I’m working on a preview feature in my backend module and I need to reuse templates from the frontend to avoid having duplicate code. Right now I’m trying something like this:
The problem is that since I’m running this from the backend context, I’m worried about how the partials inside that template will work. Will the routing system and other frontend-specific components function correctly when called from backend? What’s the best approach to handle cross-context template usage in Symfony without breaking the application flow or creating maintenance headaches?
You’re right to worry about this. Cross-context templates will break when your frontend tries to use routing, helpers, or config that doesn’t exist in the backend. I’ve hit this wall before. Best fix I’ve found: build a separate service that handles template rendering outside both contexts. Pull your template logic into neutral helper methods and pass all data explicitly instead of relying on global variables. Alternatively, I’ve had success with a wrapper method that temporarily switches application context during rendering. Just make sure you clean up properly or you’ll get weird side effects.
for sure! Mixing contexts can lead to issues with assets and helpers. Setting up a shared directory like lib/templates/ or using a service to manage context is much smoother! Avoids craziness with routed links and keeps things tidy.
Interesting challenge! What happens with frontend routing when those partials generate URLs? Are you using the same data structure for both, or do you need to transform it for the preview?
