Hi,

i am wondering about the MVC pattern, I havent worked with that for a  
long time and before I break it I would like to ask your advice…

if I have a birthday calender visible in nearly every view where would  
I put the controller? I was thinking about putting the method it into  
application controller… but how do you call that from the view?

Thanks,  
Philipp

Thanks,

so the solution is, just for everyone else facing the same proplems,  
(at least I hope):

Write a helper method

def birthday\_helper (number\_of\_resutls)  
costumers\_with\_upcoming\_birhtday = Costumer.find\_near\_birthday  
costumers\_with\_upcoming\_birhtday= costumers\_with\_upcoming\_birhtday  
[0…number\_of\_resutls]  
end

and then call it from the view

\<% birthday\_helper(10).each do |costumer| %\>

\<%=link\_to costumer.last\_name, costumer %\> \<%=link\_to costumer.birthday, costumer %\>  
\<% end %\>

Thanks for the help!

You might take note that there are a lot of misspellings of  
“birthday” (birhtday), so this code won’t run, but you’ve probably  
already noticed that.

Also, why not make use of a named scope with a parameter instead of a  
helper? Such as:

class Customer  
named\_scope :upcoming\_birthdays, lambda { |number\_of\_results|  
{  
:conditions =\> { [‘your conditions for nearing birthdays’] },  
:limit =\> number\_of\_results  
}  
}  
end

Then in any controller, view or runner you could do  
Customer.upcoming\_birthdays(10)

Hi,

I did end up making a named scope. This feature is really nice!

Thanks guys, really helped me a lot!
