ruby - Rails Activerecord Ambiguous column name on .joins -


here code. work fine if have in :search field or if have in :supplier field if have in both "ambiguous column name 'number'". there way select or something?

@date_from = params[:date_from]  ||     date.today.beginning_of_month.strftime('%m/%d/%y') @date_to = params[:date_to] ||  date.today.strftime('%m/%d/%y') q = "%#{params[:search]}%"  @products = product.where("discont = ? , nonproduct = ?" ,0,0) @products = @products.where('number ?' ,q) if params[:search].present? @products = @products.joins(:supplier_items).where('supplier = ?' ,params[:supplier]) if params[:supplier].present? @products = @products.paginate(page: params[:page], per_page: 25)

just prefix number table name

for example:

@products = product.where(:discount => 0, :nonproduct => 0) @products = @products.where('products.number ?', query)

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
