Python Django表单字段不显示

我想在视图中显示简单的搜索表单

forms.py:

from django import forms
from django.utils.translation import gettext_lazy as _

class Vehicle_Search_by_VIN(forms.Form):
    vin = models.CharField(max_length=17)
    first_registration_date = models.DateField()

class Vehicle_Search_by_Plate(forms.Form):
    plate = models.CharField(max_length=7)
    last_four_diggits_of_vin = models.DateField(max_length=4)

from django.shortcuts import render
from django.views import View
from .forms import *


class VehicleSearch(View):
    template = 'vehicle_search_template.html'
    cxt = {
        'Search_by_VIN': Vehicle_Search_by_VIN(),
        'Search_by_Plate': Vehicle_Search_by_Plate()
    }
    def get(self, request):
        return render(request, self.template, self.cxt)

<form class="by_vin" method="POST" action="">
        {% csrf_token %}
        {{ Search_by_VIN.as_p }}
    
        <button name='action' value='login' type="submit">Suchen</button>
</form>
    
    <form class="by_plate" method="POST" action="">
        {% csrf_token %}
        {{ Search_by_Plate.as_p }}
    
        <button name='action' value='signup' type="submit">Suchen</button>
    </form>

视图。py:

from django import forms
from django.utils.translation import gettext_lazy as _

class Vehicle_Search_by_VIN(forms.Form):
    vin = models.CharField(max_length=17)
    first_registration_date = models.DateField()

class Vehicle_Search_by_Plate(forms.Form):
    plate = models.CharField(max_length=7)
    last_four_diggits_of_vin = models.DateField(max_length=4)

from django.shortcuts import render
from django.views import View
from .forms import *


class VehicleSearch(View):
    template = 'vehicle_search_template.html'
    cxt = {
        'Search_by_VIN': Vehicle_Search_by_VIN(),
        'Search_by_Plate': Vehicle_Search_by_Plate()
    }
    def get(self, request):
        return render(request, self.template, self.cxt)

<form class="by_vin" method="POST" action="">
        {% csrf_token %}
        {{ Search_by_VIN.as_p }}
    
        <button name='action' value='login' type="submit">Suchen</button>
</form>
    
    <form class="by_plate" method="POST" action="">
        {% csrf_token %}
        {{ Search_by_Plate.as_p }}
    
        <button name='action' value='signup' type="submit">Suchen</button>
    </form>

我的模板文件：

from django import forms
from django.utils.translation import gettext_lazy as _

class Vehicle_Search_by_VIN(forms.Form):
    vin = models.CharField(max_length=17)
    first_registration_date = models.DateField()

class Vehicle_Search_by_Plate(forms.Form):
    plate = models.CharField(max_length=7)
    last_four_diggits_of_vin = models.DateField(max_length=4)

from django.shortcuts import render
from django.views import View
from .forms import *


class VehicleSearch(View):
    template = 'vehicle_search_template.html'
    cxt = {
        'Search_by_VIN': Vehicle_Search_by_VIN(),
        'Search_by_Plate': Vehicle_Search_by_Plate()
    }
    def get(self, request):
        return render(request, self.template, self.cxt)

<form class="by_vin" method="POST" action="">
        {% csrf_token %}
        {{ Search_by_VIN.as_p }}
    
        <button name='action' value='login' type="submit">Suchen</button>
</form>
    
    <form class="by_plate" method="POST" action="">
        {% csrf_token %}
        {{ Search_by_Plate.as_p }}
    
        <button name='action' value='signup' type="submit">Suchen</button>
    </form>

{%csrf_令牌%}
{{Search_by_VIN.as_p}

{%csrf_令牌%}
{{Search_by_Plate.as_p}

但因此，视图中仅显示提交按钮。有人知道为什么没有呈现我的表单吗？

在

视图.py

中，我想您在

get（）

函数中缺少了

*args

和

**kwargs

参数

class VehicleSearch(View):

    template = 'vehicle_search_template.html'

    cxt = {
        'Search_by_VIN': Vehicle_Search_by_VIN(),
        'Search_by_Plate': Vehicle_Search_by_Plate()
    }

    def get(self, request, *args, **kwargs):  # HERE
        return render(request, self.template, self.cxt)

默认情况下，基于类的视图只支持每个视图的单个表单，但根据您的逻辑，您可以使用很少的选项来克服此限制。在

views.py

中参考此线程，我认为您在

get（）

函数中缺少

和

**kwargs

class VehicleSearch(View):

    template = 'vehicle_search_template.html'

    cxt = {
        'Search_by_VIN': Vehicle_Search_by_VIN(),
        'Search_by_Plate': Vehicle_Search_by_Plate()
    }

尝试在模板变量中提供完整路径，例如，如果你的应用程序名为my_app，则

模板='my app/vehicle_search_template.html'
