Hi,

I'm currently using the microservice template.

After upgrading to version 7, updates to the translation files are not appearing in the application.

After updating the translation file and starting the application i can see the new changes correctly being added to the AbpLocalizationTexts table. However, when you start the application and it fetches the localizations from "api/abp/application-localization?cultureName=en&onlyDynamics=false" it returns the old version of the file.

Looking in redis it doesn't look like the cache has been updated with the new values.

Am i missing something? Is there something new i need to be doing in v7?

Thanks,

Steve.

    hi

    You can clear the redis and try again.

    Hi,

    That will fix it yes.

    But should it not be updating the cache when it updates the values in the database?

    I don't really want to be wiping my entire redis cache every time i do a deployment that contains a translation update.

    Cheers,

    Steve.

    We can update the cache when you change some things via code, but we can't know anything if you change it in the database.

    Hi,

    I'm not changing anything in the database.

    The database is being updated with the update localisations via one of the ABP packages.

    All i do is update the en.json file in domain.shared.localizations.service directory and then start the microservices. This then gets automatically added to the AbpLocalizationTexts table in the admin service somehow (not via any of my code).

    Cheers,

    Steve.

    hi

    I just checked, the module will clear the relevant cache, what are the detailed steps to reproduce the problem?

    Hi,

    Ok, sounds like it's something with my setup then. Can you let me know what module the code is in? That way i can pull the source code and debug the issue to see what's happening.

    Cheers,

    Steve.

    OK, so tracing this through the system and looking in REDIS the reason why it's not clearing the cache is because it's attempting to remove the wrong key.

    With the redis-cli monitor command you can see that it's running the unlink command and passing it the key c:AbpExternalLocalizationTexts,k:TimeTrackerTimeTrackerService:en

    However, the key in redis is c:AbpExternalLocalizationTexts,k:TimeTracker:TimeTrackerService:en (note the colon between TimeTracker and TimeTrackerService

    It's worth noting that as far as i can tell all the other commands that involve keys being passed to REDIS correctly have a colon between TimeTracker and TimeTrackerService. An example of this is below

    Any ideas?

    Cheers,

    Steve.

    I think I've found the answer to this.

    If we look in the distributed cache class we can see that the cache key is being constructed via the NormalizeKey method that calls KeyNormalizer.NormalizeKey which is method on an injected IDistributedCacheKeyNormalizer

    https://github.com/abpframework/abp/blob/9d2902b335ca089be6ae07242d4470472de39cf5/framework/src/Volo.Abp.Caching/Volo/Abp/Caching/DistributedCache.cs

    Looking at DistributedCacheKeyNormalizer we can see that when it constructs the key it doesn't include a colon

    https://github.com/abpframework/abp/blob/e3e1779de6df5d26f01cdc8e99ac9cbcb3d24d3c/framework/src/Volo.Abp.Caching/Volo/Abp/Caching/DistributedCacheKeyNormalizer.cs

    I ignored this initially because the system seemed to be correctly pulling keys from REDIS without issue.

    However, after some more investigation it looks like all the "templates" for various project types in include a colon when setting KeyPrefix on the AbpDistributedCacheOptions. I added a colon to my KeyPrefix and it all appears to be working correctly now.

    Is what i found correct? Or am i missing something?

    Cheers,

    Steve.

    hi

    Thank you, I will confirm this.

    hi

    The KeyPrefix of AbpDistributedCacheOptions has been set in all template projects, including the microservice template.

    So also recommend you to do this.

    Thanks for checking. My question was more around the need for having the colon character : at the end of the prefix. Is the colon required?

    Cheers,

    Steve.

    I don't think a colon character is required.
