Question

所以我的detailView页面上有一个按钮，用于我的模特＆＃39;患者＆＃39;，这会带你到我的其他模特＆＃39;的createView。我想要的是预约的外键字段，这取决于我来自哪个DetailView。到目前为止，这是我的代码：

urls.py：

models.py：

# /patients/appointment/add
url(r'appointment/add/$', views.appointmentCreate.as_view(), name='appointment-create'),

views.py：

class patient(models.Model):
    TITLE_CHOICES = (
        ('Mr', 'Mr'),
        ('Mrs', 'Mrs'),
        ('Ms', 'Ms'),
        ('Miss', 'Miss'),
    )

    Title = models.CharField(max_length=100, blank=True, choices=TITLE_CHOICES)
    First_Name = models.CharField(max_length=250, default='')
    Surname = models.CharField(max_length=250, default='')
    DOB = models.DateField()

class appointment(models.Model):
    Patient = models.ForeignKey(patient, on_delete=models.CASCADE)

形状template.html：

class appointmentCreate(LoginRequiredMixin, CreateView):
    model = appointment
    fields = ['Patient', 'Date', 'Time', 'Duration', 'Location', 'Clinician', 'AppointmentType']

appointment_form.html：

<body>

{% for field in form %}
    <div class="form-group">
        <div class="col-sm-offset-2 col-sm-10">
            <span class="text-danger small">{{ field.errors }}</span>
        </div>
        <label class="control-label col-sm-2">{{ field.label_tag }}</label>
        <div class="col-sm-10">{{ field }}</div>
    </div>
{% endfor %}
</body>

来自患者detailView的按钮创建约会：

<div class="container-fluid">

    <div class="row">
        <div class="col-lg-12">
            <div class="panel panel-default">
                <div class="panel-body">
                    <h3>Add new appointment</h3>
                    <form class="form-horizontal" action="" method="post" enctype="multipart/form-data">
                        {% csrf_token %}
                        {% include 'patients/form-template.html' %}
                        <div class="form-group">
                            <div class="col-sm-offset-2 col-sm-10">
                                <button type="submit" class="btn btn-success">Submit</button>
                            </div>
                        </div>
                    </form>

                </div>

            </div>

        </div>

    </div>

</div>

例如，网址可能是/ appname / appointment / add /？Patient = pk，其中结尾部分确定患者的价值。我已经研究了get_initial函数，但不明白它是如何帮助我实现这一目标的。任何帮助表示赞赏。我对django比较新，所以请不要太复杂。

编辑：我已将此代码添加到我的模型中，感谢Dimitris Kougioumtzis：

<ul class="nav nav-pills" style="margin-bottom: 10px;">
    <li role="presentation" class="active"><a href="{% url 'patients:index' %}">View All</a></li>
    <li role="presentation"><a href="{% url 'patients:appointment-create' %}">Add New Appointment</a></li>
</ul>

我如何实现此代码？

Answer 1

首先创建一个modelForm：

from django import forms
from your_app.models import appointment

class AppointmentForm(forms.ModelForm):
 class Meta:
    model = appointment
    fields = ['Patient', 'Date', 'Time', 'Duration', 'Location',   'Clinician', 'AppointmentType']

然后在CreateView中传递模型表单：

 class appointmentCreate(LoginRequiredMixin, CreateView):
    model = appointment
    form_class = AppointmentForm

    def get_initial(self):
      patient = self.request.GET.get('patient')
      return {
        'patient': patient,
      }

将根据请求获取参数

填充您的患者选择字段

Django从URL预填充表单中的数据
