Re: Django-cart. How to run method add_to_cart?

Hi Ricardo, well this is a question that needs a good explanation. I try to give you some hints about what you need to research about: a. You need to send data to the Django server through a POST view. This is a HTTP "verb", that is one of many different ways the browser has to communicate with y

Custom Filter: Filter output based on a Python list

Am working on a Django project that retrieves a student's details from the database, filters them based on the 'period of examination' (this is implemented as a python list in a custom filter) and displays the output. *Here is my custom filter:* @register.filter def periodofexamination(periodof

Re: Best practice for server-generated downloads?

Hi Thomas, I'm doing exactly this - allowing users to download (graphically simple) XLSx files from my web app, it also needs to be available for download weeks later. As Russell pointed out, you don't need to store data on this if you have a way of getting the same set of data later, you can

Re: Custom Filter: Filter output based on a Python list

I'd cycle in the template through a list of exam periods, printing a table for each cycle. You have to pass the list of exam periods in the context of your view. Try and let me know. Regards, Leo Leonardo Giordani Author of The Digital Cat My profile on About.me

Re: Best practice for server-generated downloads?

Hi +1 on this except that I use xlrd and xlwt to read and write Excel files. To generate the excel file I just generate a list of lists (an array effectively) and pass that through a function which walks the list and generates the excel worksheet that I write to a StringIO so it can be returned

model inheritance

Hi, I am extending a 3rd party model in my application, using multi-table inheritance. I can create an instance and modify it, but when I try to list the created objects at http://localhost:8000/en/admin/news/news/ , I am getting a nice exception: Traceback: File "/home/roberto/.virt

Re: Custom Filter: Filter output based on a Python list

Ok, now I get the point. I STRONGLY suggest to avoid performing big computations while rendering templates, so I think it is better for you to try something like def results_page(request): context = {} context.update(locals()) context['periods'] = {} for period in ['DECEMBER 2011',

Hi Leonardo, thanks for your answer. Yes, it has been synced. The model itself is a little bit bigger, as you can notice from the code https://dpaste.de/c3Rg I am using as well the News model from https://github.com/wildfish/cmsplugin_news/blob/master/cmsplugin_news/models.py Regards, Roberto

You can run all of the tutorial stuff in Windows, and it's not a bad idea to learn things one-at-a-time. I would suggest, however, that if you are serious about using django, you need to learn Linux, too. The easiest way to do that would be to download the current Ubuntu desktop version, make

I'm trying to test a Django management command in app X that parses data files and inserts data into models that are located in apps Y and Z. Apps Y and Z have initial_data.json files in them. On running my test however, it seems that my initial_data fixtures are not being loaded. I could specify

is it possible to make the |safe template filter conditional on content

I made a custom template filter (ref_href) which converts numbered references (like [1], [2] etc) into footnote hyperlinks. It works but requires the |safe filter which is dangerous. To be actually safe I want to *only* use the |safe filter when the data contains a numbered reference. Which I
