How to extract data returned from array of hashes from API

Question

I wrote a small program to interact with the Indeed Ruby API.

I can print a single job title, but would like to loop through them all.

Here is the code:

require 'nokogiri'

require 'indeed-ruby'



client = Indeed::Client.new ("PUBLISHER_KEY_GOES_HERE")



params = {

  :q => 'python',

  :l => 'vancouver',

  :userip => '1.2.3.4',

  :useragent => 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_8_2)',

  :jobkeys => ["JOB_KEY_A", "JOB_KEY_B"] 

}



data = client.search(params)



# loop through all results and print the job title

data.each do |d|

  puts d["results"]["jobtitle"]

end

The

each

loop returns this error message:

i.rb:23:in `[]': no implicit conversion of String into Integer (TypeError)

from i.rb:23:in `block in <main>'

from i.rb:22:in `each'

from i.rb:22:in `<main>'

I assume this error message is saying it's trying to find an integer where I am putting a string in either

["results"]

or

["jobtitle"]

.

This line works, and prints a job title:

puts data["results"][0]["jobtitle"]

This implies I can access the 0th element of the results hash, and then access the jobtitle attribute.

I want to the loop to run like this and print 3 job titles:

puts data["results"][0]["jobtitle"]

puts data["results"][1]["jobtitle"]

puts data["results"][2]["jobtitle"]

I'm not sure how to put an

[i]

counter in the loop if it's expecting an integer.

Here is what the data looks like coming back from the Indeep API:

{"version"=>2,

 "query"=>"python",

 "location"=>"vancouver",

 "paginationPayload"=>"",

 "radius"=>25,

 "dupefilter"=>true,

 "highlight"=>true,

 "totalResults"=>483,

 "start"=>1,

 "end"=>10,

 "pageNumber"=>0,

 "results"=>

  [{"jobtitle"=>"Junior Software Developer",

    "company"=>"LaunchCode",

    "city"=>"Portland",

    "state"=>"OR",

    "country"=>"US",

    "formattedLocation"=>"Portland, OR",

    "source"=>"LaunchCode",

    "date"=>"Fri, 03 Feb 2017 04:10:27 GMT",

    "snippet"=>

     "Familiarity with an at least one imperative (Java, JavaScript,   PHP, C#, Objective-C, C/C++, <b>Python</b>, Ruby, etc.). Don’t have a CS   degree?...",

    "url"=>

     "http://www.indeed.com/viewjob?jk=9f75f0ea8825e3a8&qd=X0KuMlb--hp3Z0o2UU7dJOXoIlOcgm8VSZO61KKa0UOtGpLfFk1WY111OhfFWzZjMBRv9LrdGhB8olLNQGabmQRFit3-lRPP9j12GNvnf88&indpubnum=4334069173238194&atk=1b87s51b1a0kqb7s",

    "onmousedown"=>"indeed_clk(this,'782');",

    "jobkey"=>"9f75f0ea8825e3a8",

    "sponsored"=>false,

    "expired"=>false,

    "indeedApply"=>false,

    "formattedLocationFull"=>"Portland, OR",

    "formattedRelativeTime"=>"2 days ago",

    "stations"=>""},

It looks like the response from the Indeed API is a hash, but the value for the "results" key is an array inside the hash.

The response below from Ursus works:

This also worked:

for i in 1...10

   puts data["results"][i]["jobtitle"]

end

Here is the output:

Junior Software Developer

Data Scientist

Python Developer

Python Automation Developer - Hillsboro, OR

Computer Vision Engineer

Python Web Engineer

EMS Network Applications Engineer II

Software Engineer

Python Developer (full-stack)

Electrical Engineer, EMS Network Applications

Answer 1

So, data["results"] is an array. In ruby, you don't need an index to go through an array. You can do something like

[1, 2, 3].each do |i|
  puts i
end

In your case,

data["results"].each do |item|
  puts item["jobtitle"]
end
