  • Generate Model from Database is only generating the first table; is it only me ? For 20 tables I have to start the generator 20 times …
    → it is an additional datastore

    with this table it is generating

and no column’s in the datagrid ;/

→ this might be the reason, it is not proceeding to the other tables …

  • Is it a lot of work to make bigint(20) unsigned a valid PK ?

Best regards

Hi Felix,

Yes, it is very likely that the issue with entity screen generation is caused by an error in Jmix Studio, which prevents entities from being generated for all 20 tables. Normally, generating multiple entities from a database at once should work without any problems.

Unfortunately, we don’t have enough information yet to help you investigate this issue. Please attach the relevant fragment of the IDEA log related to model generation, or the entire idea.log file. Are there any errors in the log?

An SQL script that reproduces the database schema with the problematic table could also help us reproduce the issue on our side.

Regarding your question about supporting bigint(20) unsigned as a valid primary key: if I understand the case correctly, full Java support for this data type requires using BigInteger, which is not supported as an ID type for Jmix entities. Adding support for it is not currently planned.
