model - How to make the user-oriented form in django? -


so, have model project, , has it's owner (user). every project has it's own filepathfield, depends on owner (different 'match' parameter of filepathfield different users). not model working principle.

i can rewrite constructor (__init__ function) , pass user there.

also can create factory create these models.

what serious people in case? (when must change model's fields' properties depending on user)

model:

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)

something factory function (just workaround):

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 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 not none , 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)             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

also. maybe knows how can exclude files in database? (the last cycle)

vb.net - Virtual Keyboard commands -

i wondering difference between virtual these keyboard commands is: keyeventf_extendedkey , keyeventf_keyup is. everywhere have looked gives me description based off integers , not want know each of them does. you've tagged question vb.net, these have nothing @ vb.net. they're constants defined in windows header files, use win32 api functions. as far difference, can't tell looking @ values. individual values not particularly important, that's why named identifiers used. what's important used , documentation functions tells mean. the first one, keyeventf_extendedkey , used keybdinput structure (which used along e.g. sendinput function) pass information synthesized keyboard input. if flag used, means scan code should interpreted extended key. technically, means scan code preceded prefix byte value 224 (&he0 in hexadecimal notation). the second one, keyeventf_keyup , 1 of flags available use structure. means key being released (going up)...
