Django - show loading message during long processing

由 |▌冷眼眸甩不掉的悲伤 提交于 2019-12-28 04:04:07
问题 How can I show a please wait loading message from a django view? I have a Django view that takes significant time to perform calculations on a large dataset. While the process loads, I would like to present the user with a feedback message e.g.: spinning loading animated gif or similar. 回答1: After trying the two different approaches suggested by Brandon and Murat, Brandon's suggestion proved the most successful. Create a wrapper template that includes the javascript from http://djangosnippets

Loading screen in classic ASP page

由 流过昼夜 提交于 2019-12-25 11:09:40
问题 I have a legacy classic ASP page that is taking a long time to load. This is because before loading it must run a large number of database queries. Load time is upwards of 10 seconds. The page structure looks like this: <% SQL Queries %> <html>...Display the data from the queries..</html> ie, all the queries occur before the markup renders. Due to the long load times I want to create a loading screen that will run before the queries start and close when the queries end, to provide an

Ajax call to return a task status? ( in progress OR finished)

由 寵の児 提交于 2019-12-25 06:57:19
问题 I have a html table with tasks and the last column is called "status". I need to do a simple thing, to track the status of each task with the usual way of an animating gif icon if its in progress or an ok check if its done. I have done this in the past by calling a php script with $.ajax that it was refreshing itself every 1 minute. The script was a PHP script with one query that checked a boolean column. This approach was ok, but even then I knew that this was most probably the dumbest way

Accessing resources inside a JAR [duplicate]

问题 This question already has answers here : How do I read a resource file from a Java jar file? (9 answers) Closed 2 years ago . I'm making a test program for resource loading inside a jar and I'm having problems. I've read that you should use ClassLoader or alternatively getClass() to access a file inside a jar. Since the method that i use to load the resource is static, I use ClassLoader.getSystemResource(String path) . My program finds the file but says that the path contains invalid syntax
