how to structure this HAML code to not include some <div>
if the HAML is:
.class1
.class2
.class3
%div
content... many lines
How can it be made so that it doesn''t respond with class1 and class2 if
it is Ajax?
- if !request.xhr?
.class1
.class2
.class3
%div
content... many lines
won''t work, because if not Ajax, then class3 is not a child of class2.
It might have to be something like
- if !request.xhr?
.class1
.class2
.class3
%div
content... many lines
- else
.class3
%div
content... many lines
and it is repeating a lot of code. Can it be structure within the same
file? Or the second part made into a partial?

First of all, do you need to nest the divs at all? Remember that one element can have multiple classes, so .class1.class2.class3 is possible. If not, then can you extract the .class1 and .class2 into a layout?> > - if !request.xhr? > .class1 > .class2 > > .class3 > %div > content... many lines > > won''t work, because if not Ajax, then class3 is not a child of class2. > It might have to be something like > > - if !request.xhr? > .class1 > .class2 > .class3 > %div > content... many lines > - else > .class3 > %div > content... many lines > > and it is repeating a lot of code.

Re: how to structure this HAML code to not include some <div>
let''s assume class1, 2, and 3, etc all have their functions, so we need all of them. the 3rd code piece is what we want: class 3 should be nested inside of class2, which is what this question is all about. why is using "request.xhr?" inside of a view not a good idea? if so, you should only use it in controller and why? -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

The view should only know what the controller tells it.> if so, > you should only use it in controller and why?Because according to Rails MVC design principles, views should be as dumb as possible. The request object is really none of the view''s business -- all the view should do is display the data the controller passes it.
