+================================
|
|
|
|
|
+
|
|
|
|
|
+Here we try to answer some common questions and pitfalls about FlaskBB.
|
|
|
|
|
+
|
|
|
|
|
+* Why do I get a ``AttributeError: 'NullTranslations' object has no attribute 'add'`` exception?
|
|
|
|
|
+
|
|
|
|
|
+ This usually happens when you forgot to compile the translations.
|
|
|
|
|
+ To compile them, just run::
|
|
|
|
|
+
|
|
|
|
|
+ $ flaskbb translations compile

|
|
|
|
|
+* Why isn't the cache (Flask-Caching) using the configured ``REDIS_URL``?
|
|
|
|
|
+
|
|
|
|
|
+ You have to set the ``CACHE_REDIS_HOST`` to the ``REDIS_URL``. This is
|
|
|
|
|
+ inconvenience is caused because you are not limited to redis as the caching
|
|
|
|
|
+ backend. See the
|
|
|
|
|
+ `Flask-Caching <https://pythonhosted.org/Flask-Caching/#configuring-flask-caching>`_
|
|
|
|
|
+ documentation for a full list of caching backends.
