[ethanstrominger]

Dependencies

• 1-M: Asset Group >- (Primary) Tool #81

Overview

As a user when I look at the tools associated with an asset group, I want to see the primary tool included

Action Items

See Resources below

• Add logic so when an asset group is created the primary tool will be added to asset group tools
• Modify logic to do the same when updating an asset group

How to Manually Verify

1. From the asset group screen, create an asset group with a primary tool
2. Review the list of tools on the asset group screen. It should include the primary tool
3. Update the asset group to refer to a different tool.
4. Review the list of tools on the asset group screen. Two tools should be listed.
5. Try to remove the tool from the asset group that was added in step 3. System should prevent you.
6. Remove the tool from the asset group that was added in step 1. This should be sucssessful.

You can achieve this functionality in Django using signals, specifically the post_save signal. (Put this in a file called signals.py in models directory)

@receiver(post_save, sender=AssetGroup)
def add_primary_tool_to_asset_group_tool(sender, instance, created, **kwargs):
    if created or 'primary_tool' in kwargs['update_fields']:
        primary_tool = instance.primary_tool
        if primary_tool:
            AssetGroupTool.objects.get_or_create(asset_group=instance, tool=primary_tool)

In this code:

• @receiver(post_save, sender=AssetGroup) is a decorator that connects the signal handler function (add_primary_tool_to_asset_group_tool) to the post_save signal for the AssetGroup model.
• The add_primary_tool_to_asset_group_tool function checks if a new AssetGroup instance is created or if the primary_tool field is updated. If either condition is met and a primary tool is selected (primary_tool is not None), it adds that tool to the AssetGroupTool table associated with the AssetGroup.

Make sure to register the signal handler in your Django app's apps.py or any other appropriate place to ensure that Django recognizes it during startup. For Knowledge base app you would add following code to class KnowledgebaseConfig:

    def ready(self):
        import knowledgeable.models.signals  

With these changes, whenever you create or update an AssetGroup instance with a primary tool selected, the corresponding entry will automatically be added to the AssetGroupTool table.
