  • Warn user when new data is inserted on database

    - by João Menighin
    I don't know how to search about this so I'm kinda lost (the two topics I saw here were closed). I have a news website and I want to warn the user when a new data is inserted on the database. I want to do that like here on StackOverflow where we are warned without reloading the page or like in facebook where you are warned about new messages/notifications without reloading. Which is the best way to do that? Is it some kind of listener with a timeout that is constantly checking the database? It doesn't sounds efficient... Thanks in advance.

  • Create a link to delete membership in web2py

    - by user1741325
    I'm trying to do something really simple but it's taking me ages to figure out how to do it properly. I want to have a button that simply deletes a member from a group. So in my view I have <div id="del-role">{{=A('Delete Role',_class="btn btn-danger", callback=URL('test'),delete='#del-role')}}</div> However, when I click the button, the only thing I get is a Javascript prompt asking whether I'm sure I want to delete the specified object, yes/no. That's fine but, what I'd really like to do is just auth.del_membership('role') What needs to go in my controller? I do not want any page redirection, I just want to auth.del_membership(role) This seemingly simple thing is taking me forever to understand. Thanks!

  • Django form to enter/save html to database

    - by Ian
    I'm in my first week of Django development and am working on an admin page that will let me write some quick html using TinyMCE and then save it to the database. I don't need to display this web page on the site or add it to urls.py, etc. The html snippet will be loaded from the database and used in a view function. I've read in "Practical Django Projects" how to integrate TinyMCE, so my question is more concerned with the best approach for the form itself. Specifically: 1. Is there a built-in form like flatpage that works well for this? I only need one field in the form for the html. 2. How do I save the form's text after it's entered? I created a model with a JSONField to save the html in, but I'm not clear on what to do next. Thanks.

  • Update database using restful ASP.NET MVC 1.0

    - by Mike
    We are building an MVC 1.0 application right now and using Linq - SQL for our DAL. Following the restful approach we have multiple action events depending on if you are updating or loading or what not. The two that I'm concerned with at this point are the edit and update action methods. Here is the signatures. public ActionResult Update(int customerId, int Id, AggregateModel viewModel) public ActionResult Edit(int customerId, int Id, AggregateModel viewModel) So the idea is that in the Edit method we load up our viewModel and pass it to the view. The user makes changes to the model and then posts back to the Update method. The first thing I could think of to do would be to get the viewModel from the database again, copy the changes in one by one from the posted back model and then submit it back. This would work but does seem clunky to me. What is the best way to insert those changes into the database at this point?

  • How can I tell if a SQL Server database is being backed up

    - by Guy
    Is there a way to programmatically determine if a SQL Server backup is currently being performd on a particular database? We have automated database backup scripts for both data and log files, where the databases are backed up nightly and log files are backed up every 15 minutes, 24 hours a day. However, we think that the log file backup job is failing if it runs the same time as the full backup is being run. What I'd like to do is to make a change to my transaction log script to not run a transaction log backup while the full backup is being run. If there a DMV or a system table that I can query and work this out?

    - by lance_klusener
    Hello All, I am new to web application development, so sorry in advance if this question is too basic. The following are the details of the question: A] Platform being used -- google app engine with python, django. B] Tutorial link being used -- http://code.google.com/appengine/articles/djangoforms.html C] Question: In the application i am building, there is a drop down box which allows the user to select their country.

  • Reset after using a link with parameters

    - by CarolinaJay65
    I am using the window.location.search parameters (www.mysite.com?page=1) to direct the user to a specific page within the site. However, since those parameters are still in window.location (the browser) reset button continues to re-direct to the same page. I would like the reset button to re-direct to www.mysite.com How do I clear the .search parameters so the (browser) reset button re-directs where I want? Is it done after the page is loaded? or after the (browser) reset button has been clicked?

  • Manipulating/changing adressbar link Help

    - by Karem
    I am out of my own "ideas" going through this. I have a album viewer. When you click next I want the adressbar to hang with it, e.g if you start on ?photoid=1, and click next (next picture appends and stuff), and then i want it to say ?photoid=2. Now I cant make it say ?photoid=2 without changing/manipulating, and this you cant do without HTML5. I have made a script in HTML5 that works fine, but then I need to take care of those who dont have HTML5(only chrome, ff4 etc supports html5) Made the script from this( https://developer.mozilla.org/en/DOM/Manipulating_the_browser_history ) I thought of adding #photoid=2 so, ?photoid=1#photoid=2 and then check if theres anything in # then use that instead of the $_GET.. But apparently you cannot do that as # is client side handled and never sent to the server. So what should I then do? Any suggestions please to make a workaround this? I checked facebook, what they did to IE users, and I could hear that it "clicked" (the annoying click sound from IE) twice.. the first was to get to the next picture, the second click sound changed the adressbar?!(how?). And then I also thought hey, html5 is only supported in ff4, and I got ff3.6, and they manipulate the adress bar url when you browse through the album photos, exactly like how I wanted (and what I have written for but it only works in Chrome and ff4..?). How could they do that?

  • Drupal removing javascript from Full HTML link

    - by Jen
    I am new to Drupal and am trying to create a node (let's call it child) that will only really be accessed when clicked on from another node (we'll call it parent). When closing the child window, I want to parent window to refresh. Outside of Drupal, that's easy: <a onclick="window.close(); window.opener.location.reload();" href="#">Click to close this window</a> However, when I type this into the body of a node using Full HTML, it still strips the onclick text from my post. How can I include javascript in the body of a node like this? Is there a special module I need. Thanks!

  • Can't connect to MySQL database hosted in CloudBees

    - by user3692698
    I have a free CloudBees account and created a free ClearDB database using their wizards. My trouble is when I use their connection information (whether I try to connect from my Java app, or an outside tool - SQLyog to be exact) I take the error: Access denied for user 'b51dbc5757d79f'@'%' to database 'mywiki. The username provided by CloudBees does not contain those extra characters that the error message is displaying which seems like it would be a problem, but I'm not sure there is anything I can do about that since everything is configured for me. The username I am given is: b51dbc5757d79f - which I can delete and rebuild after sharing here :)

  • Experience with Intel X25-M 160GB and Oracle

    - by derobert
    We're considering building an Oracle database with 12 Intel X25-M G2 160GB drives in software RAID10. It'd be running Linux. Database gets some very heavy write activity during the early morning data load, other than that it is mostly read-only (and the read load is fairly minimal). We're currently running on 11 150GB Velociraptors (also Linux software RAID10), and are hoping the X25-M will speed up the data load. We currently have redo on different disks than the rest of the data. I'm wondering a few things: Any experience with using X25-M drives for databases? The X25-E are unfortunately beyond our budget. Would it hurt to separate redo off to some magnetic (non-SSD) drives, say 2 (raid1) or 4 (raid10) Seagate Constellations?

  • SQL database self interaction entity

    - by Ricardo Costa
    I've been working on a database, wich is referent to an Aeroport management. I'm having a problem that it's freaking me out.. What i'm trying to do is, assuming that a client wants to know the distance between 2 locations, in miles or kms. As an example, if the user wants to know the distance between London and Amsterdam, should that distance be calculated by a formule or should it be already stored on the database? (1,N) ____________ ____________|__ | | | | | City/Airport |<---------| |______________| How can i show to user the distance between his 2 choices? RicardoCosta

  • Question on different ways to link tables

    - by dotnetdev
    What is the difference between linking two tables and then the PK is an FK in the other table, but the FK has not got the primary key option (so it does not have the gold key), and having the PK in one table as a PK in another table? Am I right to think that the second option is for a many-to-many relationship? Thanks

  • If a SQL Server Replication Distributor and Subscriber are on the same server, should a PUSH or PULL subsciption be used?

    - by userx
    Thanks in advance for any help. I'm setting up a new Microsoft SQL Server replication and I have the Distributor and Subscriber running on the same server. The Publisher is on a remote server (as it is a production database and MS recommends that for high volumes, the Distributor should be remote). I don't know much about the inner workings of PUSH vs PULL subscriptions, but my gut tells me that a PUSH subscription would be less resource intensive because (1) the Distributor is already remote, so this shouldn't negatively effect the Publisher and (2) pushing the transactions from the Distributor to the Subscriber is more efficient than the Subscriber polling the Distribution database. Does any one have any resources or insight into PUSH vs PULL which would recommend one over the other? Is there really going to be that big of a difference in performance / reliability / security?

  • Entity Framework 4 Hiding Underlying Resolver Tables when model is generated from database

    - by grrrrrrrrrrrrr
    When creating an entity framework model from scratch it is possible to specify a Many to Many relationship in the model. e.g Entity1 * ----- * Entity2 When a database is then generated from this, a resolver table is then created automatically between the two entities, this is hidden in the code model, allowing direct access to each of the entities via properties. e.g. Entity1 ----* ResolverEntity *----- Entity2 My question is, when a model is generated from an existing database, which contains resolver tables, is it possible to create the same effect so the resolver tables do not appear in the generated object model? When I have attempted this, the entity framework appears to create entities in the model for the resolver tables with no obvious way of hiding them in the object model. Thanks.
