您好我是stackoverflow的新成员。我目前正在烧瓶中使用sqlAlchemy。尝试获取搜索网址提供的匹配类别的字符串。搜索网址的代码如下:
class Example:
def __init__(self, parameter):
if parameter == 0:
# trivial case, the result is always zero
self.calc = lambda x: 0.0 # <== replacing a method
self._parameter = parameter
def calc(self, x):
# ... long calculation of result ...
return result
我尝试使用httpie跟随以下网址:http get http://192.168.1.98:5000/api/v1/search/category?querystr=&#34; test&#34;
错误:
@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
希望得到积极的回应。谢谢。

您没有使用正确的语法。您还应该将要传递的字符串格式化为like
。
更改此行:
category = Category.query.filter_by(title=Category.title.like("category_param_value %"))
到此:
category = Category.query.filter(Category.title.like(category_param_value + "%")).all()
