With Django admin, you can create one quickly and flexibly.ĭjango has a powerful ORM which works with all major databases out of the box. I believe every application requires an admin panel-if not yet, it’s simply a matter of time until your basic application needs one. Through the Admin interface, a user can configure a lot of things including the access control list (ACL), row-level permissions and actions, filters, orders, widgets, forms, extra URL helpers, and anything else you can imagine. Django allows you to do all this without compromising on flexibility.ĭjango’s killer feature is a powerful configurable admin interface which builds automatically (automagically?) from your models’ schema and admin panel models, making you feel like a wizard. For me personally, the Admin, Object Relational Mapping tool (ORM), Routing, and Templating features made Django my first choice because applications require a lot of work and, while I enjoy my job as much as any developer could, I want to spend as little time as possible on these basic repetitive tasks. Django has a lot of modern features out of the box. This tutorial is useful even if you’re a skilled Django developer because mistakes, like maintaining an unmanageably large settings or naming conflicts in static assets, aren’t just limited to new developers taking their first stab at Django.ĭjango is a free and open source Python web framework that helpfully solves common development challenges and allows you build flexible, well-structured applications. Any of these mistakes could leave the code "hanging" for lack of a proper reference point to wave, because that wave will not really exist at run time or it will exist somewhere in some location that is not the current data folder or it will not even be defined in the right way even when it does exist where it is supposed to exist.In this tutorial, we will look at some common mistakes that are often made by Django developers and ways to avoid them. This is confusing at best and potentially damage prone at worse. Also, your Pulse code plays jostles around with "$" references to strings as wave names. This means, they are basically non-existent references. * Observations: Your panel/graph display code has no definitions for the "$" waves that are to be displayed in the graphs. Graphs must operate independently of a panel anyway (as you have now learned). * Suggestion: Display your graphs separately and debug their operation BEFORE you embed them in a panel. Secondly, as for the question about updating graph displays, I have a suggestion and some observations. They are only there when the panel is being generated in a "one-step-at-a-time" approach as per a command line entree. * Correspondingly remove all the unnecessary PauseUpdate, DelayUpdate, and Silent 1 commands in the ShowPulseInfoPanel() function. * Replace the Window PulseInfo() with a function call that is a bit more understandable, e.g. * Put return values at the end of the Functions (e.g. These references to folders will help keep the code "transportable" as you move from one folder to another or one experiment to another and accidentally change the location of the current data folder. * Learn to use DataFolderDFR functions to set or define locations of waves. I believe Macros are mostly considered obsolete except for backward compatibility. Wide-Angle Neutron Spin Echo Spectroscopy.
