function assign(obj, prop, value) { if (typeof prop === “string”) prop = prop.split(“.”); if (prop.length > 1) { var e = prop.shift(); assign(obj[e] = Object.prototype.toString.call(obj[e]) === “[object Object]” ? obj[e] : {}, prop, value); } else obj[prop[0]] = value; } var obj = {}, propName = “foo.bar.foobar”; assign(obj, propName, “Value”);
You’ll have to create a new one since OrderedDict is sorted by insertion order. In your case the code would look like this: foo = OrderedDict(sorted(foo.items(), key=lambda x: x[1][‘depth’])) See http://docs.python.org/dev/library/collections.html#ordereddict-examples-and-recipes for more examples. Note for Python 2 you will need to use .iteritems() instead of .items().
For rails 3.0.0+ or higher version there is the deep_merge function for ActiveSupport that does exactly what you ask for.
you have to call a function before it can return anything. function mainFunction() { function subFunction() { var str = “foo”; return str; } return subFunction(); } var test = mainFunction(); alert(test); Or: function mainFunction() { function subFunction() { var str = “foo”; return str; } return subFunction; } var test = mainFunction(); alert( test() … Read more
The fixing and the positioning are two separate things. They’re positioned the same as absolutely positioned elements: relative to their containing block. But in contrast with absolutely positioned elements, they remain fixed to that position with respect to the viewport (i.e. they don’t move when scrolling): http://www.w3.org/TR/CSS2/visuren.html#propdef-position The box’s position is calculated according to the … Read more
Block level elements (to which h4 belongs) are not allowed inside inline elements, and will cause undefined behaviour. You can use span elements instead.
If you are using any spreadsheet application there is a basic function if() with syntax: if(<condition>, <yes>, <no>) Syntax is exactly the same for ifelse() in R: ifelse(<condition>, <yes>, <no>) The only difference to if() in spreadsheet application is that R ifelse() is vectorized (takes vectors as input and return vector on output). Consider the … Read more
Just to complete the original answer, I think it is clearer adding the nested style inside the parent like that: <Style x:Key=”WindowHeader” TargetType=”DockPanel” > <Setter Property=”Background” Value=”AntiqueWhite”></Setter> <Style.Resources> <Style TargetType=”Image”> <Setter Property=”Margin” Value=”6″></Setter> <Setter Property=”Width” Value=”36″></Setter> <Setter Property=”Height” Value=”36″></Setter> </Style> <Style TargetType=”TextBlock”> <Setter Property=”TextWrapping” Value=”Wrap”></Setter> </Style> </Style.Resources> </Style>
Use :inverse_of and validates_presence_of :parent. This should fix your validation problem. class Dungeon < ActiveRecord::Base has_many :traps, :inverse_of => :dungeon end class Trap < ActiveRecord::Base belongs_to :dungeon, :inverse_of => :traps validates_presence_of :dungeon end http://apidock.com/rails/ActiveModel/Validations/HelperMethods/validates_presence_of https://github.com/rails/rails/blob/73f2d37505025a446bb5314a090f412d0fceb8ca/activerecord/test/cases/nested_attributes_test.rb
You may have to use the new yield from, available since Python 3.3, known as “delegated generator”. If I understood the question correctly, I came to the same issue, and found an answer elsewhere. I wanted to do something like this: def f(): def g(): do_something() yield x … yield y do_some_other_thing() yield a … … Read more
