我正在Django制作一个完整的管理员和发票应用程序。
对于发票应用,用户点击"创建销售发票"出现发票屏幕。
现在我希望系统在出现此屏幕时动态生成新帐单,但不会保存。当用户开始输入物品时,我想要一个新的物品细节(即每个物品有一个物品细节,其中包含物品清单,数量和价格)。
但是,除非用户点击创建帐单按钮,否则不会保存任何内容。
我需要有关如何做这件事的帮助,即在用户转到创建账单时创建账单和项目详细信息,用外键链接这两个,但如果用户没有结束,还可以选择丢弃它们点击"保存"按钮。

我的相关jquery文件(只是必要部分):
生成表:
function generateTableRow() {
var emptyColumn = document.createElement('tr');
emptyColumn.innerHTML = '<td><a class="cut">-</a><span class="itemcode" contenteditable></span></td>' +
'<td colspan="2"><span contenteditable></span></td>' +
'<td><span contenteditable>100.00</span></td>' +
'<td><span contenteditable></span></td>' +
'<td><span contenteditable></span></td>'+
'<td><span contenteditable></span></td>' +
'<td><span contenteditable></span></td>'+
'<td><span contenteditable></span></td>' +
'<td><span contenteditable></span></td>' +
'<td><span contenteditable></span></td>' ;
return emptyColumn;
}
在用户输入客户代码时添加客户详细信息:
$( "#customer-code" ).change(function() {
/*alert( "Handler for .change() called." );*/
var input = $("#customer-code").val();
(function() {
$.ajax({
url : "",
type : "POST",
data : { customer_code: input,
datatype: 'customer',
'csrfmiddlewaretoken': csrf_token}, // data sent with the post request
dataType: 'json',
// handle a successful response
success : function(jsondata) {
$('#companyname').html(jsondata['name'])
$('#companyaddress').html(jsondata['address'])
console.log(jsondata); // log the returned json to the console
console.log("success"); // another sanity check
},
});
}());
});
同样,对于产品,在用户输入产品ID时,会自动生成其他详细信息:
$("#inventory_table").on("focus", ".itemcode", function(){
$(this).data("initialText", $(this).html());
/*alert( "On focus for table inventory called." );*/
});
$("#inventory_table").on("blur", ".itemcode", function(){
/*alert( "On blur for table inventory called." );*/
var input = $(this).html();
if ($(this).data("initialText") !== $(this).html()) {
var el = this;
/*valueis='Hi 5'
alert($(this).closest('tr').find('td:nth-child(4) span').html());*/
(function() {
$.ajax({
url : "",
type : "POST",
data : { item_code: input,
datatype: 'item',
'csrfmiddlewaretoken': csrf_token}, // data sent with the post request
dataType: 'json',
// handle a successful response
success : function(jsondata) {
$(el).closest('tr').find('td:nth-child(2) span').html(jsondata['name'])
$(el).closest('tr').find('td:nth-child(2) span').html(jsondata['name'])
$(el).closest('tr').find('td:nth-child(3) span').html(jsondata['sellingprice'])
console.log(jsondata); // log the returned json to the console
alert(jsondata['name']);
console.log("success"); // another sanity check
},
});
}());
}
});
最后,这是我的views.py文件的相关功能:
def bill(request):
if request.method == 'POST':
datatype = request.POST.get('datatype')
if (datatype == 'customer'):
customerkey = request.POST.get('customer_code')
response_data = {}
response_data['name'] = Customer.object.get(customer_key__iexact=customerkey).name
response_data['address'] = Customer.object.get(customer_key__iexact=customerkey).address
jsondata = json.dumps(response_data)
return HttpResponse(jsondata)
if (datatype == 'item'):
productkey = request.POST.get('item_code')
response_data = {}
response_data['name'] = Product.object.get(prodkey__iexact=productkey).name
response_data['sellingprice'] = float(Product.object.get(prodkey__iexact=productkey).selling_price)
#response_data['address'] = Product.object.get(prodkey__iexact=productkey).address
jsondata = json.dumps(response_data)
return HttpResponse(jsondata)
return render(request, 'bill/invoicing.html')
答案 0 :(得分:0)
您应该使用Model Forms向用户输出表单,以便在提交后填充并创建对象。如果需要在表单中预先填写一些信息,也可以使用一些上下文数据。
另一种方法是创建一个对象并将其标记为&#34; CANCELED&#34;如果你想记住一些用户的尝试(有时可能有用)或者只是将其删除(如果非常常情况,那么可能会导致性能问题,以免填写开始账单)。
