QUESTION
Hello guys, I deleted 4 sql files from flyway and the corresponding schema version rows from the database, It's an spring mvc project. I tried to rollback all the files but nothing changed. I am using intellij. Any ideas how can I solve this?
...ANSWER
Answered 2020-Dec-22 at 11:43The error means that Flyway can see a migration file (V0.1.10) which isn't the latest - that is, there are higher numbered migrations in the history table - but is has no record of applying it in the past and it's not explicitly being ignored. The quick workround is to add the config flag -ignoreIgnoredMigrations=true
As a matter of principle, though, you should not delete migration files and alter the history table. Once you've done that, there is both the possibility of errors if you introduce a mismatch anywhere, and you've also broken the idea that the collection of scripts (source controlled, hopefully!) allows you to faithfully reproduce the database state with flyway clean migrate

I've created a Template Literal that displays information about a product. Open the collapse, and click a button to display a modal for additional information.
I'm passing strings of text to output to a ul
within the modal. If a string is empty, it's displaying an output of "undefined".
If a string is empty, how do I not display that li
at all?

I'm passing several pieces of data through an array, and outputting the HTML through a div tag.
There is potential for two events to be displayed in the array. But, if I don't have any data for the second one, it will still display the icons.
What I'm trying to do is to hide that row if nothing is contained that part of the object.
I can't figure it out.
...ANSWER
Answered 2019-Jul-05 at 09:27It's better you add the event data as array
. Then you can easily loop through it and on each loop you can check if there is value is defined or not.
Now here is just checking in your existing code. It's not a good method for dynamic data. Better you build like a tree array.

I use generally xml configuration in my Spring project under the three files:

QUESTION
I use hibernate 3 , spring version: 3.0.0.RC3 and I use postgreSql 9.3
I used c3p0-0.9.1.1.jar and postgresql-9.4.1208.jre6.jar
I have a connection loss problem.
this is the error :
...ANSWER
Answered 2018-Mar-09 at 20:43Too late an answer, but let's see how it goes (or went).
why is
maxConnectionAge
set to 10? It's too short. By the way, it's in seconds, not hours. What it means is that even if and when your connection is not idle, it can only live up to 10 seconds. That's mass killing of your application.maxIdleTime
could be increased from the current 180 seconds to say an hour or even higher. The point of using a connection pooling is to reduce the creation/destruction of underlying DB connections so frequently.Though this is not related to the timeout issue you had,
maxStatements
could be increased as well. If your app is constantly polling a DB table for changes or updating it as and when new entries occur, this could come handy.
