Hi I am pretty new to wicket but I have been looking around for an example that show's how I can get data from a table in my database and then edit that data on a grid view in wicket and the changes being saved back to my database.
As you can see I tried doing it this way but it looks pretty bad and not very user friendly if the user has to go click edit every time to make a small change is there perhaps a better way to do this?
My goal is to make a time sheet where users will receive there specific time sheet when logging in and be able to edit is as they please like a excel time sheet almost.
Take a look at the 'library' example:
http://examples7x.wicket.apache.org/library/
Wicket is HTML presentation library. The buttons and form submits done in the wicket forms will trigger the logic that will modify your base.
You need a data access technology for this, its can be:
- an ORM like hibernate,
- a SQL generation library like JOOQs
- or you can write directly you hown SQL and pas it to database JDBC connection...

I'm using CasperJS for automated UI tests. I've done the basic UI testing and validation with some random data, kind of POC. I've set up this automation using bash script which kicks to start the web server, load MySQL data from SQL file, start CasperJS test cases, stop the web server, check the log files.
Now, I want to start the testing with some good known status of data which are stored in MySQL. So that I can test the list data and form data with detailed field information with some known database status. How should I know the status of data in the database at a moment?
1) Should I use pre-populated JSON dumped file which has status and details about all data?
2) Should I use web service API? (web service APIs are being used to show/save/delete data from the web page)
Let's take an example. I've 5 users in Users table. Now when I open the home page it shows 5 users with some rough details. When I click on any record from the list of users, it shows a form with detailed information about that user. The webpage is requesting to the web application to get the detail about a user with the help of user_id to show the detailed user data in a form. Now I want to check that all the data in that form is populated correctly. So at the next step, what would be the preferred way, should I read content from JSON dumped file or should I use web service API (like webpage does).
Searching this problem online, I also found MYSQL HTTP plugin. Should I consider this as well? and How safe it is to use? (I know from the docs that this plugin is not for the production, it is just for testing purpose only. :) )
For the main question in cases like this I would change the database connection string to your testing database (this is a clone).
In your case use your bash script to change the connection string (file copy?) automatically before you run the tests. And when completed change back.
Your testing database is a direct clone of your dev/live databsae but with ONLY the test data you want. Downside is you need to keep the schema in sync with DEV/LIVE.
Also another point to take into considertion is if your testing changes state (post). If so your testing data might be out of sync. One way is get around this is to drop foreign keys, truncate the data and load in a dump file.

I am beginner in DNN. I am creating a module which provides Login, Dashboard and Add-Update Form. I have data in JSON format. I want to store it temparory while user use the website. Data will be destroy as soon as user will close the website.
Currently I have created a folder in my Solution Explorer of project in Visual Basic and created 3 .json files which stores login_info.json, basic_info.json and auth_info.json. I write json data whenever user login and I make it blank when user logout.
Above method is working fine now but I afraid it will work when I will publish this module.
Also I may have situation where I need to store image some where. I don't know how I will manage.
Can anybody please guide me?
Is this proper way to store data temparory in DNN?
Is there any other better way?
After getting one of reply for Database Suggestion
Is there any table which same as User Meta in DotnetNuke?
You use the ConnectionString that is used by DNN and access the database as you would normally.
DotNetNuke.Common.Utilities.Config.GetConnectionString()
Or you can use the Data Access Layer that the DNN Framework supplies. For that take the Christoc Templates. In there is all you need to communicate with the DB.
I have the following problem:
I Am using a Django framework.
One of the parts in a system (non-django) writes to the database, in the same database that django is using.
I want to have a signal when an object is being saved. It's a django model object but not saved via django, but directly in the mysql database.
Is there a way django can watch save-actions in his database when it's not being saved by django?
The neatest way would be: create an Api, and let the save action run through this api. The save signal can than be django default. (but this depends on some work of externals... so not the prefered route... for future development it sure is).
Another option is to implement celery and create a task that frequently looks whether one of the saved objects has had no follow up..... (also quit some puzzling I guess to get this up and running)
But there might be an easier... for me unknown?
I saw django watchdog solutions for file systems... not for databases (probably because django has this build in... when properly done through django)
to complex it: I test and develop locally with sqlite .... but the save signal I can put in my tests without needing to get this locally working.... as long as it works in mysql, I Am happy.
You can try this solution:
Create a new table 'django_watch' with one column 'object_id' (add other columns like 'created_datetime' etc according to your standards);
Lets say your main table is 'object'. Add a mysql trigger for the INSERT event on this table.
You should add an extra insert query inside the trigger to insert the object_id into 'django_watch' table.
Now you can have a cronjob that will be inpecting the new table 'django_watch' (for updations in Django objects) and perform necessary actions. You can run this cronjob continuously with some 1 minute delay (upto you).
In the end, I wrote an api that can be called by the thirdparty module. I delivered the code to logon on django using c-code to this api and call the GET of this api. (using django rest framework). This api just saves the object (the id given in the url), and from there on it's default django. The only thing the third party had to do is build in my code to call the api as well....
Maybe not the best solution, but the best to implement for my problem....
I am trying to customize the source files of a Joomla component.
Before the Joomla MVC model introduced, I was able to run SQL queries in a component, Kunena 1.0 to select data from another component. e.g Sobi2.
However, after Kunena 1.5 [MVC model] was introduced, I do not know how / where to add the SQL query to select data from Sobi2.
I believe I need to add some codes in the files of the /models/ or /func/ folder. But can someone provide more detailed assistance on how I can achieve this?
The data interaction is done by the model, you will find Kunena models in the model folder.
Querying the SOBI2 databse is the same as before, MVC wouldn't actually affect how you do this.
To get your head around MVC, have a look at:
http://docs.joomla.org/Developing_a_Model-View-Controller_Component_-_Part_1
For examples of how to query the database in your model, look at:
http://docs.joomla.org/How_to_use_the_database_classes_in_your_script
In simple terms, the Controller directs to the appropriate view (view.html.php), this view then interacts with the model, and then directs to a template file (normally located in the view/tmpl folder.
Hope this helps.
I have Mysql and Zope talking to each other nicely.
I can insert values in, and even view one record from the databse and have it show up in the form fields(not that cool really).
I have just been following tutorials, but now I need to search the Database and display the results.
I have been fiddling with this for a while but I haven't gotten far.
I know that using a Zope Page template we can call the Zsql method and show the results with TAL, but I need to some how using a script and a redirect form the search form pass the search data.
Can anyone help we get started?
Can anyone show me a way to do it with formgen and a custom script adapter?
Go into your ZMI, and add a "Z Search Interface" object in the same folder as your ZSQL method. Your ZSQL methods should show as "searchable objects". Select the ZSQL method you want, fill in the rest of the fields, and it will generate form and display page templates. Then modify the templates to taste.
