Dynamically Create Class Attributes with attr_accessor


Tag : ruby , By : unadopted

I wish this help you One way (there are others) is to use instance_variable_set and instance_variable_get as so:
class Test
    def create_method( name, &block )
        self.class.send( :define_method, name, &block )
    end

    def create_attr( name )
        create_method( "#{name}=".to_sym ) { |val| 
            instance_variable_set( "@" + name, val)
        }

        create_method( name.to_sym ) { 
            instance_variable_get( "@" + name ) 
        }
    end
end

t = Test.new
t.create_attr( "bob" )
t.bob = "hello"
puts t.bob

Create Python class where the attributes is defined dynamically

I wish did fix the issue. The easiest way to do this is to assign the keyword argument dict to the __dict__ attribute of the class:
class Person(object):
    def __init__(self, **kw):
        self.__dict__ = kw
person = Person(name='Joe')
print person.name
Joe
def add_attributes(self, **kw):
    self.__dict__.update(kw)

create attributes of buttons dynamically depending on div class

I hope this helps . Change your buttons so that they look something like this (the attributes are the important things):
<button class="image-button" data-image="bg1.jpg">Text</button>
$(".image-button").click(function() { 
    var url = 'url(' + $(this).data('image') + ')';

    $('#firstdiv').css('background-image', url);
});

python dynamically create attributes class

wish of those help i = "test" is actually converted to {'i':'test'} when passed to **kwargs inside add_attributes, so you need to do something like this:
for i in my_list:
    c.add_attributes(**{ i : "test"})

Create class attributes dynamically in Scala

it helps some times It is possible to achieve this with macros, and there are two techniques for that with a different set of trade-offs. Refer to our joint talk with Travis Brown for more information and a link to an example implementation: https://github.com/travisbrown/type-provider-examples/blob/master/docs/scalar-2014-slides.pdf?raw=true.
