I’m currently working on a project created by someone else. I have a textfield called “city”. Currently the maximum limit is 255 characters. I want to update the maximum character to be 100. Looking at the code, it looks like the field was created using the features module. When I try to update the field, I got the FieldUpdateForbiddenException. I understand this is because I have value in the database. Is there a way update the field even if there is value in there? If I can’t modify the database, can I change textfield max length in the form to be 100?

Thanks!

The website doesn’t have CCK, so I’m not sure how to modify these fields. I’m using Drupal 7.

What I did: 1. I upgraded registration_page.info to upgrade the version from 7.x-1.0 to 7.x-1.1 2. I changed the field max length to 100 in registration.features.field.info

When I tried to deploy, I got this error

  [sshexec] WD php: FieldUpdateForbiddenException: field_sql_storage cannot          [error]   [sshexec] change the schema for an existing field with data. in   [sshexec] field_sql_storage_field_update_forbid() (line 229 of   [sshexec] /var/lib/www.mine.com/deploys/site_20140515_140323/modules/field/modules/field_sql_storage/field_sql_storage.module).

This is what the code look like in registration.features.field.info
