ruby - Using random key/value from YAML file -

-

i'm trying use random key, value pair yaml file looks this:

'user_agents':   'mozilla': '5.0 (compatible; googlebot/2.1; +http://www.google.com/bot.html)'   'mozilla': '5.0 (compatible; yahoo! slurp; http://help.yahoo.com/help/us/ysearch/slurp)'   'mozilla': '5.0 (iphone; u; cpu iphone os 3_0 mac os x; en-us) applewebkit/528.18 (khtml, gecko) version/4.0 mobile/7a341 safari/528.16'   'mozilla': '4.0 (compatible; msie 6.0; windows nt 5.1)'

using script:

require 'mechanize' require 'yaml'  info = yaml.load_file('test-rand.yml') @user_agent = info['user_agents'][info.keys.sample]  agent = mechanize.new agent.user_agent = @user_agent if @user_agent.nil?   puts "the user agent nil" else   puts "using: #{@user_agent}" end

however while running script keep getting the user agent nil, how pull random key/value yaml file?

i've tried @user_agent = info['user_agents'][info[rand(values.size)]]

i think figured out solution this, if has better 1 please let me know, changed yaml file have 1 mozilla multiple values:

yaml:

'user_agents':   'mozilla': ['5.0 (compatible; googlebot/2.1; +http://www.google.com/bot.html)', '4.0 (compatible; msie 6.0; windows nt 5.1)', '5.0 (iphone; u; cpu iphone os 3_0 mac os x; en-us) applewebkit/528.18 (khtml, gecko) version/4.0 mobile/7a341 safari/528.16', '5.0 (compatible; yahoo! slurp; http://help.yahoo.com/help/us/ysearch/slurp)']

i took keys , value , broke down yaml file key value pair using this:

info = yaml.load_file('test-rand.yml') info['user_agents'].each |k,v|

from there turned value array, sampled array, , saved result variable, created new hash called @user_agent , gave key of k , value of arr_val.to_s:

arr_val = v.to_a.sample @user_agent = {k => arr_val.to_s}

full script:

require 'mechanize' require 'yaml'  info = yaml.load_file('test-rand.yml') info['user_agents'].each |k,v|   arr_val = v.to_a.sample   @user_agent = {k => arr_val.to_s} end  agent = mechanize.new agent.user_agent = @user_agent if @user_agent.nil?   puts "the user agent nil" else   puts "using: #{@user_agent}" end #<= using: {"mozilla"=>"5.0 (iphone; u; cpu iphone os 3_0 mac os x; en-us) applewebkit/528.18 (khtml, gecko) version/4.0 mobile/7a341 safari/528.16"} #<= using: {"mozilla"=>"5.0 (compatible; googlebot/2.1; +http://www.google.com/bot.html)"} #<= using: {"mozilla"=>"4.0 (compatible; msie 6.0; windows nt 5.1)"}

asp.net mvc - breakpoint on javascript in CSHTML? -

-
i have .cshtml file has javascript tag. within script tag have few lines of javascript. first line of javascript refers property in @viewbag. other javascript lines plain script without mvc related references. observation: can place breakpoints (visual studio 2015) on each of these javascript lines. however, breakpoints has white dot in center of breakpoint symbol (red circle) except line @viewbag reference (this particular line not have white dot in center). it seems breakpoint without white dot hit during run-time. question: can explain going on here? white dot mean? why plain red breakpoint line line hitting breakpoint? the visual studio debugger expecting debug actual server-side code within .cshtml file opposed client-side javascript within it. iirc, visual studio allow debug javascript code expected in internet explorer (and possibly edge), other browsers want use either third-party tool or developer tools (f12) within browser. an easy approach take advant...
