如何在django布尔字段中使用切换开关? [英] How to use toggle switch with django boolean field?

问题描述

我有一个work_experience模型，其中包含"is_working"字段，当用户仍在公司工作时，该字段为true.在前端，我正在使用拨动开关，并且要在单击时更改布尔字段值"is_working".在django中使用toggle的逻辑应该是什么?

I have a work_experience model which contains "is_working" field which is true when a user is still working at a company. On front end I'm using a toggle switch and I want to change the boolean field value "is_working" on click. What should be the logic to use toggle in django?

拨动开关

HTML

<div style="display:inline-block">
    <label>Currently working here?</label>
    <label class="switch">
        <input type="checkbox">
        <span class="slider round"></span>
    </label>
</div>

模型

class Work_Experience(models.Model):
    job_title       = models.CharField(max_length=100, null=True, blank=True)
    company         = models.CharField(max_length=100, null=True, blank=True)
    description     = models.CharField(max_length=300, null=True, blank=True)
    exp_start_date  = models.DateField(null=True, blank=True)
    exp_end_date    = models.DateField(null=True, blank=True)
    is_working      = models.BooleanField(default=False)

推荐答案

为 CharField 提供 null = True 参数是一个不好的主意.

It is a bad idea to give null=True parameter for CharField.

如果要在单击时更改布尔字段值 is_working ，则需要使用 Jquery .

If you want to change the boolean field value is_working on click, you need to use Jquery.

我创建了一个名为 toggle 的应用程序，因此您需要将其替换为应用程序的名称.

I created an app named toggle, so you need to replace it with your app's name.

这是完整的代码

urls.py ::

from django.urls import path
from toggle.views import home, toggle

urlpatterns = [
    path('', home),
    path('toggle/', toggle),
]

views.py:

from django.shortcuts import render
def home(request):
    w, created = Work_Experience.objects.get_or_create(id=1)
    return render(request,'home.html', {'workexperiance': w})

from django.http import HttpResponse
from toggle.models import Work_Experience
def toggle(request):
    w = Work_Experience.objects.get(id=request.POST['id'])
    w.is_working = request.POST['isworking'] == 'true'
    w.save()
    return HttpResponse('success')

home.html:

<div style="display:inline-block">
    <label>Currently working here?</label>
    <label class="switch">
        <input type="checkbox" id="checkbox" value="{{workexperiance.is_working}}">
        <span class="slider round"></span>
    </label>
</div>
<script src="https://code.jquery.com/jquery-3.3.1.js"></script> <!-- Import Jquery Here-->
<script type="text/javascript">
$(document).ready(function() {
    $('#checkbox').change(function() {
        $.post("/toggle/", {
            id: '{{workexperiance.id}}', 
            isworking: this.checked, 
            csrfmiddlewaretoken: '{{ csrf_token }}' 
        });
    });
}); 
</script>

运行: ./manage.py runserver 并访问: http://localhost:8000

当您点击当前在这里工作吗复选框时，会立即更改布尔值"is_working".

when you click the Currently working here? check box, will instantly change the boolean field value "is_working".
