Create a new protected branches shared view

Problem description

As described in the parent epic &8679 Users want to be able to have standardized workflows across teams and projects and leverage protected branches as a way to do this.

Implementation plan

• Copy the existing EE project settings to a new section for EE groups
• Move the shared protected_branches files to a new shared location for projects and groups
• Update the shared edit form and other partials to accept variables so that it can also be used for groups.
  • Make sure the data URL is also using the groups protected branch path too.
  • It might make sense to break this form into group/project files rather than having if checks.
• Replace text Branch was deleted with Branch does not exist in protected branch partial .
• Update specs.

Note

Can be developed in parallel with the backend
