我有一个configuraiton页面,我在其中创建,编辑和删除不同类型的东西。现在问题出现在你创建一个新的enitity,并选择“编辑”相同。然后它不会发现有一个变化,当我试图保存时没有任何反应。
请记住保存和删除工作,以及编辑旧实体。旧的我的意思是系统曾刷新一次。我认为必须是临时id或缓存?
运行所有内容的方法是 editCompanyType(),然后运行保存()
短版
当我创建新实体时,然后选择对其进行编辑。 它不会保存新编辑的值,而是在屏幕上更新值本身。
来自我的ViewModel我在创建新实体
时运行此命令var companyTypeTemp = configunitofwork.configcompanytypesrepository.createEntity();
加载我的模态并返回结果。并在需要时保存。
var diag = new genericModal("", 'företagstyp');
diag.viewUrl = 'views/config/genericModal';
app.showDialog(diag).then(function (diagResult) {
if (diagResult === 'update') {
companyTypeTemp.company_type_text = diag.generic_type;
Save();
} else {
logger.log("Du gjorde inga ändringar!", null, "panel", true);
}
});
储蓄就在这里。
function Save() {
if (!configunitofwork.hasChanges()) {
return true;
}
configunitofwork.commit()
.then(function () {
refreshCompanyTypes(companyTypes);
logger.logSuccess("Företagstypen sparades!", null, "panel", true);
});
return true;
}
现在,当我尝试编辑新创建的实体时,它失败了,它不会发现任何变化..?
我将我的行动绑定到视图
var bindAction = function (view) {
$(view).on('click', '.editCompanyType', function () {
var company_type = ko.dataFor(this);
editCompanyType(company_type);
});
};
所以当我点击我的实体时,我将运行我的编辑方法
var editCompanyType = function (company_type) {
var diag = new genericModal(company_type.company_type_text, 'företagstyp');
diag.viewUrl = 'views/config/genericModal';
app.showDialog(diag).then(function (diagResult) {
if (diagResult === 'update') {
//update
Save();
} else if (diagResult === 'delete') {
//delete
deleteCompanyType(company_type);
}
else {
logger.log("Du gjorde inga ändringar!", null, "panel", true);
}
});
};
这将依次加载我的模态,它是通用的并且获取文本的数据,以及表示当前类型上下文的字符串。
var genericModal = function (genericType, genericnametype) {
this.generic_type = ko.observable(genericType);
this.placeholder_text = 'Skriv din ' + genericnametype;
this.modal_title = ko.observable('Lägg till ' + genericnametype);
//Uppercase machine
this.modal_toastr_text = genericnametype;
this.modal_header = genericnametype[0].toUpperCase() + genericnametype.slice(1);
this.update_button_text = ko.observable('Lägg till ' + genericnametype);
this.delete_button_text = ko.observable('Ta bort ' + genericnametype);
this.deleteAllowed = ko.observable(false);
this.update_icon_class = 'fa fa-gear';
this.delete_icon_class = 'fa fa-eject';
if (genericType != "") {
this.generic_type = genericType;
this.modal_title = ko.observable('Uppdatera ' + genericnametype);
this.update_button_text = ko.observable('Uppdatera ' + genericnametype);
this.deleteAllowed(true);
}
};
我绑定this.generic_type错了吗?
在HTML中,它就像这样绑定。

答案 0 :(得分:0)
我解决了它,虽然我认为这违反了KO和Breezes的原则。
解决方案是触发 setModified();
我添加了这个我的编辑方法。
if (diagResult === 'update') {
//update
company_type.entityAspect.setModified();
Save();
}
强制.hasChanged返回true,并启动保存。
还有其他办法吗?
