Body
So, I have a model Project, and it has it's owner (User). Every project has it's own FilePathField, which depends on the owner (different 'match' parameter of FilePathField for different users). But this is not the only model working by this principle. I can rewrite the constructor (__init__ function) and pass the user there. Also I can create the Factory to create these models. What serious people do in this case? (when they must change the model's fields' properties depending on the user) Model: <pre><code>class Project(models.Model): project_file = models.FilePathField(_("Project file"), match='\.prj$', allow_files=True, allow_folders=False, recursive=True, path=PROJECTS_ROOT, null=False) name = models.CharField(_("Project name"), max_length=80, null=False) owner = models.ForeignKey(User, verbose_name=_("Owner"), null=False) </code></pre> Something like Factory function (just workaround): <pre><code>def getUserProjectForm(data, user=None): class ProjectForm(forms.ModelForm): def __init__(self, *args, **kwargs): forms.ModelForm.__init__(self, *args, **kwargs) try: user_folder = str(user.id) root_path = join(PROJECTS_ROOT, str(user_folder)) except Exception as e: user_folder = None root_path = PROJECTS_ROOT self.fields['project_file'].path = root_path self.filter_paths(user_folder) class Meta: model = Project fields = ['name', 'project_file'] def filter_paths(self, user_folder=None): import re if user_folder is not None and str(user_folder) != '': directory = join(PROJECTS_ROOT, str(user_folder)) else: directory = PROJECTS_ROOT regexp = re.compile('^%s(.+)$' % directory) temp_choices = [] db_choices = Project.objects.values_list('project_file', flat=True) for choice in self.fields['project_file'].choices: cur_match = regexp.match(choice[0]) if cur_match: if choice[0] in db_choices: continue cur_choice = cur_match.groups()[0] print "DEBUG" print choice[0], cur_choice, user_folder print "DEBUG" temp_choices.append((choice[0], cur_choice.replace(separator, "", 1))) self.fields['project_file'].choices = temp_choices </code></pre> Also. Maybe anyone knows how can I exclude the files which are already in the database? (the last cycle)

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
