24.1 Adding address

To enable the functionality of adding an address to a specific client, we need to first update the add_address.html file.

add_address.html

{% extends 'base.html' %}
{% load static %}

{% block body %}

<h3>
    Add Address
</h3>
<a href="{% url 'checkout' %}">Return to checkout</a>

<h3>Add a new address</h3>
<form method="POST" action="{% url 'add_address' %}">
    {% csrf_token %}
    <!--Adding the inputs based on the attributes of the Address class-->
    <input type="text" name="street" placeholder="Street">
    <input type="number" name="number" placeholder="Number">
    <input type="text" name="apartment" placeholder="Apartment">
    <input type="number" name="zip_code" placeholder="Zip Code">
    <input type="text" name="city" placeholder="City">
    <input type="text" name="state" placeholder="State">
    <button type="submit">Add address</button>
</form>


{% endblock %}

In the updated add_address.html file, we incorporated the following elements:

• An <a> tag to allow the client to return to the checkout page.

• Input fields for the client to enter values corresponding to the attributes defined in the Address class.

Subsequently, we need to update the add_address function in our views.py file to enable the creation of an Address instance associated with the client using the provided input values.

views.py

def add_address(request) :
    if request.method == "POST" : #? handling the submission of the form
        if request.user.is_authenticated:
            client = request.user.client
        else :
            if request.COOKIES.get('id_session') :
                id_session = request.COOKIES.get("id_session")
                client, created = Client.objects.get_or_create(id_session=id_session)
            else : #? if the client enters directly on the cart, whithout generating cookies
                return redirect('store') #? return directly to the store as the cart should be empty
        data = request.POST.dict() #? converts the request data to a dictionary
        address = Adres.objects.create(client=client, street=data.get('street'), city=data.get('city'), state=data.get('state'), zip_code=data.get('zip_code'), number=int(data.get('number')), apartment=data.get('apartment'))
        address.save()
        return redirect('checkout') #? redirects the user to the checkout page to add more addresses if needed
    else :
        context = {}
        return render(request, 'add_address.html', context)

The process implemented in the code above is analogous to the steps undertaken in previous sections:

• Verify if the user is authenticated.

• If the user is not authenticated, retrieve the id_session generated by cookies.

• Extract the input data from the HTML form in dictionary format.

• Utilize the extracted data to create and save a new Address instance.

• Redirect the user back to the checkout page, allowing for the addition of more addresses if needed.

The add_address function supports both authenticated and unauthenticated clients.
