Hi I am a new member in stackoverflow. I am currently using sqlAlchemy in flask. Trying to get the matched categories of string provided with the search url. The code of search url is given below:
@productapi.route("/search/category", methods=["GET"])
def search_category():
category_param_value = request.args.get('querystr', None)
print(category_param_value)
if category_param_value is None:
return jsonify(message='Which category you want to search????'), 400
try:
category = Category.query.filter_by(
title=Category.title.like("category_param_value %"))
except SQLAlchemyError as err:
return jsonify(message='Category not found.'), 400
category_list = category_schema.dumps(category)
return category_list.data, 200
I tried with httpie with following url: http get http://192.168.1.98:5000/api/v1/search/category?querystr="test"
Error:
sqlalchemy.exc.ProgrammingError: (psycopg2.ProgrammingError) operator does not exist: character varying = boolean
Hoping for a positive response. Thank You.
You are not using the correct syntax. Also you should format the string you are passing to like
.
Change this line:
category = Category.query.filter_by(title=Category.title.like("category_param_value %"))
to this:
category = Category.query.filter(Category.title.like(category_param_value + "%")).all()
