  • Good object/DB set-up for CMS-esque app for managing content and user permissions?

    - by sah302
    Hi all, so I am writing a big CMS-esque app to allow users to manage web content through web applications, I've got a pretty good db-driven user permission system going, but am having trouble coming up with a good way to handle content groups and pages, I've got a couple options and not sure which one to take. Furthermore, I am not sure how to handle static page updates that have no 'widgets' in them. My current set-up for permissions is this: Objects: User, UserGroup, UserUserGroup, UserGroupType Standard many to many relationship User -> UserUserGroup <- UserGroup each Usergroup has a UserGroupType, which could be anything from Title, Department, to PermissionGroup. PermissionGroup manages the permissions. Right now on a per page basis I check permissions based on their PermissionsGroups. So for a page which has CMS features for a news widget, I check for permission groups of "Site Admin" and "News Admin". Now the issue I am coming to is, the site has many different departments involved. No problem I think, I can just have a EntityContentGroup so any widget app can be used for any departments. So my HR department, each of their news items would be in the EntityContentGroup with the news item ID, and content group of "HR" or "HR News". But maybe this isn't the most efficient way to go about it? I don't want to put the content group simply as a NewsItemType because some news items could apply to multiple areas, so I want to be able to assign them to as many areas as I want. Likewise, all of my widget apps have this, so that's why I decided to choose EntityContentGroup and not just NewsItemContentGroup. I was also thinking well instead of doing a contentGroup do a Page object that says which page some entity should be on. It seems almost like the same thing, but would I want to use Page for something else? I was thinking Page would be used for static pages with no widgets, a simple Rich Text Editor can edit the content of that page and I save that item to a page?? And then instead of doing a page level check for UserGroup permissions, would it be better to associate a usergroup to a contentgroup, and then just depending on what contentGroup content on the page is displayed, determine the permissions through that relationship? Is that better? I am not sure at this point. I guess I am just getting a tad overwhelmed at this is the largest app in scope and size that I have ever written. What is the best approach for this based on my current user permission set-up?

  • transforming binary data using ssis and sql server 2008

    - by Rick
    Hello All - I have a task to import/transform and extract zipped binary files that contain both text data as well as embeded binary data. Within the data is data that is relational in nature and needs to be processed into a defined database structure. Currently I have a C# single threaded app that essentially grabs all the files from the directory (currently there is 13K files of varying sizes) and extracts the data on a single thread line by line inserts to the database. As you could imagine this is a very slow process and unacceptable. There are several different parsing routines used depending on the header record in the file. There are potentially upto a million rows per file when all the data is extracted to the row level of detail. Follow on task is to parse those rows into their appropriate tables based on is content. i.e. the textual content has to be parsed further into "buckets" of like data in the database. That about sums up the big picture. Now for the problem task list. How do i iterate through a packet of data using SSIS? In the app the file is decompressed and then is parsed using streams data type and byte arrays and is routed to the required parsing routine based on the header data of each packet. There is bit swapping involved as well. Should i wrap up the app code into a script task(s) and let it do the custom processing? The data is seperated by year and the sql server tables is partitioned by year as well. I need to be able to "catch" bad file data as well and process by hand most likely. Should i simply load the zipped file to sql as a blob and parse the file with T-SQL? Would that be multi threaded if done that way? Not sure how to do the parsing in tsql that is involved here. Which do you think would be faster? Potentially the data that is currently processed via files could come to us via a socket. Can SSIS collect that data in real time? How would i go about setting that up? Processing these new files from the directorys will become a daily task. I can manage the data once i get it to sql server. Getting it there in a timely fashion seems to be the long pole in the tent for me. I would appreciate any comments or suggestions from the group. Rick

  • How can I find the last value in a multidimensional array in php?

    - by Chris
    I am using a multidimensional array and I am trying to use php to find the last value of one of the arrays and based on that last number(value), add one more to it. Here is my multidimensional array structure: $_SESSION['cart']['add_complete'][1]['deck_id'] I am trying to create this structure, but instead of where it says 1 now, I want to find out what the last number in the add_complete array is and then add one more to it and put that in the place of the 1. How can I do that?

  • Active User Tracking, PHP Sessions

    - by Nik
    Alright, I'm trying to work on a function for active user counting in an AJAX based application. I want to express the below SQL Query in correct syntax but I'm not sure how to write it. The desired SQL Query is below: SELECT count(*) FROM active WHERE timestamp > time() - 1800 AND nick=(a string that doesn't contain [AFK]) Now, I do understand that time() - 1800 can be assigned to a variable, but how is timestamp > variable and nick that doesn't contain a string written in SQL?

  • Are there any protocols/standards on top of TCP optimized for high throughput and low latency?

    - by Nosrama
    Are there any protocols/standards that work over TCP that are optimized for high throughput and low latency? The only one I can think of is FAST. At the moment I have devised just a simple text-based protocol delimited by special characters. I'd like to adopt a protocol which is designed for fast transfer and supports perhaps compression and minification of the data that travels over the TCP socket.

  • Anybody using Qi4J

    - by Jon
    I was reading an InfoQ article on Composite Oriented Programming earlier on: http://www.infoq.com/articles/Composite-Programming-Qi4j I was interested in finding out whether anybody is currently using (or has used) the Qi4j framework at all? How does it compares to using a traditional dependency injection framework such as Spring for wiring classes together. Is the resulting object graph (based on mixins rather than classes) easier to deal with from a maintenance point of view?

  • Java force catch RuntimeException?

    - by wuntee
    Is it possible to force java to make you catch RuntimeExceptions? Specifically I am working with the Spring framework and the whole Exception hierarchy is based upon RuntimeExceptions. A lot of the times I forget to try and catch the Exceptions. A specific example is when doing an LDAP query, or an SQL call.

  • LinqToXML why does my object go out of scope? Also should I be doing a group by?

    - by Kettenbach
    Hello All, I have an IEnumerable<someClass>. I need to transform it into XML. There is a property called 'ZoneId'. I need to write some XML based on this property, then I need some decendent elements that provide data relevant to the ZoneId. I know I need some type of grouping. Here's what I have attempted thus far without much success. **inventory is an IEnumerable<someClass>. So I query inventory for unique zones. This works ok. var zones = inventory.Select(c => new { ZoneID = c.ZoneId , ZoneName = c.ZoneName , Direction = c.Direction }).Distinct(); No I want to create xml based on zones and place. ***place is a property of 'someClass'. var xml = new XElement("MSG_StationInventoryList" , new XElement("StationInventory" , zones.Select(station => new XElement("station-id", station.ZoneID) , new XElement("station-name", station.ZoneName)))); This does not compile as "station" is out of scope when I try to add the "station-name" element. However is I remove the paren after 'ZoneId', station is in scope and I retreive the station-name. Only problem is the element is then a decendant of 'station-id'. This is not the desired output. They should be siblings. What am I doing wrong? Lastly after the "station-name" element, I will need another complex type which is a collection. Call it "places'. It will have child elements called "place". its data will come from the IEnumerable and I will only want "places" that have the "ZoneId" for the current zone. Can anyone point me in the right direction? Is it a mistake select distinct zones from the original IEnumerable? This object has all the data I need within it. I just need to make it heirarchical. Thanks for any pointers all. Cheers, Chris in San Diego

  • Edit and Continue in Silverlight?

    - by Shnitzel
    Edit-And-Continue is one of my favorite debugging tools which I have previously used on C# based Winforms and ASP.NET projects. However, I'm running a Silverlight 3.0 application on VS 2008 and whenever I try to make a change (after breaking) it says "Changes are not allowed when debugging Silverlight applications". Also there isn't an "Enable Edit and Continue" option in the project settings. Does anyone (possibly an insider) know when this feature will be supported by Microsoft??? (I NEED IT!)

  • Errors caught by WBT, but not BBT and vice versa

    - by David Relihan
    Hi Folks, Can you think of one type of error that might be found using White-Box testing, and one type using Black-Box testing. i.e. an error that would be found by one and not the other. For WBT there would null else statements, but what would you catch with BBT and not WBT??? BTW this question is just based on my own personal study - I'm not getting free marks out of this!!!! Thanks,

  • Django Currency Conversion

    - by Koobz
    Is there any facility in Django for doing currency conversions? Obviously, rates change day by day but I'm somewhat hopeful that the locale module has some sort of web-service based converter :P There's a snippet here that handles the formatting: http://www.djangosnippets.org/snippets/552/ But I need to localize the values first.

  • Windows version of the Unix touch command

    - by Paul Hargreaves
    I'm looking for a Windows port of the UNIX touch command. I don't want to install an entire MKS toolkit just for the one tool. Is there a native port available somewhere or a command in Windows that does the same thing and supports features like all files in a directory by wildcard? Specifically I'm after changing mtime, ctime and atime for a project that reports ages of files based on... mtime, ctime and atime.
