How can I create a sequence number for a data set in the model?

I want to create a sequence of values for a column in one of my tables in the model class. The sequence number is updated every time a new rows is added to the table. The sequence number is reset to zero when a foreign key value changes. Is this possible, and how would I do it? Here is the

Okay... and how is the SQL in the back? Does it do joins between the two tables or what? That slows down a lot no? On Apr 6, 9:11 am, Ejah wrote: > Hi, > You must add your app to the installed apps. Editting through the > admin requires you to register an admin form for

Re: calculate default values for fields based on the content of other fields

Capture the value from the form submitted into a variable. Use straight sql to query the table and the field that you are interested in and translate the field based on sql. It is not necessary to only use the ORM. This is an abstraction layer, and sometimes the restrictions based upon

You redeclaring your Model classes, and you don't need to. By doing so, the 'self' inside your __unicode__ function refers to a property that isn't defined (since you redeclared the original class that had the property). Here is what the model should look like: http://codepad.org/P21ZNkZY On Fri,

I'm trying to store temporary cart in session, but cart items disappear after 3-4 page reloads. This is simplified version of my code, that reproduces the issue: """ class C(object): ITEMS = {} def pprint(self): return str(self.ITEMS) class I(dict): pass def

Jerry, You'll want to be sure your method is defined as: def __unicode__(self): return self.name # I'm using 'name' as an example field with double underscores on both sides of 'unicode' instead of just in front of it. Hope this helps, Jonathan On Fri, Apr 6, 2012 at 12:13 PM, jk121960

I think there are two sensible approaches to this: 1. Write some customer javaScript and set the values of your form fields based on the first field 2. Use a form wizard, form 1 contains the base word, form 2 contains all the various variants. As you generate form 2 after 1, you are able to use
