Hi,
The code below works perfectly but is so repetitive I feel there must be
a standard way to refactor it in this situation. I am learning on my
own so am wondering how more experienced programmers would do this. Any
examples would be appreciated.
def reset_to_previous
contents_history = Profile.find(:first, conditions: [ "user_id
?", current_user.id])
if contents_history[:last_minisection_id].present?
session[:minisection_id] contents_history[:last_minisection_id]
session[:subsection_id] contents_history[:last_subsection_id]
session[:section_id] = contents_history[:last_section_id]
session[:chapter_id] = contents_history[:last_chapter_id]
session[:book_id] = contents_history[:last_book_id]
session[:subject_id] = contents_history[:last_subject_id]
session[:subject_title] Subject.find(session[:subject_id]).title
session[:book_title] = Book.find(session[:book_id]).title
session[:chapter_title] Chapter.find(session[:chapter_id]).title
session[:section_title] Section.find(session[:section_id]).title
session[:subsection_title]
Subsection.find(session[:subsection_id]).title
session[:minisection_title]
Minisection.find(session[:minisection_id]).title
redirect_to(:controller => "contents", :action =>
"index_minisections", :subsection_id => session[:subsection_id])
elsif contents_history[:last_subsection_id].present?
session[:subsection_id] contents_history[:last_subsection_id]
session[:section_id] = contents_history[:last_section_id]
session[:chapter_id] = contents_history[:last_chapter_id]
session[:book_id] = contents_history[:last_book_id]
session[:subject_id] = contents_history[:last_subject_id]
session[:subject_title] Subject.find(session[:subject_id]).title
session[:book_title] = Book.find(session[:book_id]).title
session[:chapter_title] Chapter.find(session[:chapter_id]).title
session[:section_title] Section.find(session[:section_id]).title
session[:subsection_title]
Subsection.find(session[:subsection_id]).title
redirect_to(:controller => "contents", :action =>
"index_subsections", :section_id => session[:section_id])
elsif contents_history[:last_section_id].present?
session[:section_id] = contents_history[:last_section_id]
session[:chapter_id] = contents_history[:last_chapter_id]
session[:book_id] = contents_history[:last_book_id]
session[:subject_id] = contents_history[:last_subject_id]
session[:subject_title] Subject.find(session[:subject_id]).title
session[:book_title] = Book.find(session[:book_id]).title
session[:chapter_title] Chapter.find(session[:chapter_id]).title
session[:section_title] Section.find(session[:section_id]).title
redirect_to(:controller => "contents", :action =>
"index_sections", :chapter_id => session[:chapter_id])
elsif contents_history[:last_chapter_id].present?
session[:chapter_id] = contents_history[:last_chapter_id]
session[:book_id] = contents_history[:last_book_id]
session[:subject_id] = contents_history[:last_subject_id]
session[:subject_title] Subject.find(session[:subject_id]).title
session[:book_title] = Book.find(session[:book_id]).title
session[:chapter_title] Chapter.find(session[:chapter_id]).title
redirect_to(:controller => "contents", :action =>
"index_chapters", :book_id => session[:book_id])
elsif contents_history[:last_book_id].present?
session[:book_id] = contents_history[:last_book_id]
session[:subject_id] = contents_history[:last_subject_id]
session[:subject_title] Subject.find(session[:subject_id]).title
session[:book_title] = Book.find(session[:book_id]).title
redirect_to(:controller => "contents", :action =>
"index_books",
:subject_id => session[:subject_id])
elsif contents_history[:last_subject_id].present?
session[:subject_id] = contents_history[:last_subject_id]
session[:subject_title] Subject.find(session[:subject_id]).title
redirect_to(:controller => "subjects", :action =>
"index")
end
end
Thanks,
Dave
