Django 表格不显示

Question

我正在做一些项目并最终遇到了一些问题。 所以我的表单根本不会在我的模板中显示出来。 但我之前创建了另一种形式，它应该可以正常工作！

所以我的代码：

模型.py

class Project(models.Model):
    class Meta:
        db_table = "project"

    COLORS = (
        ('R', 'Red'),
        ('B', 'Blue'),
        ('G', 'Green'),
        ('Y', 'Yellow')
     )
    project_title = models.CharField(max_length=200)
    project_color = models.CharField(max_length=1, choices=COLORS)

    def __str__(self):
        return self.project_title

forms.py

class ProjectForm(ModelForm):
    class Meta:
        model = Project
        fields = ['project_title', 'project_color']

视图.py

def addproject(request):
    if request.POST:
        form_p = ProjectForm(request.POST)
        if form_p.is_valid():
            form_p.save(commit=False)
            return HttpResponseRedirect('/')
   else:
        form_p = ProjectForm()
    context = {
        'projects': Project.objects.all(),
        "form": form_p,
        'username': auth.get_user(request).username,
    }
    context.update(csrf(request))
    return render(request, 'index.html', context)

网址.py

urlpatterns = [
    url(r'^addproject/$', views.addproject, name='addproject'),]

索引.html

<form action="/addproject/" method="post">
    {% csrf_token %}
    {{ form_p.as_table }}
    <button type="submit" class="btn btn-primary">Add Project</button>
</form>

Answer 1

问题出在模板内，您将上下文变量称为form_p，同时将其传递为“ form” ：

index.html

<form action="/addproject/" method="post">
    {% csrf_token %}
    {{ form.as_table }}
    <button type="submit" class="btn btn-primary">Add Project</button>
</form>

Answer 2

您是否已将表单导入到views.py中？ 将此放入您的views.py

from .forms import ProjectForm

Answer 3

确保您使用的是“ModelForm”而不是“Form”

class NewAccountForm(forms.ModelForm):
    class Meta:
        model = NewAccount
        fields = ('name',)
