如何在不使用django-forms的情况下在html表单字段中设置名称值和选择字段值？

Question

假设我想在html选择标记中给用户2选项。

我想要帮助，在Python中实现完整的MVC。我不想使用django表单。示例html代码：

<form method="POST">
                        <div class="form-row">
                            <div class="name">Name</div>
                            <div class="value">
                                <div class="input-group">
                                    <input class="input--style-5" type="text" name="name" required>
                                </div>
                            </div>
                        </div>
                        <div class="form-row">
                                <div class="name">Applying In</div>
                                <div class="value">
                                    <div class="input-group">
                                        <div class="rs-select2 js-select-simple select--no-search">
                                            <select name="subject" required>
                                                <option disabled="disabled" selected="selected"> Applying Department</option>
                                                <option>Backend</option>
                                                <option>Mobile</option>
                                                
                                            </select>
                                            <div class="select-dropdown"></div>
                                        </div>
                                    </div>
                                </div>
                            </div>

Answer 1

在将在表单提交时调用的option = request.GET['subject']中使用view.py。您将只获得一个选项，因为您正在选择模板中的单个选项。

Answer 2

假设我们有这样一个模型：

from django.db import models
from django import forms

class Foo(models.Model):
    CHOICES= (
        ('choice_one', 'choice one'),
        ('choice_two', 'choice two'),
    )
    user_choices= models.CharField(max_length=10, choices=CHOICES)        



class FooForm(forms.ModelForm):
    class Meta:
        model = Foo
        fields = ['user_choices']

视图：

from django.shortcuts import redirect, render
from . import models

def user_choices(request):
    url = request.META.get('HTTP_REFERER')  # get last url
    if request.method == 'POST':
        form = models.FooForm(request.POST)
        if form.is_valid():
            data = models.Foo()
            data.user_choices= request.GET.get('user_choices')
            data.save()
            return redirect(url)
    return render(request, 'user_choices.html', context)

然后在模板中：

<form action="{% url 'app_name:user_choices' %}" method="POST"> # url to above function
    <select name ='user_choices'>
        <option name="user_choices" value="choice_one">choice one</option>
        <option name="user_choices" value="choice_two">choice two</option>
    </select>
    <button type="submit">submit</button>
</form>
