Django error: "'ChoiceField' object has no attribute 'is_hidden'"

Question

Django template throws 'AttributeError' when rendering..What I want to achive is that in the template the resolted forn will contain a select box with the values from the list below.

Here's the Forms.py file:

class CallForm (forms.ModelForm):

class Meta():
    model = Call
    widgets = {
         'employee_id' : forms.ChoiceField(choices=FormsTools.EmployeesToTuples(Employee.objects.all()))
    }

Explanation:

FormsTools.EmployeesToTuples(Employee.objects.all()) --> [(1, u'E1'), (2, u'E2'), (3, u'E3')]

Here is django's error:

Template error:
In template C:\virtualenv\#\#\templates\new_call.html, error at line 7
   'ChoiceField' object has no attribute 'is_hidden'
   1 : {% extends "base.html" %}


   2 : 


   3 : {% block content %}


   4 : 


   5 :         <form action="/NewCall/" method="post">{% csrf_token %}


   6 :             <ul>


   7 :                  {{ form.as_p }} 


   8 :             </ul>


   9 :             <input type="submit" name="submit" value="Add New Call">


   10 : 


   11 :         </form>


   12 : 


   13 : {% endblock %}

Exception Type: AttributeError at /NewCall/
Exception Value: 'ChoiceField' object has no attribute 'is_hidden'

What's cosing that 'AttributeError' ? How can it be fixed? Thanks.

ChoiceField is not a widget - it is a form field:

class CallForm (forms.ModelForm):
    employee_id = forms.ChoiceField(choices=FormsTools.EmployeesToTuples(Employee.objects.all()))

    class Meta:
        model = Call
        fields = ['employee_id']
