  • Saving a 'Date' using DataMapper on AppEngine+JRuby

    - by Ryan Montgomery
    I have a a model as follows: class Total include DataMapper::Resource property :id, Serial property :amount, Float, :default => 0.00 property :day, Date belongs_to :calendar end I am trying to select a specific Total from the data-store. class Calendar include DataMapper::Resource property :id, Serial property :name, String has n, :totals def get_total_for(date) return Total.first(:day => date, :calendar => self) end end When I call get_total_for(DateTime.now) I receive the following error on the call to the data-store. java.lang.IllegalArgumentException: day: org.jruby.RubyObject is not a supported property type. Is Date not allowed for usage in AppEngine? Is this a DataMapper issue? I have tried changing the name of the :day property to something else (hoping it was just a name conflict) but it doesn't seem to matter. Thanks for any help you can provide.

  • Context dependent validation

    - by Ole Lynge
    I would like to be able to validate an object in different contexts using DataAnnotations in .NET 4. For example: If I have a class with these annotated properties [Required] public string Name { get; set; } [Required] public string PhoneNumber { get; set; } [Required] public string Address { get; set; } I would like to be able to do something like bool namePhoneValid = Validator.TryValidateObject(entity, contextNamePhone, results1); bool allValid = Validator.TryValidateObject(entity, contextAll, results2); where contextNamePhone only validates Name and Phone, and contextAll validates all properties (Name, Phone and Address in this case). Is this possible? How should the validation context be constructed? Are there other/smarter ways to do this?

  • Dependent checkbox, do you think this can be simplified more?

    - by Louie Miranda
    I have the following code which is working, I was wondering if this can simplified more. Demo: http://jsfiddle.net/TnpNV/8/ <form name="cbform"> <input type="checkbox" value="1" name="one" id="one" /> one<br /> <input type="checkbox" value="1" name="two" id="two" /> two </form>? <script> $('#one, #two').click(function(event) { var checked = $(this).is(':checked'); if (checked) { $('#one').attr('checked', true); $('#two').attr('checked', true); } else { $('#one').attr('checked', false); $('#two').attr('checked', false); } }); </script> It's basically a two checkbox that is dependent on each other. Jquery was used to check and uncheck them. Regards

  • Fulltext and composite indexes and how they affect the query

    - by Brett
    Just say I had a query as below.. SELECT name,category,address,city,state FROM table WHERE MATCH(name,subcategory,category,tag1) AGAINST('education') AND city='Oakland' AND state='CA' LIMIT 0, 10; ..and I had a fulltext index as name,subcategory,category,tag1 and a composite index as city,state; is this good enough for this query? Just wondering if something extra is needed when mixing additional AND's when making use of the fulltext index with the MATCH/AGAINST. Edit: What I am trying to understand is, what happens with the additional columns that are within the query but are not indexed in the chosen index (the fulltext index), the above example being city and state. How does MySQL now find the matching rows for these since it can't use two indexes (or can it?) - so, basically, I'm trying to understand how MySQL goes about finding the data optimally for the columns NOT in the chosen fulltext index and if there is anything I can or should do to optimize the query.

  • animated text-shadow

    - by user1026090
    I have some keywords in the header of my website. Every few second I want one of them to glow up with the CSS text-shadow property. However, JQuery animation doesn't seem to support the CSS text-shadow property very well. http://jsfiddle.net/VWBsU/: This is kind of the result that I want, but the glow has to fade in and out. http://jsfiddle.net/VWBsU/1/ With a more common CSS-property, like color, the animation works perfectly, the red color kind of fades in. http://jsfiddle.net/VWBsU/2/ But the CSS text-shadow property doesn't even appear when trying to animate it. Does anyone know how to fade in and fade out a text-shadow property?

  • Text input for multi-valued attribute

    - by Sean
    I need to create an input form that will allow a user to enter any number of values for a particular attribute. I've tried several approaches, all of which seem to have various levels of failure. The latest model bean looks something like: public class Product { private String name; private String[] tags; ...accessors... } The input fields look something like: <h:inputText id="name" value="#{product.name}"></h:inputText> <h:inputText id="tag0" value="#{product.tag[0]}"></h:inputText> My plan was to allow the user is to use javascript to add additional form fields as needed. This type of setup gives me a 'Target Unreachable' error. What am I missing? I am using JSF 1.1 on WebSphere 6.1

  • Java equivalent for database schema changes like South for Django?

    - by gerdemb
    I've been working on a Django project using South to track and manage database schema changes. I'm starting a new Java project using Google Web Toolkit and wonder if there is an equivalent tool. For those who don't know, here's what South does: Automatically recognize changes to my Python database models (add/delete columns, tables etc.) Automatically create SQL statements to apply those changes to my database Track the applied schema migrations and apply them in order Allow data migrations using Python code. For example, splitting a name field into a first-name and last-name field using the Python split() function I haven't decided on my Java ORM yet, but Hibernate looks like the most popular. For me, the ability to easily make database schema changes will be an important factor.

  • Filter objects within two seconds of one another using SQLAlchemy

    - by Arrieta
    Hello: I have two tables with a column 'date'. One holds (name, date) and the other holds (date, p1, p2). Given a name, I want to use the date in table 1 to query p1 and p2 from table two; the match should happen if date in table one is within two seconds of date in table two. How can you accomplish this using SQLAlchemy? I've tried (unsuccessfully) to use the between operator and with a clause like: td = datetime.timedelta(seconds=2) q = session.query(table1, table2).filter(table1.name=='my_name').\ filter(between(table1.date, table2.date - td, table2.date + td)) Any thoughts?

  • Why do .png backgrounds appear black on iPhone device but not simulator?

    - by David Rea
    I started with a .tiff file and used GraphicConverter to change it to a .png and set a transparency color. Worked fine in the simulator but when I pushed to the device the transparency color became black. Tested with a .png I downloaded from the net and that worked fine, so it seems to only happen with some files. Thus I suspect it has something to do with the way GraphicConverter writes the .pngs, but I don't know enough about file formats to debug it. Any ideas/suggestions? Ideally I'd like to programatically treat all .pngs because my app allowed dynamic loading of arbitrary files, so I can't verify the transparency beforehand.
