column-aggregation

问题 Has anyone noticed this? Whenever a model uses column_aggregation (inheritance), the schema.sql has 2 CREATE TABLE commands, one creates the basic table, and the other (apart from fields) adds an index on the inheritence column CREATE TABLE Prop (id INT AUTO_INCREMENT, opt_property_type SMALLINT UNSIGNED DEFAULT 251 NOT NULL, property_nature VARCHAR(255), INDEX opt_property_type_idx (opt_property_type), PRIMARY KEY(id)) DEFAULT CHARACTER SET utf8 COLLATE utf8_unicode_ci ENGINE = InnoDB;

问题 i am using jqgrid with the treegrid view and most of the columns are numbers that are aggregated up the tree. The one missing piece is having a total row to aggregate the top level hierarchy. Is there something built into jqgrid to support this or should be passed down the: 回答1: Tree grid support footer row (see the second picture here) for tree grid in the same way like for the standard grid. If you calculate the content of the summary row on the server you can use userdata in the JSON input
