In context i have form. When I put {{form}} in HTML page, everything is ok. Something like this:
<input id="id_sifraDrzave" maxlength="1024" name="sifraDrzave" type="text" /> How to get maxlength of field?

You can access it using form.fields.username.max_length in template.
Example (interactive shell):
>>> from django.forms.models import modelform_factory >>> from django.contrib.auth.models import User >>> UserForm = modelform_factory(User) >>> form = UserForm({}) >>> print form['username'] <input id="id_username" maxlength="30" name="username" type="text" /> >>> print form.fields['username'].max_length 30 >>> from django.template import Template, Context >>> print Template('{{ form.fields.username.max_length }}').render(Context({'form': form})) 30 Or use <specific_column>.field.max_length:
>>> print Template( ... '{% for column in form %}{{ column.field.max_length }} {% endfor %}' ... ).render(Context({'form': form})) 128 30 30 30 75

{% for column in columnMetaData%} alert('{{column}}'); alert('{{column.max_length}}'); {% endfor %} first alert displays:
<input id="id_sifraDrzave" maxlength="1024" name="sifraDrzave" type="text" />
second alert nothing...
