You are probably looking for a many-to-many relationship using an intermediary table: https://docs.djangoproject.com/en/1.8/topics/db/models/#intermediary-manytomany -James On Aug 6, 2015 3:06 AM, "Holland_zwz" wrote: > Sometimes table have more than one foreign key reference to other tables. >

Hi Stuart, Are you interested in participating in writing code for Speedy Mail Software? And thanks for the link to pyjs, I was not aware of this libraby. So I guess we can just use it and we don't have to create it. I want to use pyjs also for Speedy Mail Software. Please let me know if you can p

Re: how to descript the many to one relationship in model when there are more than 1 tables

Hi James, Thanks for reply. But i am not got the main point. The problem is the table C's oid column data comes from A or B. I think this is not same as many-to-many relationships. Thanks -hollandz 在 2015年8月6日星期四 UTC+8下午6:14:25，James Schneider写道： > > You are probably looking for a m

Issue when rendering manually a form's HiddenInput

So, I'm trying to use inputs with the *hidden* attr. I have my form class ( *IndexForm*) that has this: field = HiddenInput() Then, I pass the instance of IndexForm (*index_form*) to the template, and manually render the field (*index_form.field*). It is alright, but then, in the HTML, the render

Adding a sidebar to the admin

I'd like to add a sidebar on the left side of all admin pages (including change_list, change_details, etc), with a list of all my models. In other words, I'd like to move the index with a list of models into a sidebar on the left. After poking around the docs and templates a bit, it seems that I'd

Hi Joey. I was trying to understand your models, relationship and logic behind them. How you are supposed to create a League object? I tried creating as follows. p=Player.objects.create(name='Shahid Afridi') l=League(name='FootballDevils') l.save() // not calling directly objects.create on Leagu

What Did I Do Right? (url and domain name change)

I have 1 model from my django project up and running on django. Before adding more models and content, I wanted to use my actual domain name, instead of whatever.herokuapp.com. So after I got that straight, I realized that while the home page was mysite.com, the links were still mystite.herokua

Re: auto_created getting ignored by makemigrations

@zubair: The reason Django complained about wanting to create the LeaguePlayer intermediary model when you used "add()" is because you didn't have auto_created=True. That allows Django to link the objects correctly via the intermediary model automatically without populating any of the extra fields
