Property binding vs attribute interpolation

Property binding like [trueValue]=”…” evaluates the expression “…” and assigns the value “true” evaluates to the value true “Y” is unknown. There is no internal Y value in TypeScript and no property in the component class instance, which is the scope of template binding. In this case you would want [trueValue]=”‘Y'” Note the additional quotes … Read more

What is the best way to do automatic attribute assignment in Python, and is it a good idea?

There are some things about the autoassign code that bug me (mostly stylistic, but one more serious problem): autoassign does not assign an ‘args’ attribute: class Foo(object): @autoassign def __init__(self,a,b,c=False,*args): pass a=Foo(‘IBM’,’/tmp’,True, 100, 101) print(a.args) # AttributeError: ‘Foo’ object has no attribute ‘args’ autoassign acts like a decorator. But autoassign(*argnames) calls a function which returns … Read more

Django error object has no attribute ‘update’

The reason for this error is that .get() returns an individual object and .update() only works on querysets, such as what would be returned with .filter() instead of .get(). If you are using .get(), then .update() will not work. You will need to save the information to the object manually: archivo = archivo.objects.get(archivo_id=procesar) archivo.archivo_registros = … Read more

What does @AttributeOverride mean?

It’s saying that the attributes that make up the embedded id may have predefined (through explicit or implicit mappings) column names. By using the @AttributeOverride you’re saying “ignore what other information you have with regard to what column it is stored in, and use the one I specify here”.

Determine if CSS property is set to a certain value?

Use if( $(“#test”).css(‘display’) == ‘block’) { I’m fairly sure .css(), returning a calculated value, will always return a lower case result – the docs say nothing on this. To make totally sure, you could do a if( $(“#test”).css(‘display’).toLowerCase() == ‘block’) { while you can rely on display giving reliable results, note that some CSS properties … Read more

Is there any attribute relating to AJAX to be set for ASP.NET MVC controller actions?

I don’t think there is built in attribute for ajax, but you can create your own AjaxOnly filter like this: public class AjaxOnlyAttribute : ActionMethodSelectorAttribute { public override bool IsValidForRequest(ControllerContext controllerContext, System.Reflection.MethodInfo methodInfo) { return controllerContext.RequestContext.HttpContext.Request.IsAjaxRequest(); } } And decorate your action methods like this: [AjaxOnly] public ActionResult AjaxMethod() { } See Also: ASP.NET MVC … Read more

HttpPost vs HttpGet attributes in MVC: Why use HttpPost?

Imagine the following: [HttpGet] public ActionResult Edit(int id) { … } [HttpPost] public ActionResult Edit(MyEditViewModel myEditViewModel) { … } This wouldn’t be possible unless the ActionMethodSelectorAttributes HttpGet and HttpPost where used. This makes it really simple to create an edit view. All the action links just points right back to the controller. If the view … Read more
