我在做一个AJAX调用一个python函数。该函数的作用的基础上发送给函数的信息的数据库查询。

我不知道如何获取发送到该函数的变量。

我是用request.vars.variableName了，我知道该函数是有效的，它只是不接受变量正确使用。如何获得职位从一个Python函数发送变量，使用的web2py？

ETA：这是code我用

jQuery.ajax（         {类​​型：POST，         网址：../../Printed/printedballoons/cost.json'，// Python函数         数据：typeSelected，//发送到服务器的数据         数据类型：JSON，         错误：函数（MSG）{$（＃ajaxerror）HTML（味精）;}，         成功：功能（数据）{             balloonPrice = data.cost;         }，         超时：2000}     ）;

该错误是在数据：typeSelected行，与任何数据相关的变量名wasnt，所以蟒蛇查询：

成本= DB（db.balloonprices.type == request.vars.typeSelected）。选择（db.balloonprices.cost）

一直在寻找的，而不是一个东西，实际上是在数据库中。

解决方案

request.post_vars

它们复制到 request.vars 另外，如果没有request.get_vars

I'm making an AJAX call to a python function. That function does a database query based on the information sent to the function.

I can't work out how to get the variable that is sent to the function.

I was using request.vars.variableName, and I know the function is valid, it's just not receiving the variable to use properly. How do I get POST sent variables from a python function, using web2py?

ETA: This is the code I was using

jQuery.ajax( {type: "POST", url: '../../Printed/printedballoons/cost.json', //python function data: typeSelected,//data sent to server dataType: 'json', error: function(msg){$("#ajaxerror").html(msg);}, success: function(data){ balloonPrice = data.cost; }, timeout: 2000} );

The error was in the "data: typeSelected" line, the variable name wasnt associated with any data, so the python query:

cost=db(db.balloonprices.type==request.vars.typeSelected).select(db.balloonprices.cost)

was looking for "" as opposed to a anything that actually is in the database.

解决方案

request.post_vars

They are copied to request.vars also if there is no request.get_vars
