[英]Django crispy forms - VariableDoesNotExist
我試圖在http://django-crispy-forms.readthedocs.org/en/latest/crispy_tag_forms.html上完成本教程
當我嘗試打開頁面時,出現以下錯誤;
VariableDoesNotExist at / Failed lookup for key [example_form] in u
它嘗試查找example_form,但找不到它。 因為我真的是django和python的新手,所以我迷失了缺少的部分。 在這種情況下我還需要一個views.py還是可以直接從urls.py引用表格?
我的urls.py
urlpatterns = patterns('',
url(r'^$', 'ian.views.home', name='home'),
url(r'^admin/', include(admin.site.urls)),
)
我的views.py
def home(request):
return render_to_response("index.html",
context_instance=RequestContext(request))
我的forms.py
from crispy_forms.helper import FormHelper
from crispy_forms.layout import Submit
class ExampleForm(forms.Form):
like_website = forms.TypedChoiceField(
label = "Do you like this website?",
choices = ((1, "Yes"), (0, "No")),
coerce = lambda x: bool(int(x)),
widget = forms.RadioSelect,
initial = '1',
required = True,
)
favorite_food = forms.CharField(
label = "What is your favorite food?",
max_length = 80,
required = True,
)
def __init__(self, *args, **kwargs):
super(ExampleForm, self).__init__(*args, **kwargs)
self.helper = FormHelper()
self.helper.form_id = 'id-exampleForm'
self.helper.form_class = 'blueForms'
self.helper.form_method = 'post'
self.helper.form_action = 'submit_survey'
self.helper.add_input(Submit('submit', 'Submit'))
我的index.html
{% load crispy_forms_tags %}
{% crispy example_form example_form.helper %}
您永遠不會將表單實例傳遞給視圖的渲染器。
非常簡單地至少看到您的表單已呈現...
def home(request):
example_form = ExampleForm()
return render_to_response("index.html",
{"example_form": example_form},
context_instance=RequestContext(request))
您將需要查看django文檔,以了解如何處理從表單等返回的數據,但這將使您能夠看到呈現在頁面上的數據。
