go-netbox/v4 - custom fields filtering request

[katt-999]

Hello,

I'm actually trying to filter IpAddresses using IpamAPI.IpamIpAddressesList, I can't find a way to filter my results using custom fields.

How can I do that ?

Regards, Guillaume

I didn't saw issue that #210, but, I finally manage to filter witn custom fields by using Q() method :

func (r *NetboxClient) GetPrefixWithQuery(Q string, ctx context.Context) (*netbox.PaginatedPrefixList, error) {
	getPrefix, _, err := r.client.IpamAPI.IpamPrefixesList(ctx).Q(Q).Execute()
	if err != nil {
		return nil, err
	}
	return getPrefix, nil
}

You can call a filter with a custom field :

req, err := NetboxClient.GetPrefixWithQuery("&cf_customfield1=randomvalue", ctx)

But in the current release there is an issue on Q(), all special chars are HTTP escaped, and will result with a HTTP request like this :

http://netbox.central.sandbox.airnity.private/api/ipam/prefixes/?q=%26cf_customfield1%3Drandomvalue

I have made some change on my side on client.go file on go-netbox/v4 :

original from package :

	query := url.Query()
	for k, v := range queryParams {
		for _, iv := range v {
			query.Add(k, iv)
		}
	}

	// Encode the parameters.
	url.RawQuery = queryParamSplit.ReplaceAllStringFunc(query.Encode(), func(s string) string {
		pieces := strings.Split(s, "=")
		pieces[0] = queryDescape.Replace(pieces[0])
		return strings.Join(pieces, "=")
	})

To :

    // Adding Query Param with special handling for 'q' parameter
    query := url.Query()
    var qParam string
    var hasQParam bool
    
    for k, v := range queryParams {
        for _, iv := range v {
            if k == "q" {
                // Special handling for 'q' parameter to avoid double URL encoding
                qParam = iv
                hasQParam = true
            } else {
                query.Add(k, iv)
            }
        }
    }
    
    // Encode the normal parameters
    encodedQuery := queryParamSplit.ReplaceAllStringFunc(query.Encode(), func(s string) string {
        pieces := strings.Split(s, "=")
        pieces[0] = queryDescape.Replace(pieces[0])
        return strings.Join(pieces, "=")
    })
    
    // Build final query string with special handling for 'q'
    if hasQParam {
        if encodedQuery != "" {
            url.RawQuery = encodedQuery + "&q=" + qParam
        } else {
            url.RawQuery = "q=" + qParam
        }
    } else {
        url.RawQuery = encodedQuery
    }

I have made change on the client.mustache template and regenerate library on my side. It works like a charm, but I don't found them on that repository, so can't PR for that. Any idea how I can push and PR that change @nutgood ?

3 weeks since my last message, any mainteners of that repository can answer ?
