In ExtJS 4.1 I'm selecting a TreePanel node by its ID like this:
var n = myTreePanel.getStore().getNodeById(id);
myTreePanel.selectPath(n.getPath());
.. which seems like a lot of typing for such a simple operation. Is there a more concise way?
I don't believe there's a more concise way of writing that code that's built-in to the framework. You can always just write your own method and add it to the Tree class.
Ext.tree.Panel.addMembers({
selectPathById: function(id){
var me = this,
node = me.getStore().getNodeById(id);
if(node){
me.selectPath(node.getPath());
}
}
});
/* Later, in your own code */
myTreePanel.selectPathById(id);

is it possible to get a css selector of an WebElement?
eg
var optionSelectors = mutableListOf<String>()
val options = selectWebElement?.findElements(By.cssSelector("option")).orEmpty()
for(option in options){
var optionSelector = option.getSelector()
optionSelectors.add(optionSelector)
}
return toJson(optionSelectors)
Thank you in advance
You can always use Reflection to get foundBy property value like:
Field field = element.getClass().getDeclaredField("foundBy");
field.setAccessible(true);
String foundBy = field.get(element).toString();
However the nature of your question is a little bit weird, given you found the element already you should know its selector, shouldn't you? If you want to interact with the Select option values you can go for the relevant Select class which has getOptions() function.
Also consider going for Page Object Model design pattern, it is one of best practices to keep your test logic separate from UI layer
I'm trying to use a single controller to list multiple similar collections so I can call different templates with the same controller. In fact, right now I have 6 controllers for listing and another 6 for forms but they're all duplicates.
I've made a non-functional plunker just to show how I intend it to work. I've avoided declaring routeProviders because knowing it wouldn't work I tried to make it as straight to the point as I could.

I've seen on stackoverflow how to declare a class with a dynamic name:
var str = "MyClass";
var obj = new window[str];
But as I have not been able to find where it's stored I'm not able to retrieve it.
Does anyone have a hint on how to do this?
You can use Angular's injector to return the service instance you want. For example:
app.controller('NodeListCtrl', function($scope, $location, $injector) {
var modelName = $location.path().split("/")[1];
$scope.modelName = modelName.charAt(0).toUpperCase() + modelName.slice(1);
$scope.nodes = $injector.get($scope.modelName).query();
});
Note: Don't forget to add the $injector to the controller's function signature.

I was trying to achieve exactly what is described in Querying a child collection by multiple values in RavenDB, but when I try to implement it, I can't seem to the location of method Project and class Field as suggested in this snippet from that original question.
public class Products_ByCategoryIdAndSpecs_SortByTotalSold : AbstractIndexCreationTask<Product>
{
public Products_ByCategoryIdAndSpecs_SortByTotalSold()
{
this.Map = products => from product in products
select new
{
product.CategoryId,
_ = Project(product.Specs, spec => new Field("Spec_" + spec.Key, spec.Value, Field.Store.NO, Field.Index.ANALYZED)),
product.TotalSold
};
}
}
I am using unstable build 721 of RavenDB
ErikR,
You need to use the syntax outlined here:
http://ravendb.net/docs/client-api/advanced/dynamic-fields
Looks like you want to use the new .Intersect() feature that has been added by Matt Warren just a few days ago. Seems to be a perfect solution for the question you have linked. Take a look here: http://issues.hibernatingrhinos.com/issue/RavenDB-51
I'm using PetaPoco T4 Template (http://www.hanselman.com/blog/T4TextTemplateTransformationToolkitCodeGenerationBestKeptVisualStudioSecret.aspx), It always converting table names, for example it converts a table named "Media" to "Medium". Have you any idea how can I make it to stop doing that?
Thanks
In your .Database.tt file you can tweak the class names to your liking for each table:
tables["Media"].ClassName = "Media";
I don't know of a way to turn this off everywhere. I believe it is a remnant from the SubSonic inflector. In the SchemaReader classes you will see a call like this:
tbl.ClassName=Inflector.MakeSingular(tbl.CleanName);
You could try changing that to
tbl.ClassName=tbl.CleanName;
To prevent that, I put always this piece of code in the Database.tt file:
// Read schema
var tables = LoadTables();
foreach(Table t in tables)
{
if(!t.Name.ToLower().StartsWith("tablePrefix_"))
{
// Filter tables by prefix
t.Ignore = true;
}
else
{
// This do the trick discussed here
t.ClassName = t.CleanName;
}
}
I need to parse an expressiontree to get a sql where clause.
Aren't there any classes in the .NET FX or any third party library which already have this abilities ?
I mean Linq2SQL, EntityFramework , all of them have to do this, so does anyone know, if there is something that can be reused instead of reinventing the wheel?
MyType.Where(Func<TEntity,bool>((entity)=>entity.Id == 5)))
now i need to get the corresponding string representing a where clause:
where abc.Id = "5"
this is just an simple example. it should also work with logical conjunctions.
I know I can create the expressiontree and parse it on my own, but i think there could be something already existing, which I'm missing
You could create an ExpressionVisitor with the sole purpose of finding and processing the where calls. Making this task very easy to handle.
e.g.,
public class WhereCallVisitor : ExpressionVisitor
{
protected override Expression VisitMethodCall(MethodCallExpression node)
{
var method = node.Method;
if (method.Name == "Where" && method.DeclaringType == typeof(Queryable))
{ // we are in a Queryable.Where() call
ProcessWhereCall(node);
}
return base.VisitMethodCall(node);
}
private void ProcessWhereCall(MethodCallExpression whereCall)
{
// extract the predicate expression
var predicateExpr = ((dynamic)whereCall.Arguments[1]).Operand as LambdaExpression;
// do stuff with predicateExpr
}
// p.s., dynamic used here to simplify the extraction
}
Then to use it:
var query = from row in table
where row.Foo == "Bar"
select row.Baz;
var visitor = new WhereCallVisitor();
visitor.Visit(query.Expression);
