Django only returns last row of dict in template-CodePudding

I am trying to return the values from a Dict in Django.

My views.py prints the the correct data in the terminal when doing a GET-request to my page, however, in my template I only get the last line of the dictionary.

I have tried looping the dict in my template and all sorts of combinations but I can't seem to make it work. Am I missing something? For instance, in the template below I print the entire dict. But it still only prints the last row somehow.

views.py

fruits = [
    'Apple', 'Banana', 'Orange']

for fruit in fruits:

    price_change = historical_prices['price_change'][::-1]
    low_price = 0
    for day in price_change:
        if day < -0.1:
            low_price  = 1
        else:
            break
        
    if low_price >= 0:
        ls_dict = {'fruit': fruit, 'low_price': low_price}
        print(ls_dict)

return render(request, "prices/index.html", {
    "ls_dict": ls_dict,
    })

Template

<p>{{ ls_dict }}</p>

Template output

{'fruit': 'Orange', 'low_price': 1}

Correct print which views.py produces

{'fruit': 'Apple', 'low_price': 1}
{'fruit': 'Banana', 'low_price': 3}
{'fruit': 'Orange', 'low_price': 1}

CodePudding user response：

The print() seems correct, but you are just overriding the variable over and over again, thus ls_dict will only be the set with the last iteration of the for loop.

You can test this by print(ls_dict) outside of the for-loop

Try the following:

ls_list = []
for fruit in fruits:

    price_change = historical_prices['price_change'][::-1]
    low_price = 0
    for day in price_change:
        if day < -0.1:
            low_price  = 1
        else:
            break
        
    if low_price >= 0:
        ls_dict = {'fruit': fruit, 'low_price': low_price}
        ls_list.append(ls_dict)

return render(request, "prices/index.html", {
    "ls_list": ls_list,
    })
