ida_ida not defined, should replace with idaapi

@classmethod
def update(self, ctx):
    try:
        if ctx.form_type == idaapi.BWN_DISASM:
            return idaapi.AST_ENABLE_FOR_FORM
    else:
        return idaapi.AST_DISABLE_FOR_FORM
except Exception as e:
    # Add exception for main menu on >= IDA 7.0
    return idaapi.AST_ENABLE_ALWAYS
@classmethod
def update(self, ctx):
    try:
        if ctx.widget_type == idaapi.BWN_DISASM:
            return idaapi.AST_ENABLE_FOR_FORM
    else:
        return idaapi.AST_DISABLE_FOR_FORM
except Exception as e:
    # Add exception for main menu on >= IDA 7.0
    return idaapi.AST_ENABLE_ALWAYS

ctx.form_type -> ctx.widget_type
