I'm using spring data REST with PagingAndSortingRepository to serve a table, when i download it using pagination, i find the same row present in two different pages, the problem occurs for several rows.
Downloaded data should be inserted in a database with unique constraint, so rows must be unique.
i've added the sort parameter for id column then the duplicates disappears.

While updating data from form to grid, same time two rowid get updated with the same id.
avoided refreshing the grid
when I filter the record adding duplicated records in the grid.
The rowis's in jqGrid should be unique and there should be no duplicated ids. Any duplication of row id's will cause unexpected results like described from you.
I'm using Backpack 3.5 for laravel 5.7, I have two tables related by 1-n. I need to show rows from first table sorted by column in related table, how can this be done?
For sorting in the first table there is a method
$this->crud->orderBy('column', 'order'); but it doesn't work for other related columns
JDev 11.1.1.5.0
Use case:
Display a table where the first row will contain values from one POJO Bean data control and the second row will contain values from another.
I have managed to display the first row from one bean data control, now I want to show the second row with the other.
Hope the use case is clear.
Have a pojo that returns a collection that combines the data from the two pojos into a single record/object.
Then create a table where you put two fields in each column and show the details of the record that way.
I have created a web site using mvc 3 and Ef code first , now after publishing the site and it's DB I have found out that I need to add a new columns to one of my DB table,
(the DB already has a lot of data in it )
should I add the columns direct to the DB or should I add to the class?
(just a simple string with get and set)
And how can I do it without losing my data in the DB ?
thanks
Adding the columns to the class should be enough. Evidence you can find here.
Here is the full list of changes that migrations can take care of automatically:
Adding a property or class
Nullable columns will be assigned a value of null for any existing rows of data
Non-Nullable columns will be assigned the CLR default for the given data type for any existing rows of data
Renaming a property or class
See ‘Renaming Properties & Classes’ for the additional steps required here
Renaming an underlying column/table without renaming the property/class
(Using data annotations or the fluent API)
Migrations can automatically detect these renames without additional input
Removing a property
See ‘Automatic Migrations with Data Loss’ section for more information
I suggest you to add the columns direct to the DB and to the class, and test it on the local machine.
I've a problem with JPA EclipseLink.
I've two functions: First, it inserts a row in the database correctly.
The second reads all the values in the same table and show them to you. The problem is that it shows all the values except the last quote, in order to make this appear, I must close and reopen the application.
I also tried to disable the cache does not work.
Do you have any idea on how to solve?
Thanks
How are you querying the quotes? Are you accessing a OneToMany, or using a query?
If accessing a OneToMany, then it could be a caching issues, which you can disable to check,
http://wiki.eclipse.org/EclipseLink/FAQ/How_to_disable_the_shared_cache%3F
A query should always get all objects from the database. Ensure you committed the inserted objects.
The refresh a specific query see,
