Hello,
I''m fairly new to Ruby, cucumber, and WebDriver and ran into what
seems to be a Ruby issue. It doesn''t seem to be handling my .intern
or .to_sym in this mock-up inline form, ele.send_keys(x[i],
x[i].intern, x[i], x[i].intern)
I tried both intern and to_sym with the same result, as expected.
I''m trying to parse a string and output a string with symbol
parameter.
Input string: ''Student One'', :return, ''Student
Two'', :return
Output: ele.send_keys(''Student One'', :return,
''Student Two'', :return)
def fill_in(field_name,text)
# ele = Find.Element(find_locator(:text_field,field_name))
# ele.clear
#The above correctly obtains the text:
# ''Student One'', :return, ''Student Two'',
:return
#Therefore, hard code to test:
text = "''Student One'', :return, ''Student
Two'', :return"
items = text.split(/,\s?/)
ele.send_keys(items.each_index {|x|
next if x % 2 == 1
if (x<items.size-1) then items[x] +'', '' else items[x]
end
items[x+1].intern
})
end
Output
''Student One'', :return, ''Student Two'',
:return
When I run this instead of the symbols acting like symbols they act
like strings, the :returns are not resolved.
However, hard coded strings and symbols like the following work as
expected:
ele.send_keys(''Student One'', :return, ''Student
Two'', :return)
Output
Student One
Student Two

You''re not assigning any new values to it, so of course .intern isn''t having any effect. - not sure exactly what you''re doing with the +'', '' there, but I suspect you really want Ruby''s "splat" operator. It takes an array and fills in the arguments to the method with each element (simplified description). Your code would end up looking like: items = text.split(/,\s?/) ele.send_keys(*items.map {|x| case x when /^''(.*)''$/ then $1 # "''Student One''" => "Student One" when /^:(.*)$/ then $1.to_sym # ":return" => :return end }) --Matt Jones -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

From your comment it looks like I may need to understand why I would need
to assign values return is already part of the text so my assumption is
that I just have to .to_sym it. However, if I have to assign and deliver
something that would change quite a bit.
Clarification.
The desired resulting line is:
ele.send_keys(''Student One'', :return, ''Student
Two'', :return)
Basically "''Student One'', :return, ''Student
Two'', :return" is parsed to
result in itself except with the symbols understood as symbol type.
In the original:
x[0] == ''Student One''
'', '' is added since it is not the last element
x[1] == ''return'' output as x[1].to_sym which adds the :
itself.
'', '' is added since it is not the last element
Pattern repeats.
Mat, your idea has made the :return do what it is supposed to but now
I''m
unable to get the text to output. All that is coming out is the symbols
even though puts on the text line shows it should be displaying in the
following:
(I added .to_s even though I shouldn''t have to just to be sure the type
hadn''t changed.)
items = text.split(/,\s?/)
ele.send_keys(*items.map {|x|
case x
when /^.*''.*/ then $1.to_s+'', ''; puts
''hit a quote'' #
"''Student One''" => "Student One" (puts
shows is hit but text not
displaying on screen)
when /^:(.*)$/ then $1.to_sym # ":return" =>
:return
(outputting but requires comma?)
else $1.to_s #return unknowns as is (nothing should hit this)
end
})
Is it because the commas are stripped? I tried adding them back in with +
'' , '' on the to_sym line but received the error,
''undefined method `+'' for
:return:Symbol''
I also am unsure how the case structure can detect if the element is
''last''
so that it doesn''t add the comma on the last element.

An example: def foo(arg1, arg2, arg3) puts "arg1 is #{arg1.inspect}" puts "arg2 is #{arg2.inspect}" puts "arg3 is #{arg3.inspect}" end a = [1,2,3] Then calling: foo(*a) will result in: arg1 is 1 arg2 is 2 arg3 is 3> Mat, your idea has made the :return do what it is supposed to but now I''m > unable to get the text to output.
