  • How do I do client-side form validation in jQuery?

    - by marcamillion
    I am trying to use this plugin: http://docs.jquery.com/Plugins/Validation Where #user_new is the id for my form, this is what my code looks like: $('#user_new').validate({ rules: { user[username]: "required", user[email]: { required: true, email: true } }, messages: { user[username]: "Please specify your name", user[email]: { required: "We need your email address to contact you", email: "Your email address must be in the format of [email protected]" } } }) Where these are how my input fields look when the page is rendered (generated by Rails): <input class="clearField curved" id="user_f_name" name="user[f_name]" size="30" type="text" value="First Name" /><br /> <input class="clearField curved" id="user_l_name" name="user[l_name]" size="30" type="text" value="Last Name" /><br /> <input class="clearField curved" id="user_username" name="user[username]" size="30" type="text" value="Username" /><br /> <input class="clearField curved" id="user_password" name="user[password]" size="30" type="password" value="Password" /><br /> <input class="clearField curved" id="user_password_confirmation" name="user[password_confirmation]" size="30" type="password" value="Password" /><br /> <input class="clearField curved" id="user_email" name="user[email]" size="30" type="text" value="Email Address" /><br /> I was just trying to validate username & email first. Then take it from there. For the life of me, I can't figure out how to specify the syntax and the rules for working with this plugin. Help!

  • How to combine multiple uiBinder-based widgets?

    - by jprusakova
    I need to insert a [number of] uiBinder-based widgets into another one, at a particular spot. The inserted widget has a somewhat complicated layout, so I am trying to define it in HTML. referencePanel.add(...) fails with NoSuchElement exception. reference.getElement().toSource returns "undefined". Any suggestions on how to do that? public class AppUIDemo extends Composite { @UiTemplate("AppUIDemo.ui.xml") interface AppUIDemoUiBinder extends UiBinder<Widget, AppUIDemo> { } @UiTemplate("ReferenceUI.ui.xml") interface ReferenceUIUiBinder extends UiBinder<Widget, ReferenceUI> { } private static AppUIDemoUiBinder uiBinder = GWT .create(AppUIDemoUiBinder.class); private static ReferenceUIUiBinder refUIBinder = GWT .create(ReferenceUIUiBinder.class); @UiField HTMLPanel referencePanel; public AppUIDemo() { initWidget(uiBinder.createAndBindUi(this)); ReferenceUI reference = new ReferenceUI(refUIBinder); referencePanel.add(reference, reference.getElement().getId()); } } public class ReferenceUI extends Composite { interface ReferenceUIUiBinder extends UiBinder<Widget,ReferenceUI> { } private static ReferenceUIUiBinder uiBinder = GWT .create(ReferenceUIUiBinder.class); public ReferenceUI() { initWidget(uiBinder.createAndBindUi(this)); } public CreditReferenceUI(final UiBinder<Widget, CreditReferenceUI> binder) { initWidget(binder.createAndBindUi(this)); } }

  • Is there a way to validates_presence_of only one time? (to skip that validation once the user's been

    - by GoodGets
    So, I'd like for a user to see an error message if he submits a comment and the :name is blank (typical error message, don't need help with that). However, I'd then like to allow the user to skip that validation once he's been notified that "we like all comments to have a name." So, he submits the comment once, sees the notification, then can submit the form again unchanged if he really doesn't want to add a name, and the validates_presences_of :name is skipped. But, I'm not sure how to go about doing this. I thought about checking to see where the request is coming from, but after a create, errors are handed off to the "new" action, which is the same as actual "new" comments. I then thought about checking to see if flash[errors] were present, but that won't work because there are other validations a comment has to pass. Finally, I thought about trying a validates_presences_of :name, :unless = :notified but wasn't sure how to define notified. I honestly hate asking such an open ended question, but wasn't sure where to get started. So, is there a way to just check a certain validation once?

  • Copying a subset of data to an empty database with the same schema

    - by user193655
    I would like to export part of a database full of data to an empty database. Both databases has the same schema. I want to maintain referential integrity. To simplify my cases it is like this: MainTable has the following fields: 1) MainID integer PK 2) Description varchar(50) 3) ForeignKey integer FK to MainID of SecondaryTable SecondaryTable has the following fields: 4) MainID integer PK (referenced by (3)) 5) AnotherDescription varchar(50) The goal I'm trying to accomplish is "export all records from MainTable using a WHERE condition", for example all records where MainID < 100. To do it manually I shuold first export all data from SecondaryTable contained in this select: select * from SecondaryTable ST outer join PrimaryTable PT on ST.MainID=PT.MainID then export the needed records from MainTable: select * from MainTable where MainID < 100. This is manual, ok. Of course my case is much much much omre complex, I have 200+ tables, so donig it manually is painful/impossible, I have many cascading FKs. Is there a way to force the copy of main table only "enforcing referntial integrity". so that my query is something like: select * from MainTable where MainID < 100 WITH "COPYING ALL FK sources" In this cases also the field (5) will be copied. ====================================================== Is there a syntax or a tool to do this? Table per table I'd like to insert conditions (like MainID <100 is only for MainTable, but I have also other tables).

  • Cannot call DLL import entry in C# from C++ project. EntryPointNotFoundException

    - by kriau
    I'm trying to call from C# a function in a custom DLL written in C++. However I'm getting the warning during code analysis and the error at runtime: Warning: CA1400 : Microsoft.Interoperability : Correct the declaration of 'SafeNativeMethods.SetHook()' so that it correctly points to an existing entry point in 'wi.dll'. The unmanaged entry point name currently linked to is SetHook. Error: System.EntryPointNotFoundException was unhandled. Unable to find an entry point named 'SetHook' in DLL 'wi.dll'. Both projects wi.dll and C# exe has been compiled in to the same DEBUG folder, both files reside here. There is only one file with the name wi.dll in the whole file system. C++ function definition looks like: #define WI_API __declspec(dllexport) bool WI_API SetHook(); I can see exported function using Dependency Walker: as decorated: bool SetHook(void) as undecorated: ?SetHook@@YA_NXZ C# DLL import looks like (I've defined these lines using CLRInsideOut from MSDN magazine): [DllImport("wi.dll", EntryPoint = "SetHook", CallingConvention = CallingConvention.Cdecl)] [return: MarshalAsAttribute(UnmanagedType.I1)] internal static extern bool SetHook(); I've tried without EntryPoint and CallingConvention definitions as well. Both projects are 32-bits, I'm using W7 64 bits, VS 2010 RC. I believe that I simply have overlooked something.... Thanks in advance.

  • Who likes #regions in Visual Studio?

    - by Nicholas
    Personally I can't stand region tags, but clearly they have wide spread appeal for organizing code, so I want to test the temperature of the water for other MS developer's take on this idea. My personal feeling is that any sort of silly trick to simplify code only acts to encourage terrible coding behavior, like lack of cohesion, unclear intention and poor or incomplete coding standards. One programmer told me that code regions helped encourage coding standards by making it clear where another programmer should put his or her contributions. But, to be blunt, this sounds like a load of horse manure to me. If you have a standard, it is the programmer's job to understand what that standard is... you should't need to define it in every single class file. And, nothing is more annoying than having all of your code collapsed when you open a file. I know that cntrl + M, L will open everything up, but then you have the hideous "hash region definition" open and closing lines to read. They're just irritating. My most stead fast coding philosophy is that all programmer should strive to create clear, concise and cohesive code. Region tags just serve to create noise and redundant intentions. Region tags would be moot in a well thought out and intentioned class. The only place they seem to make sense to me, is in automatically generated code, because you should never have to read that outside of personal curiosity.

  • How does the CheckBox obtain it's respective drawables?

    - by alex2k8
    The CheckBox class extends the CompoundButton, but add nothing to it. But some how it obtains it's respective look. I found some declarations in Android sources, but wonder how they are mapped to CheckBox class? public class CheckBox extends CompoundButton { public CheckBox(Context context) { this(context, null); } public CheckBox(Context context, AttributeSet attrs) { this(context, attrs, com.android.internal.R.attr.checkboxStyle); } public CheckBox(Context context, AttributeSet attrs, int defStyle) { super(context, attrs, defStyle); } } Styles <style name="Theme"> <item name="checkboxStyle">@android:style/Widget.CompoundButton.CheckBox</item> </style> <style name="Widget.CompoundButton.CheckBox"> <item name="android:background">@android:drawable/btn_check_label_background</item> <item name="android:button">@android:drawable/btn_check</item> </style> EDIT: Probably I was not clear... I understand how the drawable assigned to Widget.CompoundButton.CheckBox style, but how this style assigned to CheckBox class? I see the ".CheckBox" in the style name, but is this naming convention really what makes the trick? If so, what are the rules? If I derive MyCheckBox from CompoundButton, can I just define the Widget.CompoundButton.MyCheckBox style and it will work?

    I don't understand why this would give me a seg fault. Any ideas?

  • PostGreSQL - bind variables and date addition

    - by azp74
    I need to update some timestamp columns in a table in a PostGres (8.3) database. My query (simplified) look like this: update table1 set dateA = dateA + interval '10 hours' where id = 1234; This is part of a script and there's a lot to update so my preference is to use bind variables, rather than to have to build the query string each time. This means my query becomes: update table1 set dateA = dateA + interval '? hours' where id = ?; When I do this, the complaint is that I've supplied 2 bind variables when only one is required. If I try to put the ? outside the quote marks: update table1 set dateA = dateA + interval ? ' hours' where id = ?; I get: ... syntax error at or near "' hours'" It looks as though the query has been interpreted as ... dateA = dateA + interval '10' ' hours' ... I can't find anything in the documentation to help ... any suggestions? Thanks

  • How do I set an absolute include path in PHP?

    - by Nathan Long
    In HTML, I can find a file starting from the web server's root folder by beginning the filepath with "/". Like: /images/some_image.jpg I can put that path in any file in any subdirectory, and it will point to the right image. With PHP, I tried something similar: include("/includes/header.php"); ...but that doesn't work. I think that that this page is saying that I can set include_path once and after that, it will be assumed. But I don't quite get the syntax. Both examples start with a period, and it says: Using a . in the include path allows for relative includes as it means the current directory. Relative includes are exactly what I don't want. How do I make sure that all my includes point to the root/includes folder? (Bonus: what if I want to place that folder outside the public directory?) Clarification My development files are currently being served by XAMPP/Apache. Does that affect the absolute path? (I'm not sure yet what the production server will be.)

  • How to submit Nothing as a route value to ASP MVC

    - by Adam
    I have a route with several optional parameters. These are possible search terms in different fields. So, for example, if I have fields key, itemtype and text then I have in global.asax: routes.MapRoute( _ "Search", _ "Admin.aspx/Search/{Key}/{ItemType}/{Text}", _ New With {.controller = "Admin", .action = "Search" .Key = Nothing, .ItemType = Nothing, .Text = Nothing} _ ) My action takes optional parameters: Function Search(Optional ByVal Key As String = Nothing, _ Optional ByVal ItemType As Integer = 0, _ Optional ByVal Text As String = Nothing, _ Optional ByVal OtherText As String = Nothing) It then checks if the Key and Text strings have a non-null (and non-empty) value and adds search terms to the db request as needed. However, is it possible to send in a null value for, for example, Key but still send in a value for Text? If so, what does the URL look like? (Admin.aspx/Search//0/Foo doesn't work :) ) I know I can handle this using a parameter array instead, but wondered if this was possible using the sort of route described? I could of course define some other value as equivalent to null (for example, a space/%20) but is there any way to send a null value in the URL? I'm suspecting not, but thought I'd see if anyone knew of one. I'm using ASP MVC 2 for this project.

  • How do I mock a method with an open array parameter in PascalMock?

    - by Oliver Giesen
    I'm currently in the process of getting started with unit testing and mocking for good and I stumbled over the following method that I can't seem to fabricate a working mock implementation for: function GetInstance(const AIID: TGUID; out AInstance; const AArgs: array of const; const AContextID: TImplContextID = CID_DEFAULT): Boolean; (TImplContextID is just an alias for Integer) I thought it would have to look something like this: function TImplementationProviderMock.GetInstance( const AIID: TGUID; out AInstance; const AArgs: array of const; const AContextID: TImplContextID): Boolean; begin Result := AddCall('GetInstance') .WithParams([@AIID, AContextID]) .ReturnsOutParams([AInstance]) .ReturnValue; end; But the compiler complains about the .ReturnsOutParams([AInstance]) saying "Bad argument type in variable type array constructor.". Also I haven't found a way to specify the open array parameter AArgs at all. Also, is using the @-notation for the TGUID-typed parameter the right way to go? Is it possible to mock this method with the current version of PascalMock at all? Update: I now realize I got the purpose of ReturnsOutParams completely wrong: It's intended to be used for populating the values to be returned when defining the expectations rather than for mocking the call itself. I now think the correct syntax for mocking the out parameter would probably have to look more like this: function TImplementationProviderMock.GetInstance( const AIID: TGUID; out AInstance; const AArgs: array of const; const AContextID: TImplContextID): Boolean; var lCall: TMockMethod; begin lCall := AddCall('GetInstance').WithParams([@AIID, AContextID]); Pointer(AInstance) := lCall.OutParams[0]; Result := lCall.ReturnValue; end; The questions that remain are how to mock the open array parameter AArgs and whether passing the TGUID argument (i.e. a value type) by address will work out...

  • Setting up relations/mappings for a SQLAlchemy many-to-many database

    - by Brent Ramerth
    I'm new to SQLAlchemy and relational databases, and I'm trying to set up a model for an annotated lexicon. I want to support an arbitrary number of key-value annotations for the words which can be added or removed at runtime. Since there will be a lot of repetition in the names of the keys, I don't want to use this solution directly, although the code is similar. My design has word objects and property objects. The words and properties are stored in separate tables with a property_values table that links the two. Here's the code: from sqlalchemy import Column, Integer, String, Table, create_engine from sqlalchemy import MetaData, ForeignKey from sqlalchemy.orm import relation, mapper, sessionmaker from sqlalchemy.ext.declarative import declarative_base engine = create_engine('sqlite:///test.db', echo=True) meta = MetaData(bind=engine) property_values = Table('property_values', meta, Column('word_id', Integer, ForeignKey('words.id')), Column('property_id', Integer, ForeignKey('properties.id')), Column('value', String(20)) ) words = Table('words', meta, Column('id', Integer, primary_key=True), Column('name', String(20)), Column('freq', Integer) ) properties = Table('properties', meta, Column('id', Integer, primary_key=True), Column('name', String(20), nullable=False, unique=True) ) meta.create_all() class Word(object): def __init__(self, name, freq=1): self.name = name self.freq = freq class Property(object): def __init__(self, name): self.name = name mapper(Property, properties) Now I'd like to be able to do the following: Session = sessionmaker(bind=engine) s = Session() word = Word('foo', 42) word['bar'] = 'yes' # or word.bar = 'yes' ? s.add(word) s.commit() Ideally this should add 1|foo|42 to the words table, add 1|bar to the properties table, and add 1|1|yes to the property_values table. However, I don't have the right mappings and relations in place to make this happen. I get the sense from reading the documentation at http://www.sqlalchemy.org/docs/05/mappers.html#association-pattern that I want to use an association proxy or something of that sort here, but the syntax is unclear to me. I experimented with this: mapper(Word, words, properties={ 'properties': relation(Property, secondary=property_values) }) but this mapper only fills in the foreign key values, and I need to fill in the other value as well. Any assistance would be greatly appreciated.

  • Spider a Website and Return URLs Only

    - by Rob Wilkerson
    I'm not quite sure how best to define/articulate this, but I'm looking for a way to pseudo-spider a website. The key is that I don't actually want the content, but rather a simple list of URIs. I can get reasonably close to this idea with Wget using the --spider option, but when piping that output through a grep, I can't seem to find the right magic to make it work: wget --spider --force-html -r -l1 http://somesite.com | grep 'Saving to:' The grep filter seems to have absolutely no affect on the wget output. Have I got something wrong or is there another tool I should try that's more geared towards providing this kind of limited result set? Thanks. UPDATE So I just found out offline that, by default, wget writes to stderr. I missed that in the man pages (in fact, I still haven't found it if it's in there). Once I piped the return to stdout, I got closer to what I need: wget --spider --force-html -r -l1 http://somesite.com 2>&1 | grep 'Saving to:' I'd still be interested in other/better means for doing this kind of thing, if any exist.

  • How can I update a record using a correlated subquery?

    - by froadie
    I have a function that accepts one parameter and returns a table/resultset. I want to set a field in a table to the first result of that recordset, passing in one of the table's other fields as the parameter. If that's too complicated in words, the query looks something like this: UPDATE myTable SET myField = (SELECT TOP 1 myFunctionField FROM fn_doSomething(myOtherField) WHERE someCondition = 'something') WHERE someOtherCondition = 'somethingElse' In this example, myField and myOtherField are fields in myTable, and myFunctionField is a field return by fn_doSomething. This seems logical to me, but I'm getting the following strange error: 'myOtherField' is not a recognized OPTIMIZER LOCK HINTS option. Any idea what I'm doing wrong, and how I can accomplish this? *UPDATE: * Based on Anil Soman's answer, I realized that the function is expecting a string parameter and the field being passed is an integer. I'm not sure if this should be a problem as an explicit call to the function using an integer value works - e.g. fn_doSomething(12345) seems to automatically cast the number to an string. However, I tried to do an explicit cast: UPDATE myTable SET myField = (SELECT TOP 1 myFunctionField FROM fn_doSomething(CAST(myOtherField AS varchar(1000))) WHERE someCondition = 'something') WHERE someOtherCondition = 'somethingElse' Now I'm getting the following error: Line 5: Incorrect syntax near '('.

  • Creating a function in Postgresql that does not return composite values

    - by celenius
    I'm learning how to write functions in Postgresql. I've defined a function called _tmp_myfunction() which takes in an id and returns a table (I also define a table object type called _tmp_mytable) -- create object type to be returned CREATE TYPE _tmp_mytable AS ( id integer, cost double precision ); -- create function which returns query CREATE OR REPLACE FUNCTION _tmp_myfunction( id integer ) RETURNS SETOF _tmp_mytable AS $$ BEGIN RETURN QUERY SELECT id, cost FROM sales WHERE id = sales.id; END; $$ LANGUAGE plpgsql; This works fine when I use one id and call it using the following approach: SELECT * FROM _tmp_myfunction(402); What I would like to be able to do is to call it, but to use a column of values instead of just one value. However, if I use the following approach I end up with all values of the table in one column, separated by commas: -- call function using all values in a column SELECT _tmp_myfunction(t.id) FROM transactions as t; I understand that I can get the same result if I use SELECT _tmp_myfunction(402); instead of SELECT * FROM _tmp_myfunction(402); but I don't know how to construct my query in such a way that I can separate out the results.

E.g. : Below is the function on server side to modify users information. function modifyUser(username,userid) { //update query statements } Then jquery AJAX call will be like this : $.ajax({ url: 'users/modiyUser', success: function() { alert("Updation done") or any statements. } }); and I want to modify above i.e. server side function depending upon client input criteria. $.ajax({ function users/modiyUser(username,userid) { // I will write here any other statements which gives me some other output. } }); Above AJAX call syntax may not present, but i think you all understood what I am trying to do I simply wants to modify/override server side functions on client side. Please let me know is there any way to resolve above mentioned requirement. Thanks in adavance

  • RectangleGeometry with relative dimensions... how?

    - by Padu Merloti
    I'm trying to replicate the nowadays so fashionable "reflex" effect on a controltemplate for buttons I'm creating. The basic idea is to create a rectangle with a gradient fill from white to transparent and then clip some of that semi-transparent rectangle with a rectanglegeometry. The problem is that I don't know how to define a relative rectangle geometry. I kind of worked around width by defining a large value (1000), but height is a problem. For example, it works good for buttons that have a 200 height, but doesn't do anything for smaller buttons. Any ideas? <Rectangle RadiusX="5" RadiusY="5" StrokeThickness="1" Stroke="Transparent"> <Rectangle.Fill> <LinearGradientBrush StartPoint="0,0" EndPoint="0,0.55"> <GradientStop Color="#66ffffff" Offset="0.0" /> <GradientStop Color="Transparent" Offset="1.0" /> </LinearGradientBrush> </Rectangle.Fill> <Rectangle.Clip> <RectangleGeometry Rect="0,0,1000,60" /> </Rectangle.Clip> </Rectangle>

  • How does XAML set readonly CLR properties

    - by Igor Zevaka
    I am trying to create an application bar in code for WinPhone7. The XAML that does it goes like this: <PhoneApplicationPage.ApplicationBar> <shellns:ApplicationBar Visible="True" IsMenuEnabled="True"> <shellns:ApplicationBar.Buttons> <shellns:ApplicationBarIconButton IconUri="/images/appbar.feature.search.rest.png" /> </shellns:ApplicationBar.Buttons> </shellns:ApplicationBar> </PhoneApplicationPage.ApplicationBar> So I thought I'd just rewrite it in C#: var appbar = new ApplicationBar(); var buttons = new List<ApplicationBarIconButton>(); buttons.Add(new ApplicationBarIconButton(new Uri("image.png", UrlKind.Relative)); appbar.Buttons = buttons; //error CS0200: Property or indexer 'Microsoft.Phone.Shell.ApplicationBar.Buttons' cannot be assigned to -- it is read only The only problem is that Buttons property does not have a set accessor and is defined like so: public sealed class ApplicationBar { //...Rest of the ApplicationBar class from metadata public IList Buttons { get; } } How come this can be done in XAML and not C#? Is there a special way that the objects are constructed using this syntax? More importantly, how can I recreate this in code?

  • Magic function `bash ` not found

    - by inspectorG4dget
    I have a bunch of simulations that I want to run on a high-performance cluster, on which I should make reservations to get computing time. Since the reservations are bounded by time, I am developing an automation script that I can scp into the cluster and run. This script will then download the relevant simulation files, run them, and upload the results. Part of this automation script is in bash (cp, scp, etc) and the rest is in python. In order to develop this automation, I am using an IPython notebook. So far, I've coded all the python automation stuff in my IPython notebook and am trying to write the bash part of it now. However, it seems that the magic %%bash doesn't work in my IPython notebook. I get the following error when I have this code in my cell: Cell %%bash echo hi Error File "<ipython-input-22-62ec98e35224>", line 3 echo hi ^ SyntaxError: invalid syntax On a whim, I tried this: Cell %%bash print "hi" Error hi ERROR: Magic function `bash` not found. So I tried this with %%system, %%! and %%shell. But none of those work; they all give me the same error. Why is this happening? How can I fix this?
