In quarkus 2.9.2.Final I try to configure flyway placeholders in src/test/resources/application.properties by
quarkus.flyway.placeholders.a=a
quarkus.flyway.placeholders.b=b
where in the flyway script these placeholder are used like
create user ${a} with password '${b}';
However, when I run the test which starts up db and executes flyway I get error
Caused by: org.flywaydb.core.api.FlywayException: No value provided for placeholder: ${a}. Check your configuration!

I checked that my config is valid by defining a config mapping
#ConfigMapping(prefix = "quarkus.flyway")
interface MyConfig {
Map<String,String> placeholders();
}
and injecting it in a service where the Map was exactly having these two elements.
So now I really wonder why flyway quarkus extension cannot handle it / which trick I am missing.
Please help, I need this simple thing to work.
Oh no I found it..small but IMO nasty one driving me crazy.
In my project, Flyway is only to be used with my named datasource 'myds'.
So config had to be changed to:
quarkus.flyway.myds.placeholders.a=a
quarkus.flyway.myds.placeholders.b=b
Would be nice to have an error message which gives a clue. But maybe it's only my fault, so I guess not worth asking for improvement in flyway.

I am working on externalizing our IScheduledExecutorService so I can run tasks externally on a external cluster. I am able to write a test and get the Runnable to actually run ONLY if I turn on UserCode deployment. If I want to change this task at all and run the tests again I get the below in my external cluster member's logs..
java.lang.IllegalStateException: Class com.mycompany.task.ScheduledTask is already in local cache and has conflicting byte code representation
I want to be able to change the task if I could and redeploy to Hazelcast to just handle it. I do this kind of thing with our external maps now. It can handle different versions of our objects using compact serialization.
Am I stuck using user code deployment for these functional objects? If I need to make a change to it I need to change the class name and redeploy to production. I'm hoping to get this task right the first time and not have to ever do that but I have a way of handling it if I do.
The cluster is already running in production and I'll have to add the following to each member
HZ_USERCODEDEPLOYMENT_ENABLED=true
and the appropriate client code(listed below) to enable this.
What I've done...
Added the following to my local docker file
HZ_USERCODEDEPLOYMENT_ENABLED=true
and also in the code that creates a hazelcast client connecting to my external cluster with
ClientConfig clientConfig = new ClientConfig(); ClientUserCodeDeploymentConfig clientUserCodeDeploymentConfig = new ClientUserCodeDeploymentConfig(); clientUserCodeDeploymentConfig.addClass("com.mycompany.task.ScheduledTask"); clientUserCodeDeploymentConfig.setEnabled(true); clientConfig.setUserCodeDeploymentConfig(clientUserCodeDeploymentConfig);
However, if I remove those two pieces I get the following Exception with a failing test. It doesn't know about my class at all.
com.hazelcast.nio.serialization.HazelcastSerializationException: java.lang.ClassNotFoundException: com.mycompany.task.ScheduledTask
Side Note:
We are using compact serialization for several maps already and when I try to configure this Runnable task via compact serialization I get the below error. I don't think that's the right approach either.
[Scheduler: myScheduledExecutorService][Partition: 121][Task: 7afe68d5-3185-475f-b375-5a82a7088de3] Exception occurred during run

I have created many models in loopback for my project. And use these models with the help of "http://localhost:3000/explorer" in my browser.
These model API's are working fine. But, whenever I tried to use built-in models i.e "user" from the explorer. I got the below error:
and in the terminal. I got the below error. And terminal command automatically terminates.
I am new in the loopback. Why am I not able to use built-in models "user".
Please, help me.
Thanks in advance.
To anyone else that encounters this, I ran into this today and found this question unanswered, so I will do my best to give my explanation and findings here.
The error, roleModel.isInRole is not a function, means simply that the role model does not have a function called isInRole.
In my case, this was because another model was automatically generated from an existing database table called Role, which overrode the internal Role model of Loopback.
When the internal Role model is overridden, the isInRole function is not inherited automatically and will result in the above error.
I am implementing Munit for a flow which involves Mule Requester. This mule requester would be picking up a file.
So, when i run the java class as Junit, it throws out an exception as, Cannot perform the operation on the FileConnector as it is stopped.
The expression used in mule requester is ,
file ://${path}?connector=FileConnector
I have also defined a global file connector.
Please let me know how to resolve this issue.
Thank you.
All connectors and inbound-endpoints are disabled by default in MUnit. This is to prevent flow accidentally processing/generating real data. (Some explanation here). For the same reason File Connector is also disabled.
To enable connectors, you need to override a method in your MUnitsuite as below -
#Override
protected boolean haveToMockMuleConnectors() {
return false;
}
For XML Munit, see this to enable connectors.
Note: This will enable and start all the connectors that you are using in your mule-configs under test. If you have SMTP connector, DB connector, MQ connector etc, they all be started during test, so use it with caution.
Check whether the file connector is defined in the files you loaded for munit.
<spring:beans>
<spring:import resource="classpath:api.xml"/>
</spring:beans>
You may also try mocking the mule requester.
While working through a tutorial to start learning Grails, I made a mistake and ran:
grails create-domain-class com.FooBar
instead of:
grails create-domain-class com.acme.FooBar
It was immediately obvious I had made an error so I tried the following:
Searched for a function that reverses the create-domain-class command, it seems there isn't one.
Searched for advice on the web and the consensus is that you can delete a domain class file, any associated views and tests, then to be safe run a text search for your class name in your project directory for any references you may have missed. I have done all this.
Then I ran the correct command to create com.acme.FooBar, which worked.
After this the app fails to run and reports the following error:
org.hibernate.DuplicateMappingException: duplicate import: FooBar refers to both com.acme.FooBar and com.FooBar (try using auto-import="false")
After adding the following code to com.acme.FooBar:
...
static mapping = {
autoImport false
}
...
The app now runs as expected.
However as an experienced Java developer who occasionally does refactor a package I would like to understand how to do that without causing a DuplicateMappingException or resorting to the "autoImport false" solution.
Thanks.
You shouldn't be doing
static mapping = {
autoImport false
}
As, by doing this you said that don't check for domain just by name and look up for package as well. Hence, once you do that you will have to use Fully qualified name of the class in your queries / hqls which may itch sometimes.
You should be removing the Domain completely i.e.
remove the Domain
remove the view folder creating by default with very same name and so do the controller
Now, do grails clean-all(Make it a thumb rule to use grails clean-all first for any issue unexpectedly occuring).
To be more accurate do remove target directory from your project and then do run grails run-app.
I had done very same thing many times and got it resolved by above steps.
Hope it helps.
I am working on asp.net mvc with EF code first model. I am trying to apply migrations using EF code first to my project. I am using MySql database. currently i am using EF 4.3.1 version and mysql connector/.net of 6.6.4.0 version. I am successfully add migrations to my project that means i execute series of commands that gave no errors for me. I have followed these steps,
PM> Enable-Migrations
PM> Add-Migration InitialMigration
PM> update-database -verbose
these steps create Migration folder to my project and inside Migration folder it creates configuration and timestamp_Initialmigration files, in configuration file i have added following code.
SetSqlGenerator("MySql.Data.MySqlClient", new MySql.Data.Entity.MySqlMigrationSqlGenerator());
after that i have added one field to my class like,
public int newprop{get; set;}
after that i execute update-database -verbose command in PM console.
when i execute my application it throws an error like,
"Unknown column 'Extent1.newprop' in 'field list'"
please guide me why i am getting this error does i went to the wrong way please guide me.
If your not using automatic migrations
Database.SetInitializer(new MigrateDatabaseToLatestVersion());
public class MyMigrationConfiguration : DbMigrationsConfiguration<MyDbContext>
{
public MyMigrationConfiguration()
{
AutomaticMigrationsEnabled = true; // Are you using this ?????
AutomaticMigrationDataLossAllowed = true;
}
}
Then you need to tell EF using the PM Commandlet to add another migration and update the database.
PM> Enable-Migrations //already done this ?
PM> Add-Migration myLabel
PM> Update-Database
Search for "code based migrations" on web for help
This is a bit late to answer OP... But since it pops up as my first hit on google, ill go ahead anyways :)
The problem here is, that there are a number of restrictions on MySQL as compared to MSSQL.
* In particular with mysql on casesensitive filesystems (linux hosts), table names may not include capitalized letters.
* Also keys are restricted to 767 bytes and should/must be integer types.
* Then there is a problem in parts of the migration generators from Mysql.Data package. For instance when renaming, 'dbo' is not stripped away.
Have a look at this guide on insidemysql.com. It describes how to reconfigure the Aspnet.Identity stack for using int in the TKey typecast.
I have a project where i also have hooked into HistoryContext, allowing to alter structure of __MigrationHistory. It renames and resizes the table/columns. There's also the remake of IdentityConfig - so have a look at
https://github.com/mschr/ASP.NET-MVC5.MySql-Extended-Bootstrap/tree/master/my.ns.entities/DbContexts/MigrationConfig
https://github.com/mschr/ASP.NET-MVC5.MySql-Extended-Bootstrap/tree/master/my.ns.entities/IdentityConfig
Then hook it up with your context (see IdentityDbContext) and enable the mentioned MySqlMigrationScriptGenerator and HistoryContextFactory in your Migrations.Configuration class (see my IdentitiyMigrations.Configuration)
