Django:当主页已经有模板时，如何在主页中添加另一个表单

Question

在我的主页上(http://127.0.0.1:8000/)我在views.py中创建了一个模板及其功能，主页的URL指向它，然而，我也想在主页上显示一个表单。

views.py:

def index(request):
template = loader.get_template('tracker/index.html')
hours_grouped_project = 
LogHours.objects.all().order_by('proj_assignment__project__name', 'day')
context = {
'hours_grouped_project':hours_grouped_project,
}
return HttpResponse(template.render(context,request))
def form(request):
if request.method== 'POST':
form = LogHoursForm(request.POST)
if form.is_valid():
day = form.cleaned_data['day']
hours = form.cleaned_data['hours']
developer = form.cleaned_data['developer']
project = form.cleaned_data['project']
proj_assignment=ProjectAssignment.objects.create(
developer=developer,project=project)
LogHours.objects.create(day=day,hours=hours, 
proj_assignment= proj_assignment)
else:
form = LogHoursForm()
return render(request, 'tracker/form.html',{'form': form})

索引用于主页上显示的模板，表单用于表单.py.

表格

class LogHoursForm(forms.Form):
day = forms.DateField()
hours = forms.DecimalField(max_digits=10, decimal_places=2)
developer = forms.ModelChoiceField(queryset=Developer.objects.all())
project = forms.ModelChoiceField(queryset=Project.objects.all())

这是URL:urlpatters=[路径(''，views.index，name='index'(，]

表单.html是

<h1> LogHours Form</h1>
<hr>
<form action="" method="post">
{% csrf_token %}
{{form}}
<input type="submit">
</form>

和index.html:

<ul>
<b>Logged hours grouped by project:</b>
{% for obj in hours_grouped_project %}
<li>
{% ifchanged obj.proj_assignment %}
<b>Project name:</b>
{{obj.proj_assignment|linebreaks}}
{% endifchanged %}
<i>Sorted Date: </i>
{{obj}}
</li>
{% endfor %}
</ul>

Answer 1

在函数index(request):中

def index(request):
if request.method=='POST':
form(request)
else:
template = loader.get_template('tracker/index.html')
hours_grouped_project = LogHours.objects.all().order_by('proj_assignment__project__name', 'day')
form = LogHoursForm()
context = {
'hours_grouped_project': hours_grouped_project,
'form': form,
}
return HttpResponse(template.render(context, request))

然后，您可以像这样从index.html呈现表单。

...
<form action="" method="post">
{% csrf_token %}
{{form}}
<input type="submit">
...
