Given the model:
===========================================
myText = models.TextField(blank=True)
===========================================
In case this TextField has no text I want to hide it from my form.
Template code:
===========================================
{% if form.myText.text %}
<label for="id_myText">My text:</label> {{form.myText }}
{% else %}
No text yet.
{% endif %}
===========================================
But then saving the form gives an error saying it wants to save a NULL
value in a field that cannot be NULL. A solution could be adding
'null=True' to the field:
===========================================
myText = models.TextField(blank=True, null=True)
===========================================
But this is discouraged by Django:
http://www.djangoproject.com/documentation/model_api/#null
"Avoid using null on string-based fields such as CharField and
TextField unless you have an excellent reason. If a string-based field
has null=True, that means it has two possible values for "no data":
NULL, and the empty string. In most cases, it's redundant to have two
possible values for "no data;" Django convention is to use the empty
string, not NULL."
What would be the proper way to do this?
