我是新的Django和我有麻烦实现编辑模板到我的项目。我遇到以下错误:
没有找到带有关键字参数'{'client_id': 3}'的'all_clients'。['clients/all_clients/$']
我在网站上查看了类似的事件，例如使用关键字参数
反转'plan_edit'但我还没能指出这个问题。我认为，当我添加一个超链接到我的all_clients.html时，问题就出现了模板。此外，/clients/edit_client/?/将加载，但是在使用save changes按钮提交后，当它试图加载clients/all_clients时，NoReserse Match错误重新出现。页面。
见下面代码:
models.py
from django.db import models
# Create your models here.
class Client(models.Model):
#A client is composed of the company general info
text = models.CharField('Company Name',default = 'Company Name', max_length = 200)
phone_num = models.CharField('Phone Number', default = '000-000-000', max_length = 12)
ceo_name = models.CharField ('CEO', max_length = 50)
num_employees = models.IntegerField('Number of Employees', default = 0)
maintenance_schedule = models.CharField('maintenance schedule', max_length = 100)
date_added = models.DateTimeField(auto_now_add=True)
def __str__(self):
"""Return a string representation of the model."""
return self.text
urls . py
"""Defines URL patterns for clients."""

我认为你应该尝试的第一件事是修改URL到add_clients页面，除了你传递的id是相同的all_clients，和"django可能会混淆";
#Page for listing all clients
path('all_clients/', views.all_clients, name = 'all_clients'),
#Page for adding a new client
path('add_clients/<int:client_id>/', views.add_client, name = 'add_client'),
代替:
#Page for listing all clients
path('all_clients/', views.all_clients, name = 'all_clients'),
#Page for adding a new client
path('all_clients/<int:client_id>/', views.add_client, name = 'add_client'),
