Django：使用GET将额外变量传递给LoginView？

我需要将2个变量传递到我的LoginView，我使用的是Django 3.0

我有一个模板，有两个按钮，一个用于客户，一个用于卖家。根据单击的内容，我需要在

GET

调用中发送

typeofuser

这是发送GET中变量的模板：

{% block content %}
  <h2>Ingresar con tu cuenta</h2>
  <p class="lead">Selecciona qué tipo de usuario eres</p>
  <a href="{% url 'core:login' %}?typeofuser=cliente" class="btn btn-primary btn-lg" role="button">Soy un cliente</a>
  <a href="{% url 'core:login' %}?typeofuser=vendedor" class="btn btn-secondary btn-lg" role="button">Soy un vendedor</a>
{% endblock %}

我还尝试了这一行来获取上下文：

context = super(LoginView, self).get_context_data(**kwargs)

context = super(LoginView).get_context_data(**kwargs)

但我得到了：

TypeError: 'NoneType' object is not callable 

使用此选项获取上下文：

context = super(LoginView, self).get_context_data(**kwargs)

context = super(LoginView).get_context_data(**kwargs)

返回

'super' object has no attribute 'get_context_data'

视图类中未提供任何

表单类
属性，因此出现错误

class LoginView(SuccessURLAllowedHostsMixin, FormView):
    form_class = MyLoginForm
    # other code snippets
class LoginView（SuccessURLAllowedHostsMixin，FormView）：
form_class=MyLoginForm
#其他代码段
错误
'super'对象没有“get\u context\u data”属性
rased，因为您以错误的方式调用了
super（）
方法。但是错误
TypeError:“NoneType”对象不可调用
很奇怪，你能添加错误回溯吗？@ArakkalAbu，请参见更新1。我添加了一个答案，请看一看
