How can I reuse components and widgets in other Rails applications? Is that a good idea?

Question

I have mini widgets consisting of a model, a controller of several styles and several lines of javascript. Whenever it turns out that I need something like this in the next application that I create, I need to make a copy from the application in which I created them. Needless to say, this is not fun.

So, I heard about component infrastructures such as Cells, Apotomo and Parts that promise to make this work easier, but I could not find any discussions around them or any other important community actions, usage statistics, etc. indicate their acceptance. With the exception of a few blogposts, the community is strangely silent about the components. It makes me think: they are a good idea, and if not, why not?

Reusing code from multiple projects as a whole is a good idea. This reduces the need for maintaining several different sets of code and simplifies the rapid implementation of functions.
