If I create a new file for each user, this won't be a good way. so please help me. (sorry I'm new in web programming). EDIT: $('

I have two models: League and Team . Team has a foreign key link to League . I want to be able to set choices available for the Team based on values stored in League . Specifically: class League(models.Model): number_of_teams = models.IntegerField() class Team(models.Model): league = models.ForeignKey(League) draft_slot = models.IntegerField(choices=[(i+1,i+1) for i in range(?????????)]) I recognize I cannot accurately define my draft_slot.choices in the Team model. So I would expect to set up Team like so: class Team(models.Model): league = models.ForeignKey(League) draft_slot = models

I'm trying to produce a table that will show the total maturity amounts for each financial institution that a plan has. A plan is the term I use for person. So each person can have multiple investments. I'm having trouble creating a table that will do this correctly. Currently I have a report that displays each investment sorted by Maturity Date, i.e. 2011,2012, etc. At the bottom I would like to place this summary table, but my query displays duplicates of each financial institution, due to being able to have multiple investments. My current query: list = Investment.objects.all().filter(plan

Is there any problem with the syntax in the following code, there is a error as Invalid block tag: 'else' {% ifequal chat_profile 1 %} {% extends "chatprofile/chat_profile1.html" %} {% else %} {% extends "chatprofile/chat_profile.html" %} {% endifequal %} The documentation states: If you use {% extends %} in a template, it must be the first template tag in that template. Template inheritance won't work, otherwise. So consider using a design where you can use {% include %} instead.
