How to pass selection from Django template to Class view-CodePudding

I am struggling with something that should be routine for me by now but I have a mental block. I have a model that stores Country names and a slug version of the name.

Eg. "United States", "united-states"

I want to display the country names in a template for selection, then return the selected country's slug value to the Class based View which will then obtain the data. The list of countries can be links or dropdown - whatever. But I need to obtain the selected value in the View. Here is a simplified version:

Template

{% extends 'base.html' %}
{% block content %}
<form method="POST">
    {% for country in object_list %}
        <a href="{{country.slug_name}}">{{ country.pretty_name }}</a></br>
    {% endfor %}
</form>
{% endblock content %}

View

class CountryView(TemplateView):
    country_name = THE SLUG
    country_obj = Country(country_name)
    country_obj.build_country_dictionary()
    country_obj.display()

So I think I need one of the get methods to access this but I cannot work it out. Thanks for any help.

The "structured way"

Have a look at FormView, where you define your form class (which you also need to create, depends on your situation can be a model form as well). The rest is pretty much handled by the view.

PSEUDO code

class MyForm(ModelForm):
    model = YourModel

class MyFormView(FormView):
    form_class = MyForm

    # depends on what you want to do, you can overwrite form_valid to do your logic

The quickest way

PSEUDO code

{% extends 'base.html' %}
{% block content %}
<form method="POST">
    {% csrf_token %}
    <select name="selection">
    {% for country in object_list %}
        <option value="{{ country.slug_name }}">{{ country.pretty_name }}</option>
    {% endfor %}
    </select>
    <input type="submit">Submit</input>
</form>
{% endblock content %}

class CountryView(TemplateView):
    def post(self, request, *args, **kwargs):
        selection = request.POST.get('selection')
