Configuration Parameters

exempt_models

Default: [] (empty list)

A list of models provided by other plugins which should be exempt from branching support. (Only models which support change logging need be listed; all other models are ineligible for branching support.)

Warning

A model may not be exempted from branching support if it has one or more relationships to models for which branching is supported. Branching must be supported consistently for all inter-related models; otherwise, data corruption can occur. Configure this setting only if you have a specific need to disable branching for certain models provided by plugins.

Models must be specified by app label and model name, as such:

exempt_models = (
    'my_plugin.foo',
    'my_plugin.bar',
)

It is also possible to exclude all models from within a plugin by substituting an asterisk (*) for the model name:

exempt_models = (
    'my_plugin.*',
)

---

max_working_branches

Default: None

The maximum number of operational branches that can exist simultaneously. This count excludes branches which have been merged or archived.

---

max_branches

Default: None

The maximum total number of branches that can exist simultaneously, including merged branches that have not been deleted. It may be desirable to limit the total number of provisioned branches to safeguard against excessive database size.

---

schema_prefix

Default: branch_

The string to prefix to the unique branch ID when provisioning the PostgreSQL schema for a branch. Per the PostgreSQL documentation, this string must begin with a letter or underscore.

Note that a valid prefix is required, as the randomly-generated branch ID alone may begin with a digit, which would not qualify as a valid schema name.
