python - django form doesn't show up or object takes no parameters error -

i add form on website firms list themselves. it's kind of local business directory wanted build django. when try show form on "add-business" page 2 different results.

the first result is: if use {{ form.as_p }} doesn't show form.

the second result is: if try build form own html inputs, says object() takes no parameters, pointing @ request.post within view (form = addbusinessform(request.post)) can see below.

i don't know wrong. view same django docs.

my model :

class firma(models.model):     user = models.foreignkey(user, on_delete=models.cascade)     firm_name = models.charfield(max_length=120)     firm_adress = models.charfield(max_length=200)     firm_city = models.charfield(max_length=100)     firm_desc = models.textfield(max_length=2000)     firm_email = models.emailfield(max_length=80, unique=true,validators=[validate_email, ])     firm_phone = models.charfield(max_length=20)     firm_website = models.charfield(max_length=60, validators=[urlvalidator()])     firm_add_date = models.datetimefield(auto_now_add=true)     firm_last_edited = models.datetimefield(auto_now=true)     status_firm = models.charfield(max_length=40, default='active')     status_site = models.charfield(max_length=40, default='pending')     slug = models.slugfield(max_length=140, unique=true) 

my form:

class addbusinessform():     firma_name = forms.charfield(max_length=80, required=true, help_text='required.')     firm_adress = forms.charfield(max_length=150, required=true, help_text='required.')     firm_city = forms.charfield(max_length=50, required=true, help_text='required.')     firm_desc = forms.charfield(widget=forms.textarea, required=true, help_text='required. company')     firm_email = forms.emailfield(max_length=80, required=true, help_text='required. please write valid email')     firm_phone = forms.charfield(max_length=150, required=true, help_text='required.')     firm_website = forms.charfield(max_length=80, required=true, help_text='required.')      class meta:         model = firma         fields = ('firm_name', 'firm_adres','firm_city',                  'firm_desc','firm_email','firm_telefon','firm_website') 

my url :

url(r'add-business/$',views.add_business, name='add_business'), 

my view:

def add_business(request):      if request.method == 'post':         form = addbusinessform(request.post)         if form.is_valid():             form.save()             return redirect('memberships/dashboard')     else:         form = addbusinessform()     return render(request, 'directory/add-business.html', {'form': form}) 

your model form should subclass of forms.modelform:

class addbusinessform(forms.modelform):
