How to set default value for FloatField in django model
django, mysql, python
Solution
Your code should work. Perhaps something is setting the empty value to a non-null value (like an empty string). I'd have to see the full error message.
Since this is an old thread, I'm going to post the answer to the question I came here for, "How do you set FloatField default to Null in the database?"
cost = models.FloatField(null=True, blank=True, default=None)
Problem
How can I set a default value for `FloatField` in django. Initially when I had created the model and declared the float field as: ``` cost = models.FloatField(null=True, blank=True) ``` and db also created successfully through south migration. But now when I am trying to do edit on that field using the html form, and no value is entered in the cost field, in the form its throwing `value error`. Thus I think if I can set a default value for cost field it may fix the problem. But I don't know how to set a default value for `FloatField` in `django`.
