In HAML I have hundreds of lines like the following:
- xyz = someFuncThatReturnsString(''xyz'')
and elsewhere
%div{''id'' => xyz}
The above lines work fine.
- - -
Attempting to keep things DRY (Don''t repeat yourself) I want to do
something like
- eval(otherFuncThatReturnsString(''xyz''))
where
otherFuncThatReturnsString(''xyz'')
returns
"xyz = someFuncThatReturnsString(''xyz'')"
When I do this, HAML no longer sees xyz as being defined when it
attempts to interpret
%div{''id'' => xyz}
What am I doing wrong????

You should define those variables in the controllers and then have them in the views or partials passing them as locals if necessary. -- Leonardo Mateo.

You''re using eval (almost never necessary in Ruby -- send is usually what you want). You''re using eval in the view (breaking MVC). You''re using dynamic element IDs (questionable but sometimes necessary). You''re using camelCase (poor style for Ruby). And most importantly, you''re asking a question that is so abstract that it has little to do with your actual goal. So...what are you actually trying to achieve here? What''s your *actual* code like? What errors or unexpected behavior are you getting?

That is, I have a string named "xyz" and I want to create a variable named xyz and assign the string "abc" to it. -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Please give more information about what you''re actually trying to achieve (rather than the surrogate goal you''ve set for yourself) and we''ll see what we can come up with. (You probably don''t need those variables in the first place.)
