• Problem getting value from "Checkbox group value prompt"

  - by Veer

  Hi, I've value prompt with ui:checkbox group parameter: p_IsLastMonth Name: Prompt_IsLastMonth ItemCount: 1; UseValue:Yes, DisplayValue: LastMonth? and two Date Prompts. Whenever the checkbox is checked, the UseValue 'Yes' is passed to the parameter 'p_IsLastMonth'. But whenever the checkbox is left as it is, it results in an error. Element 'selectOptions' is not valid for content model: 'All(style,defaultSelections,conditionalStyles,conditionalRender,XMLAttributes)' I also tried giving a default value. But the default value has to be in the collection. But i want only one checkbox to be displayed. I tried with html checkbox. But i'm not able to send the value 'either yes or no' to the parameter through javascript because however the finish button overrides the value. Any help?

• Passing parameters into ViewModels (Prism)

  - by vXtreme

  Hi I can't figure out how to pass parameters to my viewmodels from other views or viewmodels. For instance, I have a View called Customers. There is a grid inside, and if you double-click the grid, a new view is supposed to come up and allow you to edit that customer's data. But how will the View(Model) responsible for editing data know which customer it's supposed to open if I can't pass any parameters inside? EventAggregator is out of the question because I obviously can't create hundreds of eventargs, each for one view. And besides, it's a lousy solution. So far I was able to come up with: CustomerDataView custView = new CustomerDataView(customerId, currentContext); manager.Regions[RegionNames.Sidebar].AddAndActivate(custView); What do you think about this particular solution? Is this the way it's normally done? What I don't like about this is the fact that I lose out on automatic dependency injection by Unity.

• change the return of to_param by action? or, terribly broken edit action if perma-url is returned in

  - by Stacia

  I did some stuff to have to_param return a perma-url so I'd have seo friendly links. Upon creation and update it will generate and return the perma-url in a to_param method that I put in the model. However this causing me some grief in other areas. I have a form that looks like this: <% @apps.each do |app| %> <% fields_for "[id][]", app do |fields| %> .... this fails terribly since it tries to insert the perma-url in place of the id. If I could just restrict to_param by action, that could solve things. If I change app to app.id, that fails since I have stuff like this: fields.check_box :is_featured . I suppose I could get the app instance, but that feels hacky. Again please excuse my lack of rails-foo ;)

• Python: Data Object or class

  - by arg20

  I enjoy all the python libraries for scraping websites and I am experimenting with BeautifulSoup and IMDB just for fun. As I come from Java, I have some Java-practices incorporated into my programming styles. I am trying to get the info of a certain movie, I can either create a Movie class or just use a dictionary with keys for the attributes. My question is, should I just use dictionaries when a class will only contain data and perhaps almost no behaviour? In other languages creating a type will help you enforce certain restrictions and because of type checks the IDE will help you program, this is not always the case in python, so what should I do? Should I resort to creating a class only when there's both, behaviour and data? Or create a movie class even though it'll probably be just a data container? This all depends on your model, in this particular case either one is fine but I'm wondering about what's a good practice.

• How to always return a set number of records when using find_related_tags with acts-as-taggable-on

  - by hadees

  I'm using the acts-as-taggable-on gem and I need to use find_related_tags on my survey model to get back 3 surveys every time. In the event there aren't always 3 related I need to pick how ever many are related plus some random ones to get to 3. Additionally I have a method I wrote called completed_survey_ids which return an array of survey_ids that shouldn't be used because the user has already completed them. Also there is a rare case that there won't be enough surveys because the user has completed them all so in that event it is okay to return less surveys then requested. I did write a named_scope to handle getting rid of the completed_survey_ids that I think works named_scope :not, lambda { |survey_ids| {:conditions => "id NOT IN (#{survey_ids.join(',')})" } }

• Core Data Predicate To Many

  - by Vikings

  I have a core data model that has a one to many relationship, there is a category, and it can contain many subcategories. Category <---- Subcategory I am trying to perform a fetch that checks if a particular Category contains a Subcategory with a particular name. Let's say I have two categories below, I want to fetch to see if there are any subcategories name "Apple" in the Category named "Fruits". Vetegables - Carrot - Lettuce Fruits - Apple - Orange - Pear Code: - (SubCategory *)searchForSubCategoryWithName:(NSString *)subCategory inCategory:(Category *)category { NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] init]; NSEntityDescription *entity = [NSEntityDescription entityForName:@"SubCategory" inManagedObjectContext:self.beer.managedObjectContext]; [fetchRequest setEntity:entity]; NSPredicate *predicate = [NSPredicate predicateWithFormat:@"name == [c] %@", subCategory]; [fetchRequest setPredicate:predicate]; NSError *error; NSArray *fetchedObjects = [self.beer.managedObjectContext executeFetchRequest:fetchRequest error:&error]; if (fetchedObjects != nil && fetchedObjects.count > 0) { return [fetchedObjects objectAtIndex:0]; } else { return nil; } }

• Django: switch language of message sent from admin panel

  - by yoshi

  I have a model, Order, that has an action in the admin panel that lets an admin send information about the order to certain persons listed that order. Each person has language set and that is the language the message is supposed to be sent in. A short version of what I'm using: from django.utils.translation import ugettext as _ from django.core.mail import EmailMessage lang = method_that_gets_customer_language() body = _("Dear mister X, here is the information you requested\n") body += some_order_information subject = _("Order information") email = EmailMessage(subject, body, '[email protected]', ['[email protected]']) email.send() The customer information about the language he uses is available in lang. The default language is en-us, the translations are in french (fr) and german (de). Is there a way to use the translation for the language specified in lang for body and subject then switch back to en-us? For example: lang is 'de'. The subject and body should get the strings specified in the 'de' translation files.

• Is there a .NET BCL class to help with hand-rolled property path binding?

  - by Wayne

  WPF and Silverlight have a data binding model whereby I can provide a Binding with a Path which comprises a dot-notation of property accessors down from a DataContext to a specific value inside a complex object graph (eg. MyDataContext.RootProperty.SubProperty.Thing.Value) I have a (non-UI) requirement to accept such a path expressed as a simple string, and to use reflection on an object which is (hopefully) of a type which exposes the right property getters and setters in order to read and/or write values to those properties. Before I go off and start writing the parser and reflection code, is there a handy Framework 3.5 BCL class to help with this?

• WPF combo box, adding an all options item, when binding to an Observable Collection

  - by Joel Barsotti

  So I've got an object that has an observable collection. Most places I bind to this collection I only want the user to select a single item. But in one place I want the combobox to include an all items option. Is the way to do this simply with xaml converter? It seems like doing it in the view model would be a good idea, but it's really a lot dependency object goop to basically wire up an collection that is two objects deep for an on change event, where as the xaml converter just works. But I always feel like xaml converters should be generic and reusable, where in this instance, the xaml converter would be more of a one off. Of course the third option would be to create one off list for UI in the object that contains the standard observable collection. But this seems to be mixing the logic and presentation in a way that makes me uncomfortable.

• Paperclip + ImageMagick on Windows 7: Image display fails when I add styles to attached_file in mode

  - by Brian Roisentul

  I'm working with Ruby on rails 2.3.8, NetBeans IDE. I've installed paperclip and I could show/save images successfully. Now, I've installed ImageMagick-6.6.2-4-Q16(for windows 7, 64bits). Until that moment, my model looked like this(and worked fine): has_attached_file :photo Now, after installing ImageMagick, when I add the :style line it fails: has_attached_file :photo, :styles => {:thumb => "100x100#", :small => "150x150>", :large => "400x400>" } and it throws the following error message when I try to upload an image: TypeError in ProfilesController#update backtrace must be Array of String The only thing I'm doing in the update action of that controller is the following: @profile.update_attributes(params[:profile]) @profile.update_attribute(:photo, params[:profile][:photo]) I've also installed miniMagick gem(because I read somewhere I had to do it). What am I missing?

• CakePHP save without form

  - by SDwebs

  I have a photo gallery I'm trying to set a picture as the cover for the album. I have a field cover_id in the albums table that has already been linked to the photos through the model. I'm passing the album_id and photo_id to the controller. I want to update the album.cover_id passed thru the params with the photo_id passed thru the params. Is there a way to do this or a way to make the link a form without having it look like or form or changing much of the CSS?

• How to handle customers with multiple addresses in CakePHP

  - by Ryan

  I'm putting together a system to track customer orders. Each order will have three addresses; a Main contact address, a billing address and a shipping address. I do not want to have columns in my orders table for the three addresses, I'd like to reference them from a separate table and have some way to enumerate the entry so I can determine if the addressing is main, shipping or billing. Does it make sense to create a column in the address table for AddressType and enumerate that or create another table - AddressTypes - that defines the address enumeration and link to that table? I have found other questions that touch on this topic and that is where I've taken my model. The problem I'm having is taking that into the cakePHP convention. I've been struggling to internalize the direction OneToMany relationships are formed - the way the documentation states feels backwards to me. Any help would be appreciated, Thanks!

• How can I prevent application domain stealing?

  - by dr jerry

  I'm in the process of making a javascript application and I want to bring that online, lets call it mydesign. I'm living in the Netherlands so mydesign.nl can be mine. Now is mydesign.com available for sale by some domain broker sales bastards. And those bastards don't accept a first bid lower than 1000$ which is a about ten times of the budget I'm willing to pay. So far so good, it's a sick business model but it's there. Now lets imagine that mydesign.nl is a huge success in the Netherlands and I'm makin tons of profits out of advertisements and other things I'm not yet aware of (I know entering the lotery gives a better chance of earning money, but lets just imagine). Is there a way (licence, legal or otherwise) to prevent the sick owners of mydesign.com to download and steal my javascript app and deploy it on their own site and take the profits of my app?

• pyramid - How to handle complex URL in a elegant way?

  - by Lingfeng Xiong

  I'm writing a admin website which control several websites with same program and database schema but different content. The URL I designed like this: http://example.com/site A list of all sites which under control http://example.com/site/{id} A brief overview of select site with ID id http://example.com/site/{id}/user User list of target site http://example.com/site/{id}/item A list of items sold on target site http://example.com/site/{id}/item/{iid} Item detailed information # ...... something similar As you can see, nearly all URL are need the site_id. And in almost all views, I have to do some common jobs like query Site model against database with the site_id. Also, I have to pass site_id whenever I invoke request.route_path. So... is there anyway for me to make my life easier? Thanks in advance.

• Replacing TCP/IP pipe with WCF

  - by msarchet

  So currently my company is using a TCP/IP connection to talk between server and client programs, right now we are building this connection using System.RunTime.Remoting, which is clunky and not that reliable. It was built about 5 years ago and the model keeps getting reused and it's starting to propagate some issues, ports used, refused connections, etc. I'm trying to find some resources on how to change this over to WCF but I'm not really sure what I am looking for or what I should be searching. If you want some more information on what were actually doing with it I can go into some detail, but I'll need to pull up the code and make sure I explain it completely. thanks!

• Can I get Androis OS?

  - by Michael Turner

  I bought a umpc on ebay, A Ipad touchscreen like device. I had been looking at a particular hardware model that many sellers had, on which was running Android (1.6). I based my choice on the one that offered "free" shipping via UPS (3-5 day) delivery. after the purchase I noticed that the one I bought has Windows CE, not android (!#$^%!!!). Now I want to know if I can get a copy of Android 1.6 or higher and put it on this device. I have looked on google, Torrent sites and ebay, but cannot find a copy of Android OS

• Spring Roo and aspect-oriented programming

  - by marcos

  Hello, i've been running some experiments of my own with Spring Roo and it seems to be pretty cool, but i noticed that this tool makes heavy use of AOP on the model layer. I'm thinking about creating a real project using Roo and what i would like to know is: Why AOP is everywhere? Is That ok? What are advantages and disadvantages of this approach? I'm quite new to aspect-oriented programming and some guidance would be greatly appreciated. Thanks in advance!

• Drools rules import with wildcard

  - by ZeKoU

  Hello everyone, I am working with Drools rules. Some developers have created rules which I have to put on Guvnor (rules repository) and build packages. In these rules they have import statements with wildcards, for example: import org.drools.runtime.rule.*; When I upload this on Guvnor and try to build, it tells me: Unable to introspect model for wild card imports (org.drools.runtime.rule.*). Please explicitly import each fact type you require. Is it possible to use wildcard imports in Drools rules???

• Database Error django

  - by Megan

  DatabaseError at /admin/delmarva/event/ no such column: delmarva_event.eventdate I created a class in my models.py file: from django.db import models from django.contrib.auth.models import User class Event(models.Model): eventname = models.CharField(max_length = 100) eventdate = models.DateField() eventtime = models.TimeField() address = models.CharField(max_length = 200) user = models.ForeignKey(User) def __unicode__(self): return self.eventname and now when i try to view my events in my admin or my main_page it gives me the error that there is no eventdate. I tried syncing the db again but nothing changed. Also, I hashtagged eventdate out to see if I get a different error and then it states that delmarva_event.eventtime does not exist as well. I It is weird because it does not have a problem with eventname. Any suggestions would be greatly appreciated!

• API to determine whether running on iPhone or iPad

  - by Eric

  Is there an API for checking at runtime whether you are running on an iPhone or an iPad? One way I can think of would be to use: [[UIDevice currentDevice] model]; And detect the existence of the string @"iPad" - which seems a bit fragile. In the 3.2 SDK, I see that UIDevice also has a property which is really what I'm looking for, but doesn't work for pre-3.2 (obviously): [[UIDevice currentDevice] userInterfaceIdiom]; Are there other ways than checking for the existence of @"iPad" for a universal app?

• Navigation properties not set when using ADO.NET Mocking Context Generator

  - by olenak

  I am using ADO.NET Mocking Context Generator plugin for my Entity Framework model. I have not started on using mocks yet, just trying to fix generated entity and context classes to make application run as before without exceptions. I've already fixed T4 template to support SaveChanges method. Now I've got another problem: when I try to access any navigation property it is set to null. All the primitive fields inherited from DB table are set and correct. So what I am doing is the following using (var context = MyContext()) { var order = context.Orders.Where(p => p.Id == 7); var product = order.Products; } in this case product is set to null. But that was not a case while using default code generator, it used to return real product object. Thanks ahead for any suggestions!

• What jquery based table plugin can hide sub rows?

  - by user1458290

  I'm in the need to convert excel macros into jquery code, the function is that you need to click on the plus sign to unfold and show the sub rows to modify column2 if you want to type values in column2, the other columns can't be modified. You can't straightly modify values of column2 until you unfold the parent row, because there are many sub rows belonging to parent row,say Car. The values of Name, Model, Code are existing, they are master data, no need to type or modify. please see the snapshot at folded and unfolded, besides modifying values in sub rows , I need to be able to know which sub rows are modified and values of those rows.Initially the editable columns are blank. And when you click on the minus sign, the sub rows can be folded again,but the modified values won't be lost,they are still there when unfolded again. One last requirement is it's cross devices, the code must run well on pc,mobile phone,pad. Is that possible? Many thanks.
