Question

When I was developing my project on my local file I had this line in code which worked correctly:

@json = Location.qty_of_deliv_from(params[:from_rc])
  .qty_of_deliv_to(params[:to_rc])

When I deployd with passenger I get a syntax error on this line which goes avay if I have all the code in the same line:

@json = Location.qty_of_deliv_from(params[:from_rc]).qty_of_deliv_to(params[:to_rc])

Is this a known issue?

Answer 1

Perhaps your server’s ruby version is different and parses differently?

In any case, in Ruby, when writing multiline code you typically want to make sure your lines to be wrapped are syntactically incomplete, so as not to confuse the parser, e.g. by using a hanging dot, instead.

Location.qty_of_deliv_from(params[:form_rc]).
  qty_of_deliv_to(params[:to_rc])

Or you can use the backslash to escape the new line:

Location.qty_of_deliv_from(params[:form_rc]) \
  .qty_of_deliv_to(params[:to_rc])
