Question

I can’t see the difference in the ruby console between Model.all and Model.where(:source_id => 2). My problem is with the «all» instruction I can do .each on the array and with Model.where I can’t do .each

Working

# controller.rb
@results = Adress.all

#view.haml
- @results.each do |result|

Not-Working

# controller.rb
@results = Adress.where(:source_id => 2)

#view.haml
- @results.each do |result|

Error message –> undefined method `each’ for nil:NilClass

In console –> Adress.where(:source_id => 2) it’s works

——- MY BAD, THE SOLUTION ——

my view was trying to do .each on inexistent variable…….

THE PROBLEM

@Adress = Adress.where(:arrondissement_id => params[:arrondissement])

THE SOLUTION

@results = Adress.where(:arrondissement_id => params[:arrondissement])
