Change Max Length Enum - Link fields

[Falerci]

Hi there,

I would like the change the Max Length in some fields.

In a Varchar field, Espo gives the possibility to change the Max Length. - Check attached Photo


For fields like Enum and Link, I don't have the possibility to change the Length. It goes directly to 255. - Check attached Photo


Do you know a way to change the fields Length?

Thanks in advance.

Hi,
You cannot do it via UI, so you need to define the "maxLength" length parameter in a correspondent JSON file in the
/custom/Espo/Custom/Resources/metadata/entityDefs directory. For example, add this code to the desired field's parameters:

"maxLength": 100,

The system can automatically increase this parameter in DB, but not decrease it. So after you set the "maxLength" in a .json file, you need to open your DB and change the length of this column manually to 100 as well. Make rebuild in the end.
