Question

I’m trying to do something like:

if filter_1
  @field = @field.where()
else
  @field = @field.where()
end

if filter_2
  @field = @field.order()
end

etc.

But how do I init @field with an empty query? I tried @field = Field.all but that gives an array so not allowing chaining.

Try scopedon Model class e.g.

@fields =  Field.scoped
@fields = @fields.where("your conditions") if filter_1
@fields = @fiels.order("your conditions") if filter_2
