flasksqlalchemy query multiple parameter with startwith and paginate

i am trying to query multiple parameter with startswith and other parameter and pagination in flask.    

results_of_search = Course.query.filter(Course.title.startswith(search_data)).paginate(per_page=9)

this query is giving me the correct result but i want to add other filters as well results_of_search = Course.query.filter(Course.title.startswith(search_data),university=current_user.uni).paginate(per_page=9)

i have tried searching everywhere

You mixed syntax of filter and filter_by methods. For filter method there should be also model name before attribute name, and you should use ==, instead od =:

Course.query.filter( 
   Course.title.startswith(search_data),
   Course.university == current_user.uni
).paginate(per_page=9)

Here is a topic about differences between filter and filter_by: Difference between filter and filter_by in SQLAlchemy
