  • After extending the User model in django, how do you create a ModelForm?

    - by mlissner
    I extended the User model in django to include several other variables, such as location, and employer. Now I'm trying to create a form that has the following fields: First name (from User) Last name (from User) Location (from UserProfile, which extends User via a foreign key) Employer (also from UserProfile) I have created a modelform: from django.forms import ModelForm from django.contrib import auth from alert.userHandling.models import UserProfile class ProfileForm(ModelForm): class Meta: # model = auth.models.User # this gives me the User fields model = UserProfile # this gives me the UserProfile fields So, my question is, how can I create a ModelForm that has access to all of the fields, whether they are from the User model or the UserProfile model? Hope this makes sense. I'll be happy to clarify if there are any questions.

  • Extending Django-tagging, adding extra field to each tag?

    - by victorhooi
    heya, We're coding together a Django app to handle reviews of newspaper articles. Each newspaper article model will an arbitrary number of tags associated with it. Also, each tag will have an optional ranking (0 to 10). I was thinking of using django-tagging to do this (http://code.google.com/p/django-tagging/), but I'm not sure of the best way to add the ranking to the system. Should I extend django-tagging somehow? (Not sure if this is possible, without changing django-tagging's actual code?). Or is there a better way of achieving this? Cheers, Victor

  • Is it possible to build a JPA entity by extending a POJO?

    - by Freiheit
    Lets say I have the following POJO: public class MyThing { private int myNumber; private String myData; //assume getter/setter methods } Is it now possible to extend this POJO as a JPA entity? @Entity @Table(name = "my_thing") public class MyThingEntity extends MyThing implements Serializable { @Column(name = "my_number") //????????? @Column(name = "my_data") //???????? } I want to keep the POJO separate from the JPA entity. The POJO lives in a different project and is often used without a persistence layer, my project wants to persist it in a database and do so without the overhead of mapping from a POJO to an entity and back. I understand that JPA entities are POJOs, but in order to use it I would have to include a library that implements javax.persistence and the other projects using the same base object have no use for a persistence layer. Is this possible? Is this a good idea?

  • Extending LINQ classes to my own partial classes in different namespaces?

    - by sah302
    I have a .dbml file which of course contains the auto-generated classes based on my tables. I would however, like to extend them to my own classes. Typically I design such that each of my tables get their own namespace in their own folder containing all of their associated dao and service classes. So if I am dealing with a page that only has to do with 'customers' for instance, I can only include the customerNS. But when using LINQ I seem to be unable to do this. I have tried removing a default namespace from the project, I have tried putting the .dbml file into it's own folder with a custom namespace and then adding a 'using' statement, but no nothing works. I also saw the Entity Namespace, Context Namespace, and Custom Tool Namespace properties associated with the .dbml file and tried setting all these to names x and trying 'using x' in my other class to allow me to extend partial classes, but it just doesn't work. Is this possible or do I have to keep all extended partial classes in the same namespace as the .dbml file?

  • How do I avoid boxing/unboxing when extending System.Object?

    - by Robert H.
    I'm working on an extension method that's only applicable to reference types. I think, however, it's currently boxing and unboxing the the value. How can I avoid this? namespace System { public static class SystemExtensions { public static TResult GetOrDefaultIfNull<T, TResult>(this T obj, Func<T, TResult> getValue, TResult defaultValue) { if (obj == null) return defaultValue; return getValue(obj); } } } Example usage: public class Foo { public int Bar { get; set; } } In some method: Foo aFooObject = new Foo { Bar = 1 }; Foo nullReference = null; Console.WriteLine(aFooObject.GetOrDefaultIfNull((o) => o.Bar, 0)); // results: 1 Console.WriteLine(nullReference.GetOrDefaultIfNull((o) => o.Bar, 0)); // results: 0

  • extending Bash tab completion: how to handle paths / partial commands?

    - by Rawing
    I've added tab completion for my program to bash. It works quite well, but I don't know how to handle partial completion of words. Example: the user types ./program /home/user/De and presses TAB. This is then completed to ./program /home/user/Desktop/ , but there's now a trailing whitespace after 'Desktop/', which is not what I want. Basically, I need a way of preventing bash from adding whitespace after the completed word. I don't want to use bash's completion for paths.

  • Is it okay to just add a page or two PHP page to add some functionality to a Drupal site?

    - by Zaemz
    I'm not familiar with Drupal, really. I can dig around the admin interface and navigate the directories and find the files that I need to just fine as well. What I'm really not familiar with is adding modules or extending modules. The site currently takes an order and sets up recurring payments through Ubercart and uses Authorize.net as a gateway. Right now, when a payment fails, a single e-mail gets sent out to the admin. We'd like to extend it to send an e-mail to the user and let them change their payment information through another page on the site. Authorize has a service called Silent Post URL that basically just posts a carbon copy in XML to whatever URL you give it. We'd like to accept that XML, deserialize it, parse the data, send a notice to the user and give them the page for updating their information. So, I guess it'll be two PHP pages. One for the XML API call from Authorize.net, and then one for the page for the users' to update their payment information. Could I just create two simple pages each handling their own tasks, or should I check out properly extending a module? If it's appropriate for me to write up the pages and not have to hook them into the module, what would be the best way to handle setting up what needs to get done? (The most experience I've had with extending a PHP site has been hacking away at someone else' poorly constructed, custom framework, so if anyone has any good resources perhaps on PHP best practices that they could share through a PM or a comment, I'd appreciate It) (Also, I'm still getting the hang of Stack Exchange, so if this isn't appropriate please let me know. I'll delete it.)

  • May In Review

    - by Richard Bingham
    Content Highlights Our Application Composer series had fresh articles on the related internal data model and lots more on Groovy, including how to manipulate your data and a useful table showing you when and where groovy scripting can be used. For those just getting started with Fusion Applications user security, this article gave some handy examples to get your going. Jani's Java Cloud Service series continued strongly, with examples of integration using ADFbc, a Web Service Proxy client, and the ADF Data Control. From Other Teams The Oracle A-Team provided a broad set of articles during May, with various topics related to Fusion Applications including patching and performance management for on-premises deployments, and generic content on both integration and data extraction via web services. As part of their presentation to Oracle Israel User Group, our AppsUX colleagues explained the fresh new type of interface to Oracle Sales, through the voice mobile apps. This was in addition to demonstrations of the newer Release 8 Simplified UI customization options. Finally Angelo, our colleague in Platform Technical Services, explained in his blog how to use the findCriteria element included in all Oracle Sales web services to reduce the data returned, making response payloads much more specific, lightweight and therefore usable. Events and Announcements Oliver explained in this post about the new set of code samples on OTN for extending Sales Cloud using Oracle Platform as a Service. In addition, a new set of cloud developer documentation was released to provide more guided-learning on extending Oracle Sales Cloud with Oracle Platform as a Service (PaaS) services. This illustrative content is mainly as downloadable PDFs, and include topics covering sales cloud extensibility basics, using web services from JDeveloper (including security), using PaaS for SaaS development, and ADF (including mobile).

  • Why is a small fixed vocabulary seen as an advantage to RESTful services?

    - by Matt Esch
    So, a RESTful service has a fixed set of verbs in its vocabulary. A RESTful web service takes these from the HTTP methods. There are some supposed advantages to defining a fixed vocabulary, but I don't really grasp the point. Maybe someone can explain it. Why is a fixed vocabulary as outlined by REST better than dynamically defining a vocabulary for each state? For example, object oriented programming is a popular paradigm. RPC is described to define fixed interfaces, but I don't know why people assume that RPC is limited by these contraints. We could dynamically specify the interface just as a RESTful service dynamically describes its content structure. REST is supposed to be advantageous in that it can grow without extending the vocabulary. RESTful services grow dynamically by adding more resources. What's so wrong about extending a service by dynamically specifying a per-object vocabulary? Why don't we just use the methods that are defined on our objects as the vocabulary and have our services describe to the client what these methods are and whether or not they have side effects? Essentially I get the feeling that the description of a server side resource structure is equivalent to the definition of a vocabulary, but we are then forced to use the limited vocabulary in which to interact with these resources. Does a fixed vocabulary really decouple the concerns of the client from the concerns of the server? I surely have to be concerned with some configuration of the server, this is normally resource location in RESTful services. To complain at the use of a dynamic vocabulary seems unfair because we have to dynamically reason how to understand this configuration in some way anyway. A RESTful service describes the transitions you are able to make by identifying object structure through hypermedia. I just don't understand what makes a fixed vocabulary any better than any self-describing dynamic vocabulary, which could easily work very well in an RPC-like service. Is this just a poor reasoning for the limiting vocabulary of the HTTP protocol?

  • Defining work days and work time

    - by user2553268
    I'm working on development of SMS parking software, and I'm stuck at one point for a month... I need to implement periods of payment (or work time, of a work day, if you will). Here's the problem: For an example, traffic wardens work from Monday to Saturday. From Monday to Friday, the work times are from 07:00 to 21:00, and on Saturday, the work time is from 07:00 to 14:00. The project request was, that the customer can pay parking by SMS unlimited, which I did, but didn't implement this logic. I started with making a table for this periods of payment, it consists of: dayofweek (INT, for use with mysql function DAYOFWEEK, to tell me which day in week is the current date), work_start and work_stop (DATETIME, for defining starting and ending the work day), but I'm unsure if I should use DATETIME, beacuse of the date, or should I use only TIME. The idea is this: If you send an SMS, at 20:50, Monday, it should be valid until 07:50, Tuesday (it's payed by the hour). Extending the time of payment, regarding the work time in week. Currently, it works with extending time by the hour without this rule. Really would use some help, or some ideas, I'm stuck with this for quite some time...

  • Language Agnostic Basic Programming Question

    - by Rachel
    This is very basic question from programming point of view but as I am in learning phase, I thought I would better ask this question rather than having a misunderstanding or narrow knowledge about the topic. So do excuse me if somehow I mess it up. Question: Let's say I have class A,B,C and D now class A has some piece of code which I need to have in class B,C and D so I am extending class A in class B, class C, and class D Now how can I access the function of class A in other classes, do I need to create an object of class A and than access the function of class A or as am extending A in other classes than I can internally call the function using this parameter. If possible I would really appreciate if someone can explain this concept with code sample explaining how the logic flows. Note Example in Java, PHP and .Net would be appreciated.
