Today I come across the requirement to have a link inside the help_text for ModelField. Hence I found this simple and fast solution and would like to share with you all. Before: my_field = models.CharField(max_length=10, help_text='Simple help text here') Solution: from django.utils.safestring import mark_safe my_field = models.CharField(max_length=10, help_text= mark_safe ('Simple help text here. <p>HTML code here</p>')) That's it and your help text will have this html code in place. Happy Coding!

Good day to all developers. Today encountered this issue where I do a simple queryset in DJango and hit with the following warning message:   RuntimeWarning: DateTimeField MessageContent.send_time received a naive datetime (2014-05-14 04:46:30.392000) while time zone support is active. How is this happen? This is due to I do the following datetime comparison in my queryset: import datetime Item.objects.filter(created = datetime.datetime.now()) The error is due to TIME_ZONE (in settings.py) is enabled by default. So the solution for this is pretty simple: 1) Either to set the TIME_ZONE to False in settings.py ( this will take away the timezone capability of your application) 2) or by comparing to timezone enabled datetime which the code as below: import datetime from django.utils.timezone import utc now = datetime.datetime.utcnow().replace(tzinfo=utc) Item.objects.filter(created = now) With this, the problem has been solved.

Its been long time after my last post. During my development in Django, I encountered this issue, where I don't know how to assign tuple value to choice argument in Django MultipleChoiceField. So here I would like to share on how to do this. Here are some information on the environment for this code: Django 1.6.1 doc: https://docs.djangoproject.com/en/1.6/ref/forms/fields/#multiplechoicefield Then looks into the forms.py: #1 import the models which use for MultipleChoiceField from TestChoice.models import Test #2 create a static CHOICES variable to hole this tuple, you can perform any normal Django query here. TEST_CHOICES = [[x.id, x.name] for x in Test.objects.all()] #3 If you would like to add extra choices, then you can do the following: TEST_CHOICES.insert(0, ['', "Empty"]) #4 The form field should looks like below, (required=False, only if you want this field to be optional) class TestForm(forms.Form):     test= forms.MultipleChoiceField...
