Problem manipulating params for login

Rails
1

I can get this to work in the console by subbing a string for
params[:person][:login_name] but my application won’t “catch” and
convert the params in the development site. Here is the login function:

  #find user record by unique name
  name_array = %w{params[:person][:login_name]}
  name_array.each {|name| name.gsub!(/\"/, "")}
  @person = Person.find(:first,
                        :conditions => ["first_name = ? and

last_name = ?", name_array[0], name_array[1]])

People log in with their full name like, “Bob S…” The database
contains first_name and last_name columns. In the console when I
substitute “Bob S.” for params[:person][:login_name] the record is
retrieved normally. But it doesn’t work with params. Any suggestions?

This variation doesn’t work either:

  #find user record by unique email
  name = params[:person][:login_name]
  name_array = []
  name_array = %w{name}
  name_array.each {|name| name.gsub!(/\"/, "")}
  @person = Person.find(:first,
                        :conditions => ["first_name = ? and

last_name = ?", name_array[0], name_array[1]])

name = params[:person][:login_name]
name_array = []
name_array = %w{name}
name_array.each {|name| name.gsub!(/"/, “”)}
@person = Person.find(:first,
:conditions => [“first_name = ? and
last_name = ?”, name_array[0], name_array[1]])

Use:

name_array = params[:person][:login_name].split(/ /)

params[:person][:login_name]
=> “John S.”

name_array = params[:person][:login_name].split(/ /)
=> [“John”, “Smith”]

With %w, no substitutions are done on the inputs – i.e. they are
assumed to
be literal string values. With %W substitutions can be done but they
aren’t
split afterwards.

name_array = %w{params[:person][:login_name]}
=> [“params[:person][:login_name]”]

name_array = %w{#{params[:person][:login_name]}}
=> ["#{params[:person][:login_name]}"]

name_array = %W{params[:person][:login_name]}
=> [“params[:person][:login_name]”]

name_array = %W{#{params[:person][:login_name]}}
=> [“John S.”]
