   attributes
 end

 def self.trim_non_ascii(string)

Issue #328

This was an issue to fix the functionality of Insert any new members into existing team. This was due to faulty handling of the option handle_dups and incorrect checking of parameters.
Code was modified to ensure minimal impact to existing testcases and functionalities. Code:

     name = handle_duplicate(team, name, id, options["handle_dups"], teamtype)

After fixing changes


Issue #329

This was a request to add an option to rename existing team if there was a conflict in the team name.
New code introduced was as follows:
In start.html.erb

         <option value="rename_existing">rename the existing team and import</option>

In team.rb

   # E1938: Added handling for renaming old team when conflict arises
   if handle_dups == "rename_existing"
     if teamtype.is_a?(CourseTeam.class)
       team.update(name: self.generate_team_name(Course.find(id).name))
     elsif  teamtype.is_a?(AssignmentTeam.class)
       team.update(name: self.generate_team_name(Assignment.find(id).name))
     end
     return name
   end
