<template>
<!--
if this component is shown, either the user is an admin (can do a merge without checks), or they are a writer who has the permission to do a merge
if the user is a writer and can't do a merge now (canMergeNow==false), then only show the Auto Merge for them
How to test the UI manually:
* Method 1: manually set some variables in pull.tmpl, eg: {{$notAllOverridableChecksOk = true}} {{$canMergeNow = false}}
* Method 2: make a protected branch, then set state=pending/success :
curl -X POST ${root_url}/api/v1/repos/${owner}/${repo}/statuses/${sha} \
-H "accept: application/json" -H "authorization: Basic $base64_auth" -H "Content-Type: application/json" \
-d '{"context": "test/context", "description": "description", "state": "${state}", "target_url": "http://localhost"}'
