Images are not updating in the browser after they are changed in the database

Question

A User has a photo. When they update their photo, it is successfully updating in the database however it does not update in the browser. If I open a different browser, I can see that it has been updated. But this problem is occurring in all browsers. Is there any way that I can force Rails to show the new image after it is updated?

I am using standard code in the controller that updates the user_params.

From Heroku Console

Started PATCH "/community/8" for
Processing by UsersController#update as HTML
Parameters: {"utf8"=>"✓", "authenticity_token"=>"7zUIz7zxmYm8dssdSEGDHbddsieyVnwix8z/Fx/sxVzXqoLtxNq+3sxfps8RsE6pV/XN5V46qhJdo1VpKLK8pF3wDmZNg==", "user"=>{"profile"=>"Cool dude. Lives under ocean.", "photo"=>#, @original_filename="som-tam-thai.jpg", @content_type="image/jpeg", @headers="Content-Disposition: form-data; name=\"user[photo]\"; filename=\"som-tam-thai.jpg\"\r\nContent-Type: image/jpeg\r\n">, "gender_type"=>"male", "country"=>"US"}, "id"=>"8"}
[1m[35mSQL (1.5ms)[0m UPDATE "users" SET "photo" = $1, "updated_at" = $2 WHERE "users"."id" = $3 [["photo", "8.jpg"], ["updated_at", "2017-03-04 18:34:20.835477"], ["id", 8]]

If I update the other user attributes that are strings, they will be shown immediately. Only the photo requires that the browser be restarted for the changes to be shown.

can you show your code snipped for rails server and client side — user3775217

To see the new, updated image, you need to use redirect_to method. It should redirect to profile of user with this particular id.

def edit
  @user = User.find(params[:id])
end

def update
  @user = User.find(params[:id])

  if @user.update(user_params)
    redirect_to @user
  else
    render 'edit'
  end
end
