Hi,
This issue is fixed to me by instantiating the FormHelper() in forms.py.
I referred :
https://django-crispy-forms.readthedocs.io/en/latest/crispy_tag_forms.html
class ApplyGSPForm(ModelForm):
* helper = FormHelper()*
class Meta:
model = ApplyGSP
fields = ['model_name', 'model_no', 'os_ver', 'chipset',
'patch_level_to_be_applied', 'rel_cycle',
'applied_gsp_count', 'from_sas_url', 'to_sas_url',
'def_src_manifest', 'from_sw_version',
'to_sw_version', 'description']
exclude = ['user', 'requested_time', 'applied_security_patch_level']
Regards,
N.Dilip Kumar.
