I need to provide users a link to download an user_guide.txt file.
Currently the user_guide.html.erb looks like this.
Dear <%=@user.name %>,
Please visit <%=@unlocking_webiste %> site.
the point is that the file has some variables which needs to be
replaced then user should be able to download these files and use
I can find ways to download a static file but in this case how should
I code such that users are able to download the customized files.
