Hello, I think the source of your frustration is that you started on the wrong track. If you create a global variable here, *all* your users will see the same fields. I guess it’s not really the thing you want.
You have several other options here: 1) Add a user setting in the database If you create a separate model with your User model as its primary key (thus, creating a OneToOne relation between a User and Setting), you can store these values in the database, this way persisting it between user sessions 2) Session variables You can use Django’s session framework. Here[1] is some help on this. 3) Cache This can be similar to 1) or 2), or somewhat the combination of the two. This way you store such values in a cache, like MemCached. This solves some possible garbage collection problems and database storage issues. More on accessing the cache here[2]. Hope this helps.
