How to convert string array into array and remove empty elements? - ruby-on-rails

I have a string '["", "abc", "", "def", "", "mno", "", "", "", "", ""]'. i want to convert it into array and remove empty values from that array. my desired output is abc;def;mno.
Can someone help me to do this?


You could use JSON.parse and select method:
str = '["", "abc", "", "def", "", "mno", "", "", "", "", ""]'
arr = JSON.parse(str).select(&:present?)
Output array: ["abc", "def", "mno"]
If you want to get abc;def;mno:
joined = arr.join(';')
Output string: "abc;def;mno"
Hope this helps


Use this code:
str = YAML.load('["", "abc", "", "def", "", "mno", "", "", "", "", ""]')
str.select{|a| a if a != ""}.join(";")


You can parse your string with JSON#parse and use delete with join:
str = '["", "abc", "", "def", "", "mno", "", "", "", "", ""]'
JSON.parse(str).tap { |arr| arr.delete('') }.join(';')
# => "abc;def;mno"

Accessing Data Members after using expand in Odata

I currently have an odata service with 2 entity sets. I am using expand to navigate to second entity set, and binding values from both in a table.
However, I am unable to bind data from second entity set as {to_PurchaseOrderItem/PurchaseOrderQuantityUnit}
Am I doing this wrong?
The JSON reply looks something like this, so I am really confused what I am doing wrong.

I am trying to access Order Quantity to be specific.

I think you are missing "results" while binding the control. Please see below and try
{to_PurchaseOrderItem/results/0/PurchaseOrderQuantityUnit}

How to send this type of parameter to server call in swift 3.0

I need to send this below parameters to a server in swift 3.0. How can I build the request parameters?
"step_1": [
{
"name": "",
"mobile": "",
"line_1": "",
"line_2": "",
"city": "",
"state": "",
"pincode": "",
"fax": "",
"gst": "",
"owner_name": "",
"dob": "",
"anniversary": ""
}
]

For upper json data below is Dictionary code:
let param = [["name": "abc",
"mobile": "123",
"line_1": "line_1",
"line_2": "line_2",
"city":"xyz",
"state":"abc",
"pincode":"000",
"fax":"123",
"gst":"gst",
"ownwer_name":"ownwer_name",
"dob":"xx-xx-xxxx",
"anniversary":"xx-xx-xxxx"]]
//Print data
print(param[0]["name"] as! String)

Hi I'm not sure if it will work, but anyway, try this
let params: ["step_1": [["name": "Some name",
"mobile": "12345678",
"line_1": "line_1 stuff",
"...": "..."]]]

Fetch odd position value from array

dddddddaniket
dddddddshivam
dddddddtiwari
dddddddaman
dddddddverma
dddddddpraneet
dddddddsodhi
The output I am getting after this is
ddddddd["title", "aniket", "month1", "200", "month2", "200", "month3", "200", "month4", "200", "month5", "200", "month6", "200", "month7", "", "month8", "", "month9", "", "month10", "", "month11", "", "month12", ""]

Now All I have to do is just ignore odd position values and store in a new array
Final output should be like this
[ "aniket", "200", "200", "200", "200", "200", "200", "", "", "", "", "", ""]
[ "shivam" "1" "2" "1", "", "2" "1", "", "", "", "", "", ""]
[ "tiwari", "1", "4", "2", "2", "2", "1", "", "", "", "", "", ""]
[ "aman", "2", "5", "3", "3", "3", "2", "", "", "", "", "", ""]
[ "verma", "3", "6", "4", "5", "3", "3", "", "", "", "", "", ""]
["praneet", "1", "1", "1", "8", "1", "6", "", "", "", "", "", ""]
["sodhi", "1", "", "1", "", "4", "", "", "", "", "", "", ""]
I am unable to do so Can anyone help me out with this???

This one works
bizs.select.with_index { |_, index| index.odd? }
irb output
bizs = ["title", "aniket", "month1", "200", "month2", "200", "month3", "200", "month4", "200", "month5", "200", "month6", "200", "month7", "", "month8", "", "month9", "", "month10", "", "month11", "", "month12", ""]
bizs.select.with_index { |_, index| index.odd? }
#=> ["aniket", "200", "200", "200", "200", "200", "200", "", "", "", "", "", ""]

result = []
array.each_with_index{|i,index| result << i if index.odd?}

Please find my proposed code as shown below,
even_items = []
odd_items = []
data.each_with_index do |bizs, index|
if index % 2 == 1
odd_items << bizs[index]
else
even_items << bizs[index]
end
end
This will result in two arrays one inserting all the elements with an odd index in odd_items array and the inserting all the even elements in the even_items array.

You are missing a : when declaring relationship type. On the last line, [HAS_ITEM] should be [:HAS_ITEM].

Add the header file in the server:
For example, if you are using PHP, add this:
header('Content-Type: application/json');
