using hash for method parameters

[aidy]

#hi,

#I have a login class

class Login

def withusername, assword)
login.username.setusername)
login.password.setpassword)
end
end

#now in my invocation, I would like to do something like this,

login = Login.new
login.withusername => 'aidy', assword => 'aidy1')

#but I am ensure of my syntax

#regards

#hi,

Are you creating your new language?

Try the following:

class Login

def with(username, password)
@username = username
@password = password
end
end

#now in my invocation, I would like to do something like this,

login = Login.new
login.with("abc", "def")
p login

Try the following:

class Login

def with(username, password)
@username = username
@password = password
end
end


login = Login.new
login.with("abc", "def")
p login

Thanks for the post, but I am trying to explicitly name the parameters
in the call, by attempting to use symbols and a hash, to make things a
little more readable.

So, I would like my call to contain something like this:

login = Login.new
login.withusername => 'aidy', assword => 'aidy1')

cheers

#hi,

class Login

def withusername, assword)
login.username.setusername)
login.password.setpassword)
end
end

#now in my invocation, I would like to do something like this,

login = Login.new
login.withusername => 'aidy', assword => 'aidy1')

You could do it with

<code>
class Login
def with(params)
@username = params[:username]
@password = params[assword]
end
end

login = Login.new
login.withusername => 'aidy', assword => 'aidy1')
login.inspect # => "#<Login:0x24090 @password=\"aidy1\", @username=
\"aidy\">"
</code>

but I'd go with

<code>
class Login
def initialize(params)
@username = params[:username]
@password = params[assword]
end
end

login = Login.newusername => 'aidy', assword => 'aidy1')
login.inspect # => "#<Login:0x23d48 @password=\"aidy1\", @username=
\"aidy\">"
</code>

as being simpler.

So, I would like my call to contain something like this:
=20
login =3D Login.new
login.withusername =3D> 'aidy', assword =3D> 'aidy1')
=20

You can use something like this:

def with params =3D {}
params.each do |key,value|
m =3D "#{key}=3D"
self.send(m, value) if self.respond_to?(m)
end
end

but you should build-in additional checks which will filter out possibly
unsafe assignments, which you would not want here.

Another thing, you may want to call it 'initialize', to be able to use:

login =3D Login.new :username =3D> 'username', assword =3D> 'pass'

BTW this is similiar to how ActiveRecord works.
