Reverse fields

Pyston by default automaticaly creates reverse objects atomically if you add data to the request. For example if you add issue to the user creation request issue is automatically created:

{
    "email": "user1@example.cz",
    "leading_issue": {
        "name": "example"
    }
}

You can turn it off with parameter PYSTON_AUTO_REVERSE set to False.

Forms

You can define reverse fields in your form manually (it works with turned off auto reverse too). As example we can use user form from example application:

from pyston.forms import RESTModelForm, ReverseOneToOneField, ReverseStructuredManyField


class UserForm(RESTModelForm):

    watched_issues = ReverseStructuredManyField('watched_issues')
    created_issues_renamed = ReverseStructuredManyField('created_issues')
    solving_issue_renamed = ReverseOneToOneField('solving_issue')
    leading_issue_renamed = ReverseOneToOneField('leading_issue')

Fields

There are several fields:

• ReverseSingleField - For reverse one to many relation with posibility to add one object
• ReverseOneToOneField - For reverse one to one relation
• ReverseMultipleField - For reverse one to many relation with posibility to add more objects in list
• ReverseStructuredMultipleField - For reverse one to many relation with posibility to add more objects in list or dictionary with parameters ‘add’, ‘remove’ or ‘set’
