Ruby on Rails retrieve datetime by converting it from UTC to user's time zone from database by querying date


If you store the datetime you can use it for that query using beginning_of_day and end_of_day methods on the time with timezone

date = Time.parse('Wed, 19 Nov 2014
19:23:59 UTC +00:00')
# => 2014-11-19 19:23:59 UTC
d = date.in_time_zone('Paris')
# => Wed, 19 Nov 2014 20:23:59 CET +01:00


User.where(created_at:
(d.beginning_of_day..d.end_of_day)).count
#   (46.5ms)  SELECT COUNT(*) FROM "users"  WHERE
("users"."created_at" BETWEEN '2014-11-18
23:00:00.000000' AND '2014-11-19 22:59:59.999999')

Trying to retrieve data from database then pass to html in Rails's view
I'm just trying to answer this question because when I started out with Rails no one helped me. Everyone just said google it. All the examples where good but I wasn't able to figure the stuff out and connect the important things. Your Rails app is most likely a RESTful application. That means let's say you got a products_controller.rb. Then you could access them like so: # all products /product

Trouble converting VARCHAR to DATETIME in SQL (with timezone)
Since it's a string with a timezone in it, you need to convert it to a DATETIMEOFFSET type: SELECT CONVERT(DATETIMEOFFSET, '2014-07-14T10:00:00.000-08:00', 127) (No column name) ---------------------------------- 2014-07-14 10:00:00.0000000 -08:00 This works just fine. Once you have that, you can then convert it to a local DATETIME as needed, e.g. with DECLARE @DateTimeOffset DATETIMEOFFSET

Using DateTime to get the GetLastWriteTime of a file, from any cultural format, and then converting it to yyyy/MM/dd
It would have been better if you could pass DateTime object to your EXE, but it seems you want to pass Dates as string to your exe and that too in particular format of yyyy/MM/dd. Use: stopDate.Text = fileDate.ToString("yyyy/MM/dd", CultureInfo.InvariantCulture); This will always give you a date string in same format irrespective of culture. Use the same for other date: startDate.Text = fiveDa

Wrong datetime is stored in database
I'm not familiar with mysqli (I actually use PDO) but maybe you should verify if your database has default values for you date fields. Also, if I'm not wrong, you shoud use double quotes in your query. Finally, you should take care about SQL Injection (wikipedia.org/wiki/SQL_injection). You're query may be vulnerable.
