Re: Not reading from TEMPLATE_DIRS in settings.py
Have you checked the permissions of the directory and template files? run ls -l in the parent directory of the template folder and inside the folder itself . madala wrote: > Have followed tutorial 2 instructions carefully.

Unique Id issue
Hi all, Am in a bit of a fix which I put myself in,I have the following models: class Town(...): name = models.CharField(unique=true) province = models.foreignKey(Province) class Area(): name = models.CharField(unique=true,max_length=120) town = models.CharField(Town) The problem here is I made the assumption that an area name is unique,unfortunatly after deploying ,I have just realized that some towns have the same area names so I can't have example area x in town A as well as area x in town B. We have already deployed and have 575 users so far,is there any safe way of removing the unique key constraint on Area model without damaging the records which are already there? -- You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Implementing a monitoring system with django.
Depending on what you need for the graphs,have a look at flot,jqplot or rapheal.js(heavy).There is also high charts althought there are some licensing issues you may want to avoid. If you get stuck with the charts,let me know..am running some.

Re: 1.5 custom user model: Add User with default UserCreationForm results in "no such table: auth_user"
Thanks alot Eric and Russel,I was also stuck on this. I can also confirm that you have to override clean_username in addition to the class Meta ,otherwise you will get a database error.
