I have to add a value in center of first row in csv using CSV.generate
I think it is not possible as CSV is just a comma separated file and does not contain any data about styling. Alternatively, you can add an empty column(s) (commas) to mimic this behavior.
This is a strange request since .CSV is not a presentation layer. Formatted values are not typically stored in .CSV but I suppose there's no reason they can't be.
The Ruby method center should help.
"hello".center(20) #=> " hello "
Then just put the centered value into you .CSV.

I want to get the value of col B for the most recent date. The number of rows may change... i.e. oct isnt always the most recent date.
On dates u can use the MAX function. If you wrap this inside a VLOOKUP the MAX will get you the searchkey and the returns the value next to it.
=VLOOKUP(MAX(A1:A10),A1:B10,2,0)
With data in cols A and B, use:
=index(B:B,match(max(A:A),A:A,0))
As you see from the example, we don't even have to sort the data.
proper way:
=MAXIFS(B:B, A:A, MAX(A:A)
or:
=FILTER(B:B, A:A=MAX(A:A))

On Sheet2 I am wanting to show all the columns associated with a specific string that comes from a dropdown data validation. I have tried using VLOOKUP but that only outputs the first entry found, I want to print every entry along the row.
I put an example of what I am trying to get it to look like but not sure if VLOOKUP or QUERY or FILTER or something else is what I need
In your example spreadsheet, sheet 2, delete everything in the range F3:I and then enter in F3
=query(A:D, "where D='"&F2&"'",1)
If you want to reference the data on the sheet you'll have to use
=query('Draft Board'!A:D, "where D='"&F2&"'",1)
See if that works ?

I'm trying to run a for loop and every time a loop runs through a UIButton is allocated and initialized. The issue is that all of these buttons need different names. Is there a way to name the button based on the value of the integer in the for loop?
Is sounds like you want to put the buttons in an NSArray. Items in the array can be referenced by an index into the array.

Sorry for my English. I have a model with some field.
How to add a number to a current value in field?
I want to add the number several times
i generated scaffold.I use this to create modal. But i want to add number to a current value when i clicked submit
#foo = Foo.first
#foo.bar += 10
#which is a shorter way of saying #foo.bar = #foo.bar + 10
#foo.save
If this isn't helpful, please add some more details to your question, eg your example code you have so far.

I have a simple search query that returns list of buildings based zip codes. The zip codes are stored in address table with a one to one relation on buildings and address. Now I need to search the buildings based on multiple zip codes.
<input type="text"
name ="fs_Zip[]"
class="input-small text-tip"
data-original-title="Enter Zip Code to search."
placeholder ="Zip Code"/>
this is the code in my view. and in controller
buildings = buildings.where('address.zip in (?)', params['fs_Zip'])
if (!params["fs_Zip"].blank? && params["fs_Zip"] != 'zipcode')
But it does not give desired result. Any help.
If I understand correctly, your query should look something more like this:
buildings = Building.joins(:address).where('addresses.zip in (?)', params['fs_Zip'])
But you need to make sure params['fs_Zip'] is in the proper format for that query (i.e. an array of zips).
