[FIXED] How can I make one of the fields in admin.TabularInline conditional?

Issue

Is there a way how can I make one of the fields in admin.TabularInline conditional?

for example

class ParameterInline(admin.TabularInline):
    form = ParameterForm
    fields = ["ParameterA", "ParameterB"]

What if I wanted to display the ParameterB only if something else was set to, for example, True?

Thanks in advance.

Solution

You can achieve this by overriding the get_fields method:

class ParameterInline(admin.TabularInline):
    form = ParameterForm
    fields = ["ParameterA"]
    
    def get_fields(self, request, obj=None):
        fields = super(ParameterInline, self).get_fields(request=request, obj=obj)
        if True:
            return fields + ['ParameterB']
        return fields
