I don't have much idea about what problem you are trying to describe, I presume English is not your first language and understand it can be difficult to explain a problem clearly. If I am right then you have an action branch in the branches controller but have the problem that in order for data to be seen in the view then you have to setup variables in that action. If you don't want to set them up there then possibly a before_filter is what you want. If I am not understanding the problem correctly then please try again to explain it. Cut your example down to the absolute minimum code required and show what you are trying to do and what the problem is. After writing your description of the problem imagine yourself as someone who knows nothing about your requirement, read your description carefully, and make sure the description of the problem is clear.
