Re: Django vs ExtJS

DJANGO + Tastypie is your TEAM for REST Services, forget Java :)

Given your scenario, we can say that with django, you wouldn't have to worry about creating REST services. You would create only one service, and let django manage the backend switch (with db routers). If you build your service well, you would have an abstract REST view/url generator (tastypie for instance), and with a little bit of effort (REALLY little), you could serialize the resource structure (metadata) on the request, and let ExtJS read that structure to build your frontend. Of course, this aproach requires a little bit of cache (to save some time on the read structure/build html for ExtJS). With that, you would have to write basically only the models (and of course, any exceptional case that might occur). And if you use django 1.7+, you can LITTERALLY forget about db admin, since django handles the migrations as well.

I've done basically the same thing with Django REST Framework and AngularJS for the frontend. Works like a charm, and with the business logic on the signals, reduces the dev time by 90%. And worls like a charm.

Thank you, this is already very helpful.
Currently company policy is to create REST services in java for each backend and use ExtJS to query and visualize the results. With DJango I'm trying to combine these into one, whilst staying compatible by using tastypie as a REST service (so ExtJS can connect to that).

Sincerely, I can't see the ExtJS's Models as true models on an MVC (or MVT for instance) context, since the only real uses I've seen of them is to bind form controls to any "model like" (basically anything) structure. Therefore, the best comparsion for the ExtJS would be AngularJS (this is my point of view, I might be wrong on this one).

But if you REALLY want to compare them, I would say that the biggest point that django excels ExtJS, is that ExtJS doesn't have any meaningfull way to introspect your DB to build the models dynamically, and with django you can. As an exemple, with django, you can build an app that read your DB metadata and build everithing from there (basicaly models; the views and templates you can build in a way that they can read everything on a given standard).

If you provide more specific info about the project, maybe we can come with some more concrete comparsions.

Hi List,

I;m a data maangement specialist in a rather large multinational. I'm trying to push Django as a fast development framework for front-end applications of our databases. Currently the company is focusing on Sencha ExtJS and java solutions. Can you help me with pointers why Django is better? The free-as-in-beer argument is not very convincing by itself.

Thanks

Joris
