Question

我想做的是从模型中获取数据以显示引导程序模态。我现在正在做的是尝试将函数数据传递到视图中，并通过视图尝试在模式中显示with。我遇到的问题是：

第47行的块标记无效：“ show_profile”，应为“空”或“ endfor”。您忘记注册或加载此标签了吗？

当我试图传递数据时我做错什么了吗，还是我的标签或其他东西出了问题？

Answer 1

更改此行

var color_prices = new Array();
color_prices["Orange"]=1;
color_prices["Blue"]=2;
color_prices["Green"]=3;

function getColorDetails()
{
    //here we rename the variable and convert from integer to object
    var colorDetails = {
                         price: 0,
                         name: undefined
                        };

    var theForm = document.forms["order-form"];

    var selectedColor = theForm.elements["COLOR"];

    for(var i = 0; i < selectedColor.length; i++)
    {
        if(selectedColor[i].checked)
        {
            //here we store the color price inside colorDetails
            colorDetails.price = color_prices[selectedColor[i].value];
            //and we add this new line where we save the name of the color
            colorDetails.name = selectedColor[i].value;
            break;
        }
    }
    return colorDetails;
}

var colorDetails = getColorDetails();

document.getElementById('colorPrice').innerHTML = colorDetails.name + ": " + colorDetails.price.toFixed(2);

到

{% show_profile %}

和您的方法

{% for i in show_profile %}
    {{ i.full_name }}
{% endfor %}

到

def showprofile(full_name):
       return mentee.objects.values().filter(full_name="Katha Benterman")

Answer 2

{％show_profile％}将调用需要注册的模板标签，因此会出现错误。您要显示{{show_profile.full_name}}。

此外，您应该更改模型方法：

def showprofile(self, full_name):
    return self.objects.filter(full_name=fullname)

假设您不只是想在当前过滤器中放一个非常具体的名称。
