I'm using the search function in geocoder, specifically the one for an IP address:
Geocoder.search("204.57.220.1")
When I type the command into the console and store the results as a variable I can view the contents:
[#<Geocoder::Result::Freegeoip:0x0000000241d848 #data={"ip"=>"204.57.220.1",
"country_code"=>"US", "country_name"=>"United States", "region_code"=>"WA",
"region_name"=>"Washington", "city"=>"Redmond", "zip_code"=>"98052",
"time_zone"=>"America/Los_Angeles", "latitude"=>47.674, "longitude"=>-122.122,
"metro_code"=>819}, #cache_hit=nil>]
but I can't figure out how to access the results. I've tried:
results.#data.zip_code, results[#data.zip_code], results[#data.results] and pretty much every other combonation I could think of. Any ideas?
Note that this returns an array. This means that you need to do something like:
results = Geocoder.search("204.57.220.1")
first_result = results.first
p first_result.data
p first_result.data['ip']
As Geocoder.search("204.57.220.1") is returning an array, you have to grab the first element of the array first, and then grab the data.
Do it this way:
results = Geocoder.search("204.57.220.1")
data = results.first.data
This will give you the data hash and from there you can extract your required data:
puts data['zip_code']
puts data['ip']

Ruby doesn't split \x1F instead it returns a triangle. The value is stored as ["118\u001F119"] and it should return ["118", "119"] when trying to access array.
When trying to print job_template_array[0]
Output:
job_template is 118▼119
Expected output:
job_template is 118
If I understand your question correctly, your array is something like job_template_array = ["118\u001F119", "120\u001F121"]. Of course the first value in the array (job_template_array[0]) will then be "118\u001F119". To get an array of ["118", "119"] you still need to split the string that's returned:
job_template_array = ["118\u001F119", "120\u001F121"]
first_item = job_template_array[0]
# "118\u001F119"
split_values = first_item.split("\x1F")
# ["118", "119"]
puts "job_template is #{split_values[0]}"
# job_template is 118
I've got a model that I need to group by the :sending_ip, which is a "cidr" column in the database.
#count_hash = Webhook.group('sending_ip').count
Resulting in this hash:
{#<IPAddr: IPv4:213.32.165.239/255.255.255.255>=>127000, #<IPAddr: IPv4:153.92.251.118/255.255.255.255>=>228000}
I cannot figure out how to reference this type of key. Below are some examples of the ways that I've tried to call these keys. All of them return nil or error.
#count_hash[#<IPAddr: IPv4:213.32.165.239/255.255.255.255>]
#count_hash["#<IPAddr: IPv4:213.32.165.239/255.255.255.255>"]
#count_hash[<IPAddr: IPv4:213.32.165.239/255.255.255.255>]
#count_hash["#<IPAddr: IPv4:213.32.165.239/255.255.255.255>"]
Elsewhere in my app, I've got a simpler example that works great. The other example groups by esp, which results in this hash:
{"hotmail"=>1000, "gmail"=>354000}
The second hash, I can refer to easily
#count_hash["gmail"]
To obtain the expected result of 354000
How can I achieve this same functionality with the previous hash that was grouped by sending_ip? Thank you in advance for your insight.
This:
#<IPAddr: IPv4:213.32.165.239/255.255.255.255>
is the result of calling #inspect on an instance of IPAddr. So the keys are IPAddr instances and you can say:
ip = IPAddr.new('213.32.165.239')
#count_hash[ip]
# 127000
Or you could iterate over the hash:
#count_hash.each { |ip, n| ... }
or over its keys:
#count_hash.keys.each { |ip| ... }
depending on what you need to do. You could even convert the keys to strings if that's more convenient:
#count_hash = #count_hash.transform_keys(&:to_s)
# or
#count_hash.transform_keys!(&:to_s)
I am sending a list of checkbox selected from PHP file to our Rails API server. All checked items' ID's will be sent in json format (campaign_ids in json_encode from PHP):
I got a URL being passed to our API like this
Started PUT "/campaigns/function.json?campaign_ids=["6","7"]&user_id=0090000007"
I need to get the campaign_ids ["6","7"] and process it like any other array using array.each do || end
How can I convert this to an array so I can use array.each?
The following sample code can achieve it but I think there could be a better way?
campaign_ids = params[:campaign_ids].to_s # [\"6\",\"7\"]
campaign_ids = campaign_ids.gsub(/[^0-9,]/,'') # 6,7
if campaign_ids.size.to_i > 0 # 3 ??
campaign_ids.split(",").each do |campaign_id|
...
end
end
The correct format of the URL should've been campaign_ids[]=6&campaign_ids[]=7. That would automatically yield an array of [6, 7] when you do params[:campaign_ids].
But assuming you can't change the format of the incorrect parameters, you can still get it via JSON.parse(params[:campaign_ids])
Try this
campaign_ids = JSON.parse(params[:campaign_ids])
You get params[:campaign_ids] as a string.
So, you will have to parse that json string to get array elements.
params[:campaign_ids] is already in your desired array format, you need not convert that to string using to_s.
You can do something like this
campaign_ids = params[:campaign_ids]
campaign_ids.each do |campaign_id|
# do the computation here
end
I have the following Array of hashes in a rails application:
a = ["{\"ROW1\"=>{\"correct\"=>{\"h\"=>\"10\", \"m\"=>\"11\", \"l\"=>
\"12\"}, \"wrong\"=>{\"h\"=>\"2\", \"m\"=>\"2\", \"l\"=>\"4\"}, \"blank
\"=>{\"h\"=>\"2\", \"m\"=>\"4\", \"l\"=>\"3\"}}, \"ROW2\"=>{\"correct
\"=>{\"h\"=>\"2\", \"m\"=>\"4\", \"l\"=>\"4\"}, \"wrong\"=>{\"h
\"=>\"4\", \"m\"=>\"6\", \"l\"=>\"6\"}, \"blank\"=>{\"h\"=>\"7\",
\"m\"=>\"5\", \"l\"=>\"6\"}}, \"ROW3\"=>{\"correct\"=>{\"h\"=>\"4\",
\"m\"=>\"6\", \"l\"=>\"7\"}, \"wrong\"=>{\"h\"=>\"6\", \"m\"=>\"7\",
\"l\"=>\"5\"}, \"blank\"=>{\"h\"=>\"7\", \"m\"=>\"9\", \"l\"=>
\"3\"}}}"]
I want to access its elements and create a database table from it, in the following format
ROW1 correct h=10, m=11,l=12
wrong h=2, m=2,l=4
blank h=2, m=4,l=3
...and similar for ROW2 and ROW3.
How can I do that?
I tried to access a value using
a["ROW1"]["Correct"]["h"]
...but it returns a nil value.
How to access the values of this array of hashes?
you need to first convert the string to hash which can be done as follows:
require 'json'
a = ["{\"ROW1\"=>{\"correct\"=>{\"h\"=>\"10\", \"m\"=>\"11\", \"l\"=>
\"12\"}, \"wrong\"=>{\"h\"=>\"2\", \"m\"=>\"2\", \"l\"=>\"4\"}, \"blank
\"=>{\"h\"=>\"2\", \"m\"=>\"4\", \"l\"=>\"3\"}}, \"ROW2\"=>{\"correct
\"=>{\"h\"=>\"2\", \"m\"=>\"4\", \"l\"=>\"4\"}, \"wrong\"=>{\"h
\"=>\"4\", \"m\"=>\"6\", \"l\"=>\"6\"}, \"blank\"=>{\"h\"=>\"7\",
\"m\"=>\"5\", \"l\"=>\"6\"}}, \"ROW3\"=>{\"correct\"=>{\"h\"=>\"4\",
\"m\"=>\"6\", \"l\"=>\"7\"}, \"wrong\"=>{\"h\"=>\"6\", \"m\"=>\"7\",
\"l\"=>\"5\"}, \"blank\"=>{\"h\"=>\"7\", \"m\"=>\"9\", \"l\"=>
\"3\"}}}"
]
hash_string = a[0]
hash = JSON.parse hash_string.gsub("\n", '').gsub('=>', ':')
# you access the hash now:
hash["ROW1"]["correct"]["h"]
# => 10
Btw, please note that there is a typo. Instead of Correct, the key is correct with small c instead of capital C.
Hope it helps : )
I have an array stored in a variable temp which looks like this:
temp.inspect output :
[#"Marlana Letelier", "completed_at"=>nil, "status"=>"incomplete", "name"=>nil, "lead_move_date"=>"2012-06-17 00:00:00", "archive_time"=>nil, "stop_time"=>nil, "priority"=>"2", "assigned_to_user_firstname"=>"Vanessa", "notes"=>"", "created_by_id"=>nil, "id"=>"804005", "assigned_to_id"=>"1", "dn_email_id"=>nil, "outcomes_string"=>"other", "lead_id"=>"101139", "flavor"=>"PhonecallTask", "stringified_parameters"=>"{\n'purpose' => 'continued contact attempt',\n'phone_number' => '361-946-9905',\n}", "created_at"=>"2011-12-21 13:29:07", "start_time"=>"2012-04-04 17:00:00"}>]
temp.class specifies it as an array but temp[1] doesn't output anything.
How do I access the elements ?
EDIT:
1) Temp either had nothing, 1 object or multiple objects
2) Check for nil
3) Get each object out
4) access the attributes
Although your inspect output looks wrong (I think you're missing some text that came out in <...> tags) it looks like you have an array with a single item. Verify this assumption by outputting temp.length.
Since Arrays in Ruby are 0-indexed, try temp[0] or temp.first.
