Django filter and date formatting Parameters

Reprinted: http://blog.csdn.net/xyp84/article/details/7945094

 

Django1.4

When the HTML page reads the datetimefield field from the database, the displayed time format is different from the format stored in the database. For example, the database field content is 16:00:00, but the page displays Aug. 26,201 2, 4 p. m.

To make the page consistent with that displayed in the database, you need to add <TD >{{ dayrecord. p_time | Date: "Y-m-d h: I: s" }}</TD> similar filter. Refresh the page to display it normally.
