. The prefix car should be reset when the class is initialized, no? Unless it's somehow not initializing something?
class Form(object):
count = 0
def __init__(self, data={}, prefix='', action='', id=None, multiple=False):
self.fields = {}
self.subforms = {}
self.data = {}
self.action = action
self.id = fnn(id, 'form%d' % Form.count)
self.errors = []
self.valid = True
if not empty(prefix) and prefix[-1:] not in ('-','_'): prefix += '-'
for name, field in inspect.getmembers(self, lambda m: isinstance(m, Field)):
if name[:2] == '__': continue
field_name = fnn(field.name, name)
field.label = fnn(field.label, humanize(field_name))
field.name = field.widget.name = prefix + field_name + ife(multiple, '[]')
field.id = field.auto_id = field.widget.id = ife(field.id==None, 'id-') + prefix + fnn(field.id, field_name) + ife(multiple, Form.count)
field.errors = []
val = fnn(field.widget.get_value(data), field.default)
if isinstance(val, basestring):
try:
val = field.coerce(field.format(val))
except Exception, err:
self.valid = False
field.errors.append(escape_html(err))
field.val = self.data[name] = field.widget.val = val
for rule in field.rules:
rule.fields = self.fields
rule.val = field.val
rule.name = field.name
self.fields[name] = field
for name, form in inspect.getmembers(self, lambda m: ispropersubclass(m, Form)):
if name[:2] == '__': continue
self.subforms[name] = self.__dict__[name] = form(data=data, prefix='%s%s-' % (prefix, name))
Form.count += 1
Let me know if you need more code... I know it's a lot, but I just can't figure out what's causing this!
