我试图让我的模式包含一个可以将任务添加到待办事项列表的表单。我尚未对表格进行更改以使其正常工作。我只想让表单显示在我的模态上。
这是我正在制作的一个待办事项列表网站，我想要一个模式，我可以通过导航栏下拉菜单中的模式直接输入我的任务详细信息。
非常感谢任何帮助
views.py：

form = AddTaskForm()
return render(request, 'navbar.html', {'form': form})

我会尽力为您指明正确的方向，您可能已经知道......完成任务的方法不止一种。
首先，我会更改views.py：
class AddToDo(View):
def __build_context(self, form):
return {
'form': form,
# whatever else you need...
}
def __get_initial_parameters(self, request):
return {
# here you can initialize form dropdowns and other
# fields however you want them to appear when a user
# first visits the form/page (for instance your
# datetime fields could be prefilled with current
# date and time
}
def get(self, request):
request.session.setdefault('back_url',request.META.get('HTTP_REFERER'))
request.session['back_url'] =request.META.get('HTTP_REFERER')
form =AddTaskForm(initial=self.__get_initial_parameters(request))
context = self.__build_context(form)
return render(request, 'navbar.html', context)
def post(self, request):
form = AddTaskForm(request.POST,
initial=self.__get_initial_parameters(request))
if form.is_valid():
form.save()
return redirect(request.session['back_url'])
# Form was not valid, rebuild context
context = self.__build_context(form)
return render(request, 'navbar.html', context)
然后，更改您的表单，以便通过在元数据下方添加 init 来按照您想要的方式初始化它：
from django import forms
from django.forms import ModelForm
from .models import to_do
class AddTaskForm(ModelForm):
class Meta:
model = to_do
fields = ("title", "description", "created_on", "due_by")
def __init__(self, *args, **kwargs):
super().__init__(*args, **kwargs)
# since it sounds like you'll be assigning tasks with due # dates, you'll want to know when a task is being created
# and when a task is already created... I recommend using 'instance'
instance = getattr(self, 'instance', None)
if instance or instance.pk:
# this is for all forms... so task already exist.. important because you can lock fields this way to prevent users
# from changing things (i.e.)
self.fields['title'].label = 'Name your task'
self.fields['title'].required = True
self.fields['title'].readonly = True
# etc...
# do this with all your fields that you've included on your form... as you deem necessary
if not instance.pk:
# this is for the creation of Brand New Tasks...
self.fields['title'].label = 'Name your task'
self.fields['title'].required = True
self.fields['title'].readonly = False
# etc...
# do this with all your fields that you've included on your form... as you deem necessary
然后，在你的 urls.py 中：
from django.urls import path
from . import views
urlpatterns = [
path('', views.home, name='home'),
path('todo', views.to_do_list.as_view(), name='todolist'),
]
对于你的 html...我建议研究 django 的表单模板： https://docs.djangoproject.com/en/5.0/ref/templates/language/
我希望这有帮助。
