Sometimes when you develop apps for other people, they like to define their own sets of "rules". For example, one customer might say the value of a certain field on a model might be valid when it is between 100 and 1000. Another customer might consider the same field valid only when the value is between 500 and 1000. That kind of validation is extremely difficult to do in a modelform's clean method like you would if you knew beforehand what the valid values were supposed to be. This app lets you create some boundaries for various arbitrary parameters that are tied to some other arbitrary model. Each customer can then define what the rule parameters will be for their particular organization. Usage: First create a file called dynamic_actions. Inside dynamic actions, you must register your rule class with the dynamic_rules site. The rule class must have the following attributes: key: a string to identify the rule class with the registry display_name: a name to use for the admin_form to show a readable name fields: a dictionary of field_names, and django form classes. This declares the parameters available. The following optional attribute is available: category: a grouping used as the header of an option group in the Key dropdown in the admin to make it easier to organize rules. If a category is not provided, the rule defaults to "uncategorized'. Additionally, the rule class must accept a rule_model and model_to_check as initialization arguments, and have a run method that accepts *args and **kwargs. To see the dynamic rules in action, syncdb from this project and fire up the admin. Create a rule tied to group_object_id: 1 (i.e. customer 1) and content type: 'customer' Add a ModelToCheck model from the sample app that has a value that violates your rule. Check the runserver console and see that the violation printed. This is best used in conjunction with django-dynamic-validation which lets you track and store violations to the rules, or django-dynamic-manipulation which lets you manipulate other data because of a triggered rule. - http://pypi.python.org/pypi/django-dynamic-validation - http://pypi.python.org/pypi/django-dynamic-manipulation Recent Updates -------------- 1/24/2012 Updated dynamic_rules to use latest version of django-class-registry (0.0.3) which handles the registry like a dictionary. 'dynamic_rules.site' should now be referred to as 'dynamic_rule.rule_registry' however, you can access 'site' for a while. We just believe 'rule_registry' is a much better name.
