How to add Icons in Django forms creating forms from Models

Question

i am newbie in python, i'm try to create forms from models in django. I need to put icons in the html5 lines

i'm using fontawesome and i can put icon if i add the html codeline but i need to bring the variable "fa fa-shower" or "{icon name}" from my forms.py

my code in forms.py is:

class LoginForm(forms.ModelForm):
    class Meta:
        model = User    
        fields = ['username', 'password']
        icons = {
            'username': 'fa fa-user',
            'password': 'fa fa-lock',
        }        
        labels = {
            'username': 'User/Correo:  ',
            'password': 'Contraseña  ',
        }    
        widgets = {
            'username': forms.TextInput(attrs={'class': 'form-control'}),
            'email': forms.TextInput(attrs={'class': 'form-control'}), 
            'password': forms.PasswordInput(attrs={'class': 'form-control'}), 
        }

class iconModelForm(LoginForm):
    def __init__(self, *args, **kwargs):
        super().__init__(self, *args, **kwargs)
        icons = getattr(self.Meta, 'icons', dict())
        
        for field_name, field in self.fields.items():
            if field_name in icons:
                field.icon = icons[field_name]

how can pass the context of two classes from view to html?

my views.py is:

class LoginLocal(View):
    def get(self, request):
                            
        contexto = {
            'formLogin': LoginForm(),
            # 'formIcon': iconModelForm(),
            }
        print(contexto)
        return render(request, 'login_reg_app/login.html', contexto)

and how can i read two list in the same for in html? I tried to use ZIP but it showed error.

my file login.html is:

<form action="{% url 'login_reg_app:login' %}" method="post" >
                {% csrf_token %}
                {{ formLogin.non_field_errors }}   

                {% for field in formLogin %}
      
                <div class="mt-3 row">


                    <label for="{{ field.id_for_label }}" class="col-sm-3 col-form-label"><i class="{{ field.icon }}"></i>{{ field.label }}</label>
                    <div class="col-sm-9">
                        {{ field }}
                    </div>

                    {% if field.errors %}

                    <div class="alert alert-danger mt-2" role="alert">
                        {% for error in field.errors %}
                        {{ error }}
                        {% endfor %}
                    </div>

                    {% endif %}

i want to know, how can i read the second context in <i class="{{ field.icon }}"></i> using my class iconModelForm?
