  • general database modeling and django specific modeling

    - by Shreko
    I'm wondering what is the best way to model something like the following. Lets say my company sells metal bars (parameters/fields are: length, profile_type, quantity etc.) of different profiles, where profiles may be pipe(pipe_diameter, wall_thickness) or hollow_rectangle(base, height, wall_thickness), or maybe some other profile with different parameters. Lets say maximum number of profiles would be 12, each profile having between 2-5 parameters. Should everything be in a single table like table_bars: id, length, quantity, profile_type, pipe_diameter, wall_thickness, base, height, etc.) where profile type would be (pipe, rectangle etc.) or should every shape have its own table with its own parameters and in table_bars keep only id, length, quantity profile_type and profile_id) and are there any django specific issues is multiple tables are the best answer? Thanks

  • suggestions for Membership in ASP.NET MVC application

    - by mare
    With this question I am mostly looking for answers from people that have implemented the out-of-the-box ASP.NET membership in their own database - I've set up the tables inside my database and as far as I can see they contain mostly what I need but not everything. I will have the notion of a Firm (Company) to which Users will belong so I will have to associate the aspnet_Users with my Firms table (each user will be a member of exactly one firm). If possible, provide some guidelines how did you do it and what I might run into if I have to modify the table design at some point in the future. Preferably I will be using the default Membership provider. I am having trouble to decide whether to go from scratch or use what ASP.NET already offers.

  • Adding rows to UItableview and passing data between Viewcontrollers

    - by Jonathan
    I have a list of websites in a plist, when the app loads this populates a tableview (which is inside a navigation controller) But I have added an add button to the navigation bar and then created another View Controller to deal with inputting of the new website (Like Title and URL). It is very similar to how the contacts app looks. There is a table view and when you tap add, the add UI slides up. I have got all this working great so far. My Problem is what happens when the user taps Done. I can add the website to the plist (each website is a dictionary in the plist with 2 keys, atm) But then how do I tell the tableView to update? The table view has not been removed from the main window, just the add view has been added on top of the "screen". Another way of asking is, when you tap Save on Add a Contact screen: (not my image) How does the new contact's data (Xyz's data) get shown on the tableview?

  • Why Ubuntu Server asks to insert a CD-ROM when installed from PXE?

    - by MainMa
    I set up a PXE server which hosts both Ubuntu Desktop and Ubuntu Server. Ubuntu Desktop is installed successfully from PXE. Ubuntu Server seems to successfully load vmlinuz and initrd.gz, asks for the language, then the location, then the keyboard layout, and finally complains that it can't mount the CD-ROM: The content of /var/lib/tftpboot/pxelinux.cfg/default is the following: default ubuntu-installer/amd64/boot-screens/vesamenu.c32 menu title Ubuntu setup label ubuntu-14.04-desktop-amd64 menu label ubuntu-14.04-desktop-amd64 kernel ubuntu-14.04-desktop-amd64/vmlinuz.efi append initrd=ubuntu-14.04-desktop-amd64/initrd.lz root=/dev/nfs boot=casper netboot=nfs nfsroot=192.168.1.41:/exports/ubuntu-14.04-desktop-amd64 splash -- label ubuntu-14.04-server-amd64 menu label ubuntu-14.04-server-amd64 kernel ubuntu-14.04-server-amd64/vmlinuz append initrd=ubuntu-14.04-server-amd64/initrd.gz root=/dev/nfs boot=install netboot=nfs nfsroot=192.168.1.41:/exports/ubuntu-14.04-server-amd64 splash -- What explains the fact that it requests the CD-ROM and how to avoid it?

  • Learning language is enough to create average applications ?

    - by Freshblood
    Many books teach a programming language. However, knowing a specific language is not the same as knowning application or GUI design nor project layout. So, attempting to make an average application fails after learning a language. It is clear that knowing a language is not enough to make an application. If you agree with what I have said, why doesn't anyone mention this instead of teaching pure language syntax and features? Why books don't mention how to make a better application ?

  • Using PHP/MySQL with Google Maps

    - by Anders Kitson
    Hiya, I followed this tutorial below http://code.google.com/apis/maps/articles/phpsqlajax_v3.html#outputxml I ran into trouble, near then end, I am hoping someone else here has got this working and can help me discover my problem. Simply there are 4 steps to this tutorial Creating the Table Populating the Table Outputting XML with PHP Creating the Map I successfully have completed all the steps, however the outputted xml isn't read by the google map I created. The files are all on the same directory, and I didn't change any of the file names from the tutorial. The tutorial has a step to test if the php file called phpsqlajax_genxml.php is outputting the xml and I successfully tested it and it was. The problem is that the map isn't rendering the items I have in the database, that should be converted to xml for the map to read. Any help, or pointing me in the right direction would be much appreciated.

  • SSRS: Master-detail report with two datasources

    - by Svish
    I have two local data sources that I can push into the report. Works no problem. But how do I set up the report? One data source contains a list of employees, and info about them. The other contains a bunch of working hours for each employee. I would like to use a table for the list of employees, and then have another table for the working hours beneath each employee (with their working hours). Is this even possible? Do I have to use a Sub-Report? Would I have to merge them into one datasource? =/

  • Form repeats values

    I have a dynamically generated form to accept guest details and store the results into the a session array.

  • MS SQL Server 15MM rows, simple COUNT query. 15+ seconds?

    - by john
    We took over a website from another company after a client decided to switch. We have a table that grows by about 25k records a day, and is currently at 15MM records. The table looks something like: id (PK, int, not null) member_id (int, not null) another_id (int, not null) date (datetime, not null) SELECT COUNT(id) FROM tbl can take up to 15 seconds. A simple inner join on 'another_id' takes over 30 seconds. I can't imagine why this is taking so long. Any advice? SQL Server 2005 Express

  • Convert a PDF eBook to ePub Format

    - by Matthew Guay
    Would you like to read a PDF eBook on an eReader or mobile device, but aren’t happy with the performance? Here’s how you can convert your PDFs to the popular ePub format so you can easily read them on any device. PDFs are a popular format for eBooks since they render the same on any device and can preserve the exact layout of the print book.  However, this benefit is their major disadvantage on mobile devices, as you often have to zoom and pan back and forth to see everything on the page.  ePub files, on the other hand, are an increasingly popular option. They can reflow to fill your screen instead of sticking to a strict layout style.  With the free Calibre program, you can quickly convert your PDF eBooks to ePub format. Getting Started Download the Calibre installer (link below) for your operating system, and install as normal.  Calibre works on recent versions of Windows, OS X, and Linux.  The Calibre installer is very streamlined, so the install process was quite quick. Calibre is a great application for organizing your eBooks.  It can automatically sort your books by their metadata, and even display their covers in a Coverflow-style viewer. To add an eBook to your library, simply drag-and-drop the file into the Calibre window, or click Add books at the top.  Here you can choose to add all the books from a folder and more. Calibre will then add the book(s) to your library, import the associated metadata, and organize them in the catalog. Convert your Books Once you’ve imported your books into Calibre, it’s time to convert them to the format you want.  Select the book or books you want to convert, and click Convert E-books.  Select whether you want to convert them individually or bulk convert them. The convertor window has lots of options, so you can get your ePub book exactly like you want.  You can simply click Ok and go with the defaults, or you can tweak the settings. Do note that the conversion will only work successfully with PDFs that contain actual text.  Some PDFs are actually images scanned in from the original books; these will appear just like the PDF after the conversion, and won’t be any easier to read. On the first tab, you’ll notice that Calibri will repopulate most of the metadata fields with info from your PDF.  It will also use the first page of the PDF as the cover.  Edit any of the information that may be incorrect, and add any additional information you want associated with the book. If you want to convert your eBook to a different format other than ePub, Calibri’s got you covered, too.  On the top right, you can choose to output the converted eBook into a many different file formats, including the Kindle-friendly MOBI format. One other important settings page is the Structure Detection tab.  Here you can choose to have it remove headers and footers in the converted book, as well as automatically detect chapter breaks. Click Ok when you’ve finished choosing your settings and Calibre will convert the book.  This may take a few minutes, depending on the size of the PDF.  If the conversion seems to be taking too long, you can click Show job details for more information on the progress.   The conversion usually works good, but we did have one job freeze on us.  When we checked the job details, it indicated that the PDF was copy-protected.  Most PDF eBooks, however, worked fine. Now, back in the main Calibri window, select your book and save it to disk.  You can choose to save only the EPUB format, or you can select Save to disk to save all formats of the book to your computer. You can also view the ePub file directly in Calibri’s built-in eBook viewer.  This is the PDF book we converted, and it looks fairly good in the converted format.  It does have some odd line breaks and some misplaced numbers, but on the whole, the converted book is much easier to read, especially on small mobile devices.   Even images get included inline, so you shouldn’t be missing anything from the original eBook. Conclusion Calibri makes it simple to read your eBooks in any format you need. It is a project that is in constant development, and updates regularly adding better stability and features.  Whether you want to ready your PDF eBooks on a Sony Reader, Kindle, netbook or Smartphone, your books will now be more accessible than ever.  And with thousands of free PDF eBooks out there, you’ll be sure to always have something to read. If you’d like some Geeky PDF eBooks, Microsoft Press is offering a number of free PDF eBooks right now.  Check them out at this link (Account Required).

  • How to avoid using duplicate savepoint names in nested transactions in nested stored procs?

    - by Gary McGill
    I have a pattern that I almost always follow, where if I need to wrap up an operation in a transaction, I do this: BEGIN TRANSACTION SAVE TRANSACTION TX -- Stuff IF @error <> 0 ROLLBACK TRANSACTION TX COMMIT TRANSACTION That's served me well enough in the past, but after years of using this pattern (and copy-pasting the above code), I've suddenly discovered a flaw which comes as a complete shock. Quite often, I'll have a stored procedure calling other stored procedures, all of which use this same pattern. What I've discovered (to my cost) is that because I'm using the same savepoint name everywhere, I can get into a situation where my outer transaction is partially committed - precisely the opposite of the atomicity that I'm trying to achieve. I've put together an example that exhibits the problem. This is a single batch (no nested stored procs), and so it looks a little odd in that you probably wouldn't use the same savepoint name twice in the same batch, but my real-world scenario would be too confusing to post. CREATE TABLE Test (test INTEGER NOT NULL) BEGIN TRAN SAVE TRAN TX BEGIN TRAN SAVE TRAN TX INSERT INTO Test(test) VALUES (1) COMMIT TRAN TX BEGIN TRAN SAVE TRAN TX INSERT INTO Test(test) VALUES (2) COMMIT TRAN TX DELETE FROM Test ROLLBACK TRAN TX COMMIT TRAN TX SELECT * FROM Test DROP TABLE Test When I execute this, it lists one record, with value "1". In other words, even though I rolled back my outer transaction, a record was added to the table. What's happening is that the ROLLBACK TRANSACTION TX at the outer level is rolling back as far as the last SAVE TRANSACTION TX at the inner level. Now that I write this all out, I can see the logic behind it: the server is looking back through the log file, treating it as a linear stream of transactions; it doesn't understand the nesting/hierarchy implied by either the nesting of the transactions (or, in my real-world scenario, by the calls to other stored procedures). So, clearly, I need to start using unique savepoint names instead of blindly using "TX" everywhere. But - and this is where I finally get to the point - is there a way to do this in a copy-pastable way so that I can still use the same code everywhere? Can I auto-generate the savepoint name on the fly somehow? Is there a convention or best-practice for doing this sort of thing? It's not exactly hard to come up with a unique name every time you start a transaction (could base it off the SP name, or somesuch), but I do worry that eventually there would be a conflict - and you wouldn't know about it because rather than causing an error it just silently destroys your data... :-(

  • Using a PreparedStatement to persist an array of Java Enums to an array of Postgres Enums

  • How to stop event bubbling with jquery live?

    - by chobo2
    Hi I am trying to stop some events but stopPropagation does not work with "live" so I am not sure what to do. I found this on their site. Live events do not bubble in the traditional manner and cannot be stopped using stopPropagation or stopImmediatePropagation. For example, take the case of two click events - one bound to "li" and another "li a". Should a click occur on the inner anchor BOTH events will be triggered. This is because when a $("li").bind("click", fn); is bound you're actually saying "Whenever a click event occurs on an LI element - or inside an LI element - trigger this click event." To stop further processing for a live event, fn must return false It says that fn must return false so what I tried to do $('.MoreAppointments').live('click', function(e) { alert("Hi"); return false; }); but that did not work so I am not sure how to make it return false. Update Here is some more information. I have a table cell and I bind a click event to it. $('#CalendarBody .DateBox').click(function(e) { AddApointment(this); }); So the AddApointment just makes some ui dialog box. Now the live code(MoreAppointments) sits in this table cell and is basically an anchor tag. So when I click on the anchor tag it first goes to the above code(addApointment - so runs that event first) runs that but does not launch my dialog box instead it goes straight to the (MoreAppointment) event and runs that code. Once that code has run it launches the dialog box from "addApointment". Update 2 Here is some of the html. I did not copy the whole table since it is kinda big and all the cells repeat itself with the same data. If needed I will post it. <td id="c_12012009" class="DateBox"> <div class="DateLabel"> 1</div> <div class="appointmentContainer"> <a class="appointments">Fkafkafk fakfka kf414<br /> </a><a class="appointments">Fkafkafk fakfka kf414<br /> </a><a class="appointments">Fkafkafk fakfka kf414<br /> </a><a class="appointments">Fkafkafk fakfka kf414<br /> </a><a class="appointments">Fkafkafk fakfka kf414<br /> </a> </div> <div class="appointmentOverflowContainer"> <div> <a class="MoreAppointments">+1 More</a></div> </div> </td>

  • how to use Foreign key in L2E or EF?

    - by 5YrsLaterDBA
    I have a User table which has a PrivilegeId foreign key points to a Privilege table and is the primary key there. In Entity Framework, the VS will not generate a PrivilegeId variable under Users for you. It will generate a Privilege property and PrivilegeReference property for you instead. When I load a User, the Privilege property is null by default. That means EF does not load refered entity for you automatically. I think I may did something wrong? I cannot load Privilege separatedly because I have no info about the Privilege at that time. I guess EF should load the refered entities for me but I missed something. anybody can help me?

  • Advices and strategies for browser compatibility on web applications into a corporate environment

    - by TiagoBrenck
    With the new CSS 3 and HTML 5 tecnology, the web applications gained a lot of new tools for a better UI(user interface) interaction, beautifull templates and even responsive layout to fit into tablets and smartphones. Within a corporate environment, those new tecnologies are required so the company can "follow" the IT evolution and their concurrent, but they also want that those new web applications supports old browsers. How to deal with this situation? By one side we are asked to follow the news and IT evolutions, create responsive layouts and use a lot of cool jQuery's plugins. And by the other side, we are asked to support old browsers that doesn't support those new responsive features, plugins or components. I would like advices and strategies to create "modern" web applications that are also supported on old browsers. How does your company deal with this situation? Is it possible to have the same web application running good and beauty on old browsers, and responsive, interactive on actual browsers?

  • Repairing malformatted html attributes using c#

    - by jhoefnagels
    I have a web application with an upload functionality for HTML files generated by chess software to be able to include a javascript player that reproduces a chess game. I do not like to load the uploaded files in a frame so I reconstruct the HTML and javascript generated by the software by parsing the dynamic parts of the file. The problem with the HTML is that all attributes values are surrounded with an apostrophe instead of a quotation mark. I am looking for a way to fix this using a library or a regex replace using c#. The html looks like this: <DIV class='pgb'><TABLE class='pgbb' CELLSPACING='0' CELLPADDING='0'><TR><TD> and I would transform it into: <DIV class="pgb"><TABLE class="pgbb" CELLSPACING="0" CELLPADDING="0"><TR><TD>
