Re: Restricting the user from closing the browser tab so that the server side APIs are called.

Rahul, I don't think you're going to find a reliable way to ensure that the APIs are called from the browser.  There are too many ways for the user to close the browser, or for the browser to crash, or for the browser to lose connectivity to the server

ModelFormset Into InlineFormset

I have a class CustomFormSet that inherits from BaseModelFormSet. I would like to have another formset class that does everything CustomFormSet does but instead inherits from BaseInlineFormSet. What is the best pythonic/Django way of doing that? -- You received this message because you are

Re: count from multiple tables in a single query?

Hi James, I'm curious... why dropping down from the ORM and doing a single query wouldn't be portable? I understand that it would happen if you use some kind of stored procedure in the DB, but I guess a single ANSI SQL would do it. Thanks! - Alceu Em 31/05/2017 17:29, James Schneider

Re: count from multiple tables in a single query?

Hello James/Matthew, I was afraid to hear that. The models are unrelated and I do not want to take the trouble of dropping out of the ORM. Since it's a web-service I'm building, a work-around is to cache results, but I was challenged to find a single DB call solution and wanted to be sure that

count from multiple tables in a single query?

Hello, Is it possible to get the count of entries from multiple tables in a single query call? I'm looking at the official docs on aggregation and I can't find anything. For example assume I have the following 2 tables, class Author(models.Model): name = models.CharField(max_length=100)

Re: value of checkbox aren't saved in the form

Your checkbox fields on the form are "market" and "sector", but your "Parameters" model doesn't have fields with those names, and you aren't doing anything with the values from the form in your save() method. Where were you expecting those checkboxes to be saved? Cheers Tom On Wed, May 31,

Re: django.db.utils.OperationalError: server closed the connection unexpectedly

It's because you don't have PostgreSQL installed. The LitDB instructions say, among other things, "Make sure that you have a PostgreSQL database running and that you have permissions to create tables in that database". The LitDB installation instructions are quite brief, which is probably fine
