12285	Confusing error message when ModelForm does not have model set	Erik Allik	Karen Tracey	"When instantiating a {{{ModelForm}}} whose {{{Meta.model}}} has not been set (i.e. the {{{ModelForm}}} class was extended instead of {{{Form}}}), the exception message is:

{{{'NoneType' object is not callable}}}

This message originates from {{{django/forms/models.py in __init__ line 218}}} that says {{{self.instance = opts.model()}}}.

Adding an {{{if}}} there with a decent message such as {{{""Model class not set for ModelForm""}}} would be the fix.
