我目前在我的应用程序中有以下内容,每当有$ http请求运行时显示加载动画,然后隐藏在最后;
app.config(['$httpProvider', function ($httpProvider) {
var $http,
interceptor = ['$q', '$injector', function ($q, $injector) {
var error;
function response(response) {
// get $http via $injector because of circular dependency problem
$http = $http || $injector.get('$http');
if ($http.pendingRequests.length < 1) {
$('#loadingWidget').hide();
}
return response;
}
function responseError(response) {
if (response.status == 401) {
alert("You have been logged out or have tried to access a restricted area, redirecting to the login screen...");
window.location = globals.siteUrl + 'login';
} else { …我遇到了一个奇怪的问题，我似乎无法在 django 的表单中设置其中一个字段的初始值。
我的模型字段是：
section = models.CharField(max_length=255, choices=(('Application', 'Application'),('Properly Made', 'Properly Made'), ('Changes Application', 'Changes Application'), ('Changes Approval', 'Changes Approval'), ('Changes Withdrawal', 'Changes Withdrawal'), ('Changes Extension', 'Changes Extension')))
我的表单代码是：
class FeeChargeForm(forms.ModelForm):
class Meta:
model = FeeCharge
# exclude = [] # uncomment this line and specify any field to exclude it from the form
def __init__(self, *args, **kwargs):
super(FeeChargeForm, self).__init__(*args, **kwargs)
self.fields['received_date'] = forms.DateField(('%d/%m/%Y',), widget=forms.DateTimeInput(format='%d/%m/%Y', attrs={'class': 'date'}))
self.fields['comments'].widget.attrs['class']='html'
self.fields['infrastructure_comments'].widget.attrs['class']='html'
我的视图代码是：
form = FeeChargeForm(request.POST or None)
form.fields['section'].initial = section
其中 section …
"<unknown>:1:0: syntax error"当响应看起来像这样时,有谁知道为什么我会从python suds调用得到一个？

例如:
class MyModel(models.Model)
fee = models.DecimalField()
fee_gst = models.DecimalField()
我想我可以在模型中添加@staticmethod:
@staticmethod
def fee_total(self):
return self.fee + self.fee_gst
但我似乎无法使用以下方法访问模型的"fee_total"字段:
model = MyModel.objects.get(pk=1)
total = model.fee_total
我有什么想法我做错了吗？
干杯
我正在将旧的遗留PHP系统转换为Flask + SQLAlchemy,并想知道如何构建以下内容:
我有一个模特:
class Invoice(db.Model):
paidtodate = db.Column(DECIMAL(10,2))
fullinvoiceamount = db.Column(DECIMAL(10,2))
invoiceamount = db.Column(DECIMAL(10,2))
invoicetype = db.Column(db.String(10))
acis_cost = db.Column(DECIMAL(10,2))
我需要运行的查询是:
SELECT COUNT(*) AS the_count, sum(if(paidtodate>0,paidtodate,if(invoicetype='CPCN' or invoicetype='CPON' or invoicetype='CBCN' or invoicetype='CBON' or invoicetype='CPUB' or invoicetype='CPGU' or invoicetype='CPSO',invoiceamount,
fullinvoiceamount))) AS amount,
SUM(acis_cost) AS cost, (SUM(if(paidtodate>0,paidtodate,invoiceamount))-SUM(acis_cost)) AS profit FROM tblclientinvoices
是否有SQLAlchemyish方法来构造此查询？ - 我尝试使用SQlAlchemy谷歌搜索Mysql IF的声明,但画了空白.
非常感谢!
快问,
我可以使用输出表单字段的值
{{ form.field.value }}
但我似乎无法在if语句中检查该值.
{% if form.field.value == 'whatever' %}
总是失败..任何想法？
该字段是布尔类型字段.
编辑 - 下面给出的答案适用于某些领域..这是我想要做的;
表单字段是模型中的boolen字段,在表单中使用此代码;
self.fields['information_request'] = forms.TypedChoiceField(choices=((True, 'Yes'), (False, 'No')), widget=forms.RadioSelect, coerce=lambda x: x and (x.lower() != 'false'))
使用{{form.information_request.value}}时输出是正确的(例如,True或False) - 但是当我在模板中的IF语句中使用它时 - 它永远不会起作用..
嘿家伙我正在将一些数据发布到服务器然后基于几个变量再次发布到循环内的不同URL.
到目前为止我用的是一个例子:
$scope.items = [{'name':'Test1','hasd':1,'hase':1},{'name':'Test2','hasd':0,'hase':1}];
var promises = [];
angular.forEach($scope.items,function(obj) {
promises.push($http({
type:'post',
url:'test',
data:obj
}).then(function(response) {
if(response.status==201) {
//do another http call
if(obj.hasd==1) {
$http({}).then(function() {
var something=1;
});
}
}
}));
$q.all(promises).then(function(){
alert('done');
});
我遇到的问题是,它只是查看最初的$ http呼叫的承诺,而不是任何内部呼叫.有没有办法将所有$ http调用添加到循环内的promise中？
干杯,本
我已经尝试了一段时间才弄清楚为什么我永远无法从jquery获得"最接近"的功能.
说我有这个代码;
<form>
<input type='text' name='q'>
<a href='javascript:void(0);' id='search_items'>Search</a>
</form>
为什么以下始终警告"未定义"？
$("#search_items").bind('click', function () {
var q = $(this).closest("input[name=q]").val();
alert(q);
});
提前致谢!干杯,本
