  • Selecting based on __key__ (a unique identifier) in google appengine [Java]

    - by Stavros
    I have public class QuantityType { @PrimaryKey @Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY) private Key key; @Persistent private String type; } I am trying to setup a query to get the right QuantityType by it's key gql = "select * from QuantityType where __key__='aght52oobW1hIHTWVzc2FnZRiyAQw'"; But its not working because BadFilterError: BadFilterError: invalid filter: key filter value must be a Key; received aght52oobW1hIHTWVzc2FnZRiyAQw (a str). I have also tried to use gql = "select * from QuantityType where __key__=='" + KeyFactory.stringToKey(qTypeKey)+"'"; but it's now working.. How can I get a specific object from my datastore by it's key?

  • Ria Services loading foreign keys with Linq-to-SQL

    - by Stephan
    I have a database that consists of 5 tables : Course, Category, Location, CourseCategories, and CourseLocations. The last 2 tables just contain the two foreign keys. A Course has many-to-many relationships with both category and location. I am trying to load the data into a Silverlight app using Ria Services. My DB model is Linq-to-SQL. I have tried adding the [Include] attribute to the metadata classes and I have added the DataLoadOptions so it should load the all tables when you ask for a Course. However on the client side I am never getting back any entries in the CourseCategories and CourseLocations properties. What else needs to be done to get the foreign key relationships to exist across the serialization.

  • Field contains foreign IDs for different tables

    - by Rich
    I am developing a php/mysql driven facebook game. I am stuck on an element the table design. When a user completes a task I want to trigger any number of events. I was thinking of something like so: tbl_events *event_id - serogate primary ID *task_id - foreign ID of the task just completed *event_type - what type of event e.g is it a facebook stream publish or a message to the user or does it unlock a new element of the game? *event_param - this is where it gets tricky... the event parameter is a problem for two reasons, 1) it will contain different foreign ids... dependent on the event_type and thus it will not be possible to join to x table. Meaning I would have to call two queries. 2) Most events require a single id or text, however some events require multiple parameters - like the facebook stream publish.

  • Change list link to foreign key change page

    - by Adam
    When viewing the admin change list for a model, is it possible to make the columns that correspond to foreign keys links to their respective pages? A simple example is I have a Foo object which contains Bar as a foreign key. If I'm viewing the admin change list for Foo (and have it set to include Bar in the display_list columns), the main column would link to the Foo instance's edit page while the Bar column would link to the Boo instance's edit page. I understand I can override the template that's used, but I was curious if there was a solution that didn't require that.

  • SQL update a table with a foreign key

    - by drousseau
    I have a categories table, which one of the fields serves as the foreign key for a sub-categories table. One field that serves as part of the primary key for each table is the language id. I need to update these in both tables. Basically, wherever the language id = x in both tables, I need to set it to y. When I try to do an update on either table, I get a 'The UPDATE statement conflicted with the REFERENCE constraint..' which refers to the foreign key constraint. How can I update the language field on both of these tables?

  • Three Key Tenets of Optimal Social Collaboration

    - by kellsey.ruppel
    Today's blog post comes to us from John Bruswick! This post is an abridged version of John’s white paper in which he discusses three principals to optimize social collaboration within an enterprise.   By [email protected], Oracle Principal Sales Consultant Effective social collaboration is actionable, deeply contextual and inherently derives its value from business entities outside of itself. How does an organization begin the journey from traditional, siloed collaboration to natural, business entity based social collaboration? Successful enablement of enterprise social collaboration requires that organizations embrace the following tenets and understand that traditional collaborative functionality has inherent limits - it is innovation and integration in accordance with the following tenets that will provide net-new efficiency benefits. Key Tenets of Optimal Social Collaboration Leverage a Ubiquitous Social Fabric - Collaborative activities should be supported through a ubiquitous social fabric, providing a personalized experience, broadcasting key business events and connecting people and business processes.  This supports education of participants working in and around a specific business entity that will benefit from an implicit capture of tacit knowledge and provide continuity between participants.  In the absence of this ubiquitous platform activities can still occur but are essentially siloed causing frequent duplication of effort across similar tasks, with critical tacit knowledge eluding capture. Supply Continuous Context to Support Decision Making and Problem Solving - People generally engage in collaborative behavior to obtain a decision or the resolution for a specific issue.  The time to achieve resolution is referred to as "Solve Time".  Users have traditionally been forced to switch or "alt-tab" between business systems and synthesize their own context across disparate systems and processes.  The constant loss of context forces end users to exert a large amount of effort that could be spent on higher value problem solving. Extend the Collaborative Lifecycle into Back Office - Beyond the solve time from decision making efforts, additional time is expended formalizing the resolution that was generated from collaboration in a system of record.  Extending collaboration to result in the capture of an explicit decision maximizes efficiencies, creating a closed circuit for a particular thread.  This type of structured action may exist today within your organization's customer support system around opening, solving and closing support issues, but generally does not extend to Sales focused collaborative activities. Excelling in the Unstructured Future We will always have to deal with unstructured collaborative processes within our organizations.  Regardless of the participants and nature of the collaborate process, two things are certain – the origination and end points are generally known and relate to a business entity, perhaps a customer, opportunity, order, shipping location, product or otherwise. Imagine the benefits if an organization's key business systems supported a social fabric, provided continuous context and extended the lifecycle around the collaborative decision making to include output into back office systems of record.   The technical hurdle to embracing optimal social collaboration would fall away, leaving the company with an opportunity to focus on and refine how processes were approached.  Time and resources previously required could then be reallocated to focusing on innovation to support competitive differentiation unique to your business. How can you achieve optimal social collaboration? Oracle Social Network enables business users to collaborate with each other using a broad range of collaboration styles and integrates data from a variety of sources and business applications -- allowing you to achieve optimal social collaboration. Looking to learn more? Read John's white paper, where he discusses in further detail the three principals to optimize social collaboration within an enterprise.

  • Cascading Deletes in SQL Sever 2008 not working.

    - by Vaccano
    I have the following table setup. Bag | +-> BagID (Guid) +-> BagNumber (Int) BagCommentRelation | +-> BagID (Int) +-> CommentID (Guid) BagComment | +-> CommentID (Guid) +-> Text (varchar(200)) BagCommentRelation has Foreign Keys to Bag and BagComment. So, I turned on cascading deletes for both those Foreign Keys, but when I delete a bag, it does not delete the Comment row. Do need to break out a trigger for this? Or am I missing something? (I am using SQL Server 2008) Note: Posting requested SQL. This is the defintion of the BagCommentRelation table. (I had the type of the bagID wrong (I thought it was a guid but it is an int).) CREATE TABLE [dbo].[Bag_CommentRelation]( [Id] [int] IDENTITY(1,1) NOT NULL, [BagId] [int] NOT NULL, [Sequence] [int] NOT NULL, [CommentId] [int] NOT NULL, CONSTRAINT [PK_Bag_CommentRelation] PRIMARY KEY CLUSTERED ( [BagId] ASC, [Sequence] ASC )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY] ) ON [PRIMARY] GO ALTER TABLE [dbo].[Bag_CommentRelation] WITH CHECK ADD CONSTRAINT [FK_Bag_CommentRelation_Bag] FOREIGN KEY([BagId]) REFERENCES [dbo].[Bag] ([Id]) ON DELETE CASCADE GO ALTER TABLE [dbo].[Bag_CommentRelation] CHECK CONSTRAINT [FK_Bag_CommentRelation_Bag] GO ALTER TABLE [dbo].[Bag_CommentRelation] WITH CHECK ADD CONSTRAINT [FK_Bag_CommentRelation_Comment] FOREIGN KEY([CommentId]) REFERENCES [dbo].[Comment] ([CommentId]) ON DELETE CASCADE GO ALTER TABLE [dbo].[Bag_CommentRelation] CHECK CONSTRAINT [FK_Bag_CommentRelation_Comment] GO The row in this table deletes but the row in the comment table does not.

  • Using Constraints on Hierarchical Data in a Self-Referential Table

    - by pbarney
    Suppose you have the following table, intended to represent hierarchical data: +--------+-------------+ | Field | Type | +--------+-------------+ | id | int(10) | | parent | int(10) | | name | varchar(45) | +--------+-------------+ The table is self-referential in that the parent_id refers to id. So you might have the following data: +----+--------+---------------+ | id | parent | name | +----+--------+---------------+ | 1 | 0 | fruit | | 2 | 0 | vegetable | | 3 | 1 | apple | | 4 | 1 | orange | | 5 | 3 | red delicious | | 6 | 3 | granny smith | | 7 | 3 | gala | +----+--------+---------------+ Using MySQL, I am trying to impose a (self-referential) foreign key constraint upon the data to update on cascades and prevent deletion of fruit if they have "children." So I used the following: CREATE TABLE `idtlp_main`.`fruit` ( `id` INT(10) UNSIGNED NOT NULL AUTO_INCREMENT, `parent` INT(10) UNSIGNED, `name` VARCHAR(45) NOT NULL, PRIMARY KEY (`id`), CONSTRAINT `fk_parent` FOREIGN KEY (`parent`) REFERENCES `fruit` (`id`) ON UPDATE CASCADE ON DELETE RESTRICT ) ENGINE = InnoDB; From what I understand, this should fit my requirements. (And parent must default to null to allow insertions, correct?) The problem is, if I change the id of a record, it will not cascade: Cannot delete or update a parent row: a foreign key constraint fails (`iddoc_main`.`fruit`, CONSTRAINT `fk_parent` FOREIGN KEY (`parent`) REFERENCES `fruit` (`id`) ON UPDATE CASCADE) What am I missing? Feel free to correct me if my terminology is screwed up... I'm new to constraints.

  • Django Forms, Foreign Key and Initial retuen all associated values

    - by gramware
    I a working with Django forms. The issue I have is that Foreign Key fields and those using initial take all associated entries (all records associated with that record other then the one entry i wanted e.g instead of getting a primary key, i get the primary key, post subject, post body and all other values attributed with that record). The form and the other associated queries still work well, but this behaviour is clogging my database. How do i get the specific field i want instead of all records. An example of my models is here: A form field for childParentId returns postID, postSubject and postBody instead of postID alone. Also form = ForumCommentForm(initial = {'postSubject':forum.objects.get(postID = postID), }) returns all records related to postID. class forum(models.Model): postID = models.AutoField(primary_key=True) postSubject = models.CharField(max_length=25) postBody = models.TextField() postPoster = models.ForeignKey(UserProfile) postDate = models.DateTimeField(auto_now_add=True) child = models.BooleanField() childParentId = models.ForeignKey('self',blank=True, null=True) deleted = models.BooleanField() def __unicode__(self): return u'%s %s %s %s %s' % (self.postSubject, self.postBody, self.postPoster, self.postDate, self.postID

  • Running Ubuntu Server from a USB key / thumb drive (being mindful of flash's write limitations)

    - by andybjackson
    Having become disillusioned with hacking Buffalo NAS devices, I've decided to roll my own home server. After some research, I have settled on an HP Proliant Microserver with Ubuntu Server and a ZFS RAID-Z array for data. I settled on this configuration after trying and regretfully rejecting FreeNAS because the Logitech Media Server (LMS) software isn't available on the AMD64 flavour of this platform and because I think Debian/Ubuntu server is a better future-proof platform. I considered Open Media Vault, but concluded that it isn't quite yet ready for my purposes. That said, FreeNAS does include the option to run itself off a 2GB+ flash device like USB key or thumb drive. Apparently FreeNAS is mindful of the write limitations of flash devices and so creates virtual disks for running the OS, writing only the required configuration information back to flash. This would give me an extra data drive slot. Q: Can Ubuntu Server be configured sensibly to run off a flash device such as a USB key/thumb drive? If so, how? The write limitations of flash should be accounted for.

  • Map specific keys in emacs - Ubuntu

    - by Josh
    On my Mac, I have remapped the capslock key to be another Ctrl, and the key to the right of control to be M (meta?). It was real easy, the capslock was in sys prefs, and the M key was a pref in terminal. I cannot figure out how to do it on my Ubuntu 10.10 computer though. There was no remap capslock that I could find under any of the three keyboard pref menu items, and there are no prefs under the terminal that I can find. Can someone advise? I want the windows key on the keyboard to be M, if that matters. tl;dr; Ubuntu 10.10: Map capslock as Ctrl and Windows key as Meta (emacs) Thanks! EDIT: Found Capslock under System - Prefs - Keyboard - Layouts - USA - Options - Ctrl Key Position - Make CapsLock an additional Ctrl
