问题正则表达式，如何使用带有搜索表单的可选参数处理多个视图 URL
Problem regex, How to handle multiple View URL with optional parameters with Search form
几周以来我一直在尝试学习 Django，但此时我完全迷失了方向。我不太了解正则表达式，也看不出我的错误在哪里。
我构建了一个在不同 class 领域进行研究的应用程序。我使用模板和 url 创建了第一个视图 (view.index_cleint)。在学习使用正则表达式管理 URL 的过程中，我决定使用不同的查询过滤器创建另一个视图 (view.test_api)。 （我有 2 个模板链接到 2 个不同的视图，以显示每个正确的信息）。
这是带有正则表达式的 URL 文件：
from django.urls import path, re_path
from . import views
urlpatterns = [
path('search/', views.index_client, name='dashboard'),
re_path('^search/(?P<param>\w+)/$', views.index_client, name='dashboard'),
path('dash/', views.test_api, name='test_dash'),
re_path('^dash/(?P<param>\w+)/$', views.test_api, name='test_dash'),
]
前两个 url 用于我的视图 1 和处理搜索表单。
最后两个是我的第二个视图和处理搜索表单。
这是我第一次查看的代码：
def index_client(request, param='company_name'):
print("test all")
if request.method == 'GET' and 'q' in request.GET:
query = request.GET['q']
if query is None or query == '':
query = ''
else:
query = ''
list_param_query = ['company_name', 'email', 'status', 'id']
if param not in list_param_query:
param = 'company_name'
url_param = param + '/'
try:
last_update_obj = UpdateDatabase.objects.latest('last_update')
except UpdateDatabase.DoesNotExist:
diff_date = None
hours = 0
minutes = 0
seconds = 0
print("No last_update in database")
else:
last_update = last_update_obj.last_update
date_now = timezone.now()
diff_date = date_now - last_update
days, seconds = diff_date.days, diff_date.seconds
hours = days * 24 + seconds // 3600
minutes = (seconds % 3600) // 60
seconds = seconds % 60
try:
customer_list = Client.objects.filter(
Q(company_name__contains=query) | Q(email__contains=query)
| Q(status__contains=query) | Q(first_name__contains=query)
| Q(last_name__contains=query)).order_by(str(param))
print(customer_list)
except Client.DoesNotExist:
return render(request, 'maintenance/dashboard.html', locals())
print(customer_list.count())
page = request.GET.get('page', 1)
paginator = Paginator(customer_list, 1000)
try:
customers = paginator.page(page)
except PageNotAnInteger:
customers = paginator.page(1)
except EmptyPage:
customers = paginator.page(paginator.num_pages)
try:
total_confirmed = Client.objects.filter(status="CONFIRMED").count()
except Client.DoesNotExist:
total_confirmed = 0
print("Error can't count customers")
if diff_date is not None:
return render(request, 'maintenance/dashboard.html', {'customers': customers,
'total_confirmed': total_confirmed,
'diff_date': diff_date, 'hours': hours,
'minutes': minutes, 'seconds': seconds})
return render(request, 'maintenance/dashboard.html', {'customers': customers,
'total_confirmed': total_confirmed,
'diff_date': diff_date})
这里是我的第二个视图的代码：
def test_api(request, param='company_name'):
print("test2")
if request.method == 'GET' and 'q' in request.GET:
query = request.GET['q']
if query is None or query == '':
query = ''
else:
query = ''
list_param_query = ['company_name', 'email', 'status', 'id']
if param not in list_param_query:
param = 'company_name'
url_param = param + '/'
try:
last_update_obj = UpdateDatabase.objects.latest('last_update')
except UpdateDatabase.DoesNotExist:
diff_date = None
hours = 0
minutes = 0
seconds = 0
print("No last_update in database")
else:
last_update = last_update_obj.last_update
date_now = timezone.now()
diff_date = date_now - last_update
days, seconds = diff_date.days, diff_date.seconds
hours = days * 24 + seconds // 3600
minutes = (seconds % 3600) // 60
seconds = seconds % 60
try:
search_1 = Q(status__contains="CONFIRMED")
customer_list = Client.objects.filter(search_1 &
Q(company_name__contains=query) | Q(email__contains=query)
| Q(status__contains=query) | Q(first_name__contains=query)
| Q(last_name__contains=query)).order_by(str(param))
print(customer_list)
except Client.DoesNotExist:
return render(request, 'maintenance/dashboard_p1.html', locals())
print(customer_list.count())
page = request.GET.get('page', 1)
paginator = Paginator(customer_list, 1000)
try:
customers = paginator.page(page)
except PageNotAnInteger:
customers = paginator.page(1)
except EmptyPage:
customers = paginator.page(paginator.num_pages)
try:
total_confirmed = Client.objects.filter(status="CONFIRMED", priority=1).count()
except Client.DoesNotExist:
total_confirmed = 0
print("Error can't count customers")
if diff_date is not None:
return render(request, 'maintenance/dashboard_p1.html', {'customers': customers,
'total_confirmed': total_confirmed,
'diff_date': diff_date, 'hours': hours,
'minutes': minutes, 'seconds': seconds})
return render(request, 'maintenance/dashboard_p1.html', {'customers': customers,
'total_confirmed': total_confirmed,
'diff_date': diff_date})
万一这是我用于我的观点的模型：
class Client(models.Model):
company_name = models.CharField(max_length=100)
first_name = models.CharField(max_length=100)
last_name = models.CharField(max_length=100)
email = models.EmailField(max_length=70, unique=True)
is_confirmed = models.BooleanField(default=False)
is_open = models.BooleanField(default=False)
priority = models.IntegerField(default=0)
date_open = models.DateTimeField(null=True, blank=True)
date_confirmed = models.DateTimeField(null=True, blank=True)
CONFIRMED = 'CONFIRMED'
WAITING = 'WAITING'
OPEN = 'OPEN'
MNT_STATUS = [
(CONFIRMED, 'Confirmed'),
(OPEN, 'Open'),
(WAITING, 'Waiting'),
]
status = models.CharField(
max_length=11,
choices=MNT_STATUS,
default=WAITING,
)
第一个视图和第二个视图之间的唯一区别是用于获取所有优先级为 1 的客户的过滤器：
在第一个视图中：
try:
customer_list = Client.objects.filter(
Q(company_name__contains=query) | Q(email__contains=query)
| Q(status__contains=query) | Q(first_name__contains=query)
| Q(last_name__contains=query)).order_by(str(param))
print(customer_list)
except Client.DoesNotExist:
return render(request, 'maintenance/dashboard.html', locals())
在第二个视图中：
try:
search_1 = Q(status__contains="CONFIRMED")
customer_list = Client.objects.filter(search_1 &
Q(company_name__contains=query) | Q(email__contains=query)
| Q(status__contains=query) | Q(first_name__contains=query)
| Q(last_name__contains=query)).order_by(str(param))
print(customer_list)
except Client.DoesNotExist:
return render(request, 'maintenance/dashboard_p1.html', locals())
在创建我的第二个视图 test_api 并添加两个最后一个 URL 之前一切正常，当我点击我的搜索表单时，我被重定向到我的视图 1 并且搜索成功.
但是由于我每次从视图 2 的模板中进行研究时都会添加我的第二个视图，因此视图 1 查询的结果是 display.I 不仅获得优先级 1，而且获得所有对象
当我从“127.0.0.1:8000/dash/”（视图 2）进行研究时，我看到了一个 printf(2)，它在我的第二个视图中，但查询没有得到尊重，我得到视图 1 的结果。
你看到我犯了什么错误了吗？
提前Tx！
一切似乎都是对的。我认为问题出在这里 search_1 = Q(status__contains="CONFIRMED").
请向我们展示您的客户端模型。 （对不起，我不能发表评论）
