  • Update "Properties" model when adding a new record in CakePHP

    - by Paul Willy
    Hi, I'm writing an application in CakePHP that, for now, is to be used to make quotes for customers. So Quote is a model. I want to have a separate model/table for something like "Property," which may be used by other models. Each time a user gets to the "Add Quote" action, I basically want to pull a Property called "nextQuoteNumber" or something along those lines, and then automatically increment that property, even if the new Quote isn't saved. So I don't think just using an autoincrement for Quote's id is appropriate here - also, the "quote number" could be different from the row's id. I know this is simple enough to do, but I'm trying to figure out the "proper" CakePHP way of doing it! I'm thinking that I should have a method inside the Property model, say "getProperty($property_name)", which would pull the value to return, and also increment the value... but I'm not sure what the best way of doing that is, or how to invoke this method from the Quotes controller. What should I do? Thanks in advance!

    I have a c# proyect that I need to change its product name upon compiling.

  • Are "proxy properties" good style?

    - by erlando
    I have a class with a string property that's actually several strings joined with a separator. I'm wondering if it is good form to have a proxy property like this: public string ActualProperty { get { return actualProperty; } set { actualProperty = value; } } public string[] IndividualStrings { get { return ActualProperty.Split(.....); } set { // join strings from array in propval .... ; ActualProperty = propval; } } Is there any risks I have overlooked?

  • Memory management technique for Objective-C iVars/properties

    - by David Rea
    Is the following code doing anything unnecessary? @interface MyClass { NSArray *myArray; } -(void)replaceArray:(NSArray *)newArray; @implementation MyClass -(void)replaceArray:(NSArray *)newArray { if( myArray ) { [myArray release]; myArray = nil; } myArray = [[NSArray alloc] initWithArray: newArray]; } @end What if I made the following changes: 1) Made myArray a property: @property (nonatomic, retain) NSArray myArray; 2) Changed the assignment to: self.myArray = [NSArray arrayWithArray: newArray]; Would that allow me to remove the conditional?

  • server control properties

    Okay i have a custom server control that has some autocomplete settings, i have this as follows and it works fine. /// <summary> /// Auto complete settings /// </summary> [System.ComponentModel.DesignerSerializationVisibility (System.ComponentModel.DesignerSerializationVisibility.Content), PersistenceMode(PersistenceMode.InnerProperty), Category("Data"), Description("Auto complete settings"), NotifyParentProperty(true)] public AutoCompleteLookupSettings AutoComplete { private set; get; } I also have a ParameterCollection that is really related to the auto complete settings, currently this collection resides off the control itself like so : /// <summary> /// Parameters for any data lookups /// </summary> [System.ComponentModel.DesignerSerializationVisibility(System.ComponentModel.DesignerSerializationVisibility.Content), PersistenceMode(PersistenceMode.InnerProperty)] public ParameterCollection Parameters { get; set; } What i would like to do is move the parameter collection inside of the AutoCompleteSettings as it really relates to my autocomplete, i have tried this but to no avail.. I would like to move from <cc1:TextField ID="TextField1" runat='server'> <AutoComplete MethodName="GetTest" TextField="Item1" TypeName ="AppFrameWork.Utils" /> <Parameters> <asp:ControlParameter ControlID="txtTest" PropertyName="Text" Name="test" /> </Parameters> </cc1:TextField> To <cc1:TextField ID="TextField1" runat='server'> <AutoComplete MethodName="GetTest" TextField="Item1" TypeName ="AppFrameWork.Utils" > <Parameters> <asp:ControlParameter ControlID="txtTest" PropertyName="Text" Name="test" /> </Parameters> </AutoComplete> </cc1:TextField>

  • Creating a function that will handle objects with common properties

    - by geocine
    Take this as an example I have trimmed this example for readability and you may not find the use of this concept here. class Teacher() { public Name {get; set;} public Salt {get; set;} public Department{get; set;} } class Student() { public Name {get; set;} public Salt {get; set;} public Section{get; set;} } public string GetEncryptedName(object Person) { //return encrypted name based on Name and Salt property return encrypt(object.Salt,object.Name) } callig the function GetEncryptedName(Teacher) GetEncryptedName(Student) How do you implement this kind of stuff?

  • Objective-C Objects Having Each Other as Properties

    - by mwt
    Let's say we have two objects. Furthermore, let's assume that they really have no reason to exist without each other. So we aren't too worried about re-usability. Is there anything wrong with them "knowing about" each other? Meaning, can each one have the other as a property? Is it OK to do something like this in a mythical third class: Foo *f = [[Foo alloc] init]; self.foo = f; [f release]; Bar *b = [[Bar alloc] init]; self.bar = b; [b release]; foo.bar = bar; bar.foo = foo; ...so that they can then call methods on each other? Instead of doing this, I'm usually using messaging, etc., but sometimes this seems like it might be a tidier solution. I hardly ever see it in example code (maybe never), so I've shied away from doing it. Can somebody set me straight on this? Thanks.

  • Autorelease and properties

    - by ganuke
    I have few questions to ask about the following class #import <Cocoa/Cocoa.h> @interface SomeObject { NSString *title; } @property (retain) NSString *title; @end implementation SomeObject @synthesize title; -(id)init { if (self=[super init]) { self.title=[NSString stringWithFormat:@"allyouneed"]; } return self; } -(void)testMethod{ self.title=[[NSString alloc] init] ; } -(void)dealloc { self.title=nil; [super dealloc]; } In the .h file do we need to declare the title and sub when we add the property. is it not enough to add the @property (retain) NSString *title; line. 2.Do i need to autorelease both assignment to title in the init and testMethod. if So why? Can some one explain these things to me.

  • C# properties: How are they instantiated?

    - by Pedery
    Hi! This might be a pretty straightforward question, but I'm trying to understand some of the internal workings of the compilation. Very simply put, imagine an arbitrary object being instantiated. This object is then allocated on the heap. The object has a property of type PointF (which is value type), with a get and a set method. Imagine the get and the set method containing a few calculations for doing their work. How and where (stack/heap) and when is this code instantiated? This is the background for this question: I'm writing get and set methods for an object and these methods need to be accessed very frequently. The get and set code in itself is rather massive so I feared that in a worst case scenario the methods would be instantiated as an object or a value type with all internal code for every access of the property. On the other hand the code is probably instantiated when the main object is created and the CPU is simply told to jmp to the property code start. Anyway, this is what I want to have clarified.

  • C# Using Reflection to Get a Generic Object's (and its Nested Objects) Properties

    - by Jimbo
    This is a scenario created to help understand what Im trying to achieve. I am trying to create a method that returns the specified property of a generic object e.g. public object getValue<TModel>(TModel item, string propertyName) where TModel : class{ PropertyInfo p = typeof(TModel).GetProperty(propertyName); return p.GetValue(item, null); } The code above works fine if you're looking for a property on the TModel item e.g. string customerName = getValue<Customer>(customer, "name"); However, if you want to find out what the customer's group's name is, it becomes a problem: e.g. string customerGroupName = getValue<Customer>(customer, "Group.name"); Hoping someone can give me some insight on this way out scenario - thanks.

  • Can't set up printing from Mac OS X (10.5.7) to an HP PSC 2410 shared from PC running Ubuntu 9.10

    - by Weston C
    I've got an HP PSC 2410 printer shared from a fresh Ubuntu 9.10 installation. I'm able to send documents to this printer over the network from another Ubuntu machine. But so far, I haven't been able to find a setup where I can send documents to that printer from a MacBook running 10.5.7. On the Mac side, when setting things up, I go into System Prefs Print & Fax, click on the "+" mark, select "IP", pick "IPP", enter the IP address of the Ubuntu box, leave the queue blank, enter the Name and location, and I think it's when I get to the "Print Using" (driver selection) part that I'm running into issues. If I use "Auto Select", it defaults to "Generic PostScript Printer", which I doubt the PSC 2410 is (and sure enough, if I print, the jobs don't go through). If I try "Select a driver to use...", there's not an option for an HP PSC 2400. This seems a little odd: I can plug the printer directly into one of our Macs and it immediately figures out the driver and I can print no problem, but that's apparently the way things work. So, that leaves one option: "Other", which, when selected, brings up a dialog apparently for the purpose of manually locating a driver. I've tried visiting HP's web site. They have drivers for earlier versions of Mac OS X, but state that after 10.4, Mac OS X should just come with the relevant drivers. I've also tried setting things up by interacting with the CUPS server on the Mac through a browser: I go to http://localhost:631/, select "Add New Printer", pick "Internet Printing Protocol (http)" for the Device selection, enter "http://ubuntu.machine.ip.address:631/printers/hp-psc-2400-series" for the Device URI, select "HP" for Make, and then on the next screen, we're back to the problem where the PSC 2400 just doesn't show up. There's an option to "provide a PPD file", which I assume would be the printer driver I can't find. A Google search for "HP PSC 2410 ppd Leopard" doesn't seem to yield much other than a reminder that the printer is supposed to just work out of the box on Leopard. A local search for ".ppd" or "2410" on either Mac also doesn't yield anything that looks like a relevant print driver. I'm totally stuck at this point. Any advice?

  • Dell All-in-One 810 CD software will no longer install

    - by authentictech
    I have a Dell All-in-One 810 printer from years ago and only recently installed it (a few months ago). Later I had reason to uninstall and re-install the printer but whenever I connect the printer Windows installs the printer drivers from its cache without the CD. How can I remove all traces of the drivers from the cache so that it will install only from the CD and not from the Windows driver cache?

  • How do I get a network printer installed in ubuntu 9.04?

    - by SoaperGEM
    My girlfriend's work computer now has Linux on one of the partitions, and for the most part it's running fine--except that I can't seem to get the network printers configured right. There are two of them: a Lanier MP 7500/LD275 and a Lanier MP C3000/LD430c, and Linux seems to have found them both automatically. I'll go through the steps of what I did, and what exactly went wrong. I went to Administration Printing, and clicked the new printer button. It searched for printers and found them both, listed under "Network Printers." I added them as new printers in succession. However, when I clicked "Print a Test Page," it failed saying there was a broken pipe. The device URIs were saved as socket://[ip address]:9100. I changed these to lpd://[ip address] per some online tutorial, which at first looked like it might have worked (but didn't). Then when I tried to print a test page, it first said Processing (and sometimes even Processing - printing test page, 4%, but always subsequently displays Idle - /usr/lib/cups/backend/lpd failed. Help! What do I do? It seems like Linux can find these printers just fine, and the drivers seem to be in place, so what's going wrong?

  • Recommendation for a simple no-frills Windows PDF printer driver?

    - by Scott Bussinger
    I'm looking for an extremely simple Windows PDF printer driver that I can recommend to clients. Ideally it would have these characteristics: When you print something, it should just create it as a temporary file and then display it in their default PDF viewer with no prompting. If they want to save it, they can save it manually from inside the viewer. This workflow should be with no special post-install configuration. Installation should be very simple. A double click the installation program and click "Finish" sort of thing. No complicated multi-step installation, no asking questions your grandmother wouldn't know the answer to (preferably no questions at all), no extra crap being installed. An option for a completely silent installation would be nice, but not necessary. Ideally it would be free to simplify their installing on a small network, but low cost is an option. I've tried a quite a few but none really fit the bill. Some can achieve the first goal but only after careful configuration, some try to install extra toolbars, some have other installation complexities that would make it hard for extremely novice users to succeed. Any suggestions? Thanks!

  • Canon MX870 printer only shows "Processing" on the status LCD

    I had my Canon MX870 installed perfectly fine in 11.10, but since upgrading to 12.04, it no longer works. The printer is recognized in print settings and when I attempt to print a test page, the printer LCD displays a "Processing" message, but then it disappears and nothing happens.

  • How do I get an Epson al-c 1700 printer working?

    - by Edmond Frants
    I have a brand new epson aculaser c1700 and i'd like to have it working fine on ubuntu 12.04. so i did my homework, kind of, no printer driver comes for this printer in cups ... so i asked epson support who drove me to avasys who no longer handle support since december 2011.

I tried to get ppd and filters from osx driver and use them to install the printer on ubuntu but no answer from printer and none printed sheet i have .... i'm so disappointed i could cry ... I'd like to work with someone to get this working fine, please help me!

  • WinForms prints to default printer even if it's not available/connected

    How can I determine if printer is connected? Typically this application prints to the default printer but in some cases that printer may not be available. If so I don't want the job sent to it's queue but rather printed to another available printer. I understand the PinterSettings.InstalledPrinters property. Does PrintDocument.PrinterSettings.IsValid return false if a printer is not available? Does WPF provide this kind of functionality?

  • Xerox Workcentre 3119 and Linux

    - by Milan Babuškov
    I'm trying to get Xerox Workcentre 3119 printer to work on Linux. It's a multifunction device (printer and scanner). I run the CUPS web interface at: http://localhost:631/ and it recognizes it on USB port and even suggests Gutenprint driver from the list. When I try to print a test page, the printer goes through "warming up" process (i.e. lights blink and sound is heard) but does not print anything. There are no errors in /var/log/cups/error_log and access_log shows as if everything is ok. The printer works fine in Windows XP. Does anyone have any experience with this printer on Linux?
