dict_char='.', list_char='-', post_only=True, state=None,
on_get=False, **htmlfill_kwargs):
"""Validate input either for a FormEncode schema, or individual
validators
Given a form schema or dict of validators, validate will attempt to
validate the schema or validator list.
If validation was successful, the valid result dict will be saved
as ``self.form_result``. Otherwise, the action will be re-run as if
it was a GET, and the output will be filled by FormEncode's
htmlfill to fill in the form field errors.
``schema``
Refers to a FormEncode Schema object to use during validation.
``form``
Method used to display the form, which will be used to get the
HTML representation of the form for error filling.
``variable_decode``
Boolean to indicate whether FormEncode's variable decode
function should be run on the form input before validation.
``dict_char``
Passed through to FormEncode. Toggles the form field naming
scheme used to determine what is used to represent a dict. This
option is only applicable when used with variable_decode=True.
``list_char``
Passed through to FormEncode. Toggles the form field naming
scheme used to determine what is used to represent a list. This
option is only applicable when used with variable_decode=True.
``post_only``
Boolean that indicates whether or not GET (query) variables
should be included during validation.
.. warning::
``post_only`` applies to *where* the arguments to be
validated come from. It does *not* restrict the form to
only working with post, merely only checking POST vars.
``state``
Passed through to FormEncode for use in validators that utilize
a state object.
``on_get``
Whether to validate on GET requests. By default only POST
requests are validated.
Example::
class SomeController(BaseController):
def create(self, id):
return render('/myform.mako')
@validate(schema=model.forms.myshema(), form='create')
def update(self, id):
# Do something with self.form_result
pass
