I want to add a verify code field in the login form.
So, I write a authentication_form which added a charField to generate a
verify code and the verify code saved to the request.session.
But When I send login form request,I find in my authentication_form, I can't
campare the session's verify code and the clean_data["verifycode"],
Because the request in Null when invoke my authentication_form.
code below and the question in line highlighted like *###HERE*
class MyAuthenticationForm(AuthenticationForm):
verifyimg=forms.CharField(label="verifycode",widget=vericonf.CaptchaWidget)
def __init__(self, request=None,*args, **kwargs):
self.request=request
kwargs_new = {'error_class': DivErrorList}
kwargs.update(kwargs_new)
#elf.error_class = DivErrorList
super(MyAuthenticationForm,self).__init__(*args, **kwargs)
def as_div(self):
"Returns this form rendered as HTML div."
return self._html_output(
normal_row = u'<div%(html_class_attr)s
style="float:left;"><div class="formlabel">%(label)s</div><div
class="formfield">%(field)s%(help_text)s</div><div
class="formerror">%(errors)s</div></div>',
error_row = u'<div>%s</div>',
row_ender = u'</div></div>',
help_text_html = u'<div style="float:left;"><span
class="helptext">%s</span></div>',
errors_on_separate_row = False)
def clean_verifyimg(self):
pass
def clean(self):
vericode=""
username = self.cleaned_data.get('username')
password = self.cleaned_data.get('password')
if self.request and self.request.session and
self.request.session.get("verifyimg"):
vericode = self.request.session.get("verifyimg")
print vericode *###HERE request.session is Null then I can't
compare vericode and verify now.How to do it?*
verify=self.cleaned_data.get('verifyimg')
print verify
if username and password:
self.user_cache = authenticate(username=username, password=password)
if self.user_cache is None:
raise forms.ValidationError(_("Please enter a correct
username and password. Note that both fields are case-sensitive."))
elif not self.user_cache.is_active:
raise forms.ValidationError(_("This account is inactive."))
if verify and vericode:
if verify != vericode:
raise forms.ValidationError("verify code is wrong.pls
Try again!")
self.check_for_test_cookie()
return self.cleaned_data
