And end?

Rails

Im trying to remember the way in which you can call a method but tell it
not to return and I think it was ‘and end,’ or something like that? An
example would be,

render :partial => ‘test’, and end

Is that correct or did I dream this whole thing? Thanks,

what do you mean “call a method but tell it not to return”? Do you
not want the method to return a value? Do you not want the method to
return at all, thereby blocking the process?

Going by your example and assuming that you just have it a bit wrong…

render :partial => ‘test’ and return

…which will do the render, but then return from the method (this is
just Ruby syntax). The side-effect of this to avoid the rest of the
method and is often used when doing error handling (like:
redirect_to :action => ‘index’ and return)

and return, that’s it. What I want to happen is to check to see if a
condition is met, like to many characters in a text field; if that’s
true display an error message and start over, hence the ‘and return.’
And maybe I might have the concept wrong in my head, but I was thinking
that if it fails why continue, in which case just return. Thanks Rob
