传递值列表来Django的视图通过jQuery Ajax调用 [英] Passing list of values to django view via jQuery ajax call

问题描述

我想从一个网页传递数值（IDS）的列表，以另一种使用jQuery AJAX调用。我无法弄清楚如何传递和阅读列表中的所有值。我可以成功发布和读取1值，但不能多值。这是我到目前为止有：

I'm trying to pass a list of numeric values (ids) from one web page to another with jQuery ajax call. I can't figure out how to pass and read all the values in the list. I can successfully post and read 1 value but not multiple values. Here is what I have so far:

jQuery的：

var postUrl = "http://localhost:8000/ingredients/";
$('li').click(function(){
    values = [1, 2];
    $.ajax({
        url: postUrl,
        type: 'POST',
        data: {'terid': values},
        traditional: true,
        dataType: 'html',
        success: function(result){
            $('#ingredients').append(result);
            }
    });       
});

/成分/视图：

def ingredients(request):
    if request.is_ajax():
        ourid = request.POST.get('terid', False)
        ingredients = Ingredience.objects.filter(food__id__in=ourid)
        t = get_template('ingredients.html')
        html = t.render(Context({'ingredients': ingredients,}))
        return HttpResponse(html)
    else:
        html = '<p>This is not ajax</p>'      
        return HttpResponse(html)

使用萤火虫，我可以看到那个帖子包含的ID，很可能在错误的格式（terid = 1＆安培; terid = 2）。所以我的看法的成分只摄取terid = 2。我究竟做错了什么？

With Firebug I can see that POST contains both ids but probably in the wrong format (terid=1&terid=2). So my ingredients view picks up only terid=2. What am I doing wrong?

编辑： 为了澄清，我需要的ourid变量传递值[1，2]，在配料视图中的过滤器。

To clarify, I need the ourid variable pass values [1, 2] to the filter in the ingredients view.

推荐答案

我找到了一个解决方案，我原来的问题。在这里发布一个答案，希望这可以帮助别人。

I found a solution to my original problem. Posting it here as an answer, hopefully it helps somebody.

jQuery的：

var postUrl = "http://localhost:8000/ingredients/";
$('li').click(function(){
    values = [1, 2];
    var jsonText = JSON.stringify(values);
    $.ajax({
        url: postUrl,
        type: 'POST',
        data: jsonText,
        traditional: true,
        dataType: 'html',
        success: function(result){
            $('#ingredients').append(result);
            }
    });       
});

/成分/视图：

def ingredients(request):
    if request.is_ajax():
        ourid = json.loads(request.raw_post_data)
        ingredients = Ingredience.objects.filter(food__id__in=ourid)
        t = get_template('ingredients.html')
        html = t.render(Context({'ingredients': ingredients,}))
        return HttpResponse(html)
    else:
        html = '<p>This is not ajax</p>'      
        return HttpResponse(html)
