Django Field Regex Validation -

-

i trying create model store hashtag.

the validator doesn't seem working, making field accept inputs, , can't find solution.

here model:

class hashtags(models.model):     hashtag_validator = regexvalidator(r'^[#](\w+)$', "hashtag doesn't comply.")     hashtag_id = models.autofield(primary_key=true)     hashtag_text = models.charfield(max_length=100, validators=[hashtag_validator],   unique=true)  def get_id(self):     return self.hashtag_id  def get_text(self):     return self.hashtag_text

you can alter below given code see working

hashtag_validator = charfield(         max_length=50,         required=true, #if want field mandatory         validators=[             regexvalidator(                 regex='^[#](\w+)$',                 message='hashtag doesnt comply',             ),         ]     )

hope helps!!

if causing problem can try writing own validator

from django.core.exceptions import validationerror import re def validate_hash(value):     reg = re.compile('^[#](\w+)$')     if !reg.match(value) :         raise validationerror(u'%s hashtag doesnot comply' % value)

and change model field 

hashtag_validator = models.charfield(validators=[validate_hash])

i've been using 2 methods render data. the first one: function name($id,$name){ return '<div id="'.$id.'">'.$name.'</div>'; } echo implode($pdo->query("select id,name user")->fetchall(pdo::fetch_func,'name')); the second one: $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); foreach($users $user){ echo name($user->id,$user->name); } i don't understand how pdo::fetch_func works. tried figure out. however, not well-documented. could please explain fetch mode? , also, 1 performs better? thank you. both methods wrong , have learn how use templates , how separate business logic presentation logic. $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); tpl::assign('users', $users); is code business logic part. then in template <?php foreach $users $row): ?> <div id="<?=$...
