How to compare a value to a string with go templating - kubernetes-helm

Question

I want to loop through a values file to create a namespace and a networkpolicy in/for that namespace, except for default. I only want to create the policy and not the namespace for default since it is there by default.
values file:
namespaces:
- name: default
- name: test1
- name: test2
template file:
# Loop through the namespace names and create the namespaces
{{- range $namespaces := .Values.namespaces }}
{{- if ne "default" }}
apiVersion: v1
kind: Namespace
metadata:
name: {{ $namespaces.name }}
---
{{- end }}
{{- end }}
# Loop through the namespace names and create a network policy for those namespace
{{- range $namespaces := .Values.namespaces }}
---
kind: NetworkPolicy
apiVersion: networking.k8s.io/v1
metadata:
name: {{ $namespaces.name }}-networkpolicy
namespace: {{ $namespaces.name }}
spec:
podSelector: {}
ingress:
- from:
- namespaceSelector:
matchLabels:
name: {{ $namespaces.name }}
---
{{- end }}
The error I get is:
Error: UPGRADE FAILED: template: namespaces/templates/namespaces.yaml:3:7: executing "namespaces/templates/namespaces.yaml" at <ne>: wrong number of args for ne: want 2 got 1
It's probably something simple, but not seeing it. Hope someone can help.

This worked for me:
# Loop through the namespace names and create the namespaces
{{- range $namespaces := .Values.namespaces }}
{{- if ne $namespaces.name "default" }}
apiVersion: v1
kind: Namespace
metadata:
name: {{ $namespaces.name }}
---
{{- end }}
{{- end }}
# Loop through the namespace names and create a network policy for those namespace
{{- range $namespaces := .Values.namespaces }}
---
kind: NetworkPolicy
apiVersion: networking.k8s.io/v1
metadata:
name: {{ $namespaces.name }}-networkpolicy
namespace: {{ $namespaces.name }}
spec:
podSelector: {}
ingress:
- from:
- namespaceSelector:
matchLabels:
name: {{ $namespaces.name }}
---
{{- end }}
