config.threadsafe! for pdf generating with images needed on development #14331

Hi, i'm working on a project with Rails 4.0.3 over a db legacy with images stored in blob field and I need to get some pdf as products catalog.
In development mode I get pdf with images if I set config.threadsafe!, also the process hang. In production all goes well.

But if I use this setting, the controllers changes I make doesn't take effect until i restart the server !!
for example:
trying for pagination , I modify the per_page parameter in index action controller, then F5 in browser and the view is the same, with the old number of elements.
If i remove the config.threadsafe! all goes as expected for development: every time I modify the code then F5 in browser I show the changes that affect views.


On reading some pages on RailsGuides I've seen that threadsafe! enable the cache_classes parameter.
That explain my issue!
But remain the fact that I should like to obtain the pdf with images also on development.
