  • The Date type and the Android database

    - by cdonner
    I understand that SQLite stores dates as long integers. When I read rows into a cursor using the standard method (i.e. using the query() method that reads data into a cursor), the result is a date string that includes the time. If I want a different format, I have to parse the string back into a date - possible, but a bit backwards. By using a ViewBinder (as suggested in this question), I can pretty much do anything I want, but the date is already a string at the time the method executes. The accepted answer to the above question also suggests that storing dates as longs would help avoid this problem. I don't want to do that, just in case I want to interpret my data with something else than this application. Maybe I want to expose it via a provider. Is there a way to handle this in the database adapter instead, i.e. controlling the date format that the cursor contains, so that I don't have to change the schema, and don't have to parse the default output back into a Date type?

  • Formatting the date in unix to include suffix on day (st, nd, rd and th)

    - by skymook
    How can I add the suffix on the day number of a unix date? I'll explain. I have a TextMate bundle snippit that writes out today's date. It uses unix date and formatting. Here is the code: `date +%A` `date +%d` `date +%B` `date +%Y` It outputs: Monday 22 March 2010 I would like to add the suffix to the day (st, nd, rd and th) like so: Monday 22nd March 2010 As far as I can see, there is no native function in the unix date formatting, like there is in PHP (j). How would I achieve this in unix? A complicated regex on the day number?

  • Checking if date parsing is correct

    - by Javi
    Hello, I have this code for checking whether the Date is OK or not, but it's not ckecking all the cases. For example when text="03/13/2009" as this date doesn't exist in the format "dd/MM/yyyy" it parses the date as 03/01/2010. Is there any way to change this behaviour and getting an exception when I try to parse a Date which is not correct? What's the best way to do this validation? public static final String DATE_PATTERN = "dd/MM/yyyy"; public static boolean isDate(String text){ SimpleDateFormat formatter = new SimpleDateFormat(DATE_PATTERN); ParsePosition position = new ParsePosition(0); formatter.parse(text, position); if(position.getIndex() != text.length()){ return false; }else{ return true; } } Thanks.

  • MVC2 Model Binding Enumerables?

    - by blesh
    Okay, so I'm fairly new to model binding in MVC, really, and my question is this: If I have a model with an IEnumerable property, how do I use the HtmlHelper with that so I can submit to an Action that takes that model type. Model Example: public class FooModel { public IEnumerable<SubFoo> SubFoos { get; set; } } public class SubFoo { public string Omg { get; set; } public string Wee { get; set; } } View Snip: <%foreach(var subFoo in Model.SubFoo) { %> <label><%:subfoo.Omg %></label> <%=Html.TextBox("OH_NO_I'M_LOST") %> <%} %>

  • How to set default date in date_select helper in Rails

    - by brad
    I'm trying to set up a date of birth helper in my Rails app (2.3.5). At present it is like so. <%= f.date_select :date_of_birth, :start_year => Time.now.year - 110, :end_year => Time.now.year %> This generates a perfectly functional set of date fields that work just fine but.... They default to today's date which is not ideal for a date of birth field (I'm not sure what is but unless you're running a neonatal unit today's date seems less than ideal). I want it to read Jan 1 2010 instead (or 2011 or whatever year it happens to be). Using the :default option has proven unsuccessful. I've tried many possibilities including; <%= f.date_select :date_of_birth, :default => {:year => Time.now.year, :month => 'Jan', :day => 1}, :start_year => Time.now.year - 110, :end_year => Time.now.year %> and <%= f.date_select :date_of_birth, :default => Time.local(2010,'Jan',1), :start_year => Time.now.year - 110, :end_year => Time.now.year %> None of this changes the behaviour of the first example. Does the default option actually work as described? It seems that this should be a fairly straightforward thing to do. Ta.

  • Java Date vs Calendar

    - by Marty Pitt
    Could someone please advise the current "best practice" around Date and Calendar types. When writing new code, is it best to always favour Calendar over Date, or are there circumstances where Date is the more appropriate datatype?

  • Human readable and parsable date format in Java.

    - by Savvas Dalkitsis
    I want to save a Date object to a readable string (for example 22/10/2009 21:13:14) that is also parsable back to a Date object. I have tried many things and the best I could find was to use DateFormater for parsing and formating but it has a setback. When you format a date you lose seconds information. I tried to find if there is an option to format it and display the seconds (even better would be to the millisecond level since that's the resolution the Date object allows you to have) but I came up short. Any ideas?

  • Selecting Entity Data Model Laguage -- Visual C# source file generated even when i select VB

    - by Nickson
    Am adding an Entity Data Model to an ASP.NET website. When i Add New Item to the website and select ADO.NET Entity Data Model, am asked for the model name and language. I go a head and select Visual Basic as the language, the model is added and the site can compile with out any issues. however, the model it adds a ModelName.Designer.cs source file, instead of a ModelName.Designer.vb source file. am thinking this is strange as its happening with only one of my website. my other sites have .vb designer source file for their Entity Data Models. The site still compiles with out any errors but am afraid some thing is not right. any one experienced this?, is this normal behavior?

  • Determine if count of related model > 0

    - by Lowgain
    I have a model called Stem. I need a 'thumbs up' feature, so I have created a second model called Thumb, which consists of stem_id and user_id. I'm also using the restful authentication plugin for user credentials. I have the 'thumbs up' button working, which adds a row to the thumbs table fine, but I'd like to be able to check if the currently logged in user has already given a thumbs up to this particular stem. I tried adding this to the Stem model: def thumbed Thumb.count_by_sql ["SELECT COUNT(*) FROM thumbs WHERE user_id = ? AND stem_id = ?", current_user.id, self.id ] end The problem here is that the stem model has no access to the current_user variable the the controllers have. Is there a way I can get access to this property, or alternatively, is there another way I could go about checking this? I was hoping to get this as a property in the model because the stems are passed over to a Flex app using RubyAMF. Thanks!

  • How to edit and display Date in ASP.Net MVC 2

    - by Picflight
    I am storing a date in my database and want the user to be able to edit this date in the Edit View. In the past with ASP.Net web forms I have used 3 dropdownlists for the Month, Day and Year to get the date from the user and to bind it on display. I want to do the same in ASP.Net MVC and not sure how to do it? I am not using any jQuery or Javascript, the design calls for simple postback.

  • grails date from params in controller

    - by nils petersohn
    y is it so hard to extract the date from the view via the params in a grails controller? i don't want to extract the date by hand like this: instance.dateX = parseDate(params["dateX_value"])//parseDate is from my helper class i just want to use instance.properties = params you know :) in the model the type is java.util.Date and in the params is all the information (dateX_month, dateX_day, ...) i searched on the net and found nothing on this :( i hoped that grails 1.3.0 could help but still the same thing. i can't and will not belief that extracting the date by hand is nessesary!

  • Core Data data type for just the date - not including time

    - by Jason
    I am new at Core Data, and it seems like it is a great way to manage the data store. However I am also very memory-conscious due to the fact that the iPhone doesn't have that much of it. I was a little surprised to see that the data types are so limited - eg. there is a Date type which includes also the time, but no Date type for just the date! All the time information takes up precious bytes of memory, if I just wanted an attribute with the date (e.g. 2/15/2010 rather than 2/15/2010 02:34:48), how could I do this? Is it possible?

  • number of months between two dates - using boost's date

    - by MartinP
    I've used boost::gregorian::date a bit now. I can see that there are the related months & years & weeks duration types. I can see how to use known durations to advance a given date. Qu: But how can I get the difference between two dates in months (or years or weeks) ? I was hoping to find a function like: template<typename DURATION> DURATION date_diff<DURATION>(const date& d1,const date& d2); There would need to be some handling of rounding too.

  • convert variable with mixed date formats to one format in r

    - by jalapic
    A sample of my dataframe: date 1 25 February 1987 2 20 August 1974 3 9 October 1984 4 18 August 1992 5 19 September 1995 6 16-Oct-63 7 30-Sep-65 8 22 Jan 2008 9 13-11-1961 10 18 August 1987 11 15-Sep-70 12 5 October 1994 13 5 December 1984 14 03/23/87 15 30 August 1988 16 26-10-1993 17 22 August 1989 18 13-Sep-97 I have a large dataframe with a date variable that has multiple formats for dates. Most of the formats in the variable are shown above- there are a couple of very rare others too. The reason why there are multiple formats is that the data were pulled together from various websites that each used different formats. I have tried using straightforward conversions e.g. strftime(mydf$date,"%d/%m/%Y") but these sorts of conversion will not work if there are multiple formats. I don't want to resort to multiple gsub type editing. I was wondering if I am missing a more simple solution? Code for example: structure(list(date = structure(c(12L, 8L, 18L, 6L, 7L, 4L, 14L, 10L, 1L, 5L, 3L, 17L, 16L, 11L, 15L, 13L, 9L, 2L), .Label = c("13-11-1961", "13-Sep-97", "15-Sep-70", "16-Oct-63", "18 August 1987", "18 August 1992", "19 September 1995", "20 August 1974", "22 August 1989", "22 Jan 2008", "03/23/87", "25 February 1987", "26-10-1993", "30-Sep-65", "30 August 1988", "5 December 1984", "5 October 1994", "9 October 1984"), class = "factor")), .Names = "date", row.names = c(NA, -18L), class = "data.frame")

    Hi everyone, this is my question: I'm migrating data from a Btrieve file (.dat) through Pervasive Control Center and there is field type which is defined as integer but is a date and for example the date '31/12/2009' (seen in the legacy system) is view it as the number 733772 when I export it. The legacy system shows the date correctly but I can't export it in the same format or at least I can't convert it. Does anybody know how to convert this number through Excel or something?
