How to get array of values from checkbox form Django

Question

I have HTML form like this:

    <p>Models Sizes IDs:</p>
    <input type="checkbox" name="model_size_ids[]" value="1">XS</input>
    <input type="checkbox" name="model_size_ids[]" value="2">S</input>
    <input type="checkbox" name="model_size_ids[]" value="3">M</input>
    <input type="checkbox" name="model_size_ids[]" value="4">L</input>
    <button>Submit</button>

I'm trying to receive an array of checked values on server side in my View:

size_ids = request.data['model_size_ids[]']

But, I can extract only one and the last value. So if I check 2-3 values in checkbox form, I receive only last value in my view. I also tried to name input field without bra?kets and the result was the same. Can anybody tell me, how can I solve that? Thanks!

使用 getlist 方法获取所选选项的列表

request.POST.getlist('model_size_ids[]')
