  • Are there any PHP Frameworks (e.g. CodeIgniter) that support database connections on a per user acco

    - by Brad G
    I'm looking into developing a multi-tenant SaaS application, and I found several sites that describe a solid way to separate the data using tenantIDs and updateable views. e.g. This blog post It all hinges on the ability to have your user accounts authenticated from a master users table and then having their respective database connections use those user-specific credentials. This way, the views can pull the userid and map it to the tenantID to display that user's view. However, most PHP frameworks tend to be very static when it comes to database connections (stored in text config files). They appear to be at odds. Does anyone know: a) how to make CodeIgniter handle this gracefully? b) a different PHP framework that might?

  • Can Android OS be programmed to interface with a external device via the mini-USB port?

    - by user322865
    Basic example, if I bought a chipset with a light socket and bulb soldered to the chipset; then put a USB cable with the mini-USB plug on the end to get plugged into the android phone. Can I write a Java application to turn on/off the light, get the status of the light(on/off) and maybe power a super-small led/bulb with power from the phone itself? Any insight at all would be greatly appreciated. Thank you

  • Can a binary tree or tree be always represented in a Database table as 1 table and self-referencing?

    - by Jian Lin
    I didn't feel this rule before, but it seems that a binary tree or any tree (each node can have many children but children cannot point back to any parent), then this data structure can be represented as 1 table in a database, with each row having an ID for itself and a parentID that points back to the parent node. That is in fact the classical Employee - Manager diagram: one boss can have many people under him... and each person under him can have n people under him, etc. This is a tree structure and is represented in database books as a common example as a single table Employee.

  • No pre-built ActionBar for Android pre-3.0?

    - by Ollie C
    I note the release a few days ago of the static library bringing fragments to Android versions prior to 3.0, but does this library include the ActionBar? I suspect not. I assume that for an app that will work on pre-3.0 versions, that it needs a hand-built ActionBar implementation for versions up to 2.3 and then to use the OS default ActionBar in v3.0? for some reason I assumed the library had ActionBar in it, but as I dig further I'm not finding any evidence of its presence.

  • How do I update the system wallpaper in an Android 1.6 service after changing it with setWallpaper()

    - by Majakk
    So basically the code "almost" works - the problem is that the system does not appear to know that the system wallpaper have been changed or does not do anything about it. Starting and closing another app manually appears to enforce an update. In an event call the following is done: getApplicationContext().setWallpaper(pWallOne); Is there some way of telling the android system to update the graphics or to do some cheap trick that forces it to? Any help or tip would be very much appreciated!!

  • How to parse responses from a Django server in android?

    - by primal
    Hi, In the Android application I am building, I want to be able to communicate with a local server developed in Django. (Basically a login page and a home page populated with posts and images from users) So do I need to use XML Parsers for the parsing the response from a Django server or is it possible for the server to respond with strings which can be directly used? Also what about images? Regards, Primal

  • How do I delete all tables in a database using SqlCommand?

    - by mafutrct
    Unlike the other posts about the task "delete all tables", this question is specifically about using SqlCommand to access the database. A coworker is facing the problem that no matter how it attempts it, he can't delete all tables from a database via SqlCommand. He states that he can't perform such action as long as there is an active connection - the connection by the SqlCommand itself. I believe this should be possible and easy, but I don't have much of a clue about databases so I came here to ask. It would be awesome if you could provide a short code example in C# (or any .NET language, for that matter). If you require additional information, just leave a comment.

  • How do you manage your sqlserver database projects for new builds and migrations?

    - by Rory
    How do you manage your sql server database build/deploy/migrate for visual studio projects? We have a product that includes a reasonable database part (~100 tables, ~500 procs/functions/views), so we need to be able to deploy new databases of the current version as well as upgrade older databases up to the current version. Currently we maintain separate scripts for creation of new databases and migration between versions. Clearly not ideal, but how is anyone else dealing with this? This is complicated for us by having many customers who each have their own db instance, rather than say just having dev/test/live instances on our own web servers, but the processes around managing dev/test/live for others must be similar.
