在Flask应用中,我有以下ajax调用:
$.ajax({ url: "{{ url_for( 'bookings.get_customer' ) }}", type: "POST", data: nameArray, success: function( resp ){ console.log( resp ) } })
如你所见,我正在传递一个数组,我将在该数组上搜索我的mongo数据库,该数据库将返回或不返回客户。
因此,负责处理此ajax调用的python def是:
@bookings.route( '/get_customer', methods=[ 'POST' ] ) def get_customer(): name = {} for key, value in request.form.items(): name[ key ] = value customer_obj = customer_class.Customer() results = customer_obj.search_customer( name ) return results
为了论证,可以说customer_obj调用返回以下列表:
[{'customer': { u'first_name': u'Dave', u'tel': u'0121212121458', u'country': u'UK', u'address2': u'Townington', u'address3': u'Cityville', u'email': u'dave@smith.com', u'postcode': u'A10 5BC', u'address1': u'10 High Street', u'second_name': u'Smith' }, 'customer_id': u'DaveSmithA10 5BCCat_Vegas1346244086' }]
当我尝试将其返回给ajax调用时
return results
我收到以下错误:
TypeError: 'list' object is not callable
这是回溯:
Traceback (most recent call last): File "/usr/local/lib/python2.7/dist-packages/flask/app.py", line 1701, in __call__ return self.wsgi_app(environ, start_response) File "/usr/local/lib/python2.7/dist-packages/flask/app.py", line 1689, in wsgi_app response = self.make_response(self.handle_exception(e)) File "/usr/local/lib/python2.7/dist-packages/flask/app.py", line 1687, in wsgi_app response = self.full_dispatch_request() File "/usr/local/lib/python2.7/dist-packages/flask/app.py", line 1361, in full_dispatch_request response = self.make_response(rv) File "/usr/local/lib/python2.7/dist-packages/flask/app.py", line 1450, in make_response rv = self.response_class.force_type(rv, request.environ) File "/usr/local/lib/python2.7/dist-packages/werkzeug/wrappers.py", line 711, in force_type response = BaseResponse(*_run_wsgi_app(response, environ)) File "/usr/local/lib/python2.7/dist-packages/werkzeug/test.py", line 818, in run_wsgi_app app_iter = app(environ, start_response) TypeError: 'list' object is not callable
有没有人有什么建议?
Flask不希望你list从视图函数返回对象。尝试jsonify之前:
list
jsonify
from flask import jsonify @bookings.route( '/get_customer', methods=[ 'POST' ] ) def get_customer(): name = {} for key, value in request.form.items(): name[ key ] = value customer_obj = customer_class.Customer() results = customer_obj.search_customer( name ) return jsonify(customers=results)
