I am importing the data from a spreadsheet to the app database.
The data is parsed by rows. Each parsed row looks like:
{:department=>{:school=>"Graduate School of Business", :name=>"Graduate School of Business", :program=>"MBA Program", :url=>"http://www.gsb.stanford.edu/mba", :intro=>"The Stanford MBA Program is a two-year, full-time, residential program.", :students_number=>"Approximately 80 annually", :students_with_aids_number=>nil, :gre_scroe=>nil, :toefl_score=>nil, :world_rank=>nil, :us_rank=>nil, :without_aid_deadline=>nil, :with_aid_deadline=>nil, :salary=>nil, :institute_id=>1}}
To create a department:
# att is the hash shown above department = Department.new(department_params(att)) if !department.save puts "Error: \n department can't be save: #{department.errors.full_messages}" end
def department_params params params.require(:department).permit(:name,:url,:institute_id) end
But I got the error:
no implicit conversion of Symbol into String which points to
params.require(:department).permit(:name,:url,:institute_id)
How could I fix it? Thanks!
