I am trying to make a blog post web application using firebase. Each post will display name and profile image of at the top bar/header of post.

But due to media-token associated with each profile image file uploaded on Storage is unique. if a user update their profile pic then on blog post profile image doesn't load and show 'ERROR: 403' in console.

How we can manage to show user profile image and their name along with every post? For example you can consider wall post of facebook.

If you store the profile image URL with each blog post, you will have to update each blog post when a user's profile image URL changes. For a few strategies on how to do that, see: How to write denormalized data in Firebase. While these are for the Firebase Realtime Database, the same approaches apply to Cloud Firestore.

Alternatively, you can only store a user's profile image URL in their own user document, and then look it up when displaying a blog post from that user. In that case you would only have to update the URL in the user's own document.

  • Hey Frank, I am already storing user's profile data(Name, ID, Profile IMG) in firebase realtime database and blogs I am storing in Firestore Database. If I do lookup for every post done by multiple users then query may takes time to fetch for profile image urls – Prashant Kumar Oct 12 '20 at 15:55
  • Is there any way to ignore media token associated with each image, if can ignore then my problem would be solved. :) – Prashant Kumar Oct 12 '20 at 16:10
  • You can set public access on the bucket, which would remove the need for a token and allows anyone to access files in that bucket. That's a Cloud Storage setting, outside of the scope of Firebase, so I'd recommend checking the Google Cloud Storage docs for how to do it. – Frank van Puffelen Oct 12 '20 at 22:05
