I wanted to mark rows with an erroneous input with 'class="error"' and move the errorlist below the input tag so I wrote a NormalRowFormatter which behaves like a format string by overwriting __mod__.
Examples:
class MyForm(PrettyBaseForm, forms.Form):
# add your fields here
SomethingForm = form_for_model(Something, form=PrettyBaseForm)
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 | from django import newforms as forms
class PrettyBaseForm (forms.BaseForm):
class NormalRowFormatter(object):
def _error_class(self, errors):
if errors:
return ' class="error"'
else:
return ''
def __mod__(self, d):
return u'<tr%s>' % self._error_class(d['errors']) \
+ u'<th>%(label)s</th><td>%(field)s%(errors)s%(help_text)s</td></tr>' % d
def as_table(self):
return self._html_output(
PrettyBaseForm.NormalRowFormatter(),
u'<tr><td colspan="2">%s</td></tr>', # unused
u'</td></tr>',
u'<br />%s',
False
)
