I get the error message
syntax error, unexpected tIDENTIFIER, expecting ')'
leg = legislators_by_zipcode(zipcode)
when executing the code below:
require 'csv'
require 'sunlight/congress'
Sunlight::Congress.api_key = "c..."
def clean_zipcode(x)
x = x.to_s.rjust(5, "0")[0..4]
end
def legislators_by_zipcode(zipcode)
legislators = Sunlight::Congress::Legislator.by_zipcode(zipcode)
legislator_names = legislators.collect do |legislator|
"#{legislator.first_name} #{legislator.last_name}"
end
legislator_names.join(", ")
end
contents = CSV.open "event_attendees.csv", headers: true, header_converters: :symbol
contents.each do |row|
name = row[:first_name]
zipcode = clean_zipcode(row[:zipcode]
leg = legislators_by_zipcode(zipcode)
puts "#{name} #{zipcode} #{leg}"
You missed the closing brace()) here zipcode = clean_zipcode(row[:zipcode] in your code.Re write it as zipcode = clean_zipcode(row[:zipcode]).

def get_xml
path = "ddd-66252.pdf" // in public
way = File.basename(path)
diff = File.read(path)
render :xml => diff
end
How i can get file from path and need to look like file
Assuming you are using Ruby on Rails because you mention a public folder and have a render method in your code. In Ruby on Rails you can use send_file in your controller like this to send files to the browser:
def send_pdf
send_file(
Rails.root.join('public', 'ddd-66252.pdf'),
filename: 'ddd-66252.pdf',
type: 'application/pdf'
)
end

I have the following code:
def parse_package_url package, directory
branchget = package.split '#'
branch = branchget.length > 1 ? branchget[1] : false
siteget = branchget[0].split(':')
site = siteget.length > 1 ? siteget[0] : 'gitlab'
repoget = (siteget.length > 1 ? siteget[1] : siteget[0]).split '/'
packagename = repoget[1]
packageuser = repoget[0]
path = "#{directory}/#{packagename}"
{
:branch => branch,
:site => site,
:name => packagename,
:user => packageuser
:path => path,
:repo => repoget.join('/')
}
end
Upon running this code, I get the following errors:
syntax error, unexpected tSYMBEG, expecting '}' (SyntaxError)
:path => path,
^
syntax error, unexpected tASSOC, expecting tCOLON2 or '[' or '.'
:repo => repoget.join('/')
syntax error, unexpected '}', expecting keyword_end
I cannot spot my syntax mistake in this code, and would appreciate if somebody could point it out.
You're missing the comma after :user => packageuser which is causing a syntax error. With errors like these, years of staring have taught me the issue is often with one line above the line number Ruby gives you.

Please can someone help me?
You're doing a ternary if but you're missing the else clause.
Change
(value == true) ? key.upcase"#{key.upcase}=#{value}"
to
value ? key.upcase : "#{key.upcase}=#{value}"
And then read How do I use the conditional operator in Ruby

I have the URL http://localhost:3000/en/invest_offers?utf8=blahblahblah. How can I get ?utf8=blahblahblah part of the URL? Thanks!
Do as below using URI::Generic.query:
require 'uri'
URI("http://localhost:3000/en/invest_offers?utf8=blahblahblah").query
# => "utf8=blahblahblah"
Use URI::parse, URI::Generic#query:
require 'uri'
url = 'http://localhost:3000/en/invest_offers?utf8=blahblahblah'
URI.parse(url)
# => #<URI::HTTP:0x0000000213aae0 URL:http://localhost:3000/en/invest_offers?utf8=blahblahblah>
URI.parse(url).query
# => "utf8=blahblahblah"
Do the following:--
require 'uri'
url = 'http://localhost:3000/en/invest_offers?utf8=blahblahblah'
parsed_url = URI.parse(url)
if you just want to get string query part like "utf8=blahblahblah"
you should do
parsed_url.query
if you want get "blahblahblah",
you should just do
params["utf8"]
or else
p = CGI.parse(parsed_url.query)
# p is now {"utf8"=>["blahblahblah"]}
p["utf8"].first
#=> "blahblahblah"

I'm struggling with the following code:
I want a method to check if a string has content or not.
has_content = -> (a) { a!=nil && a.strip != ''}
c = ' '
has_content.call(c)
=> false
c.has_content
=> true
Why is the response different? Clearly I am lacking some Proc/lambdas knowledge.
I believe there is something missing in that code that is causing such behavior.
has_content is not defined for String, so unless you defined it before, it should raise an error
1.9.3p429 :002 > ''.has_content
NoMethodError: undefined method `has_content' for "":String
from (irb):2
from /Users/weppos/.rvm/rubies/ruby-1.9.3-p429/bin/irb:12:in `<main>'
As a side note, here's an alternative version of your code
has_content = ->(a) { !a.to_s.strip.empty? }
And here's an example
has_content.(nil)
# => false
has_content.('')
# => false
has_content.(' ')
# => false
has_content.('hello')
# => true
