I have 2 rails applications - A and B. They have multiple dependencies that are incompatible to each other. Besides appliaction A is created for rails 3 and appliaction B is created for rails 4.
I would like to display content of the appliaction A, and take small part from appliaction B and embed it into rendered view. I have not found other way than merging these 2 appliacations toegether. Unfortunately it is really complicated and can consume a lot of time.
Is there any other way to do it? I would not like to use iframes.
