Re: How 2 access the Primary model's ID in the Foreign model??

2019-01-01 Thread mazz ahmed

Hello,
hope everyone doing well. I am working on tornado framework. I want to use
admin panel for that app but I am getting a single solution using
Django alongside of tornado for admin panel. I want to use some package in
the tornado which gives me admin panel.
If anyone knows let me know Please.
Thanks&Regars Mazz Ahmed

Re: MySQL accepts 0 for a primary key but Django does not

Hi Simo


My custom app has no particular structure - its really just a collection of 
files and utilities that are commonly used across multiple apps.  It gets 
imported, along with all the others, in the settings file.

When I follow your suggestion of just referring to "custom", I get this 
error:

Posting data from templates to views.py without using forms.

2019-01-01 Thread Surajeet Das

Well , I want to post data from templates to views.py by clicking a button 
without using forms. Basically the button should not be of type submit 
because I don't want the page to be refreshed .I want to view the data from 
database after the query in the same page.

Hi Surjeet,

Then you should rely on ajax call or angularjs using ng-click.
