如何在搜索栏中按布尔字段进行过滤 - django

Question

我正在开发一个 Django 项目，它是一个项目管理系统。基本上在导航栏中，我实现了一个搜索器来搜索特定项目，如标题、客户、描述等。

我想给他们搜索紧急项目的可能性（在我的项目模型中紧急是一个布尔字段），但我实现它的方式不起作用。

这是我的项目模型：

class Project(models.Model):
    title = models.CharField(max_length=255)
    description = models.CharField(max_length=1000)
    client = models.ForeignKey(Cliente, on_delete=models.CASCADE)
    complete = models.BooleanField(default=False)
    urgent = models.BooleanField(default=False)
    deadline = models.DateField()
    ...

制作搜索栏（在我的 html 文件中是:)

<form method="get" class="form-inline">
  <input class="form-control mr-sm-2" name="q" id="id_q" type="text" placeholder="Search..." aria-label="Search" value="{{query}}">

  <button class="btn btn-outline-dark my-2 my-sm-0" type="submit">
      <svg width="1em" height="1em" viewBox="0 0 16 16" class="bi bi-search" fill="currentColor"
           xmlns="http://www.w3.org/2000/svg">
          <path fill-rule="evenodd"
                d="M10.442 10.442a1 1 0 0 1 1.415 0l3.85 3.85a1 1 0 0 1-1.414 1.415l-3.85-3.85a1 1 0 0 1 0-1.415z"/>
          <path fill-rule="evenodd"
                d="M6.5 12a5.5 5.5 0 1 0 0-11 5.5 5.5 0 0 0 0 11zM13 6.5a6.5 6.5 0 1 1-13 0 6.5 6.5 0 0 1 13 0z"/>
      </svg>
  </button>
</form>

我是如何实现这个功能的：

def get_projects_qs(proj, query=None):
    queryset = []
    queries = query.split(" ")

    for q in queries:

        projects = proj.filter( Q(title__icontains=q) | Q(description__icontains=q) | Q(urgent__icontains=q) | Q(client__client__icontains=q) ).distinct()

        for project in projects:
            queryset.append(project)

    return list(set(queryset))

现在，如果我执行 Q(urgent_icontains=q) 它不起作用，但是如果我执行 Q(urgent=q) 它只在第一次工作然后我得到这个错误：

ValidationError at /marketing/
['“” value must be either True or False.']

假设我们有这样一个模型：

class Project(models.Model):
    title = models.CharField(max_length=255)
    complete = models.BooleanField(default=False)
    urgent = models.BooleanField(default=False)
    .
    .
    .

views.py:

from . models import Product


def is_valid_queryparam(param):
    return param != '' and param is not None


def search(request):
    queryset = Product.objects.all()

    search = request.GET.get('search')
    complete = request.GET.get('complete')
    urgent = request.GET.get('urgent')


    if is_valid_queryparam(search):
        queryset = queryset.filter(title__icontains=search)

    if is_valid_queryparam(complete):
        queryset = queryset.filter(complete=True)

    elif is_valid_queryparam(urgent):
        queryset = queryset.filter(urgent=True)

    context = {
        'queryset': queryset
    }

    return render(request, 'search.html', context)

现在在模板中（search.html）：

<form id="mySearch" method="GET">
    <input type="search" name="search" placeholder="Search..." />
    <button" type="submit">Click to Search</button>

    <input type="checkbox" name="complete" id="checkbox-1" onchange="$('#mySearch').submit();" {% if request.GET.complete == 'on' %} checked {% endif %}>
    <label for="checkbox-1">complete</label>

    <input type="checkbox" name="urgent" id="checkbox-2" onchange="$('#mySearch').submit();" {% if request.GET.urgent == 'on' %} checked {% endif %}>
    <label for="checkbox-2">urgent</label>
</form>
