DJANGO 模板不共享 static 文件

Question

I have a currently have a problem. I got two django templates: cart.html and index.html . In the cart.html there is a javascript file linked. Both of these files should acces the static files in the static folder. The problem now is that, when I try to acces the static files from the linked cart.html javascript file it gives me this error: [15/Aug/2022 20:14:40] "GET /cart/images/fruits/Kornknacker.jpg HTTP/1.1" 404 2419 These are my settings: STATIC_URL = 'static/'

STATICFILES_DIRS = (os.path.join(BASE_DIR, 'static'),)

Here is the project structure: Project

Here is the javascript file:

{% load static %}
function loadCart() {
    let productsSection = document.getElementById("products_section");
    productsSection.innerHTML = '';
    let productHTML = '';
    let totalPrice = 0;
    let cartItems = JSON.parse(localStorage.getItem('cart'));
    if (cartItems && cartItems.length > 0) {
        for (let item of cartItems) {
            totalPrice = totalPrice + (item.quantity * item.price);
            productHTML = productHTML + `
        <div class="product-card" data-name="${item.itemName}" data-price="${item.price}" data-id="${item.itemId}">
        <div>
            <img src="{%static '/images/fruits/${item.itemName}.jpg'%}" alt="FRUIT" width="180">
        </div>
        <h3>
        ${item.itemName}
        </h3>
        <div>
            Anzahl: ${item.quantity}
        </div>
        <div>
            Preis: ${item.quantity * item.price}€
        </div>
    </div>
        `;
        }
        document.getElementById("total_price_container").style.display = 'block';
        document.getElementById("total_price").innerHTML = totalPrice;
        document.getElementById("no-products_section").style.display = 'none';
        document.getElementById("checkout-section").style.display = 'flex';
        document.getElementById("order-process_section").style.display = 'none';
        productsSection.innerHTML = productHTML;
    }
    else {
        document.getElementById("no-products_section").style.display = 'block';
        document.getElementById("checkout-section").style.display = 'none';
        document.getElementById("total_price_container").style.display = 'none';
    }
};
loadCart();

document.getElementById('checkout_cart').addEventListener('click', function () {
    console.log(localStorage);
    localStorage.removeItem('cart');
    document.getElementById("products_section").innerHTML = '';
    document.getElementById("order-process_section").style.display = 'block';
    document.getElementById("checkout-section").style.display = 'none';

})
document.getElementById('clear_cart').addEventListener('click', function () {
    localStorage.removeItem('cart');
    loadCart();
})

Answer 1

the problem is that django can't didn't find (404) "Kornknacker.jpg" in

"static/cart/images/fruits/Kornknacker.jpg"

But you should probably point it to

"static/images/fruits/Kornknacker.jpg"

if that's the case try Im not sure if it will actually work :

<img src="{%static '/../images/fruits/${item.itemName}.jpg'%}" alt="FRUIT" width="180">
