Question

对于某些课程，我在尝试添加作业或使用以下堆栈跟踪打开成绩簿时收到dmlwriteexception：

Debug info: Column 'grademax' cannot be null
INSERT INTO mdl_grade_items (courseid,categoryid,itemname,itemtype,itemmodule,iteminstance,itemnumber,iteminfo,idnumber,calculation,gradetype,grademax,grademin,scaleid,outcomeid,gradepass,multfactor,plusfactor,aggregationcoef,aggregationcoef2,sortorder,display,decimals,locked,locktime,needsupdate,weightoverride,timecreated,timemodified,hidden) VALUES(?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?)

在所有课程中都没有，我在CentOS上使用Moodle 3.1。

请问，我该如何纠正？

Answer 1

您正尝试在数组中插入null（索引11：grademax）。该计划不喜欢这个。很可能这不是可以为空的字段，可能用于某种类型的计算（平均值？）。我不确定该领域的内容，似乎是班级中的最高等级或最高分数。该字段需要一个值。好像它应该是数字。

Answer 2

问题似乎是进入非可空字段（grademax）的空条目。稍后在堆栈转储中，它提到$ requiremodintro和$ gradepointdefault作为未定义的属性，这可能是由于在插入之前未加载的配置文件。
